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 / 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 / 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 / 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 ...
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 / 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 / MLB swing-tracking data helps researchers examine baseball's long-debated two-strike approach
When baseball fans watch a batter strike out with runners in scoring position, the reaction is often immediate: Shorten the swing. Put the ball in play. Stop swinging for the fences, they lament.
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 / 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 / Rocket launches and reentries harm Earth's ozone layer
The space industry is surging. In coming years, nearly 10,000 spacecraft are slated to launch into low-Earth orbit for a variety of purposes, such as global surveillance, space tourism, and satellite "megaconstellations" ...
Phys.org / Van der Waals forces can play unexpected role in thin film properties
Researchers have demonstrated the ability to use van der Waals forces to tune the physical and electronic properties of ferroelectric thin films. The work opens the door to new techniques for engineering materials for use ...
Phys.org / Chemists unlock first total synthesis of rare plant alkaloid tied to anticancer activity
Plants are undeniably one of nature's most promising sources of new medicines, with monoterpenoid indole alkaloids (MIAs) being a great example. Some intricate compounds are built from multiple-linked chemical units that ...
