Optics may speed breast cancer diagnosis
U. ILLINOIS (US)—Waiting for laboratory results is often one of the most stressful aspects of a breast cancer diagnosis. A new optical imaging system aims to ease that stress by giving doctors performing lumpectomies real-time information on breast cancer tissue margins while still in the operating room. (more…)

MS aggressive in kids, yet slow to disable
U. BUFFALO (US)—MRI brain scans show that multiple sclerosis is more aggressive and causes more brain lesions in patients diagnosed in childhood. However, researchers report that disabilities develop at a slower pace compared to those diagnosed with MS as adults. (more…)

Doctors take 3-D tour before surgery
IOWA STATE (US)—James Oliver picked up an Xbox game controller, looked up to a video screen, and zipped through a patient’s chest cavity for an up-close look at the bottom of the heart. Oliver was using new software that allows doctors to take an accurate, 3-D tour of a patient’s anatomy in advance of surgery. (more…)

Surgery-free diagnosis with optical biopsy
U. FLORIDA (US)—Most biopsies following mammograms reveal benign abnormalities, not cancer, but women still have to endure medical costs, stress, and potential complications that accompany invasive procedures. A new tool could make it possible for women to have biopsies without surgical intervention. (more…)

Cassini reshapes view of solar system
JOHNS HOPKINS (US)—It turns out that the solar system may look more like a basketball than a comet. Images from one of the sensors on NASA’s Cassini spacecraft suggest that the heliosphere—the region of our sun’s influence—may not have the comet-like shape predicted by existing models. (more…)

Messenger makes final Mercury flyby
U. COLORADO (US)—NASA’s Messenger spacecraft will zip by Mercury for the third and final time today, September 29, cruising within 142 miles of the planet’s surface at more than 100,000 mph. Messenger will take high-resolution color images of the surface terrain before making a clever gravity-assist maneuver that will steer it into orbit around the rocky planet beginning in March 2011.

Monkey brain signals mental wanderlust
DUKE (US)—Knowing when to stay with what’s familiar or when to search for something new can be tricky, especially for those with conditions such as Alzheimer’s disease. Using brain scans, researchers are able to predict when monkeys will switch from exploiting a known resource to exploring their options. (more…)

E. coli travel using kayak-paddle motion
YALE (US)—Engineers have for the first time observed and tracked E. coli bacteria moving in a liquid medium with a motion similar to that of a kayak paddle. The findings offer a clearer picture of how bacteria move from place to place and, potentially, how to keep them from spreading. (more…)

Candid camera at the nanoscale
“This is engineering at the ultimate atomistic limit,” says V. Ara Apkarian, who is leading a team attempting to record the first time-lapse images of single molecules. “There’s no question the tools that enable the observation and manipulation of one molecule at a time will be the pillars on which the field of nanotechnology will be built.”

New way to size up placentas
“In this study, we showed that the equation predicted the actual placental weight with an accuracy of up to 89 percent,” says Harvey Kliman. “The method works best during the second and early third trimesters, just when routine ultrasound screening is done on many women in the U.S.”
