Water Molecules at Salt Water’s Surface Organized Differently than Previously Thought: Study

Litman et al. show that ions and water molecules at the surface of most salt-water solutions, known as electrolyte solutions, are organized in a completely different way than traditionally understood. Image credit: Litman et al., doi: 10.1038/s41557-023-01416-6.

The distribution of ions at the air/water interface plays a decisive role in many natural processes. Several studies have reported that larger ions tend to be surface-active, implying ions are located on top of the water surface, thereby inducing electric fields that determine the interfacial water structure. However, new research by chemists from the University of Cambridge and the Max Planck Institute for Polymer Research challenges this view. Their...

The colored plots illustrate neural activity recorded in mouse visual cortex (V1); each row of tick marks represents the spikes of a different neuron; researchers can predict the target side from the neural activity with near perfect accuracy, animal subjects get many masked trials wrong due to how brain regions downstream of V1 process this information.

Map of Sahul showing the extent of the now-submerged continental shelf (dark gray), with the area of the Northwest Shelf demarcated by a dashed black box, and the present-day distribution of the Köppen climate groups (seasonal precipitation and temperature) showing the extent of modern-day Australia and New Guinea. The tropical distribution of Late Pleistocene sites containing early axe technology are shown as black circles, sites without early axe technology as gray circles, and sites demonstrating Late Pleistocene occupation of the now submerged continental shelves as white circles.
