How did early cells keep themselves distinct while allowing for some amount of exchange? UChicago Pritzker School of Molecular Engineering/Peter Allen, Second Bay Studios

Rain may have helped form the first cells, kick‑starting life as we know it

The earliest cells likely didn’t have membranes to separate and protect their components and chemistry away from a harsh surrounding environment. But they may have made do with rain.

Separating molecules is a highly energy‑intensive but essential part of drug development, desalination and other industrial processes – improving membranes can help

Around half of US industrial energy use goes toward separating molecules in industrial processes. Developing materials that can withstand harsh industrial conditions can help increase efficiency.

Hemodialysis: New research could vastly improve this life‑sustaining treatment for kidney failure patients

Hemodialysis filters kidney patients’ blood through a machine. Improving the membranes that mimic kidney function could reduce complications and side-effects, with better treatment results.
