A team from the Korea Advanced Institute of Science and Technology have found the cause of resistance to an anti-tumor drug, which may open new possibilities for cancer treatment.The scientists used computer simulations and mathematical biology to investigate the cause of the drug resistance. They discovered that cell signaling ― how cells communicate and respond to their environment ― plays an important role in the mechanism.The study, supported by the Ministry of Education, Science and Technol

(MCT)Researchers say they've found evidence of an extraterrestrial impact on Earth 13,000 years ago that may have been involved in a major life extinction event.An international team of scientists says melted glass material in a thin layer of sedimentary rock in Pennsylvania and South Carolina, and in Syria, was formed at temperatures of 3,100 to 3,600 degrees Fahrenheit and is the result of a cos

He risked freezing or starving to death on a doomed expedition to the South Pole 100 years ago -- but for George Murray Levick, the real horror lay in the twisted sexual mores of the Adelie penguin.London's Natural History Museum has unearthed a landmark study by Levick, a scientist with the ill-fated 1910-13 Scott Antarctic Expedition, detailing the birds' sexual shenanigans, the Guardian newspap

 Dogs respond to a person who is crying regardless of whether it is their owner or an unfamiliar person, researchers in Britain found.Dr. Deborah Custance and Jennifer Mayer, both of the Department of Psychology at the University of London, developed a procedure to examine whether domestic dogs could identify and respond to emotional states in humans.Eighteen pet dogs -- a range of ages and breeds

NASA says its Spitzer space telescope has detected the faint glow of the very first objects in the universe with the best precision yet.The faint objects, which might be incredibly massive stars or voracious black holes, are too far away to be seen individually but Spitzer has captured convincing evidence of what appears to be the patterns of their infrared light, NASA's Jet Propulsion Laboratory

 A top U.S. nanotechnology expert called for greater collaboration among countries and disciplines to deliver its potential to revolutionize computing, electronics, medicine, energy, environment and even agriculture.Nanotechnology is a fast-developing field of engineering that deals with manipulating materials of atomic and molecular size. One nanometer is one-billionth of a meter. The technology is finding its way into an increasingly wider range of industries with the convergence of diverse fi

Italian archeologists discovered last month a skeleton believed to have been part of an exorcism ritual, providing clues to how vampire myths became popular around the world, the Daily Mail reported.The skeleton, found in a mass grave on the island of Lozzarretto Nuovo in Venice, was buried with a brick jammed in its jaws. It is believed that whoever buried the woman suspected her of being a vampire. Placing a brick in a vampire-suspect’s mouth was a tradition during the middle ages to ensure th

(Viet Nam News)Two people in southern Vinh Long Province caught a 1.7-meter long dragon fish weighing nearly 50 kilos in the Hau River, near the Ninh Kieu pier in Can Tho City on Wednesday.After catching the fish, they killed it and prepared it for sale, not thinking to preserve it as an ornamental trophy.The dragon fish was subsequently buried in Ba Chua Xu Temple yesterday, attracting large crow

(AFP)British scientists say their new technique to accurately measure the weight and size of dinosaurs shows they were not as heavy as previously thought.University of Manchester biologists used lasers to determine the minimum amount of skin required to wrap around the skeletons of modern-day mammals, then applied the technique to a giant Brachiosaur skeleton in a Berlin museum.While previous esti

U.S. scientists have found that the evolution of birds may have triggered the extinction of gigantic insects, according to a report on Proceedings of the National Academy of Sciences.Researchers from the University of California, Santa Cruz studied the fossil records dating back to Carboniferous period, and found that high oxygen levels of the time allowed species like dragonfly-like Meganisoptera to have wingspans of up to 71 centimeters around 300 million years ago. Further study showed that m

From the movie “A Beautiful Mind” to television drama “House M.D.,” the notion of the psychotic genius has always been popular to public audiences. However, scientists with a history of various mental conditions themselves have suggested that there is an actual correlation between being mentally ill and being smart, according to an article on the website Livescience.In the report, a group of panelists at the annual World Science Festival in New York on Thursday said that a previous study in 2010
