Cobra venom kills by collapsing blood vessels, organ-on-a-chip shows

Scientists have created a miniature"blood-vessel-on-a-chip" to study how snake venom can cause fatal internal bleeding — and to help develop new antivenoms to stop it.

The team used exposed the new chip to venom milked from four species of snakes: Indian cobras , West African carpet vipers , many-banded kraits and Mozambique spitting cobras . The snakes belong to the most venomous families of snakes — the vipers and elapids.

While mice and other animals share aspects of humans' biology, the blood-vessel-on-a-chip incorporates actual cells from humans and can be controlled in the lab more easily and cheaply.
