Driving myelination by actin disassembly

(—If a metallurgist wanted to determine how a blade was made they might cut a small cross section, mount, polish, and etch it, and then look at it under a microscope. They could probably tell right away whether ...

Plant metabolic protein tailored for nighttime growth

Everyone who took high school biology learned that photosynthesis is the process by which plants, algae and select bacteria transform the Sun's energy into chemical energy during the daytime. But these photosynthetic organisms ...

The secret to safe DNA repair

Michael Hendzel knows all too well that there is little that people can do to control the stability of their genetic code. But he hopes his latest research will help impact this elusive and crucial aspect of medicine. Published ...

Why do mitochondria retain their own genome?

It sounds like science fiction to suggest that every cell in the human body is occupied by a tiny genome-equipped organelle, with which we exist in symbiosis. But in actuality, eukaryotic life is dependent on mitochondria, ...

Researchers design first artificial ribosome

Researchers at the University of Illinois at Chicago and Northwestern University have engineered a tethered ribosome that works nearly as well as the authentic cellular component, or organelle, that produces all the proteins ...
