Researchers have discovered why certain people experience dizziness when they hear a particular sound, such as a musical tone. For patients with semicircular canal dehiscence, there is a pathological hole in the bone that the inner ear is encased in, and certain acoustic tones cause the inner ear fluid to pump. As a result, the ear sends an incorrect signal to the brain, causing dizziness and vertigo.
Like with fingerprints, no two people have the same brain anatomy, a study has shown. This uniqueness is the result of a combination of genetic factors and individual life experiences.
Men are willing to purchase more showy, expensive engagement rings when they imagine themselves with an attractive woman rather than a woman with average looks. Appearance also plays a role for women but, in contrast to men, they are more likely to select an expensive ring with a big stone when they are partnered with a less attractive man.
New evidence shows the power of a method aimed at changing the longstanding problem of encouraging patients with chronic diseases to take their medicine faithfully: insurance plans that charge patients less for the medicines that could help them most. Some plans even make some of the medicines free to the patients with certain conditions.
Teenage drivers are eight times more likely to be involved in a collision or near miss during the first three months after getting a driver’s license, compared to the previous three months on a learner’s permit, suggests a new study.
Multivitamins and mineral supplements do not prevent heart attacks, strokes or cardiovascular death. Data pooled from multiple studies show no health benefit of multivitamins.
A study has found that babies introduced to solid foods early, slept longer, woke less frequently at night and suffered fewer serious sleep problems, than those exclusively breastfed.
Cyberbullying may be linked to higher use of social network sites by school children aged 14-17 years, rather than to simply having a social network profile, according to a new study that examined data from several European countries.
For many Americans, highly processed foods are on the menu for breakfast, lunch, and dinner. Even when the raw materials — grains, for example — are high in vitamins and health-promoting phenolic compounds, processing can rob the final product of these nutrients. Scientists reveal what happens to cancer-fighting phenolic acids in corn when it is processed into cornflakes.
A new study shows that updating visual perceptual skills — which humans rely on to recognize what they see, including potential threats, and ignore unimportant background — is an active process with many similarities to the way they stabilize memories.
