New platform can help treat neurodegenerative diseases through regenerative medicine


New platform can help treat neurodegenerative diseases through regenerative medicine
Imagine if surgeons could transplant healthy neurons into patients living with neurodegenerative diseases or brain and spinal cord injuries. And imagine if they could grow these neurons in the laboratory from a patient s own cells using a synthetic, highly bioactive material that is suitable for 3D printing.
By discovering a new printable biomaterial that can mimic properties of brain tissue, Northwestern University researchers are now closer to developing a platform capable of treating these conditions using regenerative medicine.
A key ingredient to the discovery is the ability to control the self-assembly processes of molecules within the material, enabling the researchers to modify the structure and functions of the systems from the nanoscale to the scale of visible features. ....

Scientists have created a new soft robot activated by light and magnetism


Its weight consists of almost 90% water, this minuscule, centimeter-sized bot comes alive without the need for intricate hardware, hydraulics, or electrical current. Strangely, the source of its amazing animation is light and its attraction to an external rotating magnetic field according to a paper published Dec. 9 in the online journal Science Robotics.

Conventional robots are typically heavy machines with lots of hardware and electronics that are unable to interact safely with soft structures, including humans, explained Samuel I. Stupp, study co-author and director of the Center for Bio-Inspired Energy Science, a Northwestern-based Energy Frontier Research Center funded by the U.S. Department of Energy.   We have designed soft materials with molecular intelligence to enable them to behave like robots of any size and perform useful functions in tiny spaces, underwater or underground. ....
