By exposing rats to novel objects and measuring their brain signals, Duke University researchers have detected telltale signal reverberations in wide areas of the brain during sleep that reveal the process of consolidating memories. According to the researchers, their findings offer important evidence that extensive regions of the brain are involved in processing memories during a particular form of sleep, called slow-wave sleep.
The researchers said their findings lay to rest previous doubts that sleep enables consolidation of newly acquired memories, and also establishes roles for both slow-wave sleep and rapid eye movement (REM) sleep in memory consolidation. Slow-wave sleep is a deep dreamless sleep, and REM sleep is associated with dreaming.
The researchers published their findings on Jan. 19, 2004, in the online Public Library of Science (www.plos.org). Senior author on the paper was Miguel Nicolelis, Ph.D., a professor of neurobiology and of biomedical engineering, who is also co-director of the Duke Center for Neuroengineering. Lead author was Sidarta Ribeiro, Ph.D., in Nicoleliss laboratory. Other co authors were neurobiologists Damien Gervasoni, Ph.D., Ernesto Soares, Yi Zhou, Shih-Chieh Lin, M.D., and Janaina Pantoja; and Michael Lavine, Ph.D., of the Duke Institute of Statistics and Decision Sciences. Their work was supported by the National Institutes of Health and the Pew Latin American Program.

Russian researchers together with their French colleagues discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor. The observation of these vortices provides direct evidence of induced quantum coherence. The pioneering experimental observation was supported by a first-ever numerical model that describes the induced vortices in finer detail.
These fundamental results, published in the journal Nature Communications, enable a better understanding and description of the processes occurring at the...
In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
