Recent research results by two physicists from the Niels Bohr Institute at University of Copenhagen, Thomas Heimburg and Andrew D. Jackson, cast doubt on the generally accepted theory of nerve activity. Their new theory of how nerves function emphasizes the essential role that temperature and pressure play in nerves. This result can contribute to a better understanding of the effect of drugs on nerve activity and will be published in the presitigous American journal Proceedings of the National Academy of Sciences.
It is generally accepted in biology that nerve pulses are governed by so-called protein channels that open and close. According to the classic theory, electrical currents passing through open protein channels create the nerve pulses that are the basis of the brain’s activity and of its communication with muscles. This theory stands unchallenged in textbooks and earned the Nobel Prize in 1963 for its inventors, the British scientists Alan L. Hodgkin and Andrew F. Huxley.
According to Heimburg and Jackson, nerve pulses are more appropriately described as localized sound waves called ”solitons”. Perhaps nerves communicate to a larger extent with pulses of sound than with electrical signals. Scientists at the Niels Bohr Institute have been led to this new view of nerve pulses by new experimental results and by the results of a number of classical experiments not addressed by the Hodgkin-Huxley theory.

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.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
