Phys.org / People overestimate how confident AI systems are in their responses, experiments reveal
Artificial intelligence (AI) systems, particularly conversational agents such as ChatGPT or Gemini, are now used daily by a growing number of people worldwide. While many users trust the answers of AI agents to their queries, ...
Phys.org / Nondestructive DNA sampling reveals 1,300 years of secrets in historic parchments
Researchers have demonstrated a nondestructive way to collect cellular material from historical parchment manuscripts, allowing them to conduct genetic analyses that offer new insights into everything from trade routes to ...
Phys.org / Ancient burial practices emerge from Laos' mysterious Plain of Jars
Hundreds of stone jars, some weighing several tons, are scattered across the remote uplands of northern Laos. Despite being researched for nearly a century, their purpose remains uncertain. "Archaeologists generally agree ...
Phys.org / Kenya's new poaching problem: Smuggling Giant Harvester Ants
Kenyan ant expert Dino Martins gushes over the red and black insects that have become the center of an international smuggling trade.
Phys.org / Galactic collision may have reset Milky Way disk 11 billion years ago
A new study led by researchers at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC) reveals how the disks of galaxies like the Milky Way are affected ...
Phys.org / Careful crystallization unlocks well-ordered perovskite layers for transistors
Perovskites are a class of materials with a unique crystal structure that suits applications such as fabricating solar cells, light-emitting diodes and transistors. However, molecules in thin layers often cannot arrange themselves ...
Phys.org / Mapping how 'Big AI' influences AI laws and oversight
Artificial intelligence (AI) companies influence policy and regulation using similar techniques to Big Tobacco, Big Pharma and Big Oil, according to a new study.
Phys.org / eROSITA discovers a 'changing-look' Seyfert galaxy
Astronomers have tracked a dramatic "changing-look" active galactic nucleus (AGN) whose central supermassive black hole appeared to switch off and then rapidly reignite. The galaxy, HE 1237−2252, dimmed in X-rays by a factor ...
Phys.org / Neutrino flavor flips could be key to triggering supernovae
Despite being so elusive, neutrinos are produced in abundance in some of the most violent events in the universe. One of their strangest properties is that they can spontaneously switch between three types, or "flavors": ...
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 / From wetland sediment, scientists uncover centuries of climate chaos—and human resilience
The climate of the ancient Eastern Mediterranean was far more turbulent than previously thought—and a new study suggests that people adapted anyway. An international team of scientists, spearheaded by UC San Diego's Center ...
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, ...
