Detailed insight into stressed cells

When cells are stressed, they initiate a complex and precisely regulated response to prevent permanent damage. One of the immediate reactions to stress signals is a reduction of protein synthesis (translation). Until now, it was difficult to measure such acute cellular changes. Researchers have now developed a method overcoming this hurdle.

Why copper is so good at killing super bugs (and regular bacteria, too)

Researchers study chickens, ostriches, penguins to learn how flight feathers evolved

If you took a careful look at the feathers on a chicken, you’d find many different forms within the same bird — even within a single feather. The diversity of feather shapes and functions expands vastly when you consider the feathers of birds ranging from ostriches to penguins to hummingbirds. Now, researchers have taken a multidisciplinary approach to understanding how all those feathers get made.
