Microbiologist professor turns microbrewer

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

Cells Can Read Damaged DNA Without Missing a Beat

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

Freeze on HIV spending sparks concern in Africa

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

Global swine flu death toll falls in past week: WHO

The global death toll from swine flu has risen to 15,174, up 463 from a week ago, but the pandemic is steadily losing momentum around the world, the World Health Organization said on Friday.

"As of 31 January 2010, worldwide more than 209 countries and overseas territories or communities have... Read More

Dirt-Dwelling Bug Blocks Tuberculosis in African Vaccine Trial

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

Naegleria’s Split Morphology Disorder

A guest blog post by "Psi Wavefunction" on Small Things Considered explores the morphology of Heterolobosea, specifically Naegleria, a species of pathogenic free-living amoebae that have a taste for human brains. Read More

Researchers reveal 3-D structure of bullet-shaped virus with potential to fight cancer, HIV

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

Virology course videocasts

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

Adapting to clogged airways makes common pathogen resist powerful antibiotics

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

Failed Efforts in Protecting Biodiversity

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

Blueberries Counteract Intestinal Diseases

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

Microfluidics Stream Their Way into Medical Tests

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

Virus pulls bait and switch on vectors

A common plant virus lures aphids to infected plants by making the plants more attractive, but when the insects taste the plant, they quickly leave for tastier, healthier ones. In the process, the insects rapidly transmit the disease, according to Penn State entomologists.

"The virus improves... Read More

Scientists make stem cells pluripotent using virus-free technique

Scientists have discovered a new and easier way to transform stem cells from human fat into induced pluripotent stem cells using virus-free techniques.
