A new study co-authored by researchers at MIT finds that, “human activities are altering Earth's seasons in a way that is creating a greater contrast between summer and winter in much of North America, Europe and Eurasia,” reports Andrew Freedman for Axios.
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.”
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.
MIT research scientist Ulrich Faul used seismic data to determine that there may be diamonds underneath the Earth’s surface. “Located over 100 miles below Earth's tectonic plates are ancient, hard rocks called ‘cratonic roots’ that potentially consist of one to two percent diamond — totaling a quadrillion tons,” writes Lilly Price for USA Today.
A study led by MIT research scientist Ulrich Faul finds that diamonds are about 1,000 times more common in the Earth than previously thought, report Ayana Archie and Ralph Ellis for CNN. “The deposits sit some 90 to 150 miles below the Earth's surface, much deeper than current mining machinery allows,” write Archie and Ellis.
A team led by MIT research scientist Ulrich Faul ‘discovered a gigantic cache of diamonds deep beneath the Earth’s surface,’ writes Avery Thompson for Popular Mechanics. While the diamonds are too deep to be mined, “knowing that they’re there helps us learn more about our own planet and what it’s made of,” Thompson notes.
By using sound waves, MIT researchers have discovered that part of Earth’s stable crust may contain diamonds, reports Abbey Interrante for Newsweek. “This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it’s relatively common,” says research scientist Ulrich Faul.
NBC Mach’s Denise Chow discusses the upcoming hurricane season with Prof. Kerry Emanuel. “The sea level is going up, and it's almost certainly going to continue to go up,” explains Emanuel. “Even if the storms themselves don’t change, the surges are riding on an elevated sea level, and that makes them more dangerous.”
NASA’s planet-hunting satellite TESS has “snapped its first test shot — an incredibly clear, star-studded image centered on the Southern constellation of Centaurus,” writes Bruce Dorminey for Forbes. “We are truly excited about how well the TESS cameras are working,” said George Ricker, the mission’s principal investigator and a senior research scientist at MIT’s Kavli Institute.
In an article for Salon, Associate Prof. Noelle Eckley Selin and postdoc Sae Yun Kwon discuss their latest research, which examined emissions in China. They write that although mercury pollution is often associated with fish consumption, “China’s future emissions trajectory can have a measurable influence on the country’s rice methylmercury” levels, as well.
NASA’s recently launched Transiting Exoplanet Survey Satellite (TESS) “will spend the next two years scanning 200,000 stars looking for any exoplanets orbiting them,” explains New Scientist. In about two months, once the satellite is in orbit and its cameras are tested, “there’ll just be a flood of information,” says MIT’s George Ricker, the principal investigator on TESS.
Using several comparative models, a new study led by MIT researchers reveals that China’s pledge to peak its carbon emissions by 2030 could cut down on as many as 160,000 premature deaths. “Politically, the research confirms why Chinese officials have their own internal reasons to cut CO2 even though the U.S. is abandoning Paris and disengaging internationally on climate,” writes Ben Geman for Axios.
A new study finds that a 4% reduction in China's carbon emissions by 2030 could save a total of $464.5 billion in healthcare costs, writes Chase Purdy for Quartz. “We have all these policy goals for a transition toward a more sustainable society,” says Associate Prof. Noelle Selin. “Mitigating air pollution, a leading cause of death, is one of them, and avoiding dangerous climate change is another.”
NASA has successfully launched its “planet-hunting” Transiting Exoplanet Survey Satellite, more than a decade after MIT scientists first proposed the idea of a mission like TESS, reports Ashley Stickland for CNN. “NASA believes that TESS will build on Kepler’s momentum and open the study of exoplanets in unprecedented ways,” writes Strickland.
