Only one group of teenagers used marijuana more often after retail sales were legalized in Washington than they did before -- high school seniors who work 11 or more hours per week, according to new research led by a WSU College of Nursing professor.
A team of scientists spent six months co-designing robots with informal caregivers for people with dementia, such as family members. They found that caregivers wanted the robots to fulfill two major roles: support positive moments shared by caregivers and their loved ones; and lessen caregivers' emotional stress by taking on difficult tasks, such as answering repeated questions and restricting unhealthy food.
Taking a high dose of icosapent ethyl -- a pure and stable prescription form of the omega-3 fatty acid known as EPA -- significantly reduces the occurrence of first, subsequent and total ischemic events, including heart attacks, strokes and related deaths, among people at high cardiovascular risk despite already being on statin therapy, according to new research.
As states around the country move to stiffen punishments for animal cruelty, researchers have found a correlation between the types of animal abuse committed and the perpetrator's relationship to an animal and its owner.
Tilt training effectively prevents fainting, according to new research. The program also improved quality of life, reduced the worry and fear about future fainting and enabled patients to return to work.
The study of more than 1,000 patients with severe heart failure not only confirms that the HeartMate 3™, a next-generation LVAD device, markedly reduced the need for re-operations due to pump malfunctions, but also found that it lowered risk of bleeding events and strokes, compared to the HeartMate II™.
How much vitamin D can boost memory, learning and decision-making in older adults, and how much is too much? A unique study found that overweight and obese older women who took more than three times the recommended daily dose of vitamin D showed improvements in memory and learning -- but also had slower reaction times. The researchers hypothesize that slower reaction times may increase the risk of falling among older people.
An interface system that uses augmented reality technology could help individuals with profound motor impairments operate a humanoid robot to feed themselves and perform routine personal care tasks such as scratching an itch and applying skin lotion. The web-based interface displays a 'robot's eye view' of surroundings to help users interact with the world through the machine.
A recent study finds that older adults feel younger when they feel that they have more control over their daily lives, regardless of stress or health concerns. However, stress and health -- not a sense of control -- play a significant role in how old younger adults feel.
People left blind by retinal degeneration have one option: electronic eye implants. Neuroscientists have now developed an alternative: gene therapy that, in tests, restored vision in blind mice. A gene for green opsin delivered via virus gave blind mice enough sight to discern patterns on an iPad at a resolution sufficient for humans to read. Given existing AAV eye therapies already approved, this new therapy could be ready for clinical trials in three years.
Researchers have found, for the first time, that a blood-clotting protein can, unexpectedly, degrade nerves--and how nerve-supporting glial cells, including Schwann cells, provide protection. The findings show that Schwann cells protect nerves by blocking this blood-clotting protein as well as other potentially destructive enzymes released by muscle cells. The work could have implications for diseases as diverse as amyotrophic lateral sclerosis (ALS), multiple sclerosis, Alzheimer's disease or schizophrenia.
Researchers have introduced a framework, 'Responsibility Exchange Theory,' for understanding why thanking and apologizing, as well as bragging and blaming, matter so much, and presents novel experimental studies that reveal the psychology underlying these communications.
Using functional magnetic resonance imaging (fMRI) and a new method of statistical analysis, researchers have discovered the taste center in the human brain by uncovering which parts of the brain distinguish different types of tastes.
Sub-vocalization, the silent, preparatory muscle movements of the face and larynx that result when singers run a song through their heads prior to vocalizing, could be nudging them out of tune, according to researchers. Their recently published study for the first time presents evidence suggesting a relationship among sub-vocalization, auditory imagery and poor pitch singing.
Diet-induced changes in the human bite resulted in new sounds such as 'f' in languages all over the world, a study by an international team led by researchers has shown. The findings contradict the theory that the range of human sounds has remained fixed throughout human history.
Peer approval is the best indicator of the tendency for new college students to drink or smoke according to new research from Michigan State University. This new finding is key to help universities address the problems of underage or binge drinking.
Puberty is much more than just a time of biological overdrive, propelled by sexual maturation. Progress in developmental science has greatly broadened the perspective of this critical maturational milestone.
