Giant dinosaurs that roamed the Earth millions of years ago may have warmed the planet with the gas they produced from eating leafy plants, British scientists said on Monday. (AFP-Yonhap News)Much like modern cows that emit a significant amount of methane in their digestive process, the 20,000 kilogram sauropods contributed the same way, and likely more, to the warming climate, said the study in t

A super-full and extra-bright moon dazzled the night skies this weekend as the lunar body swept along the low point of its elliptical orbit around the Earth. The Super Moon is shown after rising over Canton, Ohio, Saturday. (AP-Yonhap News)The so-called lunar perigree brings the moon about 50,000 kilometers closer to the Earth than when it's at the farthest point of its oval orbit.When a full moon

`UFO`s sighted over Tennessee, United States (YouTube)Multiple UFO sightings have startled people around the world, according to news reports.Over a six-day period, four reports emerged: one in the United Kingdom, one in Australia and two in the United States.The first sighting took place last Thursday when a passenger on an airplane in the U.K. reportedly videotaped what looked like three UFOs fl

A French American scientist has developed a new alcohol spray that can intoxicate the user instantly, a U.S. news report said. According to the report, however, the spray’s effects last only moments.David Edwards created the spray called “WA|HH Quantum Sensations” and unveiled it during an exhibition in Paris, the report said.The spray is contained in a finger-long bottle, designed by French product designer Philippe Starck.It will be sold for about $26, the report said.(yoonmi@heraldm.com)<관련 한

Some dinosaurs may have been on the way to extinction millions of years before an asteroid hit the Earth 65 million years ago, U.S. researchers say.Chicago White Sox pitcher Mark Buerhle has a chuckle with robotic "Baby T Rex," who threw out the first pitch before the game against the Detroit Tigers at at U.S. Cellular Field in Chicago, Illinois, Wednesday, August 6, 2008.

Korean scientists succeeded in cutting a damaged strand of DNA with engineered nuclease technology, or a “molecular scissors,” without generating mutation. The progress in gene editing is expected to help increase the effectiveness of gene therapy which in most cases fails to achieve intended results, said Kim Jin-soo, a chemistry professor at Seoul National University, who led the research. His team was able to prevent mutation with a new DNA-cutting enzyme that cuts only one DNA strand entwine

A pair of pigeons touch beaks at an exhibit at a zoo, Thursday, April 26, 2012. (AP)Pigeons navigate by recording information about Earth’s magnetic field, using certain brain cells as a sort of biological compass, U.S. scientists say.The finding gives insight into how many birds can migrate thousands of miles, flying day and night, even when the sun or stars are obscured by clouds, the researcher

Russian scientists said that 76 types of micro-organisms have been causing “severe damage” to the International Space Station, according to Interfax news agency and other local news reports.(MCT)“We had these problems on the old MIR space station, now we have them on the ISS. The microflora is attacking the station. These organisms corrode metals and polymers and can cause equipment to fail,” Anat

British scientists have identified genes that are flicked on and off in the course of the aging process, marking a breakthrough for anti-aging research, Science Daily reported Thursday.The epigenetic changes in four genes related to cholesterol, lung function and maternal longevity seemed to have a significant impact on aging and longevity, researchers at King’s College London and Wellcome Trust Sanger Institute found. Epigenetic refers to hereditary genetic modifications that do not change unde
