Scientists may have pinpointed a potential way to prevent the flu by identifying a protein that amps up the immune system, according to a new animal study.
The synthetic protein, called EP67, is able to trigger an immune response to the "threat" of the flu virus within a couple of hours in mi... Read More
They live on your skin, up your nose, in your gut - enough bacteria, fungi and other microbes that collected together could weigh, amazingly, a few pounds.
Now scientists have mapped just which critters normally live in or on us and where, calculating that healthy people can share their bodi... Read More
Insects have been around for almost 400 million years. That’s plenty of time for evolution to fashion countless horrific deaths for them. Case in point: some insects die because a little worm vomits glowing bacteria inside their bodies.
The worm is Heterorhabditis bacteriophora, a microscopic... 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
This past February I was interviewed by the Australian Broadcasting Company on the topic of the Fouchier and Kawaoka experiments on avian influenza virus H5N1. The video, Building the Perfect Bug, has been released by Journeyman Pictures and includes interviews with S.T. Lai, Laurie Garrett, Mic... 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 towar... Read More
In a tale worthy of Sherlock Holmes, scientists in the School of Chemistry at the University of Bristol, UK have solved a biochemical mystery that had previously proven elusive for 70 years: How the fungus Talaromyces stipitatus produces stipitatic acid (6), which is a tropolone, one of an atypi...

One hundred million years ago the earth’s climate was much warmer than today and vast inland seas stretched across entire continents. The land was dominated by charismatic megafauna that would one day serve as inspiration for Sir Arthur Conan Doyle’s novel The Lost World. This period is commonly... Read More
As the world’s athletes limber up for the forthcoming Olympic games in London, infectious-disease experts are preparing for their own trials. Their competition is with the diseases that millions of athletes, officials, media and spectators bring with them as they converge from across the globe o... 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
We are surrounded by bacteria, viruses, fungi and parasites. The fact that we nevertheless do not fall prey to infections is thanks to certain cellular sensor molecules such as toll-like receptors (TLR), which recognize the molecular structure of pathogens and intercede by ensuring an often comp...

Better resistance to parasites and a less fussy diet are allowing aggressive signal crayfish from the US to threaten white-clawed crayfish native to Yorkshire.
The Yorkshire crayfish suffers from two parasites: plague, which is carried by the American invader, and porcelain disease that makes... Read More
Enterococci had been generally regarded as benign commensals, a part of our healthy intestinal microbiota. They were even invited in, being used as probiotics. But then, in the late 1970s, the first multiple drug-resistant strains appeared, and vancomycin-resistant strains followed in 1981. In r... Read More
An investigation led by UCSF has found that the risk of female-to-male HIV transmission is increased three fold for women with bacterial vaginosis, a common disorder in which the normal balance of bacteria in the vagina is disrupted.
The new research assessed the association between bacterial... Read More
The second of two papers on avian influenza H5N1 virus that caused such a furor in the past year was published today in the journal Science. I have carefully read the paper by Fouchier and colleagues, and I assure you that it does not enable the production of a deadly biological weapon. The resu... Read More
A North Carolina State University study shows that, for the first time since testing began several years ago, feral pigs in North Carolina have tested positive for Brucella suis, an important and harmful bacteria that can be transmitted to people.
The bacteria are transmitted to humans by uns... Read More
It may not be the latest style in bovine bling, but researchers at Princeton University say a golden tattoo attached to a cow’s tooth could one day tell you something about your health.
The remote sensing device has the ability to detect a single bacterium, and to demonstrate, scientists at P... Read More
In a French meadow, a creature that specialises in corrupting the bodies of other animals is getting a taste of its own medicine.
Leptopilina boulardi is a wasp that lays its eggs in fly maggots. When the wasp grub hatches, it devours its host form the inside out, eventually bursting out of its... Read More

Advances in the 1950s and 1960s, including unprecedented cooperation between Soviet and U.S. scientists, allowed polio to be eradicated throughout the Americas by 1994 and all of Europe in 1998. Eliminating the crippling scourge has been more difficult, however, in some parts of Africa and Asia.... Read More
