Scientists develop 3D, continuously multidirectional cloaking device

The multidirectional “perfect paraxial” cloak bends light around the hand to show the grid on the wall.

Two University of Rochester scientists have taken invisibility cloaking back to basics. Their novel arrangement of four standard, off-the-shelf lenses keeps an object hidden (and the background undisturbed) as the viewer moves up to several degrees away from the optimal viewing angle.

NightWave: Sleep Assistant

NightWave:  Sleep Assistant 

If you’re having trouble sleeping at night, there’s a good chance it’s because you’re stressed about something, and are unable to get into a relaxed state. But there are many solutions on the market designed to help you calmly drift off when you climb into bed, and the NightWave is one of them. Instead of sounds, medication or a novelty sized club to the head, the NightWave uses a soft blue light that’s just barely visible in a darkened bedroom. The luminance of the light rises and falls, and the idea is that you’re supposed to lay in bed with your eyes open and synchronize your breathing with the light. Over time the rising and falling will become slower and slower, which is supposed to relax your body to the point where you’ll drift off to sleep.

Scientists Directly Observe Three Distant Planets

Scientists Directly Observe Three Distant Planets 

 The Hubble Space Telescope captured a fuzzy image of the planet, known as Fomalhaut b, which is no more than a white speck in the dust ring that surrounds the star.

A little more of the universe has been pried out of the shadows. Two groups of astronomers have taken the first pictures of what they say – and other astronomers agree – are most likely planets going around other stars.
