Tarsiers are indigenous to the islands of Southeast Asia, but visitors to the zoo should also be familiar with these charming monkeys with their conspicuously big eyes. A meeting with them in the monkey house is practically a visit with our own relatives, a new study now shows.
For decades, we remained in the dark regarding the evolutionary origin of the tarsiers, but now a new scientific study has brought light into this dark corner of our knowledge; the tarsiers, or Ghost Monkeys, are indisputably much more closely related to humans and other higher primates than previously imagined. The research group of Dr. Jürgen Schmitz in the Institute of Experimental Pathology at the University of Münster in Germany, funded by the German Science Foundation (DFG), has finally resolved the controversial question of the phylogenetic decent and evolutionary history of this branch of higher primates. The results of their scientific analyses have just been published online in the journal "Nature Scientific Reports".The tarsiers were long thought to represent the very first branching on the evolutionary tree of primates, and thus more distantly related to humans and other higher primates. But this view was already shaken in 2001, when Dr. Jürgen Schmitz and his colleagues identified 50-million-year-old so called ‘Jumping genes’ in the current genomes of tarsiers. “These jumping genes are contemporary, quasi fossilized genomic witnesses of tarsiers much closer relationship to humans than to other prosimians,” explained Schmitz. Unfortunately, over the next twelve years, others’ analyses of tarsier DNA sequences could not definitively confirm their placement on this branch of the evolutionary tree of primates – until now.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
