Three Things You Need to Know Today

Weird New Ways to Make VR Feel Real
VR wants to fool all of your senses. Our own Rachel Metz has tried a new waterproof VR headset, designed to take advantage of the floating sensation of being in water to provide a more immersive experience. Her verdict: it made it “easy to forget about the outside world and just enjoy the weird virtual one.” Elsewhere, researchers have recently developed other systems to trick your body—from weather add-ons to make you feel wind and haptic feedback to help you touch what’s not there, to scent systems that stimulate your nose.

Super-Fast 3-D Printing, Powered by Holograms
A startup called Daqri has developed a device that can create solid objects far faster than regular 3-D printers. Using a new silicon chip that can control the magnitude and time-delay of reflected light to create holograms, the team can cure a light-activated monomer into solid objects in one go—unlike other approaches, which must scan a laser back and forth to achieve the same result. The approach can already create small items, such as a paperclip, in five seconds, which would usually take regular printers minutes.

Uber’s Expanding Prejudice Problem
Ride-hailing firm Uber has discrimination issues inside its HQ as well as out. In a blog post published yesterday, ex-Uber engineer Susan Fowler described a "very, very strange" year working at the company, filled with sexual discrimination and harassment. The company's CEO, Travis Kalanick, insists that there will be an “urgent investigation” into the allegations. The news will be chalked up alongside recent reports of discrimination by Uber drivers, as research shows that travelers with African-American-sounding names suffer longer waits and more cancellations than their white-sounding counterparts.
