New imaging method identifies people at risk for Alzheimer's disease
UCLA researchers using innovative brain-scan technology have shown that the abnormal brain protein deposits that define Alzheimer's disease can be detected in mild cognitive impairment — a condition that increases the risk for developing Alzheimer's and affects 15 to 20 million Americans.
Paying attention sets off symphony of cell synchronization
You know the sensation. When something has your full attention you see it vividly. And when you don't pay attention, you're liable to miss something important. Now a new Northwestern University study sheds light on how attention operates.
Pain relief effectiveness down to mind-set?
Research by the Human Pain Research Group at The University of Manchester suggests that people's responses to placebo or "dummy" pain relief varies according to their way of thinking.
Experience sculpts brain circuitry to build resiliency to stress
It's long been known that experiencing control over a stressor immunizes a rat from developing a depression-like syndrome when it later encounters stressors that it can't control. Now, scientists funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health (NIH), have unraveled the workings of the brain circuitry that inoculates against such hard knocks - the circuitry of resilience.
A reason why video games are hard to give up?
Kids and adults stayed glued to video games this holiday season because the fun of playing actually is rooted in fulfilling their basic psychological needs.
Why are danes the world's happiest nation?
Several months ago, Denmark came top in a world map of happiness (the UK ranked 41st out of 178 nations). And for more than 30 years it has ranked first in European satisfaction surveys. So what makes Danes so content?
Less sugary drinks during childhood may cut disease risk
Symptoms of heart disease and diabetes usually seen in adults are increasingly being found in adolescents according to a longitudinal study, which suggests that reducing the intake of sugar-sweetened beverages during childhood may lessen the risk of chronic disease in later life.
'Speechless' and 'mute' help break the silence of the leaves
Researchers have discovered two genes that guide land plants to develop microscopic pores that they can open and close as if each pore was a tiny mouth.
Mind and body in fruit fly
Male fruit flies are smaller and darker than female flies. The hair-like bristles on their forelegs are shorter, thicker. Their sexual equipment, of course, is different, too.
Sleep disturbances, nightmares are common among suicide attempters
In the first known report of its kind, a study published in the January 1st issue of the journal SLEEP finds that sleep disturbances are common among suicide attempters, and that nightmares are associated with suicidality.

How appetite-stimulating brain cells work overtime during fasting
During periods of fasting, brain cells responsible for stimulating the appetite make sure that you stay hungry. Now, a new study of mice reported in the January issue of the journal Cell Metabolism, published by Cell Press, reveals the complex series of molecular events that keep those neurons active.
Study finds surfing safer than soccer
While public perception may frame surfing as a dangerous sport, new research begs to differ. In the first study of its kind, researchers have computed the rate of injury among competitive surfers and found they are less prone to harm than collegiate soccer or basketball players.
What memories are made of?
Why is it that amnesia patients can't remember their names or addresses, but they do remember how to hold a fork? It's because memories come in many flavors, says Fred Helmstetter, professor of psychology at the University of Wisconsin–Milwaukee (UWM). Remembering what is not the same as remembering how.
Repetitive motion speeds nanoparticle uptake
Newly published research by Rice University chemists and North Carolina State University toxicologists finds that repetitive movement can speed the uptake of nanoparticles through the skin.
Feeling tired? You may be less likely to get hurt
Sleepiness and sleep deprivation have long been associated with an increased risk of injury. However, the results of a recent study by a University of Missouri-Columbia researcher suggest that this commonly accepted theory might not be true.
On the golf tee or pitcher's mound, brain dooms motion to inconsistency
If you've ever wondered why your golf swings, fastballs or free throws don't quite turn out the same way each time, even after years of practice, there is now an answer: It's mostly in your head.
Dentists could detect osteoporosis, automatically
Researchers in the School of Dentistry at The University of Manchester have created a unique way of identifying osteoporosis sufferers from ordinary dental x-rays.
Imaging pinpoints brain regions that 'see the future'
Human memory, the ability to recall vivid mental images of past experiences, has been studied extensively for more than a hundred years. But until recently, there's been surprisingly little research into cognitive processes underlying another form of mental time travel — the ability to clearly imagine or "see" oneself participating in a future event.
How many genes does it take to learn?
Scientists analyzing the genomics of a marine snail have gotten an unprecedented look at brain mechanisms, discovering that the neural processes in even a simple sea creature are far from sluggish.
Harnessing fat to attack cancer
Scientists at Duke University Medical Center have harnessed the much maligned fat particle to serve a higher purpose: battling human cancers.
