Tarantula toxin is used to report on electrical activity in live cells

Researchers have developed a novel probe that reports on the electrical activity of cells using tarantula toxin, allowing for the observation of voltage-activated ion channels in live cells. This breakthrough has the potential to help scientists understand the function of specific ion channels and identify drug targets for neurological...

Mummy remains refute antiquity of ankylosing spondylitis

Researchers used CT scans to investigate royal Egyptian mummies from the 18th-20th Dynasties, ruling out signs of ankylosing spondylitis. Instead, they found evidence of diffuse idiopathic skeletal hyperostosis (DISH) in four Pharaohs, suggesting a degenerative spinal condition, not inflammatory arthritis.
