When Water Flows Uphill
*** http://www.patreon.com/scifri - Please Help Support Our Video Productions *** In the Leidenfrost Effect, a water droplet will float on a layer of its own vapor if heated to certain temperature. This common cooking phenomenon takes center stage in a series of playful experiments by physicists at the University of Bath, who discovered new and fun means to manipulate the movement of water. Researchers test ridged surfaces in order to control the movements of hot water.

Tiny Living
Chris Tack made seven trips to Goodwill to get rid of his stuff, before moving into the 140-square-foot home he and his wife Malissa Tack designed and built. Constructed on a trailer bed and parked in Snohomish, Washington, the house is more than enough space for them, the couple says. And one advantage of a home on wheels, the 29-year-olds say, is that you can always move.

Shake Your Silk-Maker: The Dance of the Peacock Spider
*** http://www.patreon.com/scifri - Please Help Support Our Video Productions *** With their ornately-colored bodies, rhythmic pulsations, and booty-shaking dance moves, male peacock spiders attract the attention of spectating females as well as researchers. One such animal behavior specialist, Madeline Girard, collected more than 30 different peacock spider species from the wilds of Australia and brought them back to her lab at UC Berkeley. Under controlled conditions, she recorded their unique dances in the hopes of deciphering what these displays actual say to a female spider and how standards differ between species.

Babies on the Brink
Since the 1960s, developmental psychologists point to the "Visual Cliff"—an experiment that plops babies on a fake precipice—as proof that infants learn to fear heights as they learn to crawl.

The room, created by Los Angeles artist Julian Hoeber and on display at the Harris Lieberman Gallery in New York, is modelled on a stock roadside attraction, Hoeber says. It's based on a simple trick: the room is tilted on a compound angle. The result is disorienting and highly popular -- drawing about 20,000 people when it appeared in L.A. Michael Landy, professor of neural science and psychology at New York University, explains how the piece creates a battle between our senses.

He researches whether there are any related animals alive today, or existing fossils that may shed light on how the bone fragment fits into a larger piece, and reconstructs the entire skeletal system. He then sketches in muscle groups, and adds skin and color considering where the animal lived and during what period of time.
