Now, a $73 million DARPA effort aims to create shelf-stable versions of plasma, platelets, and red blood cells. The idea is to develop dried blood products that can be stored for long periods and deployed quickly on the battlefield.
The project aims to have bags of dried blood products deployed in the field by 2029. But getting it all done will be tough, and researchers still have major questions about the safety and effectiveness of synthetic alternatives.
Discover how the military hopes to make blood last longer.

10 Climate Tech Companies to Watch: WeLion New Energy and its semi-solid-state batteries
WeLion New Energy is one of MIT Technology Review’s10 Climate Tech Companies to Watch 2026, available exclusively to subscribers.
WeLion New Energy is on a quest to make safer, better batteries. The Chinese company’s liquid-solid hybrid cells aim to pack more power into electric cars, boats and drones, potentially improving safety and offering greater energy density than lithium-ion batteries.
In 2023, WeLion released a battery pack with EV-maker Nio that offered a range of over 1,000 kilometers. Now, the company is developing batteries with even higher energy density. But scaling up production and competing on cost remain major challenges.
