Lars Stevens-Cullinane works in a dark room. But he's not processing negatives and printing photographs on light-sensitive paper; he's testing whether brief flashes of light can make drug-resistant bacteria sensitive to antibiotics.

Researchers from The University of Osaka created a reagent for important building-block molecules with an abundant main-group element, gallium. These early findings show that an organic gallium compound can display transition-metal-like ...

Researchers at the University of Sydney have cracked a long-standing problem in microchip-scale lasers by carving tiny "speed bumps" into the devices' optical cavity in their quest to produce exceptionally "clean" light. ...

Yuwei Gu was hiking through Bear Mountain State Park in New York when inspiration struck. Plastic bottles littered the trail and more floated on a nearby lake. The jarring sight in such a pristine environment made the Rutgers ...

A University of Southampton study has revealed an intriguing new clue in the mystery of what triggers periods of very intense, brightly colored activity during displays of both the southern and northern lights.

Using catalytic chemistry, researchers at Institute of Science Tokyo have achieved dynamic control of artificial membranes, enabling life-like membrane behavior. The work is published in the Journal of the American Chemical ...

An international team has discovered a simple and environmentally friendly way to power the next generation of self-charging electronics. The work is published in Nano Energy.

After years studying wild birds in the bush, Flinders University experts have described a new call type frequently used by one of Australia's favorite birds, the superb fairy-wren.

In humans, CBD is thought to have therapeutic effects for some conditions including chronic pain, nausea, or inflammation. Now, dogs may be reaping some of the benefits, too, according to a new study.

Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.

Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing ...

Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, resulted in the detection ...
