People over age 65 are at increased risk for serious side effects while undergoing latent tuberculosis therapy, a new study finds.
Latent tuberculosis occurs when TB bacteria lurk in the body without making the person sick. The host has no symptoms of TB and is not contagious. However, there ... Read More
The Deepwater Horizon oil spill in the Gulf of Mexico was, by far, the biggest environmental story of 2010. We've turned our minds and diaries to 2011, but nature doesn't abide by the Gregorian calendar. What's going on with the nearly 5 million barrels, or 207 million gallons, of oil that leake...

A study of antibodies from people infected with H1N1 swine flu adds proof that scientists are closing in on a "universal" flu shot that could neutralize many types of flu strains, including H1N1 swine flu and H5N1 bird flu, U.S. researchers said on Monday.
They said people who were infected i... Read More
The advice for conquering a cold is time-honored: Get plenty of rest and drink lots of fluids.
While it’s hard to argue against getting proper rest, some scientists suspect that loading up on liquid — that is, beyond the normal amount required in a day — may not do much good.
Theoretically... Read More
According to a new study by researchers at Yale University and the University of Tromso in Norway, the "antibiotic holiday" would have to extend over 40 years to be effective.
“Bacterial populations have evolved resistance to most antibiotics we have,” said Jeffrey Townsend, assistant profess... Read More
Despite advances made since the emergence of SARS and avian flu, China’s ability to detect new outbreaks remains “underdeveloped,” a leading Chinese health official acknowledged last week.
The comment appeared in an article in the journal Health Affairs written jointly by Dr. Zijian Feng, dir... Read More
Fever is common, but fever is complicated. It brings up science and emotion, comfort and calculation.
As a pediatrician, I know fever is a signal that the immune system is working well. And as a parent, I know there is something primal and frightening about a feverish child in the night.

A group of students at Hong Kong's Chinese University are making strides towards storing such vast amounts of information in an unexpected home: the E. coli bacterium better known as a potential source of serious food poisoning.
"This means you will be able to keep large datasets for the long... Read More
Older adults treated for an inactive tuberculosis infection may be at increased risk of suffering liver damage from the medication, a study published Monday suggests.
Canadian researchers found that among all Quebec residents treated for so-called latent tuberculosis (TB) over six years, thos... Read More
Synthetic proteins designed in the lab—using genetic sequences never before seen in nature—work much like the real thing to sustain life.
“What we have here are molecular machines that function quite well within a living organism even though they were designed from scratch and expressed from ... Read More
Proteins on the surface of a cell twist a viral protein into position, allowing the virus to start infection and cause Measles, all in a movement as graceful as a ballroom dance, say Mayo Clinic researchers.
A team led by Roberto Cattaneo, a Mayo molecular biologist, has described the crucial... Read More
The search for a universal flu vaccine has received a boost from a surprising source: the 2009 H1N1 pandemic flu strain. Using blood samples from patients infected with the 2009 H1N1 strain, researchers developed antibodies that could bind H1N1 viruses from the last decade, as well as the 1918 f... Read More
Tongue-piercers should pick their studs wisely -- even though the risk of oral infection is generally low, certain types of studs, particularly stainless steel, may collect more bacteria, researchers found.
Though none of the 85 young people in the study ever got periodontitis, bacterial load... Read More
Genetically modified microbes could perform many useful jobs, from making biofuels and drugs, to cleaning up toxic waste. But designing the complex biochemical pathways inside such microbes is a time-consuming process of trial and error.
Christopher Voigt, an associate professor at the Univer... Read More

Some additional info that I gathered on viruses on the verge of elimination (may or may not be new to you):
It appears that the next virus on the list of FAO to eradicate is PPR virus ( Read More
Malaysia has delayed a landmark field trial to release genetically modified mosquitoes designed to combat dengue fever, an official said Tuesday, following protests from environmentalists.
In the first experiment of its kind in Asia, 4,000-6,000 male Aedes aegypti mosquitoes were originally s... Read More
An experimental gel protected female monkeys from the AIDS virus in a test designed to mimic human sexual transmission, researchers said on Wednesday.
The gel uses an AIDS drug along with a zinc compound and protected all animals tested from infection with the monkey version of HIV, the resea... Read More
A team of researchers in Chile are working to come up with a vaccine against alcoholism. If successful, the patient will get a shot a month and not crave alcohol anymore.
The genetic therapy is based on aldehyde dehydrogenase, a group of enzymes that metabolize alcohol and are thus responsibl... Read More
Researchers have documented yet another health benefit for circumcision, which can protect men against the AIDS virus, saying it can protect their wives and girlfriends from a virus that causes cervical cancer.
Wives and girlfriends of circumcised men had a 28 percent lower rate of infection ... Read More
