The authors’ findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth. University of Georgia Professor Ying Xu and his colleagues analyzed information from microarray chips, which are small glass slides containing large amounts of gene material, and have found that low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers.

Poor Sleep May Spur College Weight Gain.
By JAN HOFFMAN / OCTOBER 26, 2015 12:39 PM Credit: Juliette Borda As the first semester of the school year reaches the halfway mark, countless college freshmen are becoming aware that their clothes are feeling rather snug.

Now new research suggests that an underlying cause for the weight gain may be the students’ widely vacillating patterns of sleep. A study in the journal Behavioral Sleep Medicine looked at the sleep habits of first-semester freshmen. …

I dozed and drifted onto the gravel shoulder toward a drop-off onto someone’s lawn. The bang of my right side mirror striking a mailbox woke me up. I swerved left and skidded back into the road. Safe this time, but frightened.” Dan was often sleepy during the day. He decided to see his doctor and told him about his near miss and some other things that had been happening lately. He fell asleep at night the moment he …

A daylight saving switch survival guide.
Tom Avril, Inquirer Staff Writer Posted: Friday, October 30, 2015, 4:30 AM It is dark when the alarm goes off. It remains dark well past that first cup of coffee. Fear not, sleepyhead, for help is on the way Sunday – in the form of that annual mass reprogramming of digital devices that comes with the end of daylight saving time. But coping with the shift requires more than just turning clocks back by an hour, sleep medicine specialists warn. Many people will feel off their game for a day or two, and those with existing sleep issues can take …

In an ideal world, you’d master all three. But, yeah, life happens. So where should you start? Exercising, eating well and getting plenty of sleep are all crucial to shedding pounds, but one might stand out from the crowd. By K. Aleisha Fetters Oct. 16, 2015 | 9:00 a.m. EDT For the past few decades, the question has been, “What’s more important for weight loss: exercise or healthy eating?” And, for decades, we have cut calories, fat and carbs, and spent more money on gym memberships than our parents would have ever imagined.

Young drivers don’t see dangers of driving tired
Driving drowsy is just as dangerous as driving drunk. Drivers are more likely to get behind the wheel drowsy than drunk despite it being just as dangerous, and the worst offenders are those under 30, a QUT study has found. The research undertaken by QUT’s Centre for Accident Research & Road Safety – Queensland (CARRS-Q) will be presented today at the 2015 Australasian Road Safety Conference on the Gold Coast, which runs until October 16. Road safety researcher Chris Watling said driving sleepy and driving drunk were two risky behaviours linked to a comparable increase in crash risk, yet drivers …
For Our Returning Troops, Post-Traumatic Sleep Disorders Are the New PTSD
Published on October 22, 2015 Sleep deprivation during military deployment is archaic, harmful, and institutionally unavoidable. It may aggravate, and even cause, PTSD in veterans returning from combat, reports Van Winkle’s. The root of veterans’ chronic insomnia, and the PTSD that often develops alongside it, isn’t a disorder that can be cured as part of their post-discharge adjustment. It’s a symptom of larger problems that begin during deployment itself. The military indoctrinates healthy American adults into a “culture of sleep deprivation” that persists throughout their careers, says Shattuck, who works at the Naval Postgraduate Center in Monterrey, California. She says …

Sleep Deprivation Affects Stem Cells, Reducing Transplant Efficiency, Study Finds
Published on October 15, 2015 According to Medical Xpress, a sleep deficit of just 4 hours can effect stem cells of the blood and immune system and reduce the efficiency of transplants. Drowsy mice make poor stem cell donors, according to a new study by researchers at the Stanford University School of Medicine. A sleep deficit of just four hours affects by as much as 50 percent the ability of stem cells of the blood and immune system to migrate to the proper spots in the bone marrow of recipient mice and churn out the cell types necessary to reconstitute …
