While picking apart the genetic makeup of the plant Arabidopsis, two Dartmouth researchers made a startling discovery. They found that approximately 36 percent of its genome is potentially regulated by the circadian clock, which is three and a half times more than had previously been estimated.
The study, which appears in the June issue of Plant Physiology, was conducted by C. Robertson McClung, Dartmouth professor of biological sciences, and Todd Michael, a former Dartmouth graduate student who is now a postdoctoral fellow at the Salk Institute in La Jolla, Calif. Their research on circadian-controlled genes contributes to efforts to help improve plant productivity and can possibly lead to growing crops that are more resistant to stressful soil or climate conditions.
McClung and Michael used a technique called "gene trapping" or "enhancer trapping" to measure how much mRNA is produced or synthesized by large sections in the genome. According to McClung, a great deal of gene regulation occurs in the genes ability to synthesize mRNA, which then is translated into proteins that perform the critical metabolic activities of a cell.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
