Researchers from Rice University and Baylor College of Medicine (BCM) have broken one of the major roadblocks on the path to growing transplantable tissue in the lab: They've found a way to grow the blood vessels and capillaries needed to keep tissues alive.
"The inability to grow blood-vessel networks, or vasculature, ...

Researchers at Rice University unveiled a new method for dissolving half-millimeter-long carbon nanotubes in solution, a breakthrough that could pave the way to the development of highly conductive quantum nanowire. Nanotubes have the frustrating habit of bundling, making them less useful than when they're separated in a solution. Rice scientists led by ...

An assistant professor of bioengineering at Rice University (Houston, TX, USA), Tomasz Tkaczyk, is developing a field-of-view (FOV) endoscope for detecting cancer with low- and high-resolution imaging systems. Using reflectance imaging, the Bi-FOV endoscope works by analyzing the interaction of light with tissue to reveal ...
