Do you recall those childhood days when you eagerly anticipated bedtime stories about Peter Rabbit, Toad or Ratty from The Wind in the Willows? Or the excitement that washed over you every time you opened a children's book teeming with playful, animated animals? 



Well, a new study is giving us a fresh perspective on the role of these furry, iconic characters.



<h2 class="wp-block-heading" id="h-children-s-books-animal-characters">Children's books animal characters</h2>



The research has shed light on the <a href="https://www.earth.com/news/toddlers-learn-faster-after-witnessing-impossible-events/" target="_blank" rel="noreferrer noopener">potential influence</a> of non-human characters in children's books.



The researchers aimed to gauge how these animal characters affected children's theory of mind skills - crucial abilities which include deciphering social changes in the environment based on voice tone, word choice, or facial expressions.



They worked with over 100 children aged five to 10, each of whom were tested on their theory of mind skills after hearing stories featuring animal characters, as well as those highlighting human characters.



<h2 class="wp-block-heading" id="h-human-vs-animal-characters-in-books">Human vs. animal characters in books</h2>



The study unveiled an interesting pattern. When exposed to stories centered around human characters, an age-related progression was observed. 



Older children were consistently outperforming their younger counterparts, with 3rd grade children surpassing the researchers' expectations in tests featuring human characters.



But the revelations didn't stop there. The tests that involved animal characters threw up another surprise. 



The younger participants were able to match the scores achieved by pupils in 3rd grade, who were two years their senior. That's quite a feat for our young champions.



<h2 class="wp-block-heading" id="h-new-insight-into-children-s-development">New insight into children's development</h2>



These findings, published in the Journal of Experimental Child Psychology, highlight the importance of both human and non-human characters in <a href="https://www.earth.com/news/outdoor-classes-improve-childrens-mental-health/" target="_blank" rel="noreferrer noopener">children's developmental stages</a>.



The research was led by Dr. Gray Atherton and Dr. Liam Cross from the University of Plymouth’s <a href="https://www.plymouth.ac.uk/schools/psychology" target="_blank" rel="noreferrer noopener">School of Psychology</a>.



"Animals play a huge part of children’s stories, whether that is in books and comics or through TV and film. We wanted to test if that is down to more than simply liking the characters, and whether there are actual benefits of children learning through by watching or reading about animals and if this changes over time," said Dr. Atherton.



"Our findings showed that both human and non-human characters are important in helping children interpret the world around them, and that they play differing roles at different stages in their development. Adapting activities and lessons in nurseries and the early school years to take that into account could be hugely effective in helping to support their development."



<h2 class="wp-block-heading" id="h-implications-for-educators-and-parents">Implications for educators and parents</h2>



The insights gained from this study have substantial implications for educators and parents aiming to support children's cognitive and social development.



By incorporating both human and animal characters into books, educators can craft a more balanced learning environment that caters to the diverse needs of children across age groups. 



Parents, too, can enrich their children's home learning experiences by selecting a variety of stories that include both human and animal protagonists. 



This approach not only makes reading sessions more engaging but also aids in developing empathy and understanding of complex social scenarios.



<h2 class="wp-block-heading" id="h-future-research-directions">Future research directions</h2>



While this study provides valuable insights, it also opens avenues for further exploration. 



Future research could go deeper into the types of animal characteristics that are most effective in nurturing children's theory of mind. For instance, exploring whether anthropomorphized animals or more realistic portrayals have differing <a href="https://www.earth.com/news/parents-who-use-humor-have-better-relationships-with-their-children/" target="_blank" rel="noreferrer noopener">impacts</a>. 



Similarly, cross-cultural studies could investigate whether the affinity towards animal characters holds true in diverse cultural contexts. These inquiries could refine understanding and application in educational strategies, enhancing the efficacy of storytelling as a developmental tool.



<h2 class="wp-block-heading" id="h-animal-characters-and-autism-treatment">Animal characters and autism treatment</h2>



In previous studies, Dr. Atherton and Dr. Cross examined the factors influencing the educational and social development of individuals with autism and learning difficulties.



The experts launched initiatives proving how board and online games can bolster confidence among people with autism. 



Borrowing insights from this research, the scholars now plan to dig deeper to explore if their findings could provide specific benefits to children with such conditions.



Dr. Cross envisions a significant impact of this study on individuals with autism or <a href="https://www.earth.com/news/kids-with-behavioral-issues-have-high-cortisol-levels-in-their-hair/" target="_blank" rel="noreferrer noopener">other conditions</a> affecting their learning. 



<h2 class="wp-block-heading" id="h-a-new-way-of-looking-at-animal-characters">A new way of looking at animal characters</h2>



The researchers have observed how tasks involving animal characters can result in autistic individuals performing on par with non-autistic children. 



The plan is to replicate this study with autistic children in an effort to unveil more effective ways to support them at a critical stage in their development.



In a nutshell, this study has unraveled an entirely new dimension of how we view animals in children's books. 



Those delightful animal characters do more than simply entertain; they help shape our children's minds and understanding of the world around them in their formative years.

Animal characters boost social and emotional skills in children

Do you recall those childhood days when you eagerly anticipated bedtime stories about Peter Rabbit, Toad or Ratty from The Wind in the Willows? Or the excitement that washed over you every time you opened a children's book teeming with playful, animated animals?

First study to show that deciduous tree water uptake of snowmelt water represents a large but overlooked aspect of the water cycle in boreal watersheds

Trees play a surprising role in the water cycle. Approximately 25 to 50 percent of a living tree is made up of water, depending on the species and time of year. The water stored in trees has previously been considered just a minor part of the water cycle, but a new study by University of <a href="https://www.bing.com/search?q=alaska+airlines&amp;form=EDGEAR&amp;qs=LS&amp;cvid=b01cd5804ef94428899d1a42beca17e1&amp;cc=US&amp;setlang=en-US&amp;elv=AY3%21uAY7tbNNZGZ2yiGNjfMa*3koim6WmYuhKqzXqmtQJDg%21TXLJQdKc8qulnPuP2HsXJk9wtd%21dGVLdCAsEDkO1klF6fuy1sFFvpS9JSyPj&amp;plvar=0&amp;PC=HCTS">Alaska</a> Fairbanks scientists shows otherwise.

Research published this week in Nature Scientific Reports is the first to show that the uptake of snowmelt water by deciduous trees represents a large and previously overlooked aspect of the water balance in boreal watersheds. The study was led by Jessica Young-Robertson, who worked with other scientists from the National Weather Service and UAF's International <a href="http://www.earth.com/news/antarctic-ice-loss-sea-level/">Arctic</a> Research Center and Geophysical Institute.Trees play a surprising role in the water cycle

The results are critical for understanding boreal forest hydrology and ecology, including soil moisture, the availability of freshwater, tree health and the ways trees influence regional weather, particularly thunderstorms. All of these factors are important for understanding the frequency and severity of wildland fires.

Like a straw, trees draw water up from the soil and eventually release it into the atmosphere through leaves or needles. The scientists measured the water content in both deciduous and evergreen trees in several locations at different times of the year.

They found that deciduous trees took up a surprisingly large amount of water in the period between snowmelt and leaf-out. These trees absorbed 21 to 25 percent of the available snowmelt water -- to the point of being completely saturated. For the boreal forest of Alaska and Western Canada, this equates to about 17-20 billion cubic meters of water per year. That is roughly equivalent to 8 million Olympic-sized swimming pools or 8-10 percent of the Yukon River's annual discharge.

The study also quantified transpiration -- the water that trees release to the atmosphere. The researchers found that deciduous trees transpired 2 to 12 percent of the absorbed snowmelt water immediately after leaf-out. This concentrated period of transpiration has the potential to create more favorable conditions for atmospheric convection and thunderstorms, which start many of the wildfires in the sparsely populated boreal forest region.

Calculating the amount of water stored by deciduous trees is important. The area occupied by deciduous trees in the boreal forest is expected to increase 1 to 15 percent by the end of this century, and the absorption of snowmelt could also then increase.

This is the first study to show that deciduous tree water uptake of snowmelt water represents a large but overlooked aspect of the water balance in boreal watersheds. Tree water dynamics impact many processes. Quantifying tree water storage is important for understanding hydrology, tree response to drought and the related factors of tree water use, soil moisture and climate.

Garden grass may soon be a source of clean energy. Researchers develop novel way of deriving hydrogen from grass using just sunlight and a cheap catalyst

Garden grass could become a source of cheap and clean renewable energy, scientists have claimed.

A team of UK researchers, including experts from Cardiff University's Cardiff Catalysis Institute, have shown that significant amounts of hydrogen can be unlocked from fescue grass with the help of sunlight and a cheap catalyst.

It is the first time that this method has been demonstrated and could potentially lead to a sustainable way of producing hydrogen, which has enormous potential in the renewable energy industry due to its high energy content and the fact that it does not release toxic or greenhouse gases when it is burnt.

Co-author of the study Professor Michael Bowker, from the Cardiff Catalysis Institute, said: "This really is a green source of energy.

"Hydrogen is seen as an important future energy carrier as the world moves from fossil fuels to renewable feedstocks, and our research has shown that even garden grass could be a good way of getting hold of it."

The team, which also includes researchers from Queen's University Belfast, have published their findings in the Royal Society journal Proceedings A.

<a href="http://www.earth.com/video/concentrating-sunlight-to-produce-clean-hydrogen/">Hydrogen</a> is contained in enormous quantities all over in the world in water, hydrocarbons and other organic matter.

Up until now, the challenge for researchers has been devising ways of unlocking hydrogen from these sources in a cheap, efficient and sustainable way.

A promising source of hydrogen is the organic compound cellulose, which is a key component of plants and the most abundant biopolymer on Earth.

In their study, the team investigated the possibility of converting cellulose into hydrogen using sunlight and a simple catalyst -- a substance which speeds up a chemical reaction without getting used up.

This process is called photoreforming or photocatalysis and involves the sunlight activating the catalyst which then gets to work on converting cellulose and water into hydrogen. The researchers studied the effectiveness of three metal-based catalysts -- Palladium, Gold and Nickel.

Nickel was of particular interest to the researchers, from a practical point of view, as it is a much more earth-abundant metal than the precious metals, and is more economical.

In the first round of experiments, the researchers combined the three catalysts with cellulose in a round bottom flask and subjected the mixture to light from a desk lamp. At 30 minutes intervals the researchers collected gas samples from the mixture and analysed it to see how much hydrogen was being produced.

To test the practical applications of this reaction, the researchers repeated the experiment with fescue grass, which was obtained from a domestic garden.

Professor Michael Bowker continued: "Up until recently, the production of hydrogen from cellulose by means of photocatalysis has not been extensively studied.

"Our results show that significant amounts of hydrogen can be produced using this method with the help of a bit of sunlight and a cheap catalyst.

"Furthermore, we've demonstrated the effectiveness of the process using real grass taken from a garden. To the best of our knowledge, this is the first time that this kind of raw biomass has been used to produce hydrogen in this way. This is significant as it avoids the need to separate and purify cellulose from a sample, which can be both arduous and costly."

Scientists: Humanity is lucky climate change didn't start sooner. There is some consolation in how the fossil fuel-induced climatic changes we increasingly experience through droughts and storm surges are playing out. It could have happened sooner, and therefore already have been much worse.

Luckily, the natural atmosphere already contained carbon dioxide, enough that the human-induced changes were relatively small, for a long time. Had these concentrations been even slightly lower, the effects of the emission of harmful greenhouse gases would have been felt much earlier, at a time when mankind was not yet ready or knowledgeable enough to face up to mitigation efforts. This silver lining approach is taken by David Archer of the University of<a href="http://www.earth.com/news/chicago-named-wild-onion/"> Chicago</a> in the US, in a scenario exercise in Springer's journal Climatic Change.

The concentration of carbon dioxide molecules in the atmosphere is measured as parts per million of dry air, or ppm. In the climatic past and earlier glacial periods, this level fluctuated between 180 ppm and 260 ppm. Measurements taken of <a href="https://en.wikipedia.org/wiki/Antarctica">Antarctic</a> sheet ice show that the concentration of naturally occurring carbon dioxide in the atmosphere was already 278 ppm in the 1750s before industrialization started in earnest.

"If the initial atmospheric carbon dioxide concentration were half its actual value, we would currently be experiencing the climate expected for the year 2050," says Archer, setting out one possible scenario. "If there were only one-tenth as much carbon dioxide in the atmosphere initially, the climate forcing we are experiencing today would have already happened, in the year 1900."

Archer therefore describes the climatic changes currently being experienced on Earth as "moderate," thanks to the blanketing effect that naturally occurring carbon dioxide in the atmosphere has had. This has given scientists the time to piece together an understanding of Earth's climate system and the effects of fossil fuel emissions.

The first ideas about radiative balance and the greenhouse effect date back to 1827, while predictions about climatic sensitivity due to carbon dioxide were made by 1896. It was, however, only after the advent of the computer that a modern understanding emerged of how fossil fuel use would impact the climate. This understanding was able to mature to the extent of public warnings about it by the 1970s.

"If the natural concentration had been a factor of two or more lower, the climate impacts of fossil fuel carbon dioxide release would have occurred about 50 or more years sooner, making it much more challenging for the developing human society to scientifically understand the phenomenon of manmade climate change in time to prevent it," he says. "To the extent that a thorough scientific understanding is also a requisite for making a decision to abandon fossil fuels, the outlook for humanity would have been considerably darker in this altered world than it has turned out in actuality."

Merciless heat wave covers the US. Call it the United Sweats of<a href="http://www.earth.com/image/deforestation-south-america/"> America</a>. A heat wave spreading across the country is leaving few places to hide. Not even the cool of night.
By Friday afternoon, all but one of the Lower 48 states had hit 90 degrees somewhere, with only Washington around for cooler comfort. For much of the country, it was expected to get even worse over the weekend.
"It's just day after day. Merciless," said Jeff Masters, meteorology director of the private Weather Underground. "We don't often see this much of the country this hot for this length of time."
And while the extra hot weather will ease a bit next week for good chunks of the country, the temperature forecast for the next three months isn't exactly promising, according to the National Oceanic and Atmospheric Administration.
For the first time in more than 20 years, the Climate Prediction Center<a href="http://www.cpc.ncep.noaa.gov/products/predictions/long-range/lead01/off01-temp.gif">map</a> is shades of one color: orange for above normal temperatures.
The map usually varies, showing places where there is a greater chance for above or below normal temperatures or equal chances. But the outlook for August, September and October is for above normal everywhere.
Center climate scientist Dan Collins said the center's archives go back to 1995 and they've never seen this for the entire United States - including Alaska and Hawaii. That doesn't mean a three-month heat wave, just on average warmer than normal temperatures through October.
"Unusual indeed," Collins said. "But maybe less so as the years pass."
Scientists haven't calculated if man-made global warming from the burning of fossil fuels is a factor in the current heat wave, but said it has been a factor in most recent ones and a good chance here, too.
What's happening now is a ridge of high pressure has just spread over almost the entire United States. That keeps clouds and cooling away, and just pushes warm air down.
Add to that the humidity, which makes everything feel stickier. It's coming with warmer ocean water, especially from a hotter-than-normal <a href="https://www.bing.com/search?q=gulf+of+mexico&amp;form=EDGEAR&amp;qs=PF&amp;cvid=2c03b5946f1b4c878cc3a06f65c57746&amp;cc=US&amp;setlang=en-US&amp;elv=AY3%21uAY7tbNNZGZ2yiGNjfNhS3t*LItEfHefM2goi1CZbtqxB8iRhXDpyzoxrjsjGc5ydP2RzZzbZRZgKw*U*RpxqfDQQMPHzoMJKWmo%211rY&amp;plvar=0&amp;PC=HCTS">Gulf of Mexico</a>, Masters said.
The high heat and humidity will move from the Corn Belt toward the Southeast over the weekend, according to the National Weather Service.
On Monday, the weather service forecasts that nearly all of the Lower 48 states could hit 95 on the <a href="http://www.wpc.ncep.noaa.gov/heat-index-MAX/bchi-day3.html">heat index</a> , which factors in humidity. And about 30 states are forecast to hit 100.
The high temperature averaged for the Lower 48 states was 92 degrees on both Thursday and Friday, the warmest since June of 2012, said meteorologist Ryan Maue of the private WeatherBell Analytics service.
Not even the cool of night is helping because temperatures aren't dropping as much as they normally do. That's a health issue because the human body relies on the evening coolness for relief, said Greg Carbin, a forecast chief for the weather service's Weather Prediction Center.
Heat waves like this one "are kinda like the home run statistic in steroid-fueled baseball," University of Georgia meteorology professor Marshall Shepherd said in an email. "Sure heat waves always happened naturally (like home runs in baseball) but the statistics are shifting to make them more likely and more frequent within a warmer background climate."

NASA: Historical records not an accurate prediction of climate change. A new <a href="https://en.wikipedia.org/wiki/NASA">NASA</a>-led study finds that almost one-fifth of the global warming that has occurred in the past 150 years has been missed by historical records due to quirks in how global temperatures were recorded. The study explains why projections of future climate based solely on historical records estimate lower rates of warming than predictions from climate models.

The study applied the quirks in the historical records to climate model output and then performed the same calculations on both the models and the observations to make the first true apples-to-apples comparison of warming rates. With this modification, the models and observations largely agree on expected near-term global warming. The results were published in the journal Nature Climate Change. Mark Richardson of NASA's Jet Propulsion Laboratory, Pasadena, <a href="http://www.earth.com/image/shasta-lake-northern-california/">California,</a> is the lead author.

The Arctic is warming faster than the rest of Earth, but there are fewer historic temperature readings from there than from lower latitudes because it is so inaccessible. A data set with fewer Arctic temperature measurements naturally shows less warming than a climate model that fully represents the Arctic.NASA: Historical records not an accurate prediction of climate change

Because it isn't possible to add more measurements from the past, the researchers instead set up the climate models to mimic the limited coverage in the historical records.

The new study also accounted for two other issues. First, the historical data mix air and water temperatures, whereas model results refer to air temperatures only. This quirk also skews the historical record toward the cool side, because water warms less than air. The final issue is that there was considerably more Arctic sea ice when temperature records began in the 1860s, and early observers recorded air temperatures over nearby land areas for the sea-ice-covered regions. As the ice melted, later observers switched to water temperatures instead. That also pushed down the reported temperature change.

Scientists have known about these quirks for some time, but this is the first study to calculate their impact. "They're quite small on their own, but they add up in the same direction," Richardson said. "We were surprised that they added up to such a big effect."

These quirks hide around 19 percent of global air-temperature warming since the 1860s. That's enough that calculations generated from historical records alone were cooler than about 90 percent of the results from the climate models that the Intergovernmental Panel on Climate Change (IPCC) uses for its authoritative assessment reports. In the apples-to-apples comparison, the historical temperature calculation was close to the middle of the range of calculations from the IPCC's suite of models.

Any research that compares modeled and observed long-term temperature records could suffer from the same problems, Richardson said. "Researchers should be clear about how they use temperature records, to make sure that comparisons are fair. It had seemed like real-world data hinted that future global warming would be a bit less than models said. This mostly disappears in a fair comparison."

NASA uses the vantage point of space to increase our understanding of our home planet, improve lives and safeguard our future. NASA develops new ways to observe and study Earth's interconnected natural systems with long-term data records. The agency freely shares this unique knowledge and works with institutions around the world to gain new insights into how our planet is changing.

Woody climbing vines, known as lianas, are preventing tropical forests from recovering and are hampering the ability of forests to store carbon, scientists are warning

Woody climbing vines are threatening tropical forests. Instead of taking decades to recover, tropical forests are at risk of taking hundreds of years to re-grow because of lianas, which spread rapidly following extensive tree-felling.

In a new study published in the African Journal of Ecology, scientists advocate the temporary removal of lianas in selected areas to help tropical forests grow back.

The team, from the University of York and Flamingo Land zoo, reveal for the first time outside of commercial forestry or plantation studies, how lianas are preventing the growth of trees in an African forest.

This observation was not a huge surprise based on previous work elsewhere in the tropics and its established use in forestry.

However, the scientists also reviewed previous scattered studies and have revealed that the impact on tree growth rates is approximately equivalent across the tropics, on average nearly halving the rate of growth. Also Woody climbing vines are threatening tropical forests causing a lot more problems that anticipated.

More sparse data even suggests a net 7-fold decrease in the overall rate of biomass accumulation (accounting for tree mortality and the growth of new trees).

"The implications for the global carbon sink are profound," said Dr Andrew Marshall from the University's Environment Department and Director of Conservation Science at Flamingo Land.

"No-one has until now compiled data from all over the world to see what the general trend is. What this study suggests is a trend; that lianas are impacting on the tropics but not just in selected sites."

However, Dr Marshall says the lianas also help to promote <a href="http://www.earth.com/news/biodiversity-offsetting-may-be-limited-by-land-constraints/">biodiversity</a> and help sustain an abundance of plants and animals -- creating "bridges" across the trees, food for monkeys and other animals, and generally adding to the overall function of forests.

In the paper, the scientists highlight one climber, known locally as "the lion's grasp", because of its claw-like spines.

Dr Marshall said the problem had been caused by commercial logging, which allowed the lianas to flourish.

"We don't want to advocate taking all the lianas out of the forest, that would be terrible. But a temporary removal in some places will help forests grow back," Dr Marshall added.

"Lianas are an important part of the ecology. If we temporarily cut them back the trees start growing more, with new trees sprouting and less mortality, resulting in more and more biomass in the forest."

"We don't have enough data yet to know which species respond well to clearing out lianas, that is the next stage in the research."

Iron mine orchids

Millions of orchids are now growing in a hundred-acre wetland in the Adirondack Park that developed on waste from a vast open-pit iron mine, a transformation scientists say is most impressive because it happened naturally. Old iron mine now covered with millions of orchids
"It's a testament to nature's ability to heal itself," said Grete Bader, a graduate student who recently wrote her master's thesis about the plant life at the former Benson Mines, about 35 miles from the <a href="https://en.wikipedia.org/wiki/Canada">Canadian</a> border. Old iron mine now covered with millions of orchids
The wetland, which remains privately owned and off limits to the public, formed on part of thousands of acres of coarse sand left over when granite ore was crushed to extract iron from 1900 until 1978. That bare sand eventually gave way to moss, lichen, grasses, sedges and trees, including willows, poplars and tamaracks.


[caption id="attachment_2405221" align="alignleft" width="150"]<img class="size-thumbnail wp-image-2405221" src="http://cff1.greenatom.earth/uploads/2016/07/23103325/flower-pink-orchid_1big_ap-150x150.jpg" alt="A grass pink orchid is seen where waste from a former iron mine" width="150" height="150" /> A grass pink orchid is seen where waste from a former iron mine[/caption]
Orchids arrived as dust-like seeds from surrounding areas. The wetland is now home to six species of bog orchids, including millions of rose pogonias and grass pinks.
"I've been involved in orchid-rich habitats all over the country for 40 years, and I've never seen anything like this," said Donald Leopold, a professor at the State University of New York College of Environmental Science and Forestry.
Leopold first explored the site 30 years ago, but the staggering number of orchids wasn't quantified until recently when his graduate student, Bader, tallied them up in her thesis.
Several factors contribute to the thriving plant community at the site, Bader said, including a variety of fungi that colonize a plant's root system and enhance its ability to absorb nutrients.
"What's really cool to me as a plant ecologist is how this site went from bare mine tailings to a diverse wetland plant community over the past 60 years on its own, without any formal restoration initiative," Bader said during a recent visit to the site.

Bader and Leopold suggest that the site would be a worthy addition to the Adirondack Forest Preserve if the owner was interested in selling it to the state.
But the landowner's lawyer says there are no plans to sell the land or allow public access. "Benson Mines wasn't even aware of the orchids until the researchers made them public," said attorney Bernard Melewski.
He said the orchid site is a small part of about 2,000 acres of sand and crushed stone mining waste that the company hopes to ship to markets when a nearby railroad spur is renovated.
Even if the site remains untouched by development, the orchids may be a fleeting phenomenon as the natural forces that brought them here continue to reshape the landscape. Already, an aggressive non-native reed called phragmites is choking out other plants in large swaths of the wetland.
"The orchids here today require full sun," Bader said. "Between invasive plants and natural succession to a closed canopy tamarack-black spruce bog, we're going to see them decline."

A solar energy project has some environmentalists seeing red.
Solar energy ordinarily wins praise from groups that want to cut greenhouse gases, but a proposed solar project at a defunct Long Island nuclear power plant has stirred outrage because it requires demolishing 350 acres of woodlands. Solar energy project in Long Island is angering environmentalists
"Choosing solar over forests anywhere in the world is just plain stupid," said Dick Amper, of the Long Island Pine Barrens Society. "Solar is very important to fight global warming and beyond, but I'm afraid we're making false choices when you destroy portions of nature and the environment to accomplish that end." Solar energy project in Long Island is angering environmentalists
Similar projects are happening elsewhere.
A court fight is brewing over a plan by<a href="http://www.earth.com/news/new-jersey-wild-animal-traveling-performances/"> New Jersey'</a>s Six Flags Great Adventure amusement park to cut down nearly 15,000 trees to make way for a solar farm. In Connecticut, state officials recently approved a plan to raze 134 acres of trees in the town of Sprague, near Norwich, for a solar energy project.
Alex Hobson, a spokeswoman for a Solar Energy industry group in Washington, D.C., declined to comment on the Long Island proposal, but said the industry "is committed to responsible use of the land on which we operate and we go to great lengths to protect biodiversity and ecologically fragile lands."
Under the proposal, a company called LI Solar Generation, LLC, a joint venture between NextEra Energy Resources and National Grid, would construct the facility on the grounds of the defunct Shoreham nuclear power plant.
The plant was completed in 1984 for $6 billion but never opened because of community opposition over potential safety concerns. The solar project backers are hoping to plug into existing electric energy infrastructure on the Shoreham property, with plans for up to 72 megawatts of solar energy, providing power for more than 13,000 homes.
A part of the plan mentions replanting trees elsewhere to offset the cutting of the forest but a spokesman for the company did not have details.
Walter Thomas, who teaches a course on solar energy at the University of Massachusetts-Lowell, questioned why it was necessary to eliminate any trees at all.
"I would think Long Island would have giant rooftops and parking lots in shopping malls that could be used for large solar projects if that's what's needed," Thomas said. "There's so much acreage available for that stuff."
Sid Bail, president of the Wading River Civic Association, who lives about a half mile from the Shoreham site along the Long Island Sound, isn't buying it. "I favor renewable energy, but in this case it's a very bad trade-off," he said.
The proposal submitted last month still requires extensive regulatory review.
"We are prepared to work closely with all public officials and the local community to come up with the best solution to have renewable solar energy at Shoreham, and preserve as much of the property as possible," Ross Groffman, executive director of NextEra Energy Resources and LI Solar Generation said in a statement.
Neal Lewis, executive director of the Sustainability Institute at Molloy College, an environmental advocacy group on Long Island that supports the Shoreham project, said it is always preferable to build solar projects in open spaces that don't require the elimination of large numbers of trees. But he notes that "of all the potential options, there is nothing less impactful on the environment than putting in a solar farm."
"That's the real world we live in and they have a right to develop it."

More than 1,000 people joined Hollywood stars for a climate rally, including Shailene Woodley, Susan Sarandon and Danny Glover in <a href="https://www.bing.com/travelguide?q=Philadelphia&amp;l2sid=020d4bbf-2971-4236-b87d-c3ec1d7f851c&amp;form=PLACAB">Philadelphia</a> last night on the eve of the Democratic National Convention and vowed to keep fighting for climate and environmental justice issues, even though their preferred presidential candidate would not be driving the party's agenda.
Sarandon, who like the other stars in attendance campaigned on behalf of Sen. Bernie Sanders, said the rally's turnout was proof that theirs was a movement and not a cult of personality as some critics alleged.
"Our commitment hasn't ended. This is not just about one election. ... We want real progressive politics and we want to say thank you to Bernie for igniting this spark," she said. "Now we're awake and we have to stay awake."Hollywood stars hold a climate rally
Many in the crowd, which one speaker described as a group of "climate justice activists, fracktivists and climate revolutionaries," wore Sanders shirts, buttons or lanyards. Some carried signs like, "Bernie would end fracking," and the now defunct "Bernie for President."Hollywood stars hold a climate rally
There was little mention of presumptive Democratic nominee Hillary Clinton with only one speaker making unfavorable comparisons between Sanders and Clinton while proudly noting that "we took over the <a href="http://www.earth.com/news/democracy-better-health-nations/">Democratic</a> party." Another drew shouts and applause when he said a happy goodbye to Democratic National Committee Chairwoman Debbie Wasserman Schultz, who is resigning.
There was also little talk of Republican presidential nominee Donald Trump, although one speaker did refer to him as a fascist.
The event was organized by NextGen Climate, a San Francisco-based environmental advocacy organization. The event included musical acts and a screening of the documentary "How to Let Go of the World and Love All the Things Climate Can't Change" by writer/director Josh Fox. Fox is best known for "Gasland," which included memorable images of Pennsylvania homeowners setting tap water aflame.
Woodley urged the crowd to let go of anger and ego that could lead to violence.
"If you show up with love and solidarity to those around you, that sparks great change," she said.
Glover had a similar message, noting there was a long fight ahead.
"This is a permanent revolution," he said. "This is not about this election. That's too small. That's not enough for us."
The convention officially starts Monday, with Clinton expected to accept the party's nomination on Thursday.

Drought hits the Northeastern US. At Lavoie's Farm in New Hampshire, beans and corn haven't broken through the ground yet and fields of strawberries are stunted.

The drought that has taken hold in the Northeast is especially felt at John Lavoie's farm in Hollis, presenting him with some tough choices. Irrigation ponds are drying up, forcing him to choose between tomatoes and berries or apple and peach trees.

Lavoie decided to hold off watering the fruit trees so he could quench the tomato and berry plants before they succumb to the heat.

"We need some rain pretty quick," Lavoie said. "There is just some corn that won't make it. A lot of things we would like to give water to, we can't."

The dry blast in New Hampshire is being felt throughout the Northeast, from Maine to Pennsylvania, driven by a second year of below-average rainfall. Though not as dire as the West Coast drought of five-years running, the dry, hot weather has stressed farms and gardens, prompted water restrictions and bans in many towns and threatened to bring more wildfires than usual.

<img class="alignleft size-thumbnail wp-image-2405263" src="http://cff1.greenatom.earth/uploads/2016/07/25091337/drought-farm-northeastern-us_2big_ap-150x150.jpg" alt="drought-farm-northeastern-us_2big_ap" width="150" height="150" />In the hardest hit areas of western <a href="http://www.earth.com/news/climate-change-2080-new-york-arkansas/">New York</a>, Massachusetts and southern parts of New Hampshire and Maine, it's been dryer than in a decade or more. And national weather experts predict the drought will persist at least through the end of October.

"The Northeast is a little bit of a mixed bag, but the bottom line is that the conditions have deteriorated over the past several weeks to a couple of months," said Rich Tinker, a drought specialist at the National Oceanic and Atmospheric Administration.

If there were a drought epicenter, it probably would be Massachusetts. More than 74 percent of the state, according to the <a href="https://www.bing.com/search?q=united+states&amp;FORM=EDGENA&amp;PC=HCTS&amp;refig=adb76a30e2504c9ef94f0fed7fe4b9fd">United States</a> Drought Monitor, is experiencing some degree of drought and almost the entire state is dry.

Many Massachusetts farmers are hurting, said Katie Campbell-Nelson, a vegetable production specialist with the UMass Extension. Yields and quality are down, and irrigation costs are up.

"Some farmers are abandoning crops because it's not worth the financial risk of harvesting them," Campbell-Nelson said.

The dry conditions have raised the risk of wildfires in Massachusetts, said Dave Celino, chief forest fire warden for the state Department of Conservation and Recreation. Typically, the state records about 1,600 wildland fires a year. But this year, it's already seen more than 1,000.

Meanwhile, some wells are going dry in Connecticut. And the blueberry crop in Maine will be slightly smaller this year than the past two, said Nancy McBrady, executive director of the Wild Blueberry Commission of Maine.

In New Hampshire, the Lavoies, like their farming neighbors, are spending twice as much and committing 90 percent of their labor to watering. They've instituted drip agriculture and other conservation measures to ensure every drop of water goes farther and lasts longer. It's a smart move, especially since it may be months before they see any relief.

<div class="img-wrapper">Two tropical cyclones in the Eastern Pacific Ocean have see-sawed in strength today, July 26, 2016. Tropical Storm Georgette and Hurricane Frank see-saw in strength</div>
Infrared satellite imagery from <a href="https://en.wikipedia.org/wiki/NASA">NASA'</a>s Aqua satellite showed colder cloud top temperatures in Frank today as it became a hurricane and warming temperatures in Georgette as it weakened from a <a href="http://www.earth.com/news/future-hurricanes-wetter-and-windier/">hurricane</a> to a tropical storm. The infrared data, taken July 26 at 0959 UTC (5:59 a.m. EDT) showed a much smaller Tropical Storm Georgette in comparison to the now hurricane, Frank.

At 11 a.m. EDT (1500 UTC) on July 26, 2016, the center of Tropical Storm Georgette was located near latitude 18.4 North, longitude 128.6 West. Georgette is moving toward the northwest near 3 mph (6 kph). A motion toward the northwest with some increase in forward speed is expected during the next couple of days. Maximum sustained winds have decreased to near 70 mph (110 kph) with higher gusts.

The National Hurricane Center noted that additional weakening is forecast during the next 48 hours, and Georgette could degenerate to a remnant low pressure area by Thursday, July 28. Tropical Storm Georgette and Hurricane Frank see-saw in strength

Feds: Airliners are contributing greatly to climate change. The government has found that jet engine exhaust is adding to climate change and endangering human health, and needs to be regulated. Feds: Airliners are contributing greatly to climate change
The Environmental Protection Agency announced Monday that it will use its authority under the Clean Air Act to impose limits on aircraft emissions.
Jet engines spew significant amounts of greenhouse gases, including carbon dioxide and methane, into the upper atmosphere, where they trap heat from the sun. But proposed rules such as imposing fuel-efficiency standards have faced stiff opposition from aircraft makers and commercial airlines.
Aircraft emissions were not addressed as part of the landmark global climate agreement agreed to in <a href="https://www.bing.com/travelguide?q=Paris&amp;l2sid=85584d24-2116-5b98-89f9-5714db931ac6&amp;form=PLACAB">Paris</a> in December.
"Addressing pollution from aircraft is an important element of U.S. efforts to address climate change," said Janet McCabe, EPA's acting assistant administrator for air and radiation. She said aircraft are the third largest contributor to greenhouse gas emissions in the U.S. transportation sector, and that is expected to increase. Cars and trucks already are regulated.
The EPA's findings do not apply to small piston-engine planes or to military aircraft.
A U.N. panel in February recommended new emissions standards for international flights that require an average 4 percent reduction in fuel consumption during the cruising phase of flight. The new regulations from the International Civil Aviation Organization require that new aircraft designs meet the standards beginning in 2020, and that designs already in production comply by 2023.
Environmental groups have criticized the new international standards as too weak to actually slow global warming. Planes burn the most fuel during takeoffs and landings, while cruising at high altitudes is the most fuel-efficient period.
Environmentalists say aviation accounts for about 5 percent of global greenhouse emissions, though the U.N. and EPA cite studies concluding it's actually less than 2 percent.
The EPA finding announced Monday is expected to result in similar limits on domestic carriers, which critics say is long overdue.
"People should not have to choose between mobility and a healthy climate," said Marcie Keever, legal director for the environmental group Friends of the Earth. "The EPA's nine-year delay on regulating aircraft emissions failed the American people. Now it's time for the Obama administration to issue a strong rule, to hold the aviation industry accountable."

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;

'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."



"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east. A tiny part of Argentina is visible in the top-right corner of the image where the mountain crest of the Andes Mountains acts as a divider between the two countries," says ESA.

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 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."

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;

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.
