Mouse brain imaged from the microscopic to the macroscopic level

Researchers at the University of Chicago and the U.S. Department of Energy’s (DOE) Argonne National Laboratory have leveraged existing advanced X-ray microscopy techniques to bridge the gap between MRI (magnetic resonance imaging) and electron microscopy imaging, providing a viable pipeline for multiscale whole brain imaging within the same brain. The proof-of-concept demonstration involved imaging an entire mouse brain across five […]

Natural product isolated from sea sponge tested against cancer cells

Scientists from Far Eastern Federal University (FEFU) together with Russian and German colleagues, continue studying antitumor compounds synthesized based on bioactive molecules isolated from a sea sponge. One of them fights cancer cells resistant to standard chemotherapy, and at the same time has an interesting dual mechanism of action. A related article appears in Marine Drugs. Scientists have tested the […]
