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.

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.
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.
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.
An 8-week program of mindfulness training to enhance self-management among people with chronic illnesses such as diabetes and arthritis, a study has found. The researchers used rates of initiation of health behavior action plans to measure improvement in the patients' self-management skills.
Increasing evidence suggests that being an individual type of risk of developing type 2 diabetes and cardiovascular disease, likely through a combination of poor diet, erratic eating patterns, and irregular sleeping hours, say European researchers.
What can seashells, lightning and the coastline of Britain teach us about new drugs for cancer? The answer, according to a team of researchers at the USC Viterbi School of Engineering, may revolve around fractals, the infinitely complex patterns found in nature.
Researchers applied a machine learning technique that could potentially translate patterns of activity in fear-processing brain regions into scores on questionnaires used to assess a patient's fear of pain. This neuroscientific approach may help reconcile self-reported emotions and their neural underpinnings.
Negative mood—such as sadness and anger—is associated with higher levels of inflammation and may be a signal of poor health, according to researchers at Penn State.
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.
The amount and composition of milk produced by dairy cows appears to be more regulated by internal, annual biological rhythms than by environmental factors such as heat and humidity, according to researchers who studied more than a decade of production records from herds across the country.
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.
