A study by MIT researchers examining the carbon emissions of self-driving cars found that “the power required to run one billion driverless vehicles driving for one hour per day could consume as much energy as all existing data centers in the world,” reports Claire Brown for The New York Times. Graduate student Soumya Sudhakar explains that another big unknown is how autonomous vehicles could change the way people travel, adding to the uncertainty over the overall long-term emissions outlook for self-driving cars. 

Prof. Sara Beery spoke at TED Radio Hour about her work developing Inquire, an AI tool aimed at supercharging ecosystem conservation that is trained on millions of photos captured by citizen scientists, reports GBH. “Under the hood, what we’re doing is we’re developing AI models that can learn and understand similarities between images and scientific language,” explains Beery. 

CNN spotlights how MIT researchers have developed a new ultrasonic device that can extract clean drinking water from moisture in the atmosphere. “This method is much faster, we’re talking minutes instead of hours, compared to the old way,“ CNN explains. The new device “could be a game-changer in desert conditions, and for communities around the world that don’t have reliable access to drinking water.” 

Researchers at MIT have developed a new “system that uses a vibrating ceramic ring to produce clean drinking water from humid air in several minutes,” reports Matthew Burgos for DesignBoom. Burgos explains that with the system developed by MIT researchers, "clean water-making can take a few minutes versus the tens of minutes or hours required by thermal designs. In their system, the engineers use ultrasonic waves to shake the water out of the material that can absorb moisture from the air.” 

Noman Bashir, a fellow with MIT’s Climate and Sustainability Consortium, speaks with Smithsonian Magazine reporter Amber X. Chen about the impact of AI data centers on the country’s electric grid and infrastructure. Bashir notes “that the industry’s environmental impacts can also be seen farther up the supply chain,” writes Chen. “The GPUs that power A.I. data centers are made with rare earth elements, the extraction of which Bashir notes is resource intensive and can cause environmental degradation.” 

Prof. Caitlin Mueller has been named Innovator of the Year by Architectural Record for her work advancing a “vision for building design and construction that unites these disciplines with computation to create structure that are sustainable, high performing, and delightful,” reports Architectural Record. “Her group develops computational design and digital fabrication methods that integrate efficiency, performance, material circularity, and architectural expression,” Architectural Record notes. “This work spans robotic assembly of optimized trusses, fabrication of low-cost earthen and concrete systems, and algorithmic strategies for reusing salvaged wood and reassembled concrete parts.” 

Researchers at MIT have found that up to 98% of the energy produced by an earthquake dissipates as heat, reports Stephanie Pappas for Scientific American, who notes that the findings could be used to help create better earthquake forecasts. The researchers “created itty-bitty lab earthquakes by pressing centimeter-sized wafers of a powdered granite and magnetic particle mixture between aluminum pistons until the wafers slipped or snapped,” explains Pappas. “They measured this process of cracking under stress with thermometers and piezoelectric sensors that mimic the seismographs used to measure real earthquakes.” 

Prof. Xuanhe Zhao and his research group have been named one of the winners of the 2025 Gizmodo Science Fair for their work “creating an atmospheric water harvesting device that could improve access to potable water in the most remote, arid regions of the world,” reports Ellyn Lapointe for Gizmodo. “We are truly proud and excited about this work—and about the potential to help people most in need of safe drinking water,” Zhao said.

Researchers at MIT have created “a series of miniature, controlled versions of real earthquakes to see where all that destructive energy actually goes and what it’s doing,” reports Luis Prada for Vice. “The goal of the research is to isolate the key physical processes that underlie every earthquake,” explains Prada. “The hope is that any knowledge gained will help refine earthquake prediction models and possibly even pinpoint which regions are sitting on fault lines ready to pop.” 

Gizmodo reporter Gayoung Lee writes that MIT researchers created “lab quakes” or miniature versions of earthquakes in a controlled setting and found that “anywhere between 68 and 98% of the energy goes into generating heat around a quake’s epicenter.” The findings “could help inform the creation of a physical model for earthquake dynamics or seismologists’ efforts to pick out regions most vulnerable to earthquakes.”

Boston Globe reporter Jon Chesto spotlights the kickoff event for the new MIT-GE Vernova Energy and Climate Alliance, which will “fund research initiatives, fellowships, and other programs with an eye toward improving energy technologies and decarbonization.” GE Vernova CEO Scott Strazik emphasized that he has been impressed with the passion and talent for clean-tech among the students at MIT and other universities. “I started these discussions with the objective that we should inspire future leaders to come into our industry and ideally come to our company,” Strazik said. “They’ve probably inspired us more than we’ve inspired them.”

Writing for Nature, Prof. Danielle Wood makes the case that both public and commercial satellite missions are needed to understand and protect the environment. “Although commercial companies have much to offer, the public sector must still lead the design, operation and management of satellites, and remain committed to tracking changes on Earth comprehensively, openly and transparently,” Wood writes. 

Writing for the Financial Times, Prof. Carlo Ratti makes the case that “in a hotter world, trees should be considered more than decoration. This ancient infrastructure can cool not just our buildings but the cities themselves. And with AI, we can now plant better, with precision urban forestry. In a warming world, the smartest climate tech may be rooted in the ground — and it doesn’t strain the power grid.”

Prof. Christopher Knittel speaks with WBUR reporter Miriam Wasser about the decision to build a new natural gas pipeline in New England. "A new pipeline would allow more natural gas to reach us in periods when we really need it," says Knittel. "So that's where the big savings would be."

Researchers at MIT have found that “tropical forests populated with a diversity of seed-dispersing animals can accumulate carbon up to four times as fast as fragmented forests where these animals are absent or their movement is restricted,” reports James Dinneen for New Scientist. “This shows a linkage between animal biodiversity loss and a process that exacerbates climate change,” says research scientist Evan Fricke. “We’re losing the regrowth potential of tropical forests.”
