What can't 3D printers do? We've all heard news stories about 3D-printed food and medical prostheses—even cars and entire houses. But how does additive manufacturing, as it's also known, really work? And how can an at-home hobbyist get started? Ira teams up with Makerbot's Bre Pettis to present the ultimate beginner's guide to 3D printing.

Lightning -- one of the great unsolved mysteries.
A new study in Science investigates the wisdom of crowds... well, schools. Andrew Berdahl, graduate student at Princeton University, explains that Golden shiner minnows prefer shady habitat. And he and his co-authors found that large groups of fish are better at tracking shady habitats than smaller groups or individuals--a demonstration of collective sensing.How do fish pool their senses? The researchers filmed fish and digitized their movement to try to answer the question.
In 2011, comet Lovejoy traveled through the sun's corona and lived to tell the tale. But its tail was the most telling. Reporting in the journal Science, Cooper Downs, an astrophysicist at Predictive Science Inc. in San Diego, Calif., says that the wiggly path of the comet's tail helps explain the sun's magnetic field.
The Rockaways, a Queens, N.Y. neighborhood, is still recovering from Sandy. Debris from fires lingers on the streets, and buildings torn apart by the storm are crumbling on the beach. But at least for those with restored heat and power (7,000 customers in the area are still without power), there is yet another worry: mold. Peter Corless, a community organizer in the Rockaways, gives us a tour of the neighborhood, while Joan Bennett, a mycologist whose house molded after Katrina flooding, describes the species of fungi she found in her own home after that hurricane and in New Jersey homes post-Sandy.
Ask a child with an imaginary companion if their pretend friend is real, and often they'll tell you, "I just made them up!" Of course, moments later they'll regale you with stories of the latest adventures with their companion with the utmost conviction. In the second episode of The Real Guide to Imaginary Companions, a trip into the lab of developmental psychologist Jaqueline Woolley reveals how children can become so enamored of their pretend friends that they blur the lines between reality and fantasy. Woolley also investigates whether a child's orientation toward fantasy play has ties to real-world creativity.

Up and down the West coast of the U.S., bees are leaving their hives, flying around at night and then suddenly dropping dead. Learn all about this parasitic horror that quietly zombifies these insects and how you can become a real-life zombee hunter.
Ice can be hard to get a handle on, literally and figuratively. It can be cloudy or clear, as hard as concrete or as soft as a snowflake. Ice experts Erland Schulson, head of the Ice Research Lab at Dartmouth College, and Shintaro Okamoto, founder of Okamoto Studio in Queens, New York, have staked their livelihoods on the slippery material. We asked them what fascinates them about frozen water. (Originally published Jan 27, 2012)
Science Friday salutes a great science teacher. "Office hours are some of my favorite hours of the week," says professor Tom Carlson, a medical doctor, ethnobotanist and instructor of 1700 students annually at the University of California, Berkeley. One of Carlson's former students, SciFri associate senior producer Christopher Intagliata, told us that Carlson's class was the reason he got into science. Listen here: http://www.sciencefriday.com/s....egment/05/31/2013/te
For honey bees, making is a new queens is a simple as adding royal jelly, a unique protein rich secretion, to the cell of a growing larvae. This fairly well studied addition causes a cascade of physiological changes in the growing larvae and voila! A queen is born. However, what causes a baby bumblebee (the fuzzier and more weather-hardy cousins to honey bees) to become royalty remains a mystery. They don’t produce royal jelly but they produce a unique barf for their young. Enter entomologist Hollis Woodard and her students at UC Riverside who hope that by understanding how queens are created, they can mitigate on-going extinction crises in bumblebees species. Woodard and company begin by heading up to San Bernardino mountains outside Los Angeles. Here, the researchers collect emerging queens as they buzz around the blooming Manzanita shrubs. These queens are brought back to the lab, where the establish their own (see through) honeypots. Lavished with food by the lab members, the queens lay dozens of larvae which become daughter drones. These drones are then “milked” for their barf which is analyzed for its chemical properties. Future larvae are hand fed the analyzed barf in various quantities and intervals to determine what factors lead to the generation of queen bees.
