Imaging method reveals a “symphony of cellular activities”
Within a single cell, thousands of molecules, such as proteins, ions, and other signaling molecules, work together to perform all kinds of functions —...
Memories create ‘fingerprints’ that reveal how the brain is organized
While the broad architecture and organization of the human brain is universal, new research shows how the differences between how people reimagine common scenarios...
Seeing depression in the pupil
When people win or lose something, their pupils dilate slightly. Researchers have found that this dilation is less pronounced in acutely depressed patients than...
Researchers examine which approaches are most effective at reducing COVID-19 spread
Simon Fraser University professors Paul Tupper and Caroline Colijn have found that physical distancing is universally effective at reducing the spread of COVID-19, while...
Commonly used antibiotic shows promise for combating Zika infections
In 2015, hundreds of children were born with brain deformities resulting from a global outbreak of Zika virus infections. Recently, National Institutes of Health...
