By crushing raw elements under intense pressure, scientists created a new cobalt compound that organises its electron spins into a nanoscale checkerboard wave.

A review of 460 studies shows deep learning is replacing manual rules to track blood pressure, heart health, and sleep from simple light sensors.

By inserting two new genes into a common bacterium, researchers nearly doubled its ability to brew liquid biofuel from cheese-making waste.

A study of 31 stranded Yelkouan shearwaters along the Italian coast found plastic debris inside 90.3% of the birds, alongside widespread tissue contamination by synthetic plasticisers.

A systematic review shows how smart polymer networks tame water reactions and metal spikes to make zinc cells safer and longer-lasting.

A smart search code paired with fast machine learning shows where active metal atoms sit inside porous crystal grids.

A comprehensive review shows how special materials absorb destructive ultraviolet rays and re-emit them as visible light, shielding solar cells while boosting their power.

A lab protocol shows how to trap, isolate, and read protein-DNA interactions inside plant chloroplasts. By capturing the machinery that copies genes, scientists can track chloroplast activity with high precision.

A study of 41 species finds that shark skeleton mineralisation drops sharply with ocean depth, varying over 40-fold between surface dwellers and deep ocean species.

A 3D mapping study of 689 mouse brain cells reveals that subiculum cells branch out to share signals with several targets at once, rather than using separate, one-to-one lines.
