Groundbreaking research by a team of UCLA physicians and engineers demonstrates that prostate cancer — long identifiable only through painful, hit-or-miss biopsies — can be diagnosed far more easily and accurately using a new image-guided, targeted biopsy procedure.

Traditionally, prostate tumors have been found through so-called blind biopsies, in which tissue samples are taken systematically from the entire prostate in the hopes of locating a piece of tumor — a technique that dates back to the 1980s. But the cancer now appears detectable by direct sampling of tumor spots found using magnetic resonance imaging, or MRI, in combination with real-time ultrasound, the researchers say. (more…)

*Three volunteers who make a difference*

A murmur runs through the audience as Bob Kriel withdraws his gloved hand from a darkened cage in the front of a small lecture room.

On the glove sits Bubo, a great horned owl. With his piercing eyes and imperial demeanor, this large bird with mottled gray feathers instantly dominates the room.

Kriel, a retired physician who still does clinical research at the University of Minnesota, volunteers weekly at the U’s Raptor Center, where sick and injured birds of prey receive treatment. (more…)

Two spacecraft are now beginning to study the moon’s environment as part of NASA’s ARTEMIS mission, whose principal investigator is Vassilis Angelopoulos, a UCLA professor of Earth and space sciences.

One of these satellites has been in the lunar environment since Aug. 25, and the second arrived Oct. 22, marking the start of the ARTEMIS mission to gather new scientific data in the sun-Earth-moon environment.
