As the sky darkens tonight, the Flower Moon will rise, casting its luminous glow across the world. Despite being a micromoon, it will still command attention.



The Flower Moon is named for the abundance of blooming flowers that typically appear&nbsp;this month. It reminds us to pause and reflect as the <a href="https://www.earth.com/news/how-the-sun-might-be-making-water-on-the-moon/" target="_blank" rel="noreferrer noopener">night</a> sky takes on a calm, serene appearance.



<h2 class="wp-block-heading" id="h-meaning-of-the-flower-moon">Meaning of the Flower Moon</h2>



Long ago, Native American tribes named May’s full moon the Flower Moon as a tribute to nature’s seasonal spectacle.



Spring awakens, flowers bloom, and the moon - like a silver lantern - watches over the Earth. The Comanche tribe saw the blooming fields and named it the Flower Moon, a time of growth and renewal.



The Creek and Choctaw people, however, called it the Mulberry Moon. Mulberries ripened, offering food and dye, and the moon marked the season of abundance. 



The Cree tribe, listening to the chorus of frogs, named it the Frog Moon. Spring returned, and with it, the croaking songs echoed through the <a href="https://www.earth.com/news/total-lunar-eclipse-will-paint-the-moon-blood-red-tomorrow/" target="_blank" rel="noreferrer noopener">night</a>.



For the Anishnaabe tribe, the Blossom Moon symbolized nature’s floral display. Meanwhile, the Apache noticed the trees coming alive with green leaves. They called this moon the “season when the leaves are green,” a simple yet vivid reminder of nature’s cycle.



<h2 class="wp-block-heading" id="h-micromoon-with-a-big-presence">Micromoon with a big presence</h2>



Tonight's Flower Moon is known as a micromoon. Its orbit pulls it farther from Earth, stretching to a distance of 251,939 miles. 



<a href="https://spaceplace.nasa.gov/moon-distance/en/" target="_blank" rel="noreferrer noopener">NASA confirms</a> that this extra distance causes the <a href="https://www.earth.com/news/dry-side-of-the-moon-reveals-new-details-about-its-evolution/" target="_blank" rel="noreferrer noopener">moon</a> to appear smaller than usual. Its average distance sits at 238,855 miles, making the Flower Moon a subtle presence in the sky.



Still, the moonlight gently washes over the night, casting a soft, silvery glow that gives the landscape a dreamlike quality.



As the sun dips below the horizon, the moon will climb slowly in the southeastern sky. By midnight, it will hang high above. For the best view, find a dark, open space away from city lights. 



<h2 class="wp-block-heading" id="h-flower-moon-connects-us-to-nature">Flower Moon connects us to nature</h2>



Throughout history, people have looked to the moon as a guide for planting, harvesting, and marking time. Farmers once relied on the full moon’s light to work late into the night. 



The Flower Moon, with its connection to the season’s peak bloom, became a symbol of abundance and renewal.



Today, the Flower Moon is still a beautiful sight to behold, but it's no longer tied to specific cultural events.



<h2 class="wp-block-heading" id="h-full-moons-in-2025">Full Moons in 2025</h2>



May’s Flower Moon closes the chapter on a series of micromoons in 2025. The first two appeared in January and February - each one pulling away from Earth, and each one smaller than the last. The Flower Moon, the final act, drifts farther than ever.



The Flower Moon may mark the end of the micromoons, but the lunar calendar is far from over. June will bring the Strawberry Moon, named for the ripening berries that herald summer’s arrival. 



July’s Buck Moon will signal the growth of antlers on young deer, a symbol of nature’s <a href="https://www.earth.com/news/saturns-rings-beautiful-iconic-will-disappear-this-weekend-ring-plane-crossing/" target="_blank" rel="noreferrer noopener">cycle</a> of renewal.



August will usher in the Sturgeon Moon - a nod to the fish that once filled North American rivers. September’s Corn Moon will shine as the cornfields sway in the wind. 



October will bring the first of three supermoons, the Harvest Moon, its light brighter and larger than usual. November’s Beaver Moon and December’s Cold Moon will complete the cycle.



<h2 class="wp-block-heading" id="h-eclipses-and-celestial-drama-in-2025">Eclipses and celestial drama in 2025</h2>



This year, the night sky holds more than full moons. September will bring two dramatic eclipses, each one a spectacle in its own right.



On September 7 and 8, a total lunar eclipse will turn the moon a haunting shade of red. A blood moon, some call it. The eclipse will be visible across Europe, Africa, Asia, Australia, and parts of South America.



Later, on September 21, the moon will slide between the sun and Earth, creating a partial solar eclipse. 



Those in Australia, Antarctica, and the Pacific Ocean will witness the sun’s light dim as the moon casts its shadow.

Waste water in the world. Grass die and all life on the Earth.

Officials: California Is Meeting Water Conservation Targets. A state water official said Californians have met a water conservation target for a third consecutive month during the grinding drought.
The State Water Resources Control Board on Thursday will release statewide conservation figures for August.
Max Gomberg, a senior climate scientist for the board, declined to provide specific figures ahead of the announcement but said he expects the results to meet the 25 percent savings goal set by Gov. Jerry Brown. Officials: California Is Meeting Water Conservation Targets
However, Gomberg warned that Californians can't allow themselves to be distracted by the hype of a coming El Nino weather pattern that has raised hopes that it will break California's four-year drought.
He said an El Nino doesn't guarantee a wet winter for<a href="https://www.bing.com/search?q=california&amp;cvid=6eed2d58f00e47cda9420ca2a2028cde&amp;FORM=ANAB01&amp;PC=HCTS"> California</a> and urged people to keep saving water.
"We need to continue the conservation efforts," he said. "People need to keep on doing what they've been doing."
The state reported savings of 27 percent in June and 31 percent in July.
The board also is expected to release figures for August showing how each community is performing. The mandate by Brown gave each city an individual conservation target based on water use in the same month of 2013, the year before Brown declared a drought emergency.
Some of the state's largest cities contacted independently reported meeting their mandates.
Officials in Los Angeles said the city saw savings of 17 percent in August, beating its target of 16 percent. Fresno reported a 28 percent drop, hitting its requirement. Water use in San Diego was 21 percent lower, exceeding its mandated cutback of 16 percent.
State officials said they are working with cities and water districts that have failed to meet targeted cuts.
Gomberg said climate change - signaled by warmer temperatures, a low snowpack and intense wildfires - has made water conservation an ongoing effort.
"Climate change is not something that's happening in the future," Gomberg said. "California is already dealing with the impacts."

Food Industry CEOs Call For Climate Change Deal. The CEOs of several major food and beverage companies are calling on world leaders to push for a meaningful agreement at the <a href="https://www.earth.com/news/united-nations-bans-trade-of-african-grey-parrots/">United Nation's</a> conference on climate change later this year in Paris.
The 10 companies, including cereal maker General Mills and candy maker Mars Inc., will run an open letter as a full-page ad in the Financial Times and <a href="https://www.bing.com/search?q=wasgington+post&amp;cvid=42693e6e1cf040309249b3f476fa3e61&amp;FORM=ANAB01&amp;PC=HCTS">Washington Post</a> on Thursday. They say they will "re-energize" their own efforts to make their supply chains more sustainable as well.
"We are asking you to embrace the opportunity presented to you in Paris, and to come back with a sound agreement, properly financed, that can affect real change," the open letter reads.
The effort was organized by the environmental nonprofit Ceres, which is inviting other food and beverage companies to join in the commitment. Food Industry CEOs Call For Climate Change Deal
None of the companies involved would say their own practices are perfect, according to Anne Kelly, who directs Ceres' climate policy program, but they've demonstrated a commitment to changing.
Others signing the letter are the CEOs of Unilever, Dannon, Ben &amp; Jerry's, Kellogg, Nestle USA, New Belgium Brewing, Stonyfield Farms and Clif Bar. Representatives of some of the companies also will take part in a bipartisan congressional roundtable briefing Thursday in Washington, D.C.

India Pledges To Slash Carbon Emissions By 35 Percent. As the last major economy to submit a target for a global climate pact, India is pledging to reduce the intensity of its carbon emissions and boost the share of electricity produced from sources other than fossil fuels to 40 percent by 2030.
The world's third-largest carbon polluter filed its climate action plan to the <a href="https://www.bing.com/search?q=germany&amp;cvid=16f93c49322b4d40b31515606b375c86&amp;FORM=ANAB01&amp;PC=HCTS">Germany</a>-based U.N. climate secretariat late Thursday, the deadline for pledges before a December conference in Paris, where governments are supposed to adopt a landmark deal to fight climate change.
In a 38-page submission citing Mahatma Gandhi, the Indian government said it would slash the rate of emissions relative to gross domestic product by 33-35 percent by 2030 from 2005 levels.
It said India has already reduced its carbon intensity by 12 percent since 2005.
The carbon intensity goal will allow India's emissions to grow as its economy expands, but at a lower rate than now.
"It is estimated that more than half of India of 2030 is yet to be built," the government said.
Environmental groups following the U.N. climate talks welcomed India's pledge.
"India now has positioned itself as a global leader in clean energy, and is poised to play an active and influential role in the international climate negotiations this December," said Rhea Suh, president of the Natural Resources Defense Council, an environmental think tank based in New York.
India plans a fivefold boost in renewable energy capacity in the next five years to 175 gigawatts, including solar power, wind, biomass and small hydropower dams.
Even with a major boost of renewable energy, India is also planning to expand coal power - the biggest source of emissions - to satisfy its energy needs. Coal-fired power plants account for about 60 percent of India's installed power capacity.
By 2030, the government said its installed capacity from "non-fossil fuel based energy resources" would grow to 40 percent. It wasn't immediately clear whether that would also include nuclear power.
India said boosting its renewables to that level would require help with transfer of clean technology and financing - two of the crunch issues before the Paris deal, which is supposed to apply to all countries but also include provisions for rich countries to help poor countries fight climate change and adapt to its consequences.
Scientists say the heat-trapping carbon emissions released by the burning of fossil fuels - coal, oil and gas - are a key driver of rising temperatures that could lead to potentially catastrophic impacts, including flooding of island nations and intensifying droughts.
China and the U.S. are the only countries with higher emissions than India. As a bloc, the 28-nation European Union's emissions are also higher.
Like other developed countries, the U.S. and the EU committed to absolute reduction targets, while China pledged that its emissions would stop growing by 2030. India, with more than 300 million people living in poverty, wasn't expected to offer a peak year because its emissions are projected to increase for decades as energy demand rises along with economic growth.
Indian Environment Minister Prakash Javadekar last week told The Associated Press that developed countries should "vacate the carbon space" to allow India's emissions to increase. "That <a href="http://www.earth.com/news/study-reveals-carbon-cycle-trends-of-the-past-50-million-years/">carbon</a> space demand is climate justice," he said.
Two climate research groups this week said that the pledges put forth before the Paris conference would slow down global warming but projected that temperatures would still rise by 2.7 and 3.5 degrees C (4.9 and 6.3 degrees F), respectively. India Pledges To Slash Carbon Emissions By 35 Percent

Without those cuts, the group calculated that there would be an additional 0.5-1.1 C (0.9-2.0 F) of warming. A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O₃). Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F). The atmospheres of Venus, Mars and Titan also contain greenhouse gases.
Currently, temperatures are about 1.8 C (3.2 F) warmer than in pre-industrial times.

Currently, temperatures are about 1.8 C (3.2 F) warmer than in pre-industrial times. Carbon is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust. Three isotopes occur naturally, ¹²C and ¹³C being stable, while ¹⁴C is a radionuclide, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity.

EPA Sets New Ozone Pollution Standard. The Obama administration on Thursday established stricter limits on the smog-causing pollution linked to asthma and respiratory illness, drawing swift condemnation from business leaders and Republicans who warned of damage to the economy.
The Environmental Protection Agency said the new standard of 70 parts per billion will reduce exposure to dangerous ozone pollution and prevent thousands of <a href="http://www.earth.com/news/fine-particle-pollution-may-cause-children-to-develop-asthma/">asthma</a> attacks and emergency room visits and hundreds of premature deaths each year.
Environmental and health groups argued that the rules fall short. The new standard is below the current standard of 75 parts per billion but at the high end of a range announced by the EPA last fall.
The move fulfills a long-delayed campaign promise by President Barack Obama as he works to cement a legacy on climate change and other environmental policies before leaving office in January 2017. After pledging during his first presidential campaign to tighten ozone limits, Obama backtracked in 2011 by yanking the EPA's proposed ozone limits amid intense pressure from industry and the GOP.
White House spokesman Josh Earnest said Thursday the new ozone rule fits into Obama's strategy to cut pollution while promoting economic growth.
Still, the EPA's long-awaited action set up a fresh confrontation with Republicans already angry about the administration's plans to curb carbon pollution from coal-fired power plants and regulate small streams and wetlands.
Business groups said a new ozone standard is unnecessary and could jeopardize jobs. Environmental and public health groups said the new standard was a step in the right direction but did not go far enough.
EPA Administrator Gina McCarthy acknowledged the intense criticism from all sides, but said her job was to set science-backed standards that protect the health of the American people, not take actions "based on popularity."
In a lengthy statement to reporters, McCarthy said the best available clinical data show that 72 parts per billion "is the lowest ozone exposure that causes adverse health effects in healthy, exercising adults."
From there, she decided to add in a "margin of safety" to protect vulnerable populations, including children, the elderly and those suffering from heart and lung ailments. Setting the level at 70 parts per billion "will essentially eliminate exposures to the levels that clinical studies clearly show are harmful," McCarthy said.
McCarthy said the final judgment was hers, and she aimed to set a standard that was "not too high and not too low. It's very challenging. There's no bright line."
Harold Wimmer, president and CEO of the American Lung Association, said the new standard "simply does not reflect what the science shows is necessary to truly protect public health."
The lung association and other groups have pushed for an ozone limit of 60 parts per billion, saying it would have given Americans much greater health protections. The stricter standard would prevent thousands of premature deaths and nearly 2 million asthma attacks per year, the lung association said.
Business groups also reacted harshly. The National Association of Manufacturers and other groups had lobbied the White House in recent months and spent millions on a TV ad campaign decrying the pending ozone rule as an overreach and a job killer.
"We know that this regulation could have been worse, but it still feels like a punch in the gut," said Tom Riordan, president and CEO of the Wisconsin-based Neenah Enterprises Inc. and task force leader for the manufacturers group.
Riordan said the EPA rule put "politics above job creation" and said manufacturers across the country, especially smaller ones, "will be forced to choose between navigating this rule and hiring new workers, between complying with Washington's mandates and giving raises to their employees."
The rule issued Thursday meets a court-ordered deadline set after public health groups sued in the wake of the administration's 2011 withdrawal of ozone rules.
At least one environmental group vowed to challenge the new standard in court, and business groups said they also were considering a legal challenge.
Cutting ozone emissions to 70 parts per billion would cost industry about $1.4 billion in 2025, the EPA said, far below benefits estimated at $2.9 billion to $5.9 billion annually.
Aiming to smooth the transition, the EPA plans to give states that have the most ozone up to 2037 to come into compliance. But McCarthy said most of the U.S. won't have to take any action, thanks to existing pollution programs and previous EPA limits on pollutants such as mercury and carbon dioxide that have the side benefit of reducing ozone.
The EPA said only 14 U.S. counties would likely fail to meet a standard of 70 parts per billion in 2025, a figure challenged by business groups and Republicans.
The new rules could affect job growth in nearly one-third of the nation's 3,000 counties, said Jack Gerard, president of the American Petroleum Institute, the oil industry's top lobbying group. That's up from 217 counties affected at the current ozone standard, he said.

India Pledges To Slash Carbon Emissions By 35 Percent. As the last major economy to submit a target for a global climate pact, India is pledging to reduce the intensity of its carbon emissions and boost the share of electricity produced from sources other than fossil fuels to 40 percent by 2030.
The world's third-largest carbon polluter filed its climate action plan to the <a href="https://www.bing.com/search?q=germany&amp;cvid=59ffa7f4d12f4d5e852c6e0459c40a0a&amp;FORM=ANAB01&amp;PC=HCTS">Germany</a>-based U.N. climate secretariat late Thursday, the deadline for pledges before a December conference in Paris, where governments are supposed to adopt a landmark deal to fight climate change.
In a 38-page submission citing Mahatma Gandhi, the <a href="http://www.earth.com/video/indian-ocean-tsunami-reshaped-the-coast-of-sumatra/">Indian</a> government said it would slash the rate of emissions relative to gross domestic product by 33-35 percent by 2030 from 2005 levels.
It said India has already reduced its carbon intensity by 12 percent since 2005.
The carbon intensity goal will allow India's emissions to grow as its economy expands, but at a lower rate than now.
"It is estimated that more than half of India of 2030 is yet to be built," the government said.
Environmental groups following the U.N. climate talks welcomed India's pledge.
"India now has positioned itself as a global leader in clean energy, and is poised to play an active and influential role in the international climate negotiations this December," said Rhea Suh, president of the Natural Resources Defense Council, an environmental think tank based in New York.
India plans a fivefold boost in renewable energy capacity in the next five years to 175 gigawatts, including solar power, wind, biomass and small hydropower dams.
Even with a major boost of renewable energy, India is also planning to expand coal power - the biggest source of emissions - to satisfy its energy needs. Coal-fired power plants account for about 60 percent of India's installed power capacity.
By 2030, the government said its installed capacity from "non-fossil fuel based energy resources" would grow to 40 percent. It wasn't immediately clear whether that would also include nuclear power.
India said boosting its renewables to that level would require help with transfer of clean technology and financing - two of the crunch issues before the Paris deal, which is supposed to apply to all countries but also include provisions for rich countries to help poor countries fight climate change and adapt to its consequences.
Scientists say the heat-trapping carbon emissions released by the burning of fossil fuels - coal, oil and gas - are a key driver of rising temperatures that could lead to potentially catastrophic impacts, including flooding of island nations and intensifying droughts.
China and the U.S. are the only countries with higher emissions than India. As a bloc, the 28-nation European Union's emissions are also higher.
Like other developed countries, the U.S. and the EU committed to absolute reduction targets, while China pledged that its emissions would stop growing by 2030. India, with more than 300 million people living in poverty, wasn't expected to offer a peak year because its emissions are projected to increase for decades as energy demand rises along with economic growth.
Indian Environment Minister Prakash Javadekar last week told The Associated Press that developed countries should "vacate the carbon space" to allow India's emissions to increase. "That carbon space demand is climate justice," he said.
Two climate research groups this week said that the pledges put forth before the Paris conference would slow down global warming but projected that temperatures would still rise by 2.7 and 3.5 degrees C (4.9 and 6.3 degrees F), respectively.

Corals Also Need A Balanced Diet. Researchers examine nutrient enrichment and bleaching resilience in Red Sea corals

A new study found that a nutrient-rich, balanced diet is beneficial to corals during stressful thermal events. The research led by scientists at the University of <a href="https://www.bing.com/search?q=flordia&amp;cvid=d9cf3f84713b48dfa49f365baf7e6659&amp;FORM=ANAB01&amp;PC=HCTS">Miami</a> (UM) Rosenstiel School of Marine and Atmospheric Science and the Centre Scientifique de Monaco concluded that the particular nutrient balance in seawater is what matters most.Corals Also Need A Balanced Diet

To test which nutrients were more beneficial to corals during elevated temperature conditions, the scientists fed them two types - inorganic nutrients of <a href="http://www.earth.com/news/scientists-identify-molecular-link-between-nitrogen-and-plant-growth/">nitrogen</a> and phosphorus commonly found in the ocean as a result of fertilizers and sewage runoff, and organic nutrients of zooplankton, tiny animals in the ocean that coral are known to feed on.

The research team placed specimens of the yellow scroll coral, Turbinaria reniformis, collected from the Red Sea in separate seawater tanks with varying temperature and nutrients. The corals were subjected to two different inorganic nutrient enrichment scenarios - increased nitrogen only or increased nitrogen and phosphorus at varying temperatures - 25 degrees Celsius to represent normal temperature conditions and 30 degrees Celsius to represent thermal stress conditions. Some of the corals also received organic nutrient enrichment of tiny ocean animals called zooplankton during the laboratory experiment. All of the corals were then returned to normal temperature conditions to examine their recovery.

"We found that the coral's resilience to thermal stress totally depends on the kind of inorganic enrichment - if it's 'balanced' or not," said Erica Towle, an alumna of the UM Rosenstiel School.

The researchers found that excess nitrogen alone and zooplankton made high-temperature bleaching events worse. While excess nitrogen in combination with extra phosphorus and zooplankton afford the coral resilience to bleaching. This study is one of the first to assess the three-way interaction between the two types of nutrient enrichment and thermal stress on coral health.

The UM Rosenstiel School research team published a previous study in 2015 that showed the critically endangered Staghorn coral may benefit from supplemental nutrition to mitigate the adverse impacts of global climate change. The results revealed that temperature, CO2 and feeding each had significant effects on the coral's growth rate. That study was the first to document that an endangered coral species, which was once found widely throughout South Florida and the Caribbean, can buffer the effects of increased CO2 in the ocean by increasing feeding rates.

"Excess nutrients from land sources and thermal stress will likely occur in concert in the future so it's important to assess them together," said Towle. "Incorporating nutrient levels in thermal bleaching models will likely be very important for coral reef managers in the future as ocean waters warm."

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

</div></figure>



Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Kainji Lake, a reservoir on the Niger River.



In 1968, Kainji Lake was created by the construction of the Kainji Dam. The Niger River, the third longest in Africa, enters the lake in the north.&nbsp;



According to <a href="https://www.earth.com/news/rivers-in-the-american-west-are-a-lifesaving-resource-for-birds/">ESA</a>, the creation of the lake submerged Foge Island and the town of Bussa and permanently flooded other riverine settlements, leaving around 50,000 people displaced.&nbsp;



Large parts of Foge Island are temporarily exposed during low water tides, and the land is often used by migrating fishermen. Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. 



Wild mammals occur at relatively low densities due to illegal hunting. Lake Kainji has suffered a dramatic decline as a fishery due to the high numbers of artisanal and subsistence fisherfolk using the lake. It has been suggested that a period of closure, together with controlled fishing rights may help improve fish stocks.



Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians.

Today’s Video of the Day from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.



“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. 



The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.



“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;



“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”



The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;



The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today’s Video of the Day from <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes why experts are studying zebrafish to gain a better understanding of how the immune system responds to injury. Zebrafish have the ability to repair and regenerate organs.



“Organ regeneration offers an exciting opportunity for studying the immune system and to inquire why some species can regenerate organs like the heart or missing limbs while others like humans cannot,” explained Dr. Tatjana Piotrowski.



Zebrafish sensory organ hair cells are an ideal system to investigate the pathways and cell types involved in regeneration since they are easily destroyed with antibiotics and begin regenerating within five hours. This enabled the researchers to identify the exact timing and genetic programs for each anti-inflammatory macrophage activation state.&nbsp;



“Our hypothesis is that human macrophages do not receive the proper chemical activation 'cocktail' to instruct pro-regenerative processes,” said Dr. Nicolas Denans. “Identifying the molecular recipe of macrophage activation in zebrafish may one day enable us to design regenerative immunotherapies in humans.”&nbsp;&nbsp;&nbsp;



“The new evidence is a valuable resource for comparative studies on the genetic programs involved in macrophage-mediated repair and regeneration. In other words, different types of injuries may induce different kinds of inflammatory responses. We want to decipher whether this 'language' is universal or if there are a variety of dialects."

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes how record-breaking heat expressed itself around the world in 2022.



Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.
