A dynamic duo of cells identified in lung blood vessels
Scientists have identified two subtypes of lung blood vessel cells. One subtype expresses more genes involved in inflammation and the regulation of the immune response; the other expresses more genes involved in cell regeneration and proliferation. The findings could lead to better treatments for lung infections.

Robot Uses Artificial Intelligence and Imaging to Draw Blood
Rutgers engineers have created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs. Their research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on some complex medical tasks.
