Discovery may enable the development of new therapies to kill aggressive cancer cells
The idea
Vanderbilt faculty and researchers are looking for the Achilles heel of the cancer cells that survive initial chemotherapy. Michael King, chair of the Department of Biomedical Engineering, and Joshua D. Greenlee, graduate research fellow in biomedical engineering, are investigating whether a naturally occurring protein made in immune cells, called TRAIL, is effective in killing colon cancer cells.
This knowledge may enable the development of new therapies that make aggressive cancer cells easier to kill off before they spread to other parts of the body.
The researchers found that TRAIL is more effective in killing these drug resistant colon cancer cells.
Research shows how neurons learn to pick the most energy-efficient perturbations
Brains have evolved to do more with less. Take a tiny insect brain, which has less than a million neurons but shows a diversity of behaviors and is more energy- efficient than current AI systems. These tiny brains serve as models for computing systems that are becoming more sophisticated as billions of silicon neurons can be implemented on hardware.
The secret to achieving energy-efficiency lies in the silicon neurons ability to learn to communicate and form networks, as shown by new research from the lab of Shantanu Chakrabartty, the Clifford W. Murphy Professor in the Preston M. Green Department of Electrical & Systems Engineering at Washington University in St. Louis McKelvey School of Engineering.
