Phys.org / Portable sensor detects PFAS in water on-site, cutting need for costly lab tests
A new study has unveiled a new method to cost-effectively and practically test for "forever chemicals" in water, potentially revolutionizing environmental PFAS monitoring. Led by Griffith University, the novel PFAS detection ...
Phys.org / A new kind of CRISPR could treat viral infection and cancer by shredding sick cells' DNA
A new kind of CRISPR that destroys cells rather than gene editing them has shown potential for killing sick cells while leaving healthy cells untouched. The technology has largely been tested in cells in a dish, but if it ...
Phys.org / AI matches human teachers: Brief pre-lecture chat boosts students' brain synchrony and learning outcomes
Millions of students worldwide have long relied on self-paced learning through pre-recorded video lectures, a model that forms the backbone of massive open online courses (MOOCs) and large-scale online education. Since the ...
Phys.org / Landsat 9 captures Russia's restless Shiveluch volcano mid-eruption
Near-constant activity continues on the volcano in Russia. Shivelyuch (also called Shiveluch), the most northerly active volcano on the Kamchatka Peninsula, is one of the most active volcanoes in the world. On a near-daily ...
Phys.org / Online echo chambers can arise even without algorithmic nudges or seeking like-minded people
A new study of online communities suggests that their interaction dynamics can amplify small, local imbalances in opinions, rapidly turning initially mixed-opinion communities into highly-polarized ones—even without the algorithms ...
Phys.org / Fewer insects, fewer nutritious crops: Pollinator decline puts human health at risk
Biodiversity loss is directly threatening human health and welfare, according to new research led by the University of Bristol. The study, published in Nature reveals, for the first time, how the decline of insect pollinators ...
Phys.org / Bacterial protein map could open new path against drug-resistant infections
La Trobe scientists have made a pivotal discovery in the fight against dangerous drug-resistant bacteria, as the University launches a major research initiative focused on new ways to target antimicrobial resistance (AMR). ...
Phys.org / 'Not just hot water': Marine heat waves can create toxic relationship between seagrasses and microbes
Heat stress from marine heat waves can create a toxic relationship between seagrasses and a hidden ecosystem of bacteria, transforming a previously beneficial co-existence between marine plants and microbes into a harmful ...
Phys.org / Federal grant terminations disproportionately impact minority scientists, study finds
Researchers from University of California San Diego Herbert Wertheim School of Public Health and Human Longevity Science have found that recent federal grant terminations targeting research on health equity and gender identity ...
Phys.org / Deforestation may push Amazon degradation threshold below 2°C warming
Around two-thirds of the Amazon rainforest could shift into degraded forest or savanna-like ecosystems at 1.5–1.9°C of global warming if deforestation increases to roughly 22–28% of the Amazon, according to a new study from ...
Phys.org / The lost koala: New fossil species was hiding in plain sight for 100 years
In 2024, the Western Australian Museum received a donation. It was a koala skull collected from Moondyne Cave in Margaret River by Lindsay Hatcher, an avid caver. There was something a bit odd about this skull, and we were ...
Phys.org / A persistent quantum computing error finally explained
Scientists have discovered the cause of a persistent glitch that continues to disrupt superconducting quantum computers, even when they have built-in defenses. For all their advanced hardware, superconducting quantum computers ...
