Northwestern Medicine scientists have discovered that one of the body's most fundamental biological processes—how red blood ...

LaBonne is president of the Society for Developmental Biology and the Erastus Otis Haven professor of molecular biosciences at Northwestern University. Imagine a world without lifesaving medicines, ...

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 ...

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 ...

Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining ...

Animals, from worms and sponges to jellyfish and whales, contain anywhere from a few thousand to tens of trillions of nearly genetically identical cells. Depending on the organism, these cells arrange ...

As a researcher, I still remember the discomfort I felt every time I had to sacrifice laboratory animals for an experiment. For decades, animals like mice, rats and pigs have been essential tools in ...

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 - ...

This fluorescence image shows chloroplasts (magenta colored) successfully incorporated into the hamster cells, with other features of the animal cell also highlighted (nuclei in light blue and ...
