One heat shock protein affects the expression of many complex traits genes, which may contribute to rapid evolutionary change.

A long, fibrous coil grown by a single-cell protozoan is far more powerful for its weight than a car engine.

Your immune system is an army on full alert. How does it recognize the enemy when it's under attack?

Molecular biologist Hidde Ploegh has just been appointed to the faculty of Whitehead Institute for Biomedical Research.

Tighter visa restrictions are making it harder for foreign researchers to work in the United States. What's the effect on science—and scientists?

Using yeast as a testing ground, Whitehead researchers have for the first time revealed all the “controlling elements” of an entire genome—findings that may soon contribute to a new way of understanding human health and disease.

The same characteristics that make misfolded proteins known as prions such a pernicious medical threat in neurodegenerative diseases may offer a construction toolkit for manufacturing nanoscale electrical circuits, researchers report this week in the online edition of the Proceedings of the National Academy of Sciences.

Susan L. Lindquist, director of the Whitehead Institute for Biomedical Research, is best known for ground-breaking work on how such diverse processes as stress tolerance, neurodegenerative disease, and heredity can be governed by changes in protein conformation.
