Broken Internal Clock To Offset Those Bad Eating Habits

Timing our meals can fend off diseases caused by bad genes or bad diet. Everything in our body is programmed to run on a 24-hour or circadian timetable that repeats every day. Nearly a dozen different genes work together to produce this 24-hour circadian cycle.

These clocks are present in all of our organs, tissues and even in every cell. These internal clocks tell us when to sleep, eat, be physically active and fight diseases. As long as this internal timing system work well and we obey them, we stay healthy.

Brain Cells In Human Brain Can Be Counted

Researchers at the Universities of Bonn and Tübingen are now one step closer to answering this question. They were able to demonstrate that some brain cells fire mainly for quantities of three, others for quantities of four and others for other quantities.

A similar effect can be observed for digits: In humans, the neurons activated in response to a "2" are for instance not the same as the neurons activated for a "5". The results also demonstrate how we learn to handle number symbols in comparison to quantities. The study is published online in the journal Neuron.

Impact of Gastric Banding vs Metformin on ?-Cell Function in Adults With Impaired Glucose Tolerance

People with prediabetes or new-onset type 2 diabetes who had gastric banding, a type of bariatric surgery for weight loss, had similar stabilization of their disease to those who took metformin alone, according to a study supported by the National Institutes of Health.

The study was published in  Diabetes Care, coinciding with a presentation during the European Association for the Study of Diabetes Annual Meeting in Berlin.

Mental Health Conditions Can Harm More Than Good

The number of people diagnosed with a mental health condition is increasing, globally. Diagnostic labels can act as passports to accessing public services and help create communities of individuals with the same label. But are these reasons enough to justify their continued use? Getting a diagnostic label is no guarantee of getting the right treatment, and it is often associated with worry and stigma.

A Surgeon So Bad It Was Criminal

The pain from the pinched nerve in the back of Jeff Glidewell's neck had become unbearable. Every time he would turn his head a certain way, or drive over bumps in the road, he felt as if jolts of electricity were running through his body.
