Phys.org / How phototherapy could reverse antibiotic resistance
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.
Phys.org / Nanoscale 'Bragg gratings' on photonic chips suppress noise in laser light
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. ...
Phys.org / Polymer beads generate electricity for self-charging devices using simple friction
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.
Phys.org / Songbird experts put superb fairy-wren danger call on the record
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.
Phys.org / CBD supplements may make dogs less aggressive over time
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.
Phys.org / Entanglement-enhanced optical lattice clock achieves unprecedented precision
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.
Phys.org / Physicist delineates limits on the precision of quantum thermal machines
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 ...
Phys.org / Astronomers capture an exceptional gamma-ray flare from a blazar
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 ...
Phys.org / Secret behind Temple of Venus's resilient construction uncovered
The material used to build the Temple of Venus in Naples has remarkably endured even as Earth's surface around it sank from volcanic activity, and researchers were curious to know how.
Phys.org / Major droughts linked to ancient Indus Valley Civilization's collapse
Successive major droughts, each lasting longer than 85 years, were likely a key factor in the eventual fall of the Indus Valley Civilization, according to a paper published in Communications Earth & Environment. The findings ...
Phys.org / Social media research tool can lower political temperature—it could also lead to more user control over algorithms
A new tool shows it is possible to turn down the partisan rancor in an X feed—without removing political posts and without the direct cooperation of the platform.
Phys.org / Thousands of genomes reveal the wild wolf genes in most dogs' DNA
Dogs were the first of any species that people domesticated, and they have been a constant part of human life for millennia. Domesticated species are the plants and animals that have evolved to live alongside humans, providing ...
