Research: Gene Governing Body's Biological Clock Acts Differently in Males Versus Females

Research suggests that a gene that governs the body's biological (circadian) clock acts differently in evils versus females and may protect females from heart disease. The study is the first to analyze circadian blood pressure rhythms in female mice. The research, published ahead of print in the  American Journal of Physiology – Regulatory, Integrative and Comparative Physiology , was chosen as an APS select  article. 

Study: Ketogenic Supplementation Reduce Seizures Without Dietary Restriction

The ketogenic diet has proven successful in helping people lose weight and improve their overall health, including those with epilepsy. The low-carb diet transitions the body from burning sugar to burning fat and ketones for energy. New research suggests that increasing blood ketones by using ketogenic supplementation can reduce seizures without dietary restriction.

Aging worms: More Insights on Living a Stronger and Longer Life

Research from the University of Michigan Life Sciences Institute has uncovered a cause of declining motor function and increased frailty in tiny aging worms—and a way to slow it down.  The findings, scheduled to publish in Science Advances, identify a molecule that can be targeted to improve motor function and indicate that similar pathways may be at play in aging mammals as well.

Evolution of Metabolism: Fruit Flies Help to Shed Light

Researchers have discovered that the ability to use sugar as food varies strongly related closely related to fruit fly species. They have also identified the genetic basis of this variation. In the future, it will be interesting to explore whether human populations with different dietary histories may respond differently to modern diets rich in sugars.

Animal Study: Exercise Can Boost Metabolism

A new study shows neurons in mice that influence metabolism are active for up to two days after a single workout. The  study , published in the journal  Molecular Metabolism , offers new insight into the brain's potential role in fitness and may provide a target for developing therapies that improve metabolism.

Gene Vital to Circadian Rhythms: New Study

Circadian rhythms (from the Latin circa diem – "around a day") based on the Earth's 24-hour rotation have been observed since the fourth century. But it's only recently that scientists have come to understand the fundamental role of circadian rhythms in everything from body temperature to reproduction to metabolism.

Disruptions of our internal clocks are implicated in many health issues, including sleep and affective disorders, cardiovascular disease, and certain types of cancer, to the tune of billions of dollars in health care costs.
