[:eu]Buried lasers will sense Earth’s spin and quakes doing the twist[:]
[:eu]The aluminum hatches are the only clue to what lies beneath. Buried amid the corn and wheat fields of Fürstenfeldbruck, a sleepy monastery village 20 kilometers from Munich, Germany, is an inverted pyramid of concrete, steel pipes, and precision sensors, as deep as a three-story building. Last month, when lasers began coursing around the edges…

[:eu]Physicists detect whiff of new particle at the Large Hadron Collider[:]
[:eu]For decades, particle physicists have yearned for physics beyond their tried-and-true standard model. Now, they are finding signs of something unexpected at the Large Hadron Collider (LHC), the world’s biggest atom smasher at CERN, the European particle physics laboratory near Geneva, Switzerland. The hints come not from the LHC’s two large detectors, which have yielded…

[:eu]Unique Canadian ice core collection suffers catastrophic meltdown[:]
[:eu]A precious collection of ice cores from the Canadian Arctic has suffered a catastrophic meltdown. A freezer failure at a cold storage facility in Edmonton run by the University of Alberta (UA) caused 180 of the meter-long ice cylinders to melt, depriving scientists of some of the oldest records of climate change in Canada’s far…

[:eu]Weird sterile neutrinos may not exist, suggest new data from nuclear reactors[:]
[:eu]For decades, physicists have known that particles called neutrinos, which have almost no mass and barely interact with other matter, come in three types—electron, muon, and tau. And for just as long, some theorists have argued that there could exist a fourth, sterile neutrino that would be even weirder and more inert than its familiar…

[:eu]Is dark energy an illusion?[:]
[:eu]For the past 20 years, physicists have known that the expansion of the universe is accelerating, as if some bizarre “dark energy” is blowing up space like a balloon. In fact, cosmologists’ well-tested standard model assumes that 69% of the content of the universe is dark energy. However, there may be no need for the…

[:eu]Are gravitational waves kicking this black hole out of its galaxy?[:]
[:eu]Astronomers have just spied a black hole with a mass one billion times the Sun’s hurtling toward our galaxy. But scientists aren’t worried about it making contact: It’s some 8 billion light-years away from Earth and traveling at less than 1% the speed of light. Instead, they’re wondering how it got the boot from its…

[:eu]World’s lakes are much shallower than thought, mathematical analysis suggests[:]
[:eu]If lakes are shallower, they would release more methane into the atmosphere than previously estimated.[:]

[:eu]It wasn’t just Greece: Archaeologists find early democratic societies in the Americas[:]
[:eu]Tlaxcallan is one of several premodern societies around the world that archaeologists believe were organized collectively, where rulers shared power and commoners had a say in the government that presided over their lives.[:]

[:eu]Toddler play may give clues to sexual orientation[:]
[:eu]The objects and people children play with as early as toddlerhood may provide clues to their eventual sexual orientation, reveals the largest study of its kind. The investigation, which tracked more than 4500 kids over the first 15 years of their lives, seeks to answer one of the most controversial questions in the social sciences,…
