Phys.org / How the Mayans were able to accurately predict solar eclipses for centuries
The Maya Civilization, from Central America, was one of the most advanced ancient civilizations, known for its significant achievements in astronomy and mathematics. This includes accurate calendars and detailed celestial ...
Phys.org / Google claims its latest quantum algorithm can outperform supercomputers on a real-world task
Researchers from Google Quantum AI report that their quantum processor, Willow, ran an algorithm for a quantum computer that solved a complex physics problem thousands of times faster than the world's most powerful classical ...
Medical Xpress / Successful experiments reprogram rogue T cells for targeted autoimmune disease therapy
Two teams of researchers have developed a cell reprogramming technology that converts rogue disease-causing T cells from our immune system into protective Tregcells. These cells help ensure that the immune system doesn't ...
Tech Xplore / AI teaches itself and outperforms human-designed algorithms
Like humans, artificial intelligence learns by trial and error, but traditionally, it requires humans to set the ball rolling by designing the algorithms and rules that govern the learning process. However, as AI technology ...
Phys.org / A tiny chip that can help us see deeper into space
A new imaging system could help us see deeper into the universe than ever before. The same powerful technology could also help us analyze the chemical makeup of everyday materials such as food and medicines much faster and ...
Phys.org / Antarctic ice reveals two volcanoes erupting simultaneously may have caused 15th-century cooling
Nearly 600 years ago, a massive volcanic eruption sent clouds of sulfurous gas and ash high into the atmosphere. The blast known as the 1458/59 CE event was so huge that it triggered decades of cooling, especially in the ...
Tech Xplore / New air filter could turn every building into a carbon sink
Despite decades of warnings and increasing efforts to fight climate change, global carbon emissions are still rising. While cutting emissions from the source is a common way we address this problem, another crucial strategy ...
Phys.org / Dust from far side of the moon could reveal more about origin of water in our solar system
Dust brought back to Earth by China's Chang'e-6 mission contains rare meteorite relics that could change our understanding of sources of water and other life-essential ingredients in our solar system.
Tech Xplore / Scientists create a novel hydrogel for unclonable security tags
Encryption technologies are vital in today's digital landscape to protect sensitive information from hackers and prevent fraud. While cutting-edge encryption has been developed for data, sophisticated protection for physical ...
Phys.org / New chemical treatment turns deadly arsenic contaminant into a valuable raw material
Arsenic is a natural component of Earth's crust and highly toxic in its inorganic form. The element is a cause of a global public health crisis, as it is present in groundwater and the drinking water consumed daily by millions ...
Phys.org / Follow-up observations by Webb confirm GRB 250702B is most energetic cosmic explosion ever recorded
Considering the immense size of the universe, it's no surprise that space still holds plenty of secrets for us. Recently, astronomers believe they stumbled upon a kind of cosmic blast never seen before, and it's challenging ...
Tech Xplore / Transparent wearable monitor gives real-time warnings about overexposure to sunlight
Scientists in South Korea have unveiled a transparent, wearable sensor that monitors a user's exposure to ultraviolet A (UVA) radiation in real-time. The technology could help prevent sunburn and long-term skin damage that ...
Phys.org / How poisonous glands helped modern toads conquer the world
Modern toads (Bufonidae) are among the most successful amphibians on the planet, a diverse group of more than 600 species that are found on every continent except Antarctica. But just how did they conquer the world? An international ...
Tech Xplore / The way we talk to chatbots affects their accuracy, new research reveals
Whether we're seeking customer support, looking for recommendations, or simply asking a quick question, AI chatbots are designed to give us the answers we're looking for. But there's more going on beneath the surface. Every ...
Phys.org / Discovery of four stone megastructures could change our view of prehistoric societies
Scientists have discovered evidence of stone megastructures on the Karst Plateau on the border of Slovenia and Italy that were most likely built before the Late Bronze Age. These enormous structures have long, low walls that ...
