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 / Open-access software tool helps researchers spot fake journals
Research papers in peer-reviewed academic journals are at the heart of academic integrity. New ideas and discoveries are vetted and checked by experts in the field as the boundaries of scientific knowledge are pushed forward. ...
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 / How play and social connection may help some dogs understand words
Some dogs are seemingly more talented than others. So-called gifted word learners (GWL) are rare canines that can rapidly learn the names of toys, a skill that most dogs don't possess. To understand why this is so, researchers ...
Phys.org / Weight-loss drugs are creating an environmental disaster—a new water-based method aims to change that
The world is in the middle of a peptide drug revolution. These short chains of amino acids—the building blocks of proteins—sit at the heart of some of the most successful medicines ever created, from weight-loss injections ...
Phys.org / Global warming is speeding breakdown of major greenhouse gas, research shows
Scientists at the University of California, Irvine have discovered that climate change is causing nitrous oxide, a potent greenhouse gas and ozone-depleting substance, to break down in the atmosphere more quickly than previously ...
Phys.org / New model predicts the melting of free-floating ice in calm water
A pair of US researchers have developed a new model to tackle a deceptively simple problem: how a small block of ice melts while floating in calm water. Using an advanced experimental setup, Daisuke Noto and Hugo Ulloa at ...
Phys.org / Reproduction in space, an environment hostile to human biology
As commercial spaceflight draws ever closer and time spent in space continues to extend, the question of reproductive health beyond the bounds of planet Earth is no longer theoretical but now "urgently practical," according ...
Phys.org / A new class of strange one-dimensional particles
Physicists have long categorized every elementary particle in our three-dimensional universe as being either a boson or a fermion—the former category mostly capturing force carriers like photons, the latter including the ...
Phys.org / Supermassive black holes sit in 'eye of their own storms,' studies find
Gigantic black holes lurk at the center of virtually every galaxy, including ours, but we've lacked a precise picture of what impact they have on their surroundings. However, a University of Chicago-led group of scientists ...
Phys.org / Political division in the US surged from 2008 onward, study suggests
Divisions within the US population on social and political issues have increased by 64% since 1988, with almost all this coming after 2008, according to a study tracking polarization from the end of the Reagan era to the ...
Phys.org / One-of-a-kind 'plasma tunnel' recreates extreme conditions spacecraft face upon reentry
Picture a spacecraft returning to Earth after a long journey. The vehicle slams into the planet's atmosphere at roughly 17,000 miles per hour. A shockwave erupts. Molecules in the air are ripped apart, forming a plasma—a ...
