Phys.org / Astronomers discover the earliest known flickering quasar
A supermassive black hole lies at the heart of every galaxy, including the Milky Way. When a black hole is active, it pulls material in as a whirlpool of high-temperature gas and dust. As this cosmic material piles up and ...
Phys.org / How Artemis II livestreamed hi-def videos and images from the moon to Earth
This April, humanity had front-row seats to space as the Artemis II Orion spacecraft transmitted crystal-clear footage of its historic journey around the moon from more than 250,000 miles (about 402,000 kilometers) back to ...
Phys.org / Superheated magma may explain why similar volcanoes erupt in very different ways
Scientists have shed light on a thermal process in magma that may help explain why similar volcanic systems can produce very different eruptive behaviors.
Phys.org / 50 years of data reveals true extent of climate change impacts on kelp forests
New research from the University of Victoria (UVic) has found that some kelp forests around Vancouver Island were disappearing far earlier than scientists previously thought, highlighting that climate change has been altering ...
Phys.org / Medicinal plants yield carbon nanoparticles that glow red and flag toxic metals
What do iron, lead and nickel have in common? These heavy metals are an indispensable part of many industries. However, they also share a dark reality: They are serious environmental and public health threats. Every day, ...
Phys.org / Cosmic bombardment may have opened Earth's crust for prebiotic chemistry
Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of ...
Phys.org / Headless skeletons offer new insights into farming societies 7,000 years ago
Dozens of human skeletons, lying apparently randomly on and next to each other, with their skulls missing, present a terrifying sight at first glance. Since 2022, this is what researchers have been excavating in a 7,000-year-old ...
Phys.org / Antibiotics drive resistance in waterways—even after they break down
Antibiotics continue to drive resistance in bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first ...
Phys.org / DNA design unlocks nanometer-scale catalyst control for cleaner hydrogen production
The fixed idea that DNA is only a molecule that stores genetic information is being challenged. KAIST researchers have developed a technology that controls the chemical environment around catalysts at the nanometer scale ...
Phys.org / Bacteria can learn and form memories without a brain
Researchers at Carnegie Mellon University have shown that bacteria can learn from past experiences, store memories across generations and adapt their behavior to changing environments, all without a brain or nervous system. ...
Phys.org / X-ray scans uncover Nazi symbols hidden beneath postwar painting
Erich Mercker (1891–1973), a painter from Munich, was quite successful in his day. Between 1933 and 1945, he painted works containing Nazi symbolism, including "Die Stätte des 9. November," which depicts the Feldherrnhalle ...
Phys.org / Cloud-tested quantum noise model predicts superconducting qubit errors with sevenfold better accuracy
Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore have developed a practical, comprehensive noise-modeling framework for a popular class of ...
