As any new mother knows, getting a baby to sleep at night is an art, and perhaps using snippets from Shakespeares Hamlet may help. But the science of how babies sleep – and what their processes may have in common with their adult counterparts – could be a small step closer to being better understood.
Sleep shows dramatic changes across early development. Quiet sleep (also known as non-rapid eye movement sleep [QS/NREMS]) increases in the course of the first year of life while active sleep or rapid eye movement sleep (AS/REMS) decreases. Slow wave sleep becomes predominant in the first part of the night beginning at about two months of age. In the last 30 years, researchers have increased their knowledge about the quantitative characteristics of the sleep EEG (electroencephalogram) during development, but how sleep regulation develops in early life was not a focus of their work. Accordingly, a new study of human infants has been conducted to document changes of the sleep EEG, with a particular focus on those facets that are markers of the sleep process in adults. The results suggest that EEG markers of sleep homeostasis appear in the first postnatal months and that sleep homeostasis goes through a period of maturation.

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...
