- Vax and Pax: Taking turns to build an eye
10-14-2006 · EurekAlert!
Opposing ball clubs don't take the field at the same time, and neither do teams of proteins responsible for creating the eye. That's why researchers at the Salk Institute for Biological Studies were surprised to find the respective team captains -- Vax2, a protein that along with Vax1 builds the optic nerve cord, and Pax6, a protein that drives retinal fate -- playing on the same field.

- Researchers attach genes to minichromosomes in maize
05-14-2007 · EurekAlert!
A team of scientists at the University of Missouri-Columbia has discovered a way to create engineered minichromosomes in maize and attach genes to those minichromosomes. This discovery opens new possibilities for the development of crops that are multiply resistant to viruses, insects, fungi, bacteria and herbicides, and for the development of proteins and metabolites that can be used to treat human illnesses.

- Binghamton University researcher makes major biofilm dispersion breakthrough
10-12-2006 · EurekAlert!
A Binghamton University biologist's discovery of a molecule that induces the dispersion of biofilms will likely mean a sea change in health care, manufacturing, shipping and pharmaceutics over the coming years.David Davies has found and is in the process of synthesizing a compound that will cause biofilm colonies to disperse, thus leaving individual bacteria up to 1,000 times more susceptible to disinfectants, antibiotics and immune functions.

- Iowa State engineers hope to build better roads by using ethanol co-products
10-15-2007 · EurekAlert!
An Iowa State University research team will do lab tests to determine whether lignin, a co-product of ethanol produced from plant fiber, could be mixed with soil to improve soil strength in roadbeds. That would make for better roads in Iowa and the Midwest.

- Vaccine thwarts the tangles of Alzheimer's
08-21-2007 · EurekAlert!
A new study by NYU Medical Center researchers shows for the first time that the immune system can combat the pathological form of tau protein, a key protein implicated in Alzheimer's disease. The researchers, led by Einar Sigurdsson Ph.D., assistant professor of psychiatry and pathology at New York University School of Medicine, created a vaccine in mice that suppresses aggregates of tau. The protein accumulates into harmful tangles in the memory center of the brains of Alzheimer's patients.

- Immune system protein starves 'staph' bacteria
02-14-2008 · EurekAlert!
A multi-disciplinary team led by Vanderbilt University investigators has discovered that a protein inside certain immune system cells blocks the growth of "staph" bacteria by sopping up manganese and zinc.The findings, reported Feb. 15 in Science, support the notion that binding metals -- to starve bacteria -- is a viable therapeutic option for treating localized bacterial infections. New treatments are urgently needed to combat antibiotic-resistant forms of staph, such as MRSA.

- Physicists set 'speed limit' for future superconducting magnet
02-11-2007 · EurekAlert!
The material currently used in magnetic resonance imaging machines -- a low-temperature superconducting alloy of niobium -- has been pushed almost as far as it can go, to around 21 Tesla. Now a team led Northwestern University researchers has identified a high-temperature superconductor -- called Bi-2212 -- as a material that might be suitable for the new wires needed to one day build the most powerful superconducting magnet in the world, a 30 Tesla magnet.

- Separating the brain's 'bad' from 'good' iron
08-23-2007 · EurekAlert!
Duke University chemists are developing ways to bind up iron in the brain to combat the neurological devastation of Parkinson's and Alzheimer's diseases. The key is to weed out potentially destructive forms of iron that generate harmful free radicals while leaving benign forms of iron alone to carry out vital functions in the body.
