Bioengineers at Boston’s Mass General Hospital have developed a fully automated device named SpinEx that is capable of isolating and analyzing tiny particles in the blood known as extracellular vesicles, or EVs. These vesicles are released by tumor cells and carry molecular signals that reveal whether cancer is present and pinpoint the type and the quantity of that cancer Current extracellular vesicle analysis methods are slow, manual, and limited to measuring one marker at a time. SpinEx, in contrast, speeds the process by combining the multiple steps of plasma separation, EV enrichment, and protein labeling of a minuscule 150 microliters of blood onto a single spinning disc that completes the process automatically. Two samples can be run simultaneously. The resultant unique EV protein “fingerprints” accurately distinguish cancer from non-cancer samples and successfully identify five different cancer types. After further clinical testing, this SpinEx technology will support earlier cancer detection, improved tumor classification, and ongoing monitoring following therapy all from a simple blood draw. https://medicalxpress.com/news/2026-01-lab-disc-device-paves-automated.html https://www.nature.com/articles/s41551-025-01601-7 https://wefluidics.com/sys-nd/1349.html #cancer #diagnosis #ev #vesicles #oncology".
NASA finds Titan's lakes may be creating vesicles with primitive cell walls

Saturn’s moon Titan may be more alive with possibilities than we thought. New NASA research suggests that in Titan’s freezing methane and ethane lakes, simple molecules could naturally arrange themselves into vesicles—tiny bubble-like structures that mimic the first steps toward life. These compartments, born from splashing droplets and complex chemistry in Titan’s atmosphere, could act like primitive cell walls.
NASA Research Shows Path Toward Protocells on Titan
Cell-like compartments called vesicles could form naturally in the lakes of Saturn’s moon, based on our current knowledge of the moon’s atmosphere and chemistry.

A coordinated recruitment of actin and myosin at large vesicles allows for the "exocytosis by vesicle crumpling" in Drosophila larval salivary glands.
Inès Jmel Boyer covers a preprint from Kumari Kamalesh & team which describes a mechanism that requires precise spatiotemporal control of actomyosin contractility.
