A new computerized scan of the biomedical research literature has turned up tens of thousands of articles in which entire passages appear to have been lifted from other papers. Researchers estimate that there may be as many as 200,000 duplicates among some 17 million papers in leading research database Medline.
A young star speeding away from the Milky Way is in fact an alien visitor, astronomers have confirmed. The wayward object is one of several rogues that are giving astronomers a glimpse into the volatile nature of our galaxy and others.
Scientists are chafing at the U.S. government’s unfulfilled pledge to boost funding for basic scientific research, the source of innovations ranging from the World Wide Web to high-tech cancer treatments.
In a feat of optical alchemy a postdoctoral researcher uses ultrashort laser bursts to pockmark the surface of a metal in a way that is not perceptible to the touch.
Astronomers at the University of St Andrews believe they can “simplify the dark side of the universe” by shedding new light on two of its mysterious constituents.
Astronomers have used ESO’s Very Large Telescope to measure the distribution and motions of thousands of galaxies in the distant Universe.
The photos reveal widespread volcanic activity, asteroid assaults, and a spider-shaped formation the likes of which have never before been seen in the solar system.
Fifty years ago today, the 70-foot (21-meter) tall Juno 1 rocket, a modified Redstone missile, launched the Explorer I satellite, marking the first U.S. built payload to enter Earth orbit.
There are some discussions about the recent applications on photonic nanolasers and photonic integrated circuits based on photonic crystals.
Newly designed solar cells can be screen-printed in a wide array of colors and patterns to allow them to be attractively incorporated into building design.
The A2 is designed to carry up to 300 passengers from Brussels to Sydney in under 4 hours. The speedy airliner will benefit from a 2-mode engine ? turbojet and ramjet propulsion systems ? that will make it both extremely efficient at slow speeds and able to reach top speeds with great ease.
A large US spy satellite has gone out of control and is expected to crash to Earth some time in late February or March. Officials said the satellite had lost power and propulsion, and could contain hazardous materials.
Squarks, selectrons, neutralinos. A few types of supersymmetric particles, a special particle that may be created when the world’s most powerful atom smasher goes online this spring.
Researchers have produced a laser beam of especially high quality. In doing so, they have achieved a new world record in the control of photons by precisely placing the photons in a specific order.
ESA?s orbiting gamma-ray observatory, Integral, has made the first unambiguous discovery of highly energetic X-rays coming from a galaxy cluster.
