Bioprinting complex living tissue in just a few seconds

Tissue engineers create artificial organs and tissues that can be used to develop and test new drugs, repair damaged tissue and even replace entire organs in the human body. However, current fabrication methods limit their ...

New hydrogels show promise in treating bone defects

Bioengineers and dentists from the UCLA School of Dentistry have developed a new hydrogel that is more porous and effective in promoting tissue repair and regeneration compared to hydrogels that are currently available. Once ...

From the tiny testes of flies, new insight into how genes arise

In the battle of the sexes, males appear to have the innovative edge—from a genetic standpoint, at least. Scientists are finding that the testes are more than mere factories for sperm; these organs also serve as hotspots ...

New nanotechnology could aid stem cell transplantation research

Nanotechnology developed at Rutgers University-New Brunswick could boost research on stem cell transplantation, which may help people with Alzheimer's disease, Parkinson's disease, other neurodegenerative diseases and central ...

Bacteria made to mimic cells, form communities

Rice University scientists have found a way to engineer a new kind of cell differentiation in bacteria, inspired by a naturally occurring process in stem cells.

Cyborg organoids offer rare view into early stages of development

What happens in the early days of organ development? How do a small group of cells organize to become a heart, a brain, or a kidney? This critical period of development has long remained the black box of developmental biology, ...

Visa concerns deter foreign-born PhDs from working in startups

Foreign-born Ph.D. graduates with science and engineering degrees from American universities apply to and receive offers for technology startup jobs at the same rate as U.S. citizens, but are only half as likely to actually ...

Space station cell study seeks causes of major diseases

High above the Earth, researchers are conducting a first-of-its-kind study to help patients with Parkinson's disease and multiple sclerosis on the planet below. The International Space Station experiment is looking for what ...
