Universal mechanism of methane formation discovered

The formation of the greenhouse gas methane is based on a universal mechanism. Scientists at Heidelberg University and the Max Planck Institute for Terrestrial Microbiology in Marburg have made this discovery. The interdisciplinary ...

Scientists discover how mitochondria import antioxidants

Many of the processes that keep us alive also put us at risk. The energy-producing chemical reactions in our cells, for example, also produce free radicals—unstable molecules that steal electrons from other molecules. When ...

Physical forces affect bacteria's toxin resistance, study finds

A random conversation between two Cornell researchers at a child's birthday party led to a collaboration and new understanding of how bacteria resist toxins, which may lead to new tools in the fight against harmful infections.

Fine-tuning gene expression during stress recovery

Scientists have discovered non-coding RNA has a novel role to fine-tune gene expressions during stress recovery, getting closer to uncovering a 30-year-old nuclear mystery.

Measuring stress around cells

Tissues and organs in the human body are shaped through forces generated by cells, that push and pull, to "sculpt" biological structures. Thanks to a new tool developed at McGill University, scientists will now be able to ...

Initiating DNA repair

To find out what activates SIRT6, the researchers alternately applied chemical inhibitors to human skin cells to determine which proteins were essential in getting the gene to repair the broken DNA strands. They discovered ...
