  • 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.

  • Bipolar disorder discovery at the nano level
    A nano-sized discovery helps explain how bipolar disorder affects the brain and could one day lead to new drug therapies to treat the mental illness, researchers report.
