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 ...

People have always looked for patterns to explain the universe and to predict the future. “Red sky at night, sailor’s delight. Red sky in morning, sailor’s warning” is an adage predicting the weather.

Since the ISSCR released its May 2021 update to the Guidelines for Stem Cell Research and Clinical Translation, research with stem cell-based embryo models has evolved rapidly. During the extensive ...

Researchers have crossed a threshold that once belonged squarely to science fiction: they have built working models of brains, both in silicon and in living tissue, that can learn, adapt, and even ...

The International Society for Stem Cell Research (ISSCR) Embryo Models Working Group has released updated recommendations for the oversight and regulation of stem cell-based embryo models (SCBEM), ...

In July, researchers in the United Kingdom published a code of practice on how human stem cells should be used to mimic embryo development in the laboratory. This code was produced by a working ...

Animal models have long shaped how biomedical research is conducted. They have influenced how diseases are studied, how ...

You’ve probably seen an artificial intelligence system go off track. You ask for a video of a dog, and as the dog runs behind the love seat, its collar disappears. Then, as the camera pans back, the ...

Physics dazzled Miles Cranmer from an early age. His grandfather, a physics professor at the University of Toronto, gave him books on the subject, and his parents took him to open houses at ...

Mathematics is traditionally a solitary science. In 1986 Andrew Wiles withdrew to his study for seven years to prove Fermat’s theorem. The resulting proofs are often difficult for colleagues to ...
