Breaching the horizons: Universal spreading laws confirmed – By extending the computational horizons from one day to the unprecedented time scales, the IBS researchers were able to confirm that a cloud of quantum particles continue to spread even when particle to particle interactions originally deemed to be the activator of the spreading, exert almost no strength. Their findings are published online in Jan. 30, 2019, in Physical Review Letters.

West Antarctic ice collapse may be prevented by snowing ocean water onto it – The ice sheet covering West Antarctica is at risk of sliding off into the ocean. While further ice-sheet destabilisation in other parts of the continent may be limited by a reduction of greenhouse gas emissions, the slow, yet inexorable loss of West Antarctic ice is likely to continue even after climate warming is stabilised. A collapse might take hundreds of years but will raise sea levels worldwide by more than three meters.
