Influenza A viruses typically cause severe respiratory disease mainly in the very young or the elderly. The 2009 swine-origin H1N1 virus is unusual because it preferentially infects individuals under 35 years of age. We’ve previously noted that being older is a good defense against 2009 H1N1 inf...

Exposure to low levels of antibiotics increases mutations in E. coli and Staphylococcus bacteria hundreds of time more than normal, making the creation of drug-resistance strains more likely, says a paper in today's edition of the journal Molecular Cell.
This finding adds to concerns about an... Read More
You expect the hospital to be one of the cleanest places around. But it can actually be a safe haven for super germs that can get you very, very sick. These germs are so hard to treat that scientists are now looking to the sea for solutions.
Sharks are considered to be some of the most danger... Read More
Many farmers are faced with the situation of diminishing returns, even where productivity is increasing.
It is not that new technology, such as precision systems, new formulations of fertilisers and chemicals, do not continue to increase productivity, but often the problem is that productivit... Read More
As the U.S. Department of Energy (DOE) works toward developing sustainable sources of clean renewable energy, perennial grasses have emerged as major candidates for the commercial production of cellulosic biofuels from feedstocks. However, little is known about the specific biological traits of ... Read More
BACTERIA that are resistant to antibiotics are becoming disturbingly common in people. More worrying still is that the genes which confer this resistance are also showing up in bacteria found in other animals. When resistant bacteria hop between species, that can increase the rate of evolution a... Read More
Treating herpes in people who are also infected with H.I.V. does not reduce the chances that they will pass on the AIDS virus, according to a new study.
The results were a surprise, said the lead author, Dr. Connie Celum, a professor of global health at the University of Washington. For unkn... Read More
The National Pandemic Flu Service in England is to close because of the sharp decline in cases of the H1N1 swine flu virus. From Thursday anyone who needs medical help because of flu will no longer be able to access anti-viral drugs online or via a helpline. At its peak, 40,000 people a week rec... Read More
Carl Zimmer, author, professor, journalist and podcast host for MicrobeWorld's own Meet the Scientist, is interviewed by Nicola Jones for Nature on what goes in to writing a science book.
"Acclaimed essayist Carl Zimmer has eight popular-science books to his name, on topics from parasites an... Read More
It all started with a brawny, tattooed building contractor with a passion for exotic animals. He was taking biology classes at City College of San Francisco, a two-year community college, and when students started meeting informally early last year to think up a project for a coming science comp...

The first head-to-head comparison of therapeutic monoclonal antibodies produced from plants versus the same antibodies produced from mammalian cells has shown that plant-produced antibodies can fight infection equally well.
Scientists from Washington University School of Medicine in St. Louis... Read More
Vaccination programs against whooping cough may not be fully effective because the bacteria that cause the disease have evolved new strains, a new study has found.
A team of Australian scientists has shown for the first time that two of the most common strains of the Bordetella pertussis bact... Read More
Nature magazine has just launched an iPhone application. It's essentially an eBook reader for the iPhone and iPod Touch that gives all access to Nature and Nature News content as it is published for free until April 30th when presumably they will start charging. It's available in the app store n... Read More
The National Research Foundation (NRF) and two of the local universities will be pumping a total of $206 million over the next 10 years to support a new life sciences centre in Singapore. The Singapore Centre on Environmental Life Sciences Engineering (SCELSE) will focus its study on microbial b... Read More
Could an iPhone application treat acne? A Texas dermatologist seems to think so.
The AcneApp, launched by Houston-based Dr. Greg Pearson, claims to use red and blue light to fight blemishes and improve the health of one's skin.
Dr. Pearson did not immediately respond to requests for comme... Read More
Pentagon-backed researchers have come up with a novel new way to purify water: Just add bacteria.
Scientists at Sam Houston State University (SHSU) have successfully designed portable, efficient, bacteria-based water treatment units. Two of the devices are on their way to Army bases in Afghan... Read More
Researchers have teased out the molecular process that can shut down a marauding, often deadly immune response that kills thousands each year who suffer battlefield casualties, heart attacks, strokes, automobile accidents and oxygen deprivation, according to an article published in the January e...

Hundreds of people in China believe they might have a new disease with HIV-like symptoms, but doctors suggest their illness could be the result of a mental rather than a physical condition.
The Chinese authorities have been accused of covering up respiratory illnesses like Sars in the past.

Reptiles are bred in captivity primarily for their skins, but some restaurants and population groups also want them for their meat. A study shows that eating these animals can have side effects that call into question the wisdom of eating this 'delicacy.'
Parasites, bacteria and viruses, and ... Read More
When Cal Poly professor and renowned microbiologist Raul Cano sought to revive a prehistoric strain of yeast that lay dormant in a fossilized bee’s stomach for 25 to 45 million years, his intent wasn’t to create a stir in the beer world. Yet, 15 years later, that same yeast has yielded a fruity,... Read More
