The Economist reports on an MIT study on the effectiveness of massive open online courses or MOOCs. Researchers found that MOOC participants “learned slightly more than they typically would in lectures.”

Professor Max Tegmark weighs in on the importance of Hugh Everett’s theory of the multiverse and his work developing the concept of mutually-assured destruction in a New Scientist article by Rowan Hooper. Everett “wrote arguably the first ever serious report on just how devastating a nuclear war would be for the US," says Tegmark.

Raghu Dhara of The Harvard Crimson writes that a new study by researchers from MIT, Harvard and Tsinghua University found that online courses are just as effective as traditional university courses. The study found that “the ‘learning gain’ of a group of MOOC students was comparable to that achieved by students enrolled in the same course at MIT,” explains Dhara. 

Issie Lapowsky writes for Wired about an MIT study that demonstrated that students who completed a physics class online learned as effectively as those who took it in person. “What’s more, the results were the same, regardless of how well the online students scored on a pre-test before taking the class,” Lapowsky writes.

Keith Wagstaff of NBC News reports on a new MIT study, which found that students who complete online courses end up with the same learning gains as those who attend class in person. “That goes for people of all education levels, from those with a high school diploma to those with a Ph.D.,” writes Wagstaff. 

Nick Anderson of The Washington Post writes about a new study showing that online courses can be an effective way to teach. “Students in a free online physics course from the Massachusetts Institute of Technology demonstrated roughly equal learning gains if they stuck with the class,” writes Anderson.

Kathryn Jepsen of Symmetry writes that new results from the AMS experiment, an international collaboration led by MIT Prof. Samuel Ting, indicate the detection of dark matter may be within reach. “It’s really profound to me, the fact that we’re getting this fundamental data,” said NASA Chief Scientist Ellen Stofan. “Once we understand it, it could change how we see the universe.”

In a piece published by The Huffington Post about a new time travel simulation, Lee Billings highlights Professor Seth Lloyd’s work developing a new model for a “closed timelike curve,” or a loop that could be traveled back into time.  

The Wall Street Journal interviews Professor Sara Seager about her research and her search for extraterrestrial life. "We haven't been able to find the true Earth twin yet because it's so very hard to find. It's like finding the proverbial needle in a haystack," says Seager. 

In a piece for Forbes, Nancy Pardo highlights the new Smart Morphable Surface developed by MIT researchers that can change its surface texture. The material could be used to make more aerodynamic and efficient vehicles.

Marcelo Gleiser writes for NPR about different theories on furthering our understanding of the universe, including Professor Max Tegmark’s book “Our Mathematical Universe.” “According to Tegmark, math is not just the tool we invent to describe both physical reality and pure rational constructions, but the very essence of nature,” writes Gleiser. 

Professor Marin Soljacic was one of three winners of the prestigious Blavatnik National Awards, reports Nature. Soljacic received the award for his work on electromagnetic phenomena, including wireless charging of batteries.

Jane Porter writes for Fortune about WiTricity, an MIT spinout focused on the development of wireless power-transfer technology. By using vibrational frequencies, electricity can be transferred over distances of up to four feet.

Wired reporter Nick Stockton reports on Prof. Pedro Reis’ work developing a morphable surface that could be used to increase the efficiency and speed of vehicles. The surface can, “wrinkle into a dimpled pattern similar to a golf ball’s, with similar aerodynamic properties.”

Ruth Graham of The Boston Globe writes about Professor Franz-Josef Ulm’s work with “urban physics.” Ulm’s research, “places him among a number of scientists now using the tools of physics to analyze the practically infinite amount of data that cities produce in the 21st century, from population density to the number of patents produced to energy bill charges.”
