Sales associate Janet Lininger is having customers swipe their own credit cards (she's relieved to have recently shifted from the intimate-appa... Read More
Most of us carry a mental picture of DNA in its iconic form – the famous double helix unveiled by Francis Crick and James Watson. But researchers are beginning to develop a new picture of DNA that shows the molecule’s more dynamic side, which is capable of morphing into a large number of comple... Read More
There are more microbes on Earth than there are stars in the universe. They occupy every ecological niche, from deep-sea vents to the human gut. So you'd expect them to be staggeringly diverse. But the latest studies suggest there may be far less variation than thought.

There is definitely something haunting about rendering the invisible “visible,” particularly when it comes to dissecting layers of the corporeal self. Austrian designer Sonja Bäumel goes one step further with her “(In)visible Membranes: Life on the Human Body and Its Design Applications” project... Read More
The 10 tomatoes sitting in a Tupperware tub at the Food and Drug Administration seem to be doing nothing more than rotting, slowly. But an invisible battle is raging on the surface of the fruit, with provocative implications for food safety and the war that humans have been waging against bacter... Read More
A collaborative research team from the Uniformed Services University of the Health Sciences (USU), Australian Animal Health Laboratory and National Cancer Institute, a component of the National Institutes of Health, reports a major step forward in the development of an effective therapy against ...

Amy Wallace, freelance writer and editor-at-large at Los Angeles Magazine, has published a in-depth feature in Wired exploring why many Americans shun vaccinations and place trust in the pseudoscience around topics such as autism, H1N1 and many other illnesses. While a good chunk of this article... Read More
Influenza viruses evade infection-fighting antibodies by constantly changing the shape of their major surface protein. This shape-shifting, called antigenic drift, is why influenza vaccines -- which are designed to elicit antibodies matched to each year's circulating virus strains -- must be ref... Read More
From fungi to flies, some parasitic species have figured out how to control their host's behavior to get what they need. See what happens when bugs go really bad with this slide show from Scientific American. Read More
Six months ago, swine flu emerged as a massive threat to global health. It seemed to come out of nowhere, but this timeline explains how the origins of the H1N1 pandemic go back more than a century. Read More
Autoimmune disease has devastating consequences for healthy tissue. Now, in mice, the same cells that can drive the body to destroy its own tissue have been used to fight cancerMovie Camera.
The cells are a recently discovered type of immune cell called Th17. These cells play a key role in au... Read More
There were 1.8 million to 5.7 million cases of swine flu in the country during the epidemic’s first spring wave, according to a new estimate from the Centers for Disease Control and Prevention released Thursday.
From 9,000 to 21,000 people were hospitalized as a result, and up to 800 died fr... Read More
In some African villages, nearly everyone is infected with Mansonella perstans, a parasitic worm that’s remarkably hard to kill. It’s resistant to standard anti-worm medications, but researchers have learned that an old antibiotic can vanquish the tiny beasts — in a roundabout way.
The parasi... Read More
The human body contains billions of microorganisms, and microbial cells found in the human gut are estimated to outnumber human cells by ten-to-one in healthy adults. However, little is known about the ways in which these minute life forms influence health and disease.
That is why gastroenter... Read More
An article in The Washington Post considers the possible impact the H1N1 pandemic could have on the Internet.
"As the spread of the H1N1 flu keeps more Americans away from work and school, a federal report warns that all those people logging on to the Web from home could overwhelm Internet ne... Read More
In an article appearing in the November 2009 print issue of the FASEB Journal, they show that antioxidants -- the same substances found in plant-based foods -- might hold the key in preventing the flu virus from wreaking havoc on our lungs.
"The recent outbreak of H1N1 influenza and the rapid... Read More
Supporting Los Alamos National Laboratory's role in the international Center for HIV/AIDS Vaccine Immunology (CHAVI) consortium, researchers are using the Roadrunner supercomputer to analyze vast quantities of genetic sequences from HIV infected people in the hope of zeroing in on possible vacci...

The Manchester Science Festival 2009 is hosting "The Big Microbe Knit." A day of creativity, knitting micro-organisms such as swine flu, salmonella and the common cold. Learn about the microbes we encounter in our everyday lives and some of the more uncommon ones.
But if you can't make it to ... Read More
Global pandemics and war have long shaped human history. But due to our unprecedented ability to intervene in the spread and containment of disease as well as the recovery from injury, national security must increasingly be approached from a cellular and even a molecular level. In this series of... Read More
CSIRO researchers have identified wheat and barley lines resistant to Crown Rot -- a disease that costs Australian wheat and barley farmers $79 million in lost yield every year.
Crown Rot, which is a chronic problem throughout the Australian wheat belt, is caused by the fungus Fusarium.
