By taking videos of a tiny beating zebrafish heart as it reconstructs its covering in a Petri dish, scientists have captured unexpected dynamics of cells involved in tissue regeneration. They found that the depleted heart tissue regenerates in a wave, led by a front of fast-moving, supersized cells and trailed by smaller cells that multiply to produce others. The nature of this wavefront is determined by mechanical tension on the cells.Full Story

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2023 budget of $9.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
