Everyone wants to be free; or at least have some choice in life. We all have our professional, family and social commitments. On the other hand, most people believe that they are free to choose what to do, from the simplest to the more complex: should I drink coffee with sugar or sweetener? Do I put some money in the savings or do I spend it all? Who should I vote for in the next elections? Should I marry Carmen or not?

The question of free will is essentially a question of agency, of who is in charge as we go through our lives making all sorts of choices.

A creature that lived 375 million years ago and is thought to have been the first fish to have made the transition to land sported large pelvic bones in addition to its leg-like front fins, new research shows, suggesting that it was a more efficient walker than previously thought.

Tiktaalik roseae, discovered in 2004 on Ellesmere Island in Nunavit, Canada, is a key transitional fossil that links lobe-finned fishes and tetrapods, the first four-limbed vertebrates at the end of the Devonian period.

Spinach Dinosaurs To Sugar Diamonds: 3-D Printers Hit The Kitchen

Originally published on Thu January 16, 2014 3:52 pm

A mathematician's sweet dream: For about $10,000, you can print out rainbow sugar dodecahedrons and interlocking cubes.
3D Systems

From cool casts for a broken arm to impressive replicas of Michelangelo's David, 3-D printing has come a long way in the past few years.

In fact, the technology is moving so fast that 3-D printers might be coming to your kitchen this year — or at least, to a bakery or bistro down the street.

Right now, as you are reading these very words, trillions of particles called neutrinos are streaming through your body. Hardly a single atom in your body feels their passage. Hardly one of the trillion neutrinos feels your presence. They are ghosts to you as you are to them. But that doesn't mean these tiny flecks of matter don't matter.

Neutrinos, it turns out, have shaped the universe and their remarkable story has now been expertly told in a new book by astrophysicist Ray Jayawardhana. It's called Neutrino Hunters.

Robert Krulwich NPR

Imagine a couple of million years ago, a curious young alien from the planet Zantar — let's call him a grad student — lands on Earth, looks around and asks, "Who's the brainiest critter on this planet? Relative to body size, who's got the biggest brain?"
