A team of scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), in collaboration with researchers from Monash University Australia, has succeeded in significantly increasing the stability and biocompatibility of special light-transducing nanoparticles. The team has developed the so-called “upconverting” nanoparticles that not only convert infrared light into UV-visible light, but also are water-soluble, remain stable in complex […]Continue Reading ...
Exposure to blue light decreases blood pressure, reducing the risk of developing cardiovascular disease, a new study from the University of Surrey and Heinrich Heine University Dusseldorf in collaboration with Philips reports. During this study, published in the prestigious European Journal of Preventative Cardiology, participants were exposed to 30 minutes of whole-body blue light at […]Continue Reading ...
Oct 25 2018 AXT has recently been appointed the local distributor for Phi Optics, an innovative developer of Quantitative Phase Imaging (QPI) solutions for live cell and tissue microscopy. Phi Optics’ modular solutions have been designed as simple add-ons for existing inverted light microscopes giving them detailed analytical capabilities. Phi Optics GLIM Gradient Light Interference […]Continue Reading ...
When treatment is working for a patient who is fighting cancer, the light at the end of the tunnel is easier to see. However, with metastatic breast cancer, the prognosis can be a bit disheartening with poor outcomes for patients. This is why Nalinikanth Kotagiri, MD, PhD, assistant professor in the James L. Winkle College […]Continue Reading ...
In any seemingly quiet pond, the still waters actually teem with tiny pond dwellers called Euglena gracilis. Unseen to the naked eye, the single-celled organism spirals through the water, pulled along a relatively straight path by a whiplike appendage, in search of just the right level of light. But Stanford researchers have discovered how, under some […]Continue Reading ...
Sep 25 2018 Ground-breaking technology unlocks rapid and simple label-free 3D and 4D live cell imaging A novel optical microscope utilizing diffraction tomography to generate 3D holographic images of unlabeled live cells is now available from Tomocube. Called HT-1, the new microscope delivers quantitative nanoscale, real-time, dynamic images of individual living cells quickly and simply […]Continue Reading ...
A single UVC light-diffusing optical fiber may be able to prevent infections around skin-penetrating medical devices. (Photo credit: David Welch, PhD)) A specific wavelength of ultraviolet light, now delivered through light-diffusing optical fibers, is highly effective at killing drug-resistant bacteria in cell cultures, according to a new study led by David J. Brenner, PhD, a […]Continue Reading ...
By Dr Ananya Mandal, MDAugust 10, 2018 According to researchers, the blue light from laptops, smart phones and other digital devices, could raise the risk of blindness. The study appears in the latest issue of the journal Scientific Reports. Image Credit: OHishiapply / Shutterstock The new study comes from a team of researchers at the […]Continue Reading ...
Scientists at Johns Hopkins Medicine say they have identified what may be an ancient light-sensing mechanism in modern mouse retinal cells. “Some evolutionary biologists have proposed that ancient organisms may have had two separate light-response mechanisms that coexisted in a single photoreceptor, and through evolution, these two mechanisms separated into different cell types. Our research […]Continue Reading ...
Oct 25 2018 WHO: Excelitas Technologies® Corp., a global technology leader delivering innovative, customized photonic solutions, will display its wide range of X-Cite® fluorescence illumination products for microscopy at Neuroscience 2018. WHAT: Products on display at Excelitas’ Neuroscience Booth #2529 include: X-Cite XYLIS: X-Cite XYLIS for fluorescence microscopy features Excelitas’ patented LaserLED Hybrid Drive® and […]Continue Reading ...
Farsightedness, also known as hyperopia, is an eye condition that causes blurry near vision. People who are farsighted have more trouble seeing things that are close up (such as when reading or using a computer) than things that are far away (such as when driving). For normal vision, light passes through the clear cornea at […]Continue Reading ...
Researchers developed fluorescent proteins that can be controlled by orange and green light. These proteins will help to study processes in living cells. The work was supported by Russian Science Foundation (RSF) grant, and the results were published in Nature Methods. Fluorescent proteins emit intense visible light with wavelengths ranging from 390 to 700 nm. […]Continue Reading ...
Sep 14 2018 The Bl-200SM Research Goniometer System from Testa Analytical Solutions e.K. is a precision instrument designed for exacting Static Light Scattering (SLS) and Dynamic Light Scattering (DLS) measurements. Based on a special turntable with precision ball bearings and stepping motor, the Bl-200SM’s modern design and quality construction guarantee precise measurements due to the […]Continue Reading ...
A specific wavelength of ultraviolet light, now delivered through light-diffusing optical fibers, is highly effective at killing drug-resistant bacteria in cell cultures, according to a new study led by David J. Brenner, PhD, a professor of radiation biophysics at Columbia University Vagelos College of Physicians and Surgeons. The technology is designed to prevent infections around […]Continue Reading ...
August 9, 2018 From day one, Robert McMichael has been determined to live the best life he can. Born with muscular dystrophy, he refused to let his physical challenges block his path to achievement and completed medical school and a demanding residency in neurology. When the Mansfield physician was diagnosed with bladder cancer about a […]Continue Reading ...
