Tech Xplore / Grok created three million sexualized images, research says
Elon Musk's AI chatbot Grok generated an estimated three million sexualized images of women and children in a matter of days, researchers said Thursday, revealing the scale of the explicit content that sparked a global outcry.
Tech Xplore / Physicists predict significant growth for cadmium telluride photovoltaics
A solar energy generation technology once considered limited in its potential is poised for significant growth in the United States.
Phys.org / Cellulose-based composite sheet exhibits simultaneous adsorption and shielding of radioactive elements
Researchers at University of Tsukuba have developed a cellulose-based composite sheet that integrates paper pulp with starch, polyaniline (a conductive polymer), Prussian blue (a coordination compound), and alginic acid (a ...
Tech Xplore / Unlocking vast lithium stores: Faster, cleaner method extracts critical mineral from low-grade brines
Demand for lithium is skyrocketing as factories across the world churn out electric vehicles and the massive batteries that make wind turbines and solar panels reliable sources of energy. Unfortunately, current methods for ...
Phys.org / Climate adaptation may ease migration pressures in Africa
Africa confronts escalating internal migration and displacement crises fueled by intensifying climate hazards—particularly prolonged droughts—and persistent armed conflicts, which compound vulnerabilities across the continent.
Phys.org / How China can meet its rapidly growing cooling demand without heating the planet
China's rising demand for cooling doesn't have to drive rising temperatures. A recent study shows how rapid shifts to cleaner refrigerants and high-efficiency technologies could cut cooling-related climate impacts to near ...
Phys.org / Ultrafast light switches use atomically thin semiconductors for rapid optical control
A nanostructure made of silver and an atomically thin semiconductor layer can be turned into an ultrafast switching mirror device that may function as an optical transistor—with a switching speed around 10,000 times faster ...
Phys.org / Rye pollen's cancer-fighting structure revealed for first time
Nearly three decades ago, scientists found that a pair of molecules in rye pollen exhibited an unusual ability to slow tumor growth in animal models of cancer. But progress stalled for one seemingly simple reason: No one ...
Phys.org / Chiral phonons create orbital current via their own magnetism
In a new study, an international group of researchers has found that chiral phonons can create orbital current without needing magnetic elements—in part because chiral phonons have their own magnetic moments. Additionally, ...
Phys.org / Sweetening the deal for sustainability, while removing carbon dioxide
Here's a novel pathway to a more sustainable planet: carbo-loading for the public good. In a new study published in Nature Synthesis, chemists at Yale and the University of California-Berkeley have developed a two-step process ...
Phys.org / AI-induced cultural stagnation is no longer speculation. It's already happening
Generative AI was trained on centuries of art and writing produced by humans.
Phys.org / How a potential antibiotics ban could affect apple growers
Antibiotic resistance in human and animal health is at the forefront of public debate, but it's a less well-known issue in plant agriculture. However, antibiotics are important tools in fruit production, and their efficacy ...
