According to Matt Kaplan of The Economist, Professor Ju Li has devised a method of producing lithium-ion batteries using nanoparticles. “If the process of making the nanoparticles can be industrialized," writes Kaplan, "then the lifetimes of lithium-ion batteries might be considerably extended.”
MIT researchers have developed a robot that can 3-D print the basic structure of buildings, writes Matthew Hutson for Science. The autonomous robot sprays an expanding foam into the desired shape “to build up a hollow wall that serves as insulation and can later be filled with concrete and covered in plaster,” explains Hutson.
In an article for The Atlantic, Gillian B. White writes about Prof. Peter Temin’s new book, “The Vanishing Middle Class: Prejudice and Power in a Dual Economy.” White writes that in his book Temin argues that “following decades of growing inequality, America is now left with what is more or less a two-class system.”
Boston Globe reporter Steve Annear writes about the Baker House Piano Drop, an MIT tradition started more than 40 years ago, during which students drop a non-working piano from the roof of Baker House. This year’s event will raise funds for The Stepping Stone Foundation, which implements programs that prepare underserved schoolchildren for educational opportunities.
CBC News reporter Matthew Braga writes that MIT researchers have designed a system that can 3-D print the basic structure of buildings. The researchers believe the system could one day be used to “build structures in extreme or inhospitable environments — say, the aftermath of an earthquake, or even on another planet.”
