Once believed to be unique to birds and mammals, sleep is found across the metazoan kingdom. Some animals, it seems, can’t live without it, though no one knows exactly why.
The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.
Date: July 5, 1999Table of Cell Signaling Tools At today's research pace, new signaling mechanisms within and between cells are emerging not one by one but in a chain reaction. Each new discovery has strong implications for previously established models, sometimes overturning several assumptions at once. With such a large number of interacting systems--from cell adhesion to differentiation and apoptosis--and receptor pathways, keeping up with the wealth of cell-signaling research tools can be l
