New York Times reporters Emily Badger and Quoctrung Bui highlight Prof. David Autor’s new research that shows cities do not offer workers without college educations the same economic opportunities that they did in the past. Autor found that the declining urban wage premium has been caused by the “disappearance of ‘middle-skill jobs’ in production but also in clerical, administrative and sales work.”
Postdoctoral fellow Dheeraj Pasham speaks with Ira Flatow of Science Friday about his research calculating that a supermassive black hole 300 million light years from Earth is spinning at half the speed of light. Pasham explains that a black hole's spin rate provides information about the “channel through which it grew, all the way from a couple of years after the Big Bang until now.”
Space.com reporter Mike Wall writes that researchers have calculated a supermassive black hole’s rotation rate by analyzing the X-rays it emitted after consuming a nearby star. The researchers found that “the huge black hole, known as ASASSN-14li, is spinning at least 50 percent the speed of light.”
New York Times columnist David Leonhardt highlights Prof. Emeritus Olivier Blanchard’s address to the American Economic Association, in which he argued that governments are overly concerned with debt. “Blanchard’s case revolves around the fact that economic growth rates in modern times are usually higher than interest rates. This pattern means that governments can often repay their debts more easily than people expect,” Leonhardt explains.
Gizmodo reporter Ryan Mandelbaum writes that researchers determined how fast a supermassive black hole spins by measuring a star being swallowed by the black hole. Postdoctoral fellow Dheeraj Pasham explains that, “this measurement is different in the sense that we were able to measure the spin of a black hole that was dormant.”
Astronomers from MIT have detected echoes in X-ray flares emitted by a black hole consuming stellar material, writes Charles Q. Choi for Space.com. The findings “might shed light on how matter behaves not just as it falls into stellar-mass black holes,” writes Choi, “but also supermassive black holes millions to billions of times the mass of the sun.”
TechCrunch reporter Devin Coldewey writes that a team of researchers, including MIT scientists, have detected fast radio bursts (FRB) coming from a distant galaxy. Coldewey explains that the researchers used the Canadian Hydrogen Intensity Mapping Experiment radio telescope, which “points at the whole sky and chooses where to ‘look’ using software,” to identify 13 new FRBs.
MIT researchers have developed an inhalable form of messenger RNA that could be used to help treat patients with lung disease, reports Christopher Intagliata for Scientific American. Intagliata explains that researchers hope to one day “use this technique to help cystic fibrosis patients.”
Nature reporter Alexandra Witze highlights the TESS satellite’s success in uncovering new exoplanets outside our solar system. Senior research scientist George Ricker feels, “TESS works better than team members had dared to dream,” Witze writes, adding that “its four cameras can see objects 20% fainter, and focus more sharply, than originally expected.”
The Economist spotlights Prof. David Autor and graduate student Juliette Fournier’s research examining the economic prospects for Americans without college degrees. Autor and Fournier found that, “the earnings of workers without a college education have scarcely risen in 50 years, after adjusting for inflation; for men they have fallen. This stagnation coincided with tectonic changes in American employment.”
NASA’s MIT-led TESS mission has discovered a new exoplanet orbiting a star 53 light years from Earth, reports Mike Wall for Space.com. The “sub-Neptune” planet is “about three times bigger than Earth, which means it's likely gaseous rather than rocky,” writes Wall.
At the annual meeting of the American Economic Association, Prof. David Autor presented new research showing that middle-skill jobs for Americans without college degrees are becoming increasingly rare in dense areas, reports Jeanna Smialek and Peter Coy for Bloomberg News. “It’s not clear where the land of opportunity is for non-college adults,” says Autor.
CNN reporter Ashley Strickland writes that NASA’s planet-hunting satellite TESS has discovered another exoplanet 53 light years away. Strickland explains that the exoplanet orbits “a bright neighboring star in the Reticulum constellation, with a 36-day orbit and a surface temperature of 300 degrees Fahrenheit.”
NASA’s MIT-led TESS mission has discovered a new exoplanet that is about three times the size of Earth, reports Dennis Overbye for The New York Times. “There was quite some detective work involved, and the right people were there at the right time,” explains postdoctoral fellow Diana Dragomir. “But we were lucky, and we caught the signals, and they were really clear.”
Verge reporter Loren Grush writes that NASA’s MIT-led TESS mission has discovered a third exoplanet. “The important thing about this system that’s especially unique is it’s near to us,” says postdoc Diana Dragomir. “What that means simply is we can study this system in detail. We can measure the mass of the planet and measure things about the star.”
