In India, a country with a vast population and a diverse socio-economic fabric, healthcare remains fraught with challenges including disparities in access. These socio-economic disparities are deep, and they influence health outcomes. It is imperative to bridge these gaps amid the ongoing epidemiological, nutritional and demographic transitions that are bringing …
more than half of all tumour cells contain tiny extra chromosomes that encourage the cancer to grow. Now scientists may finally be able to find a way to obviate cells of the excess dna , using a technique that lets them watch these chromosomes at work in living cells. Called …
THE Spanish Conquistadors came to the New World in search of gold. They found tobacco instead, a cash crop which sold better than any other in history. It became a legal narcotic, the foundation of many a business empire. It also became a scourge let loose by the New World …

this is where physics meets medicine. The science of particle beams may be quite beyond the limits of medical science, but the two might soon collaborate, with results that may surprise many doctors (of medicine, that is). Two new research programmes in Europe have begun exploring down-to-earth uses for two …
the controversy has been raging ever since cellular telephones invaded our lives. These gadgets heat up your brain, meddle with your pacemakers and perhaps, cause cancer. And ever since these words of doom were uttered, scientists have been looking at the connection of these adverse health effects with the increasing …
a chance discovery that a stingy little invertebrate is not always what is seems will soon help in the development of a promising new anticancer drug. Researchers in California have discovered why some populations of Bugula neritina ( B neritina ), a marine fouling organism, produce the drug but others …
Sunscreens do not help prevent skin cancer. This startling revelation came recently at a science conference in Philadelphia, USA, where the widely-held belief that sunscreens lower the risk of deadly melanoma skin cancer was questioned. Sunscreens prevent sunburns, and since there is evidence that frequent burns, especially at an early …
Low-tar, filter-tipped cigarettes have only increased the incidence of adenocarcinomas, a cancer occurring deep inside the lungs. According to the American Cancer Society, only non-filtered cigarettes were linked to lung cancers so far.

seaweed found on beaches across Britain may provide some important clues to scientists about the process through which cancer develops. Researchers at the University of West of England, Bristol, have discovered a technique to track the growth of deadly cancer cells in the body using a seaweed extract. The researchers …
Garlic protects against disease-causing micro-organisms. But till recently, no one knew how it performs the germ-killing function. David Mirelman of the Wiezmann Institute of Science, Rehovot, Israel, has discovered that garlic contains a peptide called allicin which attacks proteins rich with amino acids. When the researcher exposed Entamoeba histolytica parasites …
scottish researchers have developed a heat-sensitive bra with an electronic memory chip that can successfully detect premenopausal breast cancer. The Chronobra was developed by Hugh W. Simpson, pathologist at the Royal Infirmary at Glasgow, who claims that it can be an alternative to Mammography. Simpson speculates that the breast temperature …
standing on a reforested hill, flush with the first gossamer green buds of spring, Stanislav Stys, an expert on land reclamation, gazes out across the city of Most in northern Bohemia, the Czech Republic. European blackbirds rummage through the forest litter for tasty insects, while overhead in the leafy canopy, …

According to Bangkok gemologists, hundreds of dangerously radio-active gemstones are circulating in the Asian markets and some have even found their way into finished jewellery. Tests conducted by radiologists in the Thai capital have revealed radiation levels in some stones were more than 50 times the us safety limit. Experts …
The Indian Council of Medical Research (ICMR) is preparing a new set of guidelines to deal with the "ethics and informed consent" in drug and genetic tests on people. The draft - Statement of principles on medical and genetic research on human subjects - prepared by a committee headed by …
Gemologists in Bangkok say that hundreds of dangerously radioactive gemstones are circulating in Asian markets and some of them have found their way into finished jewellery.
