Device is used to monitor brain pressure in lab mice as prelude to possible use with human patients; future applications of this pressure-sensing technology could lead to touch-sensitive “skin” for prosthetic devices.
Stanford engineers have invented a wireless pressure sensor that has already been used to measure brain pressure in lab mice with brain injuries.
The underlying technology has such broad potential that it could one day be used to create skin-like materials that can sense pressure, leading to prosthetic devices with the electronic equivalent of a sense of touch.

Stanford engineers developing miniature wireless device to create better way of studying chronic pain
A team of Stanford engineers is creating a small wireless device that will improve studies of chronic pain. The engineers hope to use what they learn to develop better therapies for the condition, which costs the economy $600 billion a year.
Ada Poon, a Stanford assistant professor of electrical engineering, is a master at building minuscule wireless devices that function in the body and can be powered remotely. Now, she and collaborators in bioengineering and anesthesia want to leverage this technology to develop a way of studying – and eventually developing treatments for – pain.

Stanford engineers are working to create a flu vaccine that could be produced more quickly and offer broader protection than what is available today.
Every year the approach of flu season sets off a medical guessing game with life or death consequences. There are many different strains of flu, and they vary from year to year. So each season authorities must make an educated guess and tell manufacturers which variants of the flu they should produce vaccines against.
Even when this system works, flu-related illnesses can kill 3,000 to 49,000 Americans annually, according to the Centers for Disease Control and Prevention. A bad guess or the unexpected emergence of a virulent strain could send the death toll higher.

Drew Endy named an Open Science Champion of Change.
Drew Endy, a synthetic biologist and assistant professor of bioengineering, has been honored by the White House as part of its Champions of Change Open Science program, which recognizes those who promote and use “open scientific data and publications to accelerate progress and improve our world.”

Stanford bioengineers have transformed an intact, post-mortem mouse brain into a transparent three-dimensional structure that keeps all the fine wiring and molecular structures in place. Known as CLARITY, the technique stands to transform our understanding of the brain and indeed of any biological tissue.
Combining neuroscience and chemical engineering, researchers at Stanford University have developed a process that renders a mouse brain transparent. The postmortem brain remains whole — not sliced or sectioned in any way — with its three-dimensional complexity of fine wiring and molecular structures completely intact and able to be measured and probed with visible light and chemicals.

The Brain Research through Advancing Innovative Neurotechnologies (BRAIN) project, which calls for initial federal funding of $100 million, will make use of several innovative technologies invented by Stanford scientists.
President Barack Obama announced today a bold research initiative aimed at developing new technologies and methods for understanding the human brain. Several Stanford scientists will play critical roles in the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) project, which calls for initial funding of $100 million.

A team of Stanford University bioengineers has taken computing beyond mechanics and electronics into the living realm of biology. They have developed a biological transistor made from genetic material — DNA and RNA. The team calls its invention the “transcriptor.”
When Charles Babbage prototyped the first computing machine in the 19th century, he imagined using mechanical gears and latches to control information. ENIAC, the first modern computer developed in the 1940s, used vacuum tubes and electricity. Today, computers use transistors made from highly engineered semiconducting materials to carry out their logical operations.

Engineers at Stanford have developed a prototype single-fiber endoscope that improves the resolution of these much-sought-after instruments fourfold over existing designs. The advance could lead to an era of needle-thin, minimally invasive endoscopes able to view features out of reach of today’s instruments.
Engineers at Stanford have demonstrated a high-resolution endoscope that is as thin as a human hair with a resolution four times better than previous devices of similar design. The so-called micro-endoscope is a significant step forward in high-resolution, minimally invasive bio-imaging with potential applications in research and clinical practice. Micro-endoscopy could enable new methods in diverse fields ranging from study of the brain to early cancer detection.

Cafe Scientifique: Is the Genome Useful in Medicine?
– with Stephen Quake, PhD, Professor of Bioengineering and Applied Physics, Stanford University
We are living in the genome age, where the productivity of DNA sequencers is advancing faster than Moore's Law. Dr. Quake will describe the development of the first single molecule DNA sequencer. He will then go on to discuss several applications of high throughput DNA sequencing in medicine, ranging from non-invasive diagnostics to the first clinically annotated human genome.

Stanford Professor Karl Deisseroth joins a super-team of scientists to propose the Brain Activity map, a collaborative initiative akin to the Human Genome Project, to better understand how the brain works.
Neuroscience has come a long way since the Roman physician Galen prodded gladiators' head wounds and surmised that the brain, and not the heart, was the home of human intelligence. Nowadays, scientists can create three-dimensional maps of intact neuronal networks, observe individual neurons firing in real time within animals, and even control how those neurons fire using a technique that involves gene therapy and lasers.
