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 â programmable cells that can transform into ...
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 ...
Northwestern Medicine scientists have discovered that one of the body's most fundamental biological processesâhow red blood cells are madeâworks differently in humans than previously thought, ...
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 ...
Torie Bosch is the First Opinion editor at STAT. First Opinion is STATâs platform for interesting, illuminating, and provocative articles about the life sciences writ large, written by biotech ...
University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human developmentâincluding the production ...
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 - ...
