Tech Xplore / The friendlier AI gets, the more it can backfire
Major AI platforms, including OpenAI and Anthropic, as well as social apps like Replika and Character.ai, are increasingly designing chatbots to be warm, friendly, and empathetic. However, new research from the Oxford Internet ...
Tech Xplore / What are the reasons for traffic jams? Whether traffic flows or not depends on more than just the roads
If a city's suburban railway network is expanded, additional flats are likely to be built in an agglomeration that is better connected as a result. The opposite also holds true: If new buildings spring up like mushrooms in ...
Phys.org / Simulations predict ground motion for earthquakes on Bay Area's Hayward fault
The Hayward fault, part of the larger San Andreas fault system, runs 74 miles through the East Bay of the San Francisco Bay Area. The fault is overdue for an earthquake that could cause extensive damage to such a dense population ...
Medical Xpress / New dual-target drug may help overcome immunotherapy resistance in pancreatic cancer
Pancreatic ductal adenocarcinoma is one of the deadliest cancer types, with a five-year survival rate of 13%. There are only two treatment regimens available with limited efficacy. Pancreatic cancers do not respond to immunotherapy ...
Medical Xpress / Mechanical forces from the beating heart may help prevent cancer cell growth
Scientists may have discovered another way the human body tries to protect itself from cancer. New research on mice suggests that the heart's constant beating may prevent tumor growth in cardiac tissue. Most organs are vulnerable ...
Medical Xpress / New medical guidelines urge more fiber, less bathroom scrolling on your phone
On Wednesday, the American Gastroenterological Association (AGA) released updated guidelines aimed at modern bathroom habits and dietary trends that could be making hemorrhoids and constipation worse.

Between December 2024 and February 2025, 10 newborns with hypoxic-ischemic brain injury were treated with breast milk administered through the nasal passages using a special method at Semmelweis University in Budapest. A ...
Phys.org / This ultracold quantum device turns electricity into something far stranger that could unlock sound-based lasers
Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at extremely cold temperatures. The technology could be used to create phonon lasers, with possible applications ...
Phys.org / 'Ruthless predator' of red tide plankton reveals unusual bioluminescence
Scientists at UC San Diego's Scripps Institution of Oceanography have uncovered new insights into the bioluminescence of a unique species of marine plankton that feeds on other plankton, including the harmful algae responsible ...
Phys.org / 'Aquila Booster' challenges theoretical limits of particle acceleration in pulsar wind nebulae
The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind nebula powered by PSR J1849-0001 in the constellation Aquila, marking the discovery of a new PeVatron ...
Phys.org / Why rainfall remains hard to predict in a warming world
A new study led by the University of Oxford and ETH Zurich reveals that a key part of the climate system—the large-scale wind patterns that determine where rain falls—can be underestimated by current climate models, helping ...
Phys.org / Overcoming the algorithmic gender bias in AI‑driven personal finance
Artificial intelligence is transforming our world and financial services are no exception. AI is reshaping the personal banking sector, but where does it currently stand on gender parity, transparency, and fairness?
