SARS-CoV-2, the virus responsible for COVID-19, is widespread among wildlife species, according to new research. The virus was detected in six common backyard species, and antibodies indicating prior exposure to the virus were found in five species, with rates of exposure ranging from 40 to 60 percent depending on the species. SARS-CoV-2, the virus responsible

For people moving through the Bronx at different times, exposure to particulate matter 2.5 microns or bigger rises by about 2.4 percent when daily travel patterns are taken into account, according to a new study. There are significant differences in how much people are exposed to air pollution, according to a new study co-authored by

Hair follicle infections are often difficult to treat because bacteria settle in the gap between hair and skin, where it is difficult for active substances to reach them. In order to investigate this scenario more closely in the laboratory, researchers have now developed a model with human hair follicles embedded in a matrix produced using

Humanity must rethink migration as the climate crisis drives rapid global changes, researchers say. Humanity must rethink migration as the climate crisis drives rapid global changes, researchers say. With significant migration expected -- and border policies hardening -- the researchers say the "time is ripe to highlight the benefits of collaboration between nations and regions."

An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming. An international team of researchers has

A study looks at the maximum possible sizes of dinosaurs, using the carnivore, Tyrannosaurus rex, as an example. Using computer modelling, experts produced estimates that T. Rex might have been 70% heavier than what the fossil evidence suggests. A new study published today in the scientific journal Ecology and Evoiution looks at the maximum possible

When people are having a conversation, they rapidly take turns speaking and sometimes even interrupt. Now, researchers who have collected the largest ever dataset of chimpanzee 'conversations' have found that they communicate back and forth using gestures following the same rapid-fire pattern. When people are having a conversation, they rapidly take turns speaking and sometimes

Researchers have discovered that a single-celled organism, a close relative of animals, harbors the remnants of ancient giant viruses woven into its own genetic code. This finding sheds light on how complex organisms may have acquired some of their genes and highlights the dynamic interplay between viruses and their hosts. A new study published in

One of the most important controversies about human evolution and expansion is when and by what route the first hominids arrived in Europe from the African continent. Now, geological dating techniques at the Orce sites (Baza basin, Granada, Spain) place the human remains found in this area as the oldest in Europe, at approximately 1.3

Researchers have made the first scientific confirmation in Puget Sound of two distinct shark species, one of them critically endangered. Oregon State University researchers have made the first scientific confirmation in Puget Sound of two distinct shark species, one of them critically endangered. The presence of the broadnose sevengill shark and endangered soupfin shark in

Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live. While human activity has had a massive effect on the natural world, a new study from North Carolina State University finds

Lampreys are one of only two living jawless vertebrates Jaws are formed by a key stem cell population called the neural crest New research reveals the gene regulatory changes that may explain morphological differences between jawed and jawless vertebrates. One of just two vertebrates without a jaw, sea lampreys that are wreaking havoc in Midwestern
