The second Duke University-led expedition since 1999 to a deep underwater canyon will take geologists to another place in the eastern Pacific Ocean where new sea floor was forged out of volcanic lava within the past several million years.
The Pito Deep trough, positioned as deep as 19,600 feet below the ocean’s surface just west of Easter Island, will offer scientists a rare chance to study the internal geology of such ocean floor crust making processes.
The internal geology is accessible in the rift because it opens up the geologically young crust like a layer cake slice as thick as 1 1/2 miles, exposing now cooled and hardened conduits that once channeled molten rock towards the ocean floor surface. "Our investigation will look at the architecture of the crust and the composition of the rock that’s there," said the expedition’s chief scientist, Jeff Karson, who is a geology professor with Duke’s Nicholas School of the Environment and Earth Sciences. "There will always be surprises," Karson added. "We know so little about the submerged part of our planet that we find something new and exciting virtually every time we travel to the seafloor."

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...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
