The simple tricks to fool Earth-evolved humans into living on Mars time. One Hour Short of Mars Time A new study says exposure to blue light at the right times, along with smarter caffeine use, can help humans adjust our biological clocks to the 24.6 hour Mars day rather than Earth's day.

Now two physicists – James Hill and Barry Cox from the University of Adelaide in Australia – have shown that Einstein's theory of special relativity can be logically extended to allow for faster-than-light motion. They're quick to point out that their finding in no way contradicts the original theory, but simply provides a new aspect of it.

'Tractor beams' of light that pull objects towards them are no longer science fiction. Haifeng Wang at the A*STAR Data Storage Institute and co-workers have now demonstrated how a tractor beam can in fact be realized on a small scale.

When we look up on a dark night, we see a sky filled with stars. The light from a star, like the light from a flashlight or a lightning bug, is one form of electromagnetic radiation. Light is formed of waves, and different colors of light have different wavelengths. Articles about ASTRONOMY: http://www.scoop.it/t/science-news?tag=astronomy

Einstein's classic thought experiment involves sitting on a train travelling at the speed of light. If you hold a mirror in front of your face, will you see your reflection in a mirror? How could light from your face reach the mirror if the mirror is travelling away from you? But it would be a pretty spooky train if you couldn't see your reflection so Einstein felt this solution wasn't realistic. On the other hand if you could see your reflection, it would mean light was travelling at the speed of light inside the train. But that meant the same light observed from outside the train would be going twice the speed of light. This again seems inconsistent. So Einstein resolved that you must see your reflection but that light must travel at the same speed inside and outside the train. The only way this is possible is if space and time are perceived differently by observers inside and outside the train.

Day length helps plants determine when to bloom and is sensed by proteins tuned to blue-light wavelengths in the leaves of Arabidopisis thaliana. These proteins, in turn, help switch on genes that trigger flowering in springtime, a new study reveals. A. thaliana tissues where proteins that measure day length reside are shown stained in blue.

Mild mannered though they seem, plants are extremely competitive, especially when it comes to getting their fair share of sunlight. Whether a forest or a farm, where plants grow a battle wages for the sun's rays.

There's always a lot of fuss about getting other things to go as fast or faster than the speed of light. But what about changing the speed of light? Is there anything useful we could do by slowing light down rather than speeding things up?
