Image shows a blurry, tube-like structure in fluorescent red and green, against a black background.

Scientists have created a miniature ‘blood vessel-on-a-chip’ to study how snake venom can cause deadly internal bleeding – and to help develop new antivenoms to stop it. The new 3D model contains cells that line human blood vessels, known as endothelial cellsjust like the extracellular matrix, or physical framework that supports these cells. The device … Read more
