The week in physics: Chiral-induced spin selectivity; Land subsidence affects cities on river deltas

The Week in Physics Cities built on river sediment are sinking Using high-resolution satellite data for a global analysis of major river deltas, researchers found that 45% of those studied are sinking faster than the rate of sea-level rise. Laura Fattaruso MAR 11, 2026 How the twist of a molecule affects electron spin Since the discovery was first reported in 1999, researchers have uncovered many aspects of the chiral-induced spin selectivity effect, but its underlying mechanisms remain unclear.
