Repair, Regrow, Regenerate - Scientists and engineers unlock the body’s healing powers

Northwestern researchers, including Samuel StuppGuillermo Ameer and John Kessler, are on the cusp of some superhuman breakthroughs, pushing the body’s boundaries through advances in regenerative medicine and engineering, with the goal of bringing healing and hope to countless people.

Severe spinal cord injuries repaired with 'dancing molecules'

Northwestern University researchers have developed a new injectable therapy that harnesses “dancing molecules” to reverse paralysis and repair tissue after severe spinal cord injuries. In a new study, researchers administered a single injection to tissues surrounding the spinal cords of paralyzed mice. Just four weeks later, the animals regained the ability to walk.

Photosynthesis-inspired process makes commodity chemicals

Northwestern University chemists have taken inspiration from plants to revolutionize the way an important industrial chemical is made. In a first for the field, the Northwestern team used light and water to convert acetylene into ethylene, a widely used, highly valuable chemical that is a key ingredient in plastics.

Northwestern, MIT researchers develop novel materials for energy and sensing

A team of researchers from Northwestern University and the Massachusetts Institute of Technology (MIT) has demonstrated the ability to fine-tune the electronic properties of hybrid perovskite materials, which have drawn enormous interest as potential next-generation optoelectronic materials for devices such as solar cells and light sources.

Mature ‘lab grown’ neurons hold promise for neurodegenerative disease

Northwestern University-led researchers have created the first highly mature neurons from human induced pluripotent stem cells (iPSCs), a feat that opens new opportunities for medical research and potential transplantation therapies for neurodegenerative diseases and traumatic injuries.

Aquatic robot inspired by sea creatures walks, rolls, transports cargo

Northwestern researchers have developed a first-of-its-kind soft, aquatic robot that is powered by light and rotating magnetic fields. These life-like robotic materials could someday be used as “smart” microscopic systems for production of fuels and drugs, environmental cleanup or transformative medical procedures.

A new wave of regenerative medicine born in movies

Materials science pioneer Samuel Stupp believes the future of regenerative medicine may be here sooner than we think. Concepts born in movies — operating suites equipped with 3D printers, lab-grown human tissue and implanted neurons — are now finding origins in Northwestern laboratories.

Synthetic materials mimic living creatures

Northwestern University researchers from the Center for Bio-Inspired Energy Science (CBES) have developed a family of soft materials that imitates living creatures. When hit with light, the film-thin materials come alive — bending, rotating and even crawling on surfaces.
