In this video, Mashable highlights a new method developed by MIT researchers to 3-D print soft robots that can crawl, fold and carry a pill. The team hopes the structures, which can be controlled with a magnet, could eventually be used as a medical device to take tissue samples or deliver treatments.
A study from senior researcher Rolland Pellenq finds that grid-like cities retain more heat than those that are less-linear, due to the “Urban Heat Island” effect. “For new cities, or even neighborhoods, our findings can be used…in designing block layouts that would help optimize temperature,” Pellenq explains to Marlene Cimons of Popular Science.
Led by senior research scientist Rolland Pellenq, students in the School of Engineering developed a model “that links a city’s ‘texture’ to its night-time UHI (Urban Heat Index),” writes Laurie Winkless for Forbes. The team hopes their research will influence future urban development, especially in very hot or cold climates.
New research shows that using volcanic ash in cement mixtures could enable “stronger and more environmentally friendly” construction in future cities, reports Sydney Periera for Newsweek. “There may be a tremendous implication of energy savings at the city scale,” Prof. Oral Büyükoztürk tells Periera.
International Business Times reporter Himanshu Goenka writes about MIT’s recent research that examines how volcanic ash could serve as a concrete additive and reduce manufacturing energy usage by 16%. “Volcanic ash forms under high heat and high pressure, and nature kind of does all those chemical reactions for us,” said study coauthor Stephanie Chin, a senior in CEE.
MIT researchers have discovered a new family of viruses in the ocean that appears to play a key role in ocean ecosystems and could help provide insights on how viruses evolve, reports Marin Finucane for The Boston Globe. Finucane explains that the findings could also lead to, "a better understanding of human biology.”
A new study by MIT researchers found that the Clean Air Act has had a larger impact on reducing the mortality rate than originally thought, reports Alan Moses for U.S. News & World Report. The researchers found that, “the decline in organic aerosol may account for more lives saved than the EPA had estimated.”
A team of MIT students and postdocs has taken the top prize in the architecture category of the 2017 Mars City Design competition, reports Janussa Delzo for Newsweek. Delzo notes that the MIT team’s tree-inspired concept features “domes or tree habitats...large enough for 50 people to live inside of them."
In a letter to The Financial Times, Prof. Jessika Trancik, postdoc Geoffrey Supran, and graduate student Marco Miotti clarify results from a study the lab released last year that compares emissions of gas and electric vehicles. “Not only do electric cars usually emit less than petrol ones already, but over time, as the carbon footprint of electricity continues to fall, that gap will widen,” the researchers explain.
Boston Globe reporter Alyssa Meyers writes that a new study by MIT researchers shows that probiotics could be used to help fight high blood pressure. The researchers found that probiotics, “can boost beneficial bacteria in the human gut that prevent pro-inflammatory immune cells from increasing in number." Pro-inflammatory immune cells have been linked with hypertension.
Prof. Yossi Sheffi writes for The Wall Street Journal that students should be learning soft skills such as communications, leadership and teamwork, tools that are necessary for managing organizations and supply-chains successfully. Sheffi writes that, “professionals need to hone their ability to communicate with people working across a wide range of disciplines and a variety of geographies.”
A new study co-authored by research affiliate Judah Cohen shows that the extreme winters of the past few years can be attributed to the warming Arctic, writes Kendra Pierre-Louis for Popular Science. While most associate warmer temperatures with climate change, “a warming climate sends ripples of change across the entire climate system, which sometimes means some very cold winters.”
In an article for Popular Science, Kate Baggaley highlights Prof. Markus Buehler’s work developing materials that mimic a conch shell’s armor. “The actual material doesn’t matter—it’s the way the material is built together in forming these architectures,” explains Buehler.
The Economist highlights a study by MIT researchers that shows climate change could cause the flow of the Nile River to become more variable, increasing strain on regional water conflicts. The researchers found that while output could increase by up to 15%, variability would also increase, resulting in, “more (and worse) floods and droughts.”
AP reporter Katy Daigle writes that climate change could drive heat and humidity to extremes in regions of South Asia. Daigle explains that, “with no limit on global warming, about 30 percent of the region could see dangerous wet bulb temperatures above 31 degrees C (88 degrees F) on a regular basis within just a few decades.”
