Picking up a second language is predicted by ability to learn patterns

Some people seem to pick up a second language with relative ease, while others have a much more difficult time. Now, a new study suggests that learning to understand and read a second language may be driven, at least in part, by our ability to pick up on statistical regularities.

The study is published in Psychological Science, a journal of the Association for Psychological Science.

Preventing 'traffic jams' in brain cells

"Our major discovery is that presenilin has a novel role, which is to control the movement of motor proteins along neuronal highways," said Gunawardena, an assistant professor of biological sciences. "If this regulation/control is lost, then things can go wrong. This is the first time a protein that functions as a controller of motors has been reported.

Men, women lie about sex to match gender expectations

COLUMBUS, Ohio – People will lie about their sexual behavior to match cultural expectations about how men or women should act – even though they wouldn't distort other gender-related behaviors, new research suggests.

The study found that men were willing to admit that they sometimes engaged in behaviors seen by college students as more appropriate for women, such as writing poetry. The same was true for women, who didn't hide the fact that they told obscene jokes, or sometimes participated in other "male-type" deeds.

Art appreciation is measureable

Have you experienced seeing a painting or a play that has left you with no feelings whatsoever, whilst a friend thought it was beautiful and meaningful? Experts have argued for years about the feasibility of researching art appreciation, and what should be taken into consideration.

Childhood bullying increases the propensity to self-harm during adolescence

A new study has proven that being bullied during childhood directly increases the likelihood of self- harm in late adolescence.

The analysis, led by researchers from the University of Warwick in association with colleagues at the University of Bristol, highlights that being bullied at primary school age can cause enough distress to significantly increase the risk of self-harming in later adolescence.

Analysis of medical images improved to facilitate the study of psychotic disorders

A team of researchers from the UPNA/NUP-Public University of Navarre has developed new super-resolution and segmentation methods for magnetic resonance images so that they can be applied to the structural study of psychosis. The aim is to be able to identify the differences that are produced in specific parts of the brain in psychotic patients with respect to their healthy relatives or other people.

Aspirin triggered resolvin protects against cognitive decline after surgery

Resolvins are molecules naturally produced by the body from omega-3 fatty acids – a process that can be jumpstarted by common aspirin. In a new study, published in The FASEB Journal, researchers at Karolinska Institutet describe how resolvins could protect against the cognitive impairment that often affects recovery of surgical and critically ill patients. The study adds new knowledge on how peripheral surgery affects the brain and neuronal function contributing to the processes of cognitive decline.

Preterm birth affects ability to solve complex cognitive tasks

Being born preterm goes hand in hand with an increased risk for neuro-cognitive deficits. Psychologists from the Ruhr-Universität Bochum and the University of Warwick, UK have investigated the relation between the duration of pregnancy and cognitive abilities under varying work load conditions. "Cognitive performance deficits of children dramatically increase as cognitive workload of tasks increases and pregnancy duration decreases," says Dr Julia Jäkel from the Ruhr-Universität.

'Preferred retinal location' may aid rehabilitation in patients with central vision loss

Philadelphia, Pa. (May 28, 2013) - Perceptual learning techniques may provide a useful new approach to rehabilitation in patients with central vision loss—taking advantage of visual plasticity that persists even in old age, according to a special article in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Stem cell injections improve spinal injuries in rats

An international team led by researchers at the University of California, San Diego School of Medicine reports that a single injection of human neural stem cells produced neuronal regeneration and improvement of function and mobility in rats impaired by an acute spinal cord injury (SCI).

The findings are published in the May 28, 2013 online issue of Stem Cell Research & Therapy.

Spine function improves following cell replacement therapy with fetal human stem cells

Human foetal stem cell grafts improve both motor and sensory functions in rats suffering from a spinal cord injury, according to research published this week in BioMed Central's open access journal Stem Cell Research and Therapy. This cell replacement therapy also improves the structural integrity of the spine, providing a functional relay through the injury site. The research gives hope for the treatment of spinal cord injuries in humans.

Down syndrome neurons grown from stem cells show signature problems

Madison, Wis. – Down syndrome, the most common genetic form of intellectual disability, results from an extra copy of one chromosome. Although people with Down syndrome experience intellectual difficulties and other problems, scientists have had trouble identifying why that extra chromosome causes such widespread effects.

In new research published this week, Anita Bhattacharyya, a neuroscientist at the Waisman Center at the University of Wisconsin-Madison, reports on brain cells that were grown from skin cells of individuals with Down syndrome.

Pitt team finds mechanism that causes noise-induced tinnitus and drug that can prevent it

PITTSBURGH, May 27, 2013 – An epilepsy drug shows promise in an animal model at preventing tinnitus from developing after exposure to loud noise, according to a new study by researchers at the University of Pittsburgh School of Medicine. The findings, reported this week in the early online version of the Proceedings of the National Academy of Sciences, reveal for the first time the reason the chronic and sometimes debilitating condition occurs.

Healthy habits die hard: In times of stress, people lean on established routines -- even healthy ones

Stress and exhaustion may turn us into zombies, but a novel study shows that mindless behavior doesn't just lead to overeating and shopping sprees — it can also cause us to stick with behaviors that are good for us.
