New insights into sleep difficulties among older people

A new study of the brain's master circadian clock - known as the suprachiasmatic nucleus, or SCN - reveals that a key pattern of rhythmic neural activity begins to decline by middle age. The study, whose senior author is UCLA Chancellor Gene Block, may have implications for the large number of older people who have difficulty sleeping and adjusting to time changes.

Molecularly targeted glue for cancer

"This is a totally new approach to cancer therapy," says Professor Patrick Gunning of the Department of Chemical and Physical Sciences. "Everything prior to this has targeted functionally relevant binding sites. Our approach inhibits the mobility of cancer-promoting proteins within cells-essentially, it's like molecularly targeted glue."

Two NJIT researchers receive U.S. Patent for nanoprobe array technique

Reginald C. Farrow and Zafer Iqbal, research professors at NJIT, were awarded a patent today for an improved method of fabricating arrays of nanoscale electrical probes. Their discovery may lead to improved diagnostic tools for measuring the spatial variation of electrical activity inside biological cells.

Novel method of disguising nanoparticles as red blood cells to fight cancer

Researchers at the University of California, San Diego have developed a novel method of disguising nanoparticles as red blood cells, which will enable them to evade the body's immune system and deliver cancer-fighting drugs straight to a tumor. Their research was published this week in the online Early Edition of the Proceedings of the National Academy of Sciences.
