Stanford bioengineers create circuit board modeled on the human brain
Stanford bioengineers have developed faster, more energy-efficient microchips based on the human brain - 9,000 times faster and using significantly less power than a typical PC. This offers greater possibilities for advances in robotics and a new way of understanding the brain. For instance, a chip as fast and efficient as the human brain could drive prosthetic limbs with the speed and complexity of our own actions.
Stanford bioengineers make it easier to see inner workings of the brain
Stanford bioengineers have announced improvements on a technique, which they had pioneered previously, that allows researchers to view intact brain structures. This technique produces spectacular "fly-through" views of the brain's neural connections.

Smartphone Apps for World Health
Two TED talks describe projects already or nearly deployed in the field, which help save the lives of people living in situations remote from medical care. Using only smartphones with special apps and simple interface gear, remarkable diagnostic results are available. First is Saving Lives, One Phone at a Time, featuring a continuous wearable ECG monitor, including some diagnostic capabilities, which is targeted at the burgeoning cardiac disease problem in India. The second is Get Your Next Eye Exam on a Smartphone, which aims to detect and prevent curable eye diseases in rural areas of Kenya. Take a look at these inspiring videos!

Bioengineer designs a diagnostic microscope costing less than $1
In many developing countries, microscopes aren't available in remote areas, because of the cost. But they are essential for the rapid diagnosis of infectious diseases. An enterprising bioengineer has devised a "Foldoscope" that can be produced for less that $1, and can even be discarded after each use.

Engineering a more efficient way to diagnose prostate cancer
A multidisciplinary team from the University of Michigan is working on developing a faster and more cost effective way to evaluate biomarkers to diagnose cancer using computational models. They sift through vast medical databases and apply engineering methods to assess the most effective predictors of prostate cancer.

Robotic Biopsy Demonstrated
Two MIT graduate students, Conor Walsh and Nevan Hanumara, helped design the Robopsy machine, a robotic device that holds a biopsy needle and is so lightweight it can sit on a patient's chest during a CT scan. The mechanical engineering graduate students worked with Professor Alexander Slocum (MIT) and Massachusetts General Hospital radiologist Rajiv Gupta to design the invention they hope will cut both time and complications from a typical lung biopsy.

Human Lung on a Chip
Researchers at the Wyss Institute of Harvard University have been conducting research on how to mimick vital human organs on a chip. One of the goals in this research is to improve the drug screening process. They have produced a lung-on-a-chip which exhibits respiration and mimicks pulmonary edema.

Better Analytical Tools for Genome Researchers
Researchers are developing big data techniques for large-scale DNA analysis. Next-Generation-Sequencing (NGS) techniques are revolutionizing the sequencing of DNA, greatly increasing the speed and decreasing the cost. But the mountains of data produced by sequencers can swamp current computing platforms. 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.
Check Your Vitals on Your Smartphone
Scanadu, a 2-year-old San Francisco startup aiming to develop a handheld medical scanner for home use, similar to the Star Trek tricorder, has unveiled the SCOUT, set for release by the end of 2013. The NASA Ames Research Center-based company says that customers simply hold the small, lightweight device to the patient's temple and it will return five vital sign results with 99 percent accuracy in less than 10 seconds. Read the story, and see a trailer of Scanadu's vision for the SCOUT, and several other devices. Follow the link below to the article on the IEEE Spectrum.
Does the Brain Work Logarithmically?
In a new IEEE Spectrum "Techwise Conversations" video presentation, Steven Cherry interviews Dr. Lav Varshnev of IBM, who points out that new research has found a neurobiological basis for understanding logarithmic compression in the brain. The concept has been around for over 100 years (in the Weber-Fechner law describing perceived sensitivity to stimuli), but now is being used in a variety of new ways.
A Robot Ankle for Amputees
The BiOM, one of the world's most advanced ankles, comes from the cutting-edge prosthetics company iWalk. The company was founded by MIT professor Hugh Herr, who directs the biomechatronics group at the MIT Media Lab. IEEE Spectrum visited iWalk's headquarters in Bedford, Mass., to see its BiOM ankle in action and to learn more about how it works.
DARPA Funds Human-On-A-Chip project
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. Cells need a constant supply of nutrients and oxygen, and engineering a blood vessel system to deliver those nutrients and remove waste has remained elusive. Researchers at University of Pennsylvania say they may have found a way to create vasculatures using sugar and a 3-D printer.
