Hypnotizing Lights Look Friendly Until They Trap You
Isotopes v.2 looks alluring. All those pretty, pulsating lines of light draw people in. Relaxing. But once they get in there, things start to change. The lights become more constant and intense. Basically they put people in a somewhat oppressive light prison. Soooo, probably not relaxing.
Watch A Face Morph Eerily With Nothing But Lighting Shifts
One element has enormous power to alter the look of a person on film or video — lighting. Cinematographers and photographers are intimately familiar with this fact, but this video really brings the point to life.
Philips’ Prototype LED Could Save Billions Annually
Office parks and convenience stores rely on fluorescent lights. These flickering gas-filled tubes suck down far less energy than the incandescent bulbs they replaced, but they still consume some 200 terawatts of electricity every year. This new super-efficient LED prototype from Philips, however, puts florescents to shame.
Hollow Fibre Optic Tunnels Can Blast Data At Practically The Speed Of Light
We all want faster downloads, and developments like graphene antennas promise a speedy future. There is an upper limit — the speed of light — but that should be fast enough, right? Well, a new kind of hollow fibre optic cable promises to get us 99.7 per cent of the way there.
What Is Light, Anyway?

NASA’s Latest Engineering Challenge: How To Change A Light Bulb
NASA is changing all of the light bulbs on board the International Space Station to help famously insomniac astronauts sleep better. Astronaut insomnia is somewhat legendary at NASA, with astronauts popping sleep pills with regularity and averaging only six hours of sleep a night, far less than the eight and a half hours they’re technically allotted.
How Can We See Light?
Light is tricky. You probably know that we experience “light” by seeing it bounce off something before being absorbed into our eyes. But what about light itself? That’s much tougher, since in order to see the light, it has to be absorbed. Solving for this little Catch 22 won Serge Haroche the 2012 Nobel Prize in physics.
