<p>Today's <strong>Image of the Day</strong> from <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA Earth Observatory</a> features a large sediment plume from the Yangtze River that extends hundreds of kilometers off the coast of China.</p>



<p>"Brown, sediment-laden water is visible along this shallow, turbid stretch of coast year-round, but a vast plume like the one visible here is a characteristic feature of winter. Scientists have proposed several causes of this seasonal phenomenon," said NASA.</p>



<p>"The ebb and flow of tides contain enough energy to stir up sediments from the seafloor, a 2017 study found. While there are also tides in the summer, the models used in the study showed that sediment only rises to the surface in the winter. That’s when temperatures and salinities at the sea surface and bottom are similar, allowing for vertical mixing to occur and for sediment to churn higher into the water column."</p>



<p>Additional studies have suggested that the summer monsoon’s influence on currents impedes the eastward flow of sediment out of the estuaries, noted NASA.</p>



<p>"Despite what looks like a glut of suspended sediment in the water, the overall amount of it flowing from the Yangtze River has declined steadily over the past several decades. The construction of dams, including the Three Gorges Dam, has been the primary driver of this trend."</p>



<p>It is important for scientists to track the movement of suspended sediment. This material can cause direct harm to marine life, as well as indirect harm by blocking sunlight.</p>



<p>The Yangtze River, also known as the Chang Jiang in Chinese, is the longest river in Asia and the third-longest in the world, following the Nile and the <a href="https://www.earth.com/news/amazon-river-dolphins-are-at-great-risk-of-extinction-due-to-human-activities/">Amazon</a>. It flows for over 6,300 kilometers (about 3,917 miles) from the glaciers of the Qinghai-Tibet Plateau in western China to the East China Sea at Shanghai.&nbsp;</p>



<p>The Yangtze River basin is a key region for China's agriculture, industry, and hydroelectric power production. The river's waters are used for irrigation, navigation, and as a source of freshwater. The basin is home to diverse wildlife, including the critically endangered Yangtze river dolphin or Baiji, which may now be extinct.</p>

<p>Today's <strong>Image of the Day</strong> from <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA Earth Observatory</a> features the Ruki River in the Democratic Republic of the Congo (DRC). It is a tributary of the Congo River, one of the largest <a href="https://www.earth.com/news/warmer-rivers-keep-antimicrobial-resistant-genes-at-bay/">rivers</a> in the world by discharge and depth. </p>



<p>The Ruki River, previously known as the Busira, merges with the Momboyo River near the town of Basankusu to become the Lulonga River, which eventually flows into the Congo River at the town of Lisala.</p>



<p>"If the appearance of the muddy Amazon River evokes a coffee cut with cream, the Ruki River, coursing gently through the Congo Basin, is like a dark tea," said NASA.</p>



<p>"On its slow path through mostly untouched lowland rainforest in the Democratic Republic of Congo (DRC), the water leaches organic material from vegetation, prompting some researchers to think it is one of the darkest blackwater rivers on Earth. The dissolved material in this distinctive water, scientists are finding, offers clues into the carbon cycle of tropical forests."</p>



<p>In a recent study, researchers measured the chemical composition and flow of the Ruki for the first time.&nbsp;</p>



<p>"The study reported that, as the water color suggests, the Ruki is rich in dissolved organic carbon compounds. It contains four times as much organic carbon as the Congo River and 1.5 times as much as the Rio Negro, the world’s largest blackwater river and a major tributary of the Amazon," said NASA.</p>



<p>Due to this heavy carbon load, the researchers concluded that “tropical forests like those around the Ruki might not accumulate quite as much carbon as we once thought.”</p>



<p>The region around the Ruki River is rich in biodiversity, hosting various species of flora and fauna. It is part of the Congo Basin, the second-largest tropical rainforest area in the world, which is a critical habitat for endangered species and a significant carbon sink.</p>



<p>The river is vital for the livelihoods of local communities. Fishing is a crucial activity, with many people depending on it for sustenance and income. The river also supports agriculture along its banks, where communities grow crops.</p>



<p>In many parts of the DRC, rivers like the Ruki are crucial transportation corridors due to the challenging and often nonexistent road infrastructure. The river enables the movement of people and goods, facilitating trade and access to markets, health care, and education.</p>



<p>The region faces several challenges, including deforestation, overfishing, and environmental degradation, which threaten its ecological balance and the livelihoods of people who depend on it. Efforts to manage and conserve the river's resources are vital for sustainable development.</p>



<p>Understanding and protecting the Ruki River and its surroundings are crucial for the DRC's environmental sustainability, economic development, and the well-being of its communities.</p>

The Ruki River in the Democratic Republic of the Congo

<p>Today's <strong>Image of the Day</strong> from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> features dust streaming from Lago Colhué Huapi, a shallow endorheic lake located in the Chubut Province in southern Argentina.</p>



<p>"Strong northwesterly winds often race down the eastern side of the Andes Mountains and whip across the central Patagonian Desert. In the process, they sometimes lift dust from Argentina’s drying Lago Colhué Huapi, fueling intense dust storms," said NASA.</p>



<p>"Lago Colhué Huapi is a particularly rich source of dust because the shallow lake regularly grows and shrinks with variations in the flow of the Senguer River and the pace of evaporation. When lake water levels are low, as they were when MODIS captured this image, fine-grained, lightweight particles are easily transported by the wind."</p>



<h2 class="wp-block-heading" id="h-dust-activity-from-lago-colhue-huapi">Dust activity from Lago Colhué Huapi</h2>



<p><a href="https://www.earth.com/news/dust-storms-in-the-gulf-of-alaska-help-shape-the-global-climate/">Dust storms</a> in this region are most common during the summer months from December to March. There are 15 to 30 dust storms in a typical year.&nbsp;</p>



<p>"Dust storms are frequent and persistent enough in this area that they have exposed an open-air archaeological site along the lake’s edge," said NASA.</p>



<p>"The Puesto Roberts 1 site, located in an old floodplain on the southeast side of Lago Colhué Huapi, was first identified in 2019 when archaeologists noticed that winds had exposed a five-centimeter layer of sandy loam soil littered with stone tools and the bones of a wild species of llama called guanaco."</p>



<p>"Archaeologists identified 427 artifacts at the site - including stone cutting blades, milling tools, scrapers, and egg-shaped bola stones used for hunting - spread across 15 square meters, according to a 2022 study led by Heidi Hammond, an archaeologist at the National University of the Patagonia San Juan Bosco."</p>



<h2 class="wp-block-heading" id="h-more-about-lago-colhue-huapi">More about Lago Colhué Huapi</h2>



<p>This lake is an interesting geographical feature primarily because it acts as a seasonal sink for the Senguerr River, which in turn gathers waters from various smaller streams in the region. </p>



<h3 class="wp-block-heading" id="h-size">Size</h3>



<p>Due to its shallow nature, the size of Lago Colhué Huapi can vary significantly with the seasons and the amount of water it receives from its sources. During times of drought or reduced rainfall, the <a href="https://www.earth.com/news/climate-change-is-pushing-lakes-to-their-boiling-point/">lake</a> can shrink considerably, affecting the local ecosystem and the wildlife that depends on it.</p>



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



<p>The lake's surroundings are characterized by a semi-arid climate, which influences the type of vegetation and animal life that can thrive in the area. Despite the harsh conditions, the region around Lago Colhué Huapi supports a variety of bird species, making it a site of interest for birdwatchers and naturalists.</p>



<h3 class="wp-block-heading" id="h-environmental-challenges">Environmental challenges </h3>



<p>In recent years, Lago Colhué Huapi has faced environmental challenges, including the impact of <a href="https://www.earth.com/news/alarming-study-most-of-the-worlds-largest-lakes-are-quickly-losing-water/">climate change</a>, which has led to lower water levels and increased salinity. These changes pose threats to the lake's ecological balance and the species that inhabit its waters and shores. The situation at Lago Colhué Huapi serves as a reminder of the broader environmental issues facing water bodies in arid and semi-arid regions around the world.</p>

Dust streams from Lago Colhué Huapi in Argentina 

<p>Today's <strong>Image of the Day</strong> from <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA Earth Observatory</a> features thick haze over Thailand during the fire season. The photograph was captured by the VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite on March 16, 2024.</p>



<h2 class="wp-block-heading" id="h-waves-of-smoke-and-haze">Waves of smoke and haze</h2>



<p>"Each year in January and February, satellites begin to detect waves of smoke and fire in Southeast Asia, particularly in highland forests in Cambodia, Laos, Myanmar, and Thailand. Fire activity continues to increase through March and April, reaches a peak during the height of the dry season, and then fades in May with the start of the rainy season," noted NASA.</p>



<p>"Individual fires are usually small and short-lived. But they are often so numerous that smoke, along with air pollution from rural and urban areas, mixes to produce thick layers of haze that blanket the landscape." </p>



<p>"Such hazes contain mixtures of small airborne particles called aerosols and gaseous pollutants such as nitrogen dioxide, sulfur dioxide, carbon monoxide, and ozone that degrade air quality and have harmful health effects."</p>



<h2 class="wp-block-heading" id="h-haze-in-thailand-nbsp">Haze in Thailand&nbsp;</h2>



<p>An international field campaign - the Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) - was recently launched to investigate the haze in Thailand.</p>



<p>"During the last two weeks of March 2024, NASA’s DC-8 and Gulfstream III aircraft flew several flights over Chiang Mai, Bangkok, and rural areas surrounding the cities to sample air quality with several sensors. At the same time, satellites observed the haze from above," said NASA.</p>



<p>James Crawford, ASIA-AQ’s principal investigator, said the team is collaborating closely with national and local government entities in Thailand.</p>



<p>“The goal is to take as many simultaneous measurements of pollutants as possible from the ground, air, and space,” said Crawford. The team will use the data to gain a better understanding of how the haze forms, evolves chemically over time, and moves throughout the region.</p>



<h2 class="wp-block-heading" id="h-haze-and-public-health-in-thailand">Haze and public health in Thailand </h2>



<p>According to media reports, nearly 200,000 people have been hospitalized this year due to air quality in the region, with over 1.3 million people falling ill since January.&nbsp;</p>



<h3 class="wp-block-heading" id="h-root-causes">Root causes</h3>



<p>The root causes of the haze include agricultural burning, particularly of corn fields, as part of slash-and-burn practices to prepare land for the next planting cycle. This is exacerbated by the dry season when there's little rain to wash the pollutants away. </p>



<p>The situation is worsened by industrial emissions and vehicle fumes, particularly in urban areas like Bangkok​.</p>



<h3 class="wp-block-heading" id="h-sustainable-solutions-are-needed">Sustainable solutions are needed</h3>



<p>Efforts to address the crisis have been complex, involving local and transboundary issues. Much of the agricultural burning occurs not only within Thailand but also in neighboring countries like Myanmar and Laos, contributing to the transboundary nature of the haze. </p>



<p>Activists and local communities have called for sustainable solutions that do not exacerbate the poverty of smallholder farmers, emphasizing the need for affordable and realistic alternatives to burning​.</p>



<h3 class="wp-block-heading" id="h-mitigation-measures-nbsp">Mitigation measures&nbsp;</h3>



<p>The Thai government has implemented a no-burning rule until the end of April to combat wildfires and haze, but enforcement and effectiveness remain challenges​​. </p>



<p>Some measures taken to mitigate the immediate effects of pollution in urban areas include spraying water and seeding clouds to encourage rain, although these have had limited success​​.</p>



<p>This ongoing environmental crisis has sparked widespread concern among citizens, who are increasingly using public interest litigation to hold companies and the government accountable for environmental commitments. </p>



<p>With recent political changes, there is hope that the new administration will take more decisive action against the haze, possibly through more stringent regulations and international cooperation​​.</p>



<h2 class="wp-block-heading" id="h-health-impacts-of-haze">Health impacts of haze</h2>



<p>Haze poses several health hazards for those exposed to it, particularly when it contains fine particulate matter (PM2.5). Here are some of the main health risks associated with exposure to haze:</p>



<h3 class="wp-block-heading" id="h-respiratory-problems">Respiratory problems</h3>



<p>Haze can aggravate conditions such as asthma, bronchitis, and other chronic obstructive pulmonary diseases (COPD). The fine <a href="https://www.earth.com/news/heatwaves-and-air-pollution-may-double-fatal-heart-attack-risk/">particles</a> can penetrate deep into the lungs, causing inflammation and reducing lung function.</p>



<h3 class="wp-block-heading" id="h-cardiovascular-issues-and-haze">Cardiovascular issues and haze</h3>



<p>Exposure to fine particulate matter can also affect the cardiovascular system, leading to increased risk of heart attacks, strokes, and high blood pressure. Particles can affect blood vessel function and promote the formation of blood clots.</p>



<h3 class="wp-block-heading" id="h-eye-irritation">Eye irritation</h3>



<p>Haze can cause eye irritation, leading to conditions such as conjunctivitis (pink eye) or exacerbated symptoms in people with existing eye conditions.</p>



<h3 class="wp-block-heading" id="h-skin-problems">Skin problems</h3>



<p>For some people, exposure to <a href="https://www.earth.com/news/air-pollution-will-increase-dramatically-in-a-hotter-climate/">polluted air</a> can cause skin irritation or exacerbate skin conditions like eczema or psoriasis.</p>



<h3 class="wp-block-heading" id="h-reduced-immune-function">Reduced immune function</h3>



<p>There is evidence to suggest that prolonged exposure to polluted air can weaken the immune system, making individuals more susceptible to infections.</p>



<h3 class="wp-block-heading" id="h-impact-on-mental-health">Impact on mental health</h3>



<p>There are growing concerns about the impact of air pollution on <a href="https://www.earth.com/news/air-pollution-linked-to-multiple-chronic-health-conditions/">mental health</a>, with studies suggesting a link between exposure to polluted air and an increased risk of depression and anxiety.</p>



<h3 class="wp-block-heading" id="h-pregnant-women-and-children">Pregnant women and children</h3>



<p>Pregnant women, children, and the elderly are particularly vulnerable to the effects of haze. There may be increased risks of preterm birth and low birth weight in babies, and children may experience delayed development and reduced lung function.</p>



<p>The health impacts of haze can be mitigated by staying indoors on days when air quality is particularly poor, using air purifiers, wearing masks designed to filter out fine particles, and following local health advisories.</p>

The Ebro River on the northeast coast of Spain

<p>We all know that a mom's health and nutrition matter before and during pregnancy. But what about <a href="https://www.earth.com/news/dads-metabolic-health-advantages-kids/" target="_blank" rel="noreferrer noopener">dads</a>? A new study suggests that a father's diet plays a surprisingly big role in the health of his future children. </p>



<p>Scientists are discovering that a father's diet can change his offspring's metabolism, health risks, and even emotional well-being.</p>



<h2 class="wp-block-heading" id="h-father-s-diet">Father's diet</h2>



<p>The researchers used a mouse model to explore how a <a href="https://www.earth.com/news/fathers-life-experiences-offspring/" target="_blank" rel="noreferrer noopener">father</a>'s diet may affect his future offspring. Here's what they discovered:</p>



<h3 class="wp-block-heading" id="h-anxious-sons">Anxious sons</h3>



<p>Fathers who consumed a diet with less protein and more carbohydrates were more likely to have male offspring exhibiting increased signs of anxiety.</p>



<p>This anxiety was measured by researchers observing how much time these mice preferred to spend in the perceived "safer" areas of a maze.</p>



<h3 class="wp-block-heading" id="h-at-risk-daughters">At-risk daughters</h3>



<p><a href="https://www.earth.com/news/older-dad-health-risks/" target="_blank" rel="noreferrer noopener">Fathers</a> whose diets were primarily composed of high amounts of fat were more likely to produce female offspring with a greater degree of body fat. Furthermore, these daughters displayed early indicators of metabolic disease, including conditions like diabetes.</p>



<p>The study confirms that a father's diet matters before a baby is even conceived. It's not just about the calories - but also where those calories come from. </p>



<p>"By [changing] mixtures of protein, fat, and carbs in the father's diet we could influence specific features of his sons and daughters health and behavior," said Professor Stephen Simpson, co-senior author and academic director of the Charles Perkins Centre at the <a href="https://www.sydney.edu.au" target="_blank" rel="noreferrer noopener">University of Sydney</a>.</p>



<h2 class="wp-block-heading" id="h-impact-of-father-s-diet-at-molecular-level">Impact of father's diet at molecular level</h2>



<p>A father's diet can influence the development of sperm cells. Tiny molecules attached to the <a href="https://www.earth.com/news/exposure-to-ddt-alters-sperm-putting-children-at-risk/" target="_blank" rel="noreferrer noopener">sperm</a>, influenced by the nutrients he consumes, may act like tiny flags. These flags can potentially alter how a child's genes are expressed, even though the DNA itself remains unchanged.</p>



<p>This means a father's dietary choices can influence how certain genes are "turned on" or "turned off" in his offspring, potentially impacting their health and development.</p>



<p>It's not simply about how much a father eats, but what he eats. The specific balance of macronutrients – protein, fat, and carbohydrates – appears to have a significant impact. </p>



<p>For example, the study suggests that low-protein, high-carb diets in fathers may be linked to increased anxiety in sons, while high-fat diets may be associated with increased body fat and metabolic disease risk in daughters.</p>



<p>Overall, this research highlights the importance of a comprehensive approach to family planning that considers the health of both the mother and the father. By focusing on a balanced diet rich in essential nutrients before conception, parents may be laying the groundwork for a healthier future generation.</p>



<h2 class="wp-block-heading" id="h-dads-to-be-take-note">Dads-to-be, take note</h2>



<p>While we can't directly apply mice studies to humans, these findings are huge. They imply that we need to take a closer look at the diet of both parents when thinking about family planning and the long-term health of <a href="https://www.earth.com/news/happy-childhood-health-adulthood/" target="_blank" rel="noreferrer noopener">children</a>. </p>



<p>"Our study is a step towards establishing dietary guidelines for fathers-to-be, with the ultimate goal of lowering the risk of metabolic disease and mood disorders in the next generation," said co-author Professor Romain Barrès.</p>



<p>It might be time to pay extra attention to nutrition alongside your partner. A balanced diet rich in a variety of nutrients seems like the way to go. Ditching the junk food in favor of some home-cooked meals might benefit your own health as well as that of your future children.</p>



<h2 class="wp-block-heading" id="h-ideal-father-s-diet">Ideal father's diet</h2>



<p>An ideal father's diet is crucial not just for his own health but also for potentially influencing the health of his future children. The diet should be comprehensive, incorporating a variety of nutrients that contribute to good health and fertility. Here’s a detailed guide on what an ideal diet for a prospective father might include:</p>

<p>Get ready to witness an incredibly rare and spectacular sight. A plant so extraordinary it's been nicknamed the Sapphire Tower is blooming for the first time in a decade at the <a href="https://bbgardens.org" target="_blank" rel="noreferrer noopener">Birmingham Botanical Gardens</a>. </p>



<p>This "otherworldly" beauty from the Chilean Andes is a must-see, but you'll have to hurry – these <a href="https://www.earth.com/wp-content/uploads/2024/04/sapphire-tower-plant-blooms_puya-alpestris_1m.jpg" target="_blank" rel="noreferrer noopener">breathtaking blooms</a> won't last long.</p>



<h2 class="wp-block-heading" id="h-what-is-the-sapphire-tower">What is the Sapphire Tower?</h2>



<p>The Sapphire Tower, or <a href="https://earthpedia.earth.com/plant-encyclopedia/angiosperms/bromeliaceae/puya-alpestris/" target="_blank" rel="noreferrer noopener"><em>Puya alpestris</em></a>, is a fascinating and visually striking plant native to the Andean regions of Chile. </p>



<p>Part of the bromeliad family, which includes more familiar plants like pineapples and Spanish moss, <em>Puya alpestris</em> is particularly notable for its unique and vibrant characteristics.</p>



<h3 class="wp-block-heading">Appearance and growth</h3>



<p>The Sapphire Tower is characterized by its rosettes of silver-green leaves that are long, narrow, and edged with sharp spines. </p>



<p>The plant can grow quite large, typically reaching heights of up to a meter or more. It's known for its dramatic <a href="https://www.earth.com/earthpedia-articles/7-beautiful-flowering-trees-and-how-to-identify-them/" target="_blank" rel="noreferrer noopener">flowering</a> stalks, which can extend several meters high, far above the foliage.</p>



<p>The flowers themselves are what give the Sapphire Tower its name. They bloom in a striking metallic blue to turquoise color, and they are densely packed on the towering spikes. </p>



<p>These blooms are not only rare but also ephemeral, typically appearing only after many years of growth. The plant’s blooming cycle is particularly slow, often taking up to a decade to produce flowers.</p>



<h3 class="wp-block-heading">Pollination and ecological role</h3>



<p>In its native habitat in Chile, the <em><a href="https://www.earth.com/wp-content/uploads/2024/04/sapphire-tower-plant_puya-alpestris_1.jpg" target="_blank" rel="noreferrer noopener">Puya alpestris</a></em> is adapted to being pollinated by birds, particularly hummingbirds. </p>



<p>The shape of the flowers and their arrangement on the tall spike are perfectly suited to facilitate bird pollination. </p>



<p>The coloration of the flowers is also believed to be an adaptation to attract these specific pollinators.</p>



<h3 class="wp-block-heading">Sapphire Tower cultivation and care</h3>



<p>Outside of its native range, cultivating <em>Puya alpestris</em> can be challenging. It requires well-draining soil, as it is adapted to the rocky soils of mountainous regions. </p>



<p>The plant prefers full sun and tolerates drought well. This is due to its ability to store water in its thick leaves, similar to other bromeliads. </p>



<p>In regions outside of Chile, the <em>Puya alpestris</em> is often grown in botanical gardens. It is also grown as an ornamental plant by enthusiasts who appreciate its dramatic appearance and rare blooming.</p>



<h2 class="wp-block-heading" id="h-pollinating-the-sapphire-tower">Pollinating the Sapphire Tower</h2>



<p>In their natural habitat, Sapphire Towers rely on hummingbirds for pollination. But in a botanical garden, dedicated horticulturists like Alberto Trinco step in to give nature a helping hand.</p>



<p>"Each flower only lasts a few days, giving us a limited window of time to give nature a helping hand," explains Trinco. "It is very slow-growing, so to witness its spectacular blooms is both exciting and rare."</p>



<p>Their job is to carefully transfer pollen from one <a href="https://www.earth.com/earthpedia-articles/5-easiest-perennial-flowers-to-grow-in-your-garden/" target="_blank" rel="noreferrer noopener">flower</a> to another – a delicate process with a brief window for success.</p>



<h2 class="wp-block-heading" id="h-why-pollination-is-important-to-sapphire-tower-plants">Why pollination is important to Sapphire Tower plants</h2>



<p>Pollination plays a vital role in the life cycle of plants such as the Sapphire Tower. This process is essential because it leads to the production of seeds, which are crucial for the propagation and survival of the species. </p>



<p>By transferring pollen from the male structures of one <a href="https://www.earth.com/plant-encyclopedia/angiosperms/" target="_blank" rel="noreferrer noopener">flower</a> to the female structures of another, pollination initiates the development of seeds that will eventually grow into new plants.</p>



<p>For the Sapphire Tower, which blooms infrequently and only under specific conditions, successful pollination is particularly significant. </p>



<p>The seeds produced through this process ensure the continuation of the species, allowing it to thrive in its natural habitats. </p>



<p>These seeds carry the genetic blueprint of the plants, enhancing genetic diversity. This diversity is crucial for adapting to changing environmental conditions and resisting diseases and pests.</p>



<p>By preserving the species through natural reproductive processes like pollination, we ensure its survival. This allows future generations to enjoy and appreciate the extraordinary beauty of the Sapphire Tower.</p>



<p>The plant’s unique characteristics and striking appearance make it a valuable specimen for botanical gardens and plant enthusiasts. </p>



<p>Thus, effective pollination not only supports the ecological balance in the plant's native environment but also enhances human appreciation and understanding of biodiversity.</p>

Rare 'Sapphire Tower' plant blooms for the first time in a decade

Get ready to witness an incredibly rare and spectacular sight....

<p>Psilocybin, the primary psychoactive component in “magic mushrooms” of the genus <em>Psilocybe</em>, has recently gained attention not only as a popular recreational drug but also in the realm of medicine for its potential therapeutic benefits.&nbsp;</p>



<h2 class="wp-block-heading" id="h-how-is-psilocybin-produced-by-magic-mushrooms">How is psilocybin produced by magic mushrooms?</h2>



<p>Notably, the psilocybin found in magic mushrooms has shown promise in treating <a href="https://www.earth.com/news/magic-mushrooms-depression-brain/">depression</a>, addiction, and anxiety, reaching advanced stages of clinical trials as a potential pharmaceutical treatment. Now, a study led by the <a href="https://www.i-med.ac.at/universitaet/index.html.en" target="_blank" rel="noreferrer noopener">Medical University of Innsbruck</a> has comprehensively examined how psilocybin is produced by magic <a href="https://www.earth.com/news/scientists-learn-why-psilocybin-mushrooms-make-you-hallucinate/">mushrooms</a>.</p>



<p>Produced by a complex biochemical process from the amino acid L-tryptophan, psilocybin's synthesis involves critical enzymes, including PsiM, a methyltransferase.&nbsp;</p>



<p>“There are many methyl transfer reactions in nature,” said co-author Dirk Hoffmeister, a professor of pharmaceutical microbiology at <a href="https://www.uni-jena.de/en">Friedrich Schiller University Jena</a> and leader of a research group at the <a href="https://www.leibniz-hki.de/en/">Leibniz Institute for Natural Product Research and Infection Biology - Hans Knöll Institute</a> (Leibniz-HKI). “Here, we asked ourselves how exactly psilocybin production is accomplished.”</p>



<h2 class="wp-block-heading" id="h-psim-enzyme-s-role-in-psilocybin-production">PsiM enzyme's role in psilocybin production</h2>



<p>In&nbsp; a collaborative effort, experts from the Medical University of Innsbruck, led by crystallographer Bernhard Rupp, and Hoffmeister's team at Jena delved into the PsiM enzyme's role in psilocybin production using biochemical analysis and X-ray crystal structure analysis, which visualizes proteins at the atomic level.&nbsp;</p>



<p>Their findings revealed that PsiM, crucial for the last two steps of psilocybin synthesis, bears significant structural similarities to enzymes typically involved in RNA modification. Despite some differences, these similarities suggest that PsiM evolved from an RNA methyltransferase, which originally could attach only one methyl group to its target.</p>



<p>The experts also found that a single amino acid change in PsiM enabled it to carry out two consecutive methylation reactions, crucial for converting the psilocybin precursor norbaeocystin into psilocybin. This precursor structurally mimics part of RNA but undergoes double methylation, a key step in psilocybin production.</p>



<h2 class="wp-block-heading" id="h-future-biotechnological-applications-in-creating-psilocybin">Future biotechnological applications in creating psilocybin</h2>



<p>Moreover, the researchers explored whether PsiM could add a third methyl group to convert psilocybin into aeruginascin, a naturally occurring psilocybin analog. The scientific community has long debated whether aeruginascin is a byproduct of psilocybin biosynthesis.&nbsp;</p>



<p>“This is clearly not the case. PsiM is not able to convert psilocybin to aeruginascin,” Hoffmeister said. While definitively ruling out PsiM's involvement in aeruginascin production, this finding highlights its potential for future biotechnological applications in creating psilocybin.</p>



<p>“Overall, our results can help to develop new variants of psilocybin with improved therapeutic properties and to produce them biotechnologically,” Hoffmeister concluded.</p>



<h2 class="wp-block-heading" id="h-more-about-magic-mushrooms">More about magic mushrooms</h2>



<p>Magic mushrooms have been used for thousands of years in various cultural and religious rituals, primarily for their ability to induce profound changes in perception, mood, and thought. Upon ingestion, psilocybin is converted in the body to psilocin, which is responsible for the <a href="https://www.earth.com/news/study-offers-new-explanation-for-how-psychedelic-drugs-work/">psychedelic effects</a>.</p>



<h3 class="wp-block-heading" id="h-experience-of-magic-mushrooms-nbsp">Experience of magic mushrooms&nbsp;</h3>



<p>The experience of taking magic mushrooms can vary greatly depending on the dose, individual psychology, and environmental setting. </p>



<p>Common effects include visual and auditory <a href="https://www.earth.com/news/scientists-learn-why-psilocybin-mushrooms-make-you-hallucinate/">hallucinations</a>, an altered sense of time, euphoria, and a feeling of deep connection to others and the natural world. However, users can also experience negative effects such as anxiety, paranoia, and nausea.</p>



<h3 class="wp-block-heading" id="h-scientific-interest-nbsp">Scientific interest&nbsp;</h3>



<p>Scientific interest in psilocybin has grown in recent years, especially for its potential therapeutic benefits. Research suggests that psilocybin may help treat depression, anxiety, PTSD, and addiction.&nbsp;</p>



<p>These studies have shown that psilocybin can create lasting changes in personality and attitude towards life, often characterized by increased openness and a greater sense of peace.</p>



<h3 class="wp-block-heading" id="h-legal-landscape-nbsp">Legal landscape&nbsp;</h3>



<p>Despite their potential benefits, <a href="https://www.earth.com/news/how-psilocybin-mushrooms-got-their-magic/">magic</a> mushrooms are classified as Schedule I substances in the United States and are illegal in many other countries. This classification is due to their high potential for abuse and lack of recognized medical value under current laws.&nbsp;</p>



<p>However, the legal landscape is slowly changing as more research highlights the therapeutic potential of psilocybin, leading some regions to reconsider their stance on these substances.</p>



<p>The study is published in the journal <a href="http://dx.doi.org/10.1038/s41467-024-46997-z" target="_blank" rel="noreferrer noopener"><em>Nature Communications</em></a><em>.</em></p>
