High in northern Peru, three frogs no bigger than a thumbprint have stepped out of anonymity and into the scientific spotlight. Their world is a maze of wet cliffs, dripping bromeliads, and wind‑scoured ridges where moss carpets the rocks.



“They’re <a href="https://www.earth.com/news/world-frog-day-2025-protecting-natures-tiny-guardians/">small</a> and unassuming, but these frogs are powerful reminders of how much we still don’t know about the Andes,” said Germán Chávez of the Center for Ornithology and Biodiversity (<a href="https://corbidi.org/">CORBIDI</a>). 



Chávez and his colleagues trekked those ridges between 2021 and 2024, often in freezing rain, to reach calling sites above 9,000 feet.&nbsp;



<h2 class="wp-block-heading" id="h-mountains-support-unique-frog-species">Mountains support unique frog species</h2>



The <a href="https://blog.pensoft.net/2025/06/27/hidden-gems-in-the-mist-three-new-frog-species-uncovered-in-northern-peru/cordillera-de-huancabamba-1/" target="_blank" rel="noreferrer noopener">Cordillera de Huancabamba</a> forms a natural break in the Andes, splitting watersheds and isolating species. 



Ecologists classify the region as a <a href="https://www.cepf.net/sites/default/files/tropicalandes_techsummary.pdf" target="_blank" rel="noreferrer noopener">biodiversity hotspot</a>, one of only thirty‑five on Earth where extraordinary endemism collides with severe habitat loss.



"The Cordillera de Huancabamba is not just a remote range - it's a living archive of biodiversity and cultural legacy," said Wilmar Aznaran. "And we've barely scratched the surface."



Isolation breeds novelty, and novelty fills the genus Pristimantis. With 619 described species, Pristimantis is now the most diverse <a href="https://www.earth.com/news/whistling-forest-frogs-recently-discovered-may-be-wiped-out-before-we-learn-about-them/">amphibian</a> genus on the planet.



The new frogs, Pristimantis chinguelas, P. nunezcortezi, and P. yonke, occupy different niches along the same ridge. One clings to cliff faces, one prowls leaf litter beside clear streams, and the smallest tucks itself deep inside tank bromeliads.



<h2 class="wp-block-heading" id="h-confirming-the-new-species">Confirming the new species</h2>



Night surveys began after dusk, when temperatures hovered near 50 °F and fog erased headlamp beams. Team members listened for faint “peep” notes that barely rose above dripping leaves. 



Finding a caller did not end the chase. Each frog had to be photographed, swabbed for DNA, measured, and released without harming delicate skin.



Back in Lima, the researchers compared mitochondrial 16S sequences. Genetic distances exceeded the three‑percent threshold herpetologists often use to flag separate <a href="https://www.earth.com/news/missing-frog-species-alsodes-vittatus-resurfaces-after-130-years/">species</a>, clinching the case for formal description.



<h2 class="wp-block-heading" id="h-many-amphibians-are-poorly-studied">Many amphibians are poorly studied </h2>



All three newcomers enter the IUCN books as <a href="https://www.thebhs.org/publications/the-herpetological-bulletin/issue-number-169-autumn-2024/4079-03-how-many-data-deficient-amphibians-are-threatened-iucn-red-list-assessments-for-amphibian-species-previously-classed-as-data-deficient" target="_blank" rel="noreferrer noopener">Data Deficient</a>, meaning scientists lack enough information to judge extinction risk. 



The label sounds neutral, yet recent reassessments show that roughly half of amphibians that start as Data Deficient later prove threatened.



Formal names unlock funding and legal tools that nameless creatures rarely receive. Conservation plans, environmental‑impact statements, and protected‑area budgets almost always hinge on a taxon’s standing in recognized databases.



<h2 class="wp-block-heading" id="h-indicators-of-climate-shifts">Indicators of climate shifts</h2>



The Cordillera de Huancabamba isn't just a biological goldmine, it’s wrapped in layers of folklore. In nearby villages, frogs are often seen as signs of rain or omens tied to agriculture and spiritual beliefs.



This cultural lens makes local communities key allies for conservation. When researchers name <a href="https://www.earth.com/news/frogs-lead-the-way-in-developing-new-antibiotics/">species</a> after regional icons or traditions, like P. yonke, they honor local identity and encourage stewardship.



Unlike most frogs, species in the <a href="https://www.inaturalist.org/taxa/64811-Pristimantis" target="_blank" rel="noreferrer noopener">Pristimantis genus</a> bypass the tadpole stage entirely. They hatch from eggs as fully formed froglets, ready to climb, hop, and call without ever entering water.



This reproductive shortcut allows them to thrive in places where standing water is rare or seasonal. It also makes them sensitive indicators of climate shifts and microhabitat changes in mountain ecosystems.



<h2 class="wp-block-heading" id="h-frog-species-in-fire-prone-habitats">Frog species in fire-prone habitats</h2>



Each frog occupies an area smaller than four square miles, hemmed in by crop fields and fire scars. Peru recorded about 10,400 wildfires in 2024, more than double its previous record, burning grasslands and cloud‑forest edges alike.



P. chinguelas calls from a road‑cut cliff where charred bamboo still smells of smoke. P. nunezcortezi shares a single stream corridor that now borders new potato plots.



P. yonke lives higher, inside bromeliads at roughly 9,800 feet, in what locals call the <a href="https://lacgeo.com/northern-andean-paramo" target="_blank" rel="noreferrer noopener">páramo</a>, a chilly grassland‑wetland mosaic perched above the treeline. 



Páramo vegetation stores water like a sponge, so every lost bromeliad weakens both the frogs and the human communities farther down‑slope.



“Exploring this area is more than fieldwork - it’s an immersion into wilderness, culture, and resilience,” said Karen Victoriano‑Cigüeñas.&nbsp;



"Many of these mountain&nbsp;ridges&nbsp;are isolated, with no roads and extreme terrain," noted Ivan Wong. "The weather shifts within minutes, and the steep cliffs make every step a challenge. It's no wonder so few scientists have worked here before. But that's exactly why there's still so much to find."



<h2 class="wp-block-heading" id="h-protecting-the-new-frog-species">Protecting the new frog species </h2>



No one has recorded the breeding calls of P. nunezcortezi or P. yonke, so females remain unverified. Diet, predators, and lifespan also remain mysteries for all three species.



Future expeditions will test whether the frogs persist on neighboring ridges or whether each ridge hosts its own micro‑endemic. 



Acoustic monitors and <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2019.2353" target="_blank" rel="noreferrer noopener">eDNA traps</a> could reveal silent populations hiding in moss tunnels or bromeliad tanks beyond the reach of hikers.



For now, the frogs depend on local goodwill. Community fire patrols, low‑impact grazing, and small protected micro‑reserves can buy time while researchers gather the missing data.



The study is published in the journal <a href="https://evolsyst.pensoft.net/article/148522/" target="_blank" rel="noreferrer noopener">Evolutionary Systematics</a>.

Three new frog species found in Peru face an uncertain future

High in northern Peru, three frogs no bigger than a thumbprint have stepped out of anonymity and into the scientific spotlight. Their world is a maze of wet cliffs, dripping bromeliads, and wind‑scoured ridges where moss carpets the rocks. “They’re small and unassuming, but these frogs are powerful reminders of how much we still don’t know about the Andes,” said Germán Chávez of the Center for Ornithology and Biodiversity (CORBIDI).

The population of seabirds on a British island has made an impressive recovery after a project was launched to eradicate thousands of rats that were eating all the bird eggs. 

In less than two decades, the number of puffins on Lundy Island has bounced back from less than 20 to 375 birds. The project has also boosted the population of Manx shearwaters from hundreds to thousands. 

According to the <a href="https://www.rspb.org.uk/">Royal Society for the Protection of Birds</a> (RSPB), the total number of seabirds on Lundy has tripled to 21,000 in the 15 years after the rats were removed. The RSPB, which is a wildlife charity in the UK, said the initiative has been a great success. 

"This study clearly shows how quickly and positively seabirds respond to the removal of non-native predators," said Helen Booker, who is RSPB's senior conservation officer. "Of course, we had anticipated major population increases when the project was launched, but the scale of this recovery has far exceeded our expectations."

In 2003, efforts were launched to get rid of the rats on Lundy Island in a collaboration among the RSPB, Natural England, the Landmark Trust, and the National Trust. Ever since the island was declared free of rats, the <a href="http://www.earth.com/news/balloons-biggest-threat-seabirds/">seabird populations</a> have been steadily increasing. 

"It is exciting to see this level of recovery in Manx shearwaters, one of our most important seabirds," said Dean Jones, who is the warden on Lundy Island. "In spring the island comes alive at night with the sound of these amazing birds."

"The increases in puffins, guillemots and razorbills is also very encouraging for the future of seabirds on Lundy and we are maintaining our vigilance to ensure rats cannot return to the island."

Scientists are working to gain a better understanding of the genetic makeup of wolves that are isolated on Isle Royale, which is one of the most remote national parks in the United States located in Lake Superior. 

Researchers led by <a href="https://www.mtu.edu/">Michigan Technological University</a> studied the genes of one particular pair of wolves and discovered they were father and daughter, yet shared the same mother. According to the experts, this type of close inbreeding causes abnormalities that likely contributed to the crash of the Isle Royale wolf population over the last decade. 

In the absence of wolves, the moose population has become detrimental to many other species by wiping out much of the island's vegetation. To address the issue, the National Park Service has been restocking wolves on the island. Last fall and winter, 13 new wolves were introduced from the mainland.

The researchers are describing how homozygosity, or the possession of two identical strains of the same gene, could have caused the inbreeding depression among the Isle Royale wolves. When a gene is homozygous, uncommon traits that are usually recessive often become dominant. In this case, inbreeding led to deleterious recessive mutations causing spinal deformities and other health problems.

"This new study, including whole-genome analysis of wolves from Isle Royale, directly links specific candidate genes with spinal abnormalities, which became more prevalent as decades progressed and inbreeding became more severe," explained study co-author and research scientist Rolf Peterson.

The wolves on Isle Royale may be an extreme example, but an understanding of population genetics is needed to inform future conservation efforts elsewhere. The genetic makeup of the wolves can be used to investigate how their reintroduction affects the overall population. The research will also help conservationists meet the increasing challenges of fragmented habitats and genetic pools around the world.

The study will be published next week in the journal <a href="https://advances.sciencemag.org/">Science Advances</a>.

Crowdsourcing has become an incredibly popular tool. Books, movies, medical procedures have all been paid for by people donating small amounts online combined into a ‘crowd’ of people donating a large amount. It isn’t just direct monetary donations either, as data is harvested by millions of people worldwide to benefit businesses and political campaigns. Increasingly, little bits of money, data or time from large groups of people are being funneled through the internet to create real world results. This is now true even in conservation biology. 

<a href="https://www.zooniverse.org">Zooniverse</a> is a research platform that utilizes volunteers on the internet to collect data for scientific projects. The types of projects vary and are created by a number of different researchers. For instance, <a href="https://www.zooniverse.org/projects/sandiegozooglobal/wildwatch-burrowing-owl/about/research">Wildwatch Burrowing Owl</a> asks on its homepage, ‘Will you help us save burrowing owls?’ The question refers to the iconic burrowing owl that takes over <a href="https://www.earth.com/news/prairie-dogs-true-underdog/">prairie dog</a> and other burrowing mammal dens as its home, an increasingly rare icon of the western deserts and prairie. It’s estimated that there are only 10,000 breeding pairs of the special owl left, according to <a href="https://defenders.org/burrowing-owl/basic-facts">Defenders of Wildlife</a>. 

Western burrowing owls (Athene cunciularia hypugaea) in California are especially in decline. To stop this decline, <a href="https://www.sandiegozooglobal.org/">San Diego Zoo Global</a> has set up artificial dens for the owls as well as reintroduction of ground squirrels. The ground squirrels dig their own burrows that are eventually taken over by burrowing owls.

The burrowing owl project has motion cameras set up at the borrows to monitor who is coming and going from the burrows. Cameras like these collect hundreds if not thousands of photos in a short amount of time. Many photos from cameras like these inevitably aren’t even of the animals being studied, and sometimes a camera takes a shot of another animal, a person or even grass moving in the wind. Because of the amount of photos to sort through, the platform on Zooniverse allows untrained volunteers working at home on their computer to donate whatever time they’d like to sorting through the owl photos. The goal is to note how many owls are in each photo, allowing researchers to sort through the data faster than if they did the work themselves. 

Other projects on zooniverse include similar projects with large mammals in <a href="https://www.zooniverse.org/projects/pangorilla/wild-gabon">Gabon</a>, Africa, <a href="https://www.zooniverse.org/projects/penguintom79/penguin-watch/about/research">penguins</a> in Antarctica and even <a href="https://www.zooniverse.org/projects/lawildlife/wildlife-of-los-angeles/about/research">urban wildlife</a> in Los Angeles. The penguin project once was even gave away a free trip to Antarctica to a lucky volunteer. Some of these projects like Wildwatch Burrowing Owl are directly related to conservation, others less so, but they all potentially contribute data that can be used by wildlife managers. Zooniverse isn’t the only way you can contribute to science or conservation from home, though.

Of course if you have specific skill sets, you can be more valuable to organizations or causes as a volunteer, and this is as true with volunteering time online as it is volunteering in person. If you have knowledge of law, computer programming or writing skills for example, you may be able to contribute real assistance to non-profits without ever leaving home. 

Like Zooniverse, <a href="https://taprootfoundation.org/nonprofits/?utm_source=&amp;utm_medium=&amp;utm_campaign=&amp;utm_term=&amp;utm_content=">Taproot Foundation</a> is an online platform allowing non-profit organizations to seek volunteers. Unlike Zooniverse, most of these organizations are seeking one or two skilled volunteers to help on a limited time project. The focus is also much broader than Zooniverse and virtually any sort of non-profit can be involved in Taproot. You can do work such as consulting, writing, web design or even phone work for a non-profit from home.

Because of the nature of the volunteer positions listed on Taproot, projects you can become involved with are always changing. A nice feature is that you can sign up for an account with Taproot, listing your skills and interests and when a project that seems like a good match comes up, you get emailed a link to see if you’re interested. Of course, if you’re interested in a serious internship in conservation to build your skills or want to be involved in a long term project, most of these shorter projects might be less satisfying. 

Occasionally, online jobs in wildlife biology or conservation come along that actually pay. For example, <a href="https://wfscjobs.tamu.edu/jobs/acoustic-recording-bird-song-identifier-various-locations/">some academic institutions</a> seek out a person with exceptional birding skills to identify birds by the sound of their calls from home for a short contract period. Others may be lucky enough to find longer term employment in the same vein. There are also plenty of nature and science publications that might take you on as a writer or intern if you have writing abilities and a story to tell. Other online volunteer positions are to help people access natural history interpretive material.

The <a href="https://www.amnh.org/">American Museum of Natural History</a> is taking on volunteers for <a href="https://projectdescribe.amnh.org/#/">Project Describe</a>. The project involves describing items in the museum’s collection of images on their website so that these images are more accessible to those with disabilities. The Smithsonian Institute also takes <a href="https://transcription.si.edu">online volunteers</a> for many of its museums. The work for the Smithsonian involves transcribing photos of labels in an attempt to make more material available online. For those interested in biodiversity, volunteer positions are available in entomology, invertebrate zoology, botany at the Smithsonian Tropical Research Institute (which includes a famous research station in Panama). 

Projects that still need assistance can be found in the <a href="https://transcription.si.edu/browse?filter=collection%3A2&amp;sort=">Biodiverse Planet</a> category. Helping museum work may or may not contribute directly to the environment, but it least is helping to educate the public about the environments we live in and the wildlife we share them with. 

In the end, volunteering online can help you learn a bit about animals or science and help organization or researchers out, but it can also feel a bit isolating. For some experiences, there’s no substitute for getting outside into the actual environment and interacting with it. After all, there is no wildlife living online, there are no outdoor places in your computer. Often there is no mystery or surprise in sorting through images or labels on a home computer. Much like reading a book, volunteering online can be a part of learning about the world... but it shouldn’t be the only part.

Wolf-dog <a href="https://www.earth.com/news/extinct-red-wolf-dna-texas/">hybrids</a> have become so numerous in Europe that there are now concerns that the hybrid animals could drive wolf populations to extinction. 

In a new study published in the journal Frontiers in Ecology and Evolution, researchers from the <a href="https://www.exeter.ac.uk/">University of Exeter</a> warn that wolf-dog “swarms” are overtaking purebred wolves. 

Both wolves and dogs are members of the genus Canis which means that the two species can interbreed and produce offspring. 

Habitat loss due to urban expansion and other human activities are making wolf and free-roaming dog encounters more frequent. 

More than 40 scientists with a range of backgrounds and expertise weighed in on the issue, and although the majority consensus is that hybridization is a problem, no one can agree on a solution. 

“We need to address this issue before wolf-dog hybrids backcross with wolves to the extent that wolf populations will be lost to hybrid swarms, and the conservation of wild populations will become unfeasible,” said Valerio Donfrancesco, the lead author of the study. “In this paper, we argue that scientific agreement is crucial to encourage decision-makers to act, and to raise awareness about this conservation issue in society at large.

For the study, scientists were given the opportunity to share their views on the issue anonymously. 

It was agreed that free-roaming dogs are a big part of the problem and that wolf-dog hybrids should be kept away from wolf populations. 

However, when it came to suggestions for how to prevent wolf-dog hybrid encounters, the results were mixed. Some scientists supported the idea of keeping hybrids and dogs captive, or sterilizing free-roaming dogs to prevent reproduction, while others even recommended killing hybrids. 

The lack of research dedicated to wolf-dog hybrids further emphasizes the complex issue, but this should not dissuade action, the study authors say. 

“We hope that by highlighting areas of disagreement and why they occur, we will be able to build a more unified scientific opinion, and aid an effective management of this urgent issue,” said Dr. Nibedita Mukherjee, a co-author of the study.

When a fight occurs between two <a href="https://www.earth.com/news/competing-mate-sperm-quality/">competing animals</a>, the loser of the battle often avoids violent altercations for some time. This is called the “loser effect,” and a new study shows that fighting ability does not affect how soon an animal returns to fight off others. 

Researchers from the <a href="https://www.exeter.ac.uk/">University of Exeter</a>, <a href="http://www.okayama-u.ac.jp/index_e.html">Okayama University</a> and <a href="https://www.tmu.ac.jp/english/index.html">Tokyo Metropolitan University</a> studied and selectively bred captive beetles to understand how the loser effect evolves in a species. 

The findings were published in the journal Proceedings of the Royal Society B. 

Broad-horned beetles fight over females, and once a beetle lost a battle, most would not start another fight for about four days. 

However, after selectively breeding the beetles to lose the “loser effect,” the beetles started fights sooner even though their fighting ability had stayed the same. 

In other words, the loser effect is not determined by fighting ability, and the two evolve independently. 

“By selecting males who experienced the loser effect for the shortest time, we were able to breed beetles willing to fight again sooner,” said David Hosken, a member of the research team. “It is fascinating that these males were no better at fighting. In other words, there is a complete disconnect between actual fighting ability and the duration of the loser effect.”

For the study, the researchers paired males together to see how they interacted for an hour. A winner was determined if the beetle had pushed or chased away his opponent. 

Next, the researchers took the beetles that were less impacted by the loser effect, and after ten generations, loser beetles returned to fight other males after three days rather than four despite having the same fighting abilities. 

The study shows that past experiences and losses determine future decisions for some species rather than actual fighting ability. 

“It makes sense for animals to use past experience to decide whether to engage in a behaviour,” said Kensuke Okada, an associate professor at Okayama University. “Losing a fight is a useful clue of the likely benefits of further fighting for a particular individual. Some species also show a ‘winner effect’ - being more willing to fight after a victory - but that is not the case among broad-horned flour beetles.”

Fighting ability does not impact how soon a beetle gets back in the ring

When a fight occurs between two competing animals, the loser...

Most people are well aware of the impressively long distances covered by some butterflies. Monarch butterflies (Danaus plexippus) migrate up 2,500 miles each year between cold and warm habitats. How the migration started is hard to know but it gives obvious benefits to the butterfly and allows wonderful spectacles for humans to enjoy. 

According to the <a href="https://www.fs.fed.us/wildflowers/pollinators/Monarch_Butterfly/migration/index.shtml">United States Department of Agriculture</a> (USDA), eastern populations of monarch butterflies overwinter in oyamel forests in the eastern Sierra Madre range of Mexico. Mainly these butterflies are known for their wintering grounds in the <a href="https://www.fs.fed.us/wildflowers/pollinators/Monarch_Butterfly/conservation/index.shtml#monarca">Monarch Butterfly Biosphere Reserve</a>, founded in 1986 in the Mexican state of Michoacan. The western population of monarch butterflies overwinters in California. As we’ve reported, there has been some <a href="https://www.earth.com/news/monarch-butterflies-winter-locations/">recent evidence</a> that monarch butterflies have been finding other places to overwinter as well. What is surprising is how far afield monarch butterflies have made it. 

Monarch butterflies were potentially caught in a storm and blown far out to sea where the tired and battered insects found a small island to make home. No one knows for sure if this is how it happened. It’s possible that a person carried a monarch knowingly or on accident with them to a Pacific island. What is known is that at some point in the not too distant past, monarch butterflies colonized islands in the Pacific Ocean. 

From the islands in the Pacific, it was less of a jump to colonize other parts of the world. According to <a href="http://cookislands.bishopmuseum.org/showarticle.asp?id=21">Cook Island Biodiversity &amp; Natural Heritage</a>, the monarch butterfly is the largest of the native species of butterfly in the Cook Islands. Despite its recent arrival, the monarch is called native in this context because it probably arrived under its own power. 

Animals, plants and other organisms have always moved from one place to another, colonizing or invading new lands, depending on perspective. Interestingly though, the monarch butterfly migration isn’t so simple. For the butterflies to move, so did their host plants, the milkweeds. Milkweed plants are full of toxic alkaloid compounds that mother monarch butterflies taste the plants for before depositing eggs on a host. 

The monarch caterpillars ingest the alkaloid compounds when feeding on the plant for a very important purpose. Birds often eat butterflies. A brightly colored butterfly such as a monarch, slowly flapping through a sunlit meadow seems like an easy target for a hungry robin or blue jay. However, the bright colors of the monarch wings are a warning that they’re not too tasty. In fact, the monarchs secrete the alkaloids they ingest into their skin, making them bitter and poisonous. The poison is a potent protection for monarchs. 

Birds were fed monarch butterflies in a <a href="http://images.peabody.yale.edu/lepsoc/jls/1960s/1964/1964-18(3)165-Petetersen.pdf">famous experiment</a> carried out by researchers at <a href="https://www.colorado.edu/">UC Boulder</a>. The birds vomited violently after eating them and refused to try the butterfly again. Even butterflies that look similar to monarchs but don’t dine on toxic plants are avoided by hungry birds. Without the presence of the milkweed, it’s unlikely that birds in new places would ever learn the meaning of the monarch’s bright wings, making them an easy meal. So before monarchs could spread to Pacific islands, milkweed had to spread. This is why the first record for monarch butterflies in Hawaii is in 1840 or Tonga in 1863. Slowly, the monarch butterfly colonized much of the Pacific following in the wake of transplanted milkweed.

Eventually, monarchs arrived on the largest landmass in the South Pacific – Australia. The first record of monarch sightings in Australia come from the summer of 1870-71, according to <a href="https://www.abc.net.au/radionational/programs/offtrack/flying-weeds:-how-the-monarch-butterfly-colonised-australia/6768228">ABC</a>, when several sightings were recorded. 

The fact that there were several sightings all at once indicates that the butterfly was probably already established in Australia. It’s impossible to know when the first monarch actually alighted on the Australian continent but it’s possible that the butterfly blew in from New Caledonia, where today monarchs still live with two other butterfly species in the same genus. Interestingly, monarch butterflies in their expanded range have shown themselves to be quite adaptable. In Australia, the species is rightly called the ‘<a href="https://australianmuseum.net.au/learn/animals/insects/wanderer-butterfly/">wanderer butterfly</a>’ due to the roaming nature that allows it to migrate such long distances and that originally brought it to Australia in the first place.

In the more northern parts of eastern Australia where monarchs live, they migrate to the warmer coastal areas during the winter and move more inland during the summer, according to <a href="https://australianmuseum.net.au/learn/animals/insects/wanderer-butterfly/">Australian Museum</a>. In warmer areas of Australia, the monarchs breed nearly continuously throughout the year, with a large overlap between generations occurring which is unusual in North America. In the southern part of Australia where temperatures are cooler, monarchs don’t mate immediately when they mature in the fall. Instead southern Australia monarch butterflies overwinter, sometimes in large groups as in North America and mate in the warmer months. 

After mating the monarchs fly northward, and after several generations arrive in the northern part of their range, a similar life history to the butterflies in North America. Interestingly in Australia, there appear to be a few birds immune to the monarch butterfly poisons Pied Currawongs (Strepera graculina) and Black-faced Cuckoo-shrikes (Coracina novaehollandiae) have been seen eating monarchs without apparent illness. Monarchs even on occasion have been found wandering in Tasmania, although they’re a rare visitor. Monarchs in other parts of their new homes also migrate.

In New Zealand, large groups of monarch butterflies overwinter. Enough butterflies have been overwintering in large groups at Tauranga Bay that the <a href="https://www.monarch.org.nz">New Zealand Monarch Butterfly Trust</a> was originally formed to protect the site. Like in parts of Australia, New Zealand monarch butterflies generally overwinter in coastal areas where temperatures are mild and move inland to mate and lay eggs in the summer. Unfortunately, troubles have followed the wandering butterfly.

Pesticides, deforestation, pesticide use and disappearance of milkweed have lowered the monarch butterfly populations in North America. Unfortunately, the same things as well as climate change and perhaps an occasional random storm have hurt the monarch populations in Australia, according to <a href="https://theconversation.com/iconic-monarch-butterflies-under-threat-from-rising-herbicide-use-27596">The Conversation</a>. Humans are partially responsible for the global success of monarch butterflies, but tragically we may be the ones to put an abrupt end to it as well.

Gray whales have been <a href="http://www.earth.com/news/whales-washed-ashore-san-francisco/">turning up dead</a> in alarming numbers along the western coast of the United States from California up to Washington. Scientists believe they are starving to death as they make their annual journey from Mexico to Alaska, but the conditions driving the lack of food remain unknown.

So far this season, 61 dead gray whales have washed up along the shoreline. According to the experts, most of the animals showed signs of malnutrition, and autopsies revealed that some had starved to death. 

"Clearly something is going on with the forage, as these animals’ tanks of gas are either empty or very low," said Justin Viezbicke of the <a href="https://www.noaa.gov/">National Oceanic Atmospheric Administration</a> (NOAA).

This is not the first time that there was an unusual number of gray whales found stranded on the west coast. In 1999 and 2000, the bodies of more than 600 whales were recovered. Experts at NOAA considered many possible causes including starvation, chemical contaminants, biotoxins, infectious diseases, parasites, fisheries interactions, and ship strikes.

"While the emaciated condition of many of the stranded whales supports the idea that starvation could be a significant contributing factor in these mortalities, the underlying cause of starvation during this event is unknown," <a href="https://www.afsc.noaa.gov/techmemos/nmfs-afsc-150.htm">stated</a> NOAA.

This year, the actual number of whales affected is likely much higher than what is realized because only about 10 percent of the bodies make it to the shore.

The gray whales are in the middle of their migratory season, during which they travel thousands of miles to the nutrient-rich waters of the North Pacific and the Arctic where they feed in the summer months. 

Scientists are investigating whether there is simply not enough food available for the whales and if this mortality event may be tied to climate change. The Arctic is extremely susceptible to climate change, and the changing conditions may be impacting the food chain. 

"Climbing temperatures have begun melting ice that used to be impassable," states the Scripps Institution of Oceanography. "In the Arctic, this increases competition for food as more fish migrate through areas where gray whales historically feed upon crustaceans, plankton, and mollusks that they dredge from the ocean floor."

An international team of scientists has determined that the rate of <a href="http://www.earth.com/news/ivory-poaching-elephants-tusks/">elephant poaching</a> in Africa is now declining after reaching its peak in 2011. The researchers said that the world's elephants will remain threatened, however, until more action is taken to address poverty and corruption and there is a drop in the demand for ivory. 

"We need to reduce demand in Asia and improve the livelihoods of people who are living with elephants in Africa; these are the two biggest targets to ensure the long-term survival of elephants," said Dr. Beale. "While we can't forget about anti-poaching and law enforcement, improving this alone will not solve the poaching problem."

The study, which was led by the <a href="https://www.york.ac.uk/">University of York</a>, has revealed that the annual mortality rate from poaching dropped from 10 percent in 2011 to four percent in 2017. There are an estimated 350,000 elephants left in Africa, but as many as 15,000 are killed by poachers every year. At the current rate of poaching, elephants could almost completely vanish, with the few survivors living in small, protected populations. 

"We are seeing a downturn in poaching, which is obviously positive news, but it is still above what we think is sustainable so the elephant populations are declining," said study co-author Dr. Colin Beale. "The poaching rates seem to respond primarily to ivory prices in Southeast Asia and we can't hope to succeed without tackling demand in that region."

According to the study authors, it is impossible to know the impact of the ivory trade ban that China introduced in 2017. They pointed out that ivory prices started to fall before the ban and may reflect a broader downward trend in the Chinese economy.

"Ensuring a future with wild elephants, and myriad other species, will require stronger laws and enforcement efforts and genuine community engagement; however, as long as demand exists supply will find a way to quench it," explained study co-author Lisa Rolls Hagelberg. "Only about 6% of the current funding going towards tackling illegal trade in wildlife is directed to communication."

"For long-term success, governments need to prioritize comprehensive social and behavioural change interventions to both prevent and reduce demand. We have the know how, now we need to invest to truly influence environmental consciousness."

The study is published in the journal <a href="https://www.nature.com/ncomms/">Nature Communications</a>.

While poaching rates have dropped, elephants are still far from safe

An international team of scientists has determined that the rate...

The last male Sumatran rhino in Malaysia has died of liver and kidney damage, the <a href="http://www.borneorhinoalliance.org/">Borneo Rhino Alliance</a> (BORA) confirmed. The rhino’s name was Tam and he was believed to have been in his 30s.

Sumatran Rhinos were declared extinct in the wild in 2015 in Malaysia, with only three small populations remaining in Indonesia. The small rhinos population has declined by 70% in the last twenty years. 

Tam was captured in a palm oil plantation at approximately 20 years old in 2008 and relocated to Tabin Nature Reserve where he has lived since, according to <a href="http://www.heraldmalaysia.com/news/malaysia-holds-vigil-the-last-male-sumatra-rhino-is-dying/48003/5">Herald Malaysia</a>. Tam was part of an unrealized breeding program plan in Malaysia. There is only one other Sumatran Rhino in Malaysia, a female, Iman who was captured for captive breeding in 2014 but is now past her reproductive prime, and she has never successfully bred in captivity. 

Iman showed signs of a ruptured tumor in her uterus in 2017. Another female rhino in Malaysia was euthanized in 2011 after suffering from skin cancer. These illnesses seem to be the result of poor genetics from a dwindling population of animals, the death throes of if not a species, a population. The decline of the Sumatran Rhino in Malaysia has been exasperated by neglect from conservationists in Indonesia. 

In modern times, where data is collected on wild animals and they are often kept in cages, it’s much easier to notice the passing of a species. Sometimes it comes down to the death of one, iconic individual animal. Martha was the name of the last known passenger pigeon, who was kept in the Cincinnati Zoo until she <a href="https://abcbirds.org/martha-the-last-of-her-kind/">died in 1914</a>. In <a href="https://www.historychannel.com.au/this-day-in-history/the-last-tasmanian-tiger-dies/">1936</a>, a Tasmanian Tiger or thylacine died in the Hobart Zoo in Tasmania. A mechanism designed to allow the animal inside to stay warm failed and apparently the Tasmanian Tiger died from the cold.

Sometimes extinctions like these haunt us. Whether real or not, several sightings have been reported of thylacines after the animal was officially written off as extinct. The more common pigeons easily bring to mind what must have been awe inspiring flocks of passenger pigeons moving like clouds across the sun for entire days. Museums hold the remains of these dead species. Preserved in life-like poses, they become relict for the faithful, but I wonder if these extinctions mean more to us than when a hunter went out and simply no longer found a certain prey. 

Despite the lingering ghosts of the human slaughtered dead, species continue to die. Individuals pass away in undignified cages, prisoners of the same that killed their kin or alone under the sky of their eerily quieted homes. With individuals, so go species. With blood on our hands, we swear to learn from our mistakes and yet, on it goes. The <a href="https://www.biologicaldiversity.org/programs/biodiversity/elements_of_biodiversity/extinction_crisis/">Center for Biological Diversity</a> reports that the rate of extinction is 1,000 times greater than a natural background of extinction. 99% of endangered species are threatened by human activities. The rhinoceroses of Malaysia are no different. 

In 2018, the <a href="http://www.earth.com/news/northern-white-rhino-died/">last male northern white rhino</a> died, signaling the end of a subspecies. The last of his kind, the northern white rhino was named Sudan, he died at the age of 45 in captivity in Kenya, according to the <a href="https://www.bbc.com/news/world-africa-43468066">BBC</a>. The <a href="https://rhinos.org/2018-state-of-the-rhino/">International Rhino Foundation</a> reported that as a species, white rhinos are doing better than many others, with an estimated population of approximately 20,000 animals. Greater One-Horned Rhino populations are on the rise as well, with more than 3,500 animals. Unfortunately, Black rhino populations have dropped drastically but with about 5,000 individuals, there’s still a lot of hope.

Poaching is a huge factor in the decline of rhinoceroses, whose horns are valuable on the black market for traditional Chinese medicine. Despite this, the rhinos in Africa have in some cases grown in population, proof of some successful conservation measures. 

Rhinoceros species in Asia haven’t fared nearly as well as these in Africa. There are perhaps only 67 Javan Rhinos left alive in the world, found only in Ujung Kulon National Park, Indonesia, where they are fiercely protected. Unfortunately, the park is near an active volcano, an eruption could quickly push the Javan Rhino into extinction. The last Javan rhino known to live in Vietnam was found dead with its horn hacked off.  

In 2012, the Indonesian government and several conservation organizations signed an agreement committing themselves to a program of collaboration with Malaysian groups on the conservation of the Sumatran Rhino. Despite efforts on the part of Malaysia, the agreement apparently came to nothing. Now, it seems that the last of Malaysia’s rhinoceroses will soon be gone. 

The <a href="http://www.heraldmalaysia.com/news/malaysia-holds-vigil-the-last-male-sumatra-rhino-is-dying/48003/5">Herald Malaysia</a> reported that Tam stopped eating in April. The passing of Tam represents the end of a slender hope to successfully breed rhinos in Malaysia and save a population there. 

In Indonesia, conservation efforts are still under way. <a href="https://news.mongabay.com/2019/04/to-rescue-sumatran-rhinos-indonesia-starts-by-counting-them-first/">Mongabay</a> reported in February that the Indonesian government aims to officially tally the rhino population within three years, which currently stands at estimates of 30-100 wild animals with several in captivity. The <a href="https://rhinos.org/where-we-work/sumatran-rhino-conservation-program/">International Rhino Foundation</a> reports that it has been involved in creating a Sumatran Rhino Sanctuary as well as sponsoring rhino protection units. The result of the efforts is the prevention of poaching in areas where these units operate for nine years. Along with captive breeding programs in Indonesia as well as collaboration with organizations in the US, there is some hope.

A recent study led by the <a href="https://www.utas.edu.au/">University of Tasmania</a> has revealed that the global fishing fleet grew from 1.7 million vessels in 1950 to 3.7 million in 2015. However, the total catch dropped by more than 80 percent in the same time frame.

According to study lead author Yannick Rousseau, the findings reflect growing pressure on marine resources and a fall in the abundance of <a href="http://www.earth.com/news/tiny-fish-coral-reefs-thrive/">fish</a>.

"What we have seen over the last 65 years is more and more fishing vessels chasing fewer fish," said Rousseau. "Since 1950, a dramatic increase in the size of the fishing fleet in Asia has more than offset small declines in North America and Western Europe."

"Most of the increase in vessel numbers has been in motorized fishing boats, a change from the unpowered 'artisanal' fishing vessels that once characterized Asian and African fishing fleets. But, despite its advanced technology and increased numbers, the modern motorized fleet is having to work much harder to catch fewer fish."

Rousseau explained that scientists use a measure of catch per unit of effort (CPUE) to evaluate fisheries management and the well-being of fish stocks.

"CPUE reflects how many fish are caught for the amount of effort expended, such as during a day's fishing, and this measure paints a dark picture of the state of the ocean's resources," said Rousseau.

"In recent years, a sharp drop in CPUE in Southeast Asia, Latin America and the Southern Mediterranean indicates their fisheries expanded at a much faster rate than fish stocks could support."

In developed countries such as Australia, the researchers found that CPUE has recently stabilized due to more effective fisheries management and a sharp fall in the size of the fishing fleet over the last decade.

"However, on current worldwide trends we can expect to see a further one-million vessels on the water by mid-century and the average engine power of the global fleet continues to increase," said Rousseau. "These changes will further challenge the sustainable use of fisheries resources in coming years."

"This is a particular concern for populations in regions such as Southeast Asia, where a high proportion of people rely on fish for sustenance. Our findings suggest that additional management measures are urgently warranted to ensure the future sustainability of global marine resources."

The study is published in the journal <a href="https://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

Investigation reveals new clues to the evolution of language and communication. In an effort to better understand how <a href="http://www.earth.com/news/brain-storage-learn-language/">human language</a> and communication developed, a team of scientists from the <a href="https://www.leibniz-gemeinschaft.de/en/institutes-museums/einrichtungen/dpz/">Leibniz Institute for Primate Research</a> has analyzed the vocalizations of vervet monkeys. It is known that East African vervets have specific alarm calls to warn for a leopard, eagle, or a snake, and the researchers wanted to investigate the call system used by the closely-related <a href="http://www.earth.com/image/the-gambia-river-in-west-africa/">West African</a> vervets.

To examine how the West African vervets would react to unknown sounds, the researchers flew a drone over a group of monkeys and later played them a sound recording of the drone noise. The reactions of the monkeys indicated that they learned very quickly what the sound of the drone meant. 

However, instead of creating a new vocalization, the animals used the alarm call that East African vervets use to warn of eagles or other aerial predators. According to the study authors, this suggests that the call structure was determined long ago in the course of evolution and has been conserved.

Leopards, eagles, and snakes are the three main predators faced by East African vervet monkeys, and the animals use alarm calls that are followed by a specific strategy. When they hear the call for leopard, for example, they climb a tree. The call for eagle means to search the sky and hide, while the call for snake means to freeze like a statue on two legs.

The West African green monkeys were found to use alarm calls for leopards and snakes, but had not developed a call for aerial predators. When the research team carried out the drone experiment, the animals reacted to the drone sound with alarm calls, searched the sky, and hid. 

"The animals quickly learned what the previously unknown sounds mean and remembered this information," said study lead author Julia Fischer. "This shows their ability for auditory learning."

The calls used by West African vervets closely resembled those used by East African vervets as an eagle approaches. "The structure of the alarm calls seems to be deeply rooted in the evolution of vervet monkeys," explained Fischer. Investigation reveals new clues to the evolution of language and communication

One of the best ways to live with wildlife is to leave as much of the natural habitat around your home as undisturbed as possible. Unfortunately for many of us, we live in an already very disturbed environment with little of the complex ecological interactions found in undisturbed areas left intact. Because of this, it often falls on people to restore or reconstruct what they can of a habitat if they want to have the pleasure of wildlife encounters or simply wish to help non-humans. 

Water is often an incredibly important resource for animals. Living in the desert as I do, it’s easy to see birds bathing in any small puddle of water. I recently watched a hummingbird cleaning herself and splashing in a thin stream of water coming from the top of a small fountain in my neighborhood. It’s also important to realize that using large amounts of water for pools, artificial streams, or fountains can also fly in the face of common sense water conservation methods. 

One option is to collect rainwater, using some of it in pools for wildlife and perhaps even watering a garden, trees or other plants with it. Of course, water collection can go too far. Theoretically someone with hundreds of acres could create a massive personal reservoir that would in turn disrupt the local ecology. Because of this, there are some states with restrictions on how you can collect rainwater. In other areas, the government gives subsidies, encouraging the harvest of precious rainwater. <a href="https://www.newsdeeply.com/water/community/2018/01/09/in-tucson-subsidies-for-rainwater-harvesting-produce-big-payoff">NewsDeeply</a> reported that the city of Tucson, Arizona had given out more than $2 million in rebates to those collecting rain water.

Of course, water isn’t the only resource useful for wildlife or the only factor that creates a habitat. Plants are also very important to most animals. Flowers attract pollinators from bees and butterflies to hummingbirds and even bats. Plants with fruits or tasty leaves also attract a new suite of animals that want to munch in your yard. If you’re not willing to share plants or their fruit with animals, it’s important to protect them in a way that doesn’t hurt wildlife. 

Nets over fruit trees or fences around gardens can often accomplish the task. If you’re ok with rabbits, birds, deer or other wildlife eating plants in your garden, it’s helpful to plant native plants that will attract native wildlife. In a <a href="https://zachofjungle.com/2019/05/11/plant-rescue/">recent interview</a>, Denise Gehring of Wild Ones, a non-profit that promotes natural gardening, highlighted the importance of native plants. Native trees support native insects, which in turn can support native birds and other wildlife. This is why it’s also important to not use pesticides in areas you want to attractive wildlife to – it’s not just about birds and larger animals but also about the insects they eat. Besides eating and drinking, animals also find shelter in their natural habitats. 

Leaving some sticks fallen from trees and rocks in an area is a start, which provide habitat for invertebrates and other small animals like lizards and snakes. Depending on where you live and your attitude, snakes may be a bigger problem than the benefit of providing habitat to other animals. Small amounts of grass, sticks and other debris may also be used by nesting birds besides being used as habitat in situ. According to <a href="https://extension.psu.edu/wildlife-habitat-relationships">Penn State Extension</a>, live trees such as pines provide nesting sites in summer as well as thermal cover in winter. 

It’s also possible to directly build homes for many animals. Nest boxes and bird houses are probably the most obvious examples of building homes for animals and that’s a good start. <a href="https://ir.library.oregonstate.edu/downloads/w66343824">Oregon State University</a> offers instructions on how to do so. It’s surprising how many other animals are willing to live near humans, bats sometimes live in caves but certain species or populations prefer other habitats in which to roost. You can even provide bat houses in your yard, and <a href="https://www.nwf.org/Garden-for-Wildlife/Cover/Build-a-Bat-House">The National Wildlife Federation</a> has detailed instructions on how to build them. 

If you’re concerned about native pollinators such as <a href="https://www.earth.com/news/save-native-bees/">bees</a>, you can also provide space for them to live. Many native bees are not colonial in the same way that honey bees are, so instead living alone in small holes, they sometimes live in holes inside of human structures. Because of this, you can provide places for mainly harmless native bees to live without attracting something that will swarm and harm humans. Attracting native pollinators has the added benefit of helping plants in your garden and perhaps providing more food for birds or other animals. <a href="https://modernfarmer.com/2017/02/build-native-bee-hotel/">Modern Farmer</a> has instructions for building a native ‘bee hotel’. Besides the needs for shelter, food and water, <a href="https://extension.psu.edu/wildlife-habitat-relationships">Penn State Extension</a> points out that wildlife needs one more thing to thrive – space.

It would be very easy to fill a yard with a clutter of bird houses and man-made ponds surrounded by dense thickets of trees. In the wild though, different animals require different landscapes and the same animal may rely on more than one environment for different things. A forest landscape isn’t simply a collection of old trees and shrubs or bushes that live beneath them combined with animals. Instead, a forest is a patchwork of old trees, barren areas that may have recently been burned turning slowly into meadows. Fallen trees rot and the sunny areas they leave open are filled in with an eruption of different plant life. Newer patches of forest are full of dense clumps of young trees, while older patches are more widely spaced. 

The conversion of one eco type to another and another until reaching a mature forest is called ecological succession. Instead of everything in a large forest reaching the mature stage, everything is constantly changing. It is the patchwork of different forest types that provides for an abundance of biodiversity in a healthy forest. Because of this, it’s important to space things out a bit, leave open space and see what happens to It, what grows in the bare patch of dirt will probably be better than anything you could plant. Remember, you’re trying to leave space for other things to come close, the rest is up to the animals themselves.

How to turn your backyard into a healthy habitat for animals

One of the best ways to live with wildlife is...

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



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



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">
https://youtu.be/Ug657J67iEo?si=w96YjGMsg939LD_3
</div></figure>



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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

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



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

Today’s Video of the Day from the <a href="https://www.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;

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Santiago, the capital city of Chile. The city is located in the center of the Santiago Metropolitan Region, which has a population of about eight million people.&nbsp;



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



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

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



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



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



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



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



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

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."

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.

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.”
