Phys.org / Seabirds trade their own survival to raise more chicks after energy-intensive breeding seasons
Wild seabirds that face high energy demands during the breeding season go on to migrate farther and raise more chicks the next year, but at a cost to their own survival. An international team led by researchers from Nagoya ...
Phys.org / Low-level cloud loss amplifies global warming, simulations suggest
Low-level clouds over Earth's oceans play a prominent role in keeping our planet cool by reflecting sunlight away from the surface. But their response to climate change has been hard to model. Now, researchers at Caltech ...
Phys.org / Highly tunable electro-optic isolator achieves one-way light flow on photonic chips
Integrated photonic devices—tiny circuits that use light instead of electrons—are becoming increasingly important for scalable photonics technologies and high-bandwidth communications. They are particularly valuable for managing ...
Phys.org / Seven possible quasar lenses emerge from AI scan of 800,000 DESI objects
Quasars, distant cores of galaxies powered by supermassive black holes, are among the most luminous objects in the universe. While not uncommon, their brightness can make it difficult to accurately measure the galaxies they ...
Phys.org / Simple semiconductor films break light's front-back symmetry
Light typically interacts with a material the same way whether it enters through the front or the back—like polarized sunglasses that work the same from either side. Cornell researchers have demonstrated a simple route to ...
Phys.org / New quantum chip architecture could use built-in vibrations to link distant qubits
A new concept from Warwick researchers could help solve one of the biggest challenges to building large-scale quantum computers: enabling communication between vast numbers of quantum bits (qubits) over long distances across ...
Phys.org / Scientists pinpoint where cells first begin copying DNA
Researchers at the MRC Laboratory of Medical Sciences (LMS) and collaborators have uncovered one of the earliest steps in DNA replication: the moment a cell first opens its DNA to begin making a copy of its genome. The findings, ...
Phys.org / Mercury reveals short-lived radiation belts during its swing farther from the sun
Mercury was long considered the exception to the rule that magnetic planets have radiation belts similar to Earth's Van Allen belts, but a new study by University of Michigan Engineering and the University of California, ...
Phys.org / Long-term study finds widespread lithium in drinking water across communities in the western U.S.
Lithium in drinking water is a widespread and persistent source of human exposure across Tribal communities in the Western United States, according to a new study from Columbia University Mailman School of Public Health. ...
Phys.org / Molecular switch that activates cell growth signaling may offer more precise route for anticancer therapy
Cells carry their own growth switches. When enough nutrients—amino acids in particular—are available, cells flip this switch on and begin to grow. Researchers at KAIST and Yonsei University have uncovered the molecular mechanism ...
Phys.org / Membrane nanostructures reshape in water, revealing route to better ion transport
Next-generation energy devices like fuel cells and water electrolyzers depend on ion-exchange membranes that allow only water and certain ions to pass through.
Phys.org / California wildfire damage risk map uses factors most closely linked to severe property losses
By analyzing 100,000 California Department of Forestry and Fire Protection inspection records from 2013 to 2024, researchers at the University of California, Irvine have identified the key environmental and human factors ...
