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 ...
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 ...
August 8, 2018 Blue light from digital devices and the sun transforms vital molecules in the eye’s retina into cell killers, according to optical chemistry research at The University of Toledo. The process outlined in the study, which was recently published in the journal Scientific Reports, leads to age-related macular degeneration, a leading cause of […]Continue Reading ...
Any thought you’ve ever had, any motion you’ve ever made, any twinge of pain you’ve ever felt is the result, in part, of neurons in the brain and throughout your body sending chemical signals from one to the next. Now, Stanford scientists are a step closer to actually watching those signals as they take shape […]Continue Reading ...
July 6, 2018 The UK based developer of next generation proton therapy technology, Advanced Oncotherapy plc (AVO), has selected RayStation as its treatment planning system for the first LIGHT (Linac Image Guided Hadron Technology) system at the proton therapy facility under construction at Harley Street in central London. Users at the clinic will have access […]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 ...
August 7, 2018 Light therapy (phototherapy) is used to treat sleep disorders, depression, and seasonal mental disorders. In order to study its effects on the cardiovascular system (especially in case of stable increase in blood pressure) and to make phototherapy safer for patients suffering from hypertension, experts from RUDN University were carrying out experiments on […]Continue Reading ...
July 18, 2018 Settling youngsters down to sleep at night isn’t always easy. Recent research suggests that the amount of exposure children have to bright light in the hour leading up to bedtime -; whether emanating from light bulbs or electronic devices -; can have a big impact on sleep-related behavior. There’s chemistry behind it. […]Continue Reading ...
June 27, 2018 Tommy John surgery, or reconstruction of the ulnar collateral ligament (UCL) in the elbow, has been dubbed an epidemic among Major League Baseball pitchers. A mechanical engineer at Washington University in St. Louis plans to develop a bioinspired imaging technique to study how damage accumulates in the UCL during loading, or the […]Continue Reading ...
