I’ve recently touched on the delicate topic of human nature. Now it's the turn of the even more inflammatory subject of race. The occasion is provided by a short commentary in Science (1), reporting on a meeting of the National Human Genome Research Institute (NHGRI). The reason that meeting was contentious is because of increasingly common research on differences in the genetic susceptibility to diseases among human populations, where “population” is often a thinly veiled synonym for race.

Every type of disease has a specific treatment program. We have drugs to treat symptoms of countless illnesses and maladies, but viral infections continue to elude treatment. While we have vaccines to prevent initial infection of some viruses and other medications to treat problematic symptoms, there is little one can do to prevent a virus from replicating and causing disease. Viral infections can be lethal and without treatment options, we are left with our own natural defenses to fight off viral invaders. This is about to change.

The Secretariat of the Joint United Nations Programme on HIV/AIDS (UNAIDS) has lost valuable ground by ignoring for years the contribution of long-term concurrent relationships to Africa's AIDS epidemic, claims says Helen Epstein, an independent consultant on public health in developing countries, ahead of World AIDS Day on British Medical Journal (www.bmj.com) today.

Sandcastle worms live in intertidal surf, building sturdy tube-shaped homes from bits of sand and shell and their own natural glue. University of Utah bioengineers have made a synthetic version of this seaworthy superglue, and hope it will be used within several years to repair shattered bones in knees, other joints and the face.

"You would glue some of the small pieces together," says Russell Stewart, associate professor of bioengineering and senior author of the study to be published online within a week in the journal Macromolecular Biosciences.

A new small satellite about the size of a loaf of bread and called Firefly is designed to help solve the mystery of the most powerful natural particle accelerator in Earth's atmosphere - TGFs, or terrestrial gamma-ray flashes - which likely result from thunderstorms.

The mission is the second project under the NSF CubeSat program. A CubeSat satellite consists of three cubes attached end to end in a rectangular shape.

A new "barcode chip" developed by researchers at the California Institute of Technology (Caltech) promises to revolutionize diagnostic medical testing. In less than 10 minutes, and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases like cancer and heart disease. 

The device, known as the Integrated Blood-Barcode Chip, or IBBC, was developed by a group of Caltech researchers led by James R. Heath, the Elizabeth W. Gilloon Professor and professor of chemistry, along with postdoctoral scholar Rong Fan and graduate student Ophir Vermesh, and by Leroy Hood, president of the Institute for Systems Biology in Seattle, Washington. 

Researchers at the Mayo Clinic studying Parkinson’s disease have made a breakthrough therapy that could slow progression of the disease or even halt its onset.

Previous research has discovered that patients with Parkinson’s have an abnormal abundance of alpha-synuclein, a protein, which is believed to be the cause of the disease. Targeting this protein has since taken forefront of their studies and researchers have developed a method to reduce the expression of alpha-synuclein in the brain.

The global economic turmoil has started having an impact on the wind energy industry in Europe. Some companies are cutting down forecasts and production for 2009 and the market is showing the first signs of slowdown.

The current economic situation is slowly affecting the wind energy industry, remarks Frost Sullivan Research Analyst Gouri Nambudripad. "We are going to see a slowing down of the double-digit growth rates that were witnessed in the past few years.
