How scientists made fast quantum communication possible

How scientists made fast quantum communication possibleWashington, April 30 : Researchers from Toshiba and Cambridge University's Cavendish Laboratory have developed high speed detectors that are capable of receiving information with much higher key rates, thereby able to receive more information faster, in a technique known as quantum cryptography.

Native Americans descended from a single ancestral group

 Native Americans descended from a single ancestral groupWashington, April 30 : In a new research, an international team of scientists has determined that the Native Americans, who came to the New World, descended from a single ancestral group.

"Our work provides strong evidence that, in general, Native Americans are more closely related to each other than to any other existing Asian populations, except those that live at the very edge of the Bering Strait," said Kari Britt Schroeder, a lecturer at the University of California, Davis, and the first author on the paper describing the study.

‘Chevrons’ are not evidence of megatsunamis, say scientists

 ‘Chevrons’ are not evidence of megatsunamis, say scientistsWashington, April 30 : A new research has refuted the hypothesis that `chevrons', large U- or V-shaped formations found in some of the world's coastal areas, are evidence of megatsunamis caused by asteroids or comets slamming into the ocean.

The research was done by University of Washington (UW) geologist and tsunami expert Jody Bourgeois.

Anxiety drug can treat restless legs syndrome, improve sleep

Anxiety drug can treat restless legs syndrome, improve sleepWashington, Apr 30 : A drug, called pregabalin-commonly used to treat seizures and anxiety-has now been implicated as an effective treatment for restless legs syndrome (RLS), according to a study.

The 12-week study involved 58 people with RLS, out of which, 30 received the drug pregabalin and the rest received placebo.

The researchers performed sleep studies at the beginning and end of the research.

Almost two-thirds of the people who took pregabalin were found to have no RLS symptoms while taking the drug.

She said that their long-distance love leaves them both wanting more.

Brighter, full-colour electronic readers coming your way

London, Apr 30 : Buying an e-reader but not sure if you''d like reading the dim screen? Well, then get ready for e-book reading experience that will be as close to printed media as possible.

Scientists have announced, what is known as Electrofluidic Display Technology (EFD)- the first technology to electrically switch the appearance of pigments in a manner that provides visual brilliance equal to conventional printed media.

The work by an international collaboration of the University of Cincinnati, Sun Chemical, Polymer Vision and Gamma Dynamics, could offer better than 85 percent "white-state reflectance."
