X-ray astronomers have reported a bizarre X-ray emitter in the direction of our galactic centre. C Kouveliotou and colleagues have seen this object in the intensity records of the large area
A team led by B Phillips and Paul Lett at the National Institute of Standards and Technology, Maryland, US, have observed the retardation effect, that is, the small but finite delay between the
If caught, it could spell trouble for the Standard Model of particle physics; although success has eluded most scientists, a group of relentless researchers refuse to give up the search for a free quark
X ray holography, a neoteric way of studing atomic configurations, promises to give a three dimensional picture of the arrangement of atoms in a crystal
Far away from the sun but exceptionally bright, the comet Hale Bopp has baffled a lot of scientists who are struggling to explain its strange behaviour
Designers from the Research Centre of Building Power Tools, Russia have designed tools that, they claim, disobey the sacrosanct third law of motion laid down by Newton. The tools are specially
Manufacturers today are looking for ways to pack in more data in laser discs. But the most commonly used lasers emit red light which has a longer wavelength compared to blue light. Attempts to
The origin of magnetic fields associated with galaxies is still a matter of debate. One theory attributes it to a dynamo-like mechanism in rhe galaxies, while the other contends that the dynamo
The present generation of supercomputers has been using custombuilt processors which are very difficult to maintain. Now, if the Accelerated Strate~c Computing lnitiative, a US department
