In June 2011 public-health officials will mark the 30th anniversary of the first AIDs diagnosis. Much hand-wringing will ensue. Why do we not yet have an effective vaccine? How do HIV cases continue to grow?
At the same time, a small but growing number of scientists will mark the anniversary ... Read More
New Jersey education officials have decided not to require high school students to pass a biology test in order to graduate - at least, not yet.
The requirement was to kick in for the Class of 2014, or current freshmen. But when almost half the students who took the pilot test this spring fai... Read More
Health experts believe a flu epidemic was averted last year because of regular hand-washing, suggesting healthcare facilities should promote hand-washing among staff and patients to prevent the spread of disease, according to a HealthDay report.
The American Society for Microbiology and the A... Read More
According to the CDC, influenza-like-illness (ILI) reports have increased nationally, and are higher than would be expected for this time of the year. Visits to doctors for ILI have increased, with Regions 2 and 4 (the Southeastern U.S.) indicating ILI activity above the baseline. Specifically, ... Read More
Fungi are a major cause of plant diseases and are responsible for large-scale harvest failure in crops like maize and other cereals all over the world. Together with scientists from the Helmholtz Zentrum in Munich, Regine Kahmann, from the Max Planck Institute for Terrestrial Microbiology in Mar... Read More
A spoonful of genetically modified starch could be a new malaria vaccine if a new strategy that seems to work in mice also performs well in humans.
At present there is no efficient vaccine against malaria, which is caused by the plasmodium parasite. Now researchers from two laboratories in Fr... Read More
Viral DNA trapped in a bacteria cell's chromosome for millions of years has shown how bacteria becomes resistant to antibiotics
A Texas A&M University researcher has discovered how nature's most primitive immune systems worked by studying bacteria's methods of resisting antibiotics over milli... Read More

Stomach illnesses peak in winter -- sometimes spread from person to person, sometimes spread via food handled by a sick person. The reason doesn’t really matter, though, when you feel horrible. And, unlike the flu, there's no vaccine you can take to prevent an infection.
Beyond campylobacter,... Read More
California health officials will try a different approach to collecting hospital infection data because a lackluster study released Thursday has significant limitations, they said.
The department tried to have hospitals report infection rates directly to the state for the first time this year... Read More
Scary headlines about swine flu can risk distorting the real threat posed by the H1N1 virus. There also seems to be a collective amnesia among many in the media about previous coverage of the virus.
The plain facts are these. So far, 39 people are known to have died with flu since October, th... Read More

As a bitter winter storm rages on the east coast, it’s hard to knock being warm-blooded. But what about the metabolic cost of maintaining a high body temperature? Well, a new study finds that we and many other mammals keep up such a torrid temp because it’s a Goldilocks situation—98.6 is just ri... Read More
Saturn’s moon Titan is wrapped in a thick, hazy atmosphere whose chemistry may mirror conditions on Earth before life emerged here some 4 billion years ago. In October Sarah Hörst reported that the resemblance is more than superficial. She simulated Titan’s haze in the lab and found it naturally... Read More
The protein components of the plaques and tangles seen in the Alzheimer's disease brain offer a clue to the origins of the disease: It turns out that they are heavily enriched in human proteins used by herpes simplex during its life cycle: Many immune system related proteins are also found in th...

On my recent trip to record TWiV #111 at Florida Gulf Coast University, I visited Rich Condit in Gainesville. There he told me a story about how the bacteriophage T7 polymerase/promoter system was developed. It’s an interesting tale that demonstrates how important scientific advances often have ... Read More
Studying how bacteria incorporate foreign DNA from invading viruses into their own regulatory processes, Thomas Wood, professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, is uncovering the secrets of one of nature's most primitive immune systems.
