    Specialized protein helps these ground squirrels resist the cold

    A less active cold-sensing protein explains, in part, why some hibernating ground squirrels are more tolerant of chilly conditions than the animals’ nonhibernating kin.

  16. Life

    A deadly fungus is infecting snake species seemingly at random

    A fungal disease doesn’t appear to discriminate among snake species, suggesting many of the reptiles may be at risk.
