    How two coronavirus drugs for cats might help humans fight COVID-19

    Scientists are exploring if drugs for a disease caused by a coronavirus that infects only cats might help also people infected with the coronavirus.

    Some dog breeds may have trouble breathing because of a mutated gene

    Norwich terriers don’t have flat snouts, but can suffer the same wheezing as bulldogs. It turns out that a gene mutation tied to swelling could be to blame.

    Tweaking one gene with CRISPR switched the way a snail shell spirals

    The first gene-edited snails confirm which gene is responsible for the direction of the shell’s spiral.

    With a litter of tactics, scientists work to tame cat allergies

    New research may reduce the allergen levels of house cats or make people less reactive to our feline friends.

    Bloodthirsty bedbugs have feasted on prey for 100 million years

    Research sheds light on the evolutionary history of the bloodsucking bedbugs. The first species evolved at least as early as the Cretaceous, scientists say.

    A rare, ancient case of bone cancer has been found in a turtle ancestor

    A 240-million-year-old fossil reveals the oldest known case of bone cancer in an amniote, a group that includes mammals, birds and reptiles.

    A CRISPR gene drive for mice is one step closer to reality

    Researchers have made progress toward creating a gene drive for mice in the lab. Such genetic cut-and-paste machines have yet to be made for mammals.

    A ghost gene leaves ocean mammals vulnerable to some pesticides

    Manatees, dolphins and other warm-blooded marine animals can't break down organophosphates due to genetic mutations that occurred long ago.

    Madagascar’s predators are probably vulnerable to toxic toads

    The Asian common toad, an invasive species in Madagascar, produces a toxin in its skin that’s probably toxic to most of the island’s predators.

    Why some mammal species don’t have descended testicles, but most do

    New research studying genetic vestiges suggests that descended testicles are as ancient as the first placental mammal.
