Breastfeeding, tubal ligation – also known as having one’s “tubes tied” – and oral contraceptives may lower the risk of ovarian cancer for some women with BRCA gene mutations, according to a comprehensive analysis from a team at the University of Pennsylvania's Basser Research Center for BRCA and the Abramson Cancer Center. The findings, a meta-analysis of 44 existing peer-reviewed studies, are published in the Journal of the National Cancer Institute.
Jason Jones, assistant professor of Japanese at UWM, says pop culture has helped to erase the more complicated character of the original 1954 Godzilla.
Forgiving ourselves for hurting another is easier if we first make amends — thus giving our inner selves a “moral OK,” according to Baylor University psychology researchers.
Scientists re-examined 100 world-wide monitoring studies and were surprised to discover that, over decades, the number of species in many places has not changed much—or has increased. But the researchers did discover that almost 80% of the communities showed changes in species composition. This shows that a rapid global turnover of species is happening, resulting in novel biological communities. The scientists conclude that biodiversity change may be as large a concern as biodiversity loss.
Using new stem cell technology, scientists at the Salk Institute have shown that neurons generated from the skin cells of people with schizophrenia behave strangely in early developmental stages, providing a hint as to ways to detect and potentially treat the disease early.
Men who have been incarcerated and released are more than twice as likely to die prematurely as those who haven't been imprisoned, according to a Georgia State University criminologist.

St. Jude Children’s Research Hospital scientists studying two rare, inherited childhood neurodegenerative disorders have identified a new, possibly common source of DNA damage that may play a role in other neurodegenerative diseases, cancer and aging. The findings appear in the current issue of the scientific journal Nature Neuroscience.
A Virginia Tech team of researchers has proven that homemade, inexpensive stink bug traps crafted from simple household items outshine pricier models designed to kill the invasive, annoying bugs.
What is the secret to aging more slowly and living longer? Not antioxidants, apparently. Many people believe that free radicals, the sometimes-toxic molecules produced by our bodies as we process oxygen, are the culprit behind aging. Yet a number of studies in recent years have produced evidence that the opposite may be true.
A newly identified difference between the brains of women and men with multiple sclerosis (MS) may help explain why so many more women than men get the disease, researchers at Washington University School of Medicine in St. Louis report.

Viewing partisan news reports from both the conservative and liberal viewpoints doesn’t make people more accepting of citizens on the other side of the political fence.
A smartphone app that monitors subtle qualities of a person’s voice during everyday phone conversations shows promise for detecting early signs of mood changes in people with bipolar disorder. While the app still needs much testing before widespread use, early results from a small group of patients show its potential to monitor moods while protecting privacy.
A new study released May 7 in the journal PLOS ONE suggests that people who survived the medieval mass-killing plague known as the Black Death lived significantly longer and were healthier than people who lived before the epidemic struck in 1347. University of South Carolina researcher Sharon DeWitte's findings have important implications for understanding emerging diseases and how they impact the health of individuals and populations of people.
Using thermal imagery, researchers can now see what lies beneath the dirt-covered desert landscape. A team of researchers from the University of North Florida and the University of Arkansas have successfully used drones to unearth a 1,000-year-old village in northwestern New Mexico, revealing never-seen-before structures, unique insight into who lived there and what the area was like.
A University of Utah-led team discovered a “hypervelocity star” that is the closest, second-brightest and among the largest of 20 found so far. Speeding at more than 1 million mph, the star may provide clues about the supermassive black hole at the center of our Milky Way and the halo of mysterious “dark matter” surrounding the galaxy, astronomers say.
Investigators at the Cedars-Sinai Heart Institute – whose previous research showed that cardiac stem cell therapy reduces scarring and regenerates healthy tissue after a heart attack in humans – have identified components of those stem cells responsible for the beneficial effects.
In one of the greatest feats of endurance in the biological world, millions of tiny songbirds — many weighing less than an ounce — migrate thousands of miles to Central and South America each year. Now scientists are finding out how these featherweights do it: using elliptical routes that take advantage of prevailing wind patterns to save calories.
Chimpanzees have almost the same personality traits as humans, and they are structured almost identically, according to new work led by researchers at Georgia State University.
Researchers have found that the phenomenon of “face pareidolia”--where onlookers report seeing images of Jesus, Virgin Mary, or Elvis in objects such as toasts, shrouds, and clouds--is normal and based on physical causes.
Researchers at the University of California, San Diego School of Medicine have discovered a genetic risk factor for premature birth. The risk factor is related to a gene that codes for a protein that the scientists have found helps the body’s immune cells recognize and fight Group B Streptococcus (GBS) bacteria.
Boston, MA — In the first four years after Massachusetts instituted comprehensive health reform in 2006, mortality in the state decreased by 2.9% compared with similar populations in states that didn’t expand health coverage, according to a study led by Harvard School of Public Health. The researchers estimated Massachusetts’ health reform law has prevented about 320 deaths per year—one life saved for each 830 people gaining insurance.
Co-evolutionary changes in species may reverse traditional predator-prey population cycles, creating the appearance that prey are eating the predators, according to a study to be published in the journal Proceedings of the National Academy of Sciences
Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research led by NCAR. The detailed study shows that Americans face the risk of a 70 percent increase in unhealthy summertime ozone levels by 2050.
In the first study of its kind, researchers have determined that spending time with horses eases symptoms of Alzheimer’s dementia.
Women have no effect on mice, but men cause a stress level comparable to a three-minute swim. Results indicate that researchers should account for these variables.
The reporters, editors and producers who put out the news every day are less satisfied with their work, say they have less autonomy in their work and tend to believe that journalism is headed in the wrong direction, according to the initial findings of "The American Journalist in the Digital Age," a representative survey of U.S. journalists conducted by the Indiana University School of Journalism.
-- Men who begin taking statins after prostate cancer surgery are less likely to have a recurrence of their cancer, according to a retrospective analysis led by researchers at Duke Medicine.
More than a mile beneath the ocean’s surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.
Killer whales and other marine mammals likely hear sonar signals more than we’ve known. That’s because commercially available sonar systems, which are designed to create signals beyond the range of hearing of such animals, also emit signals known to be within their hearing range, scientists have discovered.
Two teams of astronomers using the NASA's Hubble Space Telescope have discovered three distant exploding stars that have been magnified by the immense gravity of foreground galaxy clusters, which act like "cosmic lenses." These supernovae offer astronomers a powerful tool to check the prescription of these massive lenses, and may be the next best thing to a giant cosmic eye chart.
Engineering researchers at the University of Arkansas have developed a wireless health-monitoring system that detects early signs of traumatic brain injury by continuously monitoring various brain and neural functions.

The value of soybeans in Mississippi expanded $1 billion in six years, largely through the efforts of the Extension Service to make farmers better managers. The story takes a historic look at this significant row crop.
The biggest-sized junkyard in the world orbits it, and a University of Alabama in Huntsville (UAH) aerospace systems engineering graduate student says it’s time to get active about reducing the debris field before we reach a tipping point beyond which we may not be able to do much.
To solve a puzzle, you need to recognize shapes, patterns and a particular kind of order. In much the same way, researchers at McGill University have discovered that the 3D shape of a leukemia cell’s genome holds a key to solving the puzzle of human diseases. The researchers report their findings in the open access journal Genome Biology.
Cancer patients who have higher levels of vitamin D when they are diagnosed tend to have better survival rates and remain in remission longer than patients who are vitamin D-deficient, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).
Populations of large wildlife are declining around the world, while zoonotic diseases (those transmitted from animals to humans) are on the rise. A team of Smithsonian scientists and colleagues have discovered a possible link between the two. They found that in East Africa, the loss of large wildlife directly correlated with a significant increase in rodents, which often carry disease-causing bacteria dangerous to humans.
A research team at Kansas State University recently confirmed that insects, such as house flies and cockroaches, can carry antibiotic-resistant bacteria from places such as food animal farms and wastewater treatment facilities, and disseminate them to urban areas. The transmission could be a contributor to the increasing problem with human antibiotic resistance.
Working together, Johns Hopkins biomedical engineers and neurosurgeons report that they have created tiny, biodegradable “nanoparticles” able to carry DNA to brain cancer cells in mice.
Labs at Rice University and Georgia Tech have tested the fracture toughness of graphene for the first time by making and measuring "pre-cracks" under stress. The results show the material to be somewhat brittle.
