Cool! http://ketr.org/post/transformer-paper-turns-itself-robot-cool Every so often, a scientific paper just begs for a sexy headline.<p>Consider this study in the current issue of <em>Science</em>: "<a href="http://www.sciencemag.org/lookup/doi/10.1126/science.1252610">A Method for Building Self-folding Machines</a>." A bit bland, you'll no doubt agree. <em>A Real-Life, Origami-Inspired Transformer</em> is how the journal's public affairs department referred to it.

Mystery Bursts Baffle Astronomers http://ketr.org/post/close-encounters-radio-kind-mystery-bursts-baffle-astronomers Astronomers have a mystery on their hands. Two large radio telescopes, on opposite sides of the planet, have detected very brief, very powerful bursts of radio waves.<p>Right now, astronomers have no idea what's causing these bursts or where they're coming from. And nothing has been ruled out at the moment — not even the kind of outrageous claims you'd expect to see in tabloid headlines.<p><strong>Australian Recordings Inspire Curiosity And Doubt</strong><p>The first report of these "fast radio bursts" appeared in 2007.

I'M Tess Vigeland. Let us contemplate the American teenage girl, perhaps the very first one. Apparently, there's been some scientific debate about who she is and whether she hails from the same gene sequence as what we think of as the first Americans, American Indians. And when I say gene sequence, we're not talking about Skinnies from Urban Outfitters.

But faith is also impelling Bryan Shaw to create software to detect eye cancer in children as soon after birth as possible.<p>The Shaws are Christians, and their faith is extremely important to them. When they were at their bleakest, "Bryan would pull out the Psalms and say, 'This is how King David suffered in the Psalms, and we're going through this," says Elizabeth.

We've always been told that magnets have two poles, north and south. But theory suggests there should be something called a magnetic monopole, a magnet that has either a north pole or a south pole but not both of them. So far no one has found this elusive magnetic monopole.<p>As part of his project, Joe's Big Idea, NPR's Joe Palca brings us the story of scientists at Amherst College in Massachusetts. They have created a synthetic magnetic monopole. Fri, 31 Jan 2014 10:04:00 +0000 Joe Palca 48837 at http://ketr.org
