Order of the National Green Tribunal in the matter of In Re: News Item titled "Nayar river is vanishing - a yatra reveals conservation goes beyond science and policy" appearing in ‘The Down To Earth’ dated 03.06.2025. The original application was registered suo-motu based on the news item titled "Nayar …
Oxygen has been discussed in the moon's atmosphere by a team of German researchers. The team from the Max Planck Institute for Aeronomy in Katlenburg-Lindau used data fron a nearby Nasa satellite to study the thin luner atmosphere and found traces of oxygen, silicon and aluminium.
The moon contains water that is theoretically enough for thousands of humans to live there, according to a new study. Data collected by Nasa's unmanned lunar prospector "Probe" has enabled scientists to estimate the existence of some three billin metric tonnes of water ice on each pole of the moon.
Physicists at Stanford have developed a new optical detector so sensitive that it can clock the arrival of a single particle of light and measure its energy with exceptional precision. When applied to light coming from celsetial objects, the device's ability to directly measure the location, arrival time, and energy …
British scientists are hoping to land an instrument on Mars that will "sniff" the presence of life. Beagle 2--the name evokes Charles Darwin's world-changing voyage aboard HMS Beagle in 1831 --could be launched aboard a European mission called Mars Express in 2003.
The left handed molecules that led to the beginning of life on Earth may have been singled out for their eventual role in biology by a type of radiation that astronomers have discovered in a star-forming cloud about 1,500 light years away. A team of astronomers in Australia reported in …
Russian officials have defied their US partners on the International Space Station project by insisting that their own crippled and seemingly jinxed Mir lasts into the next century. They want their ageing spacecraft to be spared a splashdown end in the Pacific Ocean next year.
if you want to become a better tennis player these tips would certainly prove handful. Now Rod Cross, a physicist at the University of Sydney, Australia, has found that it is not a bouncy spot but a dead spot on the racket from where the powerful serves come from ( …
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 …
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 …
A theory of how the moon was formed is at stake. Robin Canup and her colleagues at the University of Colorado, USA, say if a collision between the Earth and a planet-sized body would have led to formation of the moon, the Earth and moon should have more angular momentum …
Tiny nanotubes (a billionth part of a tube) can be used to make materials with fewer defects compared to their larger counterparts. E W Wong and his colleagues at Harvard University, Cambridge, UK, have explored the strength of nanotubes. They determined mechanical properties of nanorods and carbon nanotubes. It was …
An analysis of data from the Halogen Occultation Experiment (HALOE) on the Upper Atmosphere Research Satellite indicates that there is a wet layer about 70 to 80 km up. It is generally believed that water vapour in the atmosphere is trapped below 12 km while the region between 50 and …
a cluster of galaxies has been found that looks bright in the x -rays region but contains only a single visible galaxy. A team led by M Hattori at the Max-Plank-Institut fur extraterrestrische Physik, Giessenbachstrasse, Germany, reports that it is the most distant cluster of galaxies in the x -rays …
a solid lubricant has been developed in Israel that does not lose its lubrication properties even in humid conditions. R Tenne and his colleagues, at the Department of Mechanics and Control, Centre for Technological Education, Holon and Department of Materials and Interfaces and Chemical Services Unit, Weizmann Institute, Rehovot, synthesised …
the Compton Gamma Ray Observatory based at the National Aeronautics and Space Administration ( nasa ), usa, has detected that gamma-ray bursts occur almost every day. The flashes appear from random directions and last for a few seconds. There are two theories on gamma-ray bursts. One theory suggests that the …
the Achilles heel of optical fibre transmission has always been electronic switches that act as speed breakers to the flow of information. But Sergey Frolov and Valy Vardney of the University of Utah, Salt Lake City, have now developed optical switches that would enable data transmission at a high speed …
