Published Researchers identify unique survival strategies adopted by fish in the world's warmest waters
(via sciencedaily.com) Original source 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 New model could help provide expectant mothers a clearer path to safe fish consumption
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Pacific cod can't rely on coastal safe havens for protection during marine heat waves
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Fuel treatments reduce future wildfire severity
(via sciencedaily.com) Original source There is a common belief that prescribed burning, thinning trees, and clearing underbrush reduce risks of the severity of future fires. But is that true? A new project analyzing 40 studies where wildfire burned into different vegetation treatments, spanning 11 western states. Researchers found overwhelming evidence that in seasonally dry mixed conifer forests in the western U.S., reducing surface and ladder fuels and tree density through thinning, coupled with prescribed burning or pile burning, could reduce future wildfire severity by more than 60% relative to untreated areas.
Published New tomato, potato family tree shows that fruit color and size evolved together
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Wild chimpanzees seek out medicinal plants to treat illness and injuries
(via sciencedaily.com) Original source Chimpanzees appear to consume plants with medicinal properties to treat their ailments, according to a new study.
Published Newly discovered dinosaur boasts big, blade-like horns
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Wooden surfaces may have natural antiviral properties
(via sciencedaily.com) Original source Viruses, including the coronavirus that causes COVID-19, can get passed from person to person via contaminated surfaces. But can some surfaces reduce the risk of this type of transmission without the help of household disinfectants? Wood has natural antiviral properties that can reduce the time viruses persist on its surface -- and some species of wood are more effective than others at reducing infectivity.
Published Interaction with insects accelerates plant evolution
(via sciencedaily.com) Original source 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.
Published Odors are encoded in rings in the brain of migratory locusts
(via sciencedaily.com) Original source Researchers describe how odors are encoded in the antennal lobe, the olfactory center in the brain of migratory locusts. Using transgenic locusts and imaging techniques, the researchers were able to show a ring-shaped representation of odors in the brain. The pattern of olfactory coding in the antennal lobe is the same at all stages of locust development. A better understanding of olfactory coding in the locust brain should help to learn more about how the behavior of these insects is controlled, especially their swarming.
Published Fishy parenting? Punishing offspring encourages cooperation
(via sciencedaily.com) Original source Scientists discovered that Neolamprologus savoryi fish use punishment to encourage offspring to cooperate in brood care, revealing advanced cognitive abilities previously thought unique to higher vertebrates. This study highlights that punishment for promoting cooperation exists beyond human societies, prompting a reevaluation of animal intelligence.
