The Atlantic’s Natalie Wolchover writes that MIT physicists have presented a demonstration of quantum entanglement, addressing a loophole in quantum theory. Prof. Andrew Friedman says his team will continue testing the loophole, explaining, “either we close the loophole more…or we see something that could point toward new physics.”
Using data on “subatomic particles called neutrinos” from Antarctica’s IceCube Neutrino Observatory, a team including MIT researchers has determined that Einstein’s theory of special relativity is correct. “Neutrinos had not yet been discovered when Einstein died, but his theory still predicts their behavior,” explains Kimberly Hickok for LiveScience.
A team including MIT research scientist Ulrich Faul has discovered that the Earth’s interior contains 1,000 times more diamonds than was previously thought, writes Sarah Emerson for Motherboard. The researchers believe that one to two percent of “craton roots,” which are the deepest sections of the “rock layers extending upwards of 200 miles through the Earth’s crust and mantle,” may contain diamonds.
MIT researchers have discovered a cache of diamonds below the surface of the Earth, deeper than any drilling expedition has ventured, reports the Agence France-Presse wire. This discovery was made after “scientists were puzzled by observations that sound waves would speed up significantly when passing through the roots of ancient cratons.”
A new MIT study “offers ideas on job retraining programs for professional drivers and other workers who could be displaced by new technologies,” reports Callum Borchers for WBUR Bostonomix. The researchers hope to “provide a tool for people who might be planning these retraining programs that allows them to see what viable skill transformations exist," says graduate student Morgan Frank.
Using “recorded sound waves from seismic activity like earthquakes and tsunamis,” MIT researchers have found that there may be a quadrillion tons of diamonds under the Earth’s surface, reports Sarah Gray for Fortune. The seismic data provided this information, “because the speed of sound waves changes depending on the temperature, density and composition of the earth they travel through,” explains Gray.
In recent weeks, several groups of scientists have proven three of Einstein’s theories, reports Aristos Georgiou of Newsweek. Highlighting a team of researchers led by MIT Prof. Janet Conrad that proved Lorentz symmetry, Georgiou writes that their work “has shown that the great German physicist’s theory of special relativity applies even to tiny, high-energy subatomic particles known as neutrinos.”
