Titan glowing at dusk and dawn
New maps of Saturn's moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one.

Finally: Missing link between vitamin D, prostate cancer
A new study offers compelling evidence that inflammation may be the link between vitamin D and prostate cancer. Specifically, the study shows that the gene GDF-15, known to be upregulated by vitamin D, is notably absent in samples of human prostate cancer driven by inflammation.

Real-time tracking system developed to monitor dangerous bacteria inside body
Combining a PET scanner with a new chemical tracer that selectively tags specific types of bacteria, researchers working with mice report they have devised a way to detect and monitor in real time infections with dangerous Gram-negative bacteria. These increasingly drug-resistant bacteria are responsible for a range of diseases, including fatal pneumonias and various bloodstream or solid-organ infections acquired in and outside the hospital.

Paralyzed patients have weaker bones, higher risk of fractures than expected
People paralyzed by spinal cord injuries lose mechanical strength in their leg bones faster, and more significantly, than previously believed, putting them at greater risk for fractures from minor stresses, according to a study by researchers. The results suggest that physicians should begin therapies for such patients sooner to maintain bone mass and strength, and should think beyond standard bone density tests when assessing fracture risk in osteoporosis patients.

New ultra-thin 3-D display technology promises greater energy efficiency
Researchers have devised an ultra-thin LCD screen that operates without a power source, making it a compact, energy-efficient way to display visual information. The technology may one day have applications in products such as e-book readers, flexible displays or as a security measure on credit cards.

Wild chimps use innovative strategies to raid neighboring agricultural fields undetected
Wild chimpanzees living in a disturbed habitat may use innovative strategies, like foraging crops at night, to coexist with nearby human activities.

Thermal paper cash register receipts account for high bisphenol A (BPA) levels in humans
BPA from thermal paper used in cash register receipts accounts for high levels of BPA in humans. Subjects studied showed a rapid increase of BPA in their blood after using a skin care product and then touching a store receipt with BPA.

Baby cries show evidence of cocaine exposure during pregnancy
A new study provides the first known evidence of how a similar acoustic characteristic in the cry sounds of human infants and rat pups may be used to detect the harmful effects of prenatal cocaine exposure on nervous system development.
