3D Liquid-Cell Electron Microscopy Imaging Now Possible
Electron microscopy revealed a world that exists at scales smaller than the wavelength of light. Advancements in this field have allowed scientists to visualize ever more objects and processes, but actually seeing living cells in 3D and within a liquid environment has been impossible. Now, a team of researchers from Penn State University, Virginia (Read more...)
Postoperative Adjustment of Intraocular Lenses Holds Promise
When ophthalmologists calculate intraocular lens power for cataract surgery patients, they should consider the cornea, but postoperatively adjustable lenses could be the way of the future. Medscape Medical News
Lens Adjustment After Cataract Surgery in View
When specialists calculate intraocular lens power for patients undergoing cataract surgery, they should consider the cornea, but postoperatively adjustable lenses could be the way of the future. Medscape Medical News
AI Sparks Legal Debate Over Machine-Generated Mistakes
Specialists are figuring out where computers belong in the healthcare system, how reimbursement will work, and who is legally liable when machines make mistakes. Medscape Medical News
Nobel Prize in Physiology or Medicine 2019 Announced for Cell Oxygen Regulation
Two Americans and an English knight have won this year’s Nobel Prize in Physiology or Medicine for their discovery of how cells detect how much oxygen is available to them and the mechanism that regulates how they adapt to changes in oxygen levels. While the scientific community recognized the importance of oxygen for animal cells […]

Discreet Wearable for Hair Regrowth Using Body-Generated Electricity
While there are some devices and medications out there to help slow hair loss and regrow hair, they’re bulky, uncomfortable, or have substantial side effects. Low-frequency electric stimulation, delivered in pulses and over extended time periods, has a great deal of potential as an effective way to promote hair growth. The problem is that it (Read more...)
Measuring Pain Levels Using Functional Near Infrared Spectroscopy
Knowing how much pain a patient is in can help clinicians to diagnose a condition, understand the course of a disease, and set a course for treatment. While simply hearing patients out works pretty well for the general population, unconscious and non-communicative people are not properly assessed all too often. Now, researchers from MIT, Harvard, [ (Read more...)
Multicolor Activated Fluorescent Dyes Thanks to Single Atom Replacement
Fluorescent dyes have transformed biomedical science. The Nobel Prize in Chemistry for 2008, for example, was given for the discovery and development of green fluorescent protein, GFP. Ever since GFP became available, scientists have been working on improving fluorescent dyes to better study dynamic processes within biological tissues. Typically, u (Read more...)
