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 …
The hottest volcanoes of the solar system are situated on Io, a moon of Jupiter. Latest images of the volcanoes may help scientists to investigate Io's most active volcanoes, Prometheus . The volcano appears to have shuffled about 80 km across the moon's surface in the past two decades. Alfred …
Arecibo, the world's most powerful radar and radio telescope, has been upgraded with new instruments. It has a 305-metre dish that is placed in the crater of an extinct volcano in Puerto Rico. Arecibo has been fitted with a dual-mirror system to collect and focus signals that come from the …
Mathilde, a 52 kilometres asteroid, has been observed by the Near Earth Asteroid Rendezvous (NEAR) spacecraft. The spacecraft measured the mass of the asteroid when it passed within 1,200 km of Mathilde. Findings show that Mathilde is full of cavities. Researchers at the Jet Propulsion Lab, Pasadena, USA, say the …
a huge bubble of hot and magnetically charged gas has been discovered that may damage satellites after reaching the Earth's atmosphere. The bubble in the form of a giant cloud travels towards the Earth with a speed of 14,48,100 km per hour. When it reaches the Earth, the bubble expands …
companies such as ibm have now switched over to a new technique of scattering a thin film of magnetic molecules on the surface of the disk, as this helps increase drive capacity. Earlier, the engineers were using the old technology of embedding iron particles into the plastic of the disk. …
a strain of bacteria has won devotees among mathematicians, engineers and physists due to its several applications. A mutant form of a common, rod-shaped bacterium, Bacillus subtilis was discovered in 1975 by Neil Mendelson, a microbiologist of University of Arizona, usa. Today, it is being used by scientists to develop …
a light emitting device developed by researchers at the University of Surrey, uk , may pave the way for a cheaper and more sophisticated optoelectronic devices. Optoelectronics - the combination of electronic and optical functions - is an area which has tremendous applications in communications industry. From compact disks to …
the magnetic field of a star has been mapped for the first time by a team of researchers at the National Radio Astronomy Observatory, usa . The team led by Kemball and P Diamond has mapped the magnetic field of tx Camelopardalis ( tx Cam), a red giant star about …
the efforts to monitor the world's changing climate from space received a major jolt on June 30 when National Space Development Agency ( nasda ), the Japanese space agency, lost connection with its Advanced Earth Observing Satellite ( adeos ). The agency has also lost a set of vital climate …
If a comet merely ten-thousandth the size of Hale-Bopp strikes the Earth, it would create an explosion ten times as powerful as all the nuclear weapons in existence at the height of the Cold War, according to a supercomputer simulation. David Crawford of Sandia National Laboratories, Livermore, California, has modelled …
Plans are being finalised for the world's largest radio telescope by astronomers from India, Australia, Canada and three other countries. The telescope
The latest findings of the spacecraft Galileo, which has been providing valuable information about Jupiter and its satellites, relate to moon Callisto. The satellite shows no evidence of an internal magnetic field and is unlike the other satellites of Jupiter such as Io, Europa and Ganymede. In other satellites, the …
stars , apart from emitting visible light, also emit radiation in the other regions of the electromagnetic spectrum. There are stars which primarily give out visible light, like our Sun, or those which give out most of their energy in the form of radio waves or x -rays. The Sun …
when it comes to building new structures, human ingenuity is no match for nature, especially living cells. Even at the simplest level, molecules assemble into amino acids, then into proteins, which in turn form a variety of different structures. But now, with the work of Samuel Stupp of the University …
the information superhighway has brought with it the need for fast and reliable communication channels. The old telephone cables cannot supply the bandwidth required for applications like multimedia or video conferencing. Optical fibres have truly revolutionised communications in the last few years. But there are potholes on this information highway. …
though superconductivity was discovered by the Dutch physicist Heike Kamerlingh Onnes about 85 years ago, it remains an enigma in many ways. The discovery of high temperature superconductivity and the numerous potential applications, from more powerful particle accelerators to high speed trains have been responsible for the enormous amount of …
cosmology and astrophysics are two sciences where the scientist has to be content with mere observation, since the researcher has no control over the experimental arena. But recent work in various laboratories has provided astrophysicists with a unique opportunity to study and
An ultraviolet, chip-based laser has been developed by Japanese scientists recently. Reports say that it is the shortest wavelength laser to be devised ever. This finding means that compact discs could be loaded with far more information than is thought to be possible at present. The device, developed by M …
Bruce Railsback of Georgia University, Athens, USA, has concluded that lightning increases the acidity in rain. This was discovered while studying the change in the acidity of rainfall during a storm. Railsback gathered 132 samples of falling rain at intervals of 90 seconds in north-eastern Georgia. Samples collected while thunder …
Scientists at the Lawrence Berkeley Laboratory, California, have announced the fabrication of the worlds' strongest magnet. The new magnet creates a field of 13.5 tesla which beats the previous record of 11 tesla. The seven-tonne magnet comprises a superconducting alloy of niobium and tin, which is put into copper cable. …
