Carbon dioxide and iron at the origin of life

Researchers at the University of Strasbourg have discovered a striking similarity between the way carbon dioxide (CO2) reacts with metals and the way that ancient microbes use CO2 to build their biomass, providing potential ...

New compound may stop bacteria from causing sickness

A study published in the Journal of Biological Chemistry is the first to describe a signaling pathway that affects communication—a process called quorum sensing—between Streptococcus bacteria cells.

A phospholipid pathway from plants to parasites

Recent findings by researchers at Washington University in St. Louis may aid in the development of therapies to treat parasitic infections, including malaria, and may help plant scientists one day produce hardier crops. The ...

That's cool! Flash-frozen pictures reveal molecular world

A groundbreaking technique awarded the Nobel Chemistry Prize on Wednesday has allowed scientists, using unearthly cold temperatures, to produce exquisitely detailed images of the tiniest structures in cells.

Cellular 'garbage disposal' has another job

A subset of protein complexes whose role has long been thought to consist only of chemically degrading and discarding of proteins no longer needed by cells appears to also play a role in sending messages from one nerve cell ...

Small but mighty: Tiny proteins with big roles in biology (Update)

We all know how hard it is to find something small like a dropped contact lens that blends into the background. It's similarly tough for biologists to find tiny proteins against the complex background of the cell. But, increasingly, ...
