Even in places as seemly well-studied as the national parks of North America, new species are still being discovered. Using ultraviolet light that cause scorpions to fluoresce a ghostly glow, researchers from the University of Nevada, Las Vegas (UNLV) have discovered an intriguing new scorpion in Death Valley National Park. They named the species Wernerius inyoensis, after the Inyo Mountains where it was found. The study was published in the open access journal ZooKeys.

This new species is small, only 16 mm in length. "We almost overlooked this one during the survey" said Matthew Graham, a PhD Candidate with the School of Life Sciences at UNLV. Matt discovered the scorpion along with his father who was volunteering that night. "Only a single male individual was found, but the physical uniqueness was enough to identify it as a new species", said Michael Webber, another PhD Candidate from UNLV who described the specimen. This new scorpion appears to be closely related to two other species found over 400 kilometers away at Joshua Tree National Park and along the lower Colorado River. This group of scorpions is most easily identified by the presence of a conspicuous spine at the base of the stinger, the function of which, if any, is unknown.
The previously known species are also rarely observed in the wild, and this elusive nature has led to speculation that these scorpions occur at very low densities or have only sporadic surface activity. However, the rocky terrain in which the previous species were found and the discovery of the new species at the base of a talus slope, hint at the possibility that these scorpions are subterrestrial, spending their lives deep in rock crevices or in the interstitial spaces among piles of loose rock.
Scorpions are quite common within arid regions where they can comprise a large component of biological diversity. The new species was discovered during field surveys funded by the National Park Service as part of efforts to develop better inventories for all organisms occurring within the parks.
"In North America, inventories for mammals, birds, reptiles and amphibians are pretty well developed, and we have a good handle on higher-order plants, but for many groups of smaller organisms taxonomic inventories will no doubt lead to numerous new discoveries" said Dr. Jef Jaeger, a Research Assistant Professor at UNLV who initiated and oversaw the scorpion surveys.
In the face of regional environmental changes brought about by human actions and the potential for larger changes that global warming may bring, many scientists and resource managers place new importance on efforts to document and catalog species diversity.

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.
