Scientists Build Robotic Fish Using Human Heart Cells

Recently a team of scientists built a school of robotic fish powered by human heart cells—a project that attempts to understand how to construct replacement hearts for those with cardiovascular diseases. The biohybrid fish—made from paper, plastic, gelatin and two strips of living heart muscle cells—can swim entirely on their own for more than three months, as movement causes the strips of cells to contract, …

Experimental Nuclear Fusion Reactor Proves Limitless, Clean Power Is Possible

Curbing climate change means finding a near-limitless, zero-carbon power source. To do that scientists have often turned to nuclear fusion—the process of fusing two or more atoms together, which releases massive amounts of energy (and is also the process that makes the sun and stars shine). But while scientists have been able to generate this energy before, they haven’t been able to sustain it for …

Scientists Globally Map Coral Reefs For The First Time

Under the direction of Arizona State University’s Center for Global Discovery and Conservation, more than 450 teams of scientists have succeeded in creating the first continually updating map of the world’s shallow coral reefs, an undertaking that required 2.25 million satellite images and about 100,000 square miles. As one of the most biodiverse ecosystems on the planet, coral reefs are an important home for marine …
