David Weinberg of Marketplace reports that MIT researchers have developed a formula for concrete that reduces its greenhouse-gas emissions. Dr. Roland Pellenq explains that to make a “greener” cement, researchers examined concrete’s properties at the “sub-micron or big-nano level.”
Founded by MIT alumnus Sidhant Pai and winner of the MIT IDEAS Global Challenge, Indian startup Protoprint compensates waste pickers in the Indian city of Pune for collecting the raw materials used for 3D-printing filament, writes Dhanya Ann Thoppil for The Wall Street Journal. “The point is to create employment and value add opportunities for the waste pickers,” says Pai.
Professor Chris Knittel writes for WBUR that the People’s Climate March held in New York City may have played to the wrong audience. “Real change will only come about when politicians and others see real consequences for their positions, or lack thereof, on climate change,” Knittel writes.
Professor Rolland Pellenq’s team has developed a new formula that would reduce the greenhouse gas emissions associated with concrete production by half, reports Julia Pyper for Scientific American. The mixture also achieves "two times the resistance of normal cement, in mechanical resistance to fracture,” says Pellenq.
“We are swinging to fossil fuels in ways that couldn't have been imagined a few years ago,” says Professor Michael Greenstone in this New York Times piece by Eduardo Porter. Greenstone argues that fossil fuel innovation has undermined efforts to expand carbon-free energy sources.
Prof. John Lienhard, head of MIT’s Abdul Latif Jameel World Water and Food Security Lab (J-WAFS), discusses the new lab with Najlaa Habriri of Asharq Al-Awsat. Habriri calls J-WAFS an "ambitious project to tackle worldwide food and water insecurity."
Tom Ashbrook speaks with Senior Lecturer Frank Ackerman during this audio segment on NPR’s On Point. Ackerman talks about the importance of putting in place policies that put a price on carbon emissions.
Bloomberg Businessweek reporter Peter Coy writes about how researchers from MIT and other universities simulated 549 storm surges in New York City and analyzed the effectiveness of different defenses. The researchers found that the most cost-effective method is to allow storm waters to flood the city while protecting critical infrastructure.
Austin Hess reports on MIT’s new environment initiative in an article for The Tech. “MIT undertakes initiatives to inspire genuinely new ideas and the initiative on the environment will be no exception,” Maria T. Zuber, MIT Vice President for Research, told The Tech.
GreenWire reporter Katherine Ling writes about MIT’s new environment initiative. The initiative will, "use interdisciplinary research across physical and social sciences, engineering, and urban planning and policy to address environmental problems.”
“The function of xylem's filtration formed the basis of a paper published this week by a team from the Massachusetts Institute of Technology,” Jason Tetro writes of Rohit Karnik’s work with water filtration in the Huffington Post. “The premise was that xylem could help to filter water and make it safe to drink.”
The Financial Times explores new MIT research into the mechanics behind underwater or “internal waves.” Through their work, which could prove useful in climate modeling, researchers found that ocean ridges and channels cause the gigantic waves to form.
