SFMFNet: Spatial‐Frequency Multiscale Fusion Network for Left Ventricle Segmentation in Echocardiography

07/10/2026 - Automatic left ventricular segmentation in echocardiography is critical for cardiac function assessment but remains challenging due to limited crossdomain feature interaction. This paper proposes...

Learning fly pose from vision-language annotations

06/10/2026 - Animal pose estimation typically requires manual annotation of body parts to train neural networks for each new recording system or environmental condition. Here we use a general-purpose...

Shoes may change the structure of our ankle bones

06/10/2026 - Wearing shoes seems to affect the volume of a spongy network within a bone in our ankles, which could affect the validity of previous research into the evolution of walking

A versatile and stable reporter platform for human rhinovirus and other enteroviruses

05/10/2026 - Human rhinovirus (HRV), a major cause of upper respiratory infections, has increasingly been associated with lower respiratory tract disease. Although tools to investigate HRV pathogenesis are...

An Expanded Lpt Pathway Couples Surface Lipoprotein Export to Outer Membrane Vesicle Biogenesis in Bacteroides

05/10/2026 - The ecological dominance of Bacteroidota in the human gut microbiota derives from their exceptional capacity to metabolize diverse dietary and host-derived glycans. This ability relies on...

Killer meiotic driver prevents chromosome loss and enhances fitness in a fungal pathogen

05/10/2026 - Fungal pathogens often carry dispensable chromosomes (DCs) that confer a selective advantage in adverse environments or during host infection but can be spontaneously lost under non-selective...

Can we harness the brain’s deep-cleaning system to prevent Alzheimer’s?

05/10/2026 - The glymphatic system is the brain's recently discovered network for flushing out toxins. Now, we're uncovering surprising ways to boost it to protect brain health
