New drug shows promise in treating patients with ovarian cancer, even in those without BRCA mutations
The PARP inhibitor, olaparib, that has shown promise in women with an inherited mutation in their BRCA1 or BRCA2 gene (accounting for about 5-10 percent of breast and ovarian cancer cases), has, for the first time, been shown to reduce the size of tumors in a much wider group of ovarian cancer patients without these BRCA gene mutations.

In the Himalayan peaks, UC tests designs to improve researchers' lives in the field
University of Cincinnati prototype designs to improve the lives of researchers when they are

Iberian lynx not doomed by its genetics
The low genetic diversity of the Iberian lynx -- the most endangered carnivore in Europe -- may not decrease the species' chance of survival, according to new research by geneticists.

Imaging probe allows noninvasive detection of dangerous heart-valve infection
A novel imaging probe developed by Massachusetts General Hospital investigators may make it possible to diagnose accurately a dangerous infection of the heart valves.

Newly discovered cell mechanism uses amplified nitric oxide to fight C. diff
Research encompassing Case Western Reserve University School of Medicine and University Hospitals Case Medical Center, has uncovered a natural defense mechanism that is capable of inactivating the toxin that spreads Clostridium difficile, or C. diff, an increasingly common bacterial infection in hospitals.

Less-educated Americans turning their backs on religion
While religious service attendance has decreased for all white Americans since the early 1970s, the rate of decline has been more than twice as high for those without college degrees compared to those who graduated from college, according to new research to be presented at the 106th Annual Meeting of the American Sociological Association.

Sweet insight: Discovery could speed drug development
In a new study, University of Wisconsin-Madison researchers have described a simple process to separate sugars from a carrier molecule, then attach them to a drug or other chemical.

Mothers' poor health impairs children's well-being, not only due to genetics
Disadvantaged, unhealthy mothers are much more likely to have sickly children than are disadvantaged moms who are relatively healthy -- and this is not only due to genetics, suggests new research to be presented at the 106th Annual Meeting of the American Sociological Association.

Radical overhaul of farming could be 'game-changer' for global food security
According to new research released today at the World Water Week in Stockholm, a radical transformation in the way farming and natural systems interact could simultaneously boost food production and protect the environment.

New defense discovered against common hospital-acquired infection
Researchers have discovered a key mechanism used by intestinal cells to defend themselves against one of the world's most common hospital-acquired bacterial infections -- a mechanism they think they can exploit to produce a therapy to protect against the effects of the antibiotic-resistant bacteria.

Newly discovered Icelandic current could change North Atlantic climate picture
An international team of researchers, including physical oceanographers from the Woods Hole Oceanographic Institution, has confirmed the presence of a deep-reaching ocean circulation system off Iceland that could significantly influence the ocean's response to climate change in previously unforeseen ways.

Major ALS breakthrough
The cause of ALS, a fatal disease that paralyzes its victims, has long eluded scientists.

AUVSI names inaugural winner of 'Member of the Year' award
The Association for Unmanned Vehicle Systems International -- AUVSI -- has named professor Mark Patterson of the Virginia Institute of Marine Science as the inaugural winner of its

The secret life of millipedes
Male adult helminthomorph millipedes usually have one or two pairs of legs from their seventh segment modified into sexual appendages.

Study: New job trends reproducing old forms of gender inequality
Jobs that come with large paychecks but long work hours are slowing the gains women have made since the late 70s in narrowing the gender wage gap.

At last, a reason why stress causes DNA damage
For years, researchers have published papers that associate chronic stress with chromosomal damage.

Study identifies new way to treat common hospital-acquired infection
Researchers have discovered a molecular process by which the body can defend against the effects of Clostridium difficile, an intestinal disease that impacts several million in the U.S. each year.
