A novel device that reprograms skin cells could represent a breakthrough in repairing injured or ageing tissue, researchers say. The new technique, called tissue nanotransfection, is based on a tiny device that sits on the surface of the skin of a living body. An intense, focused electric field is then applied across the device, allowing [...]
When oncologist Dr. Carl June heard the Food and Drug Administration’s decision to bring the first gene therapy to market in the US, he pinched himself, hard. “It was so improbable that this would ever be a commercially approved therapy,” he said, voice breaking with emotion. June was referring to a revolutionary cancer therapy that [...]
By Dr. Sanjay Gupta, Chief Medical Correspondent CNN: Experts say we are "due" for one. When it happens, they tell us, it will probably have a greater impact on humanity than anything else currently happening in the world. And yet, like with most people, it is probably something you haven't spent much time thinking about. After [...]
Space travel can cause a lot of stress on the human body as the change in gravity, radiation and other factors creates a hostile environment. While much is known about how different parts of the body react in space, how lungs are affected by spaceflight has received little attention until now, say researchers at The [...]
From a post by Michael Feldman : Researchers at Argonne National Laboratory are going to be using the Theta supercomputer to generate a map of all the neural connections in a brain. According to a news announcement published on the lab’s website, the project will use high-definition imagery of the brain, along with the computational heft [...]
Incremental progress has been made on several fronts that may employ nanomedical strategies, to potentially counteract the deleterious effects of galactic cosmic rays and microgravity on human physiology. The implementation of these strategies and the enhancement of their preventative, diagnostic, or therapeutic effects for future orbital, planetary, and deep space missions might be enabled [...]
A home pregnancy test is the most common test strip for diagnosis. Pregnant women have progressively increasing levels of the biomarker human chorionic gonadotropin (hCG), which is easily traceable in urine. A thin, colorful strip of antibodies will appear when hCG is present. However, there is much more hCG in urine than there is of [...]
It is envisaged that nanomedicine, beyond the amazing possibilities that may materialize over the next 10-30 years toward advanced diagnostic and therapeutic capacities, might have a far more extensive role than to supplant existing medical technologies and procedures. The larger picture might be manifest via the emergence of a momentous paradigm shift that will have [...]
A Northeastern research team has developed new technology that optimizes DNA sequencing using nanophysics and electric currents. In a paper published in Nature Nanotechnology, Northeastern Professor of Biological Physics Meni Wanunu, in partnership with Pacific Biosciences, a biotechnology company with a focus on DNA sequencing, developed a method for loading DNA into sequencing wells with [...]
From sciencedaily.com: Lawrence Livermore scientists, in collaboration with researchers at Northeastern University, have developed carbon nanotube pores that can exclude salt from seawater. The team also found that water permeability in carbon nanotubes (CNTs) with diameters smaller than a nanometer (0.8 nm) exceeds that of wider carbon nanotubes by an order of magnitude. The nanotubes, [...]
