Rejecting unsuitable romantic partners is easy in hypothetical situations, but not so when considering a face-to-face proposition, a new study shows. “When actually faced with a potential date, we don't like to reject a person and make them feel bad, which is not necessarily something that people anticipate when they imagine making these choices,” says the study’s lead researcher.
An intervention that uses music and games to help preschoolers learn self-regulation skills is helping prepare at-risk children for kindergarten, a new study shows. Self-regulation skills -- the skills that help children pay attention, follow directions, stay on task and persist through difficulty -- are critical to a child's success in kindergarten and beyond, said a co-author of the new study.
Don't get along with your boss? Your job performance may actually improve if the two of you can come to grips with the poor relationship. "Seeing eye-to-eye about the employee-supervisor relationship is equally, if not more important than the actual quality of the relationship," said the lead investigator on the study.
Researchers are trying to help patients who have suffered a stroke to improve arm movement by stimulating the brain using a device called a Transcranial Magnetic Stimulator (TMS). The idea is that when one side of the brain is damaged by a stroke, the healthy side tends to generate much more activity to compensate, but that may actually prevent the injured side from recovering, explains the principal investigator.
Medical researchers are considering the possibilities for personalized vaccines in all types of cancer. The first vaccine will be prepared from a warehouse of 72 targets previously identified by the researchers as relevant for treatment in glioblastoma.
For the first time, researchers have transplanted bone marrow stem cells into damaged brain tissue while applying lipoic acid (a potent antioxidant), with the aim of improving neuroregeneration in the tissue. This new way of repairing brain damage, which combines cellular treatment with drug therapy, has shown positive results, especially in forming blood vessels (a process called angiogenesis) in damaged areas of the brains of adult laboratory mice.
Novel robotic walker helps patients regain natural gait and increases productivity of physiotherapists
Survivors of stroke or other neurological conditions such as spinal cord injuries, traumatic brain injuries and Parkinson’s disease often struggle with mobility. To regain their motor functions, these patients are required to undergo physical therapy sessions. A team of researchers has invented a novel robotic walker that helps patients carry out therapy sessions to regain their leg movements and natural gait. The system also increases productivity of physiotherapists and improves the quality of rehabilitation sessions.
Activated through permanent stress, immune cells will have a damaging effect on and cause changes to the brain. This may result in mental disorders. Medical researchers are studying the effects of permanent stress on the immune system.
Current efforts to prevent violence against women and girls are inadequate, according to a new Series published in The Lancet. Estimates suggest that globally, 1 in 3 women has experienced either physical or sexual violence from their partner, and that 7 percent of women will experience sexual assault by a non-partner at some point in their lives.
Employees at small, locally owned businesses have the highest level of loyalty to their employers — and for rural workers, size and ownership of the company figure even more into their commitment than job satisfaction, a new study finds.
In many firms sales people spend as much time negotiating internally for lower prices as they do interacting with customers. A new study finds that firms should allow their sales people to 'waste' energy on internal negotiations. In fact, it says, firms should make the process wasteful on purpose.
Researchers have used a model inspired by patterns of epidemic disease spreading to map how misfolded proteins propagate within the brain.
As real as that daydream may seem, its path through your brain runs opposite reality. Aiming to discern discrete neural circuits, researchers have tracked electrical activity in the brains of people who alternately imagined scenes or watched videos.
Researchers have discovered a link between prenatal enamel growth rates in teeth and weaning in human babies. The research found that incisor teeth grow quickly in the early stages of the second trimester of a baby's development, while molars grow at a slower rate in the third trimester. This is so incisors are ready to erupt after birth, at approximately six months of age, when a baby makes the transition from breast-feeding to weaning.
As we age, we have an increasingly harder time ignoring distractions. But new research reveals that by learning to make discriminations of a sound amidst progressively more disruptive distractions, we can diminish our distractibility. A similar strategy might also help children with attention deficits or individuals with other mental challenges.
The cerebral cortex lacks the ability to replace neurons that die as a result of Alzheimer's, stroke, and other devastating diseases. A new study shows that a Sox2 protein, alone or in combination with another protein, Ascl1, can cause nonneuronal cells, called NG2 glia, to turn into neurons in the injured cerebral cortex of adult mice. The findings reveal that NG2 glia represent a promising target for neuronal cell replacement strategies to treat brain injury.
In contrast to the lay stereotype, dominant people prove to be avid social learners, just like dominant individuals in the animal kingdom. Neuroscientists show this with a complex decision-making task. They offer a more subtle perspective on the lay view wherein dominant individuals ignore others' views and advice.
The higher your level of education, the greater your earnings and your sense of “personal mastery” or being in control of your fate, researchers say. But wait: there’s a downside. A new study confirms that well-educated people are also more likely to encounter overwork, job pressure, and work-to-family conflict. And, in turn, each of these stressors actually undermines mastery.
Disruptions in child care negatively affect children's social development as early as age 4. However, the study also shows that the effects of child care instability are not unduly large -- and some types of instability appear to have no negative impact on children.
The limited coverage that American female athletes get in the media is one of many subtle forms of gender biases they have to cope with. The little exposure they do get often focuses more on their attire, or how attractive, sexy or ladylike they are than on their actual athletic prowess. In the long run, this influences their performance in sports. So say the authors of a new review.
