Peter W. Atkinson, a University of California, Riverside professor of entomology and member of the university’s Institute for Integrative Genome Biology, is part of a team that has linked the movement of small pieces of DNA, known as transposable elements, to a process called V(D)J recombination that produces the genetic diversity responsible for the production of antibodies. This will help scientists understand the mixing and matching of DNA in organisms and the role this mixing plays in healthy and diseased cells.
Nancy L. Craig from the Howard Hughes Medical Institute and Department of Molecular Biology & Genetics at Johns Hopkins Medical Institute led the team, which published its findings in this week’s issue of the journal Nature, in a paper titled Transposition of hAT elements links transposable elements and V(D)J recombination. Also on the team were Liqin Zhou and Rupak Mitra from Johns Hopkins, and Alison Burgess Hickman and Fred Dyda from the Laboratory of Molecular Biology at the National Institute of Diabetes and Digestive and Kidney Diseases, Bethesda, Md.
“These functional and comparative studies link the movement of transposable elements and V(D)J recombination. This outcome has implications for understanding transposable element movement in all organisms as well as the role that transpositional type recombination mechanisms have in chromosomal rearrangements of both healthy and diseased cells,” Atkinson said. “Of growing interest is the role that some of these rearrangements may play in the genesis of some cancers.”

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
