London, April 17 : Researchers studying ultra-cold atoms have made a clock that takes 300 million years to lose just one second.
The atomic clock, which is twice as accurate as any similar device made previously, may believably turn out to be useful for measuring distances to far away galaxies, or for tracking tiny movements in the Earth''s crust that may give a warning of earthquakes.
Its makers have revealed that the clock consists of gas atoms trapped in a magnetic field and cooled almost to absolute zero, or minus 273 Celsius, the coldest temperature permitted by the laws of physics.
With the consistent, almost two months-long efforts of the scientists at the Institute of Genomics and Integrative Biology (IGIB), New Delhi, a striped 'Zebra fish,' picked up from a rivulet in Assam, has become the first vertebrate in India to have its whole genome sequenced.
Washington, April 16 : A team of biologists is studying a tiny and diverse group of marine organisms to find how plant cells, that live in the oceans and serve as the basic food supply for many of the world's sea creatures, react to climate change.
The team, from the University of Iowa (UI), includes Debashish Bhattacharya, professor of biological sciences in the UI College of Liberal Arts and Sciences.
They are studying a tiny (about one micrometer in diameter) and diverse group of organisms called picoeukaryotes.
Washington, April 16 : Scientists at Rice University, US, have uncovered a room-temperature chemical process that splits carbon nanotubes to make flat nanoribbons, which can be used to create basic elements for aircraft, flat-screen TVs, electronics and other conductive products.
The technique makes it possible to produce the ultrathin ribbons in bulk quantities.
These ribbons are straight-edged sheets of graphene, the single-layer form of common graphite found in pencils.
One would have to place thousands of them side by side to equal the width of a human hair, but tests show graphene is 200 times stronger than steel.
Washington, April 16 : In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique.
For controlling the spin of electrons, the team bounced electrons through a microscopic channel of precisely constructed, two-dimensional layer of semiconductor.
It's the first time the intrinsic properties of a semiconductor, not external electric or magnetic fields, have been used to achieve the effect.
Washington, April 17 : NASA's Kepler mission has taken its first images of the star-rich sky where it will soon begin hunting for planets like Earth.
