Phys.org / Forget flatfooted lumbering T. rex. New research shows it walked on tiptoes
Powerful, fierce and the king of the Cretaceous world, Tyrannosaurus rex was the ultimate apex predator. But it was also surprisingly dainty on its feet, according to new research. Findings published in the journal Royal ...
Phys.org / Scientists synthesize stable N₄ radical anions under ambient conditions
A team of scientists from the University of Manchester and Oxford have synthesized stable nitrogen chain radical anions under ambient conditions. These molecules, which are normally too reactive to isolate and study under ...
Phys.org / Stale bread and bacteria could power a new era in green chemicals
Scientists have found a way to use common bacteria as tiny, green chemical factories to replace a process that currently relies on fossil fuels. In industrial hydrogenation, the hydrogen added to molecules to create products ...
Phys.org / Exceptionally preserved 551-million-year-old site suggests Avalon biota lasted longer
Researchers studying the soft-bodied Ediacaran biotas of the world generally accept that there are three distinct assemblages. The 575–560-million-year-old (Ma) Avalon Assemblage is best known from the Ediacaran of Newfoundland, ...
Phys.org / Missing methane: Countries may be underestimating wastewater greenhouse gas emissions
The amount of greenhouse gases produced by the wastewater sector may be higher than reports suggest. According to a paper published in the journal Nature Climate Change, countries are missing out on reporting a significant ...
Phys.org / PFAS exposure greater in wet pet food, study suggests
Ehime University investigators measured 34 per- and polyfluoroalkyl substances in 100 commercial dog and cat foods sold in Japan and detected PFAS across many products, with higher concentrations in fish-based foods and dry ...
Tech Xplore / AI is getting smarter, but not wiser: A new roadmap aims to fix that gap
A new study is the first to suggest realistic ways to integrate wisdom into artificial intelligence, to create AI systems that will be more robust, transparent, cooperative, and safe. Researchers from the University of Waterloo ...
Phys.org / A new, useful absorption limit for ultra-thin films
Ultrathin, conductive films such as those made of graphene are widely used in modern optoelectronic devices, but it has been thought that their efficacy is fundamentally limited: they can absorb at most half of the incident ...
Phys.org / How many bee species exist? New global count puts the total near 26,000
The world has far more bees than anyone realized. Scientists have, for the first time, estimated just how many species of bees are out there on a global scale, offering a clearer look at how these vital pollinators are distributed ...
Medical Xpress / Twenty years cancer-free: One man's story illustrates progress against follicular lymphoma
Twenty years. That's how long Robert Oman has been cancer-free, thanks to a clinical trial offered at the University of Rochester's Wilmot Cancer Institute. And he isn't alone: 70% of patients in the trial who had advanced-stage ...
Medical Xpress / HIV can develop resistance to blockbuster antiviral lenacapavir—but at a cost to the virus
Long-acting antiviral medications are transforming HIV prevention and care, requiring only minimalistic dosing. But as the use of lenacapavir expands, scientists are probing a critical question: If the virus evolves resistance, ...
Phys.org / High-performance cell atlas workflow driven by manifold fitting
Researchers from the National University of Singapore (NUS) have developed CellScope, a high-performance single-cell analysis framework that uses manifold fitting to analyze single-cell RNA sequencing (scRNA-seq) data. This ...
