Scientists Develop a Technology That Reverses Hearing Loss

Founded by MIT scientists, the clinical-stage biotech company Frequency Therapeutics discovered a way to reverse hearing loss without hearing aids or implants. Focusing on progenitor cells (which reside in the inner ear and turn into hair cells when humans are in utero, before going dormant) the company injects small molecules into the cochlea, which transform these cells into hair cells that help us hear. During …

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 …

World’s First Living Robots Can Now Reproduce

Last year, researchers in the US created the world’s first living machine, called xenobots. Composed of bundles of stem cells from the African clawed frog (xenopus laevis), the new life form was programmed to accomplish tasks and move microscopic objects around. Now, they can reproduce. “One [xenobot] parent can begin a pile and then, by chance, a second parent can push more cells into that …
