Credit: POSTECH Newly developed photoacoustic microscopy uses vibrations generated when light is absorbed and captures images of cells or blood vessels. This development has increased the possibility of peering inside the body without contrast agents. However, obtaining...

Credit: Shutterstock A team from UNSW’s Kirby Institute and St Vincent’s Hospital Sydney have uncovered an immune profile for long COVID, potentially paving the way for tailored treatment for those with ongoing...
Scientists at the University of Bonn identify previously unknown disease mechanism UNIVERSITY OF BONN DEOXYSPHINGOLIPIDS (GREEN) INTERFERE NOT ONLY WITH THE WORK OF THE MITOCHONDRIA (RED) BUT ALSO WITH CELL DIVISION. SOME OF THEM THEREFORE HAVE TWO NUCLEI (TURQUOISE). view more CREDIT: © AG KÜRSCHNER/UNIVERSITÄT BONN A congenital disorder of the fat metabolism can apparently...
by Marilynn Marchione This electron microscope image made available and color-enhanced by the National Institute of Allergy and Infectious Diseases Integrated Research Facility in Fort Detrick, Md., shows Novel Coronavirus SARS-CoV-2 virus particles, orange, isolated from a patient. University of Hong Kong scientists claim to have the first evidence of someone being reinfected with the...
Silky material uses magnetic particles to regrow bone By Ben Coxworth August 10, 2020 It was just a couple of months ago that we heard about an implantable material that electrically stimulates bone cells, causing them to reproduce. Now, scientists have created a similar substance that utilizes magnetism. There are already a number of experimental...
Electrical stimulation and chemical pharmaceuticals are the two ways that doctors and scientists routinely use to manipulate neural cells. Chemicals have their side effects, are slow to take effect, and are usually systemically delivered, while electrical stimulation usually requires invasive wires, is limited in its resolution, and is nearly impossible to administer within certain parts...
A new technique could help reduce antibiotic prescribing by predicting which drugs could be effective in fighting bacteria within minutes. Scientists at the University of Exeter have developed the method, which allows users to see whether a bacterium is likely to respond to antibiotics. The research is currently in early stages of development, and the...
by Beckman Institute for Advanced Science and Technology Researchers at the GSK Center for Optical Molecular Imaging have developed a new microscope that looks at the different parameters that change during wound healing. They hope to use this technique to understand how skin disorders, such as foot ulcers in diabetic patients and psoriasis, can be...
GERMAN CANCER RESEARCH CENTER (DEUTSCHES KREBSFORSCHUNGSZENTRUM, DKFZ) Chimeric antigen receptor (CAR) T cell therapy is a new and in some cases highly effective form of immunotherapy to treat certain types of cancer of the blood and lymph system. This promising treatment comes at a cost, however: The manufacturers charge up to EUR 320,000 for the...
