Detecting disease with a single molecule: Nanopore-based sensors could transform diagnostics
The sensor is a glass tube whose tip is melted into a sharp needle-like structure that is immersed in a liquid containing molecules. Credit: Kevin Freedman/ImageFX/UCR Scientists at the University of California, Riverside have developed a nanopore-based tool that can diagnose diseases much faster and more accurately than current tests by capturing signals from individual molecules. The molecules that scientists…

Universal barcodes enable fast small molecule synthesis
Commonalities outline a roadmap to rapid analysis. Credit: Nature (2024). DOI: 10.1038/s41586-024-08211-4 The development of molecules to study and treat diseases is increasingly burdened by the time and specificity required to analyze the vast amounts of data generated by synthesizing large collections of new molecules. It’s taking place. Scientists at St. Jude Children’s Research Hospital present a new solution to…

New molecule can mimic the effects of fasting and exercise
The diagram on the left shows the chemical structure of LaKe. The graph on the right shows how blood lactate and ketone body (BHB) concentrations change over time in rats ingesting LaKe (blue curve) or a control substance (black curve). Both lactate and BHB are found to be significantly increased in rats fed LaKe. Credit: Aarhus University/Thomas Poulsen It is…
