Good Food is First Food. It is not junk food. It is the food that connects nature and nutrition with livelihoods. This food is good for our health; it comes from the rich biodiversity of our regions; it provides employment to people. Most importantly, cooking and eating give us pleasure. …
during all of the cruise, the project scientists have been busy planning what they will investigate when the probe gets near Saturn. Their plans go into action about six months before the spacecraft's arrival at Saturn. And 19 days before arrival, a flyby past Saturn's most distant satellite, Phoebe, is …
the countdown for Cassini's launch had more than its share of the drama. For the first time in the history of space exploration, people protested against the launch of a spacecraft. Most of them were convinced that using plutonium to fuel the rockets attached to the probe was risky. Cassini …
even as commercial logging is taking a high toll of usa 's national forests, the us forest service has approved a new management plan for the great Tongass national forest in southeast Alaska. The plan awaits the approval of the agriculture secretary Dan Glickman. The plan would allow more logging …
Scientists in the US have identified a toxin produced by a strain of Bacillus thuringiensis (Bt) which could delay development of resistance to Bt pesticides by insects. Bt produces a class of toxins called CryIV. However, insects had started developing resistance to these toxins. Researchers at the University of California …
a battery-powered electronic cigarette holder, the first of its kind, is being tested in the us . The device eliminates smoke and ashes from the ends of cigarettes. Developed by us -based Philip Morris Cos, the
x-ray is an important diagnostic tool in medical science But researchers have been facing the problem of focusing these beams since ordinary lenses do not bend them. Now, J Golovchenko and C Liu at the Harvard University, usa , have used a curved wall of polished silicon to bend the …
The colour of a substance is produced when electrons in a material absorb certain wavelengths of light and jump to a higher energy state. One can change optical properties of a substance by restricting electrons from jumping up. This has up technique has uptill now worked only in gases. But …
a major breakthrough involving commercial solar power generation will make it very popular. A proposal has been made to use amorphous silicon instead of the traditional crystalline silicon in solar cells. The cheaper amorphous silicon promises to bring down the cost of power generation, the sole factor that has prevented …
Buckyballs are molecular spheres of carbon that are used in a variety of fields ranging from semiconductors to new chemicals. Now, researchers at the Washington University in St Louis, USA, have used them in a water soluble form to absorb certain nerve destroying chemicals in mice. Buckyballs helped slow down …
The Hubble Space Telescope of the National Aeronautics and Space Administration (NASA) has discovered a spectacular fireworks show of stellar birth at the heart of a pair of colliding galaxies. The recent findings may provide astronomers a unique opportunity to study the stellar formation produced by a catastrophic event in …
studies reveal that a comet crashed into the Earth 370 million years ago, blasting a huge crater into the sea floor. Charles Sandberg, a geologist emeritus with the us Geological Survey, says this triggered 304 m waves that resulted in the extinction of many species. He feels that the crash …
Most people would have heard about the mythical disappearance of Atlantis. Even researchers believe that the ancient Iapetus Ocean never existed at all. However, Warren Huff, a geologist at the University of Cincinnati, USA, has found evidence of a narrow Iapetus Ocean from ancient volcanic ash beds. He says that …
diabetes patients may not require to take painful insulin injections to regulate their blood sugar levels. Researchers at Eli Lilly & Co, usa , have developed a method so that patients would merely have to breathe insulin for it to reach the targeted part of the body. The process involves …
researchers have concluded after analysing a 30-year research on possible links between coffee/caffeine consumption and coronary heart disease and hypertension that it does not have any long-term effect on human health. They say there is no medical basis for urging people to give up coffee, beverages and other foods containing …
a protein has been found in the body's main weight-regulating system that could be targeted to develop obesity drugs. Gregory Barsh and his colleagues at Standford University School of Medicine, California, usa, have named the protein as aguoti-related protein ( agrp ). In 1994, researchers had discovered leptin, a protein …
According to a US surgeon, Robert White, human heads can be surgically transplanted on to healthy bodies of dead donors. White who has experimented with animals, has already achieved success in head transplantation of rhesus monkeys. He says that in future, a person with a healthy head, but broken body …
Contrary to popular belief that red wine is more cardio-protective than white wine or beer, a study suggests that all of them have equal presumptive health benefits. Gary Friedman and his colleagues at the Kaiser Permanente Medical Centre, Oakland, USA, have reached the conclusion after studying 42,306 men and 39,519 …
a group of activists and health professionals in the us have offered to test a controversial aids vaccine on themselves. Their offer is a part of a calculated effort to break the deadlock that has frustrated researchers since the start of the aids epidemic. Scientists know vaccines are the best …
