Phys.org / Dark matter cannot be ruled out as cause of gamma ray glow at the Milky Way's center, machine learning shows
An international research collaboration between the University of Vienna and Lawrence Berkeley National Laboratory in the United States has used machine learning to re-examine one of the most debated signals in astrophysics. ...
Phys.org / One of the world's most important plate boundaries is older than previously thought
A chain of remote islands and underwater volcanoes between Alaska and Kamchatka has revealed a much older chapter in Earth's tectonic history than previously known. Along the Aleutian Arc, the Pacific Plate dives beneath ...
Phys.org / Frozen Greenland middens preserve 4,500 years of farms, seal hunts and toilets
Greenland has a long and checkered history of human settlement: several Paleo-Inuit cultures since approximately 2,500 BCE, descendants of Vikings between the 10th and 15th centuries, and early modern Danes since 1721. All ...
Phys.org / Thermochemical mantle plume identified as the likely origin of Earth's largest oceanic plateau
The Ontong Java Plateau in the western Pacific Ocean is the largest oceanic plateau on Earth, and its formation mechanism has not been well understood.
Phys.org / Toxic algal blooms linked to deaths of recently stranded humpback whales
Marine mammal stranding teams have completed major response activities for two deceased juvenile humpback whales discovered less than 10 miles (16 kilometers) apart in Monterey Bay earlier this month and issued preliminary ...
Dialog / 'Contaminated' cultures: Can conservation protect nature while excluding Indigenous peoples?
At an international heritage symposium in Japan, I heard a word that stayed with me: "contaminated." The discussion concerned whether Indigenous peoples needed to be named explicitly in a new World Heritage framework. One ...
Phys.org / Real-time microscopy reveals how semiconductor nanowires grow, and how bismuth seeds can speed their formation
Scientists from the National Graphene Institute at the University of Manchester and Sun Yat-sen University have captured the growth of semiconducting tellurium nanostructures in liquid in real time, revealing how tiny seed ...
Phys.org / Messi or Ronaldo? Your political ideology may play a part
Whether someone prefers Lionel Messi or Cristiano Ronaldo—arguably two of the world's greatest footballers today—may be associated with their political outlook, according to the results of an international survey led by Nanyang ...
Tech Xplore / Simple coating could make next-generation chip transistors easier to manufacture without damaging ultrathin layers
Inside computer chips are billions of tiny transistors made from silicon. But the material is approaching its limits. In an effort to build smaller, more capable devices, researchers are exploring how they might build transistors ...
Medical Xpress / Teenagers whose parents are more distracted by phones may be more insecure
We worry about the time kids spend using screens—but what if the time their caregivers spend on phones is also harmful? Scientists working on digital mental health noticed increasing reports of teenagers struggling with their ...
Phys.org / Devoted dads and citizen science: The evolution of parental care in harvestmen spiders is uncovered
Citizen science data from the popular platform iNaturalist has helped uncover the evolution of parental guarding behavior in harvestmen spiders, as shown in research published in the Zoological Journal of the Linnean Society.
Medical Xpress / Colorectal tumors use mitochondrial complex II to stockpile iron, but eliminating it causes cell death
Scientists know that colorectal cancer cells require large amounts of iron and that as cancer becomes more aggressive, the cells have even higher amounts of iron. Normal cells with high levels of iron would undergo a type ...
