Key polarity protein uncovered

Northwestern Medicine scientists have identified a protein called CLAMP as crucial to a mechanism that organizes cells and allows some to perform specialized functions, according to a study published in the Journal of Cell ...

Potential new way to limit antibiotic resistance spreading

One of the biggest current threats to global health is the rise of multi-drug resistant bacteria, caused by the spread of antibiotic resistance amongst them. In an attempt to fight this threat, EMBL researchers have unraveled ...

How cells protect themselves against mechanical stress

The Piezo1 and Piezo2 ion channels are known to open up response to the slightest mechanical stimulus. MDC researchers have now discovered that the channels are also sensitive to changes in membrane voltage. The voltage sensitivity ...

Cells stressed out? Make mitochondria longer

Scientists at The Scripps Research Institute (TSRI) have discovered a new pathway in cells that promotes mitochondrial function during times of stress, a response that can guard against disease as we age.

Researchers identify key step in viral replication

Viruses are intracellular parasites that cause disease by infecting the cells in the body and, in a study published today in Nature Microbiology, researchers at Children's Hospital of Pittsburgh of UPMC and the University ...

Building the machinery that makes proteins

All of the proteins necessary for life are made by giant molecular machines called ribosomes. A ribosome, in turn, is built from proteins and ribosomal RNAs stitched together with immaculate precision.
