More than 200 colleges and universities have backed a legal challenge by MIT and Harvard to a new visa policy that would bar thousands of foreign students from studying in the U.S., reports Collin Binkley for the Associated Press. “These students are core members of our institutions,” the schools wrote. “They make valuable contributions to our classrooms, campuses and communities.”
Using a scanning electron microscope, MIT researchers observed how hair produces tiny chips in steel razor blades, reports Nell Greenfieldboyce for NPR. "For me, personally, it was both a scientific curiosity, of 'What's going on?' and also aiming to solve an important engineering problem," says Prof. C. Cem Tasan.
By observing and recording the cutting process, MIT researchers have found that human hairs chip razor blades during the shaving process, reports Leah Crane for New Scientist. “We expected that the failure of these materials should just be wear,” says Prof. C. Cem Tasan. “But this is not the case: the process of chipping is much faster.”
Wired reporter Eric Niiler writes that a new study by MIT researchers sheds light on why razor blades get dull so quickly. “We want to design new materials that are better and go longer,” says Prof. C. Cem Tasan. “This problem of the blade is an excellent example. We are so used to it, you don’t think about it. You use the razor for a few weeks and then move on.”
Diane Greene SM ’78, a life member of the MIT Corporation, speaks with Becky Quick of CNBC about the future of AI. Greene explains that companies can now combine data with computational power, so that an “algorithm can learn from the data. Once you start doing that you start getting insights you’ve never gotten before that can leapfrog what you’re able to do.”
