A brain circuit that could indicate the risk of developing Alzheimer’s

Late-onset Alzheimer’s disease (LOAD), the one that appears after age 65, is the most common form of this neurodegenerative disease and accounts for more than 90% of cases. The first brain changes associated with the disease may appear years before the first symptoms, but the lack of clear risk markers complicates the application of the appropriate prevention strategies for those that are more vulnerable.

Gay and bisexual men have higher rate of skin cancer

In the largest study of skin cancer rates among gay, lesbian or bisexual individuals, investigators from Brigham and Women’s Hospital report important differences in skin cancer prevalence among sexual minorities. Rates of skin cancer were higher among gay and bisexual men compared to heterosexual men but lower among bisexual women than heterosexual women. These findings, which were possible because of the sexual orientation and gender identity (SOGI) module built into a national system of surveys, have implications for patient education and community outreach initiatives focused on reducing skin cancer risk. They also have implications for the design of future nationwide surveys. Results are published in JAMA Dermatology.

Researchers stimulate areas vital to consciousness in monkeys’ brains—and it wakes them up

One of the central questions in neuroscience is clarifying where in the brain consciousness, which is the ability to experience internal and external sensations, arises. On February 12 in the journal Neuron, researchers report that a specific area in the brain, the central lateral thalamus, appears to play a key role. In monkeys under anesthesia, stimulating this area was enough to wake the animals and elicit normal waking behaviors.
