Another bit of science fiction is coming to life as scientists develop a highly elastic and adhesive surgical glue similar to the one Ryan Gosling used to seal his wound in Blade Runner 2049.

Surgeons use sutures, staples, and wires (sometimes in combination with adhesive substances) to facilitate healing of external and internal wounds. These methods, however, are not optimal, especially for reconnecting contracting tissues like those of lungs, arteries and the heart.

Sutures are also not ideal for preventing the leaking of liquids from incisions. In addition, piercing tissues to place sutures can further damage the surrounding wound area and can increase the risk for infection.

For many of us, remembering faces from 30 years ago can be something of a challenge. But cells in our immune system can remember old foes just fine, and we’ve never really been sure exactly how they manage it.

A new study has filled in missing details on the steps our body takes to remember pathogens, finally revealing the steps our immune cells take to preserve a reference library of past battles.

Scientists from the University of California, Berkeley, used a hydrogen isotope to label white blood cells inside volunteers, and tracked a specially selected virus from infection to immunity in order to record significant steps in the immune process.
