Army-funded researchers have finally cracked how to make materials capable of self-propulsion, meaning materials can now move without the need for motors. The scientists responsible suggest this breakthrough could forge the next generation of self-powered military tech.

When different groups of people come into contact, what s the key to motivating advantaged racial groups to join historically disadvantaged racial minority groups to strive for racial equality and social justice? It s a complex conundrum studied for years by social scientists like Linda Tropp, professor of social psychology at the University of Massachusetts Amherst.
Her latest research, published in the
International Journal of Intercultural Relations, tested and supported Tropp and colleagues proposition that having open communication about group differences is a crucial pathway.

Imagine a rubber band that was capable of snapping itself many times over, or a small robot that could jump up a set of stairs propelled by nothing more than its own energy. Researchers at the University of Massachusetts Amherst have discovered how to make materials that snap and reset themselves, only relying upon energy flow from their environment. The discovery may prove useful for various industries that want to source movement sustainably, from toys to robotics, and is expected to further inform our understanding of how the natural world fuels some types of movement.
Al Crosby, a professor of polymer science and engineering in the College of Natural Sciences at UMass Amherst, and Yongjin Kim, a graduate student in Crosby s group, along with visiting student researcher Jay Van den Berg from Delft University of Technology in the Netherlands, uncovered the physics during a mundane experiment that involved watching a gel strip dry. The researchers observed t
Study examines impact of high volume testing at colleges on county COVID data

NORTHAMPTON A particular graph caught Susan Voss’ eye when she looked at the state’s weekly COVID-19 data report for data to inform her family and her position as a School Committee member.
“All fall I really was concerned about this graph,” the Northampton resident said. “It showed the differences in the percent positivity if you remove higher education versus keeping higher education. It’s a really big difference.”
