New grasp of key COVID-19 protein may lead to a live-attenuated vaccine effective against more variants for longer

Researchers have identified a key protein in SARS-CoV-2 that, when targeted, elicits a robust immune response. A live-attenuated vaccine based on this protein shows promise in preventing disease and offering long-lasting immunity. The approach could target areas of the genome less likely to change with variants.

Two studies demonstrate the benefits and limitations of artificial intelligence in colonoscopy

Two studies demonstrate that artificial intelligence in colonoscopy can increase adenoma detection rates and reduce miss rates, but also lead to increased removal of non-neoplastic polyps. The findings suggest the need for additional research on more defined detection parameters before AI can be integrated into routine clinical care.

NIH-funded study supports use of ECMO for critically ill patients with obesity

A National Institutes of Health-supported study suggests that adults with obesity may benefit from extracorporeal membrane oxygenation (ECMO) when in intensive care for respiratory failure. The study found lower mortality rates among patients with obesity who received ECMO compared to those without, contradicting previous concerns.

Rare disease shares mechanism with cystic fibrosis

Researchers discovered that a rare disease called cystinosis shares the same cellular mechanism as cystic fibrosis, involving the lysosome's recycling center. The study found that a specific protein degradation pathway was responsible for the disease's effects, and a small chemical chaperone could help stabilize the protein.

Researchers at UC Irvine issue a warning that GLP-1RA’s may be dangerous for children

Researchers at UC Irvine issue a warning that GLP-1RA's may be dangerous for children due to the risk of nutrient imbalance and abuse. The team notes that children need energy and sufficient calories for growth and development, and any change in their diet and exercise balance can have long-term health consequences.

Stevens researchers take aim at weather forecasters’ biggest blindspot

Researchers at Stevens Institute of Technology have developed more accurate nowcasting algorithms to predict short-term weather forecasts. The study found that probabilistic models are highly accurate in predicting both long- and short-term rainfall events, while deterministic models are better suited for extremely short-term projections.
