University of Illinois at Urbana-Champaign researchers are developing a new solid-state nanopore sensor that they believe can move the reality of fast and affordable genome sequencing a step closer. The sensor, made by drilling a tiny hole through a thin film of aluminum oxide, could ultimately prove capable of performing DNA analysis with a single molecule. This would offer tremendous possibilities for personalized medicine and advanced diagnostics, according to the scientists, who published their paper online April 14 in Advanced Materials.

The reason deadly infections like HIV and hepatitis C never go away is because these viruses disarm the body’s defense system. However, scientists at the University of Alabama at Birmingham (UAB) recently reported (Science Online May 14) that a key immunity protein must be present for this defense system to have a chance against chronic infection.
Research up to now has tried but failed to decipher the cross-talk between killer T-cells and helper T-cells in the battle against viruses, according to the investigators. The new UAB study finds this cross-talk can only happen in the presence of ...more.

As part of GEN's ongoing celebration of the "Year of Darwin," this week's podcast takes a close look at how disease, parasites, germs, and other microbes helped shape the evolution of the human species. We think of disease as our enemy, something we try to eradicate; germs and infections are things we battle. But evolutionary biologist Dr. Marlene Zuk, in her book Riddled with Life, reveals that, in fact, disease can be our partner not our foe and is responsible for everything from how we look to how ...more.

An international research team has identified a number of unsuspected genetic variants associated with systolic blood pressure, diastolic blood pressure, and hypertension, suggesting potential avenues of investigation for the prevention or treatment of high blood pressure. The research, which was published in Nature Genetics on May 10, was funded in part by the National Heart, Lung, and Blood Institute (NHLBI) of the NIH and by several other NIH institutes and centers.
During this week's podcast Dr. Daniel Levy, first author ...more.

A number of attendees at BIO 2009 mentioned the release of a new "Global Impact Study" on agbiotech. The report was produced by PG Economics, which is based in the U.K.
"The Global Impact Study shows that agricultural biotechnology contributes to both environmental and exonomic sustainability," noted Sharon Bomer Lauristen, executive vp for food and agriculture for BIO.
"A record 13.3 million farmers in 25 countries are using agricultural ...more.
