Attention, college students cramming between midterms and finals: Binging on soda and sweets for as little as six weeks may make you stupid.
A new UCLA rat study is the first to show how a diet steadily high in fructose slows the brain, hampering memory and learning — and how omega-3 fatty acids can counteract the disruption. The peer-reviewed Journal of Physiology publishes the findings in its May 15 edition.
ITHACA, N.Y. – Genetic factors explain some of the variation in a wide range of people's political attitudes and economic decisions – such as preferences toward environmental policy and financial risk taking – but most associations with specific genetic variants are likely to be very small, according to a new study led by Cornell University economics professor Daniel Benjamin.
A novel mechanism for anxiety behaviors, including a previously unrecognized inhibitory brain signal, may inspire new strategies for treating psychiatric disorders, University of Chicago researchers report.
By testing the controversial role of a gene called Glo1 in anxiety, scientists uncovered a new inhibitory factor in the brain: the metabolic by-product methylglyoxal. The system offers a tantalizing new target for drugs designed to treat conditions such as anxiety disorder, epilepsy, and sleep disorders.
To detour around the block in this patient's C7 spinal cord injury and return hand function below the level of the injury, Mackinnon operated in the upper arms. There, the working nerves that connect above the injury and the non-working nerves that connect below the injury run parallel to each other, making it possible to tap into a functional nerve and direct those signals to a non-functional neighbor.
Perfume ads, beer billboards, movie posters: everywhere you look, women's sexualized bodies are on display. A new study published in Psychological Science, a journal of the Association for Psychological Science, finds that both men and women see images of sexy women's bodies as objects, while they see sexy-looking men as people.
Scientists at the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa (uOttawa) have discovered that mice that lack a gene called Snf2l have brains that are 35 per cent larger than normal. The research, led by Dr. David Picketts and published in the prestigious journal Developmental Cell, could lead to new approaches to stimulate brain regeneration and may provide important insight into developmental disorders such as autism and Rett syndrome.
An Indiana University-led research team, along with a group of national and international collaborators, has identified and prioritized a comprehensive group of genes most associated with schizophrenia that together can generate a score indicating whether an individual is at higher or lower risk of developing the disease.
MAYWOOD, Il. -- Following a stroke, factors as varied as blood sugar, body temperature and position in bed can affect patient outcomes, Loyola University Medical Center researchers report.
In a review article in the journal MedLink Neurology, first author Murray Flaster, MD, PhD and colleagues summarize the latest research on caring for ischemic stroke patients. (Most strokes are ischemic, meaning they are caused by blood clots.)
Researchers at the University of Leeds have found a previously unknown mechanism through which pain is signalled by nerve cells – a discovery that could explain the current failings in the drug development process for painkillers and which may offer opportunities for a new approach.
AURORA, Colo. (May 14, 2012) - Why does one person become anorexic and another obese? A study recently published by a University of Colorado School of Medicine researcher shows that reward circuits in the brain are sensitized in anorexic women and desensitized in obese women. The findings also suggest that eating behavior is related to brain dopamine pathways involved in addictions.
Toronto, CANADA – A walk in the park may have psychological benefits for people suffering from depression.
In one of the first studies to examine the effect of nature walks on cognition and mood in people with major depression, researchers in Canada and the U.S. have found promising evidence that a walk in the park may provide some cognitive benefits.
CHAMPAIGN, Ill. — The sound of silence isn't so golden for consumers, and both marketers and advertisers should take note, says new research from a University of Illinois expert in new product development and marketing.
According to published research from Ravi Mehta, a professor of business administration, ambient background noise turns out to be an important factor affecting creative cognition among consumers.
Paediatric brain tumours preserve specific characteristics of the normal cells from which they originate – a previously unknown circumstance with ramifications for how tumour cells respond to treatment. This has been shown by Uppsala researcher Fredrik Swartling together with colleagues in the U.S., Canada and England in a study that was published today in the distinguished journal Cancer Cell.
Every year, 80-90 children in Sweden are afflicted with brain tumours, a serious form of paediatric cancer. Today, three of four children who receive treatment survive.
Banning and criminalising the Muslim face veil tests the very foundations of modern liberal society, warn researchers from Queen Mary, University of London and the University of Sussex.
The paper 'Reasons to Ban? The Anti-Burqa Movement in Western Europe' examines the move to legislate against, and to criminalise face-veiling which has swept across the EU recently.
The European movement against face-veiling is now widespread, with calls to implement a ban, or a ban being in place, in France, Belgium, Italy, Spain, the Netherlands, Scandinavia, and Germany.
