A team of scientists from Harvard Medical School and Duke University has created a new kind of tissue that can change heart activity using only light—no wires, no surgery, no harm. This groundbreaking ...

Heart cockles (Corculum cardissa) are bivalve molluscs a bit like clams that have a symbiotic relationship with photosynthetic algae that live inside them. The algae have a safe home, get light to ...

These congenital heart defects affect the organ's lower ... thin tube with a light-emitting tip. To activate the light-sensitive hydrogel inside the shunt, they intend for surgeons to insert ...

For the current study, the researchers used UT’s e-tattoo design to develop a device that could operate inside the ... who used light to monitor and control heart rhythm (optocardiography ...

Stanford University and Duke University has found that heart cockles have windows in their shells to allow in light needed by the algae that live inside the shells. Heart cockles are bivalve ...

Not only are the devices bulky and inflexible; the shocks they deliver also stimulate pain receptors in the heart. To improve on this design, Gutruf’s team explored an approach based on optogenetic ...
