Researchers have more questions than answers about the latest bird flu circulating in China, including whether birds are the only reservoir for the virus.
The World Health Organization (WHO) reports that 17 people in China have died of H7N9 infection, and there is no evidence of person-to-per... Read More
Those who take part in clinical trials often have to do nasty things, from taking new drugs to forgoing sleep. Participants in a trial organised by Stanley Hazen of the Cleveland Clinic, in Ohio, had a decidedly easier task: eating steak. After reading Dr Hazen’s conclusions, though, they may be...

Amoeba eat bacteria and other human pathogens, engulfing and destroying them – or being destroyed by them, but how these single-cell organisms distinguish and respond successfully to different bacterial classes has been largely unexplained.
In a report in the journal Current Biology, research... Read More
Bacteria on a surface wander around and often organize into highly resilient communities known as biofilms. It turns out that they organize in a rich-get-richer pattern similar to the distribution of wealth in the U.S. economy, according to a new study by researchers at University of California,...

Pancreatic cancer is a dreadful disease. Even in rich countries, only about 4% of those diagnosed with it are still alive after five years. In America it is the third-most-common cause of cancer deaths among women, after lung and breast cancer; among men it is fourth, after lung, prostate and co...

Reconfiguring the genetics of the food pathogen E. coli produces hydrocarbons indistinguishable from those burned in trucks. Welding bits and pieces from various microbes and the camphor tree into the genetic code of Escherichia coli has allowed scientists to convince the stomach bug to produce...

A 65-year-old Frenchman is hospitalized after contracting France's first case of a deadly new respiratory virus related to SARS, and French health authorities said Wednesday they are trying to find anyone who might have been in contact with him to prevent it from spreading.
It's unclear how o... Read More
Of all the things that could be hazardous to your health, would you believe breathing oxygen makes the list?
Our bodies produce toxic chemicals in our cells, called oxidants, which we fight naturally and with foods that contain antioxidants like blueberries and dark chocolate. All forms of li... Read More
In the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated 1 million people.
A new study from MIT reveals that there are many strains of H3N2 circulating in birds and pigs that are genetically ... Read More Hosts: Vincent Racaniello, Amit Kapoor, Read More
Bacteria that grows only on rocks in the Swiss Alps has helped researchers identify how alcohol might affect key brain proteins.
“Now that we’ve identified this key brain protein and understand its structure, it’s possible to imagine developing a drug that could block the binding site,” says ... Read More
New research at Washington University School of Medicine in St. Louis points to a common species of bacteria as an important contributor to bacterial vaginosis, a condition linked to preterm birth and increased risk of sexually transmitted diseases.
The condition affects one in every three wo... Read More This episode: Green algae's hydrogen production is analyzed and improved! Download Episode (3.8 MB, 4.1 minutes) Read More
Virologist Hilary Koprowski died on 11 April 2013 at the age of 96. His main accomplishments are nicely summarized in the New York Times, but for a more comprehensive overview of his life, I highly recommend his biography Listen to the Music by Roger Vaughan. I did not have many opportunities to...

Can scientists rid malaria from the Third World by simply feeding algae genetically engineered with a vaccine?
That’s the question biologists at UC San Diego sought to answer after they demonstrated last May that algae can be engineered to produce a vaccine that blocks malaria transmission. I... Read More
Deep in the bowels of our, well, bowels, lurk trillions of microscopic bacteria. But don't be fooled by the big bad "B" word, intractably tied to infections and disease. In fact, these bitty bugs do us a world of good.
"There's a certain 'ick' factor associated with gut bacteria," said Lita P... Read More
French health officials said Friday they are investigating three suspected cases of a deadly new respiratory virus related to SARS, in people who had close contact in the hospital with France's only confirmed case.
Beatrice Degrugillers, a spokeswoman for the regional health agency in France'... Read More
Researchers have found a strain of bacteria that can infect mosquitoes and make them resistant to the malaria parasite. The study, in the journal Science, showed the parasite struggled to survive in infected mosquitoes. Malaria is spread between people by the insects so it is hoped that giving m...

A key building block in the Schmallenberg virus could be targeted by anti-viral drugs, according to a new study led from the University of Leeds. The disease, which causes birth defects and stillbirths in sheep, goats and cattle, was first discovered in Germany in late 2011 and has already sprea...

Researchers at NIAID have devised a method for delivering tumor cell-killing enzymes in a way that protects the enzyme until it can do its work inside the cell. In their study in mBio this week, researchers assembled microscopic protein packages that can deliver an enzyme called PEIII to the ins...
