Published New method flips the script on topological physics
(via sciencedaily.com) Original source The branch of mathematics known as topology has become a cornerstone of modern physics thanks to the remarkable -- and above all reliable -- properties it can impart to a material or system. Unfortunately, identifying topological systems, or even designing new ones, is generally a tedious process that requires exactly matching the physical system to a mathematical model. Researchers have demonstrated a model-free method for identifying topology, enabling the discovery of new topological materials using a purely experimental approach.
Published What coffee with cream can teach us about quantum physics
(via sciencedaily.com) Original source A new advancement in theoretical physics could, one day, help engineers develop new kinds of computer chips that might store information for longer in very small objects.
Published When lab-trained AI meets the real world, 'mistakes can happen'
(via sciencedaily.com) Original source Human pathologists are extensively trained to detect when tissue samples from one patient mistakenly end up on another patient's microscope slides (a problem known as tissue contamination). But such contamination can easily confuse artificial intelligence (AI) models, which are often trained in pristine, simulated environments, reports a new study. Each of the four AI models in the study paid too much attention to the tissue contamination, which resulted in errors when diagnosing or detecting vessel damage, gestational age, lesions and prostate cancer, the study found.
Published New research guides mathematical model-building for gene regulatory networks
(via sciencedaily.com) Original source A newly published study provides guidance for building accurate mathematical models for gene regulatory networks.
Published AI harnesses tumor genetics to predict treatment response
(via sciencedaily.com) Original source Cancer resists treatment in a multitude of ways, but a new algorithm developed can decode them all simultaneously.
Published New AI makes better permafrost maps
(via sciencedaily.com) Original source New insights from artificial intelligence about permafrost coverage in the Arctic may soon give policy makers and land managers the high-resolution view they need to predict climate-change-driven threats to infrastructure such as oil pipelines, roads and national security facilities.
Published Researchers developing AI to make the internet more accessible
(via sciencedaily.com) Original source In an effort to make the internet more accessible for people with disabilities, researchers have begun developing an artificial intelligence agent that could complete complex tasks on any website using simple language commands.
Published New AI tool accurately detects COVID-19 from chest X-rays
(via sciencedaily.com) Original source Researchers have developed a groundbreaking artificial intelligence (AI) system that can rapidly detect COVID-19 from chest X-rays with more than 98 percent accuracy.
Published A new mathematical language for biological networks
(via sciencedaily.com) Original source Researchers are presenting a novel concept for the mathematical modeling of genetic interactions in biological systems. The team has successfully identified master regulators within the context of an entire genetic network. The research results provide a coherent theoretical framework for analyzing biological networks.
Published Using AI, researchers identify a new class of antibiotic candidates
(via sciencedaily.com) Original source Using artificial intelligence, researchers discovered a class of compounds that can kill methicillin-resistant Staphylococcus aureus (MRSA), a drug-resistant bacterium that causes more than 10,000 deaths in the U.S. each year.
Published Large language models validate misinformation
(via sciencedaily.com) Original source In a recent study, researchers systematically tested an early version of ChatGPT's understanding of statements in six categories: facts, conspiracies, controversies, misconceptions, stereotypes, and fiction.
Published Giving video games this Christmas? New research underlines need to be aware of loot box risks
(via sciencedaily.com) Original source At-risk individuals, such as those with known gaming and gambling problems, are more likely to engage with loot boxes than those without. The study is the result of one of the largest, most complex and robustly designed surveys yet conducted on loot boxes, and has prompted experts to reiterate the call for stricter enforcement around them.
Published Clinicians could be fooled by biased AI, despite explanations
(via sciencedaily.com) Original source A new study finds that clinicians were fooled by biased AI models, even with provided explanations for how the model generated its diagnosis.
Published AI's memory-forming mechanism found to be strikingly similar to that of the brain
(via sciencedaily.com) Original source An interdisciplinary team consisting of researchers has revealed a striking similarity between the memory processing of artificial intelligence (AI) models and the hippocampus of the human brain. This new finding provides a novel perspective on memory consolidation, which is a process that transforms short-term memories into long-term ones, in AI systems.
Published Artificial intelligence can predict events in people's lives
(via sciencedaily.com) Original source Artificial intelligence can analyze registry data on people's residence, education, income, health and working conditions and, with high accuracy, predict life events.
Published Computational model captures the elusive transition states of chemical reactions
(via sciencedaily.com) Original source Researchers developed a way to quickly calculate the transition state structure of a chemical reaction, using machine-learning models.
Published Deep neural networks show promise as models of human hearing
(via sciencedaily.com) Original source In the largest study yet of deep neural networks trained to perform auditory tasks, researchers found most of these models generate internal representations that share properties of representations seen in the human brain when people are listening to the same sounds.
Published Artificial intelligence systems excel at imitation, but not innovation
(via sciencedaily.com) Original source Artificial intelligence (AI) systems are often depicted as sentient agents poised to overshadow the human mind. But AI lacks the crucial human ability of innovation, researchers have found.
Published ChatGPT often won't defend its answers -- even when it is right
(via sciencedaily.com) Original source ChatGPT may do an impressive job at correctly answering complex questions, but a new study suggests it may be absurdly easy to convince the AI chatbot that it's in the wrong.
Published North Korea and beyond: AI-powered satellite analysis reveals the unseen economic landscape of underdeveloped nations?
(via sciencedaily.com) Original source A joint research team in computer science, economics, and geography has developed an artificial intelligence (AI) technology to measure grid-level economic development within six-square-kilometer regions. This AI technology is applicable in regions with limited statistical data (e.g., North Korea), supporting international efforts to propose policies for economic growth and poverty reduction in underdeveloped countries. The research team plans to make this technology freely available for use to contribute to the United Nations' Sustainable Development Goals (SDGs).
