Researchers at the University of Cambridge have discovered a way to use lasers to remove toner ink from paper so that it can be reused instead of being recycled or, worse, tossed in the garbage. In the future, those old TPS reports taking up space on your desk could quickly be turned into clean sheets of paper by sending them through an "un-printer."

The researchers studied 10 different laser setups ranging in strength and pulse d... (View original article)

The team, led by Professor Charles H. Sykes, plans to submit the breathtaking achievement to Guinness World Records. The new class of device could be used in applications ranging from medicine to engineering.

The single molecule electric motor measures one nanometer across, which is one billionth of a meter. This means,... (View original article)

Researchers at Cornell University have made an astounding leap forward in cloaking technology. While other teams have been working on what have been traditionally seen as “invisibility cloaks” – using

meta-materials

to hide an object from visible light — this team has been working on something a bit more

ambitious: hiding an actual event in time.

Current work in developing invisibility cloaks tri... (View original article)

Since the early days in the 1940s, computers have routinely been described as “brains” — giant brains or mathematical brains or electronic brains. Scientists and engineers often cringed at the distorting simplification, but the popular label stuck.

Wait long enough, it seems, and science catches up with the metaphor. The field of “cognitive computing” is making enough progress that the brain analogy is becoming more apt. I.B.M. researchers are announcing... (View original article)

People see winter as a cold and gloomy time in nature. The days are short. Snow blankets the ground. Lakes and ponds freeze, and animals scurry to burrows to wait for spring. The rainbow of red, yellow and orange
autumn leaves has been blown away by the wind turning trees into black skeletons that stretch bony fingers of branches into the sky. It s... (View original article)

Computers synthesize sounds -- from fire to frictional contact -- to go with graphics
Provided/Doug JamesRapid movement of heated gases generates high-frequency sounds that are an important part of the sound of fire, but computer-generated images don't simulate those details.

A new hypothesis claims the Earth may once have had two moons, which eventually crashed together forming our current celestial partner.

This new idea, reported in the journal Nature, could explain a long standing puzzle about the differences between the near and far sides of the lunar surface.

The near side is relatively low and flat with many large dark basalt mare, while the far side is high and mountainous, with thicker crust.

The work, based on computer simulati... (View original article)
