Phys.org / Newly identified 'saprotropism' helps roots avoid decaying plant matter—but not animal decay

Decaying matter shapes life in soil, but it can also create hostile zones for growing roots. Professor Jiří Friml of the Institute of Science and Technology Austria (ISTA) and international collaborators have now identified ...

Phys.org / Next‑generation membranes can refine crude oil using under half the energy of distillation

Oil refining is necessary for transforming raw, unusable crude oil into valuable goods like gasoline, diesel, jet fuel and petrochemical feedstocks. However, the usual distillation process is energy-intensive, spurring researchers ...

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 / AI reveals hidden San Andreas Fault movements

When people think about geological faults, they usually think about earthquakes. Yet faults do not move only during earthquakes. Sometimes they slip silently, without generating noticeable shaking, releasing stress over hours ...

Phys.org / Carbon–bismuth bonds reveal that relativity blurs the textbook line between sigma and pi bonds

Brown University chemists have provided direct evidence that upends the textbook explanation of how triple chemical bonds work in heavy elements. In a study published in Science, the researchers show evidence that when atomic ...

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. ...
