Phys.org / Atomic-level surface control boosts brightness of eco-friendly nanosemiconductors by 18-fold
Light-emitting semiconductors are used throughout everyday life in TVs, smartphones, and lighting. However, many technical barriers remain in developing environmentally friendly semiconductor materials.
Phys.org / A 'cosmic clock' in tiny crystals reveals the rise and fall of Australia's ancient landscapes
Australia's iconic red landscapes have been home to Aboriginal culture and recorded in songlines for tens of thousands of years. But further clues to just how ancient this landscape is come from far beyond Earth: cosmic rays ...
Phys.org / First-time use of AI for genetic circuit design demonstrated in a human cell line
There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it takes for cells to behave in desired ways—for example, getting them to produce a therapeutic molecule ...
Phys.org / Rocks and rolls: The computational infrastructure of earthquakes and physics of planetary science
Sometimes to truly study something up close, you have to take a step back. That's what Andrea Donnellan does. An expert in Earth sciences and seismology, she gets much of her data from a bird's-eye view, studying the planet's ...
Phys.org / Do even low-mass dwarf galaxies merge? New clues from the outer stars of a Milky Way satellite
Using the Subaru Telescope's wide-field camera, astronomers have discovered a previously unknown structure surrounding a tiny satellite galaxy of the Milky Way. The newly discovered structure exhibits features resembling ...
Phys.org / Ancient teeth are treasure troves of data on Iron Age lifestyles
Teeth provide a wealth of information about the lives of Iron Age Italians, according to a study published in the open-access journal PLOS One by Roberto Germano of Sapienza University of Rome, Italy and colleagues.
Phys.org / A nanomaterial flex—MXene electrodes help OLED display technology shine, while bending and stretching
The organic light-emitting diode (OLED) technology behind flexible cell phones, curved monitors, and televisions could one day be used to make on-skin sensors that show changes in temperature, blood flow, and pressure in ...
Phys.org / Type Ia supernova delayed-detonation model supported by SN 2024gy observations
A research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with domestic and international partners, has carried out observational studies on SN 2024gy—a high-velocity Type ...
Phys.org / Ancient Tethys Ocean shaped Central Asia's landscape, study suggests
New research from Adelaide University suggests the power of the ancient Tethys Ocean might have shaped Central Asia's topography during the Cretaceous period.
Phys.org / Frozen hydrogen cyanide 'cobwebs' offer clues to origin of life
A substance poisonous to humans—hydrogen cyanide—may have helped create the seeds of life on Earth. At cold temperatures, hydrogen cyanide forms crystals. And, according to computer models reported in ACS Central Science, ...
Phys.org / Hydrogel cilia set new standard in microrobotics
Cilia are micrometer-sized biological structures that occur frequently in nature. Their characteristic high-frequency, three-dimensional beating motions (5–40 Hz) play indispensable roles inside the body.
Phys.org / Fire on ice: The Arctic's changing fire regime
The number of wildland fires burning in the Arctic is on the rise, according to NASA researchers. Moreover, these blazes are burning larger, hotter, and longer than they did in previous decades.
