In less than four months since launch, the first calibrated images are being delivered by ESA's SMOS mission. These images of 'brightness temperature' translate into clear information on global variations of soil moisture and ocean salinity to advance our understanding of the water cycle.

Following a negative complete colonoscopy, those who had their colonoscopies at a hospital and had their procedures performed by a non-gastroenterologist may be at a significantly increased risk of developing subsequent colorectal cancer.

For the first time, scientists have sequenced the entire genome of the pea aphid, a notorious horticultural and agricultural pest. The findings reveal the extent of the genetic collaboration of the aphid host with its bacterial symbiont, which may account for some of the extraordinary characteristics of this insect

In patients diagnosed with clinical depression, belief in a concerned god can improve response to medical treatment, according to a paper in the Journal of Clinical Psychology.

The Proceedings of the National Academy of Sciences Editorial Board has selected six PNAS papers to receive the 2009 Cozzarelli Prize, an award that recognizes outstanding contributions to the scientific disciplines represented by the National Academy of Sciences.

Researchers have discovered that, under the right conditions, newly developed nanocrystalline materials exhibit surprising activity in the tiny spaces between the geometric clusters of atoms called nanocrystals from which they are made.

Profoundly deaf children with cochlear implants to help them to hear rate their quality of life equal to their normal-hearing peers, according to new research from UT Southwestern Medical Center auditory specialists.

In a laboratory study published in the journal Cancer Research, Scott & White Healthcare anatomic pathologist Arundhati Rao, M.D., is a co-investigator looking at the ways in which estrogen can interfere with how chemotherapy does its job in destroying breast cancer cells.

Around the time of menopause, studies have shown the threat for heart disease intensifies drastically and detecting cardiovascular disease in women is very difficult.

Grizzly bears are moving into an area along the Hudson Bay that is traditionally inhabited by polar bears, and the sightings of grizzly bears are increasing in frequency.

Researchers at the Mayo Clinic campus in Florida have found that PKC-iota (PKC-i), an oncogene important in colon and lung cancers, is over-produced in pancreatic cancer and is linked to poor patient survival. They also found that genetically inhibiting PKC-i in laboratory animals led to a significant decrease in pancreatic tumor growth and spread.

Researchers have found a new oncogenic signaling pathway by which the environmental toxin arsenic may lead to adverse health effects, including bladder cancer. These study results are published in Cancer Research, a journal of the American Association for Cancer Research.

A common Chinese and Indian folk medicine inhibits the growth of breast cancer cells, Saint Louis University researchers find.

Bitter melon extract inhibited breast cancer cell proliferation. Extract may be used as a dietary supplement to induce cancer cell death.

To help assess the potential threat of more large earthquakes in Haiti and nearby areas, scientists at the University of Texas at Austin's Institute for Geophysics are co-leading three expeditions to the country with colleagues from Purdue University, Lamont-Doherty Earth Observatory, the US Geological Survey and five other institutions. The second expedition, beginning Feb. 24, will for the first time use a scientific research vessel to examine the underwater effects of the quake.
