Douglas Smith, a professor of neurosurgery at the University of Pennsylvania, explains how his new nerve stretching technique works to grow artificial nerve transplants.
Biomedical engineer Erin Lavik discusses her research developing nanoparticles that promotes blood clotting.
The winners of the American Society for Cell Biology's annual image contest reveal the beauty within cells.
This video shows a person using the University of Wisconsin Brain-Computer Interface system with tongue stimulation.
This movie shows the thin-film micro-ECoG device being pressed down on the surface of water in a petri dish. The ultraflexible nature of the implant means that it cannot exert enough force to break the surface tension of the water. And the properties of polymer used allow it to stick and grab on to the water’s surface. The same thing happens when it is placed on the hydrated surface of the brain, allowing the implant to float with the brain as it moves within the skull without losing contact with the cortical surface.
The emerging field of connectomics could help researchers decode the brain’s approach to information processing.
The technologies that are sure to better the industry.
Zhenan Bao, an associate professor of chemical engineering, and Christopher Bettinger, a postdoctoral fellow, show off the biodegradable electronics they make in their lab at Stanford University.
In the first part of this time-lapse video, an immune cell equipped with a tiny polymer backpack gambols across a microscope slide for some six hours before getting stuck. In the second part of the video, cells with backpacks full of magnetic nanoparticles are tugged toward a magnet, while cells without backpacks stay put.
Scientists build new materials using inspiration from complex biological forms.
