Tiny, robotic fish powered by human heart cells suggest that scientists are getting closer to their goal of building replacement hearts from living tissue.

The National Cancer Act became law 50 years ago. Cancer went from shameful taboo to one of the best-funded areas of medicine. Much of the credit for this transformation goes to one woman, Mary Lasker.

Coronavirus researchers need the right genetically engineered mice to test potential vaccines. But most of these mice have been on ice. One lab is breeding a new generation of mice to meet the demand.

Black scientists more often seek grants for community health studies, but molecular-level research proposals win more funding. More diversity throughout the process could help close the gap, says NIH.

Scientists hoping to get more diversity of ancestry among medical research volunteers need to grapple with the history of medical exploitation, says a Columbia University bioethicist.

Scientists and statisticians are putting forth a bold idea: ban the very concept of "statistical significance." A bit more humility would be in order to account for the ambiguity in the world.

An international group of 18 prominent scientists and bioethicists is calling for countries around the world to impose a moratorium on the creation of babies whose genes have been altered in the lab.

A study found parachutes were no more effective than backpacks in preventing harm to people jumping from aircraft. The researchers' tongue-in-cheek experiment makes a deeper point about science.

To protect a developing fetus from experimental drugs or treatments that might cause birth defects, pregnant women aren't included in many clinical trials. But that limits the safety evidence, too.

In a quest to rapidly advance its scientific depth and breadth, China is recruiting scientists from around the world. Some from the U.S. say the greater funding for school and research is freeing.

A working group convened by the National Institutes of Health looked at where chimps that had been used in research should live now. Unless relocating chimps would endanger them, a sanctuary is best.

If a female researcher asks a man if he's in pain, he's less likely to admit it. The effect of gender on study results has been known for years. But it's rarely disclosed or discussed.
