Rovers tend to be designed like little cars, equipped with wheels that spin on fixed axles. But that can leave the vehicles vulnerable to getting stuck, as Spirit infamously did on Mars. That's why School of Physics Daniel Goldman's team is finding new ways for rovers to move.

For every round-trip flight from NYC to London, 30 square feet of Arctic ice is lost. In 2017, Kim Cobb, of the School of Earth and Atmospheric Sciences, calculated that 85% of her carbon footprint came from flying. Shocked, she cut down her flying by three quarters. Cobb is part of a growing movement of people choosing to quit or hugely restrict their flying in hopes of reducing their carbon footprints due to travel. 

Dating back more than 3,000 years, knitting is an ancient form of manufacturing, but Elisabetta Matsumoto of the Georgia Institute of Technology in Atlanta believes that understanding how stitch types govern shape and stretchiness will be invaluable for designing new "tunable" materials. For instance, tissuelike flexible material could be manufactured to replace biological tissues, such as torn ligaments, with stretchiness and sizing personalized to fit each individual. Matsumoto is an assistant professor in the School of Physics. 

It’s not every day that a student takes the time to officially thank their professor for a great project. But that’s what Dr. Jennifer Glass’s student at Georgia Institute of Technology did after learning how to write Wikipedia articles as a class assignment. Glass is an assistant professor in the School of Earth and Atmospheric Sciences. This blog post discusses Glass's experience in assigning students to write for Wikipedia, instead of term papers.

The hurricanes that pounded Puerto Rico in 2017, blasting away most of its forest cover, may give scientists clues to how the world will respond to climate change and increasingly severe weather. Kim Cobb of the School of Earth and Atmospheric Sciences commented on the new experiments at El Yunque. “It is well worth the effort,” she said. “The raw beauty of these environments is really only matched by their immense scientific potential.” The work, with commentary from Cobb, was also reported by The New Zealand Herald.
