Action video games bolster sensorimotor skills, study finds

Posted: 17 Oct 2014 08:11 AM PDT

People who play action video games such as Call of Duty or Assassin's Creed seem to learn a new sensorimotor skill more quickly than non-gamers do, psychology researchers have found.

How the brain leads us to believe we have sharp vision

Posted: 17 Oct 2014 07:13 AM PDT

We assume that we can see the world around us in sharp detail. In fact, our eyes can only process a fraction of our surroundings precisely. In a series of experiments, psychologists have been investigating how the brain fools us into believing that we see in sharp detail.

Scientific breakthrough will help design antibiotics of the future

Posted: 17 Oct 2014 07:13 AM PDT

Computer simulations have been used to show how bacteria are able to destroy antibiotics -- a breakthrough which will help develop drugs which can effectively tackle infections in the future.

Blinded by non-science: Trivial scientific information increases trust in products

Posted: 17 Oct 2014 07:12 AM PDT

Beware of trivial graphs and formulas, warns new research. The study found trivial graphs or formulas accompanying medical information can lead consumers to believe products are more effective.

'Red effect' sparks interest in female monkeys

Posted: 17 Oct 2014 07:12 AM PDT

Recent studies showed that the color red tends increase our attraction toward others, feelings of jealousy, and even reaction times. Now, new research shows that female monkeys also respond to the color red, suggesting that biology, rather than our culture, may play the fundamental role in our "red" reactions.

Improving bladder function among people with spinal cord injuries

Posted: 17 Oct 2014 06:31 AM PDT

New research may lead to dramatically fewer bladder infections following spinal cord injuries and other traumatic injuries -- infections that can cause kidney damage, and even death, scientists report.

Physicists sound warning to 'nail beauty fanatics'

Posted: 17 Oct 2014 06:31 AM PDT

The daily trimming of fingernails and toenails to make them more aesthetically pleasing could be detrimental and potentially lead to serious nail conditions.

Cystic Fibrosis lung infection: Scientists open black box on bacterial growth

Posted: 17 Oct 2014 06:31 AM PDT

Researchers have shown for the first time how bacteria can grow directly in the lungs of Cystic fibrosis patients, giving them the opportunity to get tremendous insights into bacteria behavior and growth in chronic infections.

Divide and conquer: Novel trick helps rare pathogen infect healthy people

Posted: 17 Oct 2014 06:31 AM PDT

New research into a rare pathogen has shown how a unique evolutionary trait allows it to infect even the healthiest of hosts through a smart solution to the body's immune response against it, scientists report.

High-speed evolution in the lab: Geneticists evaluate cost-effective genome analysis

Posted: 17 Oct 2014 06:29 AM PDT

Life implies change. And this holds true for genes as well. Organisms require a flexible genome in order to adapt to changes in the local environment. Researchers want to know why individuals differ from each other and how these differences are encoded in the DNA. In two review papers, they discuss why DNA sequencing of entire groups can be an efficient and cost-effective way to answer these questions. 

Emergency aid for overdoses

Posted: 17 Oct 2014 06:29 AM PDT

Every minute counts in the event of an overdose. Now, researchers have developed an agent to filter out toxins from the body more quickly and efficiently. It can also be used for dialysis in patients suffering from hepatic failure.

Tailored 'activity coaching' by smartphone

Posted: 17 Oct 2014 06:29 AM PDT

Today's smartphone user can obtain a lot of data about his or her health, thanks to built-in or separate sensors. Researchers now take this health monitoring to a higher level. Using the system he developed, the smartphone also acts as an 'activity coach': it advices the user to walk or take a rest. In what way the user wants to be addressed, is typically something the system learns by itself.

Presence of enzyme may worsen effects of spinal cord injury and impair long-term recovery

Posted: 17 Oct 2014 06:29 AM PDT

Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma. Through a series of experiments, researchers suggest that matrix metalloproteinase-3 (MMP-3) plays a pivotal role in disruption of the brain/spinal cord barrier (BSCB), cell death, and functional deficits after SCI. This link also presents new therapeutic possibilities.

First step: From human cells to tissue-engineered esophagus

Posted: 17 Oct 2014 06:26 AM PDT

In a first step toward future human therapies, researchers have shown that esophageal tissue can be grown in vivo from both human and mouse cells.

Major benefits for students who attend live theater, study finds

Posted: 16 Oct 2014 01:59 PM PDT

Field trips to live theater enhance literary knowledge, tolerance, and empathy among students, according to a study. The research team found that reading and watching movies of Hamlet and A Christmas Carol could not account for the increase in knowledge experienced by students who attended live performances of the plays. Students who attended live performances of the play also scored higher on the study's tolerance measure than the control group by a moderately large margin and were better able to recognize and appreciate what other people think and feel.

Misfolded proteins clump together in a surprising place

Posted: 16 Oct 2014 09:32 AM PDT

A surprising finding about the aggregates of misfolded cellular proteins has been made. Patients with Parkinson's disease, cardiovascular disease, and cystic fibrosis may have something in common: cells in their disease-affected tissues may produce misfolded proteins that are incapable of functioning normally, scientists say. In a recent article, they report where the misfolded proteins clump together in a cell, and how the cell can prevent the passage of these defective molecules to its daughter cell.

Public health in the 21st century

Posted: 16 Oct 2014 08:21 AM PDT

Although disease outbreaks and epidemics drawing worldwide attention emphasize the importance and acute need for public health professionals, the world faces a longer-term challenge -- a public health workforce that is truly effective in the 21st century. In a new article, experts address critical challenges to public health, from workforce development, capacity building, partnership and collaborations, and changes and needs in workforce composition.

Youth suicide: More early detection, better coordination are needed

Posted: 16 Oct 2014 07:04 AM PDT

Although progress has been made in recent years, the matter of youth suicide in Quebec still needs to be more effectively addressed. In fact, a new study shows that more lives could be saved through early detection and increased public awareness and information sharing among professionals.
