Phys.org / Myth of Native Hawaiians causing bird extinctions debunked by study
Challenging a 50-year-old narrative about Hawaiʻi's native birds, a new study from the University of Hawaiʻi at Mānoa found no scientific evidence that Indigenous People hunted waterbird species to extinction. Published ...
Phys.org / Urban soils get new life by mixing excavated dirt with organic waste
Excavated soil from construction sites usually ends up in landfills, but it has great potential. Researchers at the Technical University of Munich (TUM) show how excavated soil can be enriched with organic waste so that it ...
Phys.org / Melting glaciers may mix up waters more than we thought
As marine-terminating glaciers melt, the resulting freshwater is released at the seafloor, which mixes with salty seawater and influences circulation patterns. As the oceans warm, it's growing increasingly important to study ...
Phys.org / A dry surface thanks to fluid physics: Contact-free method gently remove liquids from delicate microstructures
Researchers at the University of Konstanz have developed a gentle, contact-free method to collect liquids and remove them from microscopic surface structures. The method uses vapor condensation to generate surface currents ...
Phys.org / Marine sediments suggest glaciers retreated in sync across both hemispheres
An international team of scientists has uncovered evidence glaciers in the Southern and Northern hemispheres were synchronous during the last ice age.
Phys.org / Sailboat measurements improve estimates of ocean CO₂ uptake
During training cruises and regattas, sailors collect valuable data for climate research at sea. A study appearing in Science Advances showed that this data can help improve estimates of the marine carbon sink.
Phys.org / This crystal sings back: Study sheds light on magnetochiral instability
Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported the first observation of a dynamic magnetochiral instability in a solid-state material. Their findings, published ...
Phys.org / 'Nu' citation index may bridge gap between productivity and impact metrics
Researchers propose a new citation index that balances productivity and impact in academic publishing. The h-index of citations was introduced in 2005 by physicist Jorge E. Hirsch. This index is defined simply as the maximum ...
Phys.org / Complex life on planets orbiting the galaxy's most common stars may be unlikely
In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy.
Phys.org / Persistent shock wave around dead star puzzles astronomers
Gas and dust flowing from stars can, under the right conditions, clash with a star's surroundings and create a shock wave. Now, astronomers using the European Southern Observatory's Very Large Telescope (ESO's VLT) have imaged ...
Phys.org / Sinking boreal trees in the deep Arctic Ocean could remove billions of tons of carbon each year
Global efforts to reduce pollution will not be enough to mitigate the worst effects of climate change, scientists say. We will also need to extract over 10 gigatons of carbon dioxide from the atmosphere every year for the ...
Phys.org / Atom-thin, content-addressable memory enables edge AI applications
Recent advances in the field of artificial intelligence (AI) have opened new exciting possibilities for the rapid analysis of data, the sourcing of information and the generation of use-specific content. To run AI models, ...
