Phys.org / Chemistry-powered 'breathing' membrane opens and closes tiny pores on its own

Ion channels are narrow passageways that play a pivotal role in many biological processes. To model how ions move through these tight spaces, pores need to be fabricated at very small length scales. The narrowest regions ...

Phys.org / Mantle plume vs. plate tectonics: Basalt cores reshape the North Atlantic breakup debate

About 56 million years ago, Europe and North America began pulling apart to form what became the ever-expanding North Atlantic Ocean. Vast amounts of molten rock from Earth's mantle reached the ocean floor as the crust stretched ...

Phys.org / New study identifies sequence of critical thresholds for Antarctic ice basins

The Antarctic ice sheet does not behave as one single tipping element, but as a set of interacting basins with different critical thresholds. This is the finding of a new study by the Potsdam Institute for Climate Impact ...

Phys.org / Trapping a single protein in a molecular cage: A new path to drug discovery for amyotrophic lateral sclerosis

Proteins often function in pairs or groups, concealing their internal connection points and making it difficult for scientists to study their individual units without altering their natural structure. In a study published ...
