Night Vision, Laser Imaging Enhance Lymphatic Studies
HOUSTON, June 5, 2014 — Better imaging of the lymphatic system is now possible using IR techniques, allowing earlier detection of cancer and lymphedema. It could also lead to more effective, manageable treatment of such diseases. A new technology, developed by a team from the University of Texas Health Science Center at Houston (UTHealth) Medical School, is able to image the human lymphatic system in real time without the need for radioactive compound injections. The near-infrared fluorescence laser imaging
Light Mitigates Alzheimer’s Symptoms
TROY, N.Y., June 4, 2014 — Those suffering from Alzheimer's disease and dementia could soon find some relief thanks to a developing light treatment. A new study by researchers at Rensselaer Polytechnic Institute shows that daytime light treatment could improve sleep and...
Laser Triggers Stem Cells to Fix Teeth
CAMBRIDGE, Mass., May 29, 2014 — A new low-light laser technique has shown the potential to regrow tooth cells. A team led by Harvard University has discovered that low-power light can prompt stem cells to regenerate tissue inside the body. This shows promise for regenerative...
Optical Scanner Shines New Light on Brain
ST. LOUIS, May 21, 2014 — A new generation of optical neuroimaging touts effectiveness comparable to MRI and PET technologies, but has the ability to see and study areas of the brain that the others cannot. Diffuse optical tomography (DOT) is a new brain scanning technology...
Neuronal Imaging System Shows Bigger 3-D Picture
CAMBRIDGE, Mass., and VIENNA, May 19, 2014 — A new technique could lead to a better understanding of how neuronal networks process sensory information and even how behavior is created in the brain. A team from MIT, the University of Vienna and the Research Institute of Molecular Pathology has...
Combined Imaging, Treatment Regime Targets Tumors
CINCINNATI, May 15, 2014 — Certain types of brain tumors are difficult to image and detect, making them even more difficult to treat. A team from the Cincinnati Cancer Center and the University of Cincinnati Cancer Institute has discovered a new approach to in vivo imaging of...
Fluorescent Tool Shows Nanoparticles Biodegrade in Real Time
PHILADELPHIA, April 29, 2014 — A recent study using Förster resonance energy transfer (FRET) to chart the disintegration of nanoparticles in living tissue in real time could aid the development of safe nano-drug delivery methods. “Nanoparticles are made with very...
Optogenetic Switch Now Works Both Ways: On and Off
STANFORD, Calif., April 24, 2014 — Since the beginning of optogenetics, the technique has been more effective at switching neurons on than off -- but not anymore. Building from Dr. Karl Deisseroth’s discovery about a decade ago of optogenetics — in which light-activated...
3-D Cell Imaging Through Microfluidic Channels
CAMBRIDGE, Mass., March 26, 2014 — A microscopy technique developed in 2007 by scientists at MIT enabled 3-D imaging of the interior of living cells without using fluorescent or other markers. Recent adaptations have taken this a step further.
Creation of Living Materials Shows Potential
CAMBRIDGE, Mass., March 25, 2014 — A new approach to materials synthesis has shown promise in the creation of living elements.
Optical Brain Monitoring for Better Stroke Care
PHILADELPHIA, March 20, 2014 — Advanced technology and simple body positioning could be key in providing acute stroke patients with more effective, individualized treatment in real time.
High-Tech Glasses Show Cancer Cells
ST. LOUIS, March 14, 2014 — Distinguishing between cancer cells and healthy cells could become easier for surgeons. And all they'll need to do is put on glasses.
Diffractive Catheter Enhances OCT Imaging
BALTIMORE and SEATTLE, March 12, 2014 — A new imaging catheter that enables real-time, ultrahigh-resolution OCT imaging at 800 nm to form a 3-D volumetric dataset could potentially improve image contrast via increased light scattering and less tissue absorption.
New Technique Visualizes Live Cells
NEW YORK, March 3, 2014 — A new optical imaging platform represents a significant step toward a longstanding scientific goal: visualizing small biomolecules inside living biological systems with minimum disturbance.
US Research Spending Decline Driven By Industry
ANN ARBOR, Mich., Jan. 2, 2014 — A sharp drop in US spending on biomedical research has been driven almost entirely by reduced investments from industry, not the public sector, a new study finds. The US’s global share of biomedical research spending fell from 51 percent in...
Injectable microLEDs Turn Light On in Brain
CHAMPAIGN, Ill., April 15, 2013 — Microscopic LEDs injected deep inside the brain are the latest probe for triggering targeted neurons, providing insight into the brain’s structure, function and complex connections.
With Laser Zap, Cocaine Addiction Vaporizes
SAN FRANCISCO, April 8, 2013 — Laser light stimulation to a portion of the brain can wipe away addictive behaviors — or conversely turn on a drug addiction, a new US study on rats has demonstrated.
Light and Color Measure Cell O2 in Real Time
ST. LOUIS, March 27, 2013 — A real-time technique that uses light and color to measure oxygen delivery to individual red blood cells could enable researchers to study the process in relation to diseases and their treatments.
Boston Micromachines Wins Adaptive Optics NIH SBIR Grant
CAMBRIDGE, Mass., March 14, 2013 — Boston Micromachines Corp. (BMC) has received a $1.2 million National Institutes of Health (NIH) grant to fabricate a retinal imaging system using microelectromechanical systems (MEMS)-based deformable mirrors for wavefront correction.
The other side of the apocalypse
Dec 28, 2012 — We seem to have survived the end of the world, though we can hardly say we’ve survived it unscathed. Even in the context of an already difficult year, the past several months have felt like a brickbat to the head. A bruising campaign season...
SPIE Urges Leaders to Avoid Fiscal Cliff, Support Science
BELLINGHAM, Wash., Dec. 12, 2012 — What do we want? A bipartisan plan to avoid the fiscal cliff that also supports science and education. When do we want it? Now.
Lumetrics to Develop Handheld Eye Scanner
ROCHESTER, N.Y., Nov. 22, 2012 — A pen-sized eye scanner could improve access to vision-related health care in the US and around the world, thanks to a grant issued by the National Institutes of Health (NIH) to Lumetrics.
NIH Awards Vixar VCSEL Contract
PLYMOUTH, Minn., Sept.26, 2012 — Optoelectronic components and subassemblies supplier Vixar has received an SBIR Phase I contract from the National Institutes of Health to demonstrate the feasibility of a wavelength-tunable vertical-cavity surface-emitting laser.
Method ‘Tags and Tracks’ DNA Looping
DALLAS, Aug. 20, 2012 — A “tag and track” method using fluorescent molecules not only sheds light on how DNA loops form, but also might be adapted to screen drugs for effectiveness against certain viruses that shuffle genetic material, such as HIV.
The Ongoing Struggle Over Translational Research
Aug 1, 2012 — If the National Center for Advancing Translational Science were a person with feelings and a fragile sense of self-worth, it might be feeling snubbed and even a bit wounded these days. Sure, the Obama administration’s budget proposal released...
