This Discovery of Bizarre Dying Mechanism in Worms Could Help Us Cheat Death

When it comes, it's unstoppable. An inescapable wave of cellular death no Earthly organism can deny - but it doesn't happen the same way for everybody. For the first time, scientists have observed the phenomenon of rigor mortis – the 'stiffness of death' – seizing hold of dying worms. But while human bodies plank for the last time in death's final stages, worms seem to have it around backwards. "What really surprised us at first was that rigor mortis in worms begins while they are still alive," explains molecular biologist Evgeniy Galimov from University College London. In humans, death occurs when our heart stops beating and our brain ceases to function – but our physiological processes don't have exact equivalents in the tiny bodies of the roundworm Caenorhabditis elegans , which is why the grim reaper has to go about things a little bit differently here. "We realised that death from circulatory failure, as in mammals, doesn't happen...

Gold and Titanium Restore Vision to Blind Mice

IN BRIEF A team of Chinese researchers have restored the eyesight of blind mice by replacing their deteriorated photoreceptors with nano-wires made of gold and titanium. This method partially restored their sight, and paves the way to treating various eye diseases. For years, scientists have sought to restore vision to those with poor eyesight or who suffer from eye diseases. Last year, several developments brought us closer to this goal — researchers  reversed retinal degeneration  and  created bionic eyes . The FDA even approved a  form of gene therapy  to treat patients. The latest research attempt takes a metallic approach: researchers from Fudan University and the University of Science and Technology of China tried curing blindness using gold and titanium. The team’s research,  published in the journal  Nature Communications ,  show this method can successfully restore eyesight in mice. Specifically, the scientists replaced the mice’s ...
