How a protein stops cells from attacking their own DNA

Viruses multiply by injecting their DNA into a host cell. Once it enters the intracellular fluid, this foreign material triggers a defense mechanism known as the cGAS-STING pathway. The protein cyclic GMP-AMP Synthase (cGAS), ...

Simplest bacteria unravelled at the cellular level

Even the simplest cell appears to be far more complex than researchers had imagined. In a series of three articles in the journal Science, researchers including Vera van Noort at the European Molecular Biology Laboratory ...

A new energy source within the cells

All our cells require the small molecule, ATP, generated in the mitochondria to cover the energy required for cell metabolism, dynamics and growth. To a lower extent and particularly in cancer cells, ATP can also be generated ...

Scientists discover extraordinary regeneration of neurons

Biologists from the University of Bayreuth have discovered a uniquely rapid form of regeneration in injured neurons and their function in the central nervous system of zebrafish. They studies the Mauthner cells, which are ...

How squid and octopus get their big brains

Cephalopods—which include octopus, squid, and their cuttlefish cousins—are capable of some truly charismatic behaviors. They can quickly process information to transform shape, color, and even texture, blending in with ...

Stem cell clues uncovered

Proper tissue function and regeneration is supported by stem cells, which reside in so-called niches. New work from Carnegie's Yixian Zheng and Haiyang Chen identifies an important component for regulating stem cell niches, ...

Physicists make crystal/liquid interface visible for first time

"Imagine you're a water molecule in a glass of ice water, and you're floating right on the boundary of the ice and the water," proposes Emory University physicist Eric Weeks. "So how do you know if you're a solid or a liquid?"
