Phys.org / Topological solitons power a chip-scale frequency comb source
Caltech scientists have developed a new way to produce optical frequency combs—important tools in devices that keep time and measure distances very precisely—at the chip scale, an advance that should make it easier to ...
Phys.org / Self-cleaning fabric could eliminate the need for detergent
Detergents may begin their journey by cleaning our clothes, but they end up contaminating the environment, flowing into rivers, ponds, and oceans, where they severely disrupt aquatic animal life. Even after wastewater treatment, ...
Phys.org / Ancient sling bullet delivers a 2,100-year-old taunt: 'Learn your lesson!'
For millennia, sling bullets served as a hand-thrown projectile that could be used to fend off enemies. At Hippos, 70 sling bullets made of lead have been recovered over the course of fieldwork and excavation. However, while ...
Tech Xplore / Dust-resilient perovskite solar cells could cut manufacturing costs and expand green energy worldwide
Research appearing in Communications Materials has shown that perovskite solar cells (PSCs) are remarkably resilient to dust during production, challenging the industry belief that high-performance solar technology must be ...
Medical Xpress / Scientists call out health-harming corporations driving rise in chronic disease
Chronic diseases including cancer, diabetes, neurocognitive disorders and infertility are rising globally, with health-harming products such as fossil fuels, tobacco, ultra-processed foods, toxic chemicals, plastics and alcohol ...
Phys.org / If the Laschamps geomagnetic excursion happened today, aviation radiation exposure would be radically altered
Earth's magnetic field acts as a vital shield against radiation arriving from space, but it is not constant. A new international study has examined how a reduction of the magnetic field similar to the Laschamps excursion ...
Phys.org / Motivations behind violent extremism uncovered in new global study
New research from the University of St Andrews has revealed that human readiness for intergroup violence is not a single or unified mindset. Published in the Proceedings of the National Academy of Sciences, the new study, ...
Phys.org / A spinel crystal structure exhibits unusual, pressure-induced superconductivity
Superconductors are materials that conduct electricity with an electrical resistance of zero. Superconductivity is generally observed when materials are cooled down to extremely low temperatures. In some cases, however, like ...
Medical Xpress / Why do some viruses linger for life? A 900,000-person study maps viral loads
Some viruses that make us sick are cleared by the immune system within days, while others lurk in our bodies for a lifetime and reemerge later to cause new problems. How and why viral levels in the body change over time—and ...
Tech Xplore / Mach 1.5 tests reveal noise feedback loops from supersonic jets
Researchers from the FAMU-FSU College of Engineering and the Florida Center for Advanced Aero-Propulsion, or FCAAP, are helping to solve a safety challenge in military aviation: the extreme noise generated by supersonic jets ...
Phys.org / Red-tailed bumblebees found to be key hosts for dangerous bee virus
Wild bumblebees serve as key hosts for acute bee paralysis virus. While the virus appears to cause little harm to bumblebees, infection is usually fatal to honeybees. Until now, it was assumed that honeybees were the key ...
Phys.org / How the body senses cold has been a mystery—until now
When you reach into a bucket of ice, open your front door on a snowy day, or feel the tingle of menthol toothpaste, a protein in your nerve cells called TRPM8 springs into action, opening like a tiny gate to send a "cold" ...
