The greater a country’s gender equality when it comes to employment, the higher the overall homicide rate, according to a Baylor study of 146 countries. What is uncertain is the "why" of that, hip, although prior research suggests it may be due to threatening male status, the researcher says.
In early August, biologist Peter Ward returned from the South Pacific with news that he encountered an old friend, one he hadn’t seen in over three decades. The University of Washington professor had seen what he considers one of the world’s rarest animals, a remote encounter that may become even more infrequent if illegal fishing practices continue.
Most people who meet a new acquaintance, or merely pass someone on the street, need only a glance to categorize that person as a particular race. But, sociologist Asia Friedman wondered, what can we learn about that automatic visual processing from people who are unable to see?
Here’s one more reason to cut down on the amount of red meat you eat. Using an animal model, researchers at Wake Forest Baptist Medical Center have found that dietary iron intake, equivalent to heavy red meat consumption, suppresses leptin, a hormone that regulates appetite.

Researchers using the IceCube Neutrino Observatory have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos. The evidence is important because it heralds a new form of astronomy using neutrinos, the nearly massless high-energy particles generated in nature’s accelerators: black holes, massive exploding stars and the energetic cores of galaxies.
A rare longfin mako shark satellite-tagged near Cuba recently “phoned home” off the U.S. Atlantic coast, say Mote Marine Laboratory scientists and colleagues who tagged the mako during the first-ever expedition to satellite-tag sharks off Cuba.
The Natufian culture, which flourished 15,000 years ago, is well known for its complex burial customs. A new study by Dr. Danny Rosenberg and Prof. Dani Nadel of the University of Haifa has discovered that these ceremonies included the use of giant boulder mortars whose pounding sound informed the community that a ceremony was being held

Physical activity has many health benefits. But contrary to common belief, exercise does not help you lose weight, public health scientists report.
Scientists have revealed never-before-seen details of how our brain sends rapid-fire messages between its cells. They mapped the 3-D atomic structure of a two-part protein complex that controls the release of signaling chemicals, called neurotransmitters, from brain cells. Understanding how cells release those signals in less than one-thousandth of a second could help launch a new wave of research on drugs for treating brain disorders.
Scientists on the Dark Energy Survey, using one of the world’s most powerful digital cameras, have discovered eight more faint celestial objects hovering near our Milky Way galaxy. If these new discoveries are representative of the entire sky, there could be many more galaxies hiding in our cosmic neighborhood.
With every breath you take, microbes have a chance of making it into your lungs. But what happens when they get there? And why do dangerous lung infections like pneumonia happen in some people, but not others? Researchers have started to answer these questions by studying the microbiome of the lungs.
Nutritional supplements can help those who are malnourished or frail to function better and live longer, a Saint Louis University research review finds.l
Across all 50 states and the District of Columbia, homicides of police officers are linked to the statewide level of gun ownership, according to a new study published in the American Journal of Public Health. The study found that police officers serving in states with high private gun ownership are more than three times more likely to be killed on the job than those on the job in states with the lowest gun ownership.
Violent video game play is linked to increased aggression in players but insufficient evidence exists about whether the link extends to criminal violence or delinquency, according to a new American Psychological Association task force report.
When fruit flies are attacked by parasites or bacteria they respond by producing offspring with greater genetic variability. These findings demonstrate that parents may purposefully alter the genotypes of their offspring to increase their chance of survival.
The first planet detected by the Gemini Planet Imager (GPI) from an international team of astronomers, which includes two scientists from the Department of Physics & Astronomy at Stony Brook University, is one outside earth’s solar system at 100 light years away. The exoplanet is being called a “young Jupiter” by the researchers because it shares many characteristics of Jupiter. A paper outlining the full findings is published in Science.
Several exploding stars have been found outside the cozy confines of galaxies, where most stars reside. These wayward supernovae are also weird because they exploded billions of years before their predicted detonations. Using archived observations from several telescopes, including the Hubble Space Telescope, astronomers have developed a theory for where these doomed stars come from and how they arrived at their current homes.
Confusing reality with imagination and losing contact with reality are two key characteristics that could play a role in the development of obsessive-compulsive disorder (OCD). This is what we learn from a study conducted by researchers at the CIUSSS de l'Est-de-l'Île-de-Montréal (Institut universitaire en santé mentale de Montréal) and the University of Montreal, the results of which were published in the Journal of Clinical Psychology.
In a phase III trial reported in the August 2015 issue of Pediatrics, the new combination vaccine was determined to be effective, safe and well-tolerated.
