Paper trail leads to heart valve discoveries

Paper is at the heart of an experimental device developed by Rice University bioengineers to study heart disease. They are using paper-based structures that mimic the layered nature of aortic valves, the tough, flexible tissues that keep blood flowing through the heart in one direction only. The devices allow the engineers […]

New ‘don’t eat me’ signal may provide basis for cancer therapies

Researchers at the Stanford University School of Medicine have discovered a new signal that cancers seem to use to evade detection and destruction by the immune system. The scientists have shown that blocking this signal in mice implanted with human cancers allows immune cells to attack the cancers. Blocking other “don’t eat […]
