Arresting Epileptic Seizures with Fiber Optics
IRVINE, Calif., Jan. 28, 2013 — Unpredictable epileptic seizures can now be stopped in their tracks with a new approach that activates optical fibers implanted in the brain when a computer system detects a real-time seizure.
Photonics West Boasts Largest Program Yet
SAN FRANCISCO, Dec. 13, 2012 — SPIE Photonics West will set records again this year, thanks to its largest-ever biomedical technical program and BiOS Expo, which are driving growth for the 2013 event, SPIE said.
A 3-D Light Switch for the Brain
CAMBRIDGE, Mass., Nov. 19, 2012 — A new tool that delivers precise points of light to living brain tissue in three dimensions could one day help treat Parkinson’s disease and epilepsy; it could even aid in the understanding of consciousness and how memories form.
Muscles Get a ‘Light’ Workout
CAMBRIDGE, Mass., Sept. 12, 2012 — Genetically engineered muscle cells have been made to flex in response to light, a step toward using such light-sensitive tissue to build highly articulated robots.
Optogenetics Pioneers Win Zülch
COLOGNE, Germany, Sept. 6, 2012 — Four scientists who initiated and were instrumental in promoting optogenetics will be recognized Sept. 7 with the K.J. Zülch Prize 2012 from the Gertrud Reemtsma Foundation. In announcing the prize recipients — Ernst Bamberg of Max Planck...
Robot Reveals Inner Workings of Brain Cells
ATLANTA, May 10, 2012 — A robotic arm guided by a cell-detecting computer algorithm analyzes and records information from neurons present in the living mouse brain with better accuracy and speed than a human experimenter. The automated method could help scientists classify...
Boyden Awarded Inaugural International Prize
LONDON, May 2, 2012 — Professor Ed Boyden received the first international £300,000 A. F. Harvey Prize from the Institution of Engineering and Technology for his pioneering research in medical engineering.
MIT Triggers Total Fear Recall in Mice
CAMBRIDGE, Mass., March 27, 2012 — An optogenetic technique that uses light to target specific populations of neurons in the brain was used to make mice recall fear memories and respond by freezing. Scientists at MIT used the technique to learn whether memory traces, known as memory...
BiOS Expo Continues to Grow
SAN FRANCISCO, Nov. 11, 2011 — Continuing its growth trend, the biomedical optics (BiOS) Expo at SPIE Photonics West is expected to be bigger than ever in 2012, with the number of exhibiting companies up 15 percent over last year. Technical topics will include enabling...
NIH Grants $12.5M for Optogenetics, Imaging, Tumor Detection
PHILADELPHIA, Oct. 6, 2011 — Three labs at the University of Pennsylvania have received $12.5 million from the National Institutes of Health (NIH) to pursue light-driven ideas expected to advance medical research. These awards are granted under the NIH’s Pioneer,...
Human Heart Cells Paced with Light
STANFORD, Calif., Sept. 23, 2011 — The first human heart cells that can be paced with light were created at Stanford University, providing new insight into the vital organ’s function.
Biological Pacemaker Triggered by Light
STONY BROOK, N.Y., Aug. 18, 2011 — A new method of stimulating heart muscle cells could lead to the creation of pacemakers that are remotely controlled with low-energy light. Employing optogenetics, researchers at Stony Brook University introduced light-sensitive proteins into cells,...
Nerve Cells Controlled via Light Pulses
FRANKFURT, Germany, April 11, 2011 — Using channelrhodopsins — ultralight-sensitive membrane proteins that can be inserted into cell membranes — researchers now can precisely control nerve cell activity with weak light pulses. Because channelrhodopsin has a slightly...
Guide Star Sees Deep into Human Tissue
ST. LOUIS, Feb. 14, 2011 — Astronomers have a neat trick they sometimes use to compensate for the turbulence of the atmosphere that blurs images made by ground-based telescopes. They create an artificial star called a guide star and use its twinkling to compensate for the...
LCD Projector Controls Tiny Worms
ATLANTA, Jan. 24, 2011 — Researchers are using inexpensive components from ordinary LCD projectors to control the brain and muscles of tiny organisms, including freely moving worms. Red, green and blue lights from a projector activate light-sensitive microbial proteins that...
The Road to P West
Jan 10, 2011 — I may have mentioned a time or two before: I am an inveterate road tripper, an unapologetic bird of passage, an excursionist in the grand arcades and back alleys of mythic America. In my book no motel is too seedy, too riddled with bullet holes. And...
Light Workout: Optogenetics Stimulates Mouse Muscles
STANFORD, Calif., Sept. 27, 2010 — Light has been used to effectively stimulate muscle movement in mice optically, rather than electrically. In a study involving bioengineered mice whose nerve-cell surfaces are coated with special light-sensitive proteins, researchers at...
Applications abound for newly licensed microLEDs
STRATHCLYDE, UK – Communications and life sciences can expect a boost from a newly formed company in Glasgow. In a spinout deal, the University of Strathclyde has formed mLED Ltd., a company dedicated to promoting its newly licensed microLEDs, dense arrays of up...
Light Silences Brain Cells
CAMBRIDGE, Mass., Jan. 6, 2010 – Neuroscientists at MIT developed a powerful new class of tools to reversibly shut down brain activity using different colors of light. When targeted to specific neurons, such tools could lead to new treatments for the abnormal activity associated...
Light offers read-and-write access to brain cells
OXFORD, UK – A new set of methods allows experimental interaction with biological systems composed of many interacting cell types, such as neural circuits in the brain. Researchers at the University of Oxford have used light to manipulate the memories of fruit...
Lasers Twist Fly Memories
OXFORD, England, Oct. 19, 2009 -- Light has been used to manipulate the memories of fruit flies, allowing them to learn from mistakes they never made and scientists to pinpoint the nerve cells that regulate such actions. The work could provide valuable information about how memories...
FiO Hot Topics: Hot Optics
SAN JOSE, Calif., Oct. 13, 2009 -- New types of research that explore breakthroughs in medical imaging, solar power, communications and vision were presented during "What's Hot in Optics Today?" during Frontiers in Optics 2009 (FiO) Sunday. About 100 conference early birds gathered...

Lasers Induce Brain Waves
CAMBRIDGE, Mass., April 27, 2009 – Researchers at MIT used a new technology called optogenetics, which combines genetic engineering with light to manipulate the activity of individual nerve cells, to induce gamma waves in mouse brains. The resulting information about neuron function...
