Not So Perfect Pitch
Date: Jun-14-2013People who think they have perfect pitch may not be as in tune as they think, according to a new University of Chicago study in which people failed to notice a gradual change in pitch while listening to music. When tested afterward, people with perfect, or absolute pitch, thought notes made out of tune at the end of a song were in tune, while notes that were in tune at the beginning sounded out of tune. About one out of 10,000 people has absolute pitch, which means they can accurately identify a note by hearing it...
Domestic Violence Reported By 1 In 6 Women At Fracture Clinics
Date: Jun-14-2013One in six women arriving at orthopedic fracture clinics have been victims of physical, emotional, or sexual violence at the hands of an intimate partner within the past year, and one in 50 arrive as a direct result of intimate partner violence (IPV), according to the largest multinational study of its kind to date, led by McMaster University researchers. The report has been published on Online First by The Lancet...
Men Responsible For Causing Menopause In Women
Date: Jun-14-2013A team of scientists at McMaster University have discovered that men are responsible for menopause in women. Rama S. Singh, a professor in McMaster's Department of Biology, along with colleagues Jonathan Stone and Richard Morton, have found that menopause is the result of natural selection. The researchers identified that men have always had a preference for younger women when it comes to mating, which means that older women didn't have the need to continue to be fertile - as men avoided mating with them...
Brain-Computer Interfaces Make New Tasks As Simple As Waving A Hand
Date: Jun-14-2013Small electrodes placed on or inside the brain allow patients to interact with computers or control robotic limbs simply by thinking about how to execute those actions. This technology could improve communication and daily life for a person who is paralyzed or has lost the ability to speak from a stroke or neurodegenerative disease. Now, University of Washington researchers have demonstrated that when humans use this technology - called a brain-computer interface - the brain behaves much like it does when completing simple motor skills such as kicking a ball, typing or waving a hand...
Which Women Should Receive Preventive Breast Cancer Drugs?
Date: Jun-14-2013A new study, published in the journal Cancer Discovery, revealed that genetic variations could be a key indicator of which women are likely and which are unlikely to benefit from tamoxifen or raloxifene for breast cancer prevention. James Ingle, M.D., an oncologist at the Mayo Clinic, who was part of the study, said that the findings are important "because we identified genetic factors that could eventually be used to select women who should be offered the drugs for prevention...
Lifestyle Changes Can Help Prevent Cancer In Women But Do They Follow The Recommendations?
Date: Jun-14-2013The lifetime risk for cancer is greater than 1 in 3 for women in the U.S., but most women do not make the lifestyle choices recommended by the American Cancer Society to reduce that risk and prevent cancer. A multifaceted new survey determined how women view diet and exercise in relationship to cancer and whether they believe they are engaging in healthy behaviors, and whether their diet and exercise choices really meet the minimum recommendations. The results are presented in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers...
The Jaw Is Also A Casualty When Bacterium Causes Gum Disease
Date: Jun-14-2013The newly discovered bacterium that causes gum disease delivers a one-two punch by also triggering normally protective proteins in the mouth to actually destroy more bone, a University of Michigan study found. Scientists and oral health care providers have known for decades that bacteria are responsible for periodontitis, or gum disease. Until now, however, they hadn't identified the bacterium...
Breaking The Cycle Of Transmission With Flu Vaccines Aimed At Younger Populations
Date: Jun-14-2013The huge value of vaccinating more children and young adults for influenza is being seriously underestimated, experts say in a new report, while conventional wisdom and historic vaccine programs have concentrated on the elderly and those at higher risk of death and serious complications. A computer modeling analysis was just published in the journal Vaccine, in work supported by the National Institutes of Health. The study suggests that children in school and young adults at work do the vast majority of flu transmission...
Body Clocks Linked To Osteoarthritis
Date: Jun-14-2013Scheduled exercise, regular meals and the periodic warming and cooling of joints could be used to relieve the symptoms of osteoarthritis according to scientists at The University of Manchester. Their research may also help explain why older people are more prone to developing this common joint disorder. The team in the Faculty of Life Sciences has established for the first time that cartilage cells have a functioning body clock that switches on and off genes controlling tissue function...
New Layer Of The Human Cornea Discovered
Date: Jun-14-2013Scientists at The University of Nottingham have discovered a previously undetected layer in the cornea, the clear window at the front of the human eye. The breakthrough, announced in a study published in the academic journal Ophthalmology, could help surgeons to dramatically improve outcomes for patients undergoing corneal grafts and transplants. The new layer has been dubbed the Dua's Layer after the academic Professor Harminder Dua who discovered it...
