Tech Xplore / Researchers reveal bias in a widely used measure of algorithm performance
When scientists test algorithms that sort or classify data, they often turn to a trusted tool called Normalized Mutual Information (or NMI) to measure how well an algorithm's output matches reality. But according to new research, ...
Tech Xplore / Harry Potter-style 'moving invisibility cloak' technology developed
What do Harry Potter's invisibility cloak and stealth fighter jets that evade radar have in common? They both make objects invisible despite their physical presence. Building upon this concept, a research team has taken it ...
Phys.org / Dark matter search narrows as detector sets new limits and spots solar neutrinos
Australian researchers have played a central role in a landmark result from the LUX-ZEPLIN (LZ) experiment in South Dakota—the world's most sensitive dark matter detector. Today, scientists working on the experiment report ...
Medical Xpress / Harmless Klebsiella strain shows powerful protection against gut infections in inflammatory bowel disease model
A team of researchers led by Karina Xavier has uncovered a promising new live biotherapeutic agent that may redefine how the medical field approaches microbiota-based therapies.
Tech Xplore / How AI helps solve problems it doesn't even understand
Researchers at TU Wien have discovered an unexpected connection between two very different areas of artificial intelligence: Large Language Models (LLMs) can help solve logical problems—without actually "understanding" ...
Phys.org / People tend to overestimate others' emotions, but this may boost empathy
According to a new study led by Prof. Anat Perry and her Ph.D. student, Shir Genzer, of the Hebrew University of Jerusalem, together with Prof. Noga Cohen from the University of Haifa, chances are you're overestimating just ...
Phys.org / From cages to fields: Lab mice lose their anxiety after a week outdoors
When postdoctoral researcher Matthew Zipple releases lab mice into a large, enclosed field just off Cornell's campus, something remarkable happens.
Medical Xpress / 'Super flu' variant is circulating and raising concern: Here's what to know about it
A new version of the common flu is spreading globally, and health officials are monitoring this evolving strain of influenza A(H3N3) Subclade K, which has been increasingly detected worldwide.
Phys.org / Fort Lauderdale wants to help residents build 'living' seawalls
The City of Fort Lauderdale may soon make it easier for waterfront properties to install living seawalls—innovative underwater shoreline structures that mimic natural habitats, improve water quality and give marine life ...
Phys.org / Embrace chaos to get lifelike movement from synthetic materials, researchers say
When people think of high-powered machines, they'd likely think of muscle cars before their own muscles. But muscles and other living tissues can do energetic things very quickly—they twitch, snap and beat—which is how ...
Phys.org / The dinosaurs that forgot how to fly
A new study led by a researcher from the School of Zoology and the Steinhardt Museum of Natural History at Tel Aviv University examined dinosaur fossils preserved with their feathers and found that these dinosaurs had lost ...
Medical Xpress / First vaccine shows promise in protecting from deadly melioidosis infection
Melioidosis is a little-known tropical disease now seen as an emerging global public health threat. The disease is caused by bacteria that live in soil and groundwater, and no vaccine exists to prevent infection, which can ...
