Former Pa. Sens. Santorum, Wofford serve as state co-chairs of ONE Vote '08, bring attention to HIV/AIDS

Former Pennsylvania Sens. Rick Santorum (R) and Harris Wofford (D), who competed in a "bitter and high-profile" Senate race in the 1990s, are joining together to serve as state co-chairs of ONE Vote '08 -- which aims to bring attention to issues of extreme poverty and global disease, including HIV/AIDS, during the presidential campaign -- the Philadelphia Inquirer reports.

WHO, Stop TB Partnership, UNITAID announce new tuberculosis test that quickly diagnoses MDR-TB

The World Health Organization, Stop TB Partnership, UNITAID and the Foundation for Innovative New Diagnostics on Monday announced a joint project to distribute a new diagnostic test for multi-drug resistant tuberculosis that can produce results in two days instead of the standard two or three months, the New York Times reports. Difficulty in identifying MDR-TB has been a "major obstacle" in controlling TB because many patients die or spread the disease while waiting for test results, the Times reports.

Chemists create synthetic catalyst that folds its molecular structure into a specific shape

When chemists want to produce a lot of a substance -- such as a newly designed drug -- they often turn to catalysts, molecules that speed chemical reactions. Many jobs require highly specialized catalysts, and finding one in just the right shape to connect with certain molecules can be difficult. Natural catalysts, such as enzymes in the human body that help us digest food, get around this problem by shape-shifting to suit the task at hand.

Microchip-based device determines the genetic signature of lung tumors

Massachusetts General Hospital (MGH) investigators have shown that an MGH-developed, microchip-based device that detects and analyzes tumor cells in the bloodstream can be used to determine the genetic signature of lung tumors, allowing identification of those appropriate for targeted treatment and monitoring genetic changes that occur during therapy. A pilot study of the device called the CTC-chip will appear in the July 24 New England Journal of Medicine and is receiving early online release.
