Scientists Succeed in Growing New Bones Using Sound Waves

Using high-frequency sound waves, scientists at the Royal Melbourne Institute of Technology in Australia have managed to grow new bones out of stem cells. Having spent over a decade investigating how sound interacts with different materials, researchers developed a sound wave-generating device that can manipulate cells and fluids. “We can use the sound waves to apply just the right amount of pressure in the right …

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 …
