Superconducting technology is being used in the US to improve noise performance and voice quality of cellular phones. A US-based company, Ameritech Cellular Services, has reported excellent results from the use of a cellular system radio-frequency filter that incorporates superconducting devices. The use of the filter at the cell site …
Although considerable progress has been made towards the complete eradication of polio by the year 2000, the fact remains that polio cannot be eliminated anywhere unless it is eliminated everywhere. Of the 213 countries under surveillence, 145 reported zero cases in 1993. There is no doubt that polio can become …
a virus attacks a bacterium and turns the microbe into a lethal organism. The toxin that the cholera causing bacteria Vibrio cholerae produces, is in fact secreted by a virus that rides the bacterium in order to gain an entry into the cells. This startling discovery has been made by …
National Aeronautics and Space Administration's Langley Research Centre and Accurate Automation of Tennessee, US are designing a 23-foot-long subsonic flyer model of a Mach 5
Transport is an essential human activity and has a critical role in social development. But the environmental costs of this energy-intensive sector are also critical. It generates 20 per cent of anthropogenic greenhouse gas emissions and has a significant impact on the surrounding eco-systems. While all modes of transport have …
Antarctic krills, small shrimplike creatures, have adopted special mechanisms to avoid turbulence. According to Konard Welse, a zoologist at the University of Hamburg, Germany, their antennae pick up pressure waves from their neighbours for maintaining contact among themselves. After placing a small pressure sensor near the swimmerets of a krill, …
Ants, who else! Fire ants were believed to communicate mainly through pheromones -chemical signalling messages. Researchers also knew that the insects made sounds, whose function they were unclear about, by moving the abdomen up and down. Robert Hickling and colleagues from the University of Mississippi, US, have now recorded the …
OBESE women are more than twice as likely to have babies with neural tube defects (NTO) such as spina bifida, as women of average weight, say American researchers. But the two teams of researchers from Boston and California also pointout that they do not yet understand why extra fat should …
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, …
