New Research into the Mechanisms of Gene Regulation
The team of scientists used red blood cells from a mouse to study the mechanisms of gene regulation. The research is expected to help in the development of new therapies to treat people who suffer from sickle-cell anemia and other blood disorders. Credit: Wikipedia Commons (Public Domain)
Rare Space Experiment Gives Clues About the Fundamental Structure of the Universe
In this illustration, one photon (purple) carries a million times the energy of another (yellow). Some theorists predict travel delays for higher-energy photons, which interact more strongly with the proposed frothy nature of space-time. Yet Fermi data on two photons from a gamma-ray burst fail to show this effect, eliminating some approaches to a new theory of gravity. Credit: NASA/Sanoma State University/Aurore Simonnet

The cartridge holds a "plug-plate" at the top, which positions a thousand optical fibers (red and blue). These cartridges are locked into the base of the telescope and are changed many times during a night.
Turning Up the Voltage Stops Opposites from Attracting, Study Finds
The scientists performed the same experiment in a number of different situations, using both everyday and/or industrially important liquids. Credit W. D. Ristenpart, J. C. Bird, and A. Belmonte.
