Most Escherichia coli (E.coli) strains are harmless.But some, like enterohemorrhagic E. coli (EHEC), are a hazard to human health and life. Read More
The Global Virus Network (GVN) announced today the launch of a Task Force on HTLV, Human T-Lymphotropic Virus (HTLV), the world's first known human retrovirus and only known leukemia-causing virus. Experts from 11 countries*, led by Dr. Robert Gallo, GVN co-founder and scientific director and di... Read More
Bacteria in a drop of water spontaneously form a bi-directional vortex, with bacteria near the center of the drop swimming in the opposite direction of bacteria swimming near the edge. New computer simulations, confirmed by a novel experiment, explain how that vortex comes to be.

Proteases are vital proteins that serve for order within cells. They break apart other proteins, ensuring that these are properly synthesized and decomposed. Proteases are also responsible for the pathogenic effects of many kinds of bacteria. Now chemists at the Technische Universitaet Muenchen ... Read More
How long does it take to become a microbiologist?
I'd never heard of magnetotactic bacteria before and thought perhaps you guys might find this interesting. Not sure if you've mentioned these on TWIM before,... Read More
Romance often sparks between colleagues, and scientists are no different. Nature profiles four super-couples who have combined love and the lab.
When physicists Claudia Felser and Stuart Parkin were introduced at a conference on applied magnetics, they felt an immediate attraction. But then, ... Read More
There have been several outbreaks of highly pathogenic H5N1 avian influenza viruses affecting humans over the past decade, the causes of which have been limited to direct human contact with infected birds. Recent publications suggest that a very small number of coding mutations in the viral HA g... Read More
Researchers from Germany have identified the mechanism by which Salmonella infections can reduce the incidence of asthma in mice. The research, which appears ahead of print in the journal Infection and Immunity, opens up new avenues of research that could lead to treatments.
Incidence of alle... Read More
TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host’s body.
These findings are report... Read More
A study led by St. Jude Children’s Research Hospital scientists highlights a new approach for developing a universal influenza vaccine that could protect against multiple flu strains, including deadly pandemic strains. The research appears today in the advance online edition of the scientific jo... Read More
Three years ago today, on 13 January 2011, the last case of poliomyelitis was reported in India. This achievement represents a remarkable turnaround for a country where control of the disease had for years been extremely difficult. As recently as 2009 there were 741 confirmed cases of polio caus... Read More
The emergence of community-acquired infections, such as urinary tract infections (UTI), due to strains resistant to common antibiotics are on the rise, according to Rhode Island Hospital researchers. The study is published online in the journal Antimicrobial Resistance and Infection Control.

The man arrived at the hospital with a fever and a bad cough. Relatives accompanied him through the doors, beneath the red neon sign reading "Emergency."
It looked like pneumonia, but when doctors at Community Hospital learned that the patient was a healthcare worker in Saudi Arabia, they beg... Read More

Tuberculosis (TB) represents a serious public health problem: 8.7 million cases in 2001 and over 1.4 million deaths per year. In 2006, extensively drug-resistant (XDR) tuberculosis has been confirmed in 84 countries, heralding the possibility of virtually untreatable tuberculosis. The emergence ... Read More
Later this month (May 2014) the World Health Assembly will decide whether to destroy the remaining stocks of variola virus – the agent of smallpox – or to allow continued research on the virus at WHO-approved laboratories. We are interested in your opinion on this issue. Please follow the link t... Read More

Where humans travel, bacteria will follow. If people are in space for any amount of time, bacteria are sure to thrive there so it’s good to know that there are already researchers looking at how the environment within spaceships affects bacterial populations. Work done on planktonic colonies of ... Read More
A UNSW-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thoug... Read More
Buried deep in the mud along the banks of a remote salt lake near Yosemite National Park are colonies of bacteria with an unusual property: they breathe a toxic metal to survive. Researchers from the University of Georgia discovered the bacteria on a recent field expedition to Mono Lake in Calif... Read More
