THE World Commission on Environmental Development, 1987, gave way to the famous Brundtland Commission Report titled Our Common Future. This report, for the first time, made 'sustainability' a major international issue and gave it a much wider relevance in the process. Thus, sustainability came to be associated with equity, international …
Crippled Human Immunodeficiency Virus (HIV) could be useful in gene therapy, says Inder Verma, a gene therapy specialist at the Salk Institute in California, USA. Retroviruses, the family to which HIV belongs, are good vehicles for delivering therapeutic genes into cells of patients with genetic disorders. But while retroviruses cannot …
The discovery of plasma crystals (that are colloidal particles introduced into a charge neutral plasma) has led to several insights into the dynamics of melting and freezing. Hubertus Thomas and G Morfill of the Max-Planck Institute at Garching, Germany, have used polymer spheres of about seven micrometres diameter to study …
AGGRESSIVE behaviour and delinquency in boys may not be inherent, as is generally thought. It might also not be related to the social environment around the child- rather it could be caused due to the physical environment, A new study finds that high levels of lead in the bone might …
IT IS common, knowledge that particles like pollen, moulds, dust mites and animal dander set off asthma attacks in susceptible people, but now a new study establishes the link between food allergies and respiratory problems. The study was conducted at the Johns Hopkin Children's Centre in Baltimore, Maryland, us, where …
WHILE anti-cancer drugs kill turnout cells, healthy tissues in the patient's body cannot escape the chemical crossfire. This leads to vicious side effects that sometimes lead the doctor to halt the treatment before completion of the dosage. Scientists have now come up with a solution to this problem. A drug …
Quark, thought to be the simplest building block of nuclear matter, may contain still smaller building blocks, as suggested by scientists working at Fermilab's huge particle accelerator near Chicago in US. Some revision in the theory given by the team of scientists will be needed as the data is puzzlingly …
DUTCH researchers recently came to conclude that balloon angioplasty and not laser, is more effective in removing blockages in blood vessels connected to the heart. The finding came after a three-year study comparing the two methods by Dutch researchers. Meanwhile, another study found that the technique could also help combat …
MELATONIN gets secreted by the pineal gland, a pea-size structure at the centre of the brain. A potent hormone, melatonin is the natural nightcap. It sets the body's clock and helps it sleep. Most animals, including humans, produce a lot of melatonin early on in life but its level in …
THE liver, a dark red gland situated in the upper right side of the abdomen, performs a wide range of important functions like secretion of bile (important for the digestion of fat) and the conversion of sugars into glycogen. Due to the complex nature of the functions performed by it, …
INDIA, a frontrunner as far as the incidence of heart attacks is concerned, will have to import the technique of mending damaged hearts. The repair kit, called 'cellular bandage', meant to seal holes in the heart occuring after an attack, was recently developed by researchers in the us (New Scientist, …
'Plastic electronics', which behave like semiconductors, could become cheap, flexible alternatives to silicon-based electronics for certain products, according to Dutch scientists. These substitute semiconductors are based on polymers. Researchers at Philips have demonstrated that simple electronic circuits could be made cheaply by using low-cost substrates such as glass or plastic. …
THE 10th anniversary of the Vienna Convention, which led to the 1987 Montreal Protocol, saw more than 100 governments meet at Vienna to continue the struggle to save the ozone layer. The two-week meet led to an agreement to add two new chemicals in addition to the existing ones to …

INSECTS, today make up the vast majority of living organisms. Although insects appeared almost 350 million years ago, they really began to diversify only after flowering plants came on the scene about 150 million years ago. The catalytic role played by flowering plants in the diversification of insects stems from …

GRUESOME highway accidents are so common in India that they are routinely relegated to the inside pages of newspapers. But the month of March took, as it were, the cake (see pages 18-19): in the first, which occurred outside Muzaffarnagar in Uttar Pradesh, 22 people died of concentrated sulphuric acid …
ANIMAL drawn carts are an integral part of rural India. If you compare weight and distance ratio within a village, bullock carts are perhaps the most efficient modes of transport. No study, however, has been done to calculate the energy efficiency of this popular mode of transport. On the other …
