Detecting Eye Cancer with Your Smartphone
Early detection is the key to saving the eyesight and lives of patients with Retinoblastoma. Flash photography is a simple and easy way to detect this life-threatening eye cancer. The tumor can develop in young children from birth and often reflects back as a white pupil.
What is Neuromorphic Computing? Dr. Todd Hylton, Brain Corporation, spoke at the second IEEE Rebooting Computing Summit to share his insights and experiences. He stresses that building a computer from components that act as neurons is not the same thing as building a brain. Designing a computer with the functionality of a brain will be much more difficult.
Future of Surgical Robots
Dr Mohr spoke at Wired Health on the future of surgical robots. Though surgical robots have become prevalent in many hospitals and countries by making surgeries less invasive, they have not revolutionized surgeries inside the patients. The next phase is to look at surgical robots as a platform for integrating other technologies that can impact a patient outcome, such as enabling early detection of diseases, providing decision support during surgeries, and allowing surgeons to work at a different scale.
48 Hour ‘Hack-a-thon’ on Ebola

Researchers at Iowa State University, in Ames, Iowa, have received a grant to develop software libraries to support DNA data analysis on High Performance Computers (HPCs).
Path Found to a Combined MRI and CT Scanner
Researchers at Rensselaer Polytechnic Institute, in Troy, NY, are developing a combined scanning technology, using simultaneous MRI and CT scans, which they believe could benefit research and personalized medicine, for instance letting physicians get a better view of biological processes in action. But would the cost be prohibitive?
Electronic Implants That Disappear
Implants that dissolve in the body after they've done their work could solve biocompatibility problem.
Researchers at the University of Illinois at Urbana-Champaign and Tufts University say they have invented functional electronic implants that can dissolve after programmable time periods. To demonstrate the system, which could aid in healing during the first few crucial days after an operation, they implanted one in a rat. It created a temporary temperature increase to sterilize a wound, and then it dissolved after 15 days. Follow the link to the article on the IEEE Spectrum.

The Wyss Institute for Biologically Inspired Engineering at Harvard University today announced that it has entered into a Cooperative Agreement worth up to $37 million with the Defense Advanced Research Projects Agency (DARPA) to develop an automated instrument that integrates 10 human organs-on-chips to study complex human physiology outside the body. This effort builds on the Institute's past breakthroughs in which Institute researchers engineered microchips that recapitulate the microarchitecture and functions of living organs, such as the lung, heart, and intestine. News releases from two Boston area research centers report that each has received multi-million dollar funding over the next ten years to develop multi-chip simulations of human functions.
Scientists Build Vascular Network Using Sugar and a 3-D Printer
Bioengineers have long dreamed of creating living tissue that can be molded into everything from replacement human livers to lab-grown steaks. But a major obstacle has been keeping engineered tissues alive.
