[:es]Newfound brain structure explains why some birds are so smart—and maybe even self-aware[:]
[:es]Never before has “bird brain” been such a compliment: In recent years, birds have been found to make tools, understand abstract concepts, and even recognize paintings by Monet and Picasso. But their lack of a neocortex—the area of the mammalian brain where working memory, planning, and problem solving happen—has long puzzled scientists. Now, researchers have…

[:es]Brain-scanning backpack brings neuroscience into the real world[:]
[:es]Call it neuroscience on the go. Scientists have developed a backpack that tracks and stimulates brain activity as people go about their daily lives. The advance could allow researchers to get a sense of how the brain works outside of a laboratory—and how to monitor diseases such as Parkinson’s and post-traumatic stress disorder in real-world…

[:es]‘Viking’ was a job description, not a matter of heredity, massive ancient DNA study shows[:]
[:es]It was a Viking saga written in genes. In 2008, construction work on an isolated Estonian beach near the town of Salme uncovered the skeletons of more than 40 powerfully built men. They were buried around 750 C.E. in two ships with Viking-style weapons and treasure—apparently the aftermath of a raid gone wrong. DNA from…

[:es]Deep beneath the high seas, researchers find rich coral oases[:]
[:es]Aiming to bolster conservation on the high seas, a team of marine researchers today released the first comprehensive survey of coral reefs in the high seas–the roughly two-thirds of the ocean outside of national jurisdictions.[:]

[:es]One of quantum physics’ greatest paradoxes may have lost its leading explanation [:]
[:es]It’s one of the oddest tenets of quantum theory: a particle can be in two places at once—yet we only ever see it here or there. Textbooks state that the act of observing the particle “collapses” it, such that it appears at random in only one of its two locations. But physicists quarrel over why…

[:es]Warrior skeletons reveal Bronze Age Europeans couldn’t drink milk [:]
[:es]About 3000 years ago, thousands of warriors fought on the banks of the Tollense river in northern Germany. They wielded weapons of wood, stone, and bronze to deadly effect: Over the past decade, archaeologists have unearthed the skeletal remains of hundreds of people buried in marshy soil. It’s one of the largest prehistoric conflicts ever…

[:es]Watch levitating upside-down boats flip the law of buoyancy[:]
[:es]If you’re a water sports fan looking for a new thrill, what about upside-down sailing? The idea might not be so outlandish. In a new study, physicists have managed to float tiny boats on the underside of a layer of liquid levitating in midair (see animation, above). Besides opening up some unusual nautical possibilities, the…

[:es]Some mosquitoes already have resistance to the latest weapon against malaria[:]
[:es]An insecticide about to be widely deployed inside African homes to combat malaria-carrying mosquitoes is already losing its punch. Two years ago, the World Health Organization (WHO) gave the green light for clothianidin, long used in agriculture to kill crop pests, to be added to the current mainstays of indoor mosquito control, which are losing…
