No one knows exactly how flatworms can rebuild their entire bodies from the tiniest sliver. Now, bioengineers and materials scientists are building new tools to study the worms’ awesome regenerative powers.

Karla Kirkegaard, Mark Krasnow and William Weis are now part of an organization created in 1863 to advise the nation on issues related to science and technology.

In preclinical trials, Stanford scientists and their collaborators harnessed the gene-editing system CRISPR-Cas9 to replace the mutated gene underpinning the devastating immune disease.

A Stanford-led study found that increasing the participation of older adults in colorectal cancer screening would help prevent more deaths than expanding testing to people in their 40s.

Stanford researchers have found a way to predict who will suffer heart problems from a common breast-cancer drug, as well as identified an FDA-approved medication that could mitigate those side effects.

An antibody to a protein on blood-forming stem cells may allow bone marrow transplants without the need for chemotherapy and radiation, according to a Stanford study.

Researchers’ experimental approach for preparing mice for blood stem cell transplantation may one day make it possible in humans to safely transplant organs or cells from any donor to any recipient.

Studying human oligodendrocytes, which provide insulation for nerve cells, has been challenging. But a new way of generating stem-cell-derived, three-dimensional brain-cell cultures is paying off.

The researchers found that by testing for fragments of cancer DNA in urine, they could find the cancer in early stages of development, when it’s easier to treat.

Stanford scientists have discovered a molecule that promotes the growth of collateral arteries in mice. The finding could open the door to developing therapies that help heal heart tissues damaged by disease or heart attack in humans.
