"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.

The city of London has ordered a company to cease tracking the cellphones of pedestrians who pass its recycling bins, which also double as kiosks showing video advertisements. The bins logged data about any Wi-Fi-enabled device that passed within range.
The company, called Renew, recently added the tracking technology to about a dozen of the 100 bins it had installed before London hosted the 2012 Summer Olympics.
It's breathing, he thought. "All of a sudden I see a thing with a heartbeat."
John Nelson is a designer, well known for tracing complex weather patterns or cultural information on maps, so considering what he usually does, this was easy. NASA's Visible Earthteam publishes pictures of our planet every month of the year, so John thought, why not stitch them together, and see what the seasons look like from outer space?
Bloomberg scored the big scoop and got Elon Musk — the founder of Tesla, SpaceX and Paypal — to explain his vision for a high-speed mass transit vehicle that could deliver you from Los Angeles to San Francisco in an astonishing 30 minutes. Musk explained that the Hyperloop pods would leave every 30 seconds and would run inside "low pressure" tubes. Bloomberg continues:
Perhaps you heard that last night, a plucky little drug dealer named Walter White returned to television for his last eight episodes of the award-hoarding Breaking Bad.
But before he began his life of crime, Walter White was a chemistry teacher, and chemistry is what originally made him such a great meth cook. Breaking Bad has always included a lot of science talk, especially in the early days, and the time has come for someone to see whether it holds up.
