Slumber party: reptiles, like us, have REM sleep and may dream

By Will Dunham WASHINGTON (Reuters) - Research in a German laboratory involving five lizards called Australian bearded dragons indicates that these reptiles may dream and could prompt a fundamental reassessment of the evolution of sleep. Scientists said on Thursday they have documented for the first time that reptiles, like people, experience rapid eye movement, or REM, sleep and another sleep stage called slow-wave sleep. Because REM sleep is when dreaming occurs in people, the findings suggest that these lizards dream, too.

Do Australian Dragons Dream? Sleep Discovery Surprises Scientists

Maybe, according to new research that finds rapid eye movement (REM) and slow-wave sleep in a lizard, the Australian dragon, for the first time. REM sleep is characterized by brain waves that look similar to waking brain activity. In mammals, the large muscles of the body are immobile, but the eyes twitch randomly during REM sleep.

Repairs to keep ULA rocket grounded until summer, company says

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - United Launch Alliance's workhorse Atlas 5 rocket will remain grounded until this summer while engineers fix a problem that triggered an early engine shutdown during its last flight, the space venture said on Friday. The Atlas 5 rocket that blasted off from Florida's Cape Canaveral Air Force Station on March 22 successfully delivered an Orbital ATK cargo ship to the International Space Station for NASA. United Launch Alliance, or ULA, is a partnership of Lockheed Martin Corp. and Boeing Co.. Engineers have traced the problem to a fuel control valve in the RD-180 engine that reduced the amount of kerosene delivered during the boost phase of the flight, ULA said in a statement.

China aims for manned moon landing by 2036

China wants to put astronauts on the moon by 2036, a senior space official said, the latest goal in China's ambitious lunar exploration program. China in 2003 became the third country to put a man in space with its own rocket after the former Soviet Union and the United States. It has touted its plans for moon exploration and in late 2013 completed the first lunar "soft landing" since 1976 with the Chang'e-3 craft and its Jade Rabbit rover.

Did Opioids Kill Prince? Why It's So Easy to Overdose

Exactly what caused Prince's sudden death last week is still unknown, but there have been reports that prescription painkillers were found with the singer-songwriter when he died. Experts say there are a number of ways in which prescription opioids can be lethal, particularly if they are taken in combination with other drugs, or if someone starts using the drugs again after a period of sobriety. What's more, people are often not aware of just how easy it can be to overdose on these drugs, said Dr. Scott Krakower, assistant chief of psychiatry at Zucker Hillside Hospital in New Hyde Park, New York.

Teens Who Do Jell-O Shots More Likely to Binge Drink

About 20 percent of underage drinkers in the United States consume alcoholic Jell-O shots, and these youth are also more likely to engage in binge drinking and other risky behaviors, a new study finds. On average, Jell-O shot users consumed 31 alcoholic drinks per month, compared with 19 alcoholic drinks among nonusers. About 73 percent of Jell-O shot users were binge drinkers, meaning they consumed five or more alcoholic drinks in a row, compared with 48 percent of nonusers.

Having More Friends May Mean Feeling Less Pain

People in the study who had larger social networks appeared to have a higher tolerance for pain, according to the findings, which were published today (April 28) in the journal Scientific Reports. In the study, the researchers wanted to see if people with larger social networks had higher levels of chemicals in the brain called endorphins. Endorphins are linked to feelings of pleasure, as well as reduced feelings of pain.

Spanking Makes Kids More Defiant, Studies Suggest

In fact, kids who were spanked were more likely to defy their parents, have mental health problems and be anti-social, the research finds. "Our analysis focuses on what most Americans would recognize as spanking and not on potentially abusive behaviors," Elizabeth Gershoff, an associate professor of human development and family sciences at the University of Texas at Austin, said in a statement. A 2014 UNICEF study found that about 80 percent of parents spank their children worldwide.

Power Up with Pee: New Fuel Cell Could Generate Cheap Electricity

Researchers have developed a way to create affordable and renewable electricity with a fuel cell that runs on urine. The new device relies on natural biological processes of so-called electric bacteria, essentially living cells that eat and breathe electricity. "These electric bacteria are a fascinating type of bacteria that are capable of transferring electrons generated by the breaking down of organic compounds extra-cellularly," said study co-author Mirella Di Lorenzo, a professor in the Department of Chemical Engineering at the University of Bath, in the United Kingdom.
