EDINBURGH, Scotland, March 31, 2014 — A new laser microscope has the potential for a better understanding of the complex brain circuits of people with autism.
Optical Technique Better Measures Blood Coagulation
BOSTON, Feb. 25, 2014 — A new optical approach could help doctors quickly determine a patient’s blood coagulation (clotting) status in near real time.
Graphene Sandwich Improves Biomolecule Imaging
CHICAGO, Feb. 18, 2014 — Atomic-level images of a biological molecule in its natural environment can now be obtained by sandwiching the wet sample between sheets of graphene.
Laser Technique Diagnoses Meningitis
GLASGOW, Scotland, Feb. 14, 2014 — A new laser-based test uses nanoparticles to speed up the diagnosis and treatment of bacterial meningitis, a disease that can lead to blood poisoning and brain damage if not discovered quickly.
Hyperspectral Imaging Reduces Threat of Amputation
SAN FRANCISCO, Feb. 12, 2014 — Hyperspectral imaging (HSI) can help surgeons make quick decisions in the operating room, as it detects issues not visible to the naked eye.
Laser Sensor Speeds Up Salmonella Detection
WEST LAFAYETTE, Ind., Feb. 13, 2014 — A new laser sensor can identify salmonella bacteria in food samples as much as three times faster than conventional detection methods.
Algorithms Enhance Imaging Techniques for Breast Cancer Diagnosis
ATLANTA, Feb. 11, 2014 — A study suggests that tomosynthesis, a technique that can produce pseudo 3-D reconstructions, could top traditional mammography in breast cancer screening and detection. Researchers at Emory University have found that digital tomosynthesis imaging...
Laser Process Shows Promise for Skin Cancer Treatment
CAMBRIDGE, Mass., Feb. 7, 2014 — The treatment of basal-cell carcinoma (BCC) with a new combination of lasers – pulsed dye and Nd:YAG – has yielded some good results, offering the potential for nonsurgical treatment.
Lens-Free Imaging Targets Metastatic Cancer Cells
LOUVAIN, Belgium, Feb. 3, 2014 — Lens-free digital imaging could be key in earlier detection of the spread of highly aggressive cancer cells, greatly improving a patient's chance of survival.
Noninvasive Optical System Reveals Oral Cancer Signs
KERALA, India, Jan. 29, 2014 — A new spectral imaging system holds promise for rapid, noninvasive screenings for oral cancers.

BOSTON, Jan. 13, 2014 — A bio-inspired, light-activated adhesive used to treat congenital heart defects could soon replace more invasive treatments such as sutures, new research indicates.
Lighting Up Brain Stops Liquored-Up Rats
BUFFALO, N.Y., Jan. 7, 2014 — Stimulating brain cells with light stops binge drinking in rodents, a new study finds. The results suggest the possibility of using optogenetics to treat substance abuse, neurological diseases and mental illnesses.
Imaging Technology Could Unlock Mysteries of a Childhood Disease
ATLANTA, Jan. 2, 2014 — A superresolution imaging technique that allows the structure of a respiratory virus to be seen in living cells could help unlock the virus’s secrets, including how it enters cells and replicates, and why certain lung cells escape relatively...
Laser-Driven Nanobubbles Noninvasively Detect Malaria
HOUSTON, Jan. 2, 2014 — A noninvasive, laser scanner “vapor nanobubble” technology using no dyes or diagnostic chemicals can detect even a single malaria-infected cell among a million normal cells, with zero false-positive readings. The transdermal diagnostic...
Handheld OCT Device Catches Eye Disease Early
CAMBRIDGE, Mass., Dec. 23, 2013 — A handheld optical device that combines ultrahigh-speed 3-D imaging with a microelectromechanical systems (MEMS) scanning mirror could make early detection of certain eye diseases as easy as scanning a bar code. Photographs of the power grip style...
