A review of materials chemistry explores how chitosan hydrogels can stick inside infected gum pockets to release medicines and encourage tissue repair on demand.
Marine clouds do not react to pollution straight away; their cover peaks a day later and hundreds of kilometres downwind. This delay reshapes how scientists calculate cloud cooling effects.
Combining lab DNA tools with Indigenous Ecological Knowledge builds fairer, stronger wildlife protection, but real success requires treating local groups as equal partners.
Marine experts argue that our main global safety framework largely overlooks deep-sea damage and widespread ocean oxygen loss. Filling these gaps is tricky because complex marine tipping points rarely boil down to single global numbers.
Microbes at seafloor cold seeps consume substantial amounts of methane, locking their digestion speed into rock chemistry over the past 100,000 years.
By tracking an experimental cotton cross with three genetic screening methods, scientists flagged five candidate genes tied to surviving severe dry spells.
Tracking gaze during virtual journeys shows that eye movements reveal hidden mental doubts and predict changes of mind before subjects alter course.
Lab tests show gas bubbles stuck tightly to liquid metal drops in molten young worlds, dragging atmospheric elements down deep inside them.
A new framework embeds invisible digital stamps that survive harmless image tweaks but tear apart when malicious deepfakes occur. In tests on facial datasets, it beat existing methods by over 4.5%.
A modelling study of the Great Barrier Reef shows that tracking reef health, rather than just location, completely changes which areas need urgent protection.
