Graphene-coated heart valves could sidestep harmful drugs

Every year thousands of people are fitted with artificial heart valves to replace their own malfunctioning valve. Many of these patients, however, have to remain on drugs that stop blood clotting on these artificial valves. ...

Shape-shifting molecular robots respond to DNA signals

A research group at Tohoku University and Japan Advanced Institute of Science and Technology has developed a molecular robot consisting of biomolecules, such as DNA and protein. The molecular robot was developed by integrating ...

Cellulose with Braille for cells

Artificial implants such as pacemakers often cause complications because the body identifies them as foreign objects. Researchers at ETH Zurich have now demonstrated a simple method to fabricate cellulose-sheaths for implants, ...

3-D printed tissues may keep athletes in action

Bioscientists are moving closer to 3-D-printed artificial tissues to help heal bone and cartilage typically damaged in sports-related injuries to knees, ankles and elbows.

Micro-device could pick up early signs of heart attack or stroke

In Australia each year, approximately 55,000 people suffer a heart attack, with a similar number suffering from stroke. Many are caused by blood clots that block the flow of blood to the heart, often in at-risk individuals ...
