LIFE IMITATES art more than art imitates life, said Oscar Wilde. His statement was borne out recently when US scientists re-enacted in their laboratory the plot of Steven Spielberg's latest film, Jurassic Park, which shows dinosaurs being re-created from their DNA, procured from the blood sucked by mosquitoes and preserved …
IF YOUR heart is in the wrong place, perhaps a gene is responsible for it. Researchers have recently identified a gene that plays a major role in deciding whether the internal organs in mice should be assigned to the right or left of the body and this has initiated the …
FIVE YEARS ago, 52-year-old Don Nelson could barely walk because Parkinson"s disease had reduced him to a cripple. But today, thanks to the foetal-tissue therapy that he underwent in 1988, he is up and about, takes less medication and can once again indulge his passion for wood-carving. The new world …
US SCIENTISTS are making the most elaborate efforts yet to detect gravitational waves, which are the distortions in the fabric of space and time predicted by Albert Einstein's theory of relativity. These waves are produced during violent events in the universe, such as the collision of two neutron stars or …
TWO US oceanographers have used powerful supercomputers to perform the best-ever simulation of the world's ocean movements -- an important step towards forecasting how changes in ocean circulation will affect global climate over the next century. Albert Semtner of the Naval Postgraduate School in Monterey and Robert Chervin of the …
PARASITIC flies that lay eggs in bumble-bees would not be so smug if they knew that the bees have a way of hitting back.

ANTS ARE hindering the return of forests on millions of hectares of abandoned pastures in Brazil by feeding on seeds of trees. According to a team of Brazilian and American researchers, two ant species -- Pheidole puttemansi and Solenopsis aurea found in the grasslands -- are voracious consumers of tree …
Cables as messengers of information between computers are on their way out. A cableless computer network called WaveLAN, in which each computer is provided with an antenna that picks up data in the form of radiowaves, was launched recently in Britain (New Scientist, Vol 138, No 1874). The new technology …
Two British consultants have developed an underwater pump that can irrigate riverside fields without using fuel or causing pollution. The prize-winning turbine is easy to construct and can work continuously (Ceres 141, Vol 26, No 3). Originally designed to harness the energy of the Nile to irrigate the desert areas …

ARTHUR Nonomura, an American scientist-turned-farmer, may usher in another green revolution with his discovery that methanol (or methyl alcohol), traditionally thought to be toxic to plants, can stimulate crop growth in hot and dry regions. "I think it's going to save the world," says Andrew Benson of Scripps Institution of …
EVEN AS Calcutta's transport authorities plan to phase out the tram, it is making a comeback in other parts of the world as technology's solution for a low-cost, non-polluting urban transport system. British firm JPM Parry and Associates has developed a modern tramway system, which does not require overhead wires …
ELECTRICITY may soon be used to clean up chemical-contaminated soils using a new technology, which has been developed by scientists at the Massachusetts Institute of Technology (MIT). The technology, which is expected to be put on trial by the end of next year, will cost about $25 per tonne. Current …
SUFFERING from chronic asthma? Try swallowing a live fish and you may never wheeze again. For more than 150 years now, thousands of people have been gathering once every year in a bylane in the old city of Hyderabad, to avail of a secret herbal medicine that is placed inside …
MILK PRODUCERS in Tamil Nadu's Nilgiri district have designed a portable, insulated biogas plant that produces enough gas for three hours of cooking per day. The one cubic metre capacity prototype, developed by the Nilgiri District Cooperative Milk Producer's Union, is a miniature of the now-famous, floating-dome type of biogas …
NEXT TIME you liberally smear suntan lotion on your body and linger too long in the sun, beware: Sunscreens are not sunproof, say scientists. According to US epidemiologists Cedric and Frank Garland, though the lavish use of sun lotions blocks out the most damaging sun rays and prevents sunburn, it …
A US study refutes the notion that airline pilots nearing 60 are more likely to cause accidents than their younger colleagues. The two-year study, which analysed accident data between 1976 and 1988, was undertaken to test the validity of a US Federal Aviation Administration (FAA) rule, which bars sexagenarian pilots …
ALCOHOLIC mothers whose babies suffer from foetal alcohol syndrome (FAS) have a great deal for which to answer. Not only are such babies prone to mental retardation, but they rarely improve intellectually, even with careful parenting and education (The Lancet, Vol 341, No 8850). Hans-Ludwig Spohr and his colleagues at …
KHEJRI (Prosopis cineraria) is nature's best gift to the farmers of Rajasthan and Haryana for it not only thrives in drought conditions and in poor soils, but also encourages the growth of crops planted near it if its lateral roots are pruned (Changing Villages, Vol 12, No 1). Scientists at …
