(Phys.org)—Given that blood supply to the brain and spinal cord is fundamental to central nervous system (CNS) physiology and pathology, it's not surprising that trauma and disease in spinal cord blood vessels and neurons ...
(Phys.org)—A widely-used tool for studying cellular structure – indeed, a technique in use throughout biology – phase contrast microscopy converts optical phase shifts to changes in brightness. At the same time, several ...
Noninvasive inspection of layered structures is challenging for time-resolved imaging methods, where the resolution and contrast can be compromised by prominent signal attenuation with interlayer reflections and dispersions.
Researchers Jayne Spiller and Camilla Gilmore at the Center for Mathematical Cognition, University of Loughborough, U.K., have investigated the intersection of sleep and mathematical memory, finding that sleep after learning ...
Superconductors are the key to lossless current flow. However, the realization of superconducting diodes has only recently become an important topic of fundamental research. An international research team involving the theoretical ...

(Phys.org)—A new type of nanoparticle-based MRI contrast agent demonstrates selectivity for tumor cells over non-cancerous cells, can detect hypoxia, and is sensitive enough allow for the detection of difficult-to-find ...
(Phys.org) —Nano-sized crystals of magnetic material can be found in a wide variety of organisms. Among the most studied are magnetotactic bacteria, which can orient and navigate using biosynthesized magnetosomes. These ...
(PhysOrg.com) -- Researchers in Taiwan have developed a new imaging contrast agent that will enable cancer patients to undergo CT and MRI scans on the same day, cutting diagnosis time in half.
Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University ...
