New ‘smart’ fibers curb fires in lithium-ion batteries. Science News

Hoverboards and certain cell phones powered by lithium-ion batteries occasionally go up in flames. Scientists now have a new plan for squelching these fires before they flare out of control: incorporating a flame retardant in the battery that’s released if temperatures get too toasty.  Read more…

Massive ice shelf is poised to break off of Antarctica. Science News for Students

One of Antarctica’s largest ice shelves is nearing its breaking point, scientists warn. A colossal crack in this ice shelf, known as Larsen C, abruptly grew by 18 kilometers (11 miles) during the second half of December 2016. (That was the height of the region’s summer.) Members of Project MIDAS, an Antarctic research group, reported the crack’s dramatic growth on January 5. This separating ice is now only about 20 kilometers from Larsen C’s edge.  Read more…
