Matt Cantor of USA Today writes that by examining the key features that augment a violin’s sound, MIT researchers have found that the shape and design of the “f-holes” give the instrument its acousitcal power. The researchers also found that the instrument’s shape evolved gradually over time, by chance.
MIT researchers have found that few health care studies use the random assignment method, considered to be the gold standard in scientific research, reports U.S. News & World Report. The researchers “analyzed hundreds of studies about improving health care and found that only 18 percent of those conducted in the United States used the random assignment method.”
The Economist writes about a new MIT study examining the development of violin design, which was found to have evolved by chance. The researchers also found that the shape and length of the violin’s “f-holes” give the instrument its acoustical power.
A new study conducted by researchers from MIT found that a violin’s acoustic power comes from the design of the instrument, writes Joseph Dussault of The Christian Science Monitor. The researchers also found that the “violin’s distinctive, f-shaped sound hole came not as a result of human ingenuity, but rather a series of random mutations.”
A new study by Prof. Amy Finkelstein found that few health care system studies used the random assignment method, considered the gold standard for scientific research, reports Sabrina Tavernise for The New York Times. “The beauty of randomization is that it allows you to be sure of the cause,” says Finkelstein of the importance of using the method.
Devin Coldewey of NBC News writes about new MIT research into the evolution of violin design. The researchers found that “the characteristics of the instruments underwent changes surprisingly like evolution by natural selection,” Coldewey explains.
The Huffington Post reports on an analysis of the Mars One project led by Professor Olivier de Weck. “We’re not saying, black and white, Mars One is infeasible,” explains de Weck. “But we do think it’s not really feasible under the assumptions they’ve made.”
Michelle Roberts reports for BBC News on a new, “smart insulin” being developed by MIT researchers that switches on when blood sugar rises. The engineered insulin could make it easier for those suffering from diabetes to manage the disease, Roberts explains.
A paper co-authored by Professor Daron Acemoglu has raised questions about a new theory that inequality increases when the return on capital exceeds the rate of growth, reports Angela Chen for The Wall Street Journal. Acemoglu contends that the new model fails to account for political institutions and technology.
Slate reporter Alison Griswold writes about a new MIT study examining what makes certain startups successful. “We’re trying to measure things that companies do naturally when they have the ambition and potential to grow,” says Prof. Scott Stern.
USA Today reporter Melissa Pandika spotlights Prof. Kay Tye, highlighting her journey to MIT, her award-winning breakdancing skills and her neuroscience research. Tye’s current work examines how optogenetics can be used to control certain behaviors, such as overeating and anxiety.
Prof. Richard Nielsen writes for The Washington Post about his view that the Islamic State does not believe in state sovereignty, and the difficulties this view poses for working with the group. Nielsen writes that the group’s existence, “poses a fundamental challenge to international order, not only to the people under its rule.”
Francie Diep writes for Popular Science about how a new mathematical theory developed by MIT researchers may help to explain how surfaces wrinkle. “The equation could help chemists working on high-tech materials,” explains Diep.
MIT researchers have developed a method to identify entrepreneurial “hotspots,” reports Lisa Krieger for San Jose Mercury News. Researchers found that areas like Silicon Valley can help companies “realize their promise on a more guaranteed basis," explains Prof. Scott Stern.
Kevin Hartnett of The Boston Globe looks at Professor Christine Ortiz’s work to develop better body armor technology by mimicking the tough qualities of fish scales. “Armored fish have multi-hit capability,” explains Ortiz. “Basically, when it gets hit, it just cracks locally in a circle.”
