Older teens, adults can learn non-verbal reasoning better than younger people Posted: 04 Nov 2016 04:19 PM PDT Older adolescents and adults can learn certain thinking skills including non-verbal reasoning more effectively than younger people, report researchers.

Female scientists collaborate differently from their male counterparts Posted: 04 Nov 2016 04:14 PM PDT Succeeding in the male-dominated science, technology, engineering and mathematics (STEM) disciplines can be very challenging for female faculty. Now, a study of the collaboration patterns of STEM faculty has found that the playing fields in some disciplines are not as level as they first appear.

Multidrug-resistant bacteria from chickens pose risk to human health Posted: 04 Nov 2016 04:13 PM PDT Isolates of a common poultry pathogen collected from animals in Indian bird markets were found to be mostly resistant to multiple classes of antibiotics. The study provides the first data on prevalence and isolation of Helicobacter pullorum in India.

Laser particles could provide sharper images of tissues Posted: 04 Nov 2016 04:09 PM PDT A new imaging technique stimulates particles to emit laser light and could create higher-resolution images of living tissues, say scientists.

Yesterday's Silk Road could be tomorrow's environmental superhighway Posted: 04 Nov 2016 04:08 PM PDT While China is building a gigantic modern-day upgrade of the famed ancient Silk Road resplendent in global cooperation in the name of economic expansion, a group of sustainability scholars point out that the Belt and Road Initiative (B&R) also could be a superhighway of environmental progress.

Detour via gravitational lens makes distant galaxy visible Posted: 04 Nov 2016 04:06 PM PDT Never before have astrophysicists measured light of such high energy from a celestial object so far away. Around 7 billion years ago, a huge explosion occurred at the black hole in the center of a galaxy. This was followed by a burst of high-intensity gamma rays. A number of telescopes have succeeded in capturing this light. An added bonus: it was thus possible to reconfirm Einstein's General Theory of Relativity, as the light rays encountered a less distant galaxy en route to Earth -- and were deflected by this so-called gravitational lens.

Insight into the seat of human consciousness Posted: 04 Nov 2016 04:05 PM PDT For millennia, philosophers have struggled to define human consciousness. Now, a team of researchers has pinpointed the regions of the brain that may play a role maintaining it.

12-week exercise program significantly improved testosterone levels in overweight, obese men Posted: 04 Nov 2016 04:05 PM PDT Twelve weeks of aerobic exercise significantly boosted testosterone levels in overweight and obese men, according to researchers. Increased levels were highest among men who exercised vigorously, report investigators.

Physical stature as a teen could predict future stock choices Posted: 04 Nov 2016 11:58 AM PDT Researchers find that people who were relatively tall as teens are more likely to invest in stocks, and those who were overweight are more risk-averse and less likely to participate in the market.

Study challenges model of Alzheimer's disease progression Posted: 04 Nov 2016 11:58 AM PDT Researchers provide unprecedented evidence that basal forebrain pathology precedes and predicts both entorhinal pathology and memory impairment in people with Alzheimer's disease.

Brain needs to be retrained after ACL injury Posted: 04 Nov 2016 11:58 AM PDT Regaining full function after an anterior cruciate ligament (ACL) injury is more than just physical -- it requires retraining the brain, say researchers.

Tsunami of stars and gas produces dazzling eye-shaped feature in galaxy Posted: 04 Nov 2016 11:58 AM PDT Astronomers have discovered a tsunami of stars and gas that is crashing midway through the disk of a spiral galaxy known as IC 2163. This colossal wave of material -- which was triggered when IC 2163 recently sideswiped another spiral galaxy dubbed NGC 2207 -- produced dazzling arcs of intense star formation that resemble a pair of eyelids.

Universal principles of phase transitions confirmed Posted: 04 Nov 2016 11:57 AM PDT New research has confirmed a decades-old theory describing the dynamics of continuous phase transitions. The findings provide the first clear demonstration of the Kibble-Zurek mechanism for a quantum phase transition in both space and time. Physicists observed the transition in gaseous cesium atoms at temperatures near absolute zero.

How each one of us contribute to Arctic sea ice melt Posted: 04 Nov 2016 11:57 AM PDT Measurements reveal the relationship between individual CO2 emissions and the Arctic's shrinking summer sea ice. For each ton of carbon dioxide that any person on our planet emits, three square metres of Arctic summer sea ice disappear.

Exercise during pregnancy may reduce markers of aging in offspring Posted: 04 Nov 2016 09:04 AM PDT Exercise during pregnancy may be as effective in protecting the next generation from age-related health risks as efforts made during the offspring's own adulthood. Researchers think that short-term lifestyle changes during pregnancy may have a long-lasting effect on future generations.

Dad’s preconception exercise may increase obesity, insulin resistance risk in offspring Posted: 04 Nov 2016 09:04 AM PDT Fathers who exercise regularly before their children are conceived may program their offspring's genes with an increased risk for metabolic disorders, according to new research. The surprising results point to the identification of epigenetic markers that may change the process of diagnosis and management of chronic disease.

Researchers find immunotherapy treatments better for advanced skin cancer Posted: 04 Nov 2016 08:36 AM PDT A research team evaluated 15 randomized controlled trials published between 2011 and 2015, assessing the benefits and harms of targeted or immune checkpoint inhibitors in 6,662 patients with cancer that had spread to the lymph nodes and surgery was not an option, or distant metastatic melanoma.

Regular exercisers still face health risks from too much sitting Posted: 04 Nov 2016 07:24 AM PDT People who meet recommended weekly physical activity guidelines are still at risk of developing chronic disease if they spend too much non-exercising time sitting. Researchers found that women sit more as they grow older, raising their risks even more.

Hate exercise? It may be in your genes Posted: 04 Nov 2016 07:24 AM PDT Genes, specifically those that modulate dopamine in the brain, may play a role in a person's propensity to embrace or avoid exercise.

Exercise may shield against the health fallout of a weeklong overindulgence Posted: 04 Nov 2016 07:24 AM PDT Previous studies show that as little as one week of overeating can impair glycemic control and insulin sensitivity. Just in time for holiday feasting, a new study finds that exercise can protect fat tissue from changes in inflammation levels and fat metabolism caused by a brief period of eating too many calories.

No iron benefit from eating placenta, study finds Posted: 04 Nov 2016 07:23 AM PDT The first clinical study of its kind finds no benefit for women who eat their placenta as a source of needed iron after giving birth.
