    New Englanders are accustomed to cold weather, snow and ice, but Friday night's combination of extreme cold and powerful winds is enough to make even bundled-up skiers shelter indoors. Winter misery is making its way into New England with a potentially deadly mix. Forecasters are predicting “once-in-a-generation” wind chills, as low as minus 50 Fahrenheit.

U.S. restrictions against China's computer chips industry are meanwhile slowing progress in developing advanced chips and other leading technologies.
