Published Extinct humans survived on the Tibetan plateau for 160,000 years



Bone remains found in a Tibetan cave 3,280 m above sea level indicate an ancient group of humans survived here for many millennia.
Published Ocean acidification turns fish off coral reefs



A new study of coral reefs in Papua New Guinea shows ocean acidification simplifies coral structure, making crucial habitat less appealing to certain fish species.
Published Genetic patterns of world's farmed, domesticated foxes revealed via historical deep-dive



Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their nutritional needs. But the process of domestication remains a bit of a mystery.
Published Researchers identify unique survival strategies adopted by fish in the world's warmest waters



A team of researchers have identified unexpected ways coral reef fish living in the warmest waters on earth, in the Arabian Gulf, have adapted to survive extreme temperatures.
Published The evidence is mounting: humans were responsible for the extinction of large mammals



Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.
Published New model could help provide expectant mothers a clearer path to safe fish consumption



Research creates a framework to better balance the nutritional benefit of fish consumption with the risk of mercury exposure to the developing brain.
Published New mathematical model sheds light on the absence of breastfeeding in male mammals



Mathematicians ave put forward a hypothesis which suggests that the reason male mammals don't breastfeed might be driven by the rich community of microbes that lives in breast milk and which plays an important part in establishing the gut microbiome of the infant.
Published Last surviving woolly mammoths were inbred but not doomed to extinction



The last population of woolly mammoths was isolated on Wrangel Island off the coast of Siberia 10,000 years ago, when sea levels rose and cut the mountainous island off from the mainland. A new genomic analysis reveals that the isolated mammoths, who lived on the island for the subsequent 6,000 years, originated from at most 8 individuals but grew to 200--300 individuals within 20 generations. The researchers report that the Wrangel Island mammoths' genomes showed signs of inbreeding and low genetic diversity but not to the extent that it can explain their ultimate (and mysterious) extinction.
Published Pacific cod can't rely on coastal safe havens for protection during marine heat waves



During recent periods of unusually warm water in the Gulf of Alaska, young Pacific cod in near shore safe havens where they typically spend their adolescence did not experience the protective effects those areas typically provide, a new study found.
Published Bird flu stays stable on milking equipment for at least one hour



H5N1 virus in unpasteurized milk is stable on metal and rubber components of commercial milking equipment for at least one hour, increasing its potential to infect people and other animals.
Published Invasive ants spread by hitchhiking on everyday vehicles



Ants might spread to new locations by stowing away on everyday vehicles. Previously, this was thought to occur mostly on agricultural equipment.
Published Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds



We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.
Published Brain's 'escape switch' controlled by threat sensitivity dial



Neuroscientists have discovered how the brain bidirectionally controls sensitivity to threats to initiate and complete escape behaviour in mice. These findings could help unlock new directions for discovering therapies for anxiety and post-traumatic stress disorder (PTSD).
Published Frog 'saunas' a lifeline for endangered frog populations



New biologist-designed shelters will help endangered frogs survive the devastating impacts of a deadly fungal disease by regulating their body temperature to fight off infections.
Published New tomato, potato family tree shows that fruit color and size evolved together



A new family tree of the plant genus Solanum helps explain the striking diversity of their fruit color and size. This genus includes tomatoes, potatoes, eggplants, and other economically important plants.
Published Unifying behavioral analysis through animal foundation models



Behavioral analysis can provide a lot of information about the health status or motivations of a living being. A new technology makes it possible for a single deep learning model to detect animal motion across many species and environments. This 'foundational model', called SuperAnimal, can be used for animal conservation, biomedicine, and neuroscience research.
Published New study finds dinosaur fossils did not inspire the mythological griffin



For centuries, scientists thought they knew where the griffin legend came from. A new study takes a closer look at the data and folklore's influence on science.
Published Newly discovered dinosaur boasts big, blade-like horns



A new dinosaur has been identified and named. The dinosaur's name, Lokiceratops rangiformis, translates roughly to 'Loki's horned face that looks like a caribou.'
Published Insecticides contributed to loss of butterflies across American Midwest, study finds



Insecticide use is a major factor causing a decrease in the size and diversity of butterfly populations across the US Midwest, according to a new study.
Published Interaction with insects accelerates plant evolution



Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.
