A new study has found that about 40 percent of adults in the United States who drink alcohol do so in amounts that risk health consequences, and identifies a range of factors associated with starting or stopping drinking too much.
Professional baseball players who score higher on a test of hand-eye coordination have better batting performance -- particularly in drawing walks and other measures of 'plate discipline,' reports a study.
Research reveals that the scent of coffee alone may help people perform better on the analytical portion of the Graduate Management Aptitude Test, or GMAT, a computer adaptive test required by many business schools.
A deep analysis of a series of surveys across 16 countries that spanned several years shows that people who are on the conservative end of the political spectrum believe their lives are meaningful while those on the liberal end continue to search for meaning.
Teens who spend lots of time using digital devices are prone to psychiatric problems, reports a team of scientists in a new study. Children who are heavy users of digital devices are twice as likely as infrequent users to show symptoms of attention-deficit/hyperactivity disorder (ADHD), the study finds.
A new study found that young adults who had a parent incarcerated during their childhood are more likely to skip needed healthcare, smoke cigarettes, engage in risky sexual behaviors, and abuse alcohol, prescription and illicit drugs. These findings have a potentially broad impact, as more than five million US children have had a parent in jail or prison.
A new, highly accurate MRI technique can monitor iron levels in the brains of multiple sclerosis (MS) patients and help identify those at a higher risk for developing physical disability, according to a new study.
In a new study in mice, researchers have identified a key protein involved in the irregular brain cell activity seen in autism spectrum disorders and epilepsy. The protein, p53, is well-known in cancer biology as a tumor suppressor.
The consequences of climate change are immense, and believed by many experts to be largely irreversible (and exponential), causing threats coming from heat waves, flooding, declines in agriculture, and decreasing biodiversity, to name a few. Given that climate change, at least in part, is rooted in human behavior, an obvious question to ask is: Can psychological science offer evidence-based solutions to climate change?
New research on how cannabis use alters eating behavior could lead to treatments for appetite loss in chronic illness, according to experts. Using a new procedure to dose lab rats with cannabis vapor, the researchers found how the drug triggers hunger hormones. They also identified specific brain regions that shift to 'hungry' mode while under the influence.
Hormones that signal the body's state of hunger and fullness could be the key to new treatments for drug and alcohol addiction. Gut hormones have received considerable attention from scientists seeking to understand overeating and obesity, which led the panelists to discover that those hormones are also involved in addiction.
Scientists have discovered that a small group of brain cells in the hypothalamus called 'orexin' neurons could be a promising target for medications for controlling binge eating episodes in individuals with obesity. These neurons, named for the chemical messenger they use to communicate with other brain cells, have previously been shown to be important for addiction to several drugs, including cocaine.
A simple instruction to change your thinking as mealtime approaches can help cut calories, according to new research. By encouraging study participants to concentrate on different types of information when planning their meal, the experimenters saw portion sizes shift. Adopting a health-focused mindset produced better outcomes than focusing on pleasure or the desire to fill up.
An analysis of information gathered for an ongoing and federally sponsored study of aging and disability adds to evidence that a substantial majority of older adults with probable dementia in the United States have never been professionally diagnosed or are unaware they have been.
Scientists examined positions to detect motor and target errors and whether error signals from these positions were used for learning, finding that the parietal lobe detected causes of motor errors in arm reaching and provided signals to compensate for errors. They also revealed that Brodmann area 5 detected the self-generated motor error and that Brodmann area 7 detected target error caused by target movements, both providing error signals for adaptation.
Children with autism have structural and functional abnormalities in the brain circuit that normally makes social interaction feel rewarding, according to a new study from the Stanford University School of Medicine.
