Phys.org / Tunable laser light: Ring design could be used in telecom, medicine and more
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Technical University of Vienna (TU Wien) have invented a new type of tunable semiconductor laser that combines the best attributes ...
Phys.org / Real-time simulation makes understanding nonlinear quantum dynamics much easier
Many systems obey simple, linear rules: If you pull twice as hard on a spring, it stretches twice as far. However, when we introduce very large forces or complicated interactions, that linear rule breaks down into a "nonlinear" ...
Phys.org / BLOBS on the move: Deep Earth structures may explain giant volcanic explosions
Colossal volcanic eruptions like the kind that may have obliterated the dinosaurs more than 65 million years ago are caused by mantle plumes that rise from shifting underground mountains deep within the Earth's mantle, new ...
Dialog / Genetic 'barcode' discovery cracks the code of centromeres, the genome's most mysterious regions
When people think of DNA, they usually think of genes, the parts that code for proteins and drive inherited traits. But there's a whole lot of DNA beyond genes that we are just starting to understand. One such mysterious ...
Phys.org / Non-invasive video analysis tracks arthropod heart rates and reveals species differences
In a world-first pilot study, researchers from the University of South Australia have used video footage of insects to extract their heart rates without touching or disturbing them.
Phys.org / Genomic study reveals deep roots of human survival and adaptation in Himalayas
A new genomic study reveals how human populations adapted, survived, and diversified in the Himalayas, one of the most extreme and challenging environments on Earth.
Phys.org / Scientists develop novel recording tool to monitor protein kinase activities in living cells
The ability of protein kinases to transfer a phosphate group to target proteins plays an important role in many cellular processes. Scientists at the Max Planck Institute for Medical Research in Heidelberg have now developed ...
Phys.org / Algae unlock a cheaper, greener and more ethical way to grow cells
The time it takes to grow new skin for burns victims could be improved thanks to a new method of cell cultivation using algae, developed by University of Queensland researchers.
Phys.org / Measuring how—and where—Antarctic ice is cracking with new data tool
A total collapse of the roughly 80-mile-wide Thwaites Glacier, the widest in the world, would trigger changes that could lead to 11 feet of sea-level rise, according to scientists who study Antarctica. To better predict fractures ...
Phys.org / Summer floods of July 2021 exposed Meuse river's vulnerability
Four years ago, summer floods in Limburg—in the south of the Netherlands—drastically altered the riverbed of the Meuse, making accurate high-water forecasts even more difficult than usual. "This shows just how vulnerable ...
Phys.org / Sugar-coated 'sticky' stem cells could unlock surgery-free liver treatments
A new process could help to treat liver disease without needing an organ transplant, a new study reveals.
Phys.org / Turtles show remarkably low cancer rates, defying expectations for large, long-lived animals
A new study, led by experts at the University of Nottingham, provides the strongest evidence to date that cancer is extremely rare in turtles—a finding that could offer valuable clues for preventing or fighting cancer in ...
