Phys.org / Tiny oxygen gaps may determine whether next-generation memory films store data well
Researchers have captured in real time the "birth moment" when the performance of a next-generation memory material is determined. The key lies in controlling oxygen vacancies, microscopic defects created when oxygen atoms ...
Phys.org / Mirror-image molecules steer electron spins and lift perovskite solar cell efficiency
Some molecules come in two "handed" forms. This property, called chirality, can influence not only how molecules interact with light but also which electron spins they allow to pass. Researchers at the University of Osaka ...
Phys.org / The superconducting gap of an ultrathin nickelate defies expectations
Superconductors are materials that carry electrical current with zero resistance below a specific critical temperature. In conventional superconductors, the transition to superconductivity generally occurs at very low temperatures.
Tech Xplore / Nanoscale transistors achieve lower contact resistance with stepwise evaporation method
Metals, semiconductors and insulators are fundamental components of modern electronics. However, efforts to improve device performance have largely focused on semiconductor quality, while metal crystallinity has received ...
Phys.org / The discovery of the Great Barrier Reef's whale maternity ward
It started with a simple message: "This is the year to do something small for something huge." Now, 17 years later, the Whitsundays region has some of the best protection in the world for migrating humpback whales.
Tech Xplore / AI doesn't just play better chess—it manages complexity differently
For decades, chess has served as a laboratory for studying intelligence and decision-making. It is well established that today's chess engines can outperform even the strongest grandmasters. But far less is understood about ...
Medical Xpress / Immune cells that drive harmful autoantibody responses after COVID-19 identified
When the immune system encounters a virus, it produces antibodies designed to recognize and eliminate the invader. But in some people infected with SARS-CoV-2, the virus that causes COVID-19, the immune response goes awry, ...
Phys.org / Galápagos corals show El Niño events are more extreme now than in past 1,000 years
Temperatures have warmed dramatically across the equatorial Pacific Ocean in 2026, signaling the onset of a strong and potentially historic El Niño. These events can affect weather around the world, and the intensity of recent ...
Phys.org / Marker words suggest sharp rise in AI-assisted biomedical writing after ChatGPT
Up until two years ago, using large language models was still considered a special skill that everyone was encouraged to learn. Now, it is ubiquitous, especially in writing research papers that eventually become part of the ...
Phys.org / Roman telescope aims to directly image exoplanets 1,000 times fainter than current limits
The Roman Space Telescope is designed to directly image exoplanets using complex optomechanical systems developed by the Max Planck Institute for Astronomy
Phys.org / How AI‑powered policing is endangering the public's trust in police
Since the release of ChatGPT in 2022, artificial intelligence (AI) has dominated the cultural landscape. Uptake across various sectors, including law enforcement, quickly followed, usually with minimal foresight and little ...
Phys.org / Utah mountain ranges may store a billion tons of hidden ice
Unlike conventional glaciers, rock glaciers appear as piles of rock that obscure large masses of unaccounted-for ice. Rock glaciers are common in the Wasatch and Uinta ranges, even appearing on the Colorado Plateau in the ...
