Researchers at The University of Texas at Austin recently received support from the National Science Foundation (NSF) to ...

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 ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Formation of the energy-producing machinery in the proximal tubule of the nephron is an essential step in differentiation. The authors show that mitochondrial localization depends on LRRK2, the ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...

For decades, animal models have been the gold standard for preclinical testing of potential drugs. Yet, even the best animal models are not perfect. For example, small rodent species with engrafted ...

Liver disease is a major global health problem, causing over two million deaths worldwide each year. While animal models have ...

Artificial intelligence has traditionally advanced through automatic accuracy tests in tasks meant to approximate human knowledge. Carefully crafted benchmark tests such as The General Language ...
