Scientists have detected infection by at least three variants of the virus that causes COVID-19 in free-ranging white-tailed deer in six northeast Ohio locations, the research team has reported.
Researchers lay groundwork for potential dog-allergy vaccine
Scientists have identified a series of molecular candidates for those parts of dog allergens that cause immune reactions in people--the first step in developing a vaccine against most causes of dog allergies.
For some Greenlanders, eating sugar is healthy
A genetic variation among some Greenlanders makes sugar healthy -- significantly more than for most people. According to a new study, gut bacteria and a unique diet that has nourished Greenlanders for millennia have provided them with a genetic variation that offers an incredible advantage.
Melting of the Antarctic ice sheet could cause multi-meter rise in sea levels by the end of the millennium
Scientists predict that continued global warming under current trends could lead to an elevation of the sea level by as much as five meters by the year 3000 CE.
Team succeeds in culturing the pygmy zebra octopus
Researchers report culturing methods for the pygmy zebra octopus, an emerging laboratory research organism.
Birds’ dazzling iridescence tied to nanoscale tweak of feather structure
Researchers found that the iridescent shimmer that makes birds such as peacocks and hummingbirds so striking is rooted in an evolutionary tweak in feather nanostructure that has more than doubled the range of iridescent colors birds can display. This insight could help researchers understand how and when iridescence first evolved...
Exquisitely preserved embryo found inside fossilized dinosaur egg
A 72 to 66-million-year-old embryo found inside a fossilized dinosaur egg sheds new light on the link between the behavior of modern birds and dinosaurs, according to a new study.
Extinct reptile discovery reveals earliest origins of human teeth, study finds
A new extinct reptile species has shed light on how our earliest ancestors became top predators by modifying their teeth in response to environmental instability around 300 million years ago.
Plants as cold specialists from the ice age
Plants of the spoonweed group time-and-again quickly adapted to a changing climate during the Ice Ages of the last two million years. Evolutionary biologists and botanists used genomic analyses to study what factors favor adaptation to extreme climatic conditions. The evolutionary history of the Brassicaceae family provides insights into how...
Crows keep special tools extra safe
Just like humans, New Caledonian crows are particularly careful when handling their most valuable tools, according to a new study. The research reveals that crows are more likely to store relatively complex and efficient foraging tools for future use than more basic tools.
