by Kate McAlpine, University of Michigan The new computer model, NeCLAS, predicts that a nanoparticle, shown as a set of yellow balls attached by netting, fits neatly around a very specific protrusion on a protein, marked in blue. The binding site is confirmed by experiments. These kinds of nanoparticles, called molecular tweezers, can be used to...
By Chloe Xiang May 30, 2023, 2:42 pm The National Eating Disorder Association (NEDA) has taken its chatbot called Tessa offline, two days before it was set to replace human associates who ran the organization’s hotline. After NEDA workers decided to unionize in early May, executives announced that on June 1, it would be ending the...
Maya Yang Thu 25 May 2023 15.54 EDT Scientists using artificial intelligence have discovered a new antibiotic that can kill a deadly superbug. According to a new study published on Thursday in the science journal Nature Chemical Biology, a group of scientists from McMaster University and the Massachusetts Institute of Technology have discovered a new antibiotic that...

by European Stroke Organization Conference Credit: CC0 Public Domain A team of researchers from Denmark has developed a new artificial intelligence (AI) framework to address the number of strokes that go unrecognized by human emergency call handlers. The framework outperformed emergency call handlers in recognizing stroke for both sexes and across all age groups studied, indicating its...
by Johns Hopkins University School of Medicine Pilot 119 melanin binding peptide microarray screening with machine learning analysis. a Schematic illustration of the first peptide microarray. Peptides were anchored to a microarray, and melanin nanoparticles (mNPs) with surface biotinylation (b-mNPs) were flowed over to characterize binding events. The fluorescence intensity of the biotin was detected using DyLight 680-conjugated...
by Texas Children’s Hospital The top 98 EAML genes are connected to GWAS genes, dysregulated in AD patients, and capable of separating AD and healthy control samples. Credit: Nature Communications (2023). DOI: 10.1038/s41467-023-38374-z Alzheimer’s disease (AD) is a complex neurodegenerative illness with genetic and environmental origins. Females experience faster cognitive decline and cerebral atrophy than males, while males...
by University of Illinois at Chicago Credit: University of Illinois at Chicago With scarce clinical resources unable to keep pace with elevated rates of mental illness, technological solutions could help decrease waitlists and disparities in access to therapy. Recent advances in artificial intelligence have fueled interest in the use of chatbots and virtual assistants for mental...
New AI tools may aid the early diagnosis of Parkinson’s disease. Design by MNT; Photography by EDUARD MUZHEVSKYI/SCIENCE PHOTO LIBRARY/Getty Images Researchers developed an AI tool to predict Parkinson’s disease from blood samples. The tool can predict Parkinson’s 15 years before symptom onset with 96% accuracy. The underlying technology could possibly be adapted for diagnosing other conditions. Parkinson’s...

Credit: Vienna University of Technology In the future, artificial intelligence will play an important role in medicine. In diagnostics, successful tests have already been performed: for example, the computer can learn to categorize images with...
