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...

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
Scientists have shown that cells' DNA-reading machinery can skim through certain kinds of damaged DNA without skipping any letters in the genetic "text." The studies, performed in bacteria, suggest a new mechanism that can allow bacteria to develop resistance to antibiotics.
The results were ... Read More
A US decision to freeze spending on treatment for HIV in several African countries has prompted concern that some of the gains made against the AIDS epidemic since 2003 could be reversed.
President George W. Bush's Emergency Plan for AIDS Relief (PEPFAR), launched in 2003, focused largely on ... Read More

An experimental vaccine based on a germ found in soil cut tuberculosis infections among people with HIV, the first time a shot has been shown to reduce cases of the most common AIDS-related cause of death in poor nations.
The shots reduced TB infections by 39 percent in patients who received ... Read More
Vesicular stomatitis virus, or VSV, has long been a model system for studying and understanding the life cycle of negative-strand RNA viruses, which include viruses that cause influenza, measles and rabies.
More importantly, research has shown that VSV has the potential to be genetically mod... Read More
This year I started a new virology course at Columbia University. The course emphasizes the common reactions that must be completed by all viruses for successful reproduction within a host cell and survival and spread within a host population. The molecular basis of alternative reproductive cycl... Read More
People with cystic fibrosis frequently have lung infections that defy treatment. Cystic fibrosis is an inherited disease that clogs airways with thick mucous. While the life expectancy for children with cystic fibrosis has increased over the past few decades, many lives are still shortened in yo... Read More
The year 2010 is, among other things, the International Year of Biodiversity.
If you did not know that — and if you are not quite sure what biodiversity even means — you are almost certainly not alone.
In a survey conducted by Gallup in 2007, 64 percent of European Union citizens either ha... Read More
When the District 9 Pennsylvania Trappers Association Coyote Hunt came to town last weekend, it was a big deal for U.S. Forget the lure of hunting an elusive wild dog. Van Why is more interested in hunting through the animals' innards.

It is already known that blueberries are rich in antioxidants and vitamins. New research from the Lund University Faculty of Engineering in Sweden shows that blueberry fibers are important and can alleviate and protect against intestinal inflammations, such as ulcerative colitis. The protective ... Read More
Capillary-driven microfluidics could drastically change point-of-care diagnostics, thanks to IBM researchers Luc Gervais and Emmanuel Delamarche.
At IBM’s Zurich Research Laboratory, the scientists created a one-step immunoassay by combining microfluidic elements and reagents such as analyte ... Read More
