Phys.org / Teachers tend to help the same kids repeatedly when using AI-powered tutoring tools
A new study finds teachers tend to provide assistance to similar subsets of students when using AI-powered educational tools, rather than touching base regularly with everyone in their classes. The findings could be used ...
Phys.org / Molecular 'leash' measures force-sensing protein activation at about 15 piconewtons
Researchers at the National University of Singapore (NUS) have built a molecular "leash" to pull directly on a force-sensing protein called Piezo1, and discovered it switches on at about 15 piconewtons, proving that it can ...
Medical Xpress / Treating tumors independently of oxygen: Photodynamic therapy uses hydrogen peroxide instead
Photodynamic treatment of cancer is based on administering an initially inactive substance that is only activated in the tumor via targeted light irradiation. It then generates reactive oxygen species that kill the cancer ...
Phys.org / How to eat an elephant: Fossil find in Tanzania shows oldest signs of butchering these giant mammals
Imagine a creature nearly twice the size of a modern African elephant, which can weigh up to 6,000 kg. This was Elephas (Paleoxodon) recki, a prehistoric titan that roamed the landscape of what is now Tanzania nearly two ...
Phys.org / Rich biodiversity found in Japan's deepest ocean trenches, including an unidentified 'mystery' species
A new study published in the Biodiversity Data Journal provides a profound look at life up to nearly 10 kilometers below the ocean's surface in the Japan, Ryukyu, and Izu-Ogasawara trenches. The research catalogs at least ...
Phys.org / Seizure of 2,000 ants at Nairobi airport highlights the hidden scale of insect trafficking
Last year Kenya Wildlife Service warned of a growing demand for garden ants in Europe and Asia, where some people view them as exotic pets. An attempt to smuggle over 2,000 garden ants out of the country's main international ...
Medical Xpress / Is sitting with your legs crossed actually bad for you?
Most of us were told off at some point for how we sat. "Don't cross your legs, you'll ruin your knees." "You'll get varicose veins." "Sit properly." "Sit up straight."
Phys.org / Bird flu spread could be impacted by where waterfowl like to live
The movement patterns of waterfowl, including ducks, swans and geese, may affect the spread of highly pathogenic avian influenza in bird populations, according to a new study from the University of Georgia. The findings are ...
Medical Xpress / Molecular map could unlock new treatments for heart and lung diseases
Scientists have created a new "molecular map" uncovering how an important human receptor involved in blood clotting and inflammation works—an advance that could help us design better drugs for conditions such as pulmonary ...
Phys.org / Ranks of Disparity: New approach fixes flaw in fairness algorithms
As organizations increasingly rely on algorithms to rank candidates for jobs, university spots, and financial services, a new method, named hyperFA*IR, offers a more principled approach when picking candidates based on a ...
Phys.org / Atmospheric dust gives plants nutrients through their leaves, study finds
Research in New Phytologist shows that plants can acquire nutrients not only from the soil but also from atmospheric dust that settles and dissolves on their leaves, releasing elements such as phosphorus and iron.
Phys.org / Quantum computing without interruptions
Mid-circuit measurements are one of the biggest practical hurdles in quantum error correction on encoded qubits. Researchers in Innsbruck and Aachen have now proposed and experimentally demonstrated that a universal fault-tolerant ...
