Centuries of study have yielded many theories about how the brain gives rise to human intelligence. Some think it arises from a single region or neural network. Others argue that metabolism is key. A new paper makes the case that the brain's dynamic properties -- how it is wired but also how that wiring shifts in response to changing intellectual demands -- are the best predictors of intelligence in the human brain.
The origins of social inequality might lie in the remnants of ancient Eurasia's agricultural societies, according to an article recently published in the major science journal Nature.
University of Illinois family studies researchers believed that if the attention restoration theory, which describes how interaction with natural environments can reduce mental fatigue and restore attention, worked for individuals it might also work for families to help facilitate more positive family interactions and family cohesion. They tested their theory by looking at sets of moms and daughters who were asked to take a walk together in nature and a walk in a mall.
When children become upset, showing negative emotions or behaviors, some parents become distressed, while others are able to talk their child through the difficult situation. Studies have shown that a mothers' reaction -- positive or negative -- to her child's negative emotions can predict whether her child develops the ability to effectively regulate his emotions and behavior. A new University of Illinois study explores potential predictors of mothers' supportive or non-supportive behavior during emotional challenges.
Slight changes to the system for allocating deceased-donor kidneys could result in higher rates of organ procurement and lead to more kidney transplants across the country, according to new research co-authored by an Indiana University Kelley School of Business professor.
Stink-flirting among ring-tailed lemurs come at a cost, but may also influence females in choosing a mate.
A new study published today -- World Prematurity Day -- in the American Journal of Obstetrics & Gynecology provides additional support for treatment with vaginal progesterone to reduce the risk of preterm birth, neonatal complications and infant death in pregnant women with a short cervix. A shortened cervix is the most powerful predictor of preterm birth.
Boosting activity in brain areas related to thinking and problem-solving may also protect against worsening anxiety, suggests a new study by Duke University scientists. Using noninvasive brain imaging, the researchers found that at-risk people were less likely to develop anxiety if they had higher activity in a region of the brain responsible for complex mental operations. The results may be a step towards tailoring psychological therapies to the specific brain functioning of individual patients.
Appraisal of employees often gets a bad press, but recent research suggests if it involves frequent feedback between the formal appraisal and good prior planning and communication of standards then it can be successful and appreciated by employees.
On behalf of the European Food Safety Authority, the German Federal Institute for Risk Assessment hosted a hearing of experts on the practicability of hormone measurements in toxicological studies in Berlin on Oct. 18-19, 2017.
