Management studies: Dishonesty shift Posted: 19 Sep 2017 11:04 AM PDT Lying comes more easily to people in teams: Behavioral scientists have shown in an experimental study why groups are more likely to behave unethically than individuals. |
Posted: 19 Sep 2017 11:04 AM PDT Sleep deprivation - typically administered in controlled, inpatient settings - rapidly reduces symptoms of depression in roughly half of depression patients, according the first meta-analysis on the subject in nearly 30 years. |
Brain powered: Increased physical activity among breast cancer survivors boosts cognition Posted: 19 Sep 2017 11:04 AM PDT It is estimated that up to 75 percent of breast cancer survivors experience problems with cognitive difficulties following treatments, perhaps lasting years. Currently, few science-based options are available to help. Researchers report in a pilot study of 87 female breast cancer survivors an increase in physical activity more than doubled the women's post-treatment mental processing speed. |
Proteins' role in development of spinal sensory cells redefined Posted: 19 Sep 2017 11:04 AM PDT A recent study has overturned a common belief about how a certain class of proteins in the spinal cord regulate the formation of nervous system cells -- called neurons -- during embryonic development. |
Winner takes all: Success enhances taste for luxury goods, study suggests Posted: 19 Sep 2017 09:31 AM PDT Footballers in flashy cars, City workers in Armani suits, reality TV celebrities sipping expensive champagne while sitting in hot tubs: what drives people to purchase luxury goods? New research suggests that it may be a sense of being a 'winner' -- but that contrary to expectations, it is not driven by testosterone. |
Getting emotional after failure helps you improve next time, study finds Posted: 19 Sep 2017 08:12 AM PDT Emotional responses to failure rather than cognitive ones are more effective at improving people's results for the next time they tackle the next related task, new research indicates. |
Contribution of opioid-related deaths to the change in life expectancy in the US Posted: 19 Sep 2017 08:06 AM PDT Between 2000 and 2015 in the US, life expectancy increased overall but drug-poisoning deaths, mostly related to opioids, contributed to reducing life expectancy, according to a study. |
How the shape and size of your face relates to your sexuality Posted: 19 Sep 2017 08:06 AM PDT Men and women with shorter, wider faces tend to be more sexually motivated and to have a stronger sex drive than those with faces of other dimensions. The research investigates the role that facial features play in sexual relationships and mate selection. |
Playing American football before age 12 could have long-term health effects Posted: 19 Sep 2017 07:25 AM PDT Playing American football before the age of 12 may have long-term consequences for players' mood and behavior, according to a study involving 214 professional and amateur football players. |
An interconnection between the nervous and immune system Posted: 19 Sep 2017 07:25 AM PDT Researchers have shown that the increased incidence of infections seen in spinal cord injury patients is directly linked to a disruption of the normal central nervous system. |
A piece of the puzzle: Eight autism-related mutations in one gene Posted: 19 Sep 2017 07:25 AM PDT Researchers discover a large number of clustered mutations in a single gene, TRIO, that disrupt the development of the brain's connections and likely contribute to the development of autism-spectrum disorders. The scientists also find that a sister gene linked to schizophrenia, KALRN, is inactive in early brain development, but becomes active in adolescence. |
Cell model of the brain provides new knowledge on developmental disease Posted: 19 Sep 2017 06:26 AM PDT By reprogramming skin cells into nerve cells, researchers are creating cell models of the human brain. In a new study, the researchers describe how cells from patients with the severe developmental disease lissencephaly differ from healthy cells. The method can provide vital new knowledge on difficult-to-study congenital diseases. |
Local epileptic seizure shows long distance interaction Posted: 19 Sep 2017 06:26 AM PDT An epileptic seizure may be highly local, but it also influences brain activity at a distance of over ten centimeters from the core. This, in turn, affects the active area, scientists report. |
Overcoming the brain's fortress-like barrier Posted: 19 Sep 2017 06:10 AM PDT Scientists have helped provide a way to better understand how to enable drugs to enter the brain and how cancer cells make it past the blood brain barrier. |
The brain at work: Spotting half-hidden objects Posted: 19 Sep 2017 06:10 AM PDT The human and non-human primate brain is remarkable in recognizing partially hidden objects. A study, conducted during a shape recognition task, shows as more of the shape is hidden, a brain area involved in cognition starts to sends signals to the visual cortex. The findings make the scientists wonder if this communication between different brain areas might be impaired in people with autism or Alzheimer's. Both conditions can cause confusion in cluttered surroundings and problems recognizing objects. |
Students' self-concepts of ability in math, reading predict later math, reading attainment Posted: 19 Sep 2017 06:10 AM PDT A new longitudinal study looked at how youths' self-concepts are linked to their actual academic achievement in math and reading from middle childhood to adolescence. The study found that students' self-concepts of their abilities in these two academic domains play an important role in motivating their achievements over time and across levels of achievement. |
The wrong first step to revive athletes in cardiac arrest Posted: 19 Sep 2017 06:09 AM PDT New research suggests that the main obstacle to an appropriate bystander response during athletes' cardiac arrest could be an apparently widespread myth: that 'tongue swallowing' is a common complication of sudden loss of consciousness that must be avoided or relieved at all costs to prevent death from asphyxia. |
Owners of seriously ill pets at risk of stress, anxiety and depressive symptoms Posted: 18 Sep 2017 07:22 PM PDT Owners of seriously or terminally ill pets are more likely to suffer with stress and symptoms of depression and anxiety, as well as poorer quality of life, compared with owners of healthy animals, finds a study. |
Analyzing the language of color Posted: 18 Sep 2017 01:34 PM PDT Languages tend to divide the "warm" part of the color spectrum into more color words, such as orange, yellow, and red, compared to the "cooler" regions, which include blue and green, cognitive scientists have found. This pattern, which they found across more than 100 languages, may reflect the fact that most objects that stand out in a scene are warm-colored, while cooler colors such as green and blue tend to be found in backgrounds, the researchers say. |
Fake news more likely to thrive online due to lowered fact-checking Posted: 18 Sep 2017 01:34 PM PDT Fake news is more likely to thrive online due to lowered fact-checking, according to new American research. |
Sex, aggression controlled separately in female animal brains, but overlap in male brains Posted: 18 Sep 2017 01:14 PM PDT Brain structures that control sexual and aggressive behavior in mice are wired differently in females than in males, new research shows. |
