Phys.org / Cells have a secret power line: How the nucleus gets its own private energy supply from mitochondria

For decades, biologists assumed a cell's energy simply diffused to wherever it was needed. It turns out the most important destination of all has a private delivery line.

Phys.org / Hurricane rainfall and landslide risk are on the rise in Southern California

Climate change could make historically rare tropical storms in Southern California produce significantly more precipitation in the next few decades, and when they strike, landslides are likely to become a bigger risk across ...

Phys.org / Novel catalyst design boosts solar-driven ammonia production under mild conditions

Sunlight, water, air and metal-organic catalysts—that could be all it takes. TU Wien has shown how catalyst design can be advanced for solar-driven NH3 synthesis. Without this chemical technology, feeding the world as we ...

Phys.org / 80-atom boron 'buckyball' finally steps into nanotechnology's spotlight

The nanoscale world appears to have a new ball to kick around. Researchers from Brown University have shown the first experimental evidence for a "buckyball" molecule made from 80 boron atoms. The new structure is the cousin ...

Phys.org / 'Cold insurance' for crops: Researchers unlock 'on-demand' climate resilience

Rapidly intensifying global climate instability is causing increasingly erratic temperature fluctuations. When sudden cold snaps strike during a crop's critical flowering window, they trigger irreversible pollen abortion, ...

Phys.org / Algorithm visualizes how cells 'talk' to one another across tissue and time

People communicate with each other, sometimes face to face, sometimes with a text message or phone call. Cells also communicate with each other, sometimes by touching and sometimes by sending signals across space and time. ...
