Warty pig is oldest animal cave art on record

The oldest-known animal drawing in the world is a 45,500-year-old depiction of a hairy, warty pig on a cave wall in Indonesia, a new study finds. The mulberry colored painting, drawn with the red mineral ochre, shows the profile of what is likely a Sulawesi warty pig (Sus celebensis), a wild stubby-legged beast with facial […]

Results of comprehensive SARS-CoV-2 animal model study published in Nature Microbiology

San Antonio, Texas (January 4, 2020) – Scientists at Texas Biomedical Research Institute (Texas Biomed) and Southwest National Primate Research Center (SNPRC) published their findings regarding a comprehensive animal model study of SARS-CoV-2 in the peer-reviewed journal Nature Microbiology. These findings were originally posted online in BioRxiv in June of 2020. The study evaluated three […]

1st wild animal in US infected with SARS-CoV-2 found in Utah

A wild mink in Utah tested positive for SARS-CoV-2, the virus that causes COVID-19, and it may be the first “free-ranging, native wild animal” with a confirmed coronavirus infection, according to the U.S. Department of Agriculture (USDA). There’s no evidence that the virus spread further than this one infected mink, but if SARS-CoV-2 begins circulating […]

Utah mink is the first wild animal to test positive for coronavirus

A wild American mink in Utah has tested positive for the coronavirus — the first wild animal found to be infected with the virus, researchers say.   The wild mink was infected with a variant of the coronavirus that was “indistinguishable” from viruses taken from nearby farmed minks, researchers with the U.S. Department of Agriculture wrote […]

World’s oldest animal fossil actually came from rotting algae

Minimal waste production is a fundamental law for animal locomotion

Is there a unifying principle underpinning animal locomotion in its rich diversity? A thermodynamic analysis performed by a Skoltech professor and his French collaborators at Université Paris Diderot, Université Paris Saclay, and the Muséum national d’Histoire Naturelle, shows why and how waste minimization prevails on efficiency or power maximization when it comes to free locomotion […]
