Shape-shifting molecule tricks viruses into mutating themselves to death

A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus's genetic material. The findings from the University of Chicago and the Massachusetts Institute of Technology could bolster efforts ... Read More

How a deadly fungus evades the immune system

The fungus Candida albicans, which can be fatal in up to 40% of patients with a systemic infection, is being reconsidered by a team of researchers from the University of Toronto.

Cold Spring Harbor Lab, Seeking Human Subjects, Teams Up With Hospital System

Some of the world’s finest scientists live in a former whaling village on the North Shore of Long Island, in a compound reminiscent of an army post.

In this pastoral setting, they have very self-consciously taken themselves out of the real world into a cerebral one, where they are searching f... Read More

Purging a virus from organ transplants

Human cytomegalovirus (HCMV) is an extremely common virus, which as other members of the herpes virus family causes life-long infections in humans. Most individuals are exposed to HCMV during childhood, yet symptoms can be easily fought off by a healthy immune system. However, infections can be ... Read More

ASM 2015: True Culprit of Heart Disease Finally Apprehended?

Description: The myth that high cholesterol causes heart disease has survived only because the true culprit has not yet been apprehended. In this myth buster, the suspect has been identified as a newly described “protector” foamy virus unique to humans, which goes under the aliases of HERV-K102... Read More

Scientists reveal unique mechanism of natural product with powerful antimicrobial action

A research team at the Scripps Research Institute in Florida has published a study which details the wide-range of function of the natural product borrelidin. Borrelidin is a powerful tRNA-synthetase inhibitor which has been shown to exhibit antimicrobial characteristics, including anti-bacteri... Read More

Three Roads to Cellular Compartments

In a recent post to ASM's blog Small Things Considered, Merry Youle writes a wonderful, sometimes thrilling description of the different forms of cellular compartments that have evolved over the last 4 billion years or so. From compartmentalized, lipid-bound membranes in eukaryotes to microcomp... Read More

The 'intraterrestrials': New viruses discovered in ocean depths

Deep sea microbiology is a rapidly-growing field that we know (not surprisingly) very little about. New research investigates the ecology of methane seep ecosystems and the interaction between archaea and viruses beneath the ocean floor. A newly-discovered virus seems to self-select for mutati...
