A common trope in science fiction, especially cyberpunk fiction, involves custom-grown replacement organs based on the recipient's own flesh. We're not there yet as a species—and in fact still a good ...

For years, scientists have been able to print living tissue. The problem is that most of it looks more like a sparse sketch than a real organ. In the human body, cells are packed tightly together, ...

3D bioprinting, in which living tissues are printed with cells mixed into soft hydrogels, or "bio-inks," is widely used in the field of bioengineering for modeling or replacing the tissues in our ...

Andy Altman covered all things science and tech. He led production on CNET's award-winning limited documentary series Hacking the Apocalypse. He also created and co-hosted our video series What the ...

It's an achievement with important implications for scientists studying the brain and working on treatments for a broad range of neurological and neurodevelopmental disorders, such as Alzheimer's and ...

In February we ran a story on the first 3D-printed human stem cells. The article described printing whole cells in droplet form, which then aggregate into small spheroids of tissue. The fact that ...

A flat sheet of living cells, no thicker than a few layers, sits in a dish. Within hours, it begins to curl, crease, and fold into a tube, guided not by any external force but by the mechanical pull ...

We’ve come a long way from the Vacanti mouse. Back in the mid-90s, Charles Vacanti and other researchers experimented with cartilage regeneration and, with the help of a biodegradable mold and bovine ...

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle remains: real muscle is not just a mass of cells. Its strength and function ...

They hope their research could open the doors for the development of treatments for existing neurological disorders, including Alzheimer’s and Parkinson’s disease. As detailed in a new paper published ...
