Phys.org / New catalyst could make mixed plastic waste recyclable in one chemical step

Ever wondered where your plastics end up? A PET bottle can be washed, shredded, melted and given a second life. But most everyday items—toys, mattresses, car seats—are made from different plastics that refuse to mix when ...

Phys.org / Krill buildup could slow fin whale filter-feeding unless baleen stays 15% clear

Usually there's safety in numbers, but it doesn't always work that way. Fin whales (Balaenoptera physalus) filter-feed on immense shoals of krill, engulfing colossal mouthfuls of water containing up to 144 kg of the crustaceans. ...

Phys.org / Wearables to track plant health: Farmers could use real-time information to manage crop conditions

A smartwatch can tell us the level of oxygen in our blood, when our sleep is restless or the number of steps we take in a day. Now imagine that kind of tracking ability for plants. By the time farmers see curling leaves or ...

Phys.org / Neutron imaging reveals how water limits CO₂ storage in recycled concrete

The construction sector faces two problems at once: it emits large amounts of CO₂ and produces vast quantities of concrete waste. But what if part of that waste could be used to trap carbon instead of ending up as rubble?
