This male fruit fly (Zaprionus vittiger) devoid of abdominal pigments illustrates the morphological diversity of abdominal pigmentation in Drosophilidae. Nicolas Gompel, postdoctoral fellow in molecular biology, researched the genes that drive differences in pigmentation in fruit flies (genus Drosophila), using this fly from a species stock center and other flies caught at his University Housing apartment and at the University Housing community garden compost heap.

How vastly different animals arrive at the same body plan or pattern of ornamentation has long been a conundrum of developmental biology.
But now, thanks to the colorful derriere of a wild fruit fly, captured on a compost heap by a University of Wisconsin-Madison post-doctoral student, scientists have been able to document a rare example of molecular convergence, the process by which different animals use the same genes to repeatedly invent similar body patterns and structures.
Writing in the current issue (Aug. 21) of the journal Nature, a group led by Sean Carroll and Nicolas Gompel of the Howard Hughes Medical Institute (HHMI) at UW-Madison, describes the genetic mechanisms that control the colors and patterns on fruit fly abdomens. The study suggests that the simple modulation of a transcription factor, a protein that can bind to DNA and influence its activity, may be responsible for governing the diversity of body color patterns among related animal species.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
