Human Papillomavirus (HPV) is a leading cause of sexually transmitted diseases, with more than 70% of sexually active people getting the virus at least once in their lifetimes.

Chemists create new pathway to potential medicines

Posted: 08 May 2015 12:31 PM PDT

A new chemical reaction that has the potential to facilitate the search for pharmaceutical drugs has been uncovered by researchers. Organic synthesis is a scientific discipline central to the drug discovery process that is focused on building new carbon-based molecules that can affect biology -- for example, targeting and destroying cancer cells. In the study, the authors describe a new chemical reaction that converts simple starting materials into architecturally complex molecules (a collection of atoms bonded to one another) called "decalins" in a single step.

Alzheimer protein's structure may explain its toxicity

Posted: 07 May 2015 12:58 PM PDT

The molecular structure of one of the proteins in the fine fibers of the brain plaques that are a hallmark of Alzheimer's disease, researchers have found. This molecule, called amyloid beta-42, is toxic to nerve cells and is believed to provoke the disease cascade.
