A rat study gives new clues about the damage childhood stress can do that leads to PTSD. (Pixabay/Shutterbug75)Rats that were exposed to a highly distressing event as juveniles experienced changes in brain regions responsible for processing emotions and detecting danger, offering new clues about the mechanisms that can lead to post-traumatic stress disorder in humans, following adverse events during childhood.

We're better at identifying happy screams than those of anger or terror. (Pixabay/StartupStockPhotos)Scientists at the University of Zurich have discovered that humans can more efficiently process and categorize screams that evoke positive or nonalarming emotions than those that communicate aggression or fear.

There's new relief for those who get a little queasy from VR adventures. (AP Photo/Martin Meissner)Researchers have developed a vibrating platform that can reduce the effects of cybersickness for some virtual reality users, addressing an increasingly urgent problem as VR becomes more prevalent in education, art, entertainment and communications.

Infant sound processing can affect speech later in life. (AP Photo/Khalil Senosi)Infants who have trouble distinguishing between native and nonnative speech may be more likely to develop speech-language disorders or to face challenges with grammar and vocabulary later in life, according to new research from scientists at Vanderbilt University and the University of Washington.

Machine learning might help stop cyberattacks in future. (AP Photo/Alastair Grant)A novel machine-learning system can quantify the degree of change between multiple data inputs, enabling more accurate anomaly detection that could have wide-ranging applications in fields as varied as biomedicine, autonomous driving and network security.

The way your attention is focused can profoundly affect your hearing. (Leah Hogsten/The Salt Lake Tribune via AP)University of Memphis researchers found that the degree of attention individuals pay to incoming sounds can influence even the earliest stages of brain processing — including those that scientists once thought were completely automatic.

Evidence may have been found that will establish the link between Parkinson's disease and melanoma. (Unsplash/Dirk Schumacher)Researchers at the National Heart, Lung, and Blood Institute have discovered a connection between the problematic molecules that appear in cases of melanoma and Parkinson's disease, providing a clue that could one day inform new treatments for both diseases.

Researchers are breaking down the link between mental illness and violence. (AP Photo/Wilson Ring)University of Zurich researchers have found that the length of time spent in a psychiatric hospital and the age of a first diagnosis were the most significant variables that separate violent and nonviolent people who live with schizophrenia spectrum disorder.

What makes mice hallucinate? And how can we tell if they've done so? (AP Photo/Robert F. Bukaty)
What makes mice hallucinate? And how can we tell if they've done so? (AP Photo/Robert F. Bukaty)Scientists at Cold Spring Harbor Laboratory and Washington University School of Medicine found that mice that had experiences analogous to hallucinations in humans showed higher dopamine responses, reinforcing the theory that the neurotransmitter may play a role in psychotic disorders such as schizophrenia.

Empathy training might reduce recidivism. (AP Photo/Matilde Campodonico)Parole and probation officers who completed a 30-minute empathy exercise experienced a decreased belief that parolees would reoffend, according to a new study by University of California, Berkeley, psychologists, with the parolees under the officers' oversight exhibiting a 13% reduction in recidivism in the 10 months that followed.
