Extreme Space Weather at Mercury Blasts the Planet’s Poles

ANN ARBOR, Mich.— The solar wind sandblasts the surface of planet Mercury at its poles, according to new data from a University of Michigan instrument on board NASA’s MESSENGER spacecraft.

The sodium and oxygen particles the blistering solar wind kicks up are the primary components of Mercury’s wispy atmosphere, or “exosphere,” the new findings assert. Through interacting with the solar wind, they become charged in a mechanism that’s similar to the one that generates the Aurora Borealis on Earth. (more…)

Close Up Look at a Microbial Vaccination Program

*Berkeley Lab Researchers Resolve Sub-nanometer Structure of Cascade, an Ally for Human Immune System*

A complex of proteins in the bacterium E.coli that plays a critical role in defending the microbe from viruses and other invaders has been discovered to have the shape of a seahorse by researchers with the U.S Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). This discovery holds far more implications for your own health than you might think.

In its never-ending battle to protect you from infections by bacteria, viruses, toxins and other invasive elements, your immune system has an important ally – many allies in fact. By the time you reach adulthood, some 90-percent of the cells in your body are microbial. These microbes – collectively known as the microbiome – play a critical role in preserving the health of their human host. (more…)

Researchers Develop System that Finds Prostate Cancer Metastases Earlier

Researchers at UCLA’s Jonsson Comprehensive Cancer Center have developed a way to image the spread of a dangerous form of prostate cancer earlier than today’s conventional imaging techniques. The new method may allow oncologists to find and treat metastases more quickly and give patients a better chance at survival.

The gene-based imaging system targets castration-resistant prostate cancer, an aggressive form of the disease that has become resistant to the hormone treatment known as androgen-deprivation therapy. Once this treatment no longer works, the cancer will progress within 12 to 18 months, and the prognosis becomes grim, said senior study author Dr. Lily Wu, a professor of molecular and medical pharmacology and a Jonsson Cancer Center researcher.

NASA Leads Study of Unprecedented Arctic Ozone Loss

PASADENA, Calif. – A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere.

The study, published online Sunday, Oct. 2, in the journal Nature, finds the amount of ozone destroyed in the Arctic in 2011 was comparable to that seen in some years in the Antarctic, where an ozone “hole” has formed each spring since the mid-1980s. The stratospheric ozone layer, extending from about 10 to 20 miles (15 to 35 kilometers) above the surface, protects life on Earth from the sun’s harmful ultraviolet rays. (more…)
