The fact that land-bound dinosaurs laid eggs is what sealed their fate of mass extinction millions of years ago while live birthing mammals went on to thrive, scientists said Wednesday. In a new explanation for mammals’ evolutionary victory over dinosaurs, researchers said a mathematical model has shown that infant size was the clincher. Given physical limitations to egg size, dinosaurs had com...

But the U.S. remains ill-equipped for large-scale Arctic missions, according to a simulation conducted by the U.S. Naval War College. A summary released last month found the Navy is “inadequately prepared to conduct sustained maritime operations in the Arctic’’ because it lacks ships able to operate in or near Arctic ice, support facilities and adequate communications. “The findings indicate the...

Public Admission The missile reached an altitude of 151 kilometers (93 miles) before disintegrating into 20 pieces and falling into the ocean 100 to 150 kilometers off the western coast, South Korean Major General Shin Won Sik said in Seoul. North Korea state- run Korean Central News Agency said scientists are now looking into the cause of the failure. The rare public admission contrasted with ...

Scientists have concluded from reviewing data of 1976 Mars Viking rovers that bacteria existed on Mars. The original consensus of scientists has been that the experiment found geological, not biological activity. But the new study took a different, purely numerical approach. Researchers took the hard copy Viking Labeled Release data into sets of numbers and analyzed the results for complexity, ...

“A blue dress with orange pockets? It’s the Mets. And I will never do a black dress with orange pockets _ Halloween, or yellow, because that’s a bumblebee. But no sports team is going to do acid green or purple with black unless they’re the coolest team in the world,” Perry says. Sometimes she’ll use gray as the binding neutral color, especially with turquoise or hot pink which have a little bit...

The U.S. Coast Guard unleashed cannon fire Thursday at a Japanese vessel set adrift by last year's tsunami, stopping the ship's long, lonely voyage across the Pacific Ocean. A Coast Guard cutter fired on the abandoned 164-foot (50-meter) Ryou-Un Maru in the waters of the Gulf of Alaska and more than 150 miles (240 kilometers) from land, spokesman Paul Webb said. Soon after the cannon fire start...
