The Most Amazing Science and Tech Pictures of the Week, Sept. 26-30

After realizing that the PopSci editors' chat room is awash in amazing pictures that don't necessarily see the light of day on our site (due to oldness, redundancy, or a host of other dealbreakers) we thought: why are we keeping these to ourselves? Here are the pictures this week that made us gawk, laugh, and email the .jpg links to our friends, from a perfectly geometrical haircut to a dude gliding through a giant Chinese cave in a wingsuit.

Wingsuit Flyer

American Jeb Corliss, wearing a wingsuit, jumped out of a helicopter at 6,000 feet and glided through the massive Tianmen Cave in Hunan Province, China. He landed safely, thanks to a parachute.Getty Images

Geometric Haircut

There's more to Nick Sayers' rhombus-based haircut than meets the eye. To quote MAKE: The obtuse angles of each rhombus meet in groups of three, but the acute angles meet in groups of five, six, or seven, depending on the curvature. In the flatter areas, they meet in groups of six, like equilateral triangles, and in the areas of strong positive curvature they meet in groups of five, but in the negatively curved saddle at the back of the neck, there is a group of seven.Nick Sayers

QuailBot

Quail chicks were exposed to warming robotic hens, one stationary and one mobile, 36 hours after birth. The chicks that were paired with the mobile robot developed better spatial abilities than the the chicks with the stationary robot.E. de Margerie, et al. ©2011 IOP Publishing Ltd

Mathematical Pasta

Architect George L. Legendre's new book, Pasta By Design, catalogues the precise mathematical layout of different kinds of Italian pasta. Pictured here: the noble cavatelli. Read more at the New York Times Magazine.George L. Legendre

Saturn's Moons

Mind-Reading Ultrasound

New research from the University of Toronto suggests that "ultrasound-based devices could lead to a new kind of brain-computer interface." This headgear could tell with pretty impressive accuracy whether wearers were performing a word game or an object-rotation game in their heads. Read more at IEEE Spectrum.Pierre Duez

Solar Sail

This proposed solar sail is the largest ever proposed--four times larger than any sail on Earth, and seven times larger than any in space. It could be used to more accurately show weather warnings and analyze solar flares. Read more at NASA.NASA

Gaaaah!

An example of the Creepiest Software Ever, which overlays other people's faces on top of your face. Here: Michael Jackson (RIP, you weird-faced genius) on top of creator Kyle MacDonald's face.Kyle MacDonald

Laser Pointer Bomb Detection

Researchers have developed a tool to detect roadside bombs that uses the same power output as a laser pointer. The low intensity laser can detect just a fraction of a billionth of a gram of explosive material.Michigan State University

Dog Beach

Boston Dynamics' Big Dog has turned five, and its proud roboticist creators have compiled a video of highlights from its life, full of half playful, half terrifying robotic movement.via Youtube

Mind Reading Video Reconstruction

Jack Gallant, a neuroscientist at U.C. Berkeley has reconstructed clips from brain images scanned from subjects watching movies. It has yet to effectively recognize mustaches.Jack Gallant
