Beijing confirmed that a 7-year-old girl has H7N9 avian influenza and Henan province reported its first two cases, opening a new front in the spread of the virus in the world’s most populous nation. Shanghai said today two people infected with the strain of bird flu died, taking the country’s de... Read More
French health officials said Friday they are investigating three suspected cases of a deadly new respiratory virus related to SARS, in people who had close contact in the hospital with France's only confirmed case.

Like humans, mice can become infected with Borrelia. However, not all mice that come into contact with these bacteria contract the dreaded Lyme disease: Animals with a particular gene variant are immune to the bacteria, as scientists from the universities of Zurich and Lund demonstrate. Wild mic... Read More
The cyanobacterium Synechocystis produces toxins that often lead to its own demise. The biologists Stefan Kopfmann and Prof. Dr. Wolfgang Hess from the University of Freiburg have determined the logic governing this mechanism. The cyanobacterium Synechocystis produces several toxins. However, mo... Read More
Researchers have more questions than answers about the latest bird flu circulating in China, including whether birds are the only reservoir for the virus.
The World Health Organization (WHO) reports that 17 people in China have died of H7N9 infection, and there is no evidence of person-to-per... Read More
The first analysis of powder samples drilled out from the inside of once water-soaked rock shows Mars was a suitable place for microbial life to evolve, scientists with NASA’s Mars rover Curiosity mission said Tuesday.
Among the chemicals discovered inside the rock, called “John Klein,” were ... Read More
A new study of Greek patients shows that overgrowth of bacteria in the gut is definitively linked to irritable bowel syndrome (IBS). It is the first to use the "gold standard" method of examining gut bacterial cultures to connect bacteria to the cause of a disease that affects some 30 million Am... Read More
One of the most critical biological advances in the past decade was the discovery that the introduction of four simple genetic factors can turn a fully mature adult cell back into an embryonic-like state, a process called reprogramming.

Those who take part in clinical trials often have to do nasty things, from taking new drugs to forgoing sleep. Participants in a trial organised by Stanley Hazen of the Cleveland Clinic, in Ohio, had a decidedly easier task: eating steak. After reading Dr Hazen’s conclusions, though, they may be... Read More
China said it was mobilizing resources nationwide to combat a new strain of deadly bird flu that has killed four people, as Japan and Hong Kong stepped up vigilance against the virus and Vietnam banned imports of Chinese poultry.
The H7N9 bird flu strain does not appear to be transmitted fro... Read More
The World Health Organization says it appears likely that the novel coronavirus (NCoV) can be passed between people in close contact. This comes after the French health ministry confirmed a second man had contracted the virus in a possible case of human-to-human transmission. Two more people in ... Read More
Reconfiguring the genetics of the food pathogen E. coli produces hydrocarbons indistinguishable from those burned in trucks. Welding bits and pieces from various microbes and the camphor tree into the genetic code of Escherichia coli has allowed scientists to convince the stomach bug to produce... Read More
The recent news about a baby in Mississippi and 14 French adults said to have been "cured" of HIV infection has fueled excitement that the end of HIV/AIDS could be within sight. Both situations raise more questions than they currently answer.
Although no one can say we now have "the" cure for... Read More
Health officials reported four more cases of a dangerous new virus in Saudi Arabia on Tuesday.
Three of the patients diagnosed as having the novel coronavirus, or nCoV, are still being treated, a statement on the Saudi Health Ministry website said. The fourth has been discharged from a hospit... Read More
Bacteria that grows only on rocks in the Swiss Alps has helped researchers identify how alcohol might affect key brain proteins.
“Now that we’ve identified this key brain protein and understand its structure, it’s possible to imagine developing a drug that could block the binding site,” says ... Read More
LOS ALAMOS, N. M., March 29, 2013—A new study by Los Alamos National Laboratory and University of Pennsylvania scientists defines previously unknown properties of transmitted HIV-1, the virus that causes AIDS. The viruses that successfully pass from a chronically infected person to a new individ... Read More
Deep in the bowels of our, well, bowels, lurk trillions of microscopic bacteria. But don't be fooled by the big bad "B" word, intractably tied to infections and disease. In fact, these bitty bugs do us a world of good.
"There's a certain 'ick' factor associated with gut bacteria," said Lita P... Read More
The in vivo interaction between a Pseudomonas aeruginosa biofilm, on a silicone implant, and the responding polymorphonuclear leukocytes.
Image: SEM imaging depicts the interaction at day 1 post insertion of the implant in the peritoneal cavity of a mouse. The leukocytes (yellow) are damaged wi... Read More
Researchers from UNSW have cautioned that more work is needed to understand how micro-organisms respond to the disinfecting properties of silver nano-particles, increasingly used in consumer goods, and for medical and environmental applications.
Although nanosilver has effective antimicrobial... Read More
Plant and animal cells have two genomes—in the nucleus and the mitochondria. A new study describes how a clash between the two makes fruit flies sick. Diseases from a mutation in one genome are complicated enough, but some illnesses arise from errant interactions between the DNA in the nucleus a... Read More
