Aging and neurodegeneration are both known to disrupt the production of functional proteins in cells—a process called "proteostasis," or protein homeostasis. Brain cells in particular fall prey to ...

A fish that lives in rain puddles has beaten its own record for the fastest known sexual maturity among vertebrates. Some other vertebrates come close, but they take shortcuts, says coauthor Martin ...

These fish turn up in many surprising locations, but this was one place scientists didn’t expect to find them. By Veronique Greenwood Killifish manage to endure a variety of environments. The wee ...

The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish’s embryos enter a state of extreme suspended animation or “diapause” for ...

Like other parts of our bodies, the immune system starts to wear out as we get older, and it can't fight infections as efficiently. Routine vaccinations, like the flu shot, also don't trigger as ...

When the ponds where one African fish lives dry up, its offspring put their lives on pause. And now researchers have a sense for how the creatures do it. African turquoise killifish embryos can halt ...

Aging is the main risk factor for dementia and Parkinson's disease. As age progresses, toxic protein aggregates pile up in the brain and impair neuronal function. But why does that happen? An ...
