More bad press for free radicals. Now it seems that too many of them can impair the mouse immune system, making them unable to fight off flu.
The finding could shed light on the cause of many mysterious human immunodeficiency disorders, such as severe combined immunodeficiency (SCID), says Fr... Read More
If connective tissue fibres are under tension, bacteria do not bind to them so well. However, if the fibres are severed and slackened by a cut, the bacterial adhesion molecules recognise this and attach themselves, which enables them to cause infections.
Cells in living organisms continuously... Read More
Tuberculosis kills around 1.7 million people globally each year, and the World Health Organization (WHO) estimates around a third of the human population carries the disease, which becomes active in 10 percent of affected people. The bacteria causing the disease are becoming increasingly resista... Read More

Sometimes the story behind the discovery can be just as fascinating as the finding itself. So is the case with the new life-form announced by NASA this past week.
The microbe, which gobbles arsenic for a living, actually incorporating the toxic element into the backbone of its DNA in place of... Read More
Hardly any doctors still practicing can remember life before antibiotics, when people were routinely hospitalized for common infections, and the threat of deadly Staphylococcus shadowed even the simplest surgery. But infectious-disease specialists like Brad Spellberg of UCLA’s David Geffen Schoo... Read More
A team of Texas AgriLife Research engineers has developed a way to cut by as much as half the amount of irradiation needed to kill 99.999 percent of salmonella, E. coli and other pathogens on fresh produce.
By packing produce in a Mylar bag filled with pure oxygen, Dr. Carmen Gomes, AgriLife ... Read More
Public health triumphs like this don't come along every day.

One of the puzzles of last year's H1N1 "swine flu" pandemic--which caused thousands of deaths worldwide--was that seemingly healthy middle-aged adults were hit hardest. A study has now shown that previous infection with other, seasonal, influenza strains primed patients' immune systems to harm t... Read More

This episode: Bacteria unlike any other known life form!
A salt-loving (halophilic) bacterium which can grow in medium containing arsenic instead of phosphorus has been selected from the microbial community of Mono Lake in California. Arsenic (As) is a chemical analog of phosphorus and is usually toxic because it can enter metabolic pathways in the pl... Read More
