Phys.org / Divers may think they protect reefs, but one unseen habit is taking a steady toll
Research at the University of Sydney has found that scuba-diving tourism—widely promoted as a sustainable way to experience coral reefs—is causing frequent and often hidden damage to fragile marine ecosystems.
Tech Xplore / New light-based switch could cut chip energy use and speed future AI photonics
Photonic devices are hardware systems that can process information using light instead of electricity. These systems could potentially perform computations faster than electronic devices, while also consuming less energy.
Phys.org / Ancient DNA rewrites the story of a historical Sámi burial
A new study by the University of Turku and partners provides fresh insights into an individual buried near Lake Kitka in Kuusamo, Finland, at the turn of the 17th century (c. 1600 CE). DNA and isotope analyses show that the ...
Phys.org / Reconstructed 1.5‑billion‑year‑old protein network reveals hundreds of hidden disease‑linked genes
A University of Texas at Austin-led team has reconstructed the most detailed map to date of the molecular machines that carried out the functions of life in an ancient ancestor that gave rise to all complex life on Earth, ...
Medical Xpress / Scientists validate a link between autoimmunity and long COVID
A Mount Sinai-led research team has demonstrated that autoimmunity, in which the body's immune system attacks its own tissues, is responsible for the often-debilitating and confounding symptoms of long COVID in a subset of ...
Medical Xpress / Eating fewer protein-rich foods may harm our physical function as we grow older
Researchers have found that consuming lower amounts of protein-rich foods may negatively affect physical functioning as people grow older, underscoring the vital function protein plays in preserving mobility and muscle strength ...
Phys.org / Human-linked foraging reshapes dolphin social networks in Florida over decades
Wild dolphins are known for their complex social lives, but new research shows those social networks can be influenced by human activity.
Phys.org / Gentoo penguins cope with climate change heat waves by breeding earlier
Over the past few decades, heat waves have become more common in several parts of the world as our planet warms. That's a huge problem for many animals, as it can lead to habitat loss and push their bodies to lethal thresholds. ...
Phys.org / MIZ-ing in action: How much of Antarctic sea ice is affected by waves?
Using old satellite radar techniques, scientists have developed a new way of measuring the true extent of an understudied and crucial region of the Antarctic sea-ice system for the first time. The Marginal Ice Zone (MIZ) ...
Phys.org / Deep beneath Utah, rare mantle earthquakes reshape seismic hazard questions
Nearly 50 years ago, a puzzling earthquake beneath northern Utah jolted scientists' understanding of how Earth works. Now, research from the University of Utah confirms that the mysterious event was real, and part of a rare ...
Phys.org / Ancient lake cores reveal unprecedented 2012 Rwenzori fire and ecological shift
For the past several years, Penn State geoscientist Sarah Ivory and her students have been among a team of scientists scaling the East African Rwenzori Mountains, collecting sediment core samples from lakes formed at the ...
Tech Xplore / Breaking the optical barrier: Terahertz tech could help enable quantum internet security
A new method to distribute cryptographic keys using terahertz waves could help enable secure communication in the quantum-powered internet of the future, researchers say. Engineers from the University of Glasgow are pioneering ...
