Findings advance fundamental understanding of DNA damage by UV rays

In the same week that the U.S. surgeon general issued a 101-page report about the dangers of skin cancer, researchers at Montana State University published a paper breaking new ground on how DNA - the genetic code in every cell - responds when exposed to ultraviolet (UV) light.

Unnatural DNA bases: an interview with Professor Floyd E. Romesberg, The Scripps Research Institute

The natural DNA bases that form the letters of DNA are usually referred to as G, C, A, and T. Those are only the first letters of the chemical names. They’re often called nucleotides by their scientific name and all of them have in common a phosphate part, a sugar part and a nucleobase part.

Drug for reduction of abdominal fat in HIV patients may also reduce fatty liver disease

The only drug to receive FDA approval for reduction of the abdominal fat deposits that develop in some patients receiving antiviral therapy for HIV infection may also reduce the incidence of fatty liver disease in such patients.

Researchers use anti-tank Javelin missile detector to identify malaria parasites in blood

State-of-the-art military hardware could soon fight malaria, one of the most deadly diseases on the planet. Researchers at Monash University and the University of Melbourne have used an anti-tank Javelin missile detector, more commonly used in warfare to detect the enemy, in a new test to rapidly identify malaria parasites in blood.

Researchers reveal molecular interplay between Roquin and RNA

The Roquin protein, discovered in 2005, controls T-cell activation and differentiation by regulating the expression of certain mRNAs. In doing so, it helps to guarantee immunological tolerance and prevents immune responses against the body's own structures that can lead to autoimmune disease.

New femtosecond infrared light source helps to directly visualize hydrogen-bonded molecules

Using a newly developed, ultrafast femtosecond infrared light source, chemists at the University of Chicago have been able to directly visualize the coordinated vibrations between hydrogen-bonded molecules -- the first time this sort of chemical interaction, which is found in nature everywhere at the molecular level, has been directly visualized.

2D IR spectroscopy reveals intermediate structure during amylin aggregation pathway

Amyloid diseases, such as Alzheimer's disease, type 2 diabetes, cataracts, and the spongiform encephalopathies, all share the common trait that proteins aggregate into long fibers which then form plaques.
