Phys.org / A supermassive black hole erupted in X-rays, and its radio jets followed 300 days later
By combining roughly two decades of observations from NASA's Swift X-ray Telescope with radio monitoring, astronomers have caught a supermassive black hole at the heart of the Perseus Cluster suddenly flaring in X-rays, and ...
Tech Xplore / A new kind of AI that does its thinking cheaply without words
There may soon be a new kind of artificial intelligence in town, one that uses a novel approach to thinking that could save massive amounts of computing power and money.
Phys.org / Iguanodon shinbone growth may be first evidence of an infected skin ulcer in a dinosaur
Fossilized bones can reveal a wealth of details about animals, including their size, appearance, what they ate and any injuries they may have suffered. In a paper published in the journal Royal Society Open Science, researchers ...
Phys.org / How algorithms are making our environments bland
The Pantone color of the year for 2026 is white. It's called Cloud Dancer, which is described as a "lofty white." This choice reflects a growing trend away from color in our visual world.
Medical Xpress / Cannabis edibles can impair driving, even with blood THC below legal limits
The feeling of being "high" on cannabis primarily comes from its psychoactive compound, delta-9-tetrahydrocannabinol, or THC. Alongside it is its more subdued companion, cannabidiol (CBD), often used for its potential therapeutic ...
Phys.org / How Mercury formed its graphite crust and core
As the BepiColombo mission prepares to enter the final phase of its journey to Mercury, a series of studies conducted by researchers at the University of Liège and KU Leuven sheds new light on the early stages of the evolution ...
Medical Xpress / Rethinking radiotherapy may boost immunotherapy for pancreatic cancer
Pancreatic cancer remains one of the most aggressive malignancies, with a particularly poor prognosis even when diagnosed at a localized stage. In a paper published in Nature Reviews Gastroenterology & Hepatology, researchers ...
Tech Xplore / Why adding AI agents to a system sometimes reduces its performance
Computer scientists worldwide have been developing a wide range of artificial intelligence (AI) systems. Some of these systems rely on an individual AI agent, while others consist of multiple interacting agents that exchange ...
Medical Xpress / Early mitochondrial stress reveals potential mechanism for lasting heart protection
Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do much more—including acting as signaling hubs. Some signals that mitochondria send can reprogram the activity of the entire ...
Phys.org / Virus-like particles enable gene activity tracking over time in the same cells
In recent years, scientists have developed methods to measure a cell's transcriptome, or all the RNA produced by a cell, to study the cell's identity and genetic activity. However, these methods rely on killing the cell to ...
Phys.org / Germany's Isar Aerospace launches rocket into orbit from Norway
Germany's Isar Aerospace launched a rocket into orbit from Norway on Saturday as Europe races to boost its ability to economically send satellites into space independently of the United States.
Phys.org / Antarctic expedition reveals why Southern Ocean clouds remain one of climate science's greatest challenges
The Southern Ocean plays a pivotal role in regulating Earth's climate, yet the clouds that blanket this remote region remain among the least understood features in atmospheric science. By controlling both incoming sunlight ...
