Phys.org / Reconfigurable Ge-Si photodetector achieves ultrahigh-speed data transmission using low-loss packaging
The rapid growth of large language models is placing increasing demands on data centers, where large volumes of data must be transferred efficiently between servers. Optical interconnects are essential for enabling this communication, ...
Phys.org / MatterChat model helps AI to 'see' the language of atom-scale physics to sharpen materials predictions
From writing emails to generating computer code, much of the artificial intelligence prevalent in our daily lives has succeeded by mastering one domain: text. However, this leaves a major blind spot in the physical sciences, ...
Phys.org / Supernova dust may be behind one of JWST's biggest puzzles
Astronomers may have found an explanation for one of the biggest mysteries revealed by the James Webb Space Telescope (JWST): why so many galaxies in the early universe appear unexpectedly bright in ultraviolet light. The ...
Phys.org / Ultrafast switching device unlocks low-power optical-to-electrical conversion for AI hardware
Modern energy demands are soaring as technologies like AI and IoT become more common, and researchers have been working hard to develop hardware that can keep up. Now, a team of researchers from the University of Tokyo has ...
Phys.org / White hydrogen discovered in billion-year-old Canadian Shield rock points to potential new energy source
Within the Canadian Shield, hydrogen gas is steadily building up naturally among some of the oldest rocks on Earth. Now, for the first time, geochemists at the University of Toronto and the University of Ottawa have measured ...
Phys.org / AI-generated fake citations are flooding scientific literature across publications, scientists warn
The citations at the end of a research paper should represent a solid foundation of existing knowledge about a particular field, a pool of peer-reviewed sources built over years of research and study. However, with the increasing ...
Phys.org / Debunking a core chemistry concept taught in classrooms everywhere
A new study has revealed that a core idea taught in chemistry classrooms around the world may be wrong. Dr. Edwin Johnson, Lecturer at the University of Newcastle, co-authored the paper published in the Journal of Chemical ...
Phys.org / A physicist's fresh look at the 'prisoner's dilemma' reveals hope for cooperation
The "prisoner's dilemma" is one of the most famous ideas in game theory. For decades, this game has been used to explain why selfishness often beats cooperation. In the prisoner's dilemma, two players can either cooperate ...
Phys.org / Intensifying droughts may be pushing tropical forests toward a dangerous threshold
Tropical forests, often described as the lungs of the planet, may be edging closer to a dangerous threshold as droughts become more frequent and widespread across the world's humid tropics. New research suggests these ecosystems ...
Phys.org / Twisted WSe₂ reveals elusive charge-neutral quantum modes
Quantum materials, materials with properties that are influenced by the laws of quantum mechanics, have attracted considerable attention over the past few decades. Their unique properties make these materials advantageous ...
Phys.org / Ancient Arctic fossils uncover three mammal species that survived months of darkness
Today's Arctic may feel remote and desolate, but more than 70 million years ago, it was a surprisingly lively place for some of Earth's ancient mammals.
Phys.org / Findings reconsider the existence of Europa's vapor plumes
Looking back at 14 years of Hubble telescope data for Jupiter's moon Europa has given Southwest Research Institute (SwRI) scientists a better understanding of its tenuous atmosphere. The findings have cast doubt on previous ...
