Two people were the first to receive the therapy for a condition that damages the spinal cord and optic nerve

China’s artificial embryos are part of an experiment to learn more about how human pregnancies could develop under microgravity conditions

The withdrawal after 22 years of a controversial stem cell paper highlights how perverse incentives can distort scientific progress

The bioengineered immune players called CAR T cells last longer and work better if pumped up with a large dose of a protein that makes them resemble stem cells

Researchers created a monkey that combines cells from two different individuals; a lab technique gave it a strange green glow

Recent news of complex embryo models revived debates over stem cells and human cloning. But biology says there’s nothing to worry about

To better understand early pregnancy loss without using actual human embryos, scientists employed stem cells to create models that mimic this stage of development

Recent research offers a tantalizing glimpse at a future in which two men can have biological children together, but any human applications remain far in the future

The risks associated with a bone marrow transplant used to treat HIV mean the procedure is unlikely to be widely used in its current form

Two research teams grew synthetic embryos using stem cells for long enough to see some organs develop
