Published In medieval England, leprosy spread between red squirrels and people, genome evidence shows
(via sciencedaily.com) Original source Evidence from archaeological sites in the medieval English city of Winchester shows that English red squirrels once served as an important host for Mycobacterium leprae strains that caused leprosy in people, researchers report.
Published New Nevada experiments will improve monitoring of nuclear explosions
(via sciencedaily.com) Original source On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear explosions around the world.
Published Wild orangutan treats wound with pain-relieving plant
(via sciencedaily.com) Original source A wild orangutan was observed applying a plant with known medicinal properties to a wound, a first for a wild animal.
Published Artificial intelligence enhances monitoring of threatened marbled murrelet
(via sciencedaily.com) Original source Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species.
Published Feathers, cognition and global consumerism in colonial Amazonia
(via sciencedaily.com) Original source Amazonia is the home of the largest variety of birds in the world. In such a unique environment, craft cultures have flourished by translating the beauty and creativity of environmental materials like feathers into stunning pieces of art. A new article examines artisanal featherwork within the context of early modern colonialism and globalization.
Published Missing link in species conservation: Pharmacists, chemists could turn tide on plant, animal extinction
(via sciencedaily.com) Original source As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.
Published Researchers parse oddity of distantly related bats in Solomon Islands that appear identical
(via sciencedaily.com) Original source A study of body size in leaf-nosed bats of the Solomon Islands has revealed surprising genetic diversity among nearly indistinguishable species on different islands.
Published Trotting robots reveal emergence of animal gait transitions
(via sciencedaily.com) Original source A four-legged robot trained with machine learning has learned to avoid falls by spontaneously switching between walking, trotting, and pronking -- a milestone for roboticists as well as biologists interested in animal locomotion.
Published Fading lights: Multiple threats to North America's firefly populations
(via sciencedaily.com) Original source Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.
Published Long snouts protect foxes when diving headfirst in snow
(via sciencedaily.com) Original source When hunting for mice in winter, red and arctic fox are known to plunge headfirst at speeds of 2-4 meters per second, but their sharp noses reduce the impact force in snow and protect them from injury, according to a new study.
Published Atomic nucleus excited with laser: a breakthrough after decades
(via sciencedaily.com) Original source For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new field of research with many technological applications. Now, nuclei can be used for extremely precise measurements. For example, a nuclear clock could be built that could measure time more precisely than the best atomic clocks available today.
Published Fixin' to be flexitarian: Scrap fish and invasive species can liven up vegetables
(via sciencedaily.com) Original source Greening the way we eat needn't mean going vegetarian. A healthy, more realistic solution is to adopt a flexitarian diet where seafoods add umami to 'boring' vegetables. A gastrophysicist puts mathematical equations to work in calculating the umami potential of everything from seaweed and shrimp paste to mussels and mackerel.
Published Test reveals mice think like babies
(via sciencedaily.com) Original source Are mice clever enough to be strategic? A neuroscientist who studies learning in humans and animals, and who has long worked with mice, wondered why rodents often performed poorly in tests when they knew how to perform well. With a simple experiment, and by acting as 'a little bit of a mouse psychologist,' he and his team figured it out.
Published Florida dolphin found with highly pathogenic avian flu
(via sciencedaily.com) Original source Report details first-ever finding of highly pathogenic avian influenza virus in North American dolphin.
Published Could fishponds help with Hawaii's food sustainability?
(via sciencedaily.com) Original source Indigenous aquaculture systems in Hawaii, known as loko i'a or fishponds, can increase the amount of fish and fisheries harvested both inside and outside of the pond. Today, aquaculture supplies less than 1% of Hawaii's 70 million pounds of locally available seafood, but revitalization of loko i'a has the potential to significantly increase locally available seafood.
Published Researchers advance detection of gravitational waves to study collisions of neutron stars and black holes
(via sciencedaily.com) Original source Researchers co-led a study that will improve the detection of gravitational waves--ripples in space and time.
Published Curiosity promotes biodiversity
(via sciencedaily.com) Original source Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers. This trait influences the cichlids' ability to adapt to new habitats.
Published Herring arrives earlier in the Wadden Sea due to climate change
(via sciencedaily.com) Original source Due to the changing climate, young herring arrive in the Wadden Sea earlier and earlier in spring.
Published Scientists replace fishmeal in aquaculture with microbial protein derived from soybean processing wastewater
(via sciencedaily.com) Original source Scientists have successfully replaced half of the fishmeal protein in the diets of farmed Asian seabass with a 'single cell protein' cultivated from microbes in soybean processing wastewater, paving the way for more sustainable fish farming practices.
Published How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon
(via sciencedaily.com) Original source How do birds fly in a coordinated and seemingly effortless fashion? Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.
