A Martian Mineral History
The large dark area right of center on the hemisphere view of Mars is Syrtis Major. The map shows the presence of water-bearing clay minerals identified by OMEGA data. Blue indicates small amounts and orange-red indicates large amounts.
An international team of scientists, including Brown University geologist John Mustard, has created the most comprehensive mineral record of Mars to date. Using data from the European Space Agency’s Mars Express mission, the record shows three distinct geological eras on the Red Planet, with the earliest marked by the presence of water. Results are published in Science.
Mars started out relatively wet and temperate, underwent a major climate shift, and evolved into a cold, dry place strewn with acidic rock – less than ideal conditions for supporting life.
This is the finding of an international team of scientists who have created the most comprehensive mineral history of Mars, a history closely linked to the presence of liquid water on the planet. According to the mineral record, created with Mars Express mission data and detailed in Science, Mars would only have been hospitable to life in its infancy.
The team’s analysis led them to draw an intriguing conclusion: Liquid water didn’t make the Red Planet red. Instead, the team states, Mars most likely gets its glow from tiny grains of red hematite or possibly maghemite, both riddled with iron.
The Centre National d’Etudes Spatiales, Agenzia Spatiale Italiana and the Russian Space Agency funded the OMEGA instrument. In the United States, NASA supported OMEGA data analysis.

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...
