Body clock disruptions may be an early sign of Alzheimer's

On January 30, 2018, Posted by , In Buzz, By ,,,,, , With No Comments

New research published in JAMA Neurology suggests that those people whose memory is intact and who do not show any signs of Alzheimer’s can have disrupted circadian rhythms — which may be a very early sign of Alzheimer’s. Napping during the day may disrupt the sleep/wake cycle in seniors. This…

Dopamine neurons may regulate our biological clock

On August 7, 2017, Posted by , In Buzz, By ,,,, , With No Comments

Switching off and going to sleep may be more difficult if we are engaged in a pleasurable activity, suggests new research. Researchers have identified some of the brain cells that control our body’s internal clock. The findings provide new insights into how the human body responds to jet lag, as…

What time we eat affects our biological clock, study finds

On June 2, 2017, Posted by , In Buzz, By ,,,,, , With No Comments

The human body works around the clock. Our biological functions follow 24-hour cycles, or circadian rhythms, which are physiological and mental changes that are driven by our internal biological clocks. New research explains how we can reset one of these body clocks. Having meals at timed intervals could help to…

Vasopressin: Water management and the biological clock

On May 31, 2017, Posted by , In Buzz, By ,,,, , With No Comments

Water is the molecule of life; without it, none of us would be here. However, despite its importance, how the body manages water still holds some secrets. Innovative research in Canada generates new insight. Vasopressin helps us to manage our body’s water, but it is more complicated than we thought….

Controlling the body clock

A new study from the laboratory of Hiroki Ueda at the RIKEN Quantitative Biology Center investigates circadian timekeeping with a novel approach to creating genetic knock-out rescue mice. Published in Molecular Cell, the study shows how this technique was used to quickly create numerous mouse lines, each with different…

Brain's biological clock stimulates thirst before sleep

On September 29, 2016, Posted by , In Buzz, By ,,,,,, , With No Comments

The brain’s biological clock stimulates thirst in the hours before sleep, according to a study published in the journal Nature by McGill University researchers. The finding along with the discovery of the molecular process behind it provides the first insight into how the clock regulates a physiological…

Our biological clock governs neuron reactivity

On June 24, 2016, Posted by , In Buzz, By ,,,, , With No Comments

Researchers from the University of Liège (Belgium), in collaboration with colleagues from Milan (Italy), Surrey (UK) and West Virginia (USA), discovered that controlling neuron reactivity is part of the mechanisms used by our biological clock to maintain cognitive functioning. This finding, published in Nature Communications this week, shows that…

Mapping the circuit of our internal clock

Research sheds light on the neural structure that controls our sleep, eating habits, hormones and more. What’s that old saying about Mussolini? Say what you will but he made the trains run on time. Well, the suprachiasmatic nucleus – SCN for short – makes everything in the body…

Clock gene may connect mood and sleep

If you pull an all-nighter or stay up late to binge watch Game of Thrones, you will probably be grumpy the next day. But if you don’t get enough sleep for weeks or months on end, you may develop depression or other lasting mood problems, and Howard Hughes Medical…

A new molecular alarm clock in vertebrates

On February 17, 2016, Posted by , In Buzz, By ,,, , With No Comments

Dozens of chemical interactions in the vertebrate brain go into maintaining a natural sleep schedule, and scientists have recently found one more player on the field: a neurochemical called neuromedin U, or Nmu. The protein, which was analyzed in zebrafish but is also found in humans, acts to stimulate…
