Will iceberg twice the size of NYC break off Antarctica this year?
A crack on the Antarctic ice shelf grew dramatically in late 2020 into 2021. Scientists are watching to see if the rapidly accelerating crack will cause the shelf to rip apart before Antarctica’s sunlit summer season – going on now – comes to an end.

From Rocks To Icebergs, the Natural World Tends To Break Into Cubes
sciencehabit shares a report from Science Magazine: Researchers have found that when everything from icebergs to rocks breaks apart, their pieces tend to resemble cubes. The finding suggests a universal rule of fragmentation at scales ranging from the microscopic to the planetary. The scientists started their study “fragmenting” an abstract cube in a computer simulation by slicing it with 50 two-dimensional…
