The annual Perseid meteor shower, produced by remnants of the Swift-Tuttle comet, is back. Dean Regas, outreach astronomer at the Cincinnati Observatory, says the best time to see streaks will be in the early morning hours of August 12.
Some psychologists say teaching emotional literacy in school is key to better behavior — and better grades. Marc Brackett and Maurice Elias, two experts in social emotional learning, talk about how emotional literacy is woven into a standard curriculum, and how it can tackle problems like bullying and absenteeism.
Reporting in Science, researchers write of an intravenous vaccine that offered complete protection against malaria in a small clinical trial — but only after five doses. Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases, discusses steps needed to turn this early success into a practical vaccine.

A hacker is somebody who doesn't ask how something works — they just see what works. — Jay Silver
Science and technology now allow us to "hack" solutions to the biggest challenges of our time. But how far is too far? And what are the consequences of these hacks? In this hour, we hear stories from TED speakers who dare to hack the brain, the climate, and even the animal kingdom in hopes of creating a better world.
Mankind has driven species after species extinct. Now Stewart Brand says, we have the technology to bring back the species that we wiped out. So should we? Which ones? He asks a big question whose answer is closer than you may think.
Neurosurgeon Andres Lozano talks about dramatic findings in deep brain stimulation including a woman with Parkinson's who instantly stops shaking, and brain areas eroded by Alzheimer's that are brought back to life.
In the early to mid-1900s, the islands of Hawaii were a far-away, exotic destination. People who managed to get there often kept mementos of that journey including kitschy menus from Hawaiian fine dining restaurants and hotels like like Trader Vic's and Prince Kuhio's.
Now these old menus are serving a purpose beyond colorful relics from the past. Kyle Van Houtan, an ecologist with the National Oceanic and Atmospheric Administration, says he's found a scientific purpose for the menus.
Plant life on our planet soaks up a fair amount of the carbon dioxide that pours out of our tailpipes and smokestacks. Plants take it up during the summer and return some of it to the air in the winter. And a new study shows that those "breaths" have gotten deeper over the past 50 years.
This isn't just a curiosity. Plant life is helping to reduce the speed at which carbon dioxide is building up in our atmosphere. That's slowing the global warming, at least marginally, so scientists are eager to understand how this process works. The new study provides some clues.

A U.S. radar system that tracks thousands of objects orbiting Earth — from satellites to harmful debris — has been slated for shutdown, according to the Space News site. The ground-based network known as the "Space Fence" may cease to operate in October.

Our nearest star is about to pull a once-in-11-years move by swapping its north and south magnetic poles.
The sun's polarity switch is a natural part of "solar max" — the period of peak activity during what averages out to be roughly an 11-year cycle. According to NASA, this year will mark the fourth time since 1976 that scientists have observed the 180-degree pole flip.
