Researchers develop new imaging technique for studying nanoscale coronavirus-host interactions

Lei S. Qi of Stanford University, California, and colleagues published research showing a potential framework to better characterize coronaviruses' biology. While most high-resolution imaging techniques show the life cycle of coronaviruses, identifying viral or host proteins and genomes remains poorly understood. Their results use multi-color super-resolution imaging allows them to study nanoscopic parts of the coronavirus, including RNA.

Researchers use new technique to visualize brain tissue noninvasively

The way the human brain works remains, to a great extent, a topic of controversy. One reason is our limited ability to study neuronal processes at the level of single cells and capillaries across the entire living brain without employing highly invasive surgical methods. This limitation is now on the brink of change.

New implantable tool images brain activity in 3D

Tools that allow neuroscientists to record and quantify functional activity within the living brain are in great demand. Traditionally, researchers have used techniques such as functional magnetic resonance imaging, but this method cannot record neural activity with high spatial resolution or in moving subjects.
