FSNet is a new problem-solving tool that can find the optimal solution to an extremely complex problem without violating any of the problem’s many constraints. Developed at MIT, FSNet could help power grid operators manage electricity-production scheduling.

A new report proposes a range of initiatives to substantially reduce the harm caused by firearm violence in the United States over the next 15 years. The report, to be published Nov. 3 in the journal JAMA, proposes a range of initiatives. These include using artificial intelligence (AI) and other technologies to detect concealed weapons, and expanding programs that address poverty, social distrust and other factors behind violence in American communities. Since 2000, more than 800,000 Americans have been killed and more than 2 million injured by firearms. The report summarizes discussions of 60 experts in public health, criminology, sociology, social work, public policy and other fields. “We really tried to step back and think about what innovations are needed to address the firearm problem in a new way — realizing we live in a country with a Second Amendment and somewhere around 400 million firearms in private hands,” said Dr. Frederick P. Rivara, professor of pediatrics at the University of Washington School of Medicine. He chaired the summit.
