An at-risk species of fish has established itself in lochs across Scotland with the help of conservation managers and by rapidly adapting to its new environment, resulting in changes to their DNA, their ecology, and body shape, according to a new study.
Researchers are discovering thousands of new bacterial species that live with us, on us and even inside us. Our relationship with them affects our health and that of the planet—but to define that relationship, new species need new names.
Oviraptorosaurs are a group of birdlike dinosaurs that were part of the ancestral dinosaur lineage that later gave rise to birds. Oviraptorosaurs walked on two legs, had a powerful toothless beak and were covered in feathers.
Researchers at Karolinska Institutet have revealed a central proprioceptive organ built directly into the central nervous system that acts as an inner movement sensor. The article was recently published in the journal Neuron.
Scientists from the Genomic Integrity and Structural Biology Group led by Rafael Fernández-Leiro at the Spanish National Cancer Research Centre (CNIO) have discovered how certain proteins ensure the repair of errors introduced into the DNA during its replication. Using cryo-electron microscopy, ...
In the cold, choppy waters of Alaska's Resurrection Bay, all eyes were on the gray water, looking for one thing only. It wasn't a spout from humpback whales that power through this scenic fjord, or a sea otter lazing on its back, munching a king crab.
Looking like the Eye of Sauron from the Lord of the Rings Trilogy, an ancient undersea volcano was slowly revealed by multibeam sonar 3,100 meters below our vessel, 280 kilometers southeast of Christmas Island. This was on day 12 of our voyage of exploration to Australia's Indian Ocean Territori ...
Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated.
The 'missing link' that helped our ancestors to begin communicating with each other through language may have been iconic sounds, rather than charades-like gestures—giving rise to the unique human power to coin new words describing the world around us, a new study reveals.
In a study, published in Science Advances, an international team of researchers have identified 28 gene regions that have been particularly important in the evolution of Darwin's finches.

You walk and talk and live on land, but your ancient relatives were fish.It took about 480 million years for these fish to evolve and adapt to different environments and become the many different back-boned species (including ourselves) that are known as vertebrates.
Archaeologists have managed to get near-perfect notes out of a musical instrument that's more than 17,000 years old. It's a conch shell that was found in a hunter-gatherer cave in southern France.
Baikal, Biwa and Bosuntwi. Maracaibo, Malawi and Matano. Tule, Tahoe and Titicaca.Ancient lakes, they're called: waterbodies more than 130,000 years old. Over their long histories, they've seen countless changes—warming and cooling cycles, wet and dry periods, altered biology and chemistry.
Curtin University researchers studying one of the oldest collections of ancient animal bones in the world have used DNA still present in the bones to identify 17 animal species, including two rodents previously not known to be in the collection.
Large parts of the Sahara Desert were green thousands of years ago, evidenced by prehistoric engravings in the desert of giraffes, crocodiles and a stone-age cave painting of humans swimming.
In the fairy-tale landscape of the Isle of Skye off the north-west coast of Scotland, the skull of one of the most ancient salamanders ever discovered to date was excavated from Jurassic limestones. But it would be decades until scientists had the technology and the funding to piece the salamand ...

In their paper published in Proceedings of the Royal Society B, Xiangbo Guo, Paul Selden and Dong Rend describe where th ...
A landmark study led by the University of Aberdeen has provided the clearest ever picture of ancient weather patterns in Europe—and could improve models used to predict how climate change will affect the Continent in future.
Researchers at Curtin revealed how behavioral and ecological factors influence the quality of bee venom, a product widely known for its effective treatment of degenerative and infectious diseases such as Parkinson's and osteoarthritis.
Researchers say conservation of some of the world's most endangered species needs to take cultural knowledge of the animals into account when working out how best to protect them.
For more than ten years now, scientists have been discussing the so-called reproducibility crisis: often, scientific findings cannot be reproduced at a later time and/or in other laboratories, although the studies are carried out under highly standardized conditions.
People have been trying to understand how predators and prey are able to stay balanced within our planet's ecosystems for at least 2,400 years.
A team of scientists, led by the University of St Andrews, has shown that rapid CO2 release from the ocean around Antarctica helped end the last ice age.
Antarctica's ice sheet spans close to twice the area of the contiguous United States, and its land boundary is buttressed by massive, floating ice shelves extending hundreds of miles out over the frigid waters of the Southern Ocean. When these ice shelves collapse into the ocean, they expose tow ...
The 2021 Antarctic ozone hole reached its maximum area on October 7 and ranks 13th largest since 1979, scientists from NOAA and NASA reported today. This year's ozone hole developed similarly to last year's:
Antarctica is getting 28 new place names to recognise British individuals who've made a major contribution to advancing science in the polar regions. The list includes Jonathan Shanklin, co-discoverer of the ozone hole, and Alastair Fothergill, whose BBC films such as Frozen Planet have widened ...
When Earth's snow and ice cover melts, the reflectivity of Earth's surface—known as albedo—decreases. And when the albedo of Earth's surface decreases, a smaller share of sunlight is reflected back into space.
Ukrainian scientists got a shock when they woke up on Monday to find that the snow around their station had turned red as blood. But rather than being anything sinister, the red tint in the snow is caused by the microscopic Chlamydomonas nivalis algae.
A team of researchers from Italy, the U.K. and South Africa has found that over the past decade, the only two flowering plants in Antarctica have been growing more rapidly.
Anthropogenic, or human-made, heat flux in the near-surface atmosphere has changed urban thermal environments. Meanwhile, the number of extreme temperature events in the first decade of the 21st century grew faster than in the last 10 years of the 20th century. During this period, urban extreme ...
Since the Industrial Revolution, human activities have increased the emission of nitrogen oxides (NOx). NOx can promote the generation of ozone and particle matters, and increase nitrogen deposition in the atmosphere.
Bats have got a pretty raw deal in popular culture ever since Bram Stoker’s 1897 book 'Dracula' cemented the connection between largely unlovely ‘hand-winged’ chiroptera and the blood-sucking vampires of folklore. Not even the charisma of Batman, who made his superhero debut 42 years later, has ...
A water-absorbent coat to keep rust away? It may seem counterintuitive but when it comes to soybean plants and rust disease, researchers from Japan have discovered that applying a coating that makes leaf surfaces water absorbent helps to protect against infection.
Scientists recently announced the discovery of a novel antibiotic produced by bacteria living inside a nematode (roundworm). Although this molecule needs further analyses, the finding, published in Nature, brings hope to the fight against antimicrobial or antibiotic resistance, the growing abili ...
Fish populations around the world are at risk due to growing levels of pharmaceutical contamination in waterways, according to an international team of researchers from Monash University, the University of Western Australia (UWA), the Swedish University of Agricultural Sciences, and New York Uni ...
Great apes do not pass on their behavior to the next generation. Unlike humans, they do not copy the specific knowledge of those around them, instead learning it anew in each generation. This is shown in a study by Dr. Alba Motes-Rodrigo and Dr. Claudio Tennie of the "Tools and Culture in Early ...
When they're prepared for transport, apples and other fruits are often treated with a fungicide to prevent spoilage and extend shelf life.
Professor Nicole Boivin, Director of the Department of Archaeology at the Max Planck Institute for the Science of Human History in Jena, Germany, is part of an international initiative to examine the implications of past land use for contemporary conservation efforts.
Lurking beneath overhanging foliage, archerfish have one thing on their mind: taking a well-aimed pot-shot at the next insect that settles within range. Squirting a ballistic jet of water, these tenacious assassins precisely target their victims, ready to dine.
It's hard to imagine the Arctic without sea ice.But according to a new study by UCLA climate scientists, human-caused climate change is on track to make the Arctic Ocean functionally ice-free for part of each year starting sometime between 2044 and 2067.
Scientists with the European Space Agency (ESA) said on May 25, 2021, that satellite data have revealed how much warming Atlantic waters are intruding on Arctic sea ice. They said they made their announcement “with alarm bells ringing about the rapid demise of sea ice in the Arctic.”
China is just one of many countries in the Northern Hemisphere experiencing an extremely cold winter due in part to both the tropical Pacific and the Arctic, according to an analysis of temperatures from Dec. 1, 2020 to mid-January of 2021.
