<p>As our planet warms and urban areas expand, the threat of mosquito-borne diseases such as malaria and dengue is escalating, reaching regions previously untouched by these dangerous illnesses. </p>



<p>Now, with over half of the global population at risk, these <a href="https://www.earth.com/news/tick-mosquito-borne-disease-spreading/" target="_blank" rel="noreferrer noopener">diseases</a> have quickly become a critical concern worldwide.</p>



<h2 class="wp-block-heading" id="h-the-global-spread-of-disease-vectors">The global spread of disease vectors</h2>



<p><a href="https://www.earth.com/news/how-mosquitoes-find-tasty-humans-from-hundreds-of-meters-away/" target="_blank" rel="noreferrer noopener">Mosquitoes</a>, the primary vectors for diseases like malaria and dengue, are finding suitable habitats far beyond their traditional tropical and subtropical locales. This expansion is due in part to longer and hotter seasons that allow mosquito larvae to survive and thrive in new areas. </p>



<p>As these insects invade places like northern Europe, Asia, North America, and Australia, local populations face increased risks - often in areas where people lack immunity and public health systems are unprepared.</p>



<h2 class="wp-block-heading" id="h-insights-from-the-front-lines-of-research">Insights from the front lines of research</h2>



<p>At the upcoming ESCMID Global Congress in Barcelona, <a href="https://www.icrea.cat/" target="_blank" rel="noreferrer noopener">ICREA</a> Professor Rachel Lowe will present her latest findings on this issue. </p>



<p>Professor Lowe, who leads the global health resilience group at the Barcelona Supercomputing Center in Spain, will discuss the dramatic shifts in vector-borne disease patterns and the essential role of enhanced surveillance and early warning systems.</p>



<p>"Droughts and floods linked to <a href="https://www.earth.com/news/climate-change-is-great-for-mosquitoes/" target="_blank" rel="noreferrer noopener">climate change</a> can lead to greater transmission of the virus, with stored water providing additional mosquito breeding sites," noted Professor Lowe. Her research in the Caribbean shows that extreme climate conditions such as drought followed by excessive rainfall can significantly increase the likelihood of dengue outbreaks. </p>



<p>These findings underscore the need for comprehensive assessments of vector-borne disease risks and preparedness for future outbreaks.</p>



<h2 class="wp-block-heading" id="h-the-rise-of-dengue">The rise of dengue</h2>



<p>Dengue, which is spread by day-biting mosquitoes, has dramatically increased in spread and frequency. </p>



<p>Since 2000, the most hospitable years for dengue transmission have facilitated the mosquito's invasion into 13 European countries, including France, Italy, and Spain, with local disease outbreaks reported as recently as 2023.</p>



<p>Furthermore, the number of global <a href="https://www.earth.com/news/dengue-fever-modified-mosquitoes/" target="_blank" rel="noreferrer noopener">dengue</a> cases reported surged from 500,000 in 2000 to over five million in 2019. This makes dengue the most rapidly spreading mosquito-borne viral disease in the world.</p>



<h2 class="wp-block-heading" id="h-projecting-future-mosquito-disease-outbreaks">Projecting future mosquito disease outbreaks</h2>



<p>The data suggests a daunting future if current trends continue. With <a href="https://www.earth.com/news/global-warming-dengue-fever/" target="_blank" rel="noreferrer noopener">global warming</a> and population growth proceeding unchecked, projections are increasingly alarming. They indicate that up to 4.7 billion additional people could be at risk of contracting malaria and dengue by the end of the century.</p>



<p>On the other hand, if global warming is limited to an ambitious goal of a 1°C increase, the number of people at risk could be significantly reduced, although it would still be substantial.</p>



<h2 class="wp-block-heading" id="h-the-role-of-el-nino-in-mosquito-disease-outbreaks">The role of el niño in mosquito disease outbreaks </h2>



<p>El Niño events, which occur every 2-7 years, exacerbate these issues by creating hotter and wetter conditions that are ideal for mosquito breeding.</p>



<p>Professor Lowe highlights the direct link between these climatic fluctuations and disease outbreaks. Specifically, the Zika pandemic in Brazil, which emerged during an El Niño phase in 2015, was a direct result of climate conditions.</p>



<p>Furthermore, the current strength of El Niño suggests that these challenging conditions are likely to continue.</p>



<h2 class="wp-block-heading" id="h-climate-change-and-mosquito-borne-diseases">Climate change and mosquito-borne diseases</h2>



<p>Professor Lowe stresses the urgency of addressing climate change to mitigate the spread of these diseases. "With climate change seeming so difficult to address, we can expect to see more cases and possibly deaths from diseases such as dengue and malaria across mainland Europe." </p>



<p>Therefore, proactive measures, including robust surveillance systems and early interventions, are crucial to preventing outbreaks.</p>



<p>Researchers are now using advanced technologies to better anticipate disease outbreaks. These technologies include supercomputers, drones for identifying breeding sites, and community-based reporting systems to direct resources effectively.</p>



<p>"By analyzing weather patterns and gathering information from local communities and health officials, we are hoping to give communities time to prepare and protect themselves," said Professor Lowe. </p>



<h2 class="wp-block-heading" id="h-united-efforts-are-needed">United efforts are needed </h2>



<p>Ultimately, the most effective strategy to reduce the risk of disease spread is to dramatically curb emissions and address the root causes of climate change.</p>



<p>As mosquito-borne diseases expand their reach, the need for global cooperation and innovative solutions has never been greater. </p>



<p>Through informed research, proactive planning, and international collaboration, we can help to shield vulnerable populations from these escalating health threats.</p>

Mosquito-borne diseases are a growing threat in a warming world

As our planet warms and urban areas expand, the threat...

<p>The mating strategies of squid are determined by their date of birth, according to a recent study from the <a href="https://www.u-tokyo.ac.jp/ja/index.html">University of Tokyo</a>. The research sheds new light on the reproductive tactics of male spear squids.</p>



<p>While humans might consider how their birth date influences personality or destiny, for these marine creatures, the timing of birth crucially influences their approach to mating.</p>



<p>"Alternative reproductive tactics (ARTs) are discontinuous phenotypes associated with reproduction, observed in males of many species," wrote the study authors. "Typically, large males adopt a tactic of competing with rivals for mating, while small males adopt a tactic of stealing fertilization opportunities from the large males."</p>



<p>"The ‘birth date hypothesis,' proposing that the date of birth influences the determination of each male's reproductive tactic, has been tested only in teleost fish to date."</p>



<h2 class="wp-block-heading" id="h-a-date-with-destiny">A date with destiny</h2>



<p>Scientifically known as Heterololigo bleekeri, spear squids adopt one of two mating strategies. Males born earlier in the breeding season grow larger and become "consorts," aggressively competing with rivals to mate and protect females during egg-laying. </p>



<p>On the other hand, males that hatch later in the season are typically smaller when they start reproducing and choose a "sneaker" tactic. These squids deposit their sperm on the outside of a female near where she lays her eggs - hoping to fertilize them.</p>



<h2 class="wp-block-heading" id="h-the-unchanging-nature-of-squid-mating-tactics">The unchanging nature of squid mating tactics</h2>



<p>The experts discovered that once a male squid's mating tactic is set by his birth date, it remains unchanged throughout his life. </p>



<p>This pattern is so robust that even if an early-born squid could theoretically adopt the sneaker strategy during the early breeding season due to size, he would instead delay his maturation to grow sufficiently large to become a consort. </p>



<p>"The presence of large immature males appears to support this (i.e. these immature males may have been delaying their maturation in a non-reproductive state as a tactic to become a successful consort later in the season)," noted the researchers.</p>



<p>This all-or-nothing approach to mating tactics is remarkably consistent, with <a href="https://www.earth.com/news/scientists-have-created-a-transparent-squid-allowing-them-to-see-inside-while-its-still-alive/" target="_blank" rel="noreferrer noopener">squids</a> born around early July displaying a fifty-fifty chance of adopting either strategy.</p>



<h2 class="wp-block-heading" id="h-ecological-and-commercial-ramifications">Ecological and commercial ramifications</h2>



<p>Professor Yoko Iwata of the Atmosphere and Ocean Research Institute at the University of Tokyo explained the significance of these findings. "The hatching date determines the whole life trajectory in this species. The difference in hatch date means that the squid experience different environmental conditions in early life, which may influence their growth trajectory." </p>



<p>She further elaborated on the potential repercussions of environmental changes, such as ocean heat waves, on <a href="https://www.earth.com/news/squid-have-unexpected-camouflage-ability/" target="_blank" rel="noreferrer noopener">squid</a> sizes and their mating tactics, which could significantly impact commercial fishing yields.</p>



<p>The research is notable as it extends the "birth date hypothesis" to aquatic invertebrates, suggesting its broader applicability across more animal species.</p>



<h2 class="wp-block-heading">New insights into squid growth rates</h2>



<p>The team analyzed more than 350 specimens collected between 2020 and 2023, sourced directly or from commercial catches. The results challenge previous beliefs about the growth rates among different squid mating types.</p>



<p>Although environmental factors like water temperature are well-known to influence squid development, the researchers discovered surprisingly little variation in the early life growth rates of consorts and sneakers.</p>



<p>This discovery raises new questions about the factors influencing the growth and reproduction of male spear squids.</p>



<h2 class="wp-block-heading">The significance of statoliths in squid research</h2>



<p>Looking ahead, the researchers will turn their attention to the statolith, a key structure within the squid that documents daily growth in a manner akin to tree rings. </p>



<p>By analyzing microelements within the statolith, experts can determine the age of squids as well as the environmental conditions they encountered during various life stages.</p>



<p>Professor Iwata expressed excitement about the potential implications of their findings. "I am interested in the evolution of animal survival and reproduction strategies, or life history; and also phenotypic plasticity, that is, how individuals respond to environmental changes. Spear squid provide an ideal model for studying the impact of environmental and ecological conditions on life history."</p>



<p>The research will further illuminate how early life conditions affect squid mating tactics and provide deeper insights into how other marine species adapt to environmental changes.</p>



<p>The study is published in the journal <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2024.0156" target="_blank" rel="noreferrer noopener">Proceedings of the Royal Society B Biological Sciences</a>.</p>

Squid mating tactics are determined by birth date

The mating strategies of squid are determined by their date...

<p>Space is a never-ending source of fascination for us Earthlings. From the twinkle of stars to swirling galaxies, there's always something new to discover. Scientists at <a href="https://www.mit.edu" target="_blank" rel="noreferrer noopener">MIT</a> recently announced the discovery of a new space molecule in the dust clouds where stars are born.</p>



<h2 class="wp-block-heading" id="h-molecules-in-space">Molecules in space</h2>



<p>Space is not just an empty void; it's filled with diverse chemical compounds. It contains simple life-essential molecules like water (H2O) and carbon dioxide (CO2). Additionally, <a href="https://www.earth.com/news/astronomers-map-the-dark-chemistry-of-outer-space/" target="_blank" rel="noreferrer noopener">space</a> harbors more complex organic molecules, some similar to industrial solvents.</p>



<p>The interactions of compounds in the interstellar medium are intriguing. They transform in ways that may reveal how life's building blocks originated. Interestingly, these processes could provide clues about the emergence of life itself.</p>



<h2 class="wp-block-heading" id="h-space-experts-hunt-for-new-molecule">Space experts hunt for new molecule</h2>



<p>A research team at MIT, led by Professor Brett McGuire, is actively studying the molecular composition of the vast interstellar clouds where stars and planetary systems form. This work aims to answer fundamental questions about the chemical processes that occur during these formative stages. </p>



<p>"Our group tries to understand what molecules are present in regions of <a href="https://phys.org/tags/space/">space</a> where stars and solar systems will eventually take shape," explained Zachary T.P. Fried, a graduate student in the McGuire group and the lead author of the publication. </p>



<p>"This allows us to piece together how chemistry evolves alongside the process of star and planet formation. We do this by looking at the rotational spectra of molecules, the unique patterns of light they give off as they tumble end-over-end in space."</p>



<h2 class="wp-block-heading" id="h-spectral-signature">Spectral signature</h2>



<p>Understanding chemical environments at early stages is essential. The molecules in these environments affect the properties of forming <a href="https://www.earth.com/news/complex-organic-molecules-discovered-surrounding-newborn-star-iras-23385/" target="_blank" rel="noreferrer noopener">planets</a> and their ability to support life. </p>



<p>The MIT team uses powerful telescopes to observe electromagnetic radiation from deep space molecules. Each molecule interacts with light uniquely, creating a distinct spectral signature. This signature helps identify the molecule.</p>



<p>The research process begins by selecting a target molecule. Scientists analyze the molecule in a laboratory setting to precisely determine its spectral signature. They then use telescopes to scan star-forming regions, searching for a match between the laboratory-derived signature and the telescopic observations. A positive match confirms the presence of the target molecule within the distant interstellar cloud.</p>



<h2 class="wp-block-heading" id="h-2-methoxyethanol">2-methoxyethanol</h2>



<p>In 2023, an AI-driven computer program played a key role in astronomical research. It identified a molecule called 2-methoxyethanol as a promising target for observation. This molecule is a complex organic compound, not commonly found in everyday products.</p>



<p>"There are a number of 'methoxy' molecules in space, like dimethyl ether, methoxymethanol, ethyl methyl ether, and methyl formate, but 2-methoxyethanol would be the largest and most complex ever seen," said Fried.</p>



<p>After collaborating with global scientists, the MIT team predicted the molecule's spectral signature. They then embarked on an intensive search effort. To detect the faint signals emitted by molecules in distant space, they utilized the Atacama Large Millimeter/submillimeter Array (ALMA), a state-of-the-art international observatory located in Chile's high-altitude Atacama Desert. </p>



<p>ALMA's exceptional sensitivity and resolution allow astronomers to probe the depths of the universe in search of even the most subtle molecular emissions. The team meticulously analyzed the vast dataset generated by ALMA, searching for the specific spectral pattern associated with 2-methoxyethanol.&nbsp;</p>



<p>"Ultimately, we observed 25 rotational lines of 2-methoxyethanol that lined up with the <a href="https://phys.org/tags/molecular+signal/">molecular signal</a> observed toward NGC 6334I (the barcode matched), thus resulting in a secure detection of 2-methoxyethanol in this source," said Fried. </p>



<p>"This allowed us to then derive physical parameters of the molecule toward NGC 6334I, such as its abundance and excitation temperature. It also enabled an investigation of the possible chemical formation pathways from known interstellar precursors."</p>



<h2 class="wp-block-heading" id="h-significance-of-new-space-molecule">Significance of new space molecule</h2>



<p>The vast clouds of gas and dust where stars are born act as complex chemical environments. Within these clouds, a diverse array of molecules exist, ranging from simple compounds to larger, more intricate structures. </p>



<p>These molecules represent the fundamental building blocks from which <a href="https://www.earth.com/news/building-blocks-of-life-found-in-a-galaxy-12-billion-light-years-away/" target="_blank" rel="noreferrer noopener">planets</a>, asteroids, and potentially even the precursors to life can form. The presence of increasingly complex molecules within these regions suggests a wider range of possibilities for the types of environments that can develop within emerging planetary systems.</p>



<p>The discovery of 2-methoxyethanol, a relatively large and complex organic molecule, highlights the surprising chemical processes that can occur in the seemingly harsh conditions of deep space. This discovery suggests that even in the coldest depths of the cosmos, the conditions exist to create molecules of significant complexity.</p>



<p>"Continued observations of large molecules and subsequent derivations of their abundances allows us to advance our knowledge of how efficiently large molecules can form and by which specific reactions they may be produced," said Fried.</p>



<p>"Additionally, since we detected this molecule in NGC 6334I but not in IRAS 16293-2422B, we were presented with a unique opportunity to look into how the differing physical conditions of these two sources may be affecting the chemistry that can occur."</p>



<p>The study is published in the journal <em><a href="https://iopscience.iop.org/article/10.3847/2041-8213/ad37ff" target="_blank" rel="noreferrer noopener">The Astrophysical Journal Letters</a></em>.</p>

New molecule detected in space where stars are born

Space is a never-ending source of fascination for us Earthlings....

<p>Did you know that the very space station orbiting miles above our heads is helping us better understand how our planet's climate is changing? It might sound surprising, but the International Space Station (<a href="https://www.nasa.gov/international-space-station/" target="_blank" rel="noreferrer noopener">ISS</a>) isn't just about exploring the cosmos – it's about protecting our home planet too.</p>



<h2 class="wp-block-heading" id="h-iss-climate-data-collection">ISS climate data collection</h2>



<p>Climate change is a pressing issue impacting every corner of the globe. From experiencing increasingly scorching summers to witnessing unpredictable and often destructive weather patterns, the consequences are undeniable. To effectively prepare communities for these ongoing shifts, scientists require a wealth of accurate data. </p>



<p>The International Space Station, with its unique vantage point, plays a critical role in climate data collection. Orbiting Earth at high speeds, the <a href="https://www.earth.com/news/the-iss-is-contaminated-with-a-disturbing-amount-of-harmful-chemicals/" target="_blank" rel="noreferrer noopener">ISS</a> effectively performs regular flybys of nearly the entire planet. </p>



<p>This exceptional position allows its suite of instruments to continuously gather information from various locations, both day and night. The data collected by the ISS is proving invaluable in furthering our understanding of climate change and its effects.</p>



<h2 class="wp-block-heading" id="h-iss-climate-toolkit">ISS climate toolkit</h2>



<p>Let's explore some of ISS's instruments – it's like a space toolbox made to measure our changing planet:</p>



<h3 class="wp-block-heading" id="h-ecostress-the-plant-stress-detector-nbsp">ECOSTRESS: The plant stress-detector&nbsp;</h3>



<p>The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) operates similarly to a giant thermometer, but instead of measuring air temperature, it measures the temperature of plants themselves. </p>



<p>This allows scientists to identify areas where vegetation is facing stress due to excessive heat or insufficient water. This information is crucial for understanding how <a href="https://www.earth.com/news/nasa-initiates-ambitious-plan-to-bring-iss-back-to-earth/" target="_blank" rel="noreferrer noopener">climate</a> change impacts vital ecosystems like rainforests.</p>



<p>Climate change presents a complex global challenge. ECOSTRESS enables scientists to directly observe how ecosystems are responding to these ongoing changes.</p>



<h2 class="wp-block-heading" id="h-tsis-keeping-an-eye-on-the-sun-nbsp">TSIS: Keeping an eye on the sun&nbsp;</h2>



<p>The Sun acts as Earth's primary energy source, constantly bathing our planet in radiation. Even minor fluctuations in this energy output can have significant consequences for our climate. The Total and Spectral Solar Irradiance Sensor (TSIS) meticulously tracks the Sun's energy emissions. </p>



<p>This instrument functions like a highly precise monitor, continuously measuring the total amount of solar energy reaching Earth (Total Solar Irradiance) and the distribution of that energy across various wavelengths (Spectral Solar Irradiance). </p>



<p>By meticulously monitoring these values, scientists can gain valuable insights into how changes in solar activity might influence Earth's climate system.</p>



<h3 class="wp-block-heading" id="h-gedi-forests-in-focus-nbsp">GEDI: Forests in focus&nbsp;</h3>



<p>Forests play a critical role in maintaining a healthy climate for our planet. They act as massive carbon sinks, absorbing significant quantities of carbon dioxide, a major greenhouse gas. </p>



<p>The Global Ecosystem Dynamics Investigation (GEDI) utilizes cutting-edge laser technology to create incredibly detailed three-dimensional maps of Earth's forests. This advanced technology allows scientists to precisely measure various forest characteristics, including the total volume of vegetation and the overall distribution of trees across a landscape. </p>



<p>This information is invaluable for tracking the amount of carbon stored within forests. This helps scientists understand how these vital ecosystems are changing in response to climate pressures. By monitoring these changes, we can develop more effective strategies for protecting and managing our precious forests.</p>



<h3 class="wp-block-heading" id="h-emit-unmasking-methane-nbsp">EMIT: Unmasking methane&nbsp;</h3>



<p>Methane, while less abundant than carbon dioxide, is a far more potent greenhouse gas, significantly contributing to global warming. The Earth Surface Mineral Dust Source Investigation (EMIT) instrument possesses the remarkable ability to detect and pinpoint methane leaks from space. </p>



<p>This technological breakthrough is revolutionizing how we track and identify methane emission sources. The pinpoint accuracy that EMIT provides allows us to locate the sources of methane release, enabling targeted efforts to limit the impact of these emissions. </p>



<p>EMIT's technology represents a significant leap forward in our ability to locate methane sources and take the necessary steps to mitigate these emissions worldwide.</p>



<h3 class="wp-block-heading" id="h-oco-3-carbon-dioxide-detective-nbsp">OCO-3: Carbon dioxide detective&nbsp;</h3>



<p><a href="https://www.earth.com/video/iss-rapidscat-monitoring-earth-from-the-space-station/" target="_blank" rel="noreferrer noopener">ISS</a>'s Orbiting Carbon Observatory-3 (OCO-3) instrument is specifically designed to track carbon dioxide, a major driver of climate change. OCO-3 operates with exceptional precision, continuously monitoring and measuring the global distribution of atmospheric carbon dioxide. </p>



<p>This detailed information functions like a powerful magnifying glass, allowing scientists to pinpoint areas with particularly high concentrations of carbon dioxide. This newfound ability to visualize and track these "hotspots" of carbon dioxide emissions is proving invaluable in supporting international efforts to reduce greenhouse gas emissions. </p>



<p>By identifying specific emission sources, OCO-3 data empowers nations to develop more targeted strategies for curbing carbon dioxide pollution.</p>



<h3 class="wp-block-heading" id="h-sage-iii-iss-monitoring-the-atmosphere-s-layers-nbsp">SAGE III-ISS: Monitoring the atmosphere's layers&nbsp;</h3>



<p>Our planet's atmosphere acts as a protective shield, safeguarding us from harmful solar radiation and regulating Earth's temperature. </p>



<p>To better understand how human activities and natural phenomena affect this vital shield, the Stratospheric Aerosol and Gas Experiment III-ISS (SAGE III-<a href="https://www.earth.com/video/iss-rapidscat-starts-measuring-earth-wind/" target="_blank" rel="noreferrer noopener">ISS</a>) meticulously analyzes the intricate layers of Earth's atmosphere. </p>



<p>This instrument measures the concentration and distribution of various gases and tiny particles, known as aerosols, within each atmospheric layer. By monitoring these components, scientists gain valuable insights into how factors like pollutants impact the composition of the atmosphere. </p>



<p>The data collected by SAGE III-ISS plays a crucial role in improving the accuracy of climate models. These models rely on precise information about atmospheric composition and behavior to effectively simulate future climate scenarios. </p>



<p>With the data provided by SAGE III-ISS, scientists can refine these models, leading to more accurate predictions and a deeper understanding of the complex interactions within our planet's climate system.</p>



<h2 class="wp-block-heading" id="h-the-iss-is-essential-in-the-fight-against-climate-change">The ISS is essential in the fight against climate change </h2>



<p>As evident, the ISS plays a far more active role than simply observing Earth from afar. It serves as a vital platform for gathering the comprehensive climate data that scientists urgently need to address climate change. </p>



<p>By analyzing <a href="https://www.earth.com/news/nasa-initiates-ambitious-plan-to-bring-iss-back-to-earth/" target="_blank" rel="noreferrer noopener">ISS's</a> rich data set, scientists are equipped to develop innovative solutions for mitigating the effects of our warming planet.</p>

Data from the ISS helps us monitor climate change

Did you know that the very space station orbiting miles...

<p>Wildfires in Siberia are a global concern, as their increasing frequency is predicted to impact the climate, <a href="https://www.earth.com/news/twenty-years-of-air-quality-improvement-erased-by-wildfires/" target="_blank" rel="noreferrer noopener">air quality</a>, health, and economies far beyond their immediate vicinity. A new study highlights the far-reaching consequences of these natural disasters.</p>



<p>Researchers from <a href="https://www.hokudai.ac.jp/" target="_blank" rel="noreferrer noopener">Hokkaido University</a>, the <a href="https://www.u-tokyo.ac.jp/ja/index.html" target="_blank" rel="noreferrer noopener">University of Tokyo</a>, and <a href="https://www.kyushu-u.ac.jp/en/" target="_blank" rel="noreferrer noopener">Kyushu University</a> used advanced global climate models to analyze the potential impacts of wildfires in Siberia, and the results paint a striking picture. </p>



<p>The experts utilized the MIROC5 - a sophisticated modeling system - along with other predictive tools to actively simulate the broader effects of Siberian fires under current and future <a href="https://www.earth.com/news/wildfire-impacts-are-evolving-due-to-climate-change-but-in-what-ways/" target="_blank" rel="noreferrer noopener">climate</a> scenarios.</p>



<h2 class="wp-block-heading" id="h-climate-s-unexpected-response">Climate's unexpected response</h2>



<p>The simulations revealed that the increased intensity of wildfires in Siberia could lead to significant atmospheric changes, notably a cooling effect across the northern hemisphere. This phenomenon is largely due to the aerosols, or tiny air pollution particles, emitted by the fires which can reflect sunlight away from the earth's surface. </p>



<p>Professor Teppei Yasunari, a key member of the research team, explained: "Our modeling reveals a cooling effect broadly across the northern hemisphere and worsened air quality in extensive downwind regions."</p>



<h2 class="wp-block-heading" id="h-health-implications-of-wildfires-in-siberia">Health implications of wildfires in Siberia </h2>



<p>The aerosols released during these wildfires not only affect the climate but also degrade air quality, leading to serious <a href="https://www.earth.com/news/wildfire-smoke-is-an-underestimated-threat-to-public-health/" target="_blank" rel="noreferrer noopener">health</a> implications.</p>



<p>The researchers predict a dramatic increase in air pollution, especially under the most extreme wildfire scenarios. This pollution impacts not only Siberia but also vast areas of East Asia, which lie downwind from these fires.</p>



<p>The degraded air quality may cause an increase in premature deaths, respiratory problems, and other health issues. This could translate into health-related costs that potentially reach up to 10 billion US dollars annually.</p>



<p>"Our results suggest that increased efforts are needed to limit the effects of the <a href="https://www.earth.com/image/wildfires-in-siberia-2/" target="_blank" rel="noreferrer noopener">Siberian wildfires</a> somehow to prevent excess deaths, respiratory and other illnesses, and economic losses because it is hard to prevent the occurrence of Siberian wildfires in such large areas," said Professor Yasunari.</p>



<h2 class="wp-block-heading" id="h-economic-costs-of-siberia-wildfires">Economic costs of Siberia wildfires</h2>



<p>Beyond health, the economic impacts are also profound. The study suggests that the direct costs associated with increased mortality due to air pollution are substantial. </p>



<p>Additionally, the indirect costs, such as loss of productivity due to illness and reduced educational opportunities, could significantly amplify these figures.</p>



<p>The findings underscore the necessity for more refined models to better quantify and mitigate these impacts. </p>



<p>"Our findings send a critical message about the broad effect of increased particulate matter due to massive wildfires in the atmosphere on climate and air quality, which will become ever more significant as the worldwide changes due to global warming proceed," said Professor Yasunari.</p>



<p>The research not only sheds light on the urgent need for global attention to Siberian wildfires but also calls for international cooperation in <a href="https://www.earth.com/news/fire-suppression-methods-increase-the-severity-of-wildfires/" target="_blank" rel="noreferrer noopener">fire management</a> and mitigation strategies to safeguard public health and protect the global economy from the potentially devastating effects of these increasing natural disasters. </p>



<p>To better understand and address the extensive consequences of wildfires on a global scale, the time to act is now.</p>



<h2 class="wp-block-heading">More about wildfires in Siberia&nbsp;</h2>



<p>Siberian wildfires typically occur during the region's dry and warm summer months. Siberia, known for its vast and remote forested areas, is particularly vulnerable to wildfires due to a combination of factors, including rising temperatures and dry conditions, which are often linked to climate change.</p>



<h3 class="wp-block-heading">Far-reaching impacts&nbsp;</h3>



<p>The impact of Siberian wildfires is extensive, affecting not only local flora and fauna but also contributing to air quality issues over a wide area, including neighboring countries.&nbsp;</p>



<p>The smoke from these fires can travel thousands of kilometers, affecting atmospheric conditions and climate patterns on a global scale. For instance, the dense smoke can reduce visibility and impact air quality, posing health risks to populations even in distant areas.</p>



<h3 class="wp-block-heading" id="h-fire-management">Fire management</h3>



<p>Efforts to combat and manage these fires are challenged by the sheer scale and remoteness of the affected areas. The Russian government and local authorities often struggle with limited resources and logistical difficulties in accessing these regions.&nbsp;</p>



<h3 class="wp-block-heading">Environmental threat</h3>



<p>Moreover, the frequency and intensity of these fires have been increasing, prompting concerns about long-term environmental damage, including the release of stored carbon from Siberian peatlands, which exacerbates global warming.</p>



<p>The study is published in the journal <em><em><a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023EF004129" target="_blank" rel="noreferrer noopener">Earth's Future</a></em></em>.</p>

<p>Working memory plays a pivotal role in our day-to-day functions. It's an essential brain skill that helps us manage and process information while engaging in activities, without losing <a href="https://www.earth.com/news/how-does-the-brain-focus-with-so-many-distractions/" target="_blank" rel="noreferrer noopener">focus</a>. </p>



<p>For instance, working memory allows us to remember to buy more dishwasher soap while we're busy loading the dishwasher and to keep track of other future necessities.</p>



<p>Researchers have long understood the significant variability in working memory across individuals but have struggled to pinpoint the reasons behind these differences. </p>



<p>Taking an innovative approach to studying this dilemma, researchers at the <a href="https://www.uta.edu/" target="_blank" rel="noreferrer noopener">University of Texas at Arlington</a>, including Matthew Robinson and Lauren Garner, conducted an experiment that examined whether pupil dilation could be a reliable indicator of working memory capacity.</p>



<h2 class="wp-block-heading" id="h-understanding-pupil-dilation-and-working-memory">Understanding pupil dilation and working memory</h2>



<p>In a recent study, it was discovered that pupil size could tell us more than just how much light is entering the eye. </p>



<p>Typically, pupils dilate in low-light conditions to improve vision. However, this study revealed that pupils also dilate in response to <a href="https://www.earth.com/news/cognitive-stimulation-at-work-helps-prevent-memory-problems/" target="_blank" rel="noreferrer noopener">cognitive</a> tasks requiring concentration.</p>



<p>The study involved 179 undergraduate students who underwent a series of working memory tests. While they attempted these tasks, an eye-tracker, similar to devices used during routine eye exams, continuously measured their pupil dilation. The findings were quite revealing. </p>



<p>"We found that people who more intensely and consistently paid attention, as evidenced by greater <a href="https://www.earth.com/news/traumatic-experiences-can-be-detected-in-the-eyes/" target="_blank" rel="noreferrer noopener">pupil dilation</a>, performed better on memory tasks," explained Robinson.</p>



<p>"The highest-performing participants not only had larger overall pupil dilations but were also more discerning about the information they needed to remember," he added.</p>



<h2 class="wp-block-heading" id="h-how-pupil-dilation-correlates-to-performance">How pupil dilation correlates to performance</h2>



<p>The correlation between pupil size and <a href="https://www.earth.com/news/understanding-how-students-learn-is-key-to-helping-them-succeed/" target="_blank" rel="noreferrer noopener">task performance</a> could have broader implications. </p>



<p>For instance, Matthew Robison noted that, "The lowest performers on the tasks showed less pupil dilation. For the highest-performing participants, their pupil dilations were both larger overall and the individuals were more discerning about the information they were asked to recall."</p>



<p>This research highlights a fascinating aspect of how our bodies respond to mental exertion and could lead to more personalized approaches in educational and professional settings to enhance <a href="https://www.earth.com/news/stress-smaller-brain-size/" target="_blank" rel="noreferrer noopener">cognitive performance</a>.</p>



<p>The study, published in the peer-reviewed journal <em>Attention, Perception &amp; Psychophysics</em>, provides valuable insights into the physiological underpinnings of working memory. </p>



<p>"This is exciting research because it adds another valuable piece of the puzzle to our understanding of why working <a href="https://www.earth.com/news/daily-multivitamins-slow-cognitive-aging-and-improve-memory/" target="_blank" rel="noreferrer noopener">memory</a> varies between individuals," Robison concluded.</p>



<h2 class="wp-block-heading">Exploring the intricacies of working memory</h2>



<p>Working memory enables us to hold and manipulate information in our minds for short periods, allowing us to perform complex tasks, solve problems, and make decisions. Without working memory, we would struggle to navigate the world around us effectively.</p>



<h3 class="wp-block-heading">Components</h3>



<h4 class="wp-block-heading" id="h-the-phonological-loop">The phonological loop</h4>



<p>This component handles auditory information, such as speech and sound.</p>



<h4 class="wp-block-heading" id="h-the-visuospatial-sketchpad">The visuospatial sketchpad</h4>



<p>This component processes visual and <a href="https://www.earth.com/news/blinking-plays-crucial-role-vision-human-perception/" target="_blank" rel="noreferrer noopener">spatial information</a>, such as images and locations.</p>



<h4 class="wp-block-heading" id="h-the-central-executive">The central executive</h4>



<p>This component acts as a control center, allocating attention and coordinating the activities of the other components.</p>



<h4 class="wp-block-heading" id="h-the-episodic-buffer">The episodic buffer</h4>



<p>This component integrates information from the other components and <a href="https://www.earth.com/news/wasabi-linked-to-substantial-boost-in-memory/" target="_blank" rel="noreferrer noopener">long-term memory</a>, creating a unified representation.</p>



<h3 class="wp-block-heading">Capacity</h3>



<p>Working memory has a limited capacity, typically allowing us to hold and manipulate between three and seven items at a time. This capacity varies among individuals and can be influenced by factors such as age, training, and cognitive impairments. </p>



<p>Researchers have developed various tests and tasks to measure working memory capacity, such as the n-back task and the complex span task.</p>



<h3 class="wp-block-heading">Importance in everyday life</h3>



<p>Working memory plays a vital role in numerous everyday activities, such as:</p>



<ul>
<li>Following instructions and directions<br></li>



<li>Engaging in conversations and maintaining the flow of dialogue<br></li>



<li>Reading comprehension and language processing<br></li>



<li>Performing mental calculations and problem-solving<br></li>



<li>Multitasking and switching between different tasks</li>
</ul>



<p>Deficits in working memory can lead to difficulties in these areas, impacting an individual's academic performance, work efficiency, and social interactions.</p>



<h3 class="wp-block-heading">Enhancement strategies</h3>



<p>While working memory capacity is largely determined by genetic factors, research suggests that certain strategies and interventions can help improve its efficiency:</p>



<ul>
<li><strong>Chunking</strong>: Grouping information into meaningful units to reduce the number of items to be remembered.</li>
</ul>



<ul>
<li><strong>Rehearsal</strong>: Repeating information mentally or aloud to maintain it in working memory.</li>
</ul>



<ul>
<li><strong>Visualization</strong>: Creating mental images or diagrams to represent information visually.</li>
</ul>



<ul>
<li><strong>Mindfulness and meditation</strong>: Practicing <a href="https://www.earth.com/news/mindfulness-protects-against-work-stress-burnout/" target="_blank" rel="noreferrer noopener">mindfulness</a> and meditation techniques to improve focus and attention.</li>
</ul>



<ul>
<li><strong>Cognitive training</strong>: Engaging in targeted exercises and activities designed to challenge and strengthen working memory</li>
</ul>



<p>By understanding the intricacies of working memory and employing these strategies, individuals can optimize their cognitive performance and enhance their ability to navigate the demands of daily life.</p>



<h2 class="wp-block-heading" id="h-pupil-dilation-working-memory-and-future-implications">Pupil dilation, working memory, and future implications</h2>



<p>In summary, this study has revealed a fascinating connection between pupil dilation and working memory performance. By measuring participants' pupils during cognitive tasks, the researchers discovered that individuals with greater pupil dilation and sensitivity consistently outperformed those with less dilation. </p>



<p>This finding enhances our understanding of the factors influencing working memory variation and paves the way for future research into the neural mechanisms underlying this critical cognitive skill. </p>



<p>As scientists continue to explore the complexities of the brain's executive functions, studies like this one bring us closer to developing targeted interventions and strategies to support individuals struggling with working memory, ultimately unlocking the full potential of the human mind.</p>

Pupils enlarge when the brain's working memory is focused on a task

Working memory plays a pivotal role in our day-to-day functions....

<p>Researchers at the <a href="https://illinois.edu/">University of Illinois Urbana-Champaign</a> have recently reported that both public parks and private backyards play a vital role in supporting bird diversity in urban environments. </p>



<p>"Greenspaces are increasingly valued for supporting biodiversity in urbanized landscapes. Previous research efforts have emphasized the importance of public land such as parks and nature preserves for biodiversity, yet private yards in residential neighborhoods also have great potential for species conservation," wrote the researchers. </p>



<p>By studying two closely situated cities in Illinois with contrasting development histories and green space management, the experts discovered that these spaces are crucial for different bird species during varying seasons.</p>



<h2 class="wp-block-heading" id="h-urban-bird-populations">Urban bird populations</h2>



<p>The researchers monitored <a href="https://www.earth.com/news/bird-populations-are-declining-worldwide/" target="_blank" rel="noreferrer noopener">bird populations</a> across 39 public parks and 41 private yards in Urbana and Champaign - cities with distinct urban characteristics and historical development. </p>



<p>Urbana, with a history dating back to 1822, boasts extensive green spaces nurtured within an ancient hardwood forest. By contrast, Champaign was developed in the mid-1800s along a railway - with a focus on human recreation in its smaller parks.</p>



<h2 class="wp-block-heading" id="h-seasonal-variations-in-urban-bird-diversity">Seasonal variations in urban bird diversity </h2>



<p>The analysis revealed significant seasonal shifts in bird <a href="https://www.earth.com/news/u-s-bird-diversity-puzzling-geographical-differences-identified/" target="_blank" rel="noreferrer noopener">diversity</a> between the two cities. During summer, Urbana's richer vegetation and cooler green spaces attracted a broader variety of birds, including species like the belted kingfisher and scarlet tanager. </p>



<p>Conversely, in winter, Urbana's parks and yards continued to support diverse communities, including the winter wren and yellow-bellied sapsucker.</p>



<h2 class="wp-block-heading" id="h-impact-of-urban-management-on-bird-diversity">Impact of urban management on bird diversity</h2>



<p>Pollock pointed out the significant effects of active management in urban green spaces. "In places where there’s been active management to try to increase plant diversity and get some native plant cover back, it has had a big impact on the <a href="https://www.earth.com/news/as-urban-heat-continues-to-rise-birds-are-moving-away/" target="_blank" rel="noreferrer noopener">bird</a> communities," he explained. </p>



<p>Urbana's parks, with their focus on conservation and habitat restoration, were especially beneficial for rare and specialist bird species.</p>



<h2 class="wp-block-heading" id="h-practical-actions-for-residents">Practical actions for residents</h2>



<p>The study also suggests practical ways for residents to enhance bird diversity in their own backyards. Carena Van Riper, a collaborator on the project, encouraged simple yet effective actions. </p>



<p>"Perhaps this will allow people to see that there are small but important behaviors that will influence birds and increase bird diversity," noted Van Riper. </p>



<p>Among the recommendations were installing bird feeders (especially during winter), planting native vegetation, and setting up bird baths.</p>



<h2 class="wp-block-heading" id="h-urban-greenery-a-blueprint-for-biodiversity">Urban greenery: A blueprint for biodiversity </h2>



<p>This comprehensive study underscores the interconnectedness of urban management and biodiversity. It offers a fresh perspective on how both public and private green spaces play integral roles in supporting urban wildlife. </p>



<p>As cities continue to grow, understanding and implementing strategies that facilitate coexistence with nature becomes even more crucial. </p>



<p>The insights from Urbana and Champaign can serve as a guide for other <a href="https://www.earth.com/news/green-spaces-shape-bird-characteristics-in-urban-areas/" target="_blank" rel="noreferrer noopener">urban areas</a> aiming to enhance biodiversity and sustainability within their confines.</p>



<h2 class="wp-block-heading">What influences urban bird diversity?</h2>



<p>Urban bird diversity is influenced by a variety of factors, each playing a role in how well birds can adapt and thrive in city environments. Key factors include:</p>



<h3 class="wp-block-heading">Green spaces</h3>



<p>The presence and quality of green spaces such as parks, gardens, and green roofs are crucial. These areas provide essential resources like food, nesting sites, and safe havens from urban threats.</p>



<h3 class="wp-block-heading">Water bodies</h3>



<p>Rivers, lakes, and ponds in urban settings attract waterfowl and other species that rely on aquatic habitats for feeding and breeding.</p>



<h3 class="wp-block-heading">Food availability</h3>



<p>The accessibility of natural food sources, supplemented by bird feeders, significantly impacts which species are able to sustain populations in urban areas.</p>



<h3 class="wp-block-heading">Building designs</h3>



<p>The architecture of a city influences bird diversity. Features like reflective glass can cause bird collisions, whereas features like ledges and nooks might offer nesting spots.</p>



<h3 class="wp-block-heading">Pollution</h3>



<p>Air and noise pollution can deter birds from settling in urban areas. Pollution can also affect the health of the habitats birds rely on.</p>



<h3 class="wp-block-heading">Human interaction</h3>



<p>The level and nature of human activity and disturbance - ranging from benign presence to active conservation efforts - play a big role. Quieter, less disturbed areas tend to support more diverse bird populations.</p>



<h3 class="wp-block-heading">Climate</h3>



<p>Urban microclimates, influenced by the heat island effect where cities are warmer than surrounding areas, can affect which species are likely to thrive or decline in urban settings.</p>



<p>The study is published in the journal <em><a href="https://www.sciencedirect.com/science/article/pii/S0169204624000598?via%3Dihub" target="_blank" rel="noreferrer noopener">Landscape and Urban Planning</a></em>.</p>

How urban spaces support bird diversity

Researchers at the University of Illinois Urbana-Champaign have recently reported...

<p>Water evaporation is a fundamental process that occurs all around us, from the surfaces of oceans and lakes to the <a href="https://www.earth.com/news/scientists-are-unraveling-the-mysteries-of-fog-formation/" target="_blank" rel="noreferrer noopener">burning off of fog</a> in the morning light from the sun. </p>



<p>For centuries, humans have observed and utilized this phenomenon, assuming that heat was the sole cause of <a href="https://www.earth.com/news/new-technology-can-purify-water-as-it-is-collected-from-fog/" target="_blank" rel="noreferrer noopener">evaporation</a>. However, a truly groundbreaking discovery by a team of scientists has revealed that there is more to evaporation than meets the eye.</p>



<h2 class="wp-block-heading" id="h-photomolecular-effect-how-light-breaks-water-molecules">Photomolecular effect: How light breaks water molecules</h2>



<p>In a series of meticulous experiments, a team led by Gang Chen, the Carl Richard Soderberg Professor of Power Engineering at <a href="https://www.mit.edu" target="_blank" rel="noreferrer noopener">MIT</a>, along with postdocs Guangxin Lv and Yaodong Tu, and graduate student James Zhang, has demonstrated that light can also cause water to <a href="https://www.earth.com/news/transforming-drinking-bird-toy-into-power-generator-electricity/" target="_blank" rel="noreferrer noopener">evaporate</a>, even in the absence of heat. </p>



<p>Their findings, published in the journal <em>PNAS</em>, suggest that this effect, which they have named the photomolecular effect, could have far-reaching implications in various fields, from climate science to industrial applications.</p>



<p>The researchers have named this phenomenon the photomolecular effect, drawing an analogy with the <a href="https://www.earth.com/news/quantum-ping-pong-game-played-by-two-atoms-controlling-photons/" target="_blank" rel="noreferrer noopener">photoelectric effect</a> discovered by Heinrich Hertz in 1887 and later explained by Albert Einstein in 1905. </p>



<p>Just as the photoelectric effect demonstrates that photons of light can liberate electrons from atoms in a material, the photomolecular effect shows that photons can also liberate entire molecules from a liquid surface.</p>



<h2 class="wp-block-heading">Solving an 80-year-old mystery in climate science</h2>



<p>This discovery may hold the key to solving an 80-year-old mystery in <a href="https://www.earth.com/news/global-temperature-increase-2023-blew-past-all-climate-models/" target="_blank" rel="noreferrer noopener">climate science</a>, which has puzzled scientists for decades. Measurements of cloud absorption of sunlight have often shown discrepancies, with clouds absorbing more sunlight than conventional physics dictates possible.</p>



<p>"Those experiments are based on satellite data and flight data. They fly an airplane on top of and below the clouds, and there are also data based on the ocean temperature and radiation balance. And they all conclude that there is more <a href="https://www.earth.com/news/sci-fi-inspired-scenarios-illustrate-our-impact-on-earths-water-cycle/" target="_blank" rel="noreferrer noopener">absorption by clouds</a> than theory could calculate," Gang Chen explains. </p>



<p>"However, due to the complexity of clouds and the difficulties of making such measurements, researchers have been debating whether such discrepancies are real or not. And what we discovered suggests that hey, there's another mechanism for <a href="https://www.earth.com/news/microplastics-found-in-clouds-may-be-affecting-the-weather/" target="_blank" rel="noreferrer noopener">cloud absorption</a>, which was not accounted for, and this mechanism might explain the discrepancies," Chen continued.</p>



<h2 class="wp-block-heading" id="h-rigorous-testing-and-evidence">Rigorous testing and evidence</h2>



<p>Due to the unexpected <a href="https://www.earth.com/news/light-can-drive-water-evaporation-without-heat/" target="_blank" rel="noreferrer noopener">nature of the effect</a>, the research team conducted 14 different kinds of tests and measurements to establish that water was indeed evaporating due to light alone, not heat. </p>



<p>One key indicator, consistently observed in four different experiments under varying conditions, was the cooling and leveling off of air temperature above the water's surface as evaporation began under visible light. This finding suggests that thermal energy was not the driving force behind the effect.</p>



<p>Lv, one of the postdocs involved in the study, highlights that among the many lines of evidence, "the flat region in the air-side temperature distribution above hot water will be the easiest for people to reproduce." This temperature profile "is a signature" that demonstrates the effect clearly, he says.</p>



<p>Zhang, the graduate student on the team, adds: "It is quite hard to explain how this kind of flat temperature profile comes about without invoking some other mechanism" beyond the accepted theories of thermal evaporation. </p>



<p>According to Zhang, "It ties together what a whole lot of people are reporting in their <a href="https://www.earth.com/news/cheap-and-drinkable-water-from-desalination-is-finally-a-reality/" target="_blank" rel="noreferrer noopener">solar desalination</a> devices," which again show evaporation rates that cannot be explained by the thermal input.</p>



<h2 class="wp-block-heading" id="h-substantial-impact-four-times-the-thermal-limit">Substantial impact: Four times the thermal limit</h2>



<p>The photomolecular effect can have a substantial impact on evaporation rates. Under the optimum conditions of color, angle, and polarization, Lv says, "the evaporation rate is four times the thermal limit."</p>



<p>"I think this has a lot of applications," Chen says. "We're exploring all these different directions. And of course, it also affects the basic science, like the effects of clouds on climate, because clouds are the most uncertain aspect of climate models."</p>



<p>Since the publication of the <a href="https://news.mit.edu/2023/surprising-finding-light-makes-water-evaporate-without-heat-1031" target="_blank" rel="noreferrer noopener">first paper</a> on this topic, the team has been approached by companies hoping to harness the effect for various applications, including evaporating syrup and drying paper in a paper mill. </p>



<p>Chen believes that the likeliest first applications will come in the areas of <a href="https://www.earth.com/news/converting-seawater-into-drinkable-water-is-now-more-sustainable/" target="_blank" rel="noreferrer noopener">solar desalinization</a> systems or other industrial drying processes. "Drying consumes 20 percent of all industrial energy usage," he points out.</p>



<h2 class="wp-block-heading" id="h-new-frontier-in-light-water-interactions-and-evaporation">New frontier in light-water interactions and evaporation</h2>



<p>As the photomolecular effect is a new and unexpected phenomenon, Chen emphasizes that "this phenomenon should be very general, and our experiment is really just the beginning." </p>



<p>The experiments needed to demonstrate and quantify the effect are very time-consuming, and there are many variables to explore, from understanding water itself to extending the research to other materials, liquids, and even solids.</p>



<p>"The finding of evaporation caused by light instead of heat provides new disruptive knowledge of light-water interaction. It could help us gain new understanding of how sunlight interacts with cloud, fog, oceans, and other natural water bodies to affect weather and climate," enthused Xiulin Ruan, professor of mechanical engineering at <a href="https://www.purdue.edu" target="_blank" rel="noreferrer noopener">Purdue University</a>, who was not involved in the study.</p>



<p>"It has significant potential practical applications such as high-performance water desalination driven by solar energy. This research is among the rare group of truly revolutionary discoveries which are not widely accepted by the community right away but take time, sometimes a long time, to be confirmed," Ruan concluded.</p>



<h2 class="wp-block-heading" id="h-how-the-photomolecular-effect-could-transform-our-world">How the photomolecular effect could transform our world</h2>



<p>In summary, the photomolecular effect represents a paradigm shift in our understanding of water evaporation and light-water interaction. </p>



<p>This truly groundbreaking discovery by Gang Chen and his team at MIT challenges long-held assumptions and opens up a wealth of possibilities for future research and applications. </p>



<p>As scientists continue to explore the variables and implications of this phenomenon, we can anticipate a new era of innovation in fields ranging from climate science to industrial processes. </p>



<p>The photomolecular effect reminds us that even the most fundamental and seemingly well-understood processes in nature can still hold surprises, and that the pursuit of scientific knowledge is an ongoing journey of discovery and wonder.</p>



<p>The full study was published in the journal <em><a href="https://www.pnas.org/doi/10.1073/pnas.2320844121" target="_blank" rel="noreferrer noopener">Proceedings of the National Academy of Sciences</a></em>.</p>

<p>Their research introduces a <a href="https://www.nature.com/articles/s41592-022-01426-1" target="_blank" rel="noreferrer noopener">new protocol</a> for using SLEAP to analyze plant root phenotypes, such as depth, width, and mass.</p>



<p>"This collaboration is truly a testament to what makes Salk science so special and impactful," says Pereira. "We're not just 'borrowing' from different disciplines -- we're really putting them on equal footing in order to create something greater than the sum of its parts."</p>



<h2 class="wp-block-heading" id="h-streamlining-plant-analysis-with-ai">Streamlining plant analysis with AI</h2>



<p>Prior to SLEAP, analyzing plant and animal characteristics was a labor-intensive process that slowed scientific progress. </p>



<p>Researchers had to manually flag parts of images frame-by-frame, part-by-part, and pixel-by-pixel before older AI models could process the data.</p>



<p>SLEAP's unique combination of computer vision and <a href="https://www.earth.com/news/machine-learning-could-help-save-mangrove-forests/" target="_blank" rel="noreferrer noopener">deep learning</a> allows researchers to skip this intermediary step, jumping straight from image input to defined plant features. </p>



<p>This approach significantly reduces analysis time and human error while emphasizing accessibility and ease of use.</p>



<h2 class="wp-block-heading" id="h-sleap-roots-digging-deep-into-plant-biology">sleap-roots: Digging deep into plant biology</h2>



<p>The Salk team developed sleap-roots, a downloadable toolkit for SLEAP that enables the software to process biological traits of root systems, such as depth, mass, and angle of growth. </p>



<p>The toolkit, available as open-source software, was tested on various plants, including soybeans, rice, canola, and <em><a href="https://www.earth.com/news/scientists-capture-plant-communication-on-video/" target="_blank" rel="noreferrer noopener">Arabidopsis thaliana</a></em>.</p>



<p>"We created a robust protocol validated in multiple plant types that cuts down on analysis time and human error, while emphasizing accessibility and ease-of-use -- and it required no changes to the actual SLEAP software," says Elizabeth Berrigan, a bioinformatics analyst in Busch's lab.</p>



<h2 class="wp-block-heading" id="h-deciphering-the-secrets-of-climate-saving-plants">Deciphering the secrets of climate-saving plants</h2>



<p>By connecting phenotypic data, such as a plant's <a href="https://www.earth.com/news/measuring-plant-root-health-scanning-leaves-xray-device/" target="_blank" rel="noreferrer noopener">deep root system</a>, with genotype data obtained through genome sequencing efforts, researchers can identify the genes responsible for creating desirable traits. </p>



<p>This step is crucial in Salk's mission to create plants with AI that hold on to more carbon for longer periods, as these plants will require root systems designed to be deeper and more robust.</p>



<p>"We have already been able to create the most extensive catalogue of plant root system phenotypes to date, which is really accelerating our research to create carbon-capturing plants that fight climate change," says Busch, the Hess Chair in <a href="https://pbio.salk.edu/" target="_blank" rel="noreferrer noopener">Plant Science at Salk</a>. </p>



<p>"SLEAP has been so easy to apply and use, thanks to Talmo's professional software design, and it's going to be an indispensable tool in my lab moving forward," Busch concluded.</p>



<h2 class="wp-block-heading" id="h-understanding-the-hidden-world-of-plant-root-systems">Understanding the hidden world of plant root systems</h2>



<p>To further clarify, plant root systems are intricate networks of roots that play a crucial role in anchoring plants to the soil, absorbing water and nutrients, and storing essential compounds. </p>



<p>There are <a href="https://www.earth.com/news/maize-plant-genetics-shape-root-health-and-growth/" target="_blank" rel="noreferrer noopener">two main types of root systems</a> exist in plants: taproot systems and fibrous root systems. </p>



<ul>
<li>Taproot systems feature a single, dominant root that grows vertically downward, with smaller lateral roots branching off from it. </li>
</ul>



<ul>
<li>Fibrous root systems, on the other hand, consist of numerous small roots that grow outward from the base of the plant, forming a dense network.</li>
</ul>



<h3 class="wp-block-heading">Functions of root systems</h3>



<p><a href="https://www.earth.com/news/plant-roots-follow-gravity/" target="_blank" rel="noreferrer noopener">Root systems</a> perform several critical functions for plants:</p>



<ul>
<li><strong>Anchoring:</strong> Roots secure plants to the soil, providing stability and preventing them from toppling over.</li>
</ul>



<ul>
<li><strong>Absorption:</strong> Fine root hairs absorb water and dissolved nutrients from the soil, which are then transported to the rest of the plant.</li>
</ul>



<ul>
<li><strong>Storage:</strong> Some plants, such as carrots and beets, use their roots to store carbohydrates and other essential compounds.</li>
</ul>



<h3 class="wp-block-heading">Factors influencing root growth</h3>



<p>Several factors influence the growth and development of plant root systems:</p>



<ul>
<li><strong>Soil type:</strong> Different soil types, such as sandy, loamy, or clay soils, affect root growth and distribution.</li>
</ul>



<ul>
<li><strong>Water availability:</strong> Plants adapt their root systems in response to water availability, with some species growing deeper roots to access water in times of drought.</li>
</ul>



<ul>
<li><strong>Nutrient availability:</strong> The presence or absence of essential nutrients in the soil can impact root growth and architecture.</li>
</ul>



<p>Healthy root systems are essential for overall plant health and productivity. <a href="https://www.earth.com/news/deep-rooted-crops-can-significantly-improve-soil-carbon-storage/" target="_blank" rel="noreferrer noopener">Well-developed roots</a> enable plants to efficiently absorb water and nutrients, leading to stronger growth and increased resilience to stresses such as drought or disease. </p>



<h2 class="wp-block-heading" id="h-ai-and-the-future-of-climate-saving-plants">AI and the future of climate-saving plants</h2>



<p>The accessibility and reproducibility of SLEAP and sleap-roots have the potential to revolutionize plant research worldwide. The Salk team has already begun discussions with NASA scientists hoping to utilize the tool to guide <a href="https://www.earth.com/news/reducing-air-pollution-could-greatly-boost-carbon-sequestration-by-plants/" target="_blank" rel="noreferrer noopener">carbon-sequestering plants</a> on Earth and to study plants in space.</p>



<p>In summary, the Salk Institute's pioneering research in plant-based carbon capture, powered by the innovative SLEAP software and sleap-roots toolkit, paves the way for a greener future. </p>



<p>As scientists continue to refine and expand these tools, they accelerate the development of climate-saving plants with optimized root systems capable of storing more carbon for longer periods. </p>



<p>The accessibility and reproducibility of SLEAP and sleap-roots invite researchers worldwide to join the fight against climate change, fostering global collaboration and innovation. </p>



<p>With the Harnessing Plants Initiative at the forefront, Salk scientists are rooting for change, digging deep into plant biology, and branching out to make a lasting impact on our planet's future.</p>

AI is creating new plants that can help fight climate change

By focusing on root systems, researchers aim to create new...

<p>Bioluminescence, the remarkable ability of organisms to generate light through chemical reactions, originated in marine invertebrates known as <a href="https://www.earth.com/news/some-corals-and-reefs-are-showing-surprising-resilience-as-global-waters-warm/" target="_blank" rel="noreferrer noopener">octocorals</a> at least 540 million years ago, according to a new study by researchers at the <a href="https://naturalhistory.si.edu/%C3%B9" target="_blank" rel="noreferrer noopener">Smithsonian’s National Museum of Natural History</a>. </p>



<p>These findings significantly predate previous records, which dated the earliest emergence of this luminous trait in animals to about 267 million years ago in ostracods, a type of small marine crustacean.</p>



<h2 class="wp-block-heading" id="h-evolutionary-history-of-bioluminescence-nbsp">Evolutionary history of bioluminescence&nbsp;</h2>



<p>This groundbreaking research not only revises the timeline of bioluminescence's evolutionary history but also opens new pathways to understanding why this ability developed.&nbsp;</p>



<p>“Nobody quite knows why it first evolved in animals,” said senior author Andrea Quattrini, the museum’s curator of corals. This mystery underscores the complexity and significance of bioluminescence, which has independently evolved at least 94 times across various species and plays crucial roles in behaviors such as <a href="https://www.earth.com/news/animals-are-losing-their-camouflage-under-modern-street-lights/%C3%B9" target="_blank" rel="noreferrer noopener">camouflage</a>, courtship, communication, and hunting.</p>



<h2 class="wp-block-heading" id="h-bioluminescent-group-of-corals-nbsp">Bioluminescent group of corals&nbsp;</h2>



<p>The focus of the study was on octocorals - an ancient and frequently bioluminescent group that includes soft corals, sea fans, and sea pens. Unlike hard corals, octocorals consist of tiny colonial polyps that secrete a soft framework as their habitat.&nbsp;</p>



<p>These organisms often exhibit bioluminescence when disturbed, although the exact reasons for this trait remain somewhat elusive.</p>



<p>To determine the origins of bioluminescence in octocorals, the researchers, including lead author Danielle DeLeo, a former postdoctoral fellow and museum research associate, analyzed an evolutionary tree of octocorals developed by Quattrini and Catherine McFadden of <a href="https://www.hmc.edu/" target="_blank" rel="noreferrer noopener">Harvey Mudd College</a> in 2022. </p>



<p>This tree, constructed using genetic data from 185 octocoral species, provided a detailed map of the evolutionary relationships within this group.</p>



<h2 class="wp-block-heading" id="h-bioluminescence-in-the-ancestors-of-current-octocorals">Bioluminescence in the ancestors of current octocorals</h2>



<p>By integrating two known-aged octocoral fossils into this group based on their physical features, the team was able to estimate the timeline of evolutionary splits within the octocoral lineage. They then mapped bioluminescent species onto this tree and applied statistical techniques for what is known as ancestral state reconstruction.&nbsp;</p>



<p>This analysis aimed to infer the likelihood of bioluminescence in the ancestors of current octocorals. “If we know these species of octocorals living today are bioluminescent, we can use statistics to infer whether their ancestors were highly probable to be bioluminescent or not,” Quattrini explained.</p>



<p>The results were striking: bioluminescence likely existed in the common ancestor of all octocorals around 540 million years ago, a significant advancement over the previous record held by bioluminescent ostracods. </p>



<p>This early emergence suggests that bioluminescence has been a key trait contributing to the evolutionary success and long-term survival of octocorals.</p>



<h2 class="wp-block-heading" id="h-mystery-of-bioluminescence-nbsp">Mystery of bioluminescence&nbsp;</h2>



<p>The findings also raise further questions about the specific uses of bioluminescence in octocorals, prompting DeLeo and her colleagues to plan additional research. They are developing a genetic test to determine the presence of luciferase, an enzyme crucial for bioluminescence, in octocorals.&nbsp;</p>



<p>This tool will help identify which of the over 3,000 living octocoral species still possess this luminescent capability and which have lost it, potentially shedding light on the ecological factors influencing this trait.</p>



<h2 class="wp-block-heading" id="h-fascinating-biological-trait-nbsp">Fascinating biological trait&nbsp;</h2>



<p>Beyond its scientific implications, the study provides essential evolutionary context for the conservation and management of octocorals, which are increasingly threatened by <a href="https://www.earth.com/news/massive-study-provides-answers-to-how-coral-reefs-can-survive-climate-change/" target="_blank" rel="noreferrer noopener">climate change</a> and human activities such as fishing, oil and gas extraction, and marine mineral mining. </p>



<p>The research is part of the museum’s Ocean Science Center's mission to enhance global understanding of oceanic processes and challenges.</p>



<p>As this study, published in the journal <a href="http://dx.doi.org/10.1098/rspb.2023.2626" target="_blank" rel="noreferrer noopener"><em>Proceedings of the Royal Academy of Sciences</em></a>, redefines the ancient origins of bioluminescence, while highlighting the need for further exploration into why such a fascinating biological trait evolved and its role in the survival and adaptation of marine organisms over millions of years.</p>



<h2 class="wp-block-heading" id="h-advantages-of-bioluminescence-in-animals">Advantages of bioluminescence in animals</h2>



<p>Bioluminescence offers several advantages in the natural world. Predominantly found in marine organisms, though also present in some terrestrial species, this fascinating <a href="https://www.earth.com/news/bioluminescent-gene-identified-that-makes-sea-pickles-glow/" target="_blank" rel="noreferrer noopener">biological trait</a> serves various ecological roles. </p>



<h3 class="wp-block-heading" id="h-luring-prey-nbsp">Luring prey&nbsp;</h3>



<p>For many deep-sea creatures, bioluminescence is crucial for attracting prey. The deep ocean is pitch dark, so any source of light is likely to draw attention. Organisms can use this to lure smaller creatures close enough to capture them.</p>



<h3 class="wp-block-heading" id="h-defense-mechanism-nbsp">Defense mechanism&nbsp;</h3>



<p>Moreover, bioluminescence is used for defense. Some species emit light to startle or distract <a href="https://www.earth.com/news/top-marine-predators-may-suffer-massive-habitat-loss-by-2100/" target="_blank" rel="noreferrer noopener">predators</a>, giving them a chance to escape. Others may use bioluminescence to camouflage themselves, blending in with light filtering down from the surface to erase their silhouette and confuse predators from below.</p>



<h3 class="wp-block-heading" id="h-reproduction-nbsp">Reproduction&nbsp;</h3>



<p>In addition to predation and defense, bioluminescence plays a role in reproduction. Certain species emit specific light patterns to attract mates, ensuring that they can find one another in the vast and dark depths of the oceans.</p>



<h3 class="wp-block-heading" id="h-communication">Communication</h3>



<p>The light can also serve as a form of communication among members of the same species, helping them signal their location, maintain group cohesion, or even warn others of dangers.</p>

Bioluminescence emerged in animals 540 million years ago

Bioluminescence, the remarkable ability of organisms to generate light through...

<p>Each day, roughly 43 million Americans indulge in at least one slice of <a href="https://www.earth.com/news/physics-perfect-pizza/" target="_blank" rel="noreferrer noopener">pizza</a>, contributing an impressive $47 billion annually to the U.S. economy. A significant portion of these pizzas arrives in corrugated cardboard boxes, posing a notable challenge for waste management due to their contamination with fats, oils, and greases (FOGs). Therefore, recycling pizza boxes is essential.</p>



<p>Unfortunately, the contaminants make pizza boxes a <a href="https://www.earth.com/news/global-recycling-day-creating-a-healthier-planet-for-all/" target="_blank" rel="noreferrer noopener">recycling</a> nightmare. Delicious, cheesy slices leave a greasy residue that renders the pizza boxes unsuitable for traditional recycling processes.</p>



<p>Compounds like peanut butter and pizza box grease are also incredibly difficult to clean off, essentially relegating many of these boxes to landfills.</p>



<h2 class="wp-block-heading" id="h-recycling-pizza-boxes">Recycling pizza boxes</h2>



<p>Researchers at Idaho National Laboratory (<a href="https://inl.gov/" target="_blank" rel="noreferrer noopener">INL</a>) have embarked on a mission to change this. Consequently, they've developed a new method to decontaminate cardboard, which could revolutionize recycling practices for food containers. </p>



<p>Their latest publication in the <em>Journal of Cleaner Production</em> details this breakthrough, highlighting a process that uses material separation capabilities to address the issue.</p>



<p>"To make specific separations possible, we need to first prove the overall concept of material separations, which is what this study accomplished," explained Aaron Wilson, the principal investigator for this project.</p>



<h2 class="wp-block-heading" id="h-dimethyl-ether-for-pizza-box-recycling">Dimethyl ether for pizza box recycling</h2>



<p>The heart of their experiment lies in the use of dimethyl ether (DME), a green solvent known for its use in refrigeration. The team designed a system with two vertical stainless-steel reactors to facilitate the extraction and separation of FOGs from contaminated cardboard. </p>



<p>The process begins by mixing broken-down cardboard pieces with DME, which pulls the contaminants out of the cardboard. The system then <a href="https://www.earth.com/news/people-recycle-know-new-products/" target="_blank" rel="noreferrer noopener">recycles</a> this solvent, allowing for continuous operation without creating waste.</p>



<p>"The reactor process allowed us to extract the contaminants into separate fractions," Wilson shared, noting the successful separation of oils, water, and dryer solids into distinct components.</p>



<h2 class="wp-block-heading" id="h-pizza-box-recycling-on-the-front-lines">Pizza box recycling on the front lines</h2>



<p>The implications of this research extend beyond just cleaner recycling.  Originally part of a research initiative linked to the Defense Advanced Research Project Agency (DARPA) <a href="https://www.darpa.mil/program/resource" target="_blank" rel="noreferrer noopener">ReSource Program</a>, the technology developed could significantly reduce the logistical footprint of military operations by transforming waste into useful resources. </p>



<p>This has potential benefits for operational security and efficiency, particularly in hostile environments where supply lines are vulnerable.</p>



<p>"Knowing that this works for the highly contaminated <a href="https://www.earth.com/news/creators-of-forever-chemicals-covered-up-the-toxic-dangers-for-decades/" target="_blank" rel="noreferrer noopener">pizza boxes</a> has helped validate the system for use in the battlefield," stated Jeff Lacey, another leading researcher on the project. </p>



<p>Lacey's team is now focused on refining the technology to enhance its portability and efficiency, critical factors for deployment in military contexts.</p>



<h2 class="wp-block-heading" id="h-sustainable-future">Sustainable future</h2>



<p>The successful application of this technology to pizza box waste not only promotes environmental sustainability but also opens doors to myriad other applications. From converting military waste to enabling more efficient battery recycling, the potential is vast.</p>



<p>"In essence, this research has many possible applications for national security and a net-zero future," Lacey concluded.</p>



<p>This initiative represents a significant step forward in tackling the recycling challenges posed by everyday waste and could pave the way for innovative <a href="https://www.earth.com/news/international-day-of-zero-waste-a-global-commitment-to-a-sustainable-future/" target="_blank" rel="noreferrer noopener">waste management</a> solutions across various sectors.</p>



<h2 class="wp-block-heading" id="h-benefits-of-recycling-pizza-boxes">Benefits of recycling pizza boxes</h2>



<p>Recycling pizza boxes offers substantial environmental and economic benefits that contribute to sustainability efforts. Here’s a detailed look at these advantages:</p>



<h3 class="wp-block-heading" id="h-reduces-waste-in-landfills">Reduces waste in landfills</h3>



<p>One of the immediate benefits of recycling pizza boxes is the reduction of waste sent to landfills. Pizza boxes are made from corrugated cardboard, which is biodegradable but can still take a considerable amount of time to decompose in landfill conditions. </p>



<p>Moreover, the presence of greases and residues can slow down this process and contribute to the production of methane, a potent greenhouse gas. By recycling, these materials are reused rather than occupying landfill space.</p>



<h3 class="wp-block-heading" id="h-conserves-natural-resources">Conserves natural resources</h3>



<p>Recycling cardboard, including pizza boxes, helps conserve valuable natural resources, particularly wood fibers. The fibers in cardboard can be recycled several times before they become too short for paper production. This means that fewer trees need to be cut down to produce new cardboard, helping to preserve forests and the biodiversity within them.</p>



<h3 class="wp-block-heading" id="h-saves-energy">Saves energy</h3>



<p>The process of recycling cardboard uses significantly less energy than producing new cardboard from virgin pulp. Energy savings arise from reduced demands in raw material extraction, transportation, and processing. By using less energy, recycling also lowers greenhouse gas emissions, contributing to climate change mitigation.</p>



<h3 class="wp-block-heading" id="h-prevents-pollution">Prevents pollution</h3>



<p>By recycling pizza boxes, pollution generated from the production of new cardboard is also reduced. The manufacturing of cardboard from virgin materials involves various chemical processes that can release pollutants into the air and water. Recycling helps to minimize these pollutants, leading to cleaner air and water.</p>



<h3 class="wp-block-heading" id="h-economic-benefits">Economic benefits </h3>



<p>Recycling creates more jobs than landfilling or incineration. The process of collecting, sorting, and processing recyclable materials is more labor-intensive than using these materials as a fuel source or burying them. This means more employment opportunities in the recycling and manufacturing industries.</p>



<h3 class="wp-block-heading" id="h-encourages-sustainable-practices">Encourages sustainable practices</h3>



<p>Recycling pizza boxes can foster a culture of recycling and sustainability within communities. When people engage in recycling, they become more aware of their waste habits and environmental impact. This awareness can lead to broader support for other sustainable practices, such as reducing plastic use, conserving water, and supporting renewable energy.</p>



<h3 class="wp-block-heading" id="h-improves-community-health-and-safety">Improves community health and safety</h3>



<p>By reducing the amount of waste in landfills and decreasing pollution from new production processes, recycling helps to improve overall community health. Less landfill waste reduces potential soil and water contamination, and fewer emissions mean cleaner air and fewer respiratory issues for the community.</p>

New recycling solution tackles greasy pizza boxes

Each day, roughly 43 million Americans indulge in at least...

<p>Did you know that the gender of your <a href="https://www.earth.com/news/doctors-are-stressed-at-work-and-at-home-during-pandemic/" target="_blank" rel="noreferrer noopener">doctor</a> could influence your health outcomes? That's right, a new study has uncovered some fascinating – and potentially life-altering – differences between how male and female physicians practice medicine.</p>



<p>This intriguing finding opens up a conversation about the subtle differences in how male and female doctors practice medicine and their impact on patient care</p>



<h2 class="wp-block-heading" id="h-female-doctors-and-patient-health">Female doctors and patient health</h2>



<p>Researchers at <a href="https://www.ucla.edu" target="_blank" rel="noreferrer noopener">UCLA</a> meticulously analyzed a massive collection of medical records – over 770,000 in total. This extensive dataset allowed them to spot trends and patterns that might not be visible in a smaller study. They honed in specifically on patients who had been hospitalized, as that's a critical point in the healthcare journey.</p>



<p>The study revealed that patients of both genders had slightly better survival chances within the 30-day period following their hospital stay if their attending physician was a woman. Importantly, this positive effect was even stronger when the patient was female.</p>



<p>Another key finding was that patients, regardless of gender, were less likely to need readmission to the hospital within 30 days of discharge when treated by a female physician.</p>



<h2 class="wp-block-heading" id="h-does-this-mean-female-doctors-are-better">Does this mean female doctors are better?</h2>



<p>The situation isn't as straightforward as simply saying one gender makes a better <a href="https://www.earth.com/news/doctors-are-using-emoji-to-diagnose-patients-in-clinics-and-hospitals/" target="_blank" rel="noreferrer noopener">doctor</a>. It's tempting to jump to conclusions, but this research doesn't support the idea that male doctors are inherently less skilled. </p>



<p>The research underscores a key insight: male and female physicians often differ subtly in their patient care approaches. These nuanced, perhaps subconscious, differences in doctor-patient interactions and decision-making can significantly affect a patient's health and recovery.</p>



<p>Studies suggest that biases might sometimes creep in. Male doctors, though well-intentioned, might underestimate the severity of symptoms reported by female patients. This misjudgment could lead to less aggressive or delayed treatment, impacting the patient's outcome.</p>



<p>Some experts observe that female physicians might have <a href="https://www.earth.com/news/most-people-lying-doctor/" target="_blank" rel="noreferrer noopener">communication</a> styles better suited to building trust and rapport with female patients. </p>



<p>Stronger doctor-patient communication could lead to more complete information sharing, better diagnoses, and more effective treatment plans.</p>



<p>Female patients may feel more at ease discussing sensitive or potentially embarrassing health issues with a female doctor. This increased comfort level could make them more likely to share vital details, allowing for better-informed medical decisions and positively influencing their health journey.</p>



<h2 class="wp-block-heading" id="h-critical-role-of-female-physicians">Critical role of female physicians</h2>



<p>This study opens a fascinating door, but it doesn't give us all the answers. We need to dig deeper to pinpoint the exact reasons why patients, particularly female patients, seem to have slightly better outcomes when treated by female physicians. </p>



<p>Is it communication style? Implicit bias? A mix of factors? More research is crucial to answer these questions fully.</p>



<p>Sadly, even with their proven skills and contributions, female <a href="https://www.earth.com/news/future-doctors-and-nurses-need-more-training-in-disaster-medicine/" target="_blank" rel="noreferrer noopener">doctors</a> often earn less than their male counterparts for the same work. This study is yet another reminder of the incredible value they bring to the healthcare system. </p>



<p>Closing the pay gap isn't just about fairness; it's about recognizing the critical role female physicians play in improving health outcomes for everyone.</p>



<h2 class="wp-block-heading" id="h-study-significance">Study significance</h2>



<p>The deeper we understand the factors behind these findings, the better we can design training and systems to improve patient care across the board. This benefits everyone, regardless of the gender of their <a href="https://www.earth.com/news/doctors-work-cut-fake-news-online-misinformation/" target="_blank" rel="noreferrer noopener">doctor</a>.</p>



<p>When everyone is compensated fairly, it attracts the best and brightest to the medical field. Ensuring pay equity could mean an even stronger healthcare system for everyone.</p>



<p>“What our findings indicate is that female and male physicians practice medicine differently, and these differences have a meaningful impact on patients' health outcomes,” said Dr. Yusuke Tsugawa. He is the associate professor-in-residence of medicine in the division of general internal medicine and health services research at the David Geffen School of Medicine at UCLA and the study’s senior author. </p>



<p>“Further research on the underlying mechanisms linking physician gender with patient outcomes, and why the benefit of receiving the treatment from female physicians is larger for female patients, has the potential to improve patient outcomes across the board," Tsugawa concluded.</p>



<p>While your doctor's gender shouldn't be the <em>only</em> factor in your decision-making, this study reminds us that it might carry more weight than we previously thought. If you're searching for a doctor, it's definitely worth considering whether a female physician might be a better fit based on your personal needs.</p>



<p>The study is published in the peer-reviewed journal&nbsp;<em><a href="https://www.acpjournals.org/doi/10.7326/M23-3163" target="_blank" rel="noreferrer noopener">Annals of Internal Medicine</a></em>.</p>
