Few revolutions can be said to have lasted for half a century, or to have wrought disruptive change at a predictable pace.
But that's exactly the case with the digital revolution, which has seen computing get dramatically faster, cheaper and smaller every few years since the 1950's.
Psychology Professors Henry Roediger and Mark McDaniel are experts on human learning and memory. "People underestimate how many times they need to practice something before they really know it." Think you'll be fine running through information once or twice? Wrong. Experts say you need to review five to seven times. That's why it's best to break up study and do a little bit every day.
Professor Roediger says there's a temptation to re-read the textbook before a test. Not a good idea. That just gives the brain a false sense of how much the student really knows.
Stroke survivors may soon be able to improve their rehabilitative success at home by using a robotic glove fitted with sensors, developed by European scientists. The glove helps overcome the hand and wrist damage typically associated with strokes.
The glove has sensors that allow therapists to monitor patients' progress remotely. Captured data helps patients tailor their therapy, using specialized video games.
Not only does NASA's chief scientist believe alien life forms likely exist, but she said the space agency knows where to look and could discover signs of extraterrestrial life within the next decade. Speaking on a panel discussion recently about water in the universe, NASA's chief scientist Ellen Stofan said she believes the first indications of alien life could come by 2025 -- with more concrete evidence of extraterrestrial life coming in 20 to 30 years. "We know where to look. We know how to look," she said. "In most cases we have the technology, and we're on a path to implementing it, so I think we're definitely on the road." While Stofan predicts mankind is likely not alone in the universe, she said she expects alien life won't be "little green men." "We are talking about little microbes," she said. Water is one of the necessary elements in NASA's quest to find habitable planets and life forms beyond Earth. It's been found in surprising places, including the icy moons of Jupiter and Saturn. By exploring these other worlds, it's only a matter of time before NASA could strike on evidence proving the existence of alien life.

Sure, Tylenol can ease your pain, but it also reduces your pleasure.
Four years ago at age 35 Nick Zesso was diagnosed with the deadliest form of brain cancer, glioblastoma. He had surgery and radiation, but when the tumor returned three years later, more surgery and chemotherapy couldn't stop it. His mother thought he was going to die, but that all changed when Dr. Ashley Sumrall mentioned a new device that attaches magnets to the scalp.The Optune uses alternating electric fields to stop cancer cells from dividing, which ultimately kills them. The Optune is expensive. It costs about $20,000 a month. So far it is only approved for patients whose brain cancer has returned.
Destructive hacking attempts targeting critical infrastructure in the Americas are more widespread than commonly believed. A survey by the Organization of American States or OAS of more than 570 critical infrastructure organizations in North and South America found surprisingly high numbers are targets of destructive attacks. Forty percent of respondents say hackers attempted to shut down their computer networks. Forty-four percent said they faced attempts to delete files. And fifty-four percent said hackers tried to control equipment. Reuters reporter Joseph Menn calls the figures mind-blowing.
A new study links taking muscle-building supplements, such as pills and powders with creatine or androstenedione, with an increased risk of testicular cancer.
Moreover, says study senior author Tongzhang Zheng, the associated testicular germ cell cancer risk was especially high among men who started using supplements before age 25, those who used multiple supplements, and those who used them for years.
If you could find out your baby's future health problems right after he or she was born, would you want to know? Some new parents will get to make that decision soon. This month, doctors in Boston will begin the BabySeq project, in which they will sequence the genomes of newborns to look for signs of diseases that begin in childhood.
We love making predictions at FiveThirtyEight, but we know that they'd be meaningless if we didn't check to see how accurate they turned out to be. Over the past month, we forecast every NCAA college basketball game for the women's and men's tournaments, updating our numbers almost a hundred times as 132 teams were pared down to two champions.
