Study indicates how drug efficacy can be increased by manipulating the signalling mechanism

Researchers believe they have found a way to change the action of 60 percent of currently available medications, in some cases making them many times more effective, according to an article published in the April 21 edition of the journal Science. The discovery has the potential to improve treatments for diseases including heart disease, cancer, diabetes, depression and arthritis. The study describes a new way to manipulate perhaps the most important signaling mechanism in human cells: G-protein coupled receptors (GPCRs).

DNA "dark state" findings help explain evolution of life

Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation - an idea that has challenged some of the most basic concepts of modern biochemistry.
