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 / Rare stone tool cache found in Australian outback tells story of trade and ingenuity
About 170 years ago, a large bundle of stone tools was deliberately buried close to a waterhole in the remote Australian outback. Who buried them and for what purpose? Why were they never retrieved?
Phys.org / Quasi-periodic oscillations detected in unusual multi-trigger gamma-ray burst
A new study led by the Yunnan Observatories of the Chinese Academy of Sciences has detected quasi-periodic oscillation (QPO) signals in an unusual gamma-ray burst (GRB) event. The findings are published in The Astrophysical ...
Phys.org / Advanced tracking uncovers flapper skate hotspots on Scotland's deep seabed
Flapper skate (Dipturus intermedius), the world's largest skate species measuring over two meters in length, live hidden on the rugged seabed around Scotland. Their life in the darkness, deep underwater, makes it extremely ...
Phys.org / 'Stick and glue' method enables more precise biomolecule tracking in cells
A team of researchers at IOCB Prague headed by Dr. Tomáš Slanina has developed a new method for labeling molecules with fluorescent dyes that surpasses existing approaches in both precision and stability. The new fluorescent ...
Phys.org / Latent antimicrobial resistance is widespread across the world, research discovers
A group of researchers has analyzed 1,240 wastewater samples from 351 cities in 111 different countries and found that bacterial latent antimicrobial resistance is widespread on all the world's continents. The research was ...
Phys.org / An unusually 'sticky' RNA class that keep cells organized: Researchers discover smOOPs
Inside cells, RNAs and proteins form tiny, liquid-like droplets called biomolecular condensates. These droplets are essential for organizing cellular life, yet why some RNAs cluster more readily than others has remained unclear. ...
Phys.org / Lake heat waves are more intense, longer-lasting than atmospheric ones, new study reveals
Freshwater lakes are critical ecosystems that regulate regional climates, support biodiversity, and provide essential resources for human societies. However, as global warming accelerates, extreme heat waves are increasingly ...
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 / Artificial membranes mimic life-like dynamics through catalytic chemical reactions
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 ...
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.
