Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Scientists have advanced human-animal chimera research by successfully growing human cells within the organs of mice. This development could bring experts closer to the goal of custom-growing human ...

Here’s what you’ll learn when you read this story: With more than 100,000 people in need of an organ transplant in the U.S. alone, scientists have turned toward perfecting human-animal chimeras as a ...

STANFORD, Calif. (KGO) -- In the Camarillo bioengineering lab at Stanford, engineers measure impacts both big and small. And that ability can help in research as far ranging as preventing concussions ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

For decades, scientists knew that male embryos in many mammal species—such as cows, mice, and even humans—tend to grow faster than female ones. But no one really knew why. The new study, published in ...
