Analyzing the Cell Division in Stem Cells

What appears to be a simple task for a cell—splitting in two—is indeed a complex series of engineering puzzles. To produce two working cells, a splitting cell has to maneuver its interiors in such a way that the appropriate components will end up in each cell.

A Rapid Method for the Quantitative Detection of miRNA

Researchers investigating the growth of a roundworm discovered a tiny RNA molecule that controlled the expression of specific genes in the early 1990s. This resulted in the discovery of microRNAs (miRNAs), which are now known to exist in all forms of life. These molecules, it turns out, play vital functions in a variety of biological processes.

Using Cellular Reprogramming to Make the Heart Function Like New Again

A recent study using mice has revealed a way to turn back the clock after heart attack. The researchers behind the work used RNAs to instruct cells in an injured heart to eliminate scar tissue and recreate cardiac muscle, allowing the heart to function like new again.

Entry of Aging-Associated Enzymes into Human Genetic Material

An enzyme that controls aging and other metabolic processes accesses human genetic material to modify gene expression within the cell, according to a new study. Images of a sirtuin enzyme bound to a nucleosome, a tightly packed complex of DNA and proteins called histones, have been created by a team led by Penn State researchers.
