Tufts University biologists using a frog model have demonstrated for the first time that it is possible to prevent tumors from forming and normalize tumors after they have formed by using light to control electrical signaling among cells. The work, which appears online in Oncotarget on March 16, is the first reported use of optogenetics to specifically manipulate bioelectrical signals to both prevent and cause regression of tumors induced by oncogenes.

Veeco Instruments announced today that Tufts University in Medford, Massachusetts has ordered two GENxplor™ R&D Molecular Beam Epitaxy (MBE) Systems for cutting-edge compound semiconductor research.
