FOR IMMEDIATE RELEASE
ACS News Service Weekly PressPac: February 17, 2010
Scientists have confirmed that the healthful substances found in green tea — renowned for their powerful antioxidant and disease-fighting properties — do penetrate into tissues of the eye. Their new report, the first documenting how the lens, retina, and other eye tissues absorb these substances, raises the possibility that green tea may protect against glaucoma and other common...
Scientists in Australia are reporting the first use of ordinary cotton thread and sewing needles to literally stitch together a microfluidic analytical device — microscopic technology that can transport fluids for medical tests and other purposes in a lab-on-a-chip. The chips shrink room-sized diagnostic testing equipment down to the size of a postage stamp, and promise revolutionary...
Where does it come from? Scientists in Arizona are reporting a surprising answer to that question, which has puzzled and perplexed generations of men and women confronted with layers of dust on furniture and floors. Most of indoor dust comes from outdoors. Their report appears in the ACS’ Environmental Science & Technology, a semi-monthly journal. In the study, David Layton and Paloma...
Call them oil droplets with a brain or even “chemo-rats.” Scientists in Illinois have developed a way to make simple oil droplets “smart” enough to navigate through a complex maze almost like a trained lab rat. The finding could have a wide range of practical implications, including helping cancer drugs to reach their target and controlling the movement of futuristic nano-machines...
In an effort to sidestep the ethical dilemma involved in using human embryonic stem cells to treat diseases, scientists are developing non-controversial alternatives: In particular, they are looking for drug-like chemical compounds that can transform adult skin cells into the stem cells now obtained from human embryos. That’s the topic of a fascinating article in Chemical & Engineering News (C&EN), ACS’ weekly newsmagazine. C&EN Associate Editor Sarah Everts notes that in 2006, researchers in Japan figured out…

- Must-reads from C&EN: The mystery of why there are so few new antibiotics
Antibiotics are among the most straight-forward drugs to develop. Nevertheless, only two new classes of these lifesavers –– oxazolidineones and lipopeptides –– have reached the market since the 1970s. Only four drug companies are active in developing antibiotics today, compared to virtually all 20 years ago. To find out why, get a copy of the story from email@example.com.
