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 ...

Methods like this can help scientists sort through potential drug candidates faster and with more biological detail.

Mitochondria—tiny structures that convert nutrients into energy—are often depicted as discrete kidney bean-shaped objects. But in reality, they form a dynamic, interconnected network throughout the ...

Every year, more than 100 million animals are used globally in biomedical research, yet over 90% of drugs that appear effective in animal trials fail during human clinical testing. 1 This staggering ...

In recent months, the Food and Drug Administration and National Institutes of Health have announced new initiatives to reduce and replace animal testing in biomedical research. Central to these ...

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A ...

Northwestern Medicine scientists have discovered that one of the body's most fundamental biological processes—how red blood cells are made—works differently in humans than previously thought, ...
