Second Life or same life? Bullying continues online

It happens in school, at work, physically, verbally, even by email and text — now researchers at The University of Nottingham say there’s no escape in the virtual world.

Researchers are examining the worrying appearance of bullying in the virtual world. Citizens (avatars) of Second Life say targets are likely to be individuals who are new to the virtual world.

Adult stem cell treatment restores motor function in paralyzed rats

Rats paralyzed due to loss of blood flow to the spine returned to near normal ambulatory function six weeks after receiving grafts of human spinal stem cells (hSSCs), researchers from the University of California, San Diego (UCSD) School of Medicine report.

Why does Menthol feel 'fresh'?

Scientists have identified the receptor in cells of the peripheral nervous system that is most responsible for the body's ability to sense cold.

The findings reveal one of the key mechanisms by which the body detects temperature sensation. But in so doing it also illuminates a mechanism that mediates how the body experiences intense stimuli – temperature, in this case – that can cause pain.Menthol and TRPM8

Brain pacemakers can regulate signals - and erase bad ones

You might think it's something from the movie "Total Recall" but instead researchers are using brain "pacemakers" to regulate diseased signals in the brains of Parkinson's disease patients.

These devices are FDA-approved and in use in 30,000 patients but still not well understood.

Magnificent moms - Mule Deer rescue fawns, even from other species

Mule deer are giving new meaning to watching out for other mothers' kids. Whitetail deer, not so much.

Urea cycle disorder treatment 80 percent effective after 25 years

The simple notion of copying the body’s own natural "waste disposal" chemistry to mop up potentially toxic nitrogen has saved an estimated 80 percent of patients with urea cycle disorders --- most of them children – according to a report in this week’s New England Journal of Medicine summarizing a quarter century of experience with the treatment.

Doing math without being taught arithmetic

Children are able to solve approximate addition or subtraction problems involving large numbers even before they have been taught arithmetic, according to a study conducted at Harvard University, by researchers from the University of Nottingham and Harvard.

Toward a living memory chip

A new experiment has shown that it's possible to store multiple rudimentary memories in an artificial culture of live neurons. The ability to record information in a manmade network of neurons is a step toward a cyborg-like integration of living material into memory chips. The advance also may help neurologists to understand how our brains learn and store information.

Help your child form relationships by buying them a robot

A project which is using robots to help children with developmental or cognitive impairments to interact more effectively has just started at the University of Hertfordshire.

Epicatechin and exercise boosts memory in mice

A natural compound found in blueberries, tea, grapes, and cocoa enhances memory in mice, according to newly published research. This effect increased further when mice also exercised regularly.

"This finding is an important advance because it identifies a single natural chemical with memory-enhancing effects, suggesting that it may be possible to optimize brain function by combining exercise and dietary supplementation," says Mark Mattson, PhD, at the National Institute on Aging.

How cells breathe

Inhaling oxygen is only the first step in a long journey through the nooks and crannies of the body. The oxygen is then transported via the blood to all cells in the body. The same goes for nourishment from food we eat. Inside the cell, the oxygen and nourishment are transformed into energy and carbon dioxide, which we breathe out. In a new dissertation from Stockholm University in Sweden, Kristina Faxén has mapped how so-called cell breathing takes place.

Brain activity reflects differences in types of anxiety

All anxiety is not created equal, and a research team at the University of Illinois now has the data to prove it. The team has found compelling evidence that differing patterns of brain activity are associated with each of two types of anxiety: anxious apprehension (verbal rumination, worry) and anxious arousal (intense fear, panic, or both).

UCL scientist develops a 'distraction indicator'

A scientific indicator of how easily distracted you are has been designed by a University College London psychologist. It could be used as another assessment tool during the recruitment process and would have particular benefits in fields where employee distraction could lead to fatal errors.

Researchers Find Deadly Prescription Drug Effects Six Years Before FDA

Northwestern University's Charles Bennett, M.D., is a super sleuth of potentially deadly prescription drug reactions. He leads a national SWAT team of doctors called RADAR (Research on Adverse Drug Events and Reports) based out of Northwestern's Feinberg School of Medicine. They swoop in to investigate early signs of trouble years before the Food and Drug Administration (FDA) takes notice.

'Smart' mice teach scientists about learning process

Mice genetically engineered to lack a single enzyme in their brains are more adept at learning than their normal cousins, and are quicker to figure out that their environment has changed, a team led by researchers at UT Southwestern Medical Center has found.

The results, appearing today in the online edition of the journal Nature Neuroscience, reveal a new mechanism of learning in the brain, which might serve in humans as a target for treating disorders such as post-traumatic stress disorder, Alzheimer’s disease or drug addiction, the researchers said.
