The original application was registered suo-motu based on the news item titled "Nayar …
LINKING together individual molecules to make complicated structures, much in the same way as children playing with Lego, chemists are now trying to construct materials whose properties they can fix beforehand. At least half a dozen groups in USA, Canada, Europe and Australia are assembling large arrays of molecules to …
WHILE CHOOSING a fabric, fingers may be the best judge of a cloth's quality, but they are not reliable in predicting the cloth's behaviour after it is tailored. Now, a mathematical technique called fuzzy-set theory, may enable textiles to be designed according to predetermined attributes related to comfort and performance …
THIS IS the centenary year of Physical Review, one of the leading journals on physics. The journal has grown from its humble beginnings in New York in 1893, to become an institution in its own right. And though in the first few decades of its existence it was primarily a …
AMERICAN physicists are taking increasingly to a computer-based electronic bulletin board developed by physicist Paul Ginsparg that enables them to exchange research information. Physicists can use the system to submit unpublished papers or scan papers submitted by other scientists and they can access the system from anywhere (Science, Vol 259, …
CAN WE unravel the composition of all objects -- both living and non-living -- as just an interplay of a handful of particles? Since time immemorial, humans have tried to make sense of their complex world by assuming a fundamental, underlying simplicity of structure. Until around 1950, scientists believed atoms …
HEAT ALWAYS flows from a hotter body to a cooler one, according to the second law of thermodynamics. But then why is the Sun's atmosphere hotter, by several million degrees, than its surface where all the energy is generated? Astrophysicist Jack Scudder has furnished an ingenious mechanism to explain how …
ONE OF the most remarkable and exciting developments in physics has been the interaction between particle physics and cosmology. Remarkable, because it combines the study of the very small, namely, particle physics, with the study of the very large, namely, cosmology. Exciting, because each is contributing immensely towards answering fundamental …
PARTICLE physicists scanning the cosmos for the slippery neutrino, claim once again to have established that it has a mass. Anthony Turkevich of the University of Chicago and his collaborators have published a study claiming to have uncovered "another independent line of evidence pointing towards neutrinos having mass." Predictably, this …
BIOLOGY Yellow pigment clue to evolution Bilirubin, responsible for the yellowish tinge in the skin, eyes and nails of jaundice patients, has for the first time been identified in plants. The pigment was discovered in Strelitzia reginae Aiton, commonly know as the Bird of Paradise plant. It is indigenous to …
