NASA's Gravity Probe B spacecraft could begin testing Einstein's general theory of relativity as early as this week, according to mission controllers at Stanford University.
Acid rain restricts global warming by reducing methane emissions from natural wetland areas, suggests a global climate study.
Acid rain is the result of industrial pollution, which causes rainwater to carry small quantities of acidic compounds such as sulphuric and nitric acid. Contaminated rainwater can upset rivers and lakes, killing fish and other organisms and also damage plants, trees and buildings.
WASHINGTON - California scientists say they have created the first synthetic version of a rogue protein called a prion and used it to give mice a brain-destroying infection, evidence important to settling any lingering doubt these mysterious substances alone cause mad cow disease and similar illnesses.The report, published Thursday, won’t end the scientific controversy, as skeptics already are criticizing the research. But if the work ultimately is validated it could have far-reaching implications — such as helping to create diagnostic tests for mad cow disease.
LONDON (Reuters) - Nanotechnology -- which operates on an almost unimaginably small scale -- offers tremendous potential, but regulation is needed to minimize any future risks, scientists said on Thursday. The atom-sized technology could lead to more powerful computers, very light but strong materials and advanced medical techniques. But a report by the Britain's Royal Society, an academy of leading scientists, and the Royal Academy of Engineering, said more research is needed to discover any negative, as well as positive effects, it may have.
If intelligent life exists elsewhere in our galaxy, advances in computer processing power and radio telescope technology will ensure we detect their transmissions within two decades. That is the bold prediction from a leading light at the Search for Extraterrestrial Intelligence Institute in Mountain View, California.
Seth Shostak, the SETI Institute's senior astronomer, based his prediction on accepted assumptions about the likelihood of alien civilisations existing, combined with projected increases in computing power.
