The simple, constant rhythm of a beating heart is a reassuring sign of life. With each lub-dub, blood brings life-sustaining oxygen throughout the body. But behind this steady beat is a busy ...

Researchers have been using organoids - 3D organ-like, tightly-packed cell cultures - as models to study organ development, disease and drug discovery with excellent success. However, most existing ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Tucked in the basement of the Mayo Building on the University of Minnesota’s Twin Cities campus sits a detached, beating pig’s heart floating in clear liquid. Graduate and undergraduate students ...

Scientists have built a school of robotic fish powered by human heart cells. The fish, which swim on their own, show how lab-grown heart tissue can be designed to maintain a rhythmic beat indefinitely ...

The term cyborg conjures up images from Star Trek, RoboCop, and even The Six Million Dollar Man, and while we might get there someday, our first attempts at creating biohybrids are a lot simpler, but ...

A study on the bioartificial heart component titled "Toward Hierarchical Assembly of Aligned Cell Sheets into a Conical Cardiac Ventricle Using Microfabricated Elastomers" has been published in the ...

Miniature-sized heart chambers called ventricles have been 3D printed with live human heart muscle cells and shown to beat on their own for at least three months. Artificial heart tissue can be made ...

Researchers have reported growing hearts containing human cells in pig embryos for the first time. The embryos survived for 21 days, and in that time their tiny hearts started beating. The findings ...

The pink, white and red blob of tissue quivers in a vat of clear goop about the size of a kitchen sink. Graduate students whiz around this slimy beating heart and crawl under the tubes connected to ...

Have you ever paused to wonder how many times your heart has beaten since birth? This incredible organ works tirelessly, ...
