The spread of antibiotic resistance among bacteria is a growing problem, making certain diseases increasingly difficult to treat. New strategies for attacking the bacteria are needed, yet virtually no novel-mechanism antibiotics are currently in development.
Gram-negative bacteria - such as t... Read More
Federal health officials on Wednesday linked the H1N1 flu epidemic to a sharp rise in the number of severe bacterial infections.
Anne Schuchat, a physician at the Centers for Disease Control and Prevention, said the national trend was "worrisome" but not unexpected.

Tired of the portraits, landscapes and abstract art that peppers the walls of most art museums? According to Dutch photographer Wim von Egmond, there’s one art subject that has been ignored for centuries and finally deserves its due: microscopic organisms.
A soon-to-be-implemented policy for scientists who are permitted to conduct research in national parks will give the National Park Service a share of any profits from their work.
The policy is expected to go into effect early next year following more than a decade of concern and a lawsuit ove... Read More
Tiny magnetic discs just a millionth of a metre in diameter could be used to used to kill cancer cells, according to a study published on Sunday.
Laboratory tests found the so-called "nanodiscs", around 60 billionths of a metre thick, could be used to disrupt the membranes of cancer cells, ca... Read More
Living like a pig could be good for you. Research has shown how dirty piglets obtain 'friendly' bacteria that help them to develop healthy immune systems later in life.
The results, published online in BMC Biology1, provide the first direct link between dirty living, immune health and genetic... Read More
In his 1934 travel book Beyond the Mexique Bay, Aldous Huxley compared Guatemala's Lake Atitlan to Italy's Lake Como. The Italian body of water, he wrote, "touches the limit of the permissibly picturesque." Atitlan, however, "is Como with the additional embellishment of several immense volcanoes... Read More
The CDC notes that up to 80 percent of infections may be spread by hand contact. Alcohol-based hand sanitizers work by disrupting the outer coat of viruses and bacteria. Read More
Here's another reason to drink red wine:
"Drinking red wine in moderate amount helps to rinse teeth clean of bacteria during and after meals, says a new study.
Earlier studies have linked moderate red wine intake with everything from improved longevity to diminished risk of cardiovascular ... Read More
"The practice of sterilising surgical tools and devices has helped radically improve healthcare. Researchers in the Netherlands are trying a new method, using plasma to kill bacteria inside sealed containers.
But the old mainstay is a 130-year-old device called an autoclave, which is somethin... Read More
Several cancer vaccines that are delivered via injections or intravenous lines are in development. Another approach to a vaccine, however, is to implant a small disk containing cancer-fighting substances under the skin, according to researchers from Harvard University and the Dana-Farber Cancer ...

At least 7,826 people worldwide have died from laboratory-confirmed cases of pandemic H1N1 influenza, an increase of more than 1,000 in the last week, but the actual number is probably much larger than that, the World Health Organization said today. Most countries have now stopped counting every... Read More
Forget the chicken. At vaccine-maker Sanofi Pasteur, it all starts with the egg -- millions of them each week. The mini vaccine factories will grow more than 75 million doses of H1N1 vaccine this year.
Earlier this month, the only company to make flu shots in the United States offered reporte... Read More
HIV infections remain to be of major public health importance in Europe, with evidence of increasing transmission in several European countries. A total of 25,656 diagnosed cases of HIV infection were reported for 2008 by the countries of the European Union and European Economic Area (EU/EEA) (d... Read More
Bacteria don't have easy lives. In addition to mammalian immune systems that besiege the bugs, they have natural enemies called bacteriophages, viruses that kill half the bacteria on Earth every two days.
Still, bacteria and another class of microorganisms called archaea (first discovered in ... Read More
Researchers at E.I. du Pont de Nemours & Co. and the Seattle-based Bio Architecture Lab (BAL) have secured $9 million from the Department of Energy to explore seaweed's potential as a feedstock for biobutanol, an advanced biofuel.
Their venture appears to have largely cornered the current mar... Read More

Whitehead researchers have developed a new type of genetic screen for human cells to pinpoint specific genes and proteins used by pathogens, according to their paper in Science.
In most human cell cultures genes are present in two copies: one inherited from the father and one from the mother.... Read More
