Have you ever found yourself in a quandary about whether children should use their fingers to count? If you have, you're not alone. Many preschool teachers are in the same boat. 



Some believe that little ones who resort to finger counting are struggling with math. Others see it as a clear sign of advanced numerical knowledge. 



One of the lead researchers for this study is Dr. Catherine Thevenot from the Institute of Psychology at the <a href="https://www.unil.ch/central/en/home.html" target="_blank" rel="noreferrer noopener">University of Lausanne</a>. 



Her team decided to investigate if a finger counting strategy could give a leg up to kindergarten-aged children when faced with arithmetic problems.



<h2 class="wp-block-heading" id="h-impact-of-finger-counting-on-kids">Impact of finger counting on kids</h2>



The experiment, which involved 328 five and six-year-olds (mainly white European kids living in France), set out to determine if children who don’t ordinarily count on their fingers could be trained to do so. And more importantly, it sought to find out if this training would improve their arithmetic abilities.



The process was straight-forward. Recruited through their teachers, the <a href="https://www.earth.com/news/kids-with-too-much-screen-time-struggle-to-gain-language-skills/" target="_blank" rel="noreferrer noopener">children</a> underwent a pre-test, a two-week training period, a post-test right after the training, and a delayed post-test.



The children who were trained and did not originally count on their fingers showed a substantial improvement in performance (from 37% to 77% of correct responses), outperforming those in the control group.



We now have the first study to prove that a <a href="https://www.earth.com/news/board-games-help-children-improve-their-math-skills/" target="_blank" rel="noreferrer noopener">child's arithmetic performance</a> can be boosted by teaching them a finger counting strategy.



<h2 class="wp-block-heading" id="h-crunching-numbers-with-dr-thevenot">Crunching numbers with Dr. Thevenot</h2>



As it turns out, the catalyst for this research was a question that kept cropping up during her interactions with primary school teachers -- should they encourage or discourage their pupils to count on their fingers? The lack of a clear answer in existing research prompted her to investigate the issue.



"Our findings are highly valuable because, for the first time, we provide a concrete answer to the long-standing question of whether teachers should explicitly teach children to use their fingers for solving addition problems -- especially those who don’t do so naturally. The answer is yes," Dr Thevenot said.



"Our study demonstrates that finger calculation training is effective for over 75% of kindergartners. The next step is to explore how we can support the remaining 25% of children who didn’t respond as well to the intervention." 



<h2 class="wp-block-heading" id="h-benefits-of-finger-counting">Benefits of finger counting</h2>



"When I first saw the results, I was amazed by the huge improvement in performance among children who didn’t initially use their fingers to solve the problems. Before our intervention, these children were only able to solve about one-third of the addition problems at pre-test," Dr. Thevenot said.



"After training, however, they were solving over three-quarters of them! The difference was striking, especially compared to the control groups, where gains were insignificant. The extent of this improvement truly exceeded my expectations," she concluded.



<h2 class="wp-block-heading" id="h-broader-implications-for-education">Broader implications for education</h2>



The insights gleaned from this study could have far-reaching implications for educational practices. 



By allowing children, particularly those who might initially struggle with arithmetic, the freedom to employ finger counting, educators can foster an environment that is both supportive and conducive to learning. 



This study challenges the traditional pedagogical stance that views finger counting as a crutch indicative of mathematical deficiency. 



Instead, it paints finger counting as a valuable tool that can enhance a child's comprehension of numbers and arithmetic processes, potentially leading to more effective teaching strategies that embrace individual learning styles.



<h2 class="wp-block-heading" id="h-what-s-comes-next">What's comes next?</h2>



What does the future hold? Well, they are now probing if the children have gained a deeper understanding of numbers or are simply following a procedure to solve problems. 



Initial results are promising according to Dr. Thevenot, but more tests are required for confirmation.



The study by Dr. Thevenot and her team opens several avenues for further investigation. Future research could explore the long-term impacts of finger counting as a foundational skill integrated into early mathematics education. 



Additionally, examining how cultural differences affect the perception and utilization of finger counting in various educational systems can provide a more comprehensive understanding of its benefits and limitations. 



Importantly, expanding the demographics beyond the initial cohort to include diverse populations will enhance the generalizability of the findings. 



<h2 class="wp-block-heading" id="h-a-show-of-hands">A show of hands</h2>



To sum it up, it seems that finger counting could be instrumental in reducing disparity in mathematics among children. 



So, the next time you see a <a href="https://www.earth.com/news/kindergarten-conduct-childhood-behavioral-problems-will-cost-society-later/" target="_blank" rel="noreferrer noopener">child</a> using their ten tiny tools to solve a math problem, remember, they might just be on to something. And, who knows? Maybe we adults could pick up a thing or two from those little fingers.

Finger counting boosts math skills in children

Have you ever found yourself in a quandary about whether children should use their fingers to count? If you have, you're not alone. Many preschool teachers are in the same boat. Some believe that little ones who resort to finger counting are struggling with math. Others see it as a clear sign of advanced numerical knowledge.

<div class="img-wrapper">Unexpected complexity in coral reefs complicates restoration efforts. Coral reefs are delicate ecosystems, which are endangered by climate change and human activities. The restoration of these underwater environments is typically carried out by transplanting corals from healthy reefs to compromised ones. This practice can be problematic, as it overlooks the local characteristics of each reef, and may reduce genetic diversity.</div>
The first step towards an ecologically mindful restoration is the detailed understanding of the population structure and genetic variation of each reef. Yuna Zayasu and Chuya Shinzato, from the Marine Genomics Unit of the Okinawa Institute of Science and Technology Graduate University (OIST), investigated 298 colonies from 15 locations across the Nansei Archipelago, in <a href="http://www.earth.com/news/nearly-complete-duck-billed-dinosaur-fossil/">Japan</a>. They compared the DNA of one of the most widespread coral, scientifically known as Acropora tenuis, to gain a deeper comprehension of its genetic diversity. Their project was a collaboration between several institutions: the Japanese Fisheries Research Agency, the University of the Ryukyus, OIST Marine Biophysics Unit and the OIST Marine Genomics Unit. Their results are published in Ecology and Evolution.

"We wanted to check the genetic correlation between different colonies," Zayasu explained. The researchers used a technique similar to the one commonly employed for paternity test, comparing 13 DNA portions for each different sample of the coral. Such portions are called 'microsatellites'. "The results show that there are at least two different populations of A. tenuis in the Nansei, despite the fact that there is no geographic boundary between these populations." Also the Unexpected complexity in coral reefs complicates restoration efforts causing a lot more harm than expected.

[caption id="attachment_2410504" align="alignleft" width="150"]<img class="size-thumbnail wp-image-2410504" src="http://cff1.greenatom.earth/uploads/2016/08/17101214/cff1.greenatom.earthuploads20160817101211media.eurekalert.orgmultimedia_prodpubweb122019_web-27dce3dc8a4abc18c7d297664527be9547acc776-50dc84b3b00c254ae34595c876a06b843f76399a-150x150.jpg" alt="coral Acropora tenuis" width="150" height="150" /> coral Acropora tenuis[/caption]

The finding is particularly interesting, because it questions the previous assumption that A. tenuis has the ability to easily disperse throughout the Nansei islands. This assumption was based on the importance attributed to the main marine current in the Nansei - the Kuroshio Current - in the life cycle of the coral. Specifically, on the influence that the Kuroshio could have while the coral is in its larva form, swimming to select a settlement site.

Zayasu and colleagues are suggesting that there are other factors that are key to explain the complex population structure. Specifically, a local current - ignored in coral studies to date - that flows in the opposite direction of the Kuroshio. This new hypothesis is supported by the fact that the Kuroshio Current flows from south to north, while one of the A. tenuis population shows signs of north to south expansion. The south of Okinawa Island is the potential contact point of the two populations.

"While we have clearly detected two populations, it is possible that there are more," Zayasu said. "Whole genome analysis - that allows full access to the <a href="https://en.wikipedia.org/wiki/NASA">DNA</a> of an organism - could in the future reveal more detailed population relationship, possibly even highlighting historical events such as local extinction and recovery."

The uniqueness of the coral reef that this study presents is noteworthy, because if each reef is a distinctive environment for unique varieties of corals, reef restoration should aim to protect the specific characteristics of each local habitat and population.

Also Western communities are facing effects of a warming climate with slower and earlier snowmelt reducing streamflows and possibly the amount of water reaching reservoirs used for drinking water and agriculture, according to a study published in July.</div>
"As the climate warms, there is actually a slower snowmelt - both in timing and rates, which makes for a less efficient streamflow," Adrian Harpold, ecohydrologist at the University of Nevada, Reno said. Harpold, who initiated the study two years ago at the University of <a href="http://www.earth.com/organizations/environment-colorado/">Colorado</a> Boulder, is a co-author of the paper published in AGU publications Geophysical Research Letters.

"I know, it's counterintuitive, but with a warming climate snowmelt starts sooner in the season, and at a slower rate because the warming occurs earlier when days are shorter and we have less sunlight," he said. "What makes runoff less efficient is that slower snowmelt reduces the amount of moisture being pushed deep into the subsurface where it is less likely to evaporate" Slower snowmelt reduces available drinking water also causing  a lot more damage for the agriculture too.

Higher snow melt rates can develop a pressure gradient that forces moisture deeper into the ground. With lower snow melt rates less water leaves the subsurface where the root systems of trees, bushes and grasses can access the water, which increases the amount of evapotranspiration into the atmosphere.

"It's ubiquitous in the western U.S.; the trends are consistent to all mountain ranges across the West," Harpold said.

Harpold, who's Nevada Mountain Ecohydrology Lab is based in the College of Agriculture, Biotechnology and Natural Resources, continued to work with the team from CU Boulder after coming to the University of Nevada, Reno.

The researchers used an exclusive modeling system to study the effects of slower snowmelt across various regions of the western United States including the Cascade range, the Sierra Nevada range, the Wasatch range and the Rocky Mountains. All of these areas see significant seasonal snow accumulation and generate water resources for downstream communities.

"Theo did the heavy lifting with the interpretation of the results and the writing of the paper," Harpold said of lead author of the study Theodore Barnhart, a graduate researcher at the Institute for Arctic and Alpine Research at CU Boulder.

"Of all the regions we studied, streamflow from Colorado's Rocky Mountains is most sensitive to a change in snowmelt," Barnhart said. "This analysis suggests that all of the regions studied will experience a decrease in streamflow with a decrease in snowmelt rate, with some regions exhibiting more streamflow sensitivity than others."

"The Sierra is affected similarly and, besides the Truckee River basin, Northern California will feel an impact from the reduced and early streamflows," Harpold said. "The snowpack in the Sierra is one massive reservoir that our communities, forests and river environments have come to rely on.

"Given that 60 million people in the western U.S. depend on snowmelt for their water supply, the future decline in snowmelt-derived streamflow may place additional stress on over-allocated water supplies," said Noah Molotch the director of the Center for Water Earth Science &amp; Technology CWEST in the CU Boulder Department of Geography and also a co-author of the paper.
###
Additional co-authors of the study "Snowmelt rate dictates streamflow" are, from CU Boulder, Ben Livneh, John Knowles and Dominik Schneider. The study was funded through the National Science Foundation with additional assistance from the U.S. Department of Agriculture and a <a href="https://en.wikipedia.org/wiki/NASA">NASA</a> Earth and Space Science Fellowship.

Harpold's interests are in understanding the fate and transport of water, energy, and biogeochemical solutes at the landscape scale through improved understanding of ecohydrologically mediated processes. His research threads between basic and applied science. He received his doctorate from Cornell University and his masters and batchelors from Virginia Tech. He spent time as a post-doctoral researcher at the University of Colorado and the University of Arizona.

<div>Managing methane emissions from livestock manure. It is currently not possible to quantify emissions of methane from livestock manure. This is a significant problem, in particular at a time where the EU Commision requires Denmark to reduce drastically emissions of greenhouse gases from <a href="http://www.earth.com/news/urban-agriculture-food-desert/">agriculture.</a> Without methods to quantify emissions, it is also not possible to document effects of changes in management.</div>
<div>

A new research article, published this week in the journal <a href="https://en.wikipedia.org/wiki/NASA">PLOS ONE</a>, addresses this challenge and proposes a method which could be an important step towards quantifying methane emissions and degradation processes associated with manure management.Managing methane emissions from livestock manure

The specific challenge is that the mainly liquid manure (slurry) is collected in pits under animal confinements for up to a month before exported to an outside storage tank, or for treatment. During this period degradation of manure organic matter begins and may lead to emissions of both methane and carbon dioxide. However, animals in the house are also a source of both gases, and in practice emissions from livestock and their manure cannot be separated. As a result, the total emission of methane from manure in pits and outside storage tanks, and the degradation of manure organic matter, cannot be verified.

The new method proposed here is based on laboratory measurements of methane production in liquid manure samples collected on farms. A simple model is used to calculate daily emissions. This model can then be used to evaluate effects of changes in management or treatment of the manure, for example biogas treatment.

Methane is, after carbon dioxide, the most important source of greenhouse gases from agriculture, and the most important on-farm source. Here the largest single source is animal digestion, especially in ruminants such as cattle, whereas on pig farms manure is the main source. Since the residence time of methane in the atmosphere is short compared to other greenhouse gases, a reduction of methane will be particularly effective in the short term at reducing climate forcing. Moreover, methods to reduce methane emissions from manure are already available (biogas treatment, slurry acidification). For these reasons methane emissions from livestock manure is an obviouos target for greenhouse gas mitigation.

Degradation of manure organic matter leads to emissions of methane, but even larger emissions of carbon dioxide. Both methane and carbon dioxide contain carbon from manure organic matter that is degraded. This loss of organic carbon is critical for the biogas potential of manure which is directly related to the degradable organic matter left in the manure. For example, a shorter collection period would likely increase biogas production while at the same time reducing methane emissions, but currently these effects cannot be documented. The article discusses this synergy and concludes that a new method must also be able to quantify the emission of carbon dioxide, in order to estimate the loss of degradable organic matter from slurry pits. Plans to further develop the method have been described in a new research proposal in collaboration with research institutions in Germany, Netherlands, Great Britain and Sweden, and a Swedish company.

The orange-and-black automated signs lining state highways still warn that <a href="http://www.earth.com/news/southern-california-mountain-lions-extinction/">California</a> is in severe drought, but Californians this summer are getting a second chance to show whether they can save water without the state ordering them. California lifts mandatory water restrictions showing a huge change in the savings of water.
After lifting nine months of mandatory state water restrictions for families and non-farm businesses, authorities caution that they could impose state limits again as soon as this winter should the state's 39 million people return to water-wasting, drought-oblivious ways.
"We've been clear at a state level we're still in a drought, there's still a need for conservation," Max Gomberg, conservation manager for the state Water Resources Control Board. But "we don't need people to go to extraordinary measures like they did last year."
While an El Nino system brought some rain and snow to Northern California last winter, nearly two-thirds of the state remains in severe drought or worse for a fifth year. But citing the slightly improved precipitation, California by June lifted a 25-percent mandatory conservation order in effect for cities and towns statewide for most of a year.
On Tuesday, the state announced that all but 68 of the 411 larger water districts had gotten out from under the threat of localized conservation orders from the state. The water agencies did that by declaring they had enough water to get by even if the drought lasts another three years.
Environmental groups are skeptical all the water districts have as robust a water supply as they claim, and say lifting of mandatory conservation sends the wrong message to ordinary Californians as the drought persists. California lifts mandatory water restrictions
"Moving to zero percent mandatory conservation - it's a confusing message to be sending to California. We're in the midst of the hottest summer on record and fighting raging wildfires," said Tracy Quinn, senior water policy analyst at the Natural Resources Defense Council environmental group.
Water agencies, however, say they have built water-conservation into their operations now.
Most water districts had to raise rates last year, which gives consumers an incentive to save, said Tim Quinn, executive director of the Association of California Water Agencies trade group. Most water <a href="https://en.wikipedia.org/wiki/NASA">districts</a> also offered water-saving incentives, such as paying customers to remove thirsty lawns.
What the lifting of mandatory conservation means is that this summer, unlike last, Californians don't have to do things like keep a bucket in the shower to catch water for reuse, the water-industry representative said.
"It is the end of inconvenience, but it is not the end of conservation," Tim Quinn said.
Californians didn't do well the last time someone asked them to voluntarily save water. In 2014, requested by Gov. Jerry Brown to cut water use 20 percent given the drought, Californians managed less than half of that.
Brown made 25 percent conservation mandatory for cities and towns in spring 2015.
This time around, state officials will be happy if Californians manage around 20 percent water savings, compared to the benchmark water-use year of 2013, said Gomberg, the state water official. If people manage just 10 percent conservation or less now, that would be cause for concern for state water officials when they revisit the matter after January, Gomberg said.
In Palm Springs, water-agency spokeswoman Ashley Metzger said Wednesday that local water officials were still pushing hard on conservation programs, including kicking off a new rebate program promoting lawn removing at noon that day.
"Oh, my goodness, yes," Metzger said, when asked if she expected strong demand for the lawn-removal rebates.
Metzger's district, the Desert Water Agency, is now asking customers to keep water use down by 10- to 13 percent, voluntarily, she said.
The Palm Springs message to water users in summer 2016? "We have a strong local supply but there's a still a statewide issue" with water, Metzger said. "I think it's definitely a nuanced message."

<div class="img-wrapper">Study: Meadow full of flowers benefit mankind The more it swarms, crawls and flies the better it is for humans. This is the finding of a study published in "Nature". More than 60 researchers from a number of universities were involved, including the Technical University of <a href="http://www.earth.com/news/space-agencies-asteroid-defense/">Munich</a>, the Institute of Plant Sciences at the University of Bern and the Senckenberg Biodiversity and Climate Research Centre in Frankfurt. A diverse ecosystem populated by many species from all levels of the food chain provides higher levels of ecosystem services, the team reports. Even rather unpopular insects and invisible soil-dwelling organisms are important in maintaining a wide range of <a href="https://en.wikipedia.org/wiki/NASA">ecosystem</a> services. The results underline the necessity of maintaining species-rich ecosystems for the good of humanity.</div>
Grasslands full of flowers are not only beautiful they also provide many important services for humans. These include food production, alongside supporting services such as soil development, regulating services such as pest control and climate regulation and cultural services such as the use of the grassland for recreation. A grassland is also a complex ecosystem containing many species belonging to different levels in the food chain, so called "trophic levels".Study: Meadow full of flowers benefit mankind

Humans are causing declines in biodiversity for many of these groups and evidence from experiments on plants suggests this might threaten ecosystem services. However, studies had not looked at diversity at many trophic levels at the same time.

A 60-strong research team, led by Dr. Santiago Soliveres from the University of Bern, therefore studied all groups in a grassland food chain for the first time. They collected data on a total of 4600 species of animal and plant from nine trophic groups, including often neglected ones such as micro-organisms in the soil and insects that live in the soil or on the plants. "The data was collected as part of a programme supported by the Deutsche Forschungsgemeinschaft in 150 grasslands across Germany, the so called 'Biodiversity Exploratories'", says Professor Wolfgang Weisser of the Chair for Terrestrial Ecology at the Technical University of Munich (TUM) - "it constitutes the most extensive ecological sampling in Europe."

[caption id="attachment_2410693" align="alignleft" width="150"]<img class="size-thumbnail wp-image-2410693" src="http://cff1.greenatom.earth/uploads/2016/08/17135013/cff1.greenatom.earthuploads20160817135012media.eurekalert.orgmultimedia_prodpubweb122073_web-068b81c384ef161d31636e90882885eb763237d4-60cd34d80bee67f439da6cbaae34562fadad43d9-150x150.jpg" alt="Meadow clary (Salvia pratense)" width="150" height="150" /> Meadow clary (Salvia pratense)[/caption]

Biodiversity required within all trophic groups

"Working out how different groups affect ecosystem services is like trying to solve a very complicated puzzle but with our extensive data we are able to put together a coherent picture of how important individual groups are for fourteen ecosystem services. Each ecosystem service is dependent on at least three groups and the higher the number of species within the group, the more reliably the ecosystem service is provided. In addition, each individual group influences at least one ecosystem service," Soliveres, lead author for the study, summarises the results.

Dr. Eric Allan from the University of Bern adds: "Many different groups are important for providing essential ecosystem services. In order for nature to continue 'working' reliably for us we therefore need to protect biodiversity at all levels in the food chain, including in often overlooked groups such as microbes or insects. This is especially important for regulating processes and cultural services."

The importance of overlooked organisms

Microbes and insects are overlooked and are not generally considered in conservation. However, this study shows that view needs to change because many insects and soil organisms play a central role, alongside plants, in supplying the services we depend on. "Plants supply biomass which forms the beginning of the food chain, but insects act as pollinators and soil organisms increase soil fertility through the breakdown and retention of chemical elements such as phosphorus. The more different species there are, particularly within these three groups, the more positive the effect on all services," explains Soliveres.

Often, fertiliser is applied to the soil in order to increase soil fertility and thus increase plant growth. Fertilisers help in the short term, but if biodiversity is reduced, then the downsides outweigh this. Maintaining high levels of biodiversity throughout the food chain is therefore more economical and wiser in the long term than destroying it for short term gains.

The importance of biological diversity for ecosystem services has been underestimated

"If biodiversity is rapidly destroyed, what consequences does this have for humans? What courses of action are available? Thus far, there has been insufficient research into this, which is one of the reasons why the international biodiversity council IPBES was founded," explains Prof. Markus Fischer from the Institute of Plant Science at the University of Bern and head of the Biodiversity Exploratories project. This study also shows that the importance of biological diversity has been underestimated because previous research only focussed on individual trophic groups: "Our extensive research programme demonstrates how important it is to study the broader context and that there is a need for action to protect ecosystems," summarises Fischer.

Debate rages over Papahanaumokuakea Marine National Monument.As a Native Hawaiian living in modern Hawaii, one of the times Shad Kane truly felt connected to his ancestors was when he traveled to a remote, 140,000-square-mile area of the Pacific where islands, atolls, islets and coral reefs make up a federally protected marine monument.
There, at Midway Atoll, he plucked feathers from dead birds to make kahili - feathers mounted on a long wooden pole that was used to announce the presence of ancient Hawaiian chiefs and became a royal symbol during the Hawaiian monarchy.Debate rages over Papahanaumokuakea Marine National Monument
"Going to Midway and being a part of gathering traditional birds in the manner they did is extremely spiritual," the suburban Honolulu man said this month. "It becomes much more personal for me."
He said seeing Midway strewn with remnants of fishing nets, buoys and hooks helped him realize the surrounding area needs protection, too.
This year, a group of Native Hawaiian leaders urged President Barack Obama to expand Papahanaumokuakea Marine National Monument, while keeping the main Hawaiian islands outside the boundaries. The move would make the monument about 582,000 square miles, more than twice the size of Texas.
The White House isn't indicating when a decision will be made. Obama also has been asked to designate new national monuments in Utah, <a href="https://en.wikipedia.org/wiki/Arizona">Arizona</a>, <a href="http://www.earth.com/news/sierra-nevada-mountains-taller/">Nevada</a>, Maine and elsewhere.
The effort to expand the Pacific monument has supporters and opponents invoking Hawaiian culture to further their agendas. Some believe expansion of one of the world's largest marine conservation areas will protect a sacred place, while others say making more waters off-limits will harm fishermen for a cause pushed by environmentalists with deep pockets.
A presidential proclamation established the monument in 2006. Only scientific research and cultural activities are allowed, with commercial fishing and recreational activities such as diving banned.
Getting there requires taking a flight to Midway Atoll or a sailboat. Under ideal ocean conditions, it takes about two days to sail from Kauai to Nihoa, the closest island to the main Hawaiian islands.
Some who say the area needs to be open for commercial fishing rely on an argument that's "completely contrary to the generation that preceded them that actually did go fish and understood the harmful effects" of overharvesting, said William Aila, deputy director of the Department of Hawaiian Home Lands.
Peter Apo opposes adding the massive area to the monument and said doing so contradicts the way ancient Hawaiians managed natural resources.
Apo is a trustee of the Office of Hawaiian Affairs, which supports expansion as long as the agency gets an official say in management of the area, including advocating for Native Hawaiian access.
It's difficult to be a Native Hawaiian and an expansion opponent, Apo said.
"We look like we're bad guys. We're opposing what seems to be addressing a global problem," he said of issues like climate change and overfishing that supporters point to.
He cited how Hawaiians utilized periods of kapu, or temporary restrictions in response to overharvesting.
"Food security was critical to Hawaiians," Apo said.
It's difficult to estimate the financial effect that expansion would have on the $100 million per year longline industry, which supplies a large portion of the fresh tuna and other fish consumed in Hawaii, said Sean Martin, president of the Hawaii Longline Association.
He estimated about 2 million pounds of fish annually come from the proposed expansion area, where vessels string lines ranging from a mile to 50 miles long in the ocean to catch fish.
G. Umi Kai, who uses his spare time to craft traditional implements such as wooden weapons and fish hooks made of bone, experienced the tranquility, isolation and fragility of the area when he visited last year.
He fished off rocky shores of two islands in the monument to see if his traditional bone hooks really worked. It was an ideal place for the test, he said, "because the environment was closer to the way Hawaii was 100 years ago."
Aila, of the home lands department, said he hopes the issue will draw Obama to an international environmental conservation gathering scheduled for next month in Honolulu.
By expanding the monument, Aila said the president could build a legacy as well as commit the U.S. to fighting environmental problems such as climate change and coral bleaching, which occurs when warm waters lead coral to expel the algae they rely on for food.
Opponents hope the president sees how divisive the issue is.
"I'm not sure that Obama, who was born, raised here, wants to leave a legacy of a divided Hawaii," Apo said.

<div class="img-wrapper">The Blue Cut Fire in California is growing quickly. The Blue Cut Fire, just outside of Los Angeles, is a quickly growing fire that is currently an imminent threat to public safety, rail traffic and structures in the Cajon Pass, Lytle Creek, Wrightwood, Oak Hills, and surrounding areas. An estimated 34,500 homes and 82,640 people are being affected by the evacuation warnings that have been issued. This wildfire started on August 16, 2016 and the cause is unknown. In the last two days the fire has grown to 31,689 acres with 1584 personnel on scene. 178 engines, 26 crews, 10 air tankers, 2 Very Large Air Tankers (<a href="https://en.wikipedia.org/wiki/NASA">VLATS</a>), and 17 Helicopters, including night flying helicopters. Additional firefighters and equipment have been ordered and will be responding directly to the fire. An unknown number of structures are damaged and destroyed. A smoke advisory has been issued for portions of <a href="http://www.earth.com/image/fire-and-smoke-in-san-bernardino-national-forest/">San Bernardino</a> Country.</div>
Unfortunately extreme weather is continuing in the area with hot, dry and breezy (20 mph with gusts to 30 mph) conditions. Very poor relative humidity will continue. All of these will hinder fire fighting efforts and may increase fire spread. The Blue Cut Fire in California is growing quickly

On Aug. 17 at 11:24 a.m. EDT (15:24 UTC) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard <a href="https://www.bing.com/search?q=nasa&amp;cvid=55bb30931e0e4101bf22896a732ab562&amp;FORM=ANAB01&amp;PC=HCTS">NASA</a>-NOAA's Suomi NPP satellite captured a visible light image of Tropical Depression 6 as it was strengthening into Tropical Storm Fiona. At the time, the National Hurricane Center noted that the depression's overall cloud pattern and low-level wind field continued to improve, as was visible in the Suomi NPP image.

The depression became a tropical storm at 5 p.m. EDT and the sixth named storm of the <a href="http://www.earth.com/image/the-2020-atlantic-hurricane-season-was-supercharged/">Atlantic</a> Ocean Hurricane Season.

Southwesterly wind shear that had pushed the bulk of clouds and showers to the northeast of the storm's center on August 8 had weakened and has kicked up again on Aug. 11 and Aug. 12. The southwesterly winds were as strong as 23 mph (20 knots/37 kph).

At 11 a.m. EDT (1500 UTC), the center of Tropical Storm Fiona was located near 16.4 north latitude and 40.5 west longitude, about 1,095 miles (1,760 km) west of the Cape Verde Islands. Fiona is moving toward the west-northwest near 8 mph (13 kph) and the National Hurricane Center said this general motion is expected to continue during the next couple of days. The estimated minimum central pressure is 1006 millibars. Tropical Storm Fiona forms in the northeastern Atlantic Ocean

Maximum sustained winds are near 45 mph (75 kph) with higher gusts. Slow strengthening is possible during the next day or so, followed by gradual weakening over the weekend.

Melting glaciers pose flood risk The tropical glaciers of <a href="http://www.earth.com/image/deforestation-south-america/">South America</a> are dying from soot and rising temperatures, threatening water supplies to communities that have depended on them for centuries. But experts say that the slow process measured in inches of glacial retreat per year also can lead to a sudden, dramatic tragedy.
The melting glaciers like Peru's Pastoruri has put cities like Huaraz, located downslope from the glacier about 35 miles (55 kilometers) away, at risk from what scientists call a "glof" - glacial lake outburst flood.
A glof occurs when the weak walls of a mountain valley collapse under the weight of meltwater from a glacier. Recent examples include the rapid draining in 2013 of a lake at <a href="https://www.bing.com/search?q=chile&amp;form=EDGEAR&amp;qs=PF&amp;cvid=2e8824ba01414e68bcd96673651181e5&amp;cc=US&amp;setlang=en-US&amp;elv=AXK1c4IvZoNqPoPnS%21QRLOPIoNehwT*BZsBaH8EUV3qrP38tbAH3UeUhIiEu8jCeA7S7dKUP4WKai*jYaBLlsMfkv2fGLj9RH8k5Zg7YUL%21%21&amp;plvar=0&amp;PC=HCTS">Chile's</a> Ventisquero glacier in the Bernardo O'Higgins National Park, six years after another, nearby lake essentially disappeared there.Melting glaciers pose flood risk
Those sites are in remote, sparsely populated Patagonia. But if the glacial Palcacocha lake collapsed, it could cause a damaging flood, say experts in Peru, sort of like a smaller, modern cousin of the ancient glof that is thought to have carved the English Channel.
"As glaciers disappear around the world, there is less water available for use for hydroelectric power, as a renewable resource for agriculture, for human consumption," said Benjamin Orlove, a professor of international and public affairs at Colombia University in New York. "The glacier retreat also brings many disasters. Entire slopes are destabilized, creating landslides that travel many miles and have destroyed entire towns."
Benjamin Morales Arnao, the head of Peru's National Institute for Glacier Research, said that while the country's glaciers "are a source of life, due to their water resources and biodiversity ... these glaciers are also a source of glacial catastrophes."
The problem is that glacial lakes are often fragile structures, created when rocks and rubble carried by a glacier form a moraine that dams up its water outflow. The dam can also be created by chunks of a glacier's own ice. These inherently unstable structures can collapse quickly, especially in a place like Peru that is prone to frequent, violent earthquakes.
At a conference last week on the glacier retreat in Peru, Morales Arnao said that Huaraz, a city of about 100,000 people, is particularly at risk from Palcacocha lake, just 12 miles (20 kilometers) up the mountain above the city, and called for resources to mitigate the risk. Dams, spillways and other waterworks have helped in other places.
Massive glofs have occurred regularly in sparsely populated parts of Iceland and other nations.
The International Centre for Integrated Mountain Development, a regional intergovernmental research center that serves the eight countries of the Himalayas, said that in Nepal - whose proximity to the highest and largest meltwater sources in the world makes it particularly vulnerable - "little attention was paid to the phenomenon until the sudden outburst of the Dig Tsho," a relatively small meltwater lake in the Mount Everest National Park.
On Aug. 4, 1985, the lake's moraine dam collapsed, and all its water drained into a downstream valley in four hours, causing losses as far as 30 to 35 miles (50 to 60 kilometers) downstream.
A large ice and rock avalanche had cascaded into the lake, creating a wave that spilled over the moraine and caused it to collapse, the center's report said. "It discharged an estimated 6 to 10 million cubic meters (as much as 2.6 billion gallons) of water into the valley below."
Digging stone- or cement-lined channels through glacial dams is one solution to the threat. Many moraine dams collapse because meltwater erodes them by seepage or over-topping them. Stopping global warming that is increasingly causing glaciers to melt is another.
Experts at the International Forum on Glaciers and Mountain Ecosystems held in Huaraz last week concluded that the world is going to have to plan on melting glaciers, at least for the time being.
"The processes of climate change and glacial melting are irreversible," the forum said in its conclusions. "We have to carry out actions to adapt, and mitigate the risks."
"The long-term solution is for the world to shift to different energy sources, sources that are renewable, sources that do not emit gases that cause climate change," Orlove said. "In the short term we have to find adaptations, like installing early warning systems for disasters in the most sensitive areas."

The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite provided an infrared look at Tropical Depression 10W on Aug. 18. 10W has some strong thunderstorms around the center of circulation that appeared to have cold top temperatures as cold as minus 80 degrees Fahrenheit (minus 62.2 degrees Celsius). Cloud tops that cold are high into the troposphere (lowest layer of the atmosphere) and have the potential to generate heavy rainfall.

At 11 a.m. EDT (1500 UTC) on August 18, 2016 Tropical Depression 10W was centered near 16.5 degrees north latitude and 143.4 degrees east longitude, about 189 nautical miles north-northeast of Andersen Air Force Base, <a href="http://www.earth.com/endangered-species/bulbophyllum-guamense/">Guam</a>. 10W has tracked north-northwestward at 10.3 mph (9 knots/16.6 kph) and is expected to continue moving in that direction. Maximum sustained winds were near 34.5 mph (30 knots/55.5 kph). Also Tropical Depression 10W forms near Guam caused a lot of damage.

The Joint Typhoon Warning Center forecast calls for Tropical Storm 10W to move in a generally northerly direction over the next several days while intensifying slightly to a minimal tropical storm. The forecast takes 10W to the central part of the big island of Japan by Aug. 22 and 23.

<div class="img-wrapper">Aqua satellite passed over tropical cyclone Kay. NASA's Aqua satellite passed over tropical cyclone Kay as it was designated a depression in the Eastern Pacific and identified areas of strong convection. That strong uplift of air continued to generate more powerful storms in the system and on Aug. 19 it strengthened into a tropical storm.</div>
The Atmospheric Infrared Sounder or AIRS instrument that flies aboard <a href="https://www.bing.com/search?q=nasa&amp;cvid=299dd5dbf21847d480e60daa950d8a7d&amp;FORM=ANAB01&amp;PC=HCTS">NASA's</a> Aqua satellite analyzed Kay as it was classified as a depression on Aug. 18 at 4:53 p.m. EDT (2053 UTC).

AIRS looked at Tropical Depression Kay in infrared light, gathering temperature data of the system's clouds. Coldest cloud top temperatures appeared south of the center at that time where some temperatures of the strongest storms exceeded minus 63 degrees Fahrenheit (minus 53 degrees Celsius). Storms with temperatures that cold are high in the troposphere and NASA research has shown they have the ability to generate heavy rain. Aqua satellite passed over tropical cyclone Kay

By 5 a.m. EDT on Friday, Aug. 19, Kay had strengthened into a tropical storm and became the eleventh named tropical cyclone of the eastern Pacific Ocean hurricane season.

At that time the National <a href="https://www.bing.com/search?q=hurricane&amp;cvid=c4e16a08dc774b54a1d6621b517e0119&amp;FORM=ANAB01&amp;PC=HCTS">Hurricane</a> Center (NHC) said the center of Tropical Storm Kay was located near 18.4 degrees north latitude and 110.9 degrees west longitude. That puts the center of Kay about 315 miles (510 km) south-southwest of the southern tip of Baja<a href="http://www.earth.com/image/tule-fog-across-californias-central-valley/"> California,</a> Mexico, and just 30 miles (45 km) south-southeast of Socorro Island.

NHC said Kay was moving toward the northwest near 7 mph (11 kph) and is expected to turn toward the north-northwest with a decrease in forward speed. Maximum sustained winds have increased to near 40 mph (65 kph) and no significant change in strength is forecast during the next day or so.

Kay is forecast to move to the northwest and once it is parallel to the southern tip of Baja California, it is forecast to weaken to a depression and turn away from land and head west into the Eastern Pacific.

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."

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;

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.
