On Tuesday, February 7, at 7 p.m., Cleveland Park Library in Washington, DC will host Alvaro Fernandez as he discusses The SharpBrains Guide to Brain Fitness: 18 Interviews with Scientists, Practical Advice, and Product Reviews to Keep Your Brain Sharp (book also available via DC library system).
The book expands on the concept of neuroplasticity that recent works such as the New York Times bestseller, The Brain that Changes Itself, and the PBS Brain Fitness Program have introduced to the world. Neuroplasticity, or the t
Changes in testosterone levels occur naturally during sleep, both in men and women. Testosterone levels rise during sleep and decrease during waking hours. Research has shown that the highest levels of testosterone happen during REM sleep, the deep, restorative sleep that occurs mostly late in the nightly sleep cycle. Sleep disorders, including interrupted sleep and lack of sleep reduces the amount of REM sleep, will frequently lead to low testosterone levels. And this is important for men and women.
There’s strong evidence of a relationship between testosterone and sleep disordered breathing, including obstructive sleep apnea. Studies have shown that low testosterone levels frequently occur in men with obstructive sleep apnea.
Men are far different beasts than our women counterparts. Were less likely to visit the doctor and exercise, and yet we suffer from more health problems and we die at a younger age. Were stubborn animals that are made-up of some dramatically different hormones that our environment seems to be hard at work on diminishing .
Men think differently than women. We train different, and we should be eating in a different way. Where the fitness industry spends a lot of time focusing on women, were going to go over 50 facts about .

Researchers at Duke University Medical Center have developed a new way to identify the genes of harmful microbes, particularly those that have been difficult to study in the laboratory.
This new method uses chemicals to create mutant bacteria, followed by genomic sequencing to identify all mutations. By looking for common genes that were mutated in Chlamydia sharing a particular trait, the investigators were able to rapidly “zero in” on the genes responsible for that trait.
The approach is versatile and inexpensive enough that it could be applied to study a range of microorganisms, said Raphael Valdivia, PhD, an associate professor of molecular genetics and microbiology at Duke.
“We were able to learn about genes that allow Chlamydia to flourish in their hosts without the traditional, lengthy process of domesticating the pathogen to accept recombinant DNA,” Valdivia said.
“Our approach marries classical microbiology techniques with 21st century genome-sequencing technologies.
