NUCLEAR FUSION/ACOUSTIC CAVITATION Emissions from collapsing bubbles The study suggests that high temperatures and pressures within the bubbles would be sufficient to generate nuclear fusion in the bubbles' collapse. More 
T-rex was probably a slow runnerRESEARCHERS HAVE calculated how much leg muscle a land animal would need to support running fast using principles of biomechanics. John Hutchinson of Stanford, of with Mariano Garcia, now of Borg-Warner Automotive created a computer model to ... More Self-repairing plastic A TEAM of chemists and engineers has developed a transparent plastic that if fractured will mend itself when heated — a discovery that can be used to create self-repairing products. The findings by the university of California-Los Angeles ... More Moderately stable triplet carbene A RAGING lion of the chemical world has been tamed. Japanese chemists have made a moderately stable `triplet carbene', a type of free radical that's normally extremely reactive and short-lived. The carbene lives for nearly half an hour and ... More Setting micro gears in motion THE MOVEMENT of gears and motors in micromachines just got easier because of the lateral Casimir force. This force acts tangential to two surfaces, resulting in a horizontal sliding motion of one surface against the other. The University of ... More Aqua satellite NASA's AQUA spacecraft is ready to ship to Vandenberg Air Force Base, California. To begin launch preparations. Aqua will undergo final tests and integration with a Delta II rocket for launch in April. It is the latest in the Earth Observing ... More Earth's magnetic field did reverse RESEARCHERS HAVE developed an improved method of identifying magnetic signals in old geological strata and have used the new method to show that the Earth's magnetic field really did reverse itself 10 million years ago. Particles of iron in ... More NANOTECHNOLOGY/ELECTRODES AND NANOPROBES PAVE WAY Simplified DNA detection Pairing of microelectrodes and gold nanoparticle probes simplifies DNA detection and could lead to a handheld device that is accurate, less expensive and faster than conventional methods. More Inhibiting cardiac proteins BLOCKING A key protein involved in calcium regulation can improve the function of failing heart cells, according to a study in the journal Circulation. ``We set out to inhibit a protein that blocks normal calcium flow in the heart," says ... More Fractals to measure natural disasters EARTH SCIENTISTS are now able to forecast natural disasters such as hurricanes, floods, earthquakes and volcanic eruptions using fractals. It is a mathematical formula of a pattern that repeats over a wide range of size and time scales. These ... More Reducing costs in ceramic manufacture INDIA IS capable of producing ceramic products to compete with developed countries in quality. But, the main constraint is consistently producing high quality yields. This is due to inconsistency in quality of input raw materials. Adequate ... More Going round the bend A GOOD memory and careful posture are the key to powering around bends at 200 kilometres per hour, a study of a racing driver has revealed, according to a report in New Scientist. When negotiating a bend, ordinary drivers fix their eyes ... More Stems and leaves proportional to roots ADD THIS universal truth to all the biology textbooks: the mass of a plant's leaves and stems is very much proportionally scaled to that of its roots in a mathematically predictable way, regardless of species or habitat. In other words, ... More
IT USED to be said that dead men tell no tales. It was on the belief in this saying that the underworld `took out' people who could have divulged sensitive information to the police and the court. This belief may well hold with regard to what the ... More
