Phys.org / How to watch one of the year's best meteor showers, the Geminids
It's time for one of the strongest meteor showers of the year.
Phys.org / Turning everyday filter paper into a miniature microfluidic platform with DLP 3D printing
Scientists used a 3D-printing approach to pattern hydrophobic barriers inside hydrophilic filter paper. These barriers, designed in different geometries, guide liquids along precise paths and shape their flow behavior, demonstrating ...
Phys.org / Polarized light boosts accuracy of wearable health sensors for all skin tones
Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart rate, sleep, and oxygenation.
Phys.org / Pompeii offers insights into ancient Roman building technology
Concrete was the foundation of the ancient Roman empire. It enabled Rome's storied architectural revolution as well as the construction of buildings, bridges, and aqueducts, many of which are still used some 2,000 years after ...
Phys.org / Q&A: Why self-appraisals may not be best way to judge job performance
Companies often rely on annual employee reviews to determine who gets promoted, who gets a raise, and who are the best candidates for layoffs. But research has shown the process can be influenced by factors other than job ...
Tech Xplore / AI headphones automatically learn who you're talking to—and let you hear them better
Holding a conversation in a crowded room often leads to the frustrating "cocktail party problem," or the challenge of separating the voices of conversation partners from a hubbub. It's a mentally taxing situation that can ...
Phys.org / From light to logic: Ultrafast quantum switching in 2D materials
Scientists from the Indian Institute of Technology Bombay have found a way to use light to control and read tiny quantum states inside atom-thin materials. The simple technique could pave the way for computers that are dramatically ...
Tech Xplore / Driverless taxis are heading to the UK, but it's still not clear who to blame when something goes wrong
Driverless taxis are a bit like buses. You wait ages for one, and then a fleet arrives all at once. The US firms Waymo and Uber have both said their vehicles will be on the streets of London in 2026.
Phys.org / The Nancy Grace Roman Telescope is complete
If you feel a thrill every time we discover something new about the cosmos, then November 25th may have been a noteworthy day to you. That's the day that NASA completed assembly of the Nancy Grace Roman Telescope. The two ...
Medical Xpress / Rethinking long-term allergy treatments: Experimental vaccine protects against anaphylaxis in mice
Researchers led by the Institut Pasteur, Université Paris, have developed a vaccine that elicits anti-Immunoglobulin E antibodies in humanized mice, protects against Immunoglobulin E-mediated anaphylaxis, and shows no detectable ...
Medical Xpress / Reversing treatment resistance in prostate cancer: Study solves longstanding puzzle in tumor biology
Scientists at the Herbert Irving Comprehensive Cancer Center (HICCC) have discovered a key mechanism that makes prostate cancer cells resistant to the latest drugs used to treat them. Their findings, reported in the current ...
Medical Xpress / Mini brains, big questions: Science is racing ahead of ethics
In a little over ten years, organoid models—miniature, lab-grown clusters of cells that imitate real organs—have transformed how we study human development and disease while accelerating drug discovery. As a bonus, they've ...
