Yeast’s variety show

February 11, 2004

New research into a family of cell wall proteins shows how yeast can present a variety of “faces” to its environment. In pathogens like yeast, these cell surface proteins regulate how the cell sticks to other cells, interacts with surrounding tissue and evades detection by the immune system.

Whitehead Director elected to Johnson & Johnson Board of Directors

February 5, 2004

Susan Lindquist, director of Whitehead Institute for Biomedical Research and a professor of biology at Massachusetts Institute of Technology, has been elected to the Board of Directors of Johnson & Johnson.

Gene that produces 38,000 different proteins involved in cellular identification

February 2, 2004

A single gene that codes for more than 38,000 different proteins may allow individual cells in the brain to distinguish themselves from other cells, says Andrew Chess, a scientist at Whitehead Institute and lead author of the study, which appears online this week in the journal Nature Genetics.

Whitehead scientist named president of Genetics Society of America

January 28, 2004

Whitehead Member Terry Orr-Weaver has been elected president of the Genetics Society of America, a nonprofit scientific organization whose members specialize in genetic studies.

New method identifies human microRNA targets

January 28, 2004

Research into the mechanics of microRNAs, tiny molecules that can selectively silence genes, has revealed a new mode of gene regulation that scientists believe has a broad impact on both plant and animal cells.

Robert Weinberg awarded 2004 Wolf Prize in Medicine

January 14, 2004

Minister of Education, Culture and Sport, Limor Livnat, chairperson of the Wolf Foundation Council, announced that the 2004 Wolf Prize in Medicine, in the amount of $100,000, was jointly awarded to Whitehead founding Member Robert Weinberg.

“Mad Cow” Mechanism May Be Integral to Storing Memory

December 24, 2003

Scientists have discovered a new process for how memories might be stored, a finding that could help explain one of the least-understood activities of the brain.

The Protein Universe

December 16, 2003

The story of life and all its associated processes takes place within a vast universe of proteins and their interactions, a bountiful frontier ripe for exploration.

Study Identifies Protein Complex Critical in Rapid Embryogenesis

December 11, 2003

For scientists who study embryonic development, insects, amphibians and marine invertebrates provide a unique window on the early stages of an embryo’s life. These organisms differ from higher life forms by having a simpler system for cell division, but it’s a system on fast forward: The embryos receive a maternal care package that permits their DNA replication and chromosome segregation to go into overdrive.

Robert Langer Appointed to Whitehead Institute Board of Directors

December 9, 2003

Robert Langer, the Kenneth J. Germeshausen professor of chemical and biomedical engineering at MIT, is a pioneer in biomedical engineering and author of more than 500 issued and pending patents. His research on drug delivery and tissue engineering serves as a foundation for today's $20 billion drug-delivery industry.

MicroRNAs Play a Role in Blood Formation, Study Finds

December 4, 2003

Scientists have been fascinated by miRNAs ever since the abundance of these tiny RNAs was discovered in 2001. Rather than code for proteins, miRNAs serve as regulators that turn protein-coding genes off. Now, new studies by scientists at Whitehead Institute for Biomedical Research are offering insight into the role miRNAs play in mammalian development.

Yeast Helps Researchers Better Understand Parkinson's Mystery

December 4, 2003

Scientists know that in patients with Parkinson’s disease, certain proteins in the brain form clusters that somehow contribute to cell death and, eventually, lead to the onset of the disease’s debilitating symptoms. Whitehead scientists have succeeded in duplicating the disease’s most critical features in the most readily manipulated model organism in existence.
