A University of California San Diego research team has found a better way to understand and stabilize hydroxyapatite, the calcium phosphate mineral that makes up much of our teeth and bones. By adding tiny amounts of europium, a rare-earth element that mimics calcium, the team discovered a way to make the material potentially more useful for medical imaging.
Researchers from the University of Plymouth have led the production of a new report highlighting the impact of climate change on marine plankton and pelagic habitats in U.K. waters. Published by the Marine Climate Change Impacts Partnership (MCCIP), the report discusses the latest evidence showing major large-scale shifts already happening in plankton communities.
The formation and evolution of individual stars in a galaxy shape the evolution of the galaxy itself. Stars and stellar remnants make up the vast majority of a galaxy's mass, so it's not surprising that the stellar population affects the evolution of galaxies. In the Milky Way's disk and bulge, stars and dead stars make up about 85% of the baryonic mass.
Graphite, the carbon core of a humble No. 2 pencil, is also an essential component in technologies such as batteries, smartphones, laptops and industrial power equipment. Today, nearly all of this critical mineral must be mined and processed and, in the United States, imported.
As artificial intelligence becomes part of how people work, learn and solve problems, a new University of Phoenix survey conducted by The Harris Poll finds that recent working learners see meaningful opportunities for AI to support accessibility.
Cislunar space has become the focal point of considerable interest and strategic planning because of the many proposed missions to send crews to the moon in the next decade. These include NASA's Artemis program, China and Russia's International Lunar Research Station (ILRS), the European Space Agency's Argonaut program and others. The long-term goals of these programs include creating infrastructure between Earth and the moon that will facilitate continued exploration and even development.
An international team of researchers from École Polytechnique, Collège de France and Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has achieved a world first: the experimental realization of an all-optical photonic time crystal (PTC), a material whose optical properties can be strongly and periodically modulated over ultrafast timescales.
Researchers at Reichman University have developed a biological method for protecting marine infrastructure from corrosion caused by prolonged exposure to seawater. The study, published in Cell Reports Physical Science, presents an environmentally friendly alternative to the chemical corrosion inhibitors currently used to protect metals—materials that can be both polluting and costly.
There's a nice kind of irony buried in this story: One of the most sensitive instruments ever built, capable of measuring distortions smaller than the width of a proton, has been quietly held back by something as mundane as heat. And the fix, it turns out, is not some exotic new sensor but a thermal camera you could genuinely buy off the shelf.
Two of the world's most fire-prone regions have followed strikingly different wildfire trajectories despite both experiencing a warming climate. Burned forest area has surged across the U.S. Southwest, while eastern Australia has not seen the same increase.
