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 / 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 / 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 / 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 / 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 / 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 ...
Dialog / A 170 km journey by a freshwater stingray challenges long-held conservation assumptions
Most sharks and rays inhabit the oceans, but a small proportion thrive in freshwater. Approximately 4% to 5% of all shark and ray species live in tropical and subtropical rivers around the world. Two main ecological strategies ...
Phys.org / Neutron star merger simulations gain new precision with AI-driven r-process heating
Using a novel simulation model based on machine learning, an international research team at GSI/FAIR has succeeded in gaining a deeper understanding of element formation in stellar events such as neutron star mergers. For ...
Phys.org / Alien signal claims face stricter verification under updated disclosure rules
The IAA SETI Committee has updated rules for evaluating and revealing the detection of extraterrestrial intelligence.
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 ...
Phys.org / How plants survive constant DNA damage: Newly identified repair protein protects growth-critical stem cells
Similar to the way DNA damage can contribute to human diseases such as cancer, it can also disrupt growth, development and survival in plants. Every day, plants endure environmental stresses such as sunlight, radiation, drought ...
Phys.org / NASA satellites reveal major ocean nutrient stress
A new study combining NASA satellite observations, ocean surveys and genetic testing of marine microorganisms found evidence that warming ocean waters may be limiting nutrient availability across much of the global ocean. ...
