Phys.org / Heavily reddened quasars caught going through a 'blow-out' phase
At the center of most large galaxies sits a supermassive black hole (SMBH). When these black holes are actively consuming material, they become incredibly luminous quasars. But some quasars appear wrapped in thick clouds ...
Phys.org / 'Patchwork families' existed more than 5,000 years ago, Neolithic DNA reveals
Children from previous relationships growing up as siblings in a new family, couples adopting or fostering children: So-called patchwork families are a widespread way of life today. It is considered modern, but is in fact ...
Phys.org / Honeybees reveal Weber's law in flight when choosing paths
Honeybees are among the widely studied insects, due to their sophisticated, hierarchical social organization and their essential ecological role. Bees can move swiftly in natural environments, passing through narrow openings ...
Phys.org / Controlled experiments reveal how nuclear fallout particles form
In less than a millionth of a second after a nuclear detonation or a severe nuclear reactor accident, an enormous burst of energy heats the surrounding air and materials. Everything in the vicinity is vaporized into a hot, ...
Phys.org / 'Permanently wet' coating method could transform wastewater treatment by helping bacteria survive better
Living bacteria embedded in coatings could clean wastewater, capture carbon and generate biofuels—but only if they survive the manufacturing process. Researchers at the University of Surrey and the University of Warwick have ...
Phys.org / The first signs of human cremation may date back 100,000 years
The latest discoveries by an international research team, which includes Academy Research Fellow Ferhat Kaya from the University of Oulu, Finland, offer a detailed view of how early humans lived, moved, and adapted to their ...
Phys.org / Quantum metasurface boosts terahertz detection sensitivity by exploiting in-plane photoelectric effect
Being able to see light and detect radiation is of utmost importance at any frequency. While this challenge has been solved in the visible range, radiation detectors in the far-infrared and terahertz regimes are either not ...
Phys.org / Saturday citations: Two T. rexes and new exercise guidance that scientists are not calling 'easy'
John Hammond voice: "Welcome... to Saturday Citations." We're talking about different types of T. rexes today, along with some unwelcome news about cardiovascular health, but this week also brought news about the connection ...
Phys.org / SpaceX launches its biggest, most beefed-up Starship yet on a test flight
SpaceX launched its biggest, most powerful Starship yet on a test flight Friday, an upgraded version that NASA is counting on to land astronauts on the moon.
Phys.org / AI makes a major breakthrough in a math problem that had stumped experts for decades
For nearly 80 years, mathematicians have struggled to solve a classic geometry puzzle first posed by Paul Erdős in 1946: the planar unit distance problem. The question posed by the legendary Hungarian mathematician was, on ...
Phys.org / Astronomers discover a super-Earth orbiting a nearby red dwarf
Astronomers from Italy and Brazil have investigated a nearby red dwarf star known as Ross 318 and have discovered an exoplanet orbiting this star, which is at least six times more massive than Earth. The discovery is reported ...
Phys.org / Hi-res microscopes give biologists petabytes of data. Scientists are creating an AI assistant to make sense of it
In a cramped, windowless room on the University of California, Berkeley, campus, two bespoke microscopes—each a Swiss Army knife for high-resolution imaging—operate around the clock gathering data that will help train a game-changing ...
