Collaboration between researchers at Emory University and Georgia Institute of Technology (Georgia Tech) resulted in the development of stem cells that can be directed by magnetic fields. Stem cells could soon be intravenous injected into the patient to treat heart diseases and vascular problems. By loading stem cells with superparamagnetic iron oxide nanoparticles (SPIOs), scientists… »

Sensorineural hearing loss is the most common form and it is caused by the loss of sensory hair cells in the cochlea. Unlike birds and fish, mammals do not regenerate these auditory hair cells, so we relied on hearing aids and cochlear implants to aid in these situations. Massachusetts Eye and Ear and Harvard Medical School… »

Harvard University researchers have developed a biocompatible sponge made out of a gel-based material that can be molded into any shape and compressed to a small fraction of its size. This ability allows it to be delivered via injection and restore its original shape and size while gradually releases its cargo. Since it is biocompatible… »
