Extracellular matrix is the material that gives tissues their strength and stretch. It’s been hard to make well in the lab, but a Brown University team reports new success. The key was creating a culture environment that guided cells to make ECM themselves.
Four undergraduate biomedical engineers travelled to the annual meeting of the national Biomedical Engineering Society in Tampa, Florida October 7th-10th. At the conference, attendees presented research done at Brown to a national audience of academic professionals.
The burgeoning field of optogenetics makes it possible for scientists to control brain activity using pulses of light. Now, Brown University researchers have developed an optoelectronic device which opens the possibility of bidirectional communication with the brain — stimulating neural microcircuits while while monitoring changes in neural activity.
Brown University researchers have developed a method for detecting single nucleotide mutations directly in the RNA of HIV, including mutations that make it resistant to some drugs. In lab tests, the single-step system performed more quickly and with better sensitivity than standard technologies.
