Published Rabies outbreaks in Costa Rica cattle linked to deforestation
(via sciencedaily.com) Original source Deforestation in Costa Rica raises the risk of cattle becoming infected with rabies by vampire bats, finds a new study.
Published Genes provide hope for the survival of Arabia's last big cat
(via sciencedaily.com) Original source The release of captive bred animals carefully selected for their genes can make a significant contribution to the successful recovery of the dwindling wild population and avert the prospect of extinction. Despite revealing extremely low levels of genetic diversity in the wild leopard population in Oman, the research team discovered higher levels of genetic diversity in captive leopards across the region. This important genetic resource has the potential for a major role in successful recovery of the Arabian leopard.
Published Meerkat chit-chat
(via sciencedaily.com) Original source Researchers unravel the vocal interactions of meerkat groups and show they use two different types of interactions to stay in touch.
Published Cooperative hunting requires less brainpower than previously thought
(via sciencedaily.com) Original source Through the use of artificial intelligence technology, a team of scientists has shown that advanced cognitive abilities are unnecessary for cooperative hunting. Their findings suggest that cooperative hunting, previously thought to be a complex social behavior seen primarily in mammals such as lions and chimpanzees, can also develop in species with lower levels of cognitive ability.
Published Cloudy waters causes African fish to develop bigger eyes
(via sciencedaily.com) Original source Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study.
Published Magnetic imprint on deconfined nuclear matter
(via sciencedaily.com) Original source Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the collisions. The study provides proof that the magnetic fields exist and offers a new way to measure electrical conductivity in quark-gluon plasma.
Published Otters, especially females, use tools to survive a changing world
(via sciencedaily.com) Original source Sea otters are one of the few animals that use tools to access their food, and a new study has found that individual sea otters that use tools -- most of whom are female -- are able to eat larger prey and reduce tooth damage when their preferred prey becomes depleted.
Published Bees and butterflies on the decline in western and southern North America
(via sciencedaily.com) Original source Bee and butterfly populations are in decline in major regions of North America due to ongoing environmental change, and significant gaps in pollinator research limit our ability to protect these species, according to a new study.
Published Tiger beetles fight off bat attacks with ultrasonic mimicry
(via sciencedaily.com) Original source When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by showing that tiger beetles use ultrasonic warning signals that mimic those of toxic moths.
Published Much more than a world first image of radioactive cesium atoms
(via sciencedaily.com) Original source Thirteen years after the nuclear disaster at the Fukushima Daiichi Nuclear Power Plant (FDNPP), a breakthrough in analysis has permitted a world first: direct imaging of radioactive cesium (Cs) atoms in environmental samples.
Published Parasitic worm likely playing role in decline of moose populations
(via sciencedaily.com) Original source A parasitic worm that can infest the brains of moose appears to be playing a role in the decline of the iconic animal in some regions of North America. Moose populations have been dwindling for years across the country due to many contributing factors, but new research has found the impact of Eleaophora schneideri, also known as the arterial worm, has likely been underestimated.
Published Climate change is most prominent threat to pollinators
(via sciencedaily.com) Original source A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.
Published Highly pathogenic avian flu detected in New York City wild birds
(via sciencedaily.com) Original source A small number of New York City wild birds carry highly pathogenic H5N1 avian influenza, according to a recent study.
Published Iconic baobabs: The origin and long-distance travels of upside down trees
(via sciencedaily.com) Original source The research cracks the code on the iconic baobab tree's origin story, revealing their surprising origins in Madagascar and incredible long-distance dispersals to Africa and Australia. The study unveils how baobabs developed unique pollination mechanisms -- some attracting hawkmoths, others lemurs, and even bats -- showcasing remarkable evolutionary adaptations. The research sheds light on how climate change has shaped the baobab's distribution and diversification over millions of years, offering valuable insights for understanding plant responses to future environmental shifts.
Published The case for sharing carbon storage risk
(via sciencedaily.com) Original source Even the most optimistic projections for the rapid build-out of solar, wind, and other low-carbon resources acknowledge that coal, natural gas, and other fossil fuels will dominate the world's energy mix for decades to come. If the vast greenhouse gas emissions from burning these fossil fuels continue to enter the planet's atmosphere, global warming will not be limited to sustainable levels. The capture and geologic sequestration of carbon emissions (CCS) offer a promising solution to the world's carbon conundrum.
Published Genetics provide key to fight crown-of-thorns starfish
(via sciencedaily.com) Original source Scientists are one step closer to combating coral-destroying crown-of-thorns starfish, following a study into the pest's genetics.
Published Most dangerous areas for whale shark-shipping vessel collisions revealed
(via sciencedaily.com) Original source Heavily-used shipping lanes that pass through whale shark feeding grounds pose a threat to the species, according to scientists who have revealed areas where the creatures are at the highest risk.
Published New viruses that could cause epidemics on the horizon
(via sciencedaily.com) Original source Suddenly they appear and -- like the SARS-CoV-2 coronavirus -- can trigger major epidemics: Viruses that nobody had on their radar. They are not really new, but they have changed genetically. In particular, the exchange of genetic material between different virus species can lead to the sudden emergence of threatening pathogens with significantly altered characteristics.
Published Island birds more adaptable than previously thought
(via sciencedaily.com) Original source The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.
Published New record holder for smallest dispersers of ingested seeds: Woodlice
(via sciencedaily.com) Original source Even bugs as small as woodlice can disperse seeds they eat, setting a new record for smallest animal recorded to do so. The discovery underscores the crucial yet often overlooked role that small invertebrates play in ecosystems.
