Cellular changes to adipose tissue after weight-loss surgery could point to pathways responsible for the metabolic benefits of this procedure.

Building a quantum computer out of silicon allows the computer’s qubits to be integrated seamlessly with their control electronics, but the control circuits can degrade qubit performance. A cryogenic control chip counters this risk and holds promise for scaling up the number of qubits.

Airborne particles adhere to filters only weakly. A filtration strategy that mimics the effects of the mucus layer coating nasal hairs captures particulate matter effectively, owing to a mechanism called capillary adhesion. Filters using this technology perform better than conventional air filters and have a longer lifespan.

A landmark field study reveals widespread pollution of the Atlantic Ocean by nanoscale plastic debris — raising questions about the risk to marine ecosystems.
