It typically takes a year to produce hydrocodone from plants, but Christina Smolke and colleagues have genetically modified yeast to make it in just a few days. The technique could improve access to medicines in impoverished nations, and later be used to develop treatments for other diseases.
For thousands of years, people have used yeast to ferment wine, brew beer and leaven bread.
Now researchers at Stanford have genetically engineered yeast to make painkilling medicines, a breakthrough that heralds a faster and potentially less expensive way to produce many different types of plant-based medicines.

A blue glowing device the size of a peppercorn can activate neurons of the brain, spinal cord or limbs in mice and is powered wirelessly using the mouse's own body to transfer energy. Developed by a Stanford Bio-X team, the device is the first to deliver optogenetic nerve stimulation in a fully implantable format.
A miniature device that combines optogenetics – using light to control the activity of the brain – with a newly developed technique for wirelessly powering implanted devices is the first fully internal method of delivering optogenetics.
The device dramatically expands the scope of research that can be carried out through optogenetics to include experiments involving mice in enclosed spaces or interacting freely with other animals. The work is published in the Aug. 17 edition of Nature Methods.

Mounting evidence suggests that concussions in football are caused by the sudden rotation of the skull. David Camarillo's lab at Stanford has evidence that suggests current football helmet tests don't account for these movements.
When modern football helmets were introduced, they all but eliminated traumatic skull fractures caused by blunt force impacts. Mounting evidence, however, suggests that concussions are caused by a different type of head motion, namely brain and skull rotation.
Now, a group of Stanford engineers has produced a collection of results that suggest that current helmet-testing equipment and techniques are not optimized for evaluating these additional injury-causing elements.

Manu Prakash, an assistant professor of bioengineering at Stanford, and his students have developed a synchronous computer that operates using the unique physics of moving water droplets. Their goal is to design a new class of computers that can precisely control and manipulate physical matter.
Computers and water typically don't mix, but in Manu Prakash's lab, the two are one and the same. Prakash, an assistant professor of bioengineering at Stanford, and his students have built a synchronous computer that operates using the unique physics of moving water droplets.

Through special environments called biotic processing units, bioengineers let people interact with cells like fish in an aquarium or even do simple experiments from afar.
In the 1950s, computers were giant machines that filled buildings and served a variety of arcane functions. Today they fit into our pockets or backpacks, and help us work, communicate and play.

The bioengineer and psychiatrist will be honored for his seminal role in the field of optogenetics, which allows scientists to precisely manipulate nerve-cell activity in freely moving animals to study their behavior.
Professor Karl Deisseroth will receive the Albany Medical Center Prize in Medicine and Biomedical Research for his pioneering work in optogenetics.

Researchers from academia, industry and government launch effort to define standards for using bits and pieces of molecular biomachinery to create things such as vaccines, drugs and biosensors.
Just as defining the meter, kilogram and second helped lay the foundation for modern commerce, new measures and standards are needed to fuel the growth of the 21st Century bioeconomy.
The desire to create these new metrics brought more than 100 researchers from academia, industry and government to Stanford University on March 31st to launch a consortium convened by the National Institute of Standards and Technology, or NIST.

Christina Smolke to receive mentor award from Northern California Chapter of Association of Women in Science
Ellen Weaver Award surprises the associate professor of bioengineering, who was nominated by current and former students for helping them balance the demands of research and life.
Stanford bioengineer Christina Smolke was recently delighted and surprised to learn that she had been chosen to receive an award for student mentoring by the Northern California Chapter of the Association for Women in Science (NCC-AWIS).
“I was really touched by this,” Smolke said. “Several of my current and former students put the nomination package together, and I didn’t know about it until I got the email notifying me that I had received this award.”
