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 ...
Phys.org / How reproductive injustice in early modern Europe could mirror that of today
"There was no such thing as reproductive freedom for poor women in early modern Catholic Europe," states a recent article in the Journal of Modern History. The work examines several facets of "reproductive unfreedom" in the ...
Phys.org / A dinosaur with spikes exhibiting unprecedented properties discovered in China
Documented for 200 years, the Iguanodontia group is expanding with the discovery of a brand-new species, the first known to bear spikes with properties never before observed in dinosaurs. Scientists from the CNRS1 and their ...
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 ...
Medical Xpress / Preclinical study successfully reverses loss of blood flow to brain, an early sign of Alzheimer's disease
Supriya Chakraborty might have been studying insects in a lab had it not been for an immunology college instructor in India who taught him about the superheroes inside him—immune cells that wage a battle against bacteria, ...
Phys.org / Did trees in the Dolomites anticipate a solar eclipse? Not quite, say researchers
Around 14 hours before a partial solar eclipse passed over the Dolomites in Northern Italy, a group of spruce trees showed a sudden, synchronized increase in electrical activity. Previous research by Alessandro Chiolerio ...
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. ...
Phys.org / A new comet was just discovered. Will it be visible in broad daylight?
A newly discovered comet has astronomers excited, with the potential to be a spectacular sight in early April. C/2026 A1 (MAPS) was spotted by a team of four amateur astronomers with a remotely operated telescope in the Atacama ...
Phys.org / Three-component catalyst boosts ammonia from nitrate electrolysis by more than 50%
A research team led by Dr. Dandan Gao from the Department of Chemistry at Johannes Gutenberg University Mainz (JGU) has developed a new method for the sustainable production of ammonia and formic acid. Ammonia is indispensable ...
Phys.org / Concert formats measurably change audience experience, classical music study finds
Orchestras and festival organizers continually develop and experiment with new concert formats for classical music. But do these formats actually have an impact on audiences? A research team led by the Max Planck Institute ...
