Think boys mature faster than girls? Or vice versa? Let's go to the MRI!
Researchers at Oregon Health&Science University and Washington University in St. Louis say they can now accurately predict a young person's age simply by taking an MRI brain scan and analyzing it with a numerical model.
Since man has been able to think about big issues, such as why we are the way we are, it has been known that what happens during the daytime, including emotional stress and physical activity, can affect sleep. When an animal is active and awake, research shows, regulatory substances also build up in the brain that induce sleep.
But what in wakefulness is driving these sleep regulatory substances? Sleep disorders affect between 50 and 70 million Americans, according to the Institute of Medicine of the National Academies. The Institute also estimates the lost productivity and mishaps of fatigue cost businesses roughly $150 billion, while motor vehicle accidents involving tired drivers cost at least $48 billion a year.
Multitasking is a part of everyday home life but increasingly a part of the workplace as well - as in anything, not all people will be suited to it. How workers feel about multitasking and how they have adapted to it (or will) may influence their job satisfaction and the likelihood of quitting, an important factor in hiring decisions.
Soybean cookies sound pretty disgusting, right? Soybeans and soybean oil were among the many approaches to healthier unhealthy food once it was discovered that saturated fats, which can be found in foods such as cream, cheese and butter, were bad for the heart.
But soybean oil spoiled when heated so producers had to hydrogenate the oil to keep it stable, thus creating trans fats. Guess what turned out to also be bad for you?
Can playing "Call of Duty 2" improve your brain power? University of Rochester researchers say that, and other action video games, train people to make the right decisions faster. Video games help players develop a heightened sensitivity to what is going on around them and that improves a wide variety of general skills that can help with everyday activities like driving, reading small print, keeping track of friends in a crowd, and even navigating around town. Bring on "Halo:Reach" then!
If you are a man aged 55 to 74 years with low baseline blood levels of prostate specific antigen (PSA), you don't need further screening, says a new study in Cancer. Aggressive investigation was instead associated with a large increase in cumulative incidence and potential overtreatment for men from 1993 to 1999.
Prostate cancer is the most commonly diagnosed malignancy and the third leading cause of death from cancer in men in Western countries. While a man in the United State has about a one in six chance of being diagnosed with prostate cancer during his lifetime, his risk of dying from the disease is relatively low, about one in 36.
