Mashable reporter Emmet Smith spotlights how researchers from the MIT Media Matter Group have demonstrated how “silk can be harvested sustainably, using silkworms as active designers in the spinning of complex structures.”

Fast Company reporter Kristin Toussaint writes that a study by MIT researchers finds shutdowns and lockdowns caused by the coronavirus pandemic led to clearer skies and increased solar output in Delhi. “I think we’ve been able to get a glimpse of how the world can look like if we actually have clean air,” says research scientist Ian Marius Peters.

Architects from MIT and Generate Technologies have designed Boston’s first cross-laminated timber (CLT) building, a “’revolutionary’ type of timber [that] promises to reduce emissions that cause climate change, create affordable housing and jumpstart a new job-producing, homegrown industry in New England,” reports Bruce Gellerman and Kathleen McNerney for WBUR.

Gizmodo reporter Andrew Liszewski writes that CSAIL researchers have developed “a new spray-on ink that can infinitely change colors, designs, and patterns when blasted with different wavelengths of light.”

Verge reporter Justine Calma writes that states in the Midwest and Great Lakes region could see $4.7 billion in health benefits by maintaining current renewable energy standards. “This research shows that renewables pay for themselves through health benefits alone,” explains Emil Dimanchev, senior research associate at MIT’s Center for Energy and Environmental Policy Research.

A new study by MIT researchers examining the impact of energy policies that reduce fine particulates in the air finds that there are “substantial health benefits in Rust Belt states when utilities are required to supply escalating amounts of renewable power,” reports Ben Geman for Axios.

WCVB-TV’s Mike Wankum visits MIT to learn about the Solar Electric Vehicle Team. “We are trying to prove that we can move away from cars that rely on gasoline or diesel,” explains undergraduate Salem Ali, “and move towards more electric vehicles, and potentially even vehicles that you don’t have to plug in.”

John Yang reports for PBS NewsHour about technologies to harvest fog to secure the world’s water supply, including one system designed by Prof. Kripa Varanasi to collect water from power plant cooling towers. Varanasi and his team “discovered that zapping air rich in fog with a beam of electrically charged particles draws the droplets toward the mesh, dramatically increasing its ability to collect water,” says Yang.

A new MIT study shows that “China’s move away from fossil fuels would mean 2,000 fewer premature deaths in the U.S. by 2030,” reports John Fialka for E&E News. "It reminds us that air pollution doesn't stop at national boundaries," said Prof. Valerie Karplus, a co-leader of the paper. 

The BBC series “Follow the Food” spotlights how MIT researchers are tackling the issue of runoff pesticide pollution by developing a technology that helps pesticide better adhere to plant leaves. “What we are trying to do is come up with a technology that can help farmers and significantly reduce the amount [of pesticide] sprayed,” explains Prof. Kripa Varanasi.

Profs. Michael Strano and Sheila Kennedy have developed an exhibit for the Cooper Hewitt Design Triennial, which explores how Strano’s glowing plant research could be part of a sustainable energy future. “The pair is one of 62 design teams involved in the [Triennial], which highlights innovative ways humans are engaging with nature,” writes Emily Matchar for Smithsonian. 

Bloomberg News reporter Carol Massar spotlights how MIT researchers have developed a robot that can identify and sort recyclables. “The system includes a soft Teflon hand that uses tactile sensors to detect the size of an object and the pressure needed to grasp it,” Massar reports. “From there it can determine if it’s made of metal, paper or plastic.”

Scientific American reporter Jeremy Hsu highlights how CSAIL researchers have developed a robot that can automatically sort recycling. The robot “uses soft Teflon ‘fingers,’ which have fingertip sensors to detect object size and stiffness,” Hsu explains.

In an article for Fast Company about recycling, Adele Peters highlights MIT startup Renewlogy, which turns mixed plastic products into low-carbon, cost-competitive fuel. “To shift the needle and get recycling rates over 10%, you really need to focus on these low-value plastics,” says Renewlogy CEO Priyanka Bakaya, an MIT alumna.

In a letter to The Guardian, Prof. Franz-Josef Ulm, Randolph Kirchain and Jeremy Gregory of the Concrete Sustainability Hub argue that “concrete remains a vital means of social and economic transformation for developing nations.” The authors add that “we ought to expand our understanding of it and use its full potential to enable sustainable development.”
