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

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.
Listeria monocytogenes is a bacterium that can cause pregnant women to lose their fetuses and trigger fat... Read More
Studies of the new swine flu vaccine show children 10 and older will need just one shot for protection against swine flu — but younger kids almost certainly will need two.
Protection kicks in for older children within eight to 10 days, just like it does for adults, the National Institutes of ... Read More

More than three million doses of swine flu vaccine will be available by the first week of October, a little earlier than had been anticipated, federal health officials announced Friday.
But nearly all those 3.4 million doses will be of the FluMist nasal spray type, which is not recommended fo... Read More
Can taking a shower be hazardous to your health? Perhaps so, according to a study published online today in the Proceedings of the National Academy of Sciences.
We’re not talking about anything as mundane as slipping and falling in a wet, soapy shower stall. Nope, this is much creepier. We’re... Read More
A study of how HIV mutates in response to immune system pressure by Emory Vaccine Center researchers shows that the virus can take several escape routes, not one preferred route.
The results are online and scheduled for publication in the September issue of the journal Public Library of Scien... Read More
WHETHER you call the current financial situation a setback, a crisis or a meltdown, it has had at least one positive effect: financiers are searching for new ways to deal with complex risk. I have a suggestion for them. Look to nature, where analogous problems have already been solved by enginee... Read More
