The venous system maintains the health of our brains by removing deoxygenated blood and other waste products, but its complexity and variability have made scientific study difficult. Now, a UC ...

(Allen Institute Photo) Researchers say they’ve accomplished a feat that was said to be impossible 46 years ago: mapping the cells in a cubic millimeter of brain tissue and tracing their activity.

This study uses a forward solution based on ray-tracing modeling specifically designed for illumination ... along the diameter axis at near-offset range, but not at the almost contact internal ...

These include proximity and contact tracing, symptom monitoring ... ethical and legal challenges for researchers and policy makers. Figure 2 Sunburst diagram mapping the ethical and legal issues ...

Contact-tracing apps like SwissCovid have enormous potential to mitigate the spread of the COVID-19 pandemic. Users allow the apps to track their contact with each other and estimate the chances ...

But it hasn’t seemed to bring back discussions of contact tracing, one of the first best hopes for containing the pandemic in its earliest days. What media attention it has received of late has ...

Background: Contact tracing is a core element of the public health response ... We calculated yield indicators as stepwise and cumulative proportions and presented them using flow diagrams and a ...

New research suggests that officials should prioritize contact tracing and quarantine. The emergence of the delta variant and continued vaccine hesitancy have caused many health and government ...

A 3-D reconstruction of cells from the MICrONS data set shows the complexity of shapes and branching axons and dendrites in a mouse brain. Each cell is labeled with a different color. (MICrONS ...
