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 / 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 / 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 / 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 / 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 / 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.
Phys.org / AI tools are expanding individual capabilities while contracting scientific attention, research finds
Artificial intelligence promises to accelerate scientific discovery and open new frontiers of inquiry. But new research from James Evans (Faculty Co-Director of Novel Intelligence; Max Palevsky Professor of Sociology & Data ...
Phys.org / Crop droughts set to worsen—even as rainfall increases
Europe and western North America will experience more frequent and severe crop droughts as Earth warms, even in places where yearly rainfall increases.
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 / From bolts to blue jets, lightning comes in many strange forms
Lightning has captured people's fascination for millennia. It's embedded in mythology, religion and popular culture. Think of Thor in Norse mythology or Indra in Hinduism.
