Sound's Quantum Jumps Captured in Real Time for First Time
The first direct observation of sound's quantum jumps could sharpen quantum error correction and enable new biological sensors.
Humpback whale mother lingers with dead calf off Australia's Gold Coast
A rare observation suggests humpback whales may display mourning-like behavior after losing a calf.
Concrete Blend Gains Strength and Absorbs CO2
Researchers report a zeolite-bamboo biochar concrete that outperforms conventional mix while pulling carbon dioxide from the air.
Amateur Astronomer Spots 390-Million-Year-Old Impact Crater on Satellite Map
A chance discovery on satellite imagery has been confirmed as a massive ancient impact crater in Quebec.
Oklahoma meteor crater is 100 million years younger than thought
Zircon dating places the Ames impact in the Late Devonian, linking it to a major marine mass extinction rather than the Ordovician Meteor Event.
Light-activated MOF produces hydrogen without costly metal catalyst
A new sulfur-based photocatalyst splits water into hydrogen using only light, potentially lowering the cost of green fuel.
Forgotten 30-year forest experiment reveals benefits of heavy thinning
A long-neglected Australian experiment found heavily thinned mountain ash forests grew larger trees and stored as much carbon as unharvested areas.
Computational framework maps temporary cues to redirect cell fate
Korean researchers built a general-purpose tool that finds gene targets for steering cell identity with a transient stimulus, avoiding permanent genetic changes.
Sheep grazing may threaten Scotland's wild pollinators more than honey bees
A new study suggests that spring sheep grazing on Scottish moorlands could be a greater driver of wild pollinator decline than competition with honey bees.
Why Lightning Delays Save Lives Even Under Clear Skies
A sports meteorologist explains that game delays for lightning are a critical safety measure, despite fan frustration on sunny days.
Camphor receptor may trigger female mosquito's switch to blood
A new study identifies an odor receptor for camphor that could explain how young female mosquitoes transition from nectar feeding to seeking blood.
