EMBL Scientists Define Hierarchy of RNA Particle Assembly

In the fruit fly Drosophila, oskar mRNA, which is involved in defining the animal's body axes, is produced in the nuclei of nurse cells neighbouring the oocyte, and must be transported to the oocyte and along its entire length before being translated into protein.

Fluorescent Sensor Helping Scientists Track Specific Chromosomal Modifications

Chromosomal DNA is normally coiled and compacted via interactions with histone proteins to form material called chromatin. Chemical modification of the histones can profoundly alter how the chromatin is arranged, and this represents an important mechanism by which cells regulate gene expression.

Scientists Develop On-Off "Switch" that Paralyzes Animals

In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off "switch" that paralyzes animals when exposed to a beam of ultraviolet light. The animals stay paralyzed even when the light is turned off.
