How humans domesticated the bacterium behind Botox treatments
Clostridium botulinum bacteria produce a potent neurotoxin called botulinum toxin, which causes the serious illness botulism. The toxin attacks the nervous system, leaving the body unable to control its muscles and making ...
Ancient fish bones reveal how Arctic cod species survived the last ice age
The glacial Arctic Ocean was not a barren ice desert but a breeding ground for the evolution of cold adaptation in marine fish. This is the main conclusion of a new scientific publication from Stockholm University that examines ...

Giant Jurassic fossil sheds light on the evolution of a six-legged predator
Insects belong to a broader group of six-legged animals called hexapods. This group also includes other less well-known, small animals, including diplurans or two-pronged bristletails, wingless relatives of insects with two ...
More current with less calcium: Computational models help solve longstanding ion channel evolution mystery
In the early 1980s, scientists observed an anomaly. Embedded within cell membranes, they identified ion channels with extraordinarily high conductance. These so-called "BK" (Big K, or Big Potassium) channels had roughly 10 ...
