Scientists have discovered an elusive, mutated gene named for the Greek goddess, Aphrodite Kallipygos, that causes certain sheep to have unusually big and muscular bottoms. They hope the genetic mutation will illuminate how muscle and fat are deposited in these animals and possibly in humans.
The discovery is especially exciting, said the researchers, because the unusual gene has evaded all the traditional means of detection for nearly a decade. In fact, the gene appears to represent one of numerous stealth genes, called “imprinted,” that have yet to be discovered but which could produce a wide range of diseases.
Researchers from the U.S. Department of Agriculture and Duke University Medical Center discovered a gene called “callipyge,” (pronounced cal - ah - PEEJ) meaning “beautiful buttocks” in Greek, because the sheep have large, muscular bottoms with very little fat. Such an attribute could prove beneficial in breeding these sheep because it enables them to convert food into muscle 30 percent more efficiently than normal sheep. Moreover, the gene could explain specific processes that give rise to obesity and fat metabolism, said Randy Jirtle, Ph.D., professor of radiation oncology at Duke and co-author of the study.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
