The detection of a new virus called XMRV in the blood of patients with chronic fatigue syndrome (CFS) in 2009 raised hope that a long-sought cause of the disease, whose central characteristic is extreme tiredness that lasts for at least six months, had been finally found. But that hypothesis has... 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
Farmers and ranchers will for the first time need a prescription from a veterinarian before using antibiotics in farm animals, in hopes that more judicious use of the drugs will reduce the tens of thousands of human deaths that result each year from the drugs’ overuse.
The Food and Drug Admin... Read More

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
The anti-vaccination movement continues to grow, despite the retraction and thorough discrediting of the 1998 scientific study that spurred much of its growth. The stubborn persistence of anti-vaxxers shows how difficult it is to dispel misinformation once that information is out there, even af... 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
According to the New York Times (Why Science Majors Change Their Minds), the decline in the number of science majors in the United States has come about in part because the subject matter is too difficult. If this explanation is true, then we have not properly prepared these students in grades K... Read More
Forget needles in haystacks. Try finding the tip of a needle in a virus. Scientists have long known that a group of viruses called bacteriophages have a knack for infiltrating bacteria and that some begin their attack with a protein spike. But the tip of this spike is so small that no one knew w... Read More
Beer discovered two years ago onboard a shipwreck from the mid-1800s could possibly be recreated using living bacteria discovered in the brew, Finnish researchers announced last Thursday.
According to Terhi Kinnunen of Reuters, Annika Wilhelmson from VTT Technical Research Centre of Finland s... 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
Researchers from the Translational Genomics Research Institute, the Technical University of Denmark, and elsewhere used whole-genome sequence typing to retrace the evolutionary history of a methicillin-resistant Staphylococcus aureus strain currently found in livestock back to its antibiotic-sus...

With NASA’s Curiosity Rover safely on Mars and ready to search for signs of life, back on Earth attempts are underway to engineer bacteria that could thrive on the Red Planet.
A team of undergraduates from Stanford and Brown Universities are busy applying synthetic biology to space exploratio... Read More
It isn't often these days that a whole new country comes into being. But that just happened, with the official hiving off of South Sudan from the rest of Sudan on 9 July.
Sudan always was an improbably huge result of post-colonial border invention, and the near-permanent civil war between the... Read More
Reuters columnist Peter Christian Hall believes the possibility that H5N1 could be effectively weaponized is remote and there is more harm than good in withholding data from two research papers that outline the methods to create an aerosolized strain of avian flu in ferrets.
"Amid the furor ... 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
One of my heroes, evolutionary microbiologist Lynn Margulis, died this past Thanksgiving. She was an amazing lady who was married to Carl Sagan for many years, and partnered with James Lovelock in discovering that the earth is an interconnected living global ecosystem run largely by microbes. Sh... 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

Bacteria and fungi are remarkably mobile. Now researchers at Tel Aviv University have discovered that the two organisms enjoy a mutually beneficial relationship to aid them in that movement - and their survival.
Fungal spores can attach themselves to bacteria, "hitching a ride" wherever the ... Read More
