Intense tracking for swine flu shot's side effects

More than 3,000 people a day have a heart attack. If you're one of them the day after your swine flu shot, will you worry the vaccine was to blame and not the more likely culprit, all those burgers and fries?

The government is starting an unprecedented system to track possible side effects as... Read More

Sequencing-Based Approach Helps Map Genetic Interactions in Bacteria

Researchers from the Howard Hughes Medical Research Institute and the Tufts University School of Medicine reported in the advance, online edition of Nature Methods this week that they have come up with a method for identifying genes needed for bacterial survival — and mapping genetic interaction...

A Better Bug for Biofuels

While most attempts to engineer biofuel-producing microbes have focused on well-known organisms such as yeasts and E. coli, scientists also hope to co-opt the unique metabolic functions of some of the microbial world's less-studied creatures. Anthony Sinskey and his team at MIT have been catalog... Read More

C. difficile hypervirulence genes identified

Five genetic regions have been identified that are unique to the most virulent strain of Clostridium difficile (C. difficile), the hospital superbug. Researchers writing in BioMed Central's open access journal Genome Biology studied the genome of the bacterium, looking for genes relating to moti... Read More

Engineers Track Bacteria's Kayak Paddle-like Motion For First Time

Yale engineers have for the first time observed and tracked E. coli bacteria moving in a liquid medium with a motion similar to that of a kayak paddle.

Their findings, which appear online September 29 in the journal Physical Review Letters, will help lead to a better understanding of how bact... Read More

Arctic bacteria may point to oil deposits

The discovery of heat-loving bacteria in cold Arctic Ocean sediments could lead to development of a tool to help explorers detect oil and gas riches under the ocean’s floor, according to a Calgary-educated scientist.

But University of Calgary graduate Casey Hubert admits the application, whil... Read More

New Way Deadly Food-borne Bacteria Is Spread

University of Central Florida Microbiology Professor Keith Ireton has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium.

Listeria monocytogenes is a bacterium that can cause pregnant women to lose their fetuses and trigger fat... Read More

New chemically-activated antigen could expedite development of HIV vaccine

Scientists working to develop a vaccine for the human immunodeficiency virus (HIV) report they have created the first antigen that induces protective antibodies capable of blocking infection of human cells by genetically-diverse strains of HIV. The new antigen differs from previously-tested vacc... Read More

Tentative drug may allow B cells to survive and Lymphoma cells to die

A drug apparently deprived non-Hodgkin of their capability to live for a long time and multiply swiftly. This was claimed by a study conducted in the department of Microbiology  Immunology at the University of Rochester Medical Center.

To function normally, the cells that make up bodily tis... Read More

Tiny Bacteria Secret to Cicada's Success

John McCutcheon remembers the song of the cicada - the loudest song in the insect world - as the sound track to countless summer hours spent playing outside his childhood home in Rockford, Ill.

So when McCutcheon, a molecular biologist at the University of Arizona, heard the zzsssstttt of cic... Read More

New discovery reveals fate of nanoparticles in human cells

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have uncovered what happens to biomimetic nanoparticles when they enter human cells. They found that the important proteins that make up the outer layer of these nanoparticles are degraded by an enzyme called... Read More

Fish Fend Off Invading Germs With An Initial Response Similar To One Found In Humans

Since the human response to infection is highly complex, research to understand how people fight infection is facilitated by studying how similar processes occur in simpler organisms. Zebrafish are becoming an important model for human disease, since they are easily handled, maintained and manip... Read More

What should we make of the HIV vaccine 'triumph'?

Almost 26 years after HIV was discovered to be the cause of AIDS, a vaccine has at last shown signs of protecting people. Results of the RV144 trial on 16,000 volunteers in Thailand show that those receiving the vaccine reduced their risk of HIV infection by about a third – the first evidence th... Read More

That Fish Smell

From an advice column in the San Diego Reader:

"Hey, Matt: Why does all seafood smell the same, even though it comes from such different kinds of animals (mollusks, arthropods, vertebrates)? Okay, so maybe it doesn’t all smell exactly the same, but similar. The only thing all those creatures ... Read More
