Mutations at the heart of drug-resistant HIV
A multicenter study has found that a small group of mutations accounted for a majority of the cases of transmission-related resistance to HIV drugs used to treat infections in developing countries…
Scientists tackle surprise poliovirus
A newly recognized form of poliovirus has emerged from one of the vaccines being used to eradicate the paralyzing illness. Stanford’s Yvonne Maldonado and others are studying how to solve the problem.
Studying X chromosome inactivation
Many proteins interact with an RNA molecule called Xist to coat and silence one X chromosome in every female cell. Learning how genes are targeted and silenced may help researchers studying sex-specific diseases.
Vision & Leadership
A leader in the biomedical revolution, Stanford Medicine advances the health of adults and children through the integrated clinical, research and training missions of Stanford University School of Medicine, Stanford Health Care and Stanford Children's Health.

First synthesis of biologically active DNA in test tube
Nobel laureate Arthur Kornberg creates a strand of biologically active DNA, paving the way for studies of genetics.
First adult human heart transplant in the United States
Norman Shumway successfully transplants a heart into 54-year-old steelworker Mike Kasperak, who survives for 14 days.
First expression of a foreign gene implanted in bacteria by recombinant DNA methods
Geneticist Stanely Cohen transfers a foreign gene into bacterial cells, which then express the gene.
First successful human combined heart/lung transplant in the world (fourth attempted worldwide)
Mary Gohlke receives the world's first combined heart and lung transplant in a landmark operation led by surgeon Bruce Reitz.
Isolation of pure hematopoietic stem cells from mice
Pathologist Irving Weissman isolates a rare mouse cell, known as the hematopoetic stem cell, which gives rise to all the cells of the blood and immune systems.
First use of gene expression profiling to predict cancer outcomes
Application and expansion of optogenetics, a technique to control brain cell activity with light
Bioengineer Karl Deisseroth and his team develop a technique known as optogenetics that allows them to genetically alter brain cell activity in mice with light.
