¿Por cuánto tiempo dura la inmunidad a la viruela? Nadie sabe en realidad, así que el gobierno alemán les pidió a los expertos en estadística que hicie... Read More
Since the human response to infection is highly complex, research to understand how people fight infection is facilitated by studying how similar processes occur in simpler organisms. Zebrafish are becoming an important model for human disease, since they are easily handled, maintained and manip... Read More
Almost 26 years after HIV was discovered to be the cause of AIDS, a vaccine has at last shown signs of protecting people. Results of the RV144 trial on 16,000 volunteers in Thailand show that those receiving the vaccine reduced their risk of HIV infection by about a third – the first evidence th... Read More
From an advice column in the San Diego Reader:
"Hey, Matt: Why does all seafood smell the same, even though it comes from such different kinds of animals (mollusks, arthropods, vertebrates)? Okay, so maybe it doesn’t all smell exactly the same, but similar. The only thing all those creatures ... Read More
According to the American College Health Association, instances of swine flu have jumped, with 7,696 new cases reported in the week of September 12-18. Read the weekly report at their website. Read More
Injectable vaccines containing inactivated viruses prevent about 50% more seasonal flu in healthy adults than the intranasal vaccine containing a weakened virus, according to a new report today in the New England Journal of Medicine.*

A form of motor neuron disease that affects children has been treated in mice with injections of stem cells into the spinal cord. The treatment extended the lives of the mice beyond and kept them more mobile, giving hope that similar approaches might help people.
The treated mice were bred to... Read More
For the first time, an experimental vaccine has prevented infection with the AIDS virus, a watershed event in the deadly epidemic and a surprising result. Recent failures led many scientists to think such a vaccine might never be possible.
The vaccine cut the risk of becoming infected with HI... Read More
Concern of a bacteria contamination has pushed McNeil Consumer Healthcare (a Johnson & Johnson company) along with the U.S. Food and Drug Administration to issue a voluntary recall of several types of Children’s TYLENOL.
An electronic letter dated September 18 states:

In areas where malaria mosquitoes have become resistant to chemical pesticides, mosquito-killing fungi can be an effective tool. Fungal spores can effectively infect and kill malaria mosquitoes, even those that are resistant to pesticides. Moreover, the mosquitoes become more susceptible to the ... Read More
Doctors are not well armed in the fight against antibiotic-resitant bacteria. It is very difficult – or, in the worst case, impossible – to fight such infections. A team of researchers in Münster has now developed a unique nanotechnology material that kills antibiotic-resitant bacteria.

A short video detailing China's vaccination program for H1N1. Over 10,000 children have already been vaccinated and there are plans to prepare for vaccinating 5% of the overall population. Read More
There has been debate among Americans regarding the benefits of space-based research. That debate may well be over due to a recent announcement from the Astrogenetix Company based in Austin, Texas. A vaccine for salmonella may go to human trials as early as next year. If these trials are appr... Read More
As health care workers in the U.S. gear up for the flu season, they facea paradox: on the one hand, they will have too little vaccine against the novel influenza A (H1N1) strain to protect the entire population; on the other, some people will resist the shots that are offered to them. Sadly, bot... Read More
Bacteria commonly used to indicate health risks in recreational waters might not be so reliable after all. Pathogenic E. coli were pervasive in stream-water samples with low concentrations of fecal indicator bacteria.
This is one of the unexpected findings from recent research that may affect... Read More
