Advance in understanding actin sheds light on cell function

A tiny chemical modification on one of the most abundant and important proteins in cells, actin, has long been somewhat mysterious, its function not fully understood, but scientists from the Perelman School of Medicine at ...

Research sheds light on how silver ions kill bacteria

The antimicrobial properties of silver have been known for centuries. While it is still a mystery as to exactly how silver kills bacteria, University of Arkansas researchers have taken a step toward better understanding the ...

Cellular factor helps package flu genome

The viral genome of influenza A—the primary cause of seasonal flu epidemics—is composed of eight RNA segments that are each encapsulated by many copies of viral nucleoprotein (NP).

Mutation reduces energy waste in plants

To this end, the team identified several thousand proteins, determined their respective amounts in mutant and reference lines and combined the findings with measurements of photosynthetic performance. Their findings were ...

New coronavirus (SARS-CoV-2) mapped out

Jean and Peter Medawar wrote in 1977 that a virus is "simply a piece of bad news wrapped up in proteins." The 'bad news' in the SARS-CoV-2 case is the new coronavirus carries its mysterious genome in the form of a very long ...
