Defects in the transport of cells' energy organelles are a suspected cause of diseases including Alzheimer's, ALS, Huntington's and Parkinson's. A new study reveals the genetics behind mitochondrial shifts.
intentionally controlled light can help regulate human health and productivity by eliciting various hormonal responses. Tailored LED wavelengths and intensities also can efficiently stimulate plant growth, alter their shapes and increase their nutritional value, opening a new world of scientific and technological possibilities for indoor farming.
A Medical Research Council funded study published today in the journal Science, has found that astrocytes, previously thought of as just supporting neurons in regulating circadian rhythms, can actually lead the tempo of the body's internal clock and have been shown for the first time to be able to control patterns of daily behavior in mammals.
In 2016, Seattle Public Schools pushed back start times for its 18 high schools by 55 minutes. In a paper published Dec. 12 in Science Advances, researchers at the University of Washington and the Salk Institute for Biological Studies announced that, as a result, teens at two Seattle high schools got more sleep on school nights -- a median increase of 34 minutes of sleep each night -- and showed improved attendance and grades.
Although paralysis is the most noticeable result of a spinal cord injury, a new study by researchers at The University of Texas at Austin suggests such injuries could throw off the internal clock of the entire body's daily activities, from hormones to sleep-wake schedules.
The amount of time you sleep, including daytime naps, is linked to your risk of developing cardiovascular disease and death, according to a study of over 116,000 people in seven regions of the world, published in the European Heart Journal.
Moderate damage to the thoracic spinal cord causes widespread disruption to the timing of the body's daily activities, according to a study of male and female rats published in eNeuro. If this also occurs in humans, transitioning patients back to the normal rhythms of their daily life after a spinal cord injury could help prevent further dysregulation of essential biological processes.
In the first ever international review of studies analysing whether being an early riser or a night owl can influence your health, researchers have uncovered a growing body of evidence indicating an increased risk of ill health in people with an evening preference as they have more erratic eating patterns and consume more unhealthy foods. The findings have been reported in Advances in Nutrition today (Friday 30 November)
For most, the time spent staring at screens -- on computers, phones, iPads -- constitutes many hours and can often disrupt sleep. Now, Salk Institute researchers have pinpointed how certain cells in the eye process ambient light and reset our internal clocks, the daily cycles of physiological processes known as the circadian rhythm. When these cells are exposed to artificial light late into the night, our internal clocks can get confused, resulting in a host of health issues.
Social jet lag -- a syndrome related to the mismatch between the body's internal clock and the realities of our daily schedules -- has been tied to obesity and other health problems. Now, researchers reporting in Current Biology on Nov. 15 have found a clever way to measure social jet lag in people all over the country: by analyzing patterns of activity on the social media platform Twitter.
