Once upon a time, <a href="https://www.earth.com/news/personality-type-can-accurately-predict-your-relationship-status/" target="_blank" rel="noreferrer noopener">standing out</a> and embracing uniqueness was desirable. However, recent studies suggest a major change over the past two decades. It seems we've become fond of the idea of blending in, of being just another face in the crowd.



Enter William Chopik, associate professor in the Department of Psychology at <a href="https://msu.edu" target="_blank" rel="noreferrer noopener">Michigan State University</a>. Chopik is the lead author of a study that uncovers a dramatic decline in the desire to be different. That's right, we're less keen on standing out these days, and it's all backed by some pretty formidable evidence.



<h2 class="wp-block-heading" id="h-quest-for-uniqueness">Quest for uniqueness</h2>



The study spans a period of 20 years, from 2000 to 2020. Its findings track the desire for individualism in a whopping million people.



Uniqueness, for the purpose of this study, is broken down into three facets: worry over others' perceptions, the urge to break the established norms, and the readiness to publicly uphold personal beliefs. But, all three of these elements saw a decline during the study period.



<h2 class="wp-block-heading" id="h-why-are-we-afraid-to-stand-out">Why are we afraid to stand out?</h2>



The most staggering drops were seen in the public defense of <a href="https://www.earth.com/news/personality-is-more-important-than-finances-when-it-comes-to-dating/" target="_blank" rel="noreferrer noopener">personal beliefs</a> (6.52% decline), and an increasing concern about public opinion (4.28% decline). These numbers might sound small, but as Chopik points out, "a 6.52% decline is a dramatic population change in as short as 20 years."



And why these drops? The data points to a possible explanation. Perhaps individuals see expressing their uniqueness as a threat to social acceptance. Yes, standing out might make them vulnerable to exclusion. Or worse, cancellation.



<h2 class="wp-block-heading" id="h-is-it-truly-worthwhile">Is it truly worthwhile?</h2>



Chopik's study warns us of the possible implications of this trend. Suppressing our true selves to fit into societal molds can sometimes have an adverse effect, triggering feelings of guilt and anxiety. And let's not forget, this often leads to increased hostility.



"It's really important to have people willing to go against the grain - say the occasional unpopular thing, challenge groupthink, highlight the need to compromise with people different than us, and not cover up the diversity of opinions and people because they're too scared to stand out," says Chopik.



<h2 class="wp-block-heading" id="h-perceptions-of-uniqueness-on-social-media">Perceptions of uniqueness on social media </h2>



In today's interconnected world, social media platforms wield immense power over individual perceptions and behaviors. While these platforms can facilitate the expression of diverse opinions and lifestyles, they also contribute to a culture of comparison and conformity. 



As users curate their online personas, the pressure to fit in intensifies, often leading to a hedonic treadmill of dissatisfaction where uniqueness is celebrated only if it conforms to prevailing trends. 



Chopik’s study provides critical context here: as the desire for uniqueness declines, it begs the question: are we shaping our identities based on genuine self-expression or merely mirroring the expectations set by our digital environments?



<h2 class="wp-block-heading" id="h-reclaiming-individuality">Reclaiming individuality</h2>



Despite the unsettling trend of conformity, there lies an opportunity for revitalizing the celebration of uniqueness. To counteract societal pressures, individuals can begin cultivating a mindset that embraces <a href="https://www.earth.com/news/personality-traits-are-not-strongly-inherited-from-parents/" target="_blank" rel="noreferrer noopener">self-acceptance</a> and authenticity.



Engaging in open dialogues about differences, fostering environments that encourage dissenting opinions, and understanding the value of diverse perspectives are vital steps. 



We must not cover up the diversity of opinions, but rather embrace them. Ultimately, reclaiming our individuality not only enriches our lives but also contributes to a more nuanced and empathetic society.



<h2 class="wp-block-heading" id="h-an-appeal-for-authenticity">An appeal for authenticity</h2>



In an age where everyone seems connected through various platforms, we find ourselves paradoxically isolated in our personal lives. This raises an important question: is it truly worth sacrificing our individuality to fit into a crowd? 



While the notion of standing out may feel intimidating, especially in a world that often celebrates conformity, we should consider the value of being authentic. Embracing our true selves allows us to form deeper connections with others and to live more fulfilling lives. 



It's essential to recognize that the cost of blending in can be higher than the fear of being different. After all, authenticity fosters genuine relationships and enriches our experiences. The pursuit of fitting in may not be worth the price we pay.



Embracing our uniqueness can be a powerful way to inspire others and create a more diverse and vibrant community. Isn't it time we embraced our individuality, in all its vibrant <a href="https://www.earth.com/news/cryptocurrency-investors-linked-to-dark-personality-traits/" target="_blank" rel="noreferrer noopener">diversity</a>?



The study is published in the journal <a href="https://online.ucpress.edu/collabra/article/10/1/121937/202992/Changes-in-Need-for-Uniqueness-From-2000-Until" target="_blank" rel="noreferrer noopener">Collabra: Psychology.</a>

Humans are losing 'uniqueness' as people no longer desire to stand out

Once upon a time, standing out and embracing uniqueness was desirable. However, recent studies suggest a major change over the past two decades. It seems we've become fond of the idea of blending in, of being just another face in the crowd. Enter William Chopik, associate professor in the Department of Psychology at Michigan State University. Chopik is the lead author of a study that uncovers a dramatic decline in the desire to be different. That's right, we're less keen on standing out these days, and it's...

After the <a href="https://www.usa.gov/federal-agencies/u-s-department-of-agriculture">U.S. Department of Agriculture</a> pulled public animal welfare data from its website, the <a href="http://www.humanesociety.org">Humane Society of the United States</a> is threatening a lawsuit.

The government website had previously featured access to a public database of animal welfare records from circuses, zoos, research <a href="http://www.earth.com/news/lab-chip-costs-penny/">labs</a>, dog breeders, and other animal-related operations throughout the country. Potential dog adopters were able to access the website to check out individual dog breeders to ensure that they were purchasing from a facility that was free of violations. 

Now, all of that information has disappeared, available only via a request through the Freedom of Information Act. 

The Humane Society is fighting back. “We intend to sue them unless they take remedial action here,” Wayne Pacelle, the President and CEO of the Humane Society said in interview with<a href="http://www.apple.com"> TIME</a>. 

Animal rights advocates are concerned that without the public keeping an eye on violations, many breeders and animal handlers won’t be as concerned with compliance with animal welfare laws. The reason behind the removal of the information is concerning to animal rights organizations. 

“It’s going to impact every species of animals,” explained Elizabeth Oreck. She handles puppy mill initiatives for<a href="http://bestfriends.org"> Best Friends Animal Society</a>. “There shouldn’t be any reason to hide inspection reports for a dog breeding facility or a research lab. There shouldn’t be any need to keep from the public how many animals you have [in] your facility or whether or not you’re complying with care standards. That alone is a big red flag for everybody,” she said. 

The USDA cited “privacy rights” in a statement about the disappearance of the information. “APHIS is implementing actions to remove documents it posts on APHIS’ website involving the Horse Protection Act and the Animal Welfare Act that contain personal information,” it said. 

“Going forward, APHIS will remove from its website inspection reports, regulatory correspondence, research facility annual reports, and enforcement records that have not received final adjudication.”

Oreck says that the removal of the information has inspired advocates to fight even harder for animal welfare and safety.

A leading association of hemp advocates is suing the<a href="https://www.dea.gov/index.shtml"> Drug Enforcement Administration</a> (DEA) over claims that the agency violated a court order when it started cracking down on products made with hemp in letters sent out last December.

For decades, cannabis has been illegal under U.S. federal law. However, regulation of cannabis has also lead to a crackdown on hemp, its non-psychoactive cousin. While the form of cannabis we traditionally know as marijuana has high (no pun intended) amounts of THC, industrial hemp has amounts of less than 0.3%. In other words, you could smoke a truckload of hemp and not get high.

Despite this, products like hemp seed and hemp seed oil remained illegal for years in the U.S. In 2004, the<a href="https://www.thehia.org"> Hemp Industries Association</a> (HIA) sued the DEA in a case that became known as the “Food Rules Challenge.” The Ninth Circuit Court of Appeals sided with the HIA, ruling that hemp does not belong on the list of Schedule I controlled substances. In 2014, Congress passed a Farm Bill that gave permission for states to grow hemp under a special licensing program. 

Late last year, the DEA struck again, this time working with the<a href="https://www.nd.gov/ndda/"> North Dakota Department of Agriculture</a> (NDDA) to send correspondence to<a href="https://www.healthyoilseeds.com"> Healthy Oilseeds, LLC</a>. The company was informed that in order to ship their hemp protein powder and hemp seed oil products, they’d have to get a permit from the DEA.  

The HIA is fighting back, claiming that the DEA has overstepped its bounds, violating the intent of the Farm Bill, as well as the Consolidated Appropriations Act of 2016, which prevents authorities from using funds to stop the “transportation, processing, sale, or use of industrial hemp.” They have filed a Petition for Review with the Ninth Circuit Court of Appeals.

“It is disappointing that the industry has to revisit the issue, and take this step to compel DEA to obey the law,” said Joe Sandler, HIA’s lead counsel.

Bogus global warming data at the center of new debate. A whistleblower from the<a href="http://www.noaa.gov"> National Oceanic and Atmospheric Administration</a> (NOAA) has released evidence claiming that the organization used manipulated data to influence world leaders ahead of the 2015 UN climate conference in Paris.

The paper released by NOAA denied any supposed “pause” in global warming since 1998 and instead reported that world temperatures had been rising at an unanticipated rate. 

It likely influenced top policymakers such as President Barack Obama and UK Prime Minister David Cameron when they met in Paris for the conference that year. There, world leaders came together to work on an agreement for their nations to cut back on the use of fossil fuel in an effort to prevent further warming. 

Both sets of data used to compile the report were flawed. One set focused on temperature measurements from the Earth’s surface, while the other measured the temperature at the surface of the seas. The latter set is so flawed that NOAA is calling for it to be replaced because it used unreliable methods that overstate temperatures levels and how quickly they are rising.

This information came to light when John Bates, a top scientist at NOAA, gave an exclusive interview to the<a href="http://www.dailymail.co.uk/ushome/index.html"> Daily Mail</a>. He objected to the publication of the Pausebuster paper, a report that he said was never subjected to NOAA’s typically-rigorous internal evaluation process. 

Bates accused Thomas Karl, the lead author of the paper, of “insisting on decisions and scientific choices that maximized warming and minimized documentation… in an effort to discredit the notion of a global warming pause.” Bates said Karl “rushed so that he could time publication to influence national and international deliberations on climate policy.”

For his part, Karl denies that the intention of publishing the Pausebuster data without putting it through further review was to influence lawmakers about to convene for the climate conference. “There was no discussion about Paris,” he said.

This scandal is sure to add fuel to the fire of the heated debate over the science behind climate change.

World leaders swayed by bogus global warming data

Recycle, recycle, recycle. We hear it all the time, but rarely note the repercussions of simply tossing items in the trash. Unfortunately, throwing away items like <a href="http://www.earth.com/news/beach-plastic-shampoo-bottles/">plastic</a> bags can have unintended consequences. Such was the case off the coast of Norway, where zoologists report finding a dying whale with a stomach full of plastic bags and other plastic waste. They believe that the contents of its digestive system were “probably the reason” the 2-ton goose-beaked whale fell ill. 

Plastic bags are an ecological nightmare – particularly for marine life. Sandwich bags and plastic food film are problematic, but marine biologists are alarmed over the danger that plastic shopping bags pose to a wide variety of sea creatures like the poor dying whale.

These thin, disposable bags are everywhere. Stores first started using them in the 1970s and today, more than 1 billion of them are used every day. According to the <a href="http://www.latimes.com/">Los Angeles Times</a>, they’re the most common piece of trash found littering California’s beaches.

Why is this a problem for marine creatures? A free-floating plastic bag is easily mistaken for food. In particular, the bags resemble jellyfish to hungry sea turtles. It’s an issue for more than just sea turtles, however – seabirds and whales such as the unfortunate one found in Norway are also affected. 

As plastic fills up the stomachs of sea turtles and other creatures, it leaves no room for food, causing the animal to slowly starve to death.

Terje Lislevand of the <a href="http://www.uib.no/en/node/36362">University of Bergen</a> told the <a href="https://www.ap.org/en-us/">Associated Press</a> that the whale "had no food, only some remnants of a squid's head in addition to a thin fat layer” in its intestine. The whale was suffering, beyond medical help, and had to be euthanized. 

In a report from the World Economic Forum, scientists warned that by 2050 there will be more plastic floating in our oceans than there is sea life.

Officials insist that it’s necessary to prevent wild bison from spreading disease. Wildlife advocates decry it as misguided and unnecessary. As the two sides face off, a plan to slaughter hundreds of wild bison in <a href="http://www.earth.com/news/obama-moves-block-new-mining-near-yellowstone-national-park/">Yellowstone National Park </a>is moving forward. 

After two weeks of negotiations between the state of Montana, Yellowstone, and the U.S. Department of Agriculture, all parties agreed to allow the plan, which will involve the slaughter of up to 1,300 of the 5,500 Yellowstone bison. The agreement spares 25 bison earmarked for the Fort Peck Indian Reservation, where conservationists are working to establish new herds. 

Proponents of the slaughter say that it’s a necessary part of a 16-year program developed to prevent bison from spreading brucellosis to cattle. Brucellosis, a disease that causes abortion in pregnant animals, only currently exists in among the wildlife in the Yellowstone area. It’s been eradicated throughout the rest of the nation. 

The bull bison selected for the repopulation program at Fort Peck will be quarantined and watched for disease for a year. Jody Lyle, a spokeswoman for Yellowstone, says that this is an important step in a program designed to choose disease-free bison for conservation efforts. 

Critics of the slaughter disagree. "Stop the slaughter, let them roam and manage them just like we do with elk, just like we do with deer, just like we do with other wildlife,” Stephany Seay of the Buffalo Field Campaign told the<a href="https://www.ap.org/en-us/"> Associated Press</a>. She suggests giving the Montana wildlife agency jurisdiction over wild bison. Currently, that power rests with the state’s livestock department. 

According to research, there have been no recorded instances of wild bison transmitting brucellosis to livestock. This is partly due to hunters shooting bison as the animals leave the park in search of food at lower elevations. More than 300 bison were killed this winter, and over 5,000 have been killed or captured since 1985.

When a <a href="http://www.earth.com/news/new-nuclear-reactor-design/">nuclear</a> catastrophe happens, scientists rely on robotic probes to give them an insider’s view of conditions at the site. Such is the case at Japan’s Fukushima nuclear plant. However, radiation levels are currently so high at the plant that even robotic welfare is being put in jeopardy. Why? They’ll melt. 

On March 11, 2001, a tsunami developed after an undersea earthquake shook the area off the coast of Fukushima. The giant wave killed more than 18,000 people and wiped out the nuclear plant there, sending three reactors into meltdown.

Since then, the Japanese government has worked hard to clear up the site, a process that it expects to cost as much as $190 billion and span decades. Part of the reason the cleanup is moving so slowly is the high radiation levels around the site.

Until recently, scientists at the Tokyo Electric Power Co (TEPCO) used radiation-resistant robot probes with attached cameras to wander through reactors and monitor conditions. The robots are about two feet long and small enough to move through a 4-inch-wide pipe that leads into the reactor’s containment vessel.

Radiation levels are measured in seiverts per hour. Robot probes are made to withstand exposure levels up to 530 sieverts per hour – and levels inside one of the reactors have just hit that critical threshold. Robots sent in to operate at that exposure level will shut down within a mere two hours. 

Thankfully, TEPCO reports that the radiation is confined within the reactor and there are no leaks. They say that the high radiation levels are likely confined to a single point. This means that if a robot is moving around, it can likely continue to operate within the reactor – providing real hope for a continued monitoring and recovery process.

The Women’s March on January 21 attracted hundreds of thousands of women around the world who, alarmed at the misogynistic language of the Trump campaign that preceded his election and inauguration, gathered to make their voices heard. Inspired by the power behind that event, supporters of <a href="http://www.earth.com/news/science-advisor-trump/">science</a> are planning a similar one – a <a href="https://www.marchforscience.com">March for Science</a> in Washington D.C..

Planned for <a href="http://www.earthday.org/">Earth Day</a> on April 22, the March for Science will take Washington by storm. Only a week after it was announced, the movement’s Facebook and Twitter accounts have attracted over 1.3 supporters. 

Jonathan Berman, a postdoctoral fellow at the<a href="http://www.utexas.edu"> University of Texas</a>, worked to organize the march. He told the<a href="https://www.nytimes.com"> New York Times</a> that the march isn’t about political protest, but about holding decision makers in Washington accountable for listening to evidence. 

Berman said that when he first thought about the potential impact of a Scientists’ March on Washington, he “thought someone should do that – and I realized, I’m someone.” 

His idea quickly gained steam, garnering over 700,000 followers on social media within the first three days of its launch. Science writer and public health researcher Caroline Weinburg joined up with Berman. She says the response from supporters and volunteers has been “overwhelming” and “heartwarming.” 

This isn’t the first time scientists have gathered to speak out. A group of<a href="http://www.earth.com/news/womens-march-speak-trump/"> female scientists in lab coats</a> made waves and garnered huge support at the Women’s March.  

Although critics of the March for Science worry that it could garner negative attention and result in scientists losing their public support, organizers of the march remain undeterred. At the moment, their main problem isn’t support – it’s figuring out the logistics behind having thousands of people descend upon on the National Mall.

<a href="http://www.earth.com/news/epa-volkswagen-intentionally-violates-clean-air-act/">Volkswagen</a> owners were left fuming a few years ago when they discovered that the car manufacturer had fitted emissions-cheating software to many of its diesel vehicles. They sued Volkswagen and auto supplier <a href="http://www.bosch.us/content/language1/html/2274.htm">Robert Bosch</a>, and now the defendants have reached a Dieselgate settlement and have agreed to pay out $1.22 billion and $327.5 million, respectively. 

The PR nightmare for Volkswagen began when it was discovered that for ten years, they had knowingly installed a “defeat device” that skewed its vehicles’ emissions readings whenever they were being tested. This came as the car company was proudly promoting the low emission levels of its lineup.

Volkswagen first tried to write the discovery off as testing “irregularities” before finally admitting that it installed improper software in more than 11 million of its vehicles. 

In the settlement, Volkswagen agrees to fix or buy back approximately 80,000 3.0 liter diesel-engine vehicles sold in the U.S. It’s faced with a potential payout of $4.04 billion if regulators don’t approve their bid to fix the vehicles affected. 

The settlement – which must be approved by a judge before moving forward – will compensate owners of 3.0 liter vehicles between $7,000 and $16,000 to fix their vehicles. If the fix affects a vehicle’s performance, VW will pay an additional $500. 

Meanwhile, the Bosch payout will pay $163.3 million to 2.0 liter vehicle owners and $113.3 million to 3.0 liter owners. Owners of 2.0 liter vehicles will receive $350 each, and individuals who own a 3.0 liter will each receive $1,500. 

Bosch denies any liability or wrongdoing in the scandal now known as “Dieselgate,” but it says that it settled in order to focus on the “transformation process” the company is now experiencing. 

The lead lawyer for the plaintiffs, Elizabeth Cabraser, said that the Dieselgate settlement will result in "substantial benefits to both consumers and the environment."

Rare <a href="http://www.earth.com/news/dinosaur-collagen-discovery/">dinosaur</a> protein discovered. When dinosaur remains turn into fossils, all of the hard bits – the bones and teeth – slowly transform into a rocklike substance. Scientists rarely get to study the soft tissue, but rather the impressions left in the surrounding material. 

That’s why researchers are excited about the discovery of ancient dinosaur proteins that date back to 195 million years ago. The tissues were found inside a dinosaur bone and were discovered alongside small amounts of a mineral that likely came from the blood of Lufengosaurus, a plant-eating dinosaur from the early Jurassic period. 

Scientists from the<a href="https://www.utm.utoronto.ca"> University of Toronto Mississauga</a> examined the fossils in Taiwan before publishing their findings in the journal<a href="http://www.nature.com/ncomms/"> Nature Communications</a>. They used infrared spectroscopy with a synchrotron to find bits of collagen and proteins within blood vessels inside the dinosaur’s rib bones. 

Because sorts of materials don’t typically survive the fossilization process, the discover sheds more light on how <a href="http://www.earth.com/news/fossils-mean-life-evolved-earth/">fossils</a> form. It also paints a larger picture of the creatures themselves. 

"We hope to be able to learn more about the biology of these animals and the more we know about their soft tissues the more we will know about them overall,” said Robert Reisz, a paleontologist on the research team. “We are actually looking at the preservation of the original materials that were in the living organism rather than an impression of the soft tissues that were there."

There have been other cases in which researchers have reported finding proteins in dinosaurs dating back as far as 70 million years. Stephen Brusatte of the<a href="http://www.ed.ac.uk"> University of Edinburgh</a> was not involved in the research, but told BBC News this discovery “opens up entirely new avenues for studying dinosaurs.”

"This discovery tells us that yes, you really can probably preserve soft, microscopic proteins inside dinosaur bones for tens or hundreds of millions of years,” he said. This rare dinosaur protein has opened up a world of opportunities for paleontologists.

In the first week of Donald Trump’s presidency, he signed a number of executive actions having to do with issues that relate to nature and science. Among them are measures to speed up construction of the Keystone XL and Dakota Access Pipelines. His administration has also issued media blackouts on federal agencies such as the<a href="https://www.epa.gov"> EPA</a> and the <a href="https://www.doi.gov">Department of the Interior</a>. Despite taking these actions, Trump has yet to choose a science advisor. 

Trump currently has no nominees for the role, officially known as the Director of the <a href="https://www.usa.gov/federal-agencies/office-of-science-and-technology-policy">Office of Science and Technology Policy</a>. The person who fills the position will be charged with supplying the President with information necessary to develop educated policy decisions surrounding scientific issues.

In addition to the science advisor position remaining open with no nominees in sight, the Trump transition team has only met once with the OSTP office since the election. This overall lack of concern signals to those in the science field that such issues will not be at the forefront of the Trump agenda. 

This comes in sharp contrast to the previous administration. President Obama chose John Holdren, the current OSTP director, over a month before taking office. 

While the scientific community is concerned with the lack of attention that’s being given to filling the role, they’re also concerned with the names that are being floated as possible nominees. David Gerlenter, a computer scientist at Yale University and physicist William Happer of Princeton University are real possibilities. Both firmly deny that climate change has any basis in science – a concerning position for someone who advises the President on <a href="http://www.earth.com/news/rogue-social-media-trump-resistance/">environmental policy</a> issues. 

Trump’s delay in filling the position is reminiscent of the actions taken (or lack thereof) by President George W. Bush, who didn’t select OSTP director until the June after he took office. The OSTP and issues on which it advises were similarly put on the back burner during the Bush administration.

Oldest human ancestor revealed. When you look through <a href="http://www.earth.com/news/chimps-family-opposites-attract/">family</a> photos, it’s often easy to see where you got your blue eyes or turned-up nose. It may come as a surprise, then, that none of us resemble the creature that scientists are calling our oldest human ancestor.

Known as Saccorhytus, traces of the <a href="http://www.earth.com/video/french-bulldogs-craze/">animal</a> were found preserved as a 540-million-year-old fossil. Despite its age, scientists said the fossil was “exquisitely well-preserved.” The tiny being was only about a millimeter in size – so small that it lived between grains of sand at the bottom of the sea. 

<a href="https://www.cam.ac.uk">University of Cambridge</a> professor Conway Morris, who led the research team, spoke to<a href="http://www.bbc.com/news"> BBC News</a> about their discovery. “To the naked eye, the fossils we studied look like tiny black grains,” he said, “but under the microscope the level of detail was jaw-dropping.” Their findings were published in the journal<a href="http://www.nature.com/nature/journal/vaop/ncurrent/full/nature21072.html"> Nature</a>. 

While it may seem odd that our earliest <a href="http://www.earth.com/video/oldest-human-ancestor-found/">ancestor</a> is a minuscule sea creature, Saccorhytus was one of the steps in the evolutionary process that created fish, as well as humans. It belongs to a category of animals called “deuterostomes.”  This group includes animals such as sea cucumbers and urchins. Its name, which means “second mouth,” refers to a developmental process in which the anal opening develops before the mouth. (Too much information? Let’s move on.) In short, vertebrates are all deuterostomes. 

Despite its being a deuterostome ancestor, scientists can only find an oral opening on Saccorhytus. “Our material is generally crushed, and despite the superb preservation we might have overlooked the evidence,” Morris said to the<a href="https://www.nytimes.com"> New York Times</a>. 

If, in fact, there isn’t an additional opening, researchers believe that the creature ate and excreted waste through the one orifice. (Still too much info. Right.) 

Saccorhytus had a symmetrical body and seems to have moved by contracting its muscles and wriggling around. Scientists also note that it had tiny conical structures that were possibly an early form of gills.

Most noteworthy, though? Its large mouth, which it used to suck in food particles before digesting them and…  Well, you know.

While California’s long <a href="http://www.earth.com/image/southern-california-drought-continues/">drought</a> isn’t over, a pair of rainstorms that ripped down the West Coast may have gone a long way towards repairing the water shortage. Scientists believe powerful storms that swept California from December through January have likely refilled a whopping 37% of California’s snow-water deficit.

The team from the <a href="http://www.colorado.edu">University of Colorado</a> at Boulder analyzed rainfall totals from two recent storms over the Sierra Nevada region. The storms dropped nearly 17.5-million acre feet, or 21.6 cubic kilometers of water on the mountain range. 

Scientists determined this amount by looking at data from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS), a device located on NASA’s Aqua and Terra satellites. They also looked at a computer model drawn up by the University of Colorado and the Jet Propulsion Laboratory at <a href="https://www.nasa.gov/">NASA</a>, as well as data from <a href="http://www.water.ca.gov/">California Department of Water Resources</a> snow sensors. 

These numbers are noteworthy because they total more than 120% of the average snow accumulation for the area in the pre-drought time before 2012. From 2012 to 2016, California began experiencing an average annual snow-water deficit of nearly 10.8 million acre feet (13.3 cubic kilometers). This added up to 54 million acre feet (67 cubic kilometers) over that period. 

The storms that dumped large amounts of rain over California this winter are known as “atmospheric rivers.” These send huge amounts of moisture from the tropics to the west coast of the U.S., resulting in heavy rain and snowstorms. The Pineapple Express is an example of one of these atmospheric rivers. 

Although the new numbers are promising, Noah Molotch, leader of the study, says that one rainy winter season won’t be enough to make up its water deficit. 

"When the snow stopped falling five years ago, the state had to tap into its groundwater reserves to keep up," he said. "One snowy winter won’t be able to entirely reverse that, but there is, at least, some cautious optimism.”

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."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes a new self-powered nanosensor that can instantly detect mercury contamination with the tap of a finger.&nbsp;



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.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.

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

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://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.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."

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.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes a new map of Mars that is providing insight into the planet’s watery past. The map also reveals where future missions could safely land on Mars.&nbsp;



The map has been created over the last decade using observations of water-rich rocks and mineral deposits. The images were captured by ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter.



"A big surprise is the prevalence of these minerals, with the map revealing hundreds of thousands of water-affected locations in the oldest parts of the planet," says ESA. "The new data will help answer exciting questions about Mars’ climate history, whether water was globally persistent or confined to short, intense episodes, and whether the conditions were ever suitable for life."



"Specifically, the map shows the locations and abundances of aqueous minerals. These are from rocks that have been chemically altered by the action of water in the past, and have typically been transformed into clays and salts."



According to John Carter of the Institut d’Astrophysique Spatiale (IAS), our collective understanding of Mars has been oversimplified. He explained that planetary scientists have tended to think that only a few types of clay minerals on Mars were created during its wet period, then as the water gradually dried up, salts were produced across the planet.



The new map shows that the composition of Mars is much more complicated than what we thought. For example, while many salts formed after Martian clays, there are some salts that are presumed to be older than some of the clays.&nbsp;



“The evolution from lots of water to no water is not as clear cut as we thought, the water didn’t just stop overnight. We see a huge diversity of geological contexts, so that no one process or simple timeline can explain the evolution of the mineralogy of Mars. That’s the first result of our study. The second is that if you exclude life processes on Earth, Mars exhibits a diversity of mineralogy in geological settings just as Earth does,” said Carter.

Today's Video of the Day from the <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes how cavefish adapted to a sedentary lifestyle over tens of thousands of years. 



The experts found that the muscle metabolism of cavefish has been genetically reprogrammed over time. As a result, the animals have experienced major changes in their morphology and behavior. Despite these changes, however, the cavefish remain healthy and fit.



The research may provide new clues about the evolutionary consequences of prolonged physical inactivity in humans.&nbsp;



“It’s no surprise that people are moving less and less as technology has advanced,” said Rohner. “With cavefish, we have a unique system where we can study what might happen if people remained couch potatoes over very, very long periods of time.”

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> some of the most incredible waves in the world, as seen by Landsat satellites.



"With more than 370,000 miles of coastline on Earth, there are plenty of places where epic waves build up, curl over, and hurtle toward the shore.- much to the thrill of surfers," says NASA. "There are some places where these waves are so magnificent that they can be seen from space."



"With the broad perspective of satellites, we can see how these iconic waves develop into the world’s tallest, longest, fastest, and heaviest."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes why satellite images and measurements of our planet have become "essential to our survival, offering a new outlook of our world."&nbsp;



Rising sea levels pose one of the biggest societal threats associated with climate change. According to ESA, satellite altimeter missions such as Copernicus Sentinel-6 are essential in monitoring global and regional changes in sea level.



"Unbeknown to many, the island of Crete, Greece, plays an important role in the Copernicus satellite altimetry constellation and on an international stage," reports ESA.



"Satellite altimetry data have to be continuously monitored at the ESA’s Permanent Facility for Altimetry Calibration where different techniques have pioneered the use of transponders to provide the best measurements to validate satellite altimeters in space soon after launch."



Dr. Craig Donlon explains that, by understanding planet Earth through satellite measurements, we are able to find evidence of change.&nbsp;
