Solar cell-like implant stimulates optic nerve
STANFORD, Calif. – A new retinal prosthesis that uses technology similar to that found in solar cells could restore sight to those who suffer from degenerative eye diseases such as macular degeneration and retinitis pigmentosa. Researchers at Stanford University School of Medicine have developed goggles that interface with a tiny chip in the retina and convert light into electrical signals, stimulating the optic nerve and allowing patients to see once more. “While high-fidelity color vision is a...
Silicon Implant Aims to Restore Sight
STANFORD, Calif., May 14, 2012 — A new type of retinal prosthesis, which uses technology similar to that found in solar cells, could hold the key to those who suffer from degenerative eye diseases like macular degeneration and retinitis pigmentosa. Researchers at the Stanford...

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...
$1.8M Grant Funds Adaptive Optics Study for Glaucoma
HOUSTON, Feb. 3, 2012 — A $1.85 million NIH grant will support a study to determine the effectiveness of adaptive optics in capturing the earliest cellular changes signaling the onset of glaucoma, which may lead to earlier diagnosis of the blinding disease.
Funding reauthorization will stabilize SBIR programs
BELLINGHAM, Wash. – The US House committee leaders and the Senate recently reached an agreement to reauthorize funding for the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs for another six years, which will help to...
SPIE Applauds Congress for Six-Year SBIR Reauthorization
BELLINGHAM, Wash., Dec. 28, 2011 — SPIE is pleased with the recent six-year reauthorization by Congress of the federal Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs. The SBIR/STTR programs are designed to spur technology innovation...
Updated PDT Targets, Destroys Cancer Cells
BETHESDA, Md., Nov. 18, 2011 — A new form of photodynamic therapy dubbed photoimmunotherapy, or PIT, destroys cancer cells in mice without harming surrounding normal tissue. This light-based cancer therapy technique could theoretically work against tumors in humans, such as those...
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,...
Light antennas assemble themselves
TORONTO – New photosynthesis-inspired nanomaterials can control and direct energy absorbed from light – and can even build themselves into light-harvesting antennas. For years, nanotechnologists have been intrigued by quantum dots, but they have...
Laser Measures Protein Interactions
NASHVILLE, Tenn., March 18, 2011 — A laser technique that can measure interactions between proteins tangled in a cell’s membrane is expected to help in the discovery of new drugs. About 30 percent of the 7000 proteins in a human cell reside in its membrane, initiating 60...
Researchers to NIH: “If It Ain’t Broke…”
Feb 3, 2011 — Investigators in optical imaging and other biomedical fields are troubled by developments at the National Institutes of Health, where the creation of a new research center will lead to the dismantling of an older one, which many look upon as an...
MRI Advance Speeds Brain Scans
BERKELEY, Calif., Jan. 17, 2011 — A breakthrough in magnetic resonance imaging that allows brain scans more than seven times faster than currently possible was reported by an international team of physicists and neuroscientists. A University of California, Berkeley physicist...
Esophageal Cancer Detected with Light
DURHAM, N.C., Jan. 10, 2011 — A tiny light source and sensors at the end of an endoscope may provide a more accurate way to identify pre-cancerous cells in the lining of the esophagus. Developed by biomedical engineers at Duke University and successfully tested on patients...
