Melanoma in skin biopsy with H&E stain — this case may represent superficial spreading melanoma. Credit: Wikipedia/CC BY-SA 3.0 Researchers at Tel Aviv University have developed a novel nano-vaccine for melanoma, the most aggressive type of skin cancer. Their innovative approach has so far proven effective in preventing the development of melanoma in mouse [...]
You know you have a skeleton, but did you know that your cells have skeletons, too? Cellular skeletons, or cytoskeletons, are shapeshifting networks of tiny protein filaments, enabling cells to propel themselves, carry cargo, and divide. Now, an interdisciplinary team of Caltech researchers has designed a way to study and manipulate the cytoskeleton in [...]
Modern light microscopic techniques provide extremely detailed insights into organs, but the terabytes of data they produce are usually nearly impossible to process. New software, developed by a team led by MDC scientist Dr. Stephan Preibisch and presented in Nature Methods ("BigStitcher: Reconstructing high-resolution image datasets of cleared and expanded samples"), is helping researchers [...]
It has long been known that gold can be used to do things that philosophers have never even dreamed of. The Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow has confirmed the existence of 'gold glue': bonds involving gold atoms, capable of permanently bonding protein rings. Skilfully used by an [...]
Finding out you have cancer is bad enough, but to then have to go to hospital for a painful and invasive biopsy to try to identify the exact type of tumor can be deeply traumatic. But that may soon be a thing of the past: new, cheap devices the size of a silicon chip [...]
DARPA has awarded funding to six organizations to support the Next-Generation Nonsurgical Neurotechnology (N3) program, first announced in March 2018. Battelle Memorial Institute, Carnegie Mellon University, Johns Hopkins University Applied Physics Laboratory, Palo Alto Research Center (PARC), Rice University, and Teledyne Scientific are leading multidisciplinary teams to develop high-resolution, bidirectional brain-machine interfaces for use [...]
Source: Bold Business. Follow them on twitter. Though you may not realize it, more than 40,000 computer-brain interfaces have already been employed in healthcare today. Thus, to say computer-brain interfaces are something new would be inaccurate. But compared to what the future of neuromedicine holds, these types of interfaces are quite rudimentary. The real [...]
It is hard to imagine just how small one nanometer—one-billionth of a meter—really is. Ten hydrogen atoms in a row are one nanometer long. For perspective, consider that a sheet of paper is 75,000 nanometers thick. A red blood cell is 7,000 nanometers across. A typical virus is about 100 nanometers wide, and a [...]
Targeting medical treatment to an ailing body part is a practice as old as medicine itself. A Band-Aid is placed on a skinned knee. Drops go into itchy eyes. A broken arm goes into a cast. But often what ails us is inside the body and is not so easy to reach. In such [...]
The zealous immune response to injuries is known to cause paralyzing damage in spinal cord injury (SCI). Engineers have now created unique nanoparticles that redirect immune cells away from the spinal cord, promoting regeneration that helped restore spinal cord function in mice. The study was funded by the National Institute of Biomedical Imaging and [...]
