Materials Scientist Seeks Dwarfism Clues in a Cell’s Membrane

Johns Hopkins University

A common form of dwarfism is caused by a single genetic mutation. If a scientist could figure out precisely how this errant protein causes trouble, then a way to prevent the condition might be found. Sounds like a job for a biologist. But what about an engineer?

RNA Snippets Control Protein Production by Disabling mRNAs

Whitehead Institute for Biomedical Research

Short pieces of RNA, called microRNAs, control protein production primarily by causing the proteins’ RNA templates (known as messenger RNA or mRNA) to be disabled by the cell, according to Whitehead Institute scientists.
