Phys.org / Ancient Alaskan site may help explain how the first people arrived in North America
New evidence has emerged that sheds light on the possible first people to populate the Americas. Dating of stone and ivory tools found at an archaeological site in Alaska suggests that these early pioneers traveled through ...
Tech Xplore / China ramps up energy boom flagged by Musk as key to AI race
New data on China's relentless energy installations underscore warnings from Elon Musk and Jensen Huang that the nation's world-beating power network will deliver a major advantage over the U.S. in the race to dominate artificial ...
Medical Xpress / A 3D-printed delivery system enhances vaccine delivery via microneedle array patch
The COVID-19 pandemic highlighted an urgent need for efficient, durable, and widely accessible vaccines. This prompted several important innovations in vaccine technology, and researchers continue to explore new and creative ...
Phys.org / Detection system uses gravitational waves to map merging black holes
An international collaboration of astrophysicists that includes researchers from Yale has created and tested a detection system that uses gravitational waves to map out the locations of merging black holes—known as supermassive ...
Phys.org / Solid, iron-rich megastructure under Hawaii slows seismic waves and may drive plume upwelling
Mantle plumes beneath volcanic hotspots, like Hawaii, Iceland, and the Galapagos, seem to be anchored into a large structure within the core-mantle boundary (CMB). A new study, published in Science Advances, takes a deeper ...
Phys.org / When gigantism shapes the diet of a superpredator: The Japanese giant salamander's spectacular transition
A study conducted by researchers at the University of Liège on a large population of Japanese giant salamanders—one of the largest amphibians in the world—reveals that above a certain size, a spectacular transition occurs ...
Medical Xpress / Statins do not cause the majority of side effects listed in package leaflets, large-scale analysis finds
Statins do not cause the majority of the conditions that have been listed in their package leaflets, including memory loss, depression, sleep disturbance, and erectile and sexual dysfunction, according to the most comprehensive ...
Phys.org / Unlocking the 'black box' of Grand Canyon's water supply
Every year at Grand Canyon National Park, millions of visitors from all over the world stop at one of a dozen water spigots. Most people are on a rim, seeing the canyon's majesty for the first time, when they step off the ...
Phys.org / JWST discovers a new extremely metal-poor dwarf galaxy
Using the James Webb Space Telescope (JWST), astronomers have discovered a new dwarf galaxy, which received designation CAPERS-39810. Further investigation of CAPERS-39810 revealed that it is an extremely metal-poor galaxy. ...
Medical Xpress / AI model reads brain MRIs in seconds, hitting up to 97.5% accuracy
An AI-powered model developed at the University of Michigan can read a brain MRI and diagnose a person in seconds, a study suggests. The model detected neurological conditions with up to 97.5% accuracy and predicted how urgently ...
Phys.org / When Earth's magnetic field took its time flipping
Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are called geomagnetic reversals, ...
Phys.org / A student made cosmic dust in her lab—what she found could help us understand how life started on Earth
A Sydney Ph.D. student has recreated a tiny piece of the universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how the chemical building blocks of life may have formed ...
