Women Get Pull Requests Accepted More (Except When You Know They're Women)

Slashdot - Wed, 10/02/2016 - 8:01pm
An anonymous reader writes: In the largest study of gender bias [in programming] to date, researchers found that women tend to have their pull requests accepted at a higher rate than men, across a variety of programming languages. This, despite the finding that their pull requests are larger and less likely to serve an immediate project need. At the same time, when the gender of the women is identifiable (as opposed to hidden), their pull requests are accepted less often than men's.

Research finds new target in search for why statin drugs sometimes cause problems for some patients

Science Daily - Wed, 10/02/2016 - 7:34pm
Statin drugs interact with a gap junction protein called GJC3 that releases ATP, a major signaling molecule for inflammation in the body, new research shows. This discovery provides a significant new target in the search for why statin drugs can sometimes cause harmful effects such as muscle toxicity in some patients.

Forget butterflies and bees, box like an ant

Science Daily - Wed, 10/02/2016 - 7:27pm
Boxer Muhammad Ali famously declared his intent to 'float like a butterfly and sting like a bee,' but perhaps boxers should look to another type of insect for inspiration: the trap-jaw ant. In a new study, entomologists measured the speed at which different species of trap-jaw ants strike one another during antenna-boxing bouts.

Lipid-based diets effectively combat Alzheimer's disease in mouse model

Science Daily - Wed, 10/02/2016 - 7:27pm
Researchers have devised several lipid-based diets aimed at slowing down progression and relieving symptoms of Alzheimer's disease (AD). It is generally accepted that lifestyle and particularly dietary habits influence mental health, and prevalence and progression of AD. Numerous epidemiological studies have revealed profitable effects of dietary intake of especially fish oil on cognitive decline during aging and dementia.

Research uncovers more inherited genetic mutations linked to ovarian cancer

Science Daily - Wed, 10/02/2016 - 6:54pm
Previous research has established a link between genetic mutations in the BRCA1 and BRCA2 genes to an increased risk of developing ovarian, fallopian tube or peritoneal cancer in women. A recent publication documents the efforts of a team of researchers to determine if inherited genetic mutations other than BRCA1 and BRCA2 can also put a woman at risk of developing these diseases.

Study challenges widely accepted theory of Yellowstone formation

Science Daily - Wed, 10/02/2016 - 6:53pm
Understanding the complex geological processes that form supervolcanoes could ultimately help geologists determine what triggers their eruptions. A new study using an advanced computer model casts doubt on previously held theories about the Yellowstone supervolcano's origins, adding to the mystery of Yellowstone's formation.

Healing the soil

Science Daily - Wed, 10/02/2016 - 6:53pm
Chicago's history of industrialization and urbanization left its mark on the soil. Soil acts as a sponge, and can host contaminants for years. In Chicago, the waste from industrial manufacturing causes undesirable toxic organic chemicals, heavy metals, and other chemicals to linger in the soil. A non-profit youth development center hopes to repurpose the lots into useful spaces for the community. However, the poor quality soils in the lots create challenges.

Study sheds light on source of drug addicts risk-taking behavior

Science Daily - Wed, 10/02/2016 - 6:52pm
New insight has been gained into how the brains of drug addicts may be wired differently. The findings show that while drug users have very strong motivation to seek out 'rewards,' they exhibit an impaired ability to adjust their behavior and are less fulfilled once they have achieved what they desire. This disconnect between the craving for a drug and inability to regulate behavior may be key to breaking the cycle of addiction.

Leukemia's surroundings key to its growth

Science Daily - Wed, 10/02/2016 - 6:52pm
A type of cancer found primarily in children can grow only when signaled to do so by other nearby cells that are noncancerous, new research shows. The study contributes to a growing body of research that implicates the environment around a cancer in its spread -- an area of study that holds promise for new alternatives to treat the disease.

Water plus magma equals increased explosivity

Science Daily - Wed, 10/02/2016 - 6:52pm
When water interacts with magma, it can dramatically increase the explosivity of the eruption. However, water in the eruption cloud can also increase the rate at which the particles aggregate into larger clumps, allowing them to settle out faster. The five-week-long 2008 Okmok eruption in the Aleutian Islands of Alaska was explosive due to the interaction of the magma with the abundant water inside the caldera.

Study of Asian common toad reveals three divergent groups

Science Daily - Wed, 10/02/2016 - 6:49pm
A research project has tested the hypothesis that Asian common toad populations across Southeast Asia are genetically similar owing to their commensal nature and high dispersive ability. To the researchers' surprise, three genetically divergent groups of toads were found, each in a different geographic area (mainland Southeast Asia, coastal Myanmar and the islands of Java and Sumatra).
