Are Americans obligated to use an unproven vaccine to help protect people in other countries from the flu pandemic?
That is the crux of a debate over adjuvants — a class of substances that somewhat mysteriously increase the potency of vaccines. Early studies suggest that adjuvants (pronounce... Read More
Vaccinating children against hepatitis B at birth can significantly reduce liver cancer in older children, a new study in Taiwan has found.
Hepatitis B vaccination at birth became standard policy in Taiwan in 1984. For the 20-year follow-up study, scientists at the National Taiwan University... Read More
If you have ever taken a stroll through an old graveyard, you may have winced at the surprising number of tombstones bearing witness to the young age of their occupants. In the past, around 1 in 3 children died before their fifth birthday. It was common for children to perish from diphtheria, me... Read More
This briefing from the CDC covers common clinician questions regarding who should receive the H1N1 vaccine, how providers can receive the vaccine and information on priority target groups. Read More
Rice University biochemists are developing a system of "evolutionary forecasting" to better understand the mechanisms of antibiotic resistance.
"Our goal is to show antibiotic makers which sets of genes a pathogen will modify to become drug-resistant," said Yousif Shamoo, the principal invest... Read More
Scientists working to develop a vaccine for the human immunodeficiency virus (HIV) report they have created the first antigen that induces protective antibodies capable of blocking infection of human cells by genetically-diverse strains of HIV. The new antigen differs from previously-tested vacc... Read More
Besides the vaccines aimed at preventing flu, new drugs are on the way to treat it once it strikes. But it is not clear whether they will arrive in time to make a difference in thwarting the H1N1 flu pandemic.
New drugs are needed, researchers say, because there are now only four approved flu... Read More

Because it prefers to dine on some of our valued crop plants, the pea aphid (Acyrthosiphon pisum) is considered a major pest—thus a Bad Guy from our perspective. Pea aphids are not without their enemies. Enemy number... Read More
The Defense Advanced Research Projects Agency (DARPA), the research arm of the U.S. Department of Defense, has awarded Duke University $19.5 million for an effort led by the Duke Institute for Genome Sciences & Policy (IGSP) to design a portable, easy-to-use diagnostic device that can reveal who...

Researchers have developed an "on/off" switch for implantable drug delivery systems that uses an external magnet to trigger the internal release of the medicine. The half-inch implant stores the drug inside a nanoengineered membrane containing magnetitie. An external magnetic field causes the me... Read More
In “A Life of Its Own," Michael Specter explores the opportunities and challenges posed by the emerging field of synthetic biology. “No scientiﬁc achievement has promised so much, and none has come with greater risks or clearer possibilities for deliberate abuse,” Specter writes. Synthetic biolo... Read More
A killer fungus may break the chemical stalemate that is hampering anti-malaria efforts.
Mosquitoes that carry malaria are becoming increasingly resistant to insecticides. In theory, spraying two different types of insecticide at once postpones resistance, as bugs that resist one type are kil... Read More
If you are studying the gut flora of infants you would save them to run samples on a microarray, which I doubt is what our colleague will be doing with his daughter's after her debut later this afternoon. The article linked above discusses a study (http://www.plosbiology.org/article/info:doi/10... Read More

MRSA, the microbe also known as the flesh eating bacterium, not only infects humans, but can also be transmitted from people to animals and then back again.
"In a study this summer in The American Journal of Infection Control, Elizabeth A. Scott and her colleagues at the Center for Hygiene a... Read More
In a finding with potentially major implications for identifying a viral cause of prostate cancer, researchers at the University of Utah and Columbia University medical schools have reported that a type of virus known to cause leukemia and sarcomas in animals has been found for the first time in...

Ten years ago, Chicago hospitals were at ground zero when the deadly MRSA bacterium, till then confined to hospitals, learned some new tricks and spilled out into the community. This year, researchers from DOE's Argonne National Laboratory and the University of Chicago are teaming up to develop... Read More
University of Central Florida Microbiology Professor Keith Ireton has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium.
