Scientists Discover Structure of Gateways to Gene Control
This artist's illustration shows a portion of the genome. A long DNA molecule (red cord) is wrapped up into nucleosome structures with a histone-protein core (white spheres). The gateway to gene transcription spans the control switch (coils) on the left nucleosome to the beginning of the gene (green arrow) on the right nucleosome." Credit: Christina Ullman
Gamma-Ray Birth Cries Suggest Massive Magnetic Engines
The core of a massive star in a distant galaxy collapses, ending its life — though there is little effect visible at the surface. Deep inside, twin beams of matter and energy begin to blast their way outward. (Image Credit: NASA/Swift/Sonoma State University/A. Simonnet)
Discovery Reveals that Distant Quasars Live in Massive Dark-Matter Halos

High-Quality Helium Crystals Show Supersolid Behavior
New Protein Super-Family Discovered with Functions Critical for Animal Life
The DANGER family member, DANGER1A, is expressed in a variety of cells (brown color) which lose their ability to divide including nerves, muscle, and neuroendocrine cells. DANGER1A is first expressed in the developing mouse (embryonic stage 13.5) in the spinal cord (arrows), with increasing expression in post-natal day 0 mice, and is maximal in the adult mouse brain.

Researchers Discover Master Metabolism Regulator with Links to Obesity, Heart Disease, and Malnutrition
Normal mice fed a diet deficient in leucine do not accumulate fat in their liver (left panel) whereas mutant mice that lack the GCN2 enzyme develop a massive accumulation of fat (severe hepatic steatosis), as seen in the right panel (red droplets). Credit: Douglas Cavener lab, Penn State
Microprinting Technique for Patterning Single Molecules
