Link identified between virus recognition, destruction in bacterial immune system

An immune system that helps bacteria combat viruses is yielding unlikely results such as the ability to edit genome sequences and potentially correct mutations that cause human disease.

University of Georgia researchers Michael and Rebecca Terns were among the first to begin to study the bact... Read More

Energetic immune cells are vital for fighting disease

A good immune system relies on a key ‘energy producing’ protein in immune cells to develop immunity to vaccines and disease, an international team of scientists has found.

The protein, called HuR (human antigen R) is critical for controlling metabolism in B cells, which make antibodies that a... Read More

Modified E. coli spin fibres as tough as spider silk

Spider silk is stronger than steel and tougher than Kevlar, but efforts to spin our own have so far failed to match the real thing. Now a German research group has come up with artificial fibres that equal its toughness, which could lead to safer airbags.

His team spliced spider genes into E.... Read More

Attention, All Scientists: Do Improv

Martha Furie stormed into the room and huffily sat down in a chair.

“Well, you know, I’ve been working really hard, studying Lyme disease,” she said, her voice tinged with disdain, to the woman sitting in the next chair. “It’s been a long process. It’s hard to talk about it.”

The other wom... Read More

The Coming Crisis in Antibiotics

An interesting TED talk about antibiotic resistant bacteria.

Antibiotic drugs save lives. But we simply use them too much — and often for non-lifesaving purposes, like treating the flu and even raising cheaper chickens. The result, says researcher Ramanan Laxminarayan, is that the drugs will... Read More

Newly discovered hormone mimics the effects of exercise

Scientists have discovered a new hormone that fights the weight gain caused by a high-fat Western diet and normalizes the metabolism -- effects commonly associated with exercising. When tested in mice, the hormone blocked the negative health effects of eating a high-fat diet. Read More

Ultracold-Resistant Chemical on Titan Could Allow It to Harbor Life

Mental Health May Depend on Creatures in the Gut

The microbiome may yield a new class of psychobiotics for the treatment of anxiety, depression and other mood disorders.The ongoing exploration of the human microbiome promises to bring the link between the gut and the brain into clearer focus. Scientists are increasingly convinced that the vast... Read More

These are the smallest bacteria ever identified

The ultra-small bacteria were discovered in groundwater. The sample was taken from Rifle, Colorado. The cells take on the appearance of tightly-coiled spirals. The bacterial cells are thought to be the smallest that a cell can be and still hold sufficient material to sustain life.

The cells h... Read More
