Phys.org / Scientists detect lithium in Mercury's exosphere using magnetic wave analysis
Using a cutting-edge magnetic wave detection technique, a new study in Nature Communications has identified lithium in Mercury's exosphere for the first time.
Phys.org / First sperm whale tooth from 3rd millennium Iberian peninsula discovered
A team of researchers, led by Dr. Samuel Ramírez-Cruzado Aguilar-Galindo, recently provided a comprehensive, multidisciplinary study of a sperm-whale tooth found in the Copper Age mega-site of Valencina de la Concepción-Castilleja ...
Phys.org / Study reveals hidden regulatory roles of 'junk' DNA
A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic "junk," may actually play powerful roles in regulating gene expression. Focusing on a family of sequences ...
Phys.org / Deep life's survival secret: Crustal faulting generates key energy sources, study shows
Chinese researchers have recently challenged the long-held belief that "all life depends on sunlight." In a study published in Science Advances, the researchers identified how microbes in deep subsurface areas can derive ...
Phys.org / How Google's Android earthquake detection system can save lives
If you're in an earthquake-prone area and own an Android phone, it could save your life. It may even have already done so. The Android Earthquake Alert (AEA) system, which began in the U.S. in 2020 and has since expanded ...
Phys.org / AI-assisted sorting, other new technologies could improve plastic recycling
Just 9% of plastic worldwide is recycled. Due to waste mismanagement, nearly three-quarters of it ends up in landfills or the environment.
Phys.org / The first observation of a giant nonlinear Nernst Effect in trilayer graphene
The generation of electricity from heat, also known as thermoelectric energy conversion, has proved to be advantageous for various real-world applications. For instance, it proved useful for the generation of energy during ...
Phys.org / Ecosystem collapse patterns mirror magnetic material behavior under stress
A new study published in the journal One Earth reveals that the way ecosystems collapse—abruptly or gradually—may depend on internal complexity, much like how magnetic materials behave under stress.
Phys.org / Common feature between forest fires and neural networks reveals universal framework
Researchers from the University of Tokyo in collaboration with Aisin Corporation have demonstrated that universal scaling laws, which describe how the properties of a system change with size and scale, apply to deep neural ...
Phys.org / New York City intersections see one-third fewer pedestrian injuries with longer head-start intervals
Giving pedestrians a 7-second head start at traffic lights—known as Leading Pedestrian Intervals (LPIs)—is associated with a 33% reduction in total pedestrian injuries—both fatal and non-fatal—at New York City intersections, ...
Phys.org / Scanning tunneling microscopy reveals subsurface atomic structure
Scientists use scanning tunneling microscopy to understand how a material's electronic or magnetic properties relate to its structure on the atomic scale. When using this technique, however, they can normally investigate ...
Phys.org / Why do we need sleep? Researchers find the answer may lie in mitochondria
Sleep may not just be rest for the mind—it may be essential maintenance for the body's power supply. A new study by University of Oxford researchers, published in Nature, reveals that the pressure to sleep arises from a ...
