The epithelial cells that line the intestines fire bacteria-fighting “bullets” into the gut, Vanderbilt University researchers have discovered.
The findings, featured on the cover of the April 10 issue of Current Biology, represent a new mechanism for defending the body against gut microbes.

There may be a new wave of computer technology on the way thanks to scientists at the University of Leeds and Japan’s University of Agriculture and Technology: Growing your own computer.
Magnet-making bacteria may be used to create the next generation of hard drives, making them much smaller ... Read More
Radio Mycelium proposes the construction of a series of experimental situations examining a new networked imaginary, the single organism of the fungal mycelium, in relation to pathogenic, electromagnetic communications. Participants will learn how to construct simple measurement devices, and cul... Read More
American students need a dramatically new approach to improve how they learn science, says a noted group of scientists and educators led by Michigan State University professor William Schmidt.
After six years of work, the group has proposed a solution. The 8+1 Science concept calls for a rad... Read More
The finding of viral nucleic acid sequences in illegally imported wildlife products has attracted the attention of the New York Times, which published an article entitled From the jungle to J.F.K., viruses cross borders in monkey meat. Read More
Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.
The scientists and other experts said the work was a giant step toward... Read More
Squishing a stack of virus sheets generates enough electricity to power a small liquid crystal display. With increased power output, these virus films might one day use the beating of your heart to power a pacemaker, the researchers behind them say.
Piezoelectric materials build up charge whe... Read More
The acquired immunodeficiency syndrome (AIDS) pandemic is caused by the human immunodeficiency virus (HIV-1), which attacks the immune system and leaves infected individuals susceptible to opportunistic infections. AIDS and HIV-1 are thought to have a relatively short history in humans, with the... Read More
First and foremost, this and the podcast of the virology course lectures available on iTunes is a gift to the public. I am applying to medical school and I appreciate the material on a topic I did not have time to take but have had a long standing int... Read More
Ira Flatow of Science Friday will host a panel discussion on the issues surrounding a federal advisory board that has urged scientific journals not to publish the research from two labs that have developed an airborne bird flu virus (H5N1). Virologist Vincent Racaniello and Biosecurity expert D.... Read More
Medical researchers in Spain say an experimental vaccine against HIV, the virus that causes AIDS, has produced a 90 percent immune response among a small group of healthy human test subjects. The promising results pave the way for further clinical trials on HIV-infected volunteers.

Imagine a scientist gently swabs your left nostril with a Q-tip and finds that your nose contains hundreds of species of bacteria. That in itself is no surprise; each of us is home to some 100 trillion microbes. But then she makes an interesting discovery: in your nose is a previously unknown sp... Read More
Much as people can exchange information instantaneously in the digital age, bacteria associated with humans and their livestock appear to freely and rapidly exchange genetic material related to human disease and antibiotic resistance through a mechanism called horizontal gene transfer (HGT).

One of the most economically devastating diseases in the world for those who raise cows, sheep, pigs, goats, deer and other cloven-hoofed animals is foot and mouth Disease (FMD). This incredibly contagious and fast-spreading disease causes fever, blisters on the feet and mouth (hence the name), ... Read More
Scientists have identified the genetic blueprint of the giant intestinal roundworm, Ascaris suum, revealing potential targets to control a devastating parasitic disease.
The disease, known as ascariasis, affects more than one billion people in China, South East Asia, South America, and parts ... Read More
New evidence published in mBio this week provides strong evidence that United Nation’s peacekeepers brought a cholera epidemic to Haiti.
Haiti has had a terrible history of hardship, but 2010 was an annus horribilis. In January of that year, an earthquake laid flat many parts of Haiti killed... Read More
Researchers in South East Asia have identified a novel mechanism whereby the organism Burkholderia pseudomallei – the cause of melioidosis, a neglected tropical infectious disease – develops resistance to ceftazidime, the standard antibiotic treatment. The change also makes the drug-resistant ba... Read More
