Study at Berkeley Lab’s Advanced Light Source Links Vitamin D Deficiency to Accelerated Aging of Bones
Everyone knows that as we grow older our bones become more fragile. Now a team of U.S. and German scientists led by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley has shown that this bone-aging process can be significantly accelerated through deficiency of vitamin D – the sunshine vitamin.(more…)
Controversy exists over what some mental health experts call “hypersexuality,” or sexual “addiction.” Namely, is it a mental disorder at all, or something else? It failed to make the cut in the recently updated Diagnostic and Statistical Manual of Mental Disorders, or DSM-5, considered the bible for diagnosing mental disorders. Yet sex addiction has been blamed for ruining relationships, lives and careers.
Now, for the first time, UCLA researchers have measured how the brain behaves in so-called hypersexual people who have problems regulating their viewing of sexual images. The study found that the brain response of these individuals to sexual images was not related in any way to the severity of their hypersexuality but was instead tied only to their level of sexual desire.

UCLA-led study shows that many countries have it, but not the U.S.
Uruguay has it. So does Latvia, and Senegal. In fact, more than half of the world’s countries have some degree of a guaranteed, specific right to public health and medical care for their citizens written into their national constitutions.
The United States is one of 86 countries whose constitutions do not guarantee their citizens any kind of health protection. That’s the finding of a new study from the UCLA Fielding School of Public Health that examined the level and scope of constitutional protection of specific rights to public health and medical care, as well as the broad right to health.

Asian Indians are one of the fastest growing ethnic groups in the United States, and roughly half a million people of Indian ancestry live in California — more than any other state. Individuals from this group are strongly predisposed to obesity-related conditions such as diabetes and heart disease, due in large part to physical inactivity, diets low in fruit and vegetables, and insulin resistance.

A team of researchers at the IRCM, led by Dr. Javier M. Di Noia in the Immunity and Viral Infections research division, discovered a novel research model for the study of auto-immune diseases. The Montréal scientists are the first to find a way to separate two important mechanisms that improve the quality of antibodies. This study was featured in a recent issue of The Journal of Immunology.(more…)
Low vitamin D blood levels are linked to greater risk of heart disease in whites and Chinese, but not in blacks and Hispanics, according to a study appearing this week in JAMA, the Journal of the American Medical Association.
Growing evidence has suggested that low blood levels of 25-hydroxyvitamin are associated with higher risk of developing coronary heart disease among whites. Few of these studies included substantial numbers of people from other races. (more…)
In a year’s time, the 3-D printers at Yale’s Center for Engineering Innovation and Design (CEID) have churned out countless parts, prototypes, and curiosity-driven experiments in plastic — rotorheads and racecar uprights, cardiac pump pieces and thermostats, snowmen, keychains, and fantastical geometric shapes.(more…)
A study led by researchers from Lawrence Berkeley National Laboratory has found for the first time that thirdhand smoke—the noxious residue that clings to virtually all surfaces long after the secondhand smoke from a cigarette has cleared out—causes significant genetic damage in human cells.(more…)
