You can thank brainy billionaire Elon Musk's Hyperloop proposal for bringing electro-magnetic-powered transportation and the linear induction motor back into the public consciousness.
The Hyperloop is a system for really-really rapid transit. If built, Musk claims it can carry people about 800 miles per hour, which could get you from Los Angeles to San Francisco in about 30 minutes.

"You'll want your camera out for this," Dierig said as he lifted up the lid to a cryogenic freezer capsule. In the cryo chamber, the collection expands to include not just seeds, but animal embryos, semen and microbes.
When unapproved genetically modified wheat was found growing in Oregon earlier this year, it didn't take long for accusations to start flying. A flurry of initial finger-pointing cast potential blame on a federal seed vault in Fort Collins, Colo., which housed the same strain of wheat, developed by Monsanto Corp., for about seven years up until late 2011.
"It's a very curious time in high-energy physics," says Michael Peskin, a researcher at SLAC National Accelerator Laboratory in California. On the one hand, researchers have just made the most significant discovery in decades: In July of last year, they announced they had found the Higgs particle at a collider in Switzerland. The Higgs is part of the mechanism that gives mass to everything. It is so fundamental that without it, we wouldn't exist.

It's bad enough to have to be tested for dementia. It's even worse if the test isn't fair. Researchers in Chicago found they needed to update the screening test for a type of early onset dementia so that the measure would more accurately pick up symptoms among a new wave of patients — baby boomers and Gen Xers.

The conclusion of Beyonce's high-wattage Super Bowl spectacular — and the subsequent blackout in the New Orleans Superdome — are the first and second most tweeted-about moments in Twitter history, according to the social media giant.
A burst of brain activity just after the heart stops may be the cause of so-called near-death experiences, scientists say.
The insight comes from research involving nine lab rats whose brains were analyzed as they were being euthanized. Researchers discovered what appears to be a momentary increase in electrical activity in the brain associated with consciousness.
Although the experiment relied on animals, the results could apply to humans, too, the researchers say.

In my previous life as a high school English teacher, I often felt disconnected from everyone making the decisions that affected how I did my job. A new curriculum handed down from the district. Tutorials to learn how to process student data. Elective classes swapped out for study halls. I just learned to roll with the punches.
But crowdsourcing tools are slowly working their way into the education policy world, designed to give teachers and district employees more say on big decisions that affect their school environment.
