Within a dangerous stomach bacterium, Yale University researchers have discovered an ancient but functioning genetic remnant from a time before DNA existed, they report in the August 13 issue of the journal Science.
To the surprise of researchers, this RNA complex seems to play a critical rol... Read More
If mice are administered an antibiotic for three days and are simultaneously infected with malaria, no parasites appear in the blood and life-threatening disease is averted. In addition, the animals treated in this manner also develop robust, long-term immunity against subsequent infections.

A dog's indiscriminate taste is not always a positive trait. In fact, it often leads to gastrointestinal infections and consequent ailments such as diarrhea and vomiting that come from eating spoiled food. Others develop gastrointestinal diseases such as inflammatory bowel diseases that are not ... Read More
British researchers said Tuesday that a new bacterium resistant to most antibiotics is becoming more common in India and Pakistan and that it has been identified in 37 people in the U.K., primarily among people who have traveled to that region to receive cheaper medical care. U.S. authorities sa... Read More
Despite the current lull in H1N1 influenza activity, experts say it's likely that the Northern Hemisphere will see a new, but still mild, wave of the virus this flu season.
The virus will continue to circulate, said Dr. Scott Lillibridge, executive director of the National Center for Emergenc... Read More
Thomas C. Peebles, 89, who isolated the measles virus, setting the stage for development of the vaccine that freed the world from the deadly scourge, died July 8 at his home in Port Charlotte, Fla. The cause of death was not reported.
Dr. Peebles also led a team that showed the tetanus vaccin... Read More
Researchers at the Rensselaer Polytechnic Institute in New York have combined the very new with the very old to develop a paint that can kill even the most resistant bacteria.
Hospitals around the world spend billions of dollars a year to maintain sterile environments. Medical equipment, bedd... Read More
How XMRV, the new human retrovirus associated with prostate cancer and chronic fatigue syndrome, might be transmitted among humans is unknown. The finding that the virus can be detected in prostate cancer cells, and in prostatic secretions of men with prostate cancer suggests that it could be se... Read More
Human clinical trials have begun on a tetravalent vaccine candidate to protect against the mosquito-borne dengue virus.
The vaccine has been in development for the last decade by scientists at the National Institutes of Health’s National Institute of Allergy and Infectious Diseases. The trial... Read More

A new nationwide research initiative has been launched to define changes in the human immune system, using human and not animal studies, in response to infection or to vaccination. Six U. S.-based Human Immune Phenotyping Centers will receive a total of $100 million over five years to conduct th... Read More
Under the microscope, the bacteria start dividing normally, two cells become four and then eight and so on. But then individual cells begin "popping," like circus balloons being struck by darts.
This phenomenon, which surprised the Duke University bioengineers who captured it on video, turns ... Read More
If your building has 10 false fire alarms one morning, it is human nature to ignore it when it goes off for the 11th time.
Similarly, when aphids are raised on plants genetically engineered to emit a compound that warns surrounding aphids of a predator, they become accustomed to the chemical ... Read More
Researchers have confirmed a long-held but unproven hypothesis that mammalian cells are capable of synthesizing RNA by copying RNA molecules directly.
The team used single-molecule sequencing technology, which has detected and quantified novel small RNAs in human cells that represent entirely... Read More
The aim of this study was to explore the relationship between pharmacy size and the likelihood of obtaining antibiotics without medical prescription at a pharmacy. In 2008 in Catalonia, two actors presented three different cases in a randomised sample of pharmacies and asked pharmacists for an a... Read More
