"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.
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.
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?
Religious beliefs are often (though not always) comforting. The idea of an afterlife can be attractive. Ideas like fate and destiny — or simply things happen for a reason — can make it easier to cope with difficult situations. It's nice to think that humans have a purpose, that we were put here for some reason, that the natural world is meaningful.
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But before he began his life of crime, Walter White was a chemistry teacher, and chemistry is what originally made him such a great meth cook.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.
Algae blooms are green or red or brown, slimy, smelly and you don't want it coming soon to a waterfront near you.
Most of us don't give a lot of thought to algae until the furry-like monstrosity is spreading over beaches, rivers, lakes and bays, but gigantic algae blooms have become an increasing problem around the world.
The danger algae blooms pose is that they sap the body of water where they are growing of nutrients and oxygen; they then die, decompose and rot.
Now, to a story I'll do entirely in haiku, so bear with me. And just in case you need a primmer: just three lines of verse. Syllables are what counts here - five, seven, then five. For the last few months, scientists have collected haikus meant for Mars. Thousands of poets, pros and amateurs alike, submitted their work. The public then picked their favorite Mars haikus. We are fans of these, by Anonymous.
UNIDENTIFIED MAN #1: (Reading) Mars, oh. Do forgive. We never meant to obstruct Your view of Venus.
This is WEEKEND EDITION from NPR News. I'm Rachel Martin. It is August. Chances are where you are it's hot. So, maybe you want a drink to cool off. Will it be fruity or fizzy, maybe boozy? Whatever it is, Dan Pashman, host of the Sporkful podcast, thinks you may be overlooking one key ingredient: the ice. He joins us now from our New York studios. Hey Dan.
DAN PASHMAN, BYLINE: Hi, Rachel.
MARTIN: So, ice. This seems like a fairly forgettable part of a beverage experience. You say, no. Why?
Ah, the road trip - one of the great American summer rituals. But sharing this great tradition with other road trippers can also be intensely frustrating. Perhaps you've found yourself wondering why traffic jams take so long to clear up or why they seem to last so much longer than a crash. Well, Bill Beaty is a research engineer at the University of Washington. He has a little advice about that.
