Despite a recent NIH announcement, animal models are becoming even more important because of recent breakthroughs in single-cell biology.

Using mathematical analysis of patterns of human and animal cell behavior, scientists say they have developed a computer program that mimics the behavior of such cells in any part of the body.

The Chan Zuckerberg Initiative unveils rBio, a groundbreaking AI model that simulates cell biology without lab experiments to accelerate drug discovery and disease research.

Today there are still logistical, ethical and legal limitations to using human embryos for research purposes, so scientists use alternative models including stem cell-based and animal models.
