Droplet trains reveal how nature navigates blood traffic

Scientists report that they discovered spontaneous oscillations in microfluidic droplet networks. The scientists have successfully modeled network channels similar to our blood capillaries in the simplest way containing one or two loops. They also suggest that collision between blood cells and irregularity of thickness can dampen oscillations in the biological networks. This study can help us understand the emergence and corresponding behavior of the oscillations of blood flow in the microvascular networks.
