DNA ‘barcodes’ help researchers track rise, fall of yeast dynasties
A technique developed by Stanford researchers has implications for understanding how cancer cells evolve as a tumor grows or how a virus spreads and changes during an infection.
Small molecule might help reduce cancer in at-risk population, study finds
Scientists have shown that small molecules can “hijack” enzyme function in mice, suggesting a possible preventive mechanism for alcohol-related cancers in an at-risk population.
Customized DNA rings aid early cancer detection in mice, study finds
Tiny DNA rings, carrying instructions for making a blood-detectable biomarker, can enter both healthy cells and cancer cells. But only cancer cells follow the recipe to make the biomarker.
Stanford Medicine magazine reports on intersection of time, health
The spring issue features a theme package on the clocks that rule our bodies, as well as an excerpt from a new biography of Nobel Prize-winning biochemist Paul Berg, PhD, and a report on the high-risk birth of a set of triplets.
Discrimination fears remain for LGBT medical students, study finds
A survey has found that about 30 percent of sexual minority medical students hide or don’t reveal their sexual and gender identity, often because they fear discrimination…
Project maps human epigenome, discovers immune system role in Alzheimer’s
The epigenome controls gene expression across diverse cell types, and integrates genetic and environmental signals. A new reference map will help interpret the genetic basis for disease.
Tiny fish makes big splash in aging research at Stanford
Researchers disabled aging-associated genes in the short-lived African killifish, including one for an enzyme called telomerase, whose absence caused humanlike disease in the animal.
Growing number of donor hearts rejected while need for transplants rises, study finds
A new study has found that improving scientific guidelines to determine whether a donor heart is acceptable for transplant could help save the lives of patients with deadly heart disease.
Different mental disorders linked to same brain-matter loss, study finds
A meta-analysis of 193 brain-imaging studies shows similar gray-matter loss in the brains of people with diagnoses as different as schizophrenia, depression and addiction.
Study ties immune cells to delayed onset of post-stroke dementia
Researchers say that the appearance in the brain of a type of immune cell has been implicated in delayed dementia in mice and humans who have suffered a stroke.
Leading the Biomedical Revolution
We are in the middle of a biomedical revolution more profound and far-reaching than the industrial and digital revolutions that made it possible.
A Legacy of Innovation
Stanford Medicine's unrivaled atmosphere of breakthrough thinking and interdisciplinary collaboration has fueled a long history of achievements.
