Scientists on the Norwich Research Park have sequenced the genome of a novel strain of Clostridium botulinum, one of the most dangerous pathogens known to man. The strain produces an unusual botulinum neurotoxin, known as type A5 neurotoxin, which was isolated by the Health Protection Agency (HP... Read More
A new microscope invented by scientists at Howard Hughes Medical Institute’s Janelia Farm Research Campus will let researchers use an exquisitely thin sheet of light -- similar to that used in supermarket bar-code scanners -- to peer inside single living cells, revealing the three-dimensional sh...

A fungus that already has a good reputation is making a name for itself as a therapeutic agent for human and plant health.
Because they are mycoparasites, Trichoderma virens are able to attack other, less desirable fungi that can harm roots and foliage of plants. Read More
There is a pressing need for antiviral agents that are effective against multiple classes of viruses. Broad specificity might be achieved by targeting phospholipids that are widely expressed on infected host cells or viral envelopes. We reasoned that events occurring during virus replication (fo...

Researchers at the Institute for Genome Sciences at UMSOM and their collaborators at the FBI, the U.S. Army Medical Research Institute of Infectious Diseases and Northern Arizona University have published the first scientific paper based on their investigation into the anthrax attacks of 2001. T... Read More
NASA and its top scientists are distancing themselves from a space agency researcher who concludes that he found alien bacterial life in meteorites that were collected many decades ago.
Richard Hoover of NASA's Marshall Space Flight Center in Huntsville, Ala., claims that he found fossils tha... Read More
This episode: Virus + bacterial enzyme = cancer killer!
The risk of being infected with antibiotic-resistant bacteria when using community gyms may not be as high as believed, a new study suggests.
Growing concerns about the spread of infection have prompted many gyms to begin extensive cleaning programs, but this finding suggests such efforts may... Read More
When Jake Harvey visits the clinical center at the National Institutes of Health in Bethesda, Maryland, he is usually dirty, itchy and wheezing—not the happiest state of affairs for a 14-year-old boy. But his doctors require that for 24 hours prior to each visit, he refrain from bathing, or usin... Read More
While the causes of type 1 diabetes aren't known for certain, a new analysis backs the possibility that cold-like viruses might trigger the disease.
Australian researchers looked at a number of studies, and concluded there is a strong association between enteroviruses and the development of t... Read More
In the war against infections, some clever bacteria, such as carbapenem-resistant Klebsiella pneumoniae, are mutating into super bugs and gaining the upper hand by becoming resistant to antibiotics, especially in New York and New Jersey, reports the U.S. Centers for Disease Control and Preventio...

Scientists still haven’t discovered a cure for the common cold, but researchers now say zinc may be the next best thing.
A sweeping new review of the medical research on zinc shows that sniffing, sneezing, coughing and stuffy-headed cold sufferers finally have a better option than just tissue... Read More
Sea-ice algae -- the important first rung of the food web each spring in places like the Arctic Ocean -- can engineer ice to its advantage, according to the first published findings about this ability.
The same gel-like mucus secreted by sea-ice algae as a kind of antifreeze against temperatu... Read More
Researchers at the University of Helsinki have specified the mechanism with which the immune defence of people can immediately identify a microbe entering the body, and launch an attack against it. The researchers also discovered how a rare, serious disease takes shape.
When a microbe enters ... Read More
Certain packaged and bulk containers of in-shell hazelnuts and mixed nuts made by DeFranco & Sons of Los Angeles have been recalled because they could contain E. coli bacteria.
Seven cases of E. coli infection, possibly linked to the nuts, have been reported in Michigan, Minnesota and Wiscons... Read More
According to the most recent report from the Centers for Disease Control and Prevention, at least 45 states have reported widespread flu activity and experts believe it may not yet be on the downswing.
While the CDC experts say there is no particular strain of flu that has taken over, they ... Read More
Dear TWiV Captain and Officers,
I am a Swedish listener in my fifties, with a neolithic MSc in computer science and nowadays active within software quality (and yes, that's an oxymoron...). I found TWiV in September 2010 and I hav... Read More
The mining industry requires significant amounts of water, and the water used becomes polluted with toxins including arsenic, mercury and sulfates. Typically, the water is cleaned with microbes which do their job by adding or removing electrons from the soup, but they need to be supplemented wit... Read More
Some of the most dreaded diseases in the world such as plague, typhoid and cholera are caused by bacteria that have one thing in common: they possess an infection apparatus which is a nearly unbeatable weapon. When attacking a cell of the body, they develop numerous hollow-needle-shaped structur... Read More
