Why You Should Never, Ever Pull An All-Nighter
It's pretty straight forward: Sleep deprivation is really bad for you.
But even if you don't pull all-nighters, chronically getting too little sleep can be dangerous. For example, drowsiness behind the wheel can be just as deadly as driving under the influence. Over time, in serious cases, sleep deprivation can result in heart disease, stroke and diabetes. And in the immediate aftermath, going without sleep can lead to lack of focus and brain fog, stress and irritability.
But what happens after just one night of no sleep? Watch the Ted-Ed video above to learn about an experiment a high schoo...

7 Keys To A Happy, Healthy Brain
Why are some people sharp as a tack at 95 years old, while others begin struggling with mental clarity in their 50s?
A lot of it has to do with genetics, but certain lifestyle factors also play an important role in how our brain ages. So while you can't control your genes, you can take advantage of the latest science to keep your grey cells strong:
Get your olive oil
Foods high in sugar, unhealthy fats and processed foods -- i.e., the typical American diet -- can wreak havoc on your brain over time. Studies have shown that excess sugar consumption can impair learning and memory, and increase your vulnerability to neurod...

Fruit Flies Fall Into Coma to Survive Three Day Drowning
How much is there to learn about the behavior of a fruit fly? Fruit flies have been used in basic research for more than 100 years. Among the more common reasons for studying a fly including small size, homologous disease genes, and genetic tractability, what we are most interested in their ability to withstand stressful conditions significantly better than a mammal. A key feature of fly survival is their ability to survive a slew of environmental conditions from freezing rain to extensive droughts that occur in the fly's natural environment. In humans, short periods of anoxic stress or oxygen deprivation whether caused by...

Hacking The Nervous System
(Photo: © Job Boot)
One nerve connects your vital organs, sensing and shaping your health. If we learn to control it, the future of medicine will be electric.When Maria Vrind, a former gymnast from Volendam in the Netherlands, found that the only way she could put her socks on in the morning was to lie on her back with her feet in the air, she had to accept that things had reached a crisis point. “I had become so stiff I couldn’t stand up,” she says. “It was a great shock because I’m such an active person.”It was 1993. Vrind was in her late 40s and working two jobs, athletics coach and a carer for disabled ...

Inflammatory Claims About Inflammation
We all appreciate the elegance of simple solutions to complex problems. But we know too that simplicity can often masquerade as truth, hiding a more nuanced reality. Such is the case with inflammation, where pseudoscience, exaggerated claims, false promises, and dangerous oversimplification have dominated for too long. Here is a typical missive:
"Inflammation controls our lives. Have you or a loved one dealt with pain, obesity, ADD/ADHD, peripheral neuropathy, diabetes, heart disease, stroke, migraines, thyroid issues, dental issues, or cancer? If you answered yes to any of these disorders you are dealing with inflammatio...

A Hidden Danger In The New Versions Of Birth Control Pills
Women who take a newer version of birth control pills have a doubled risk of developing potentially fatal blood clots, according to a new study published in the British medical journal BMJ.
Venous thromboembolism is a serious condition that encompasses both deep vein thrombosis -- when a person develops a blood clot in the legs -- and pulmonary embolism, in which the clot travels to the lungs and obstructs breathing. VTE is potentially fatal, and the study indicates that women who take combined oral contraceptives with newer progesterone formulations are two times more likely to develop it as opposed to women who take a ...

The 8 Most Important Things We've Learned About Happiness In The Past 10 Years
We're living in a golden age of happiness -- the scientific study of happiness, at least.
The field of positive psychology has exploded in growth since its inception in 1998, dramatically increasing our understanding of human flourishing. We now know more than ever about what makes us happy, how we can spread happiness socially and geographically, and how happiness affects our physical and mental health.
But it's just the beginning. In the next decade, we're likely to see not only a greater understanding of positive emotions, but also the application of this research on a practical level to improve well-being on a globa...

John Glenn Says Evolution Should Be Taught In Schools
COLUMBUS, Ohio (AP) — John Glenn, who declared as a 77-year-old in a news conference from space that "to look out at this kind of creation out here and not believe in God is to me impossible," says facts about scientific discovery should be taught in schools — and that includes evolution.
The astronaut, now 93 with fading eyesight and hearing, told The Associated Press in a recent interview that he sees no contradiction between believing in God and believing in evolution.
"I don't see that I'm any less religious by the fact that I can appreciate the fact that science just records that we change with evolution and tim...

Work Wellness Programs May Soon Include Genetic Testing
Your employer may one day help determine if your genes are why your jeans have become too snug.
Big companies are considering blending genetic testing with coaching on nutrition and exercise to help workers lose weight and improve their health before serious conditions like diabetes or heart disease develop. It's a step beyond the typical corporate wellness programs that many companies are using to make workers more aware of their risk factors and improve their health. Genetic testing in corporate wellness programs also is relatively uncharted territory. Many employers and insurers cover these tests and counseling for med...

Immediately After A Stroke, Your Next Steps Are Crucial
By Shereen Lehman (Reuters Health) - Time is critical when someone has a stroke, but care can be delayed when victims, bystanders or even health workers don't recognize the emergency, a new study in the UK finds. Better public awareness of the signs of stroke and the importance of seeking immediate emergency care are needed, the authors say. Stroke signs include the sudden onset of various symptoms such as confusion, difficulty speaking, droopy face or slurred speech, weakness in a limb, numbness, being off-balance, visual loss or a really severe headache. "Getting to hospital quickly is...

Death by a Thousand Cuts
It is likely that you don't realize what your state and our nation have lost in economic terms and research productivity as a result of recent cuts in the federal budget and budget instability brought on by a failure of Congress to pass a budget in a timely manner. Although some members of Congress strongly support increased funding for U.S. research, others argue that the time has come for the cost of basic biomedical research to be borne by industry and philanthropy. Those who make that argument either ignore, or are unaware, that this experiment has already been tried -- unsuccessfully.
Nearly 80 years ago, Louisiana ...

With the right rehabilitation, paralyzed rats learn to grip again
After a large stroke, motor skills barely improve, even with rehabilitation. An experiment conducted on rats demonstrates that a course of therapy combining the stimulation of nerve fiber growth with drugs and motor training can be successful. The key, however, is the correct sequence: Paralyzed animals only make an almost complete recovery if the training is delayed until after the growth promoting drugs have been administered.

Poor cardiovascular health linked to memory, learning deficits
People with poor cardiovascular health have a substantially higher incidence of cognitive impairment. Better cardiovascular health was more common in men and among people with higher education and higher income. The incidence of mental impairment was found more commonly in those with a lower income, who lived in the 'stroke belt' or had cardiovascular disease.

MRI reveals genetic activity: Deciphering genes' roles in learning and memory
Doctors commonly use magnetic resonance imaging (MRI) to diagnose tumors, damage from stroke, and many other medical conditions. Neuroscientists also rely on it as a research tool for identifying parts of the brain that carry out different cognitive functions. Now, biological engineers are trying to adapt MRI to a much smaller scale, allowing researchers to visualize gene activity inside the brains of living animals.
