A microorganism whose evolutionary roots can be traced to the era of the first multicellular animals may provide a glimpse of how single-celled organisms made a critical evolutionary leap. In ...

Behavioral analysis can provide a lot of information about the health status or motivations of a living being. A new technology makes it possible for a single deep learning model to detect animal ...

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 ...

Animal models are established, important tools for preclinical safety and efficacy testing. Companies are advancing more “humanized” models to better reflect human responses, while at the same time ...

Rodents are arguably the most used animal models in biological research. However, scientists can employ alternative animal models, which often possess unique traits or adaptations, to improve their ...

Behavioral analysis can provide a lot of information about the health status or motivations of a living being. A new technology developed at EPFL makes it possible for a single deep learning model to ...

Advances in organ and computer models are raising the prospect that some animal experiments could be eliminated. But there ...

Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...
