Changing topic bias in biomedical science maps by linking documents through alternative data sources: policy documents, patents, authors, Facebook, and Twitter
arXiv:2412.07550v4 Announce Type: replace Abstract: Traditional science maps visualize topics by clustering documents within a network, but they are inherently biased toward clustering certain topics over others. If these topics could be chosen, then the science maps could be tailored for different needs. In this paper, we explore the extent to which the topic bias of a science map can be changed by choosing different data sources to build the document network.
RNA 'cut-and-patch' tool repairs faulty messages without altering DNA
A research team from the School of Biomedical Sciences at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), has achieved a significant advance in biotechnology that could revolutionize treatment strategies for neurodegenerative diseases. The team has developed a novel tool called RNA Segment Editing (RSE), which functions like a "cut-and-patch" tool for RNA. This innovative approach allows scientists to precisely remove or replace faulty segments of genetic messages within...
Quantifying Evidence for Competing Biomedical Hypotheses using Large Language Models and Bayesian Analysis
Science fundamentally depends on the generation and testing of hypotheses, many of them controversial. An explosion in scientific literature has made evaluating hypotheses even within a domain a problem of scale, and risks slowing an already extensive consensus-building process. While this challenge has prompted interest in automated hypothesis evaluation tools, existing methods have not yet proven effective for comparing hypotheses.
A Novel Data Augmentation Strategy for Robust Deep Learning Classification of Biomedical Time-Series Data: Application to ECG and EEG Analysis
Announce Type: cross Abstract: The increasing need for accurate and unified analysis of diverse biological signals, such as ECG and EEG, is paramount for comprehensive patient assessment, especially in synchronous monitoring. Despite advances in multi-sensor fusion, a critical gap remains in developing unified architectures that effectively process and extract features from fundamentally different physiological signals. Another challenge is the inherent class imbalance in many biomedical...
Novel synthetic biomolecule degrades disease-related proteins
Novel synthetic biomolecule degrades disease-related proteins Lisa Lock Scientific Editor Robert Egan Associate Editor Northwestern Medicine scientists have developed a novel synthetic biomolecular condensate that can degrade intracellular disease-causing proteins, providing a framework for new therapeutic approaches for a wide range of diseases, as detailed in a recent study published in Nature Communications. Shana Kelley, Ph.D., the Neena B. Schwartz Professor of Chemistry, Biomedical...
Mid-Infrared Single-Photon Edge Enhanced Imaging based on Nonlinear Vortex Filtering
Announce Type: new Abstract: Edge enhanced imaging via the spiral phase contrast enables to reveal the phase or amplitude gradients of a target, which has been proved useful in feature recognition, machine vision, and object identification. A long quest is to extend the operation wavelength into the mid-infrared (MIR) region, as highly demanded in various fields including infrared sensing, astronomic observation, and biomedical diagnosis.
MMBU: A Massive Multi-modal Biomedical Understanding Benchmark to Probe the Perception Capabilities of Vision-Language Models
arXiv:2606.06696v1 Announce Type: new Abstract: Vision and language models (VLMs) hold immense promise to transform biomedical imaging workflows, from detecting lesions in chest X-rays to profiling cellular features in microscopy. Realizing this potential, however, requires robust and fine-grained visual perception. Models need to correctly interpret subtle features in images, and they must do so across diverse biomedical modalities, scales, and contexts.
New route to tailor-made diamond nanoparticles holds promise for quantum applications
New route to tailor-made diamond nanoparticles holds promise for quantum applications Stephanie Baum Scientific Editor Robert Egan Associate Editor Nanodiamonds are tiny diamond particles only a few nanometers in size. Because they are chemically highly stable and can host so-called color centers, optically active defects in the crystal lattice, they are considered promising materials for quantum technologies, sensing and biomedical research. Until now, however, it has been difficult to...
Diagnostic dilemma: Doctors couldn't explain why a boy was bleeding from his eyes, ears and nose
Diagnostic dilemma: Doctors couldn't explain why a boy was bleeding from his eyes, ears and nose A case of a boy who bled from his eyes eventually led doctors to a diagnosis that has been reported fewer than 50 times in the medical literature. The patient: An 11-year-old boy in India The symptoms: The boy's parents brought him to a hospital after he had several episodes of bleeding from his eyes, nose and ears. The episodes, which had occurred for about a month, seemed to start for no...
