The new breed blooms longer, produces more flowers and grows under a wider range of temperatures than existing cherry blossom trees, demonstrating the power of accelerator technology in horticulture.
To create the new breed, researchers used beams of carbon ions from the RIKEN Ring Cyclotron at the RI Beam Factory to induce mutations in branches from the cherry blossom tree known as Keiou-Zakura No. 13. The branches were grafted and cultivated to create the new breed, which has been aptly named ‘Nishina Otome’.
Unlike regular cherry blossom trees, Nishina Otome does not require a period of cold weather to trigger growth. As a result, the new tree is able to bloom all year round when cultivated indoors, and during autumn and spring when grown outdoors. Given sufficient exposure to low temperatures, it produces three times more flowers than the regular varieties, and its spring bloom lasts for twice as long.
The use of heavy ion beams to generate new breeds of plants by mutagenisis, an approach to horticulture unique to Japan, is drawing attention worldwide as a powerful alternative to conventional genetic engineering that is capable of shrinking breeding times to only a few years. The second breed of cherry blossom tree to be registered by RIKEN, the Nishina Otome hints at an exciting future for accelerator-based mutation breeding, one which opens the door to the design of plant varieties better able to cope with a changing environment.

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...
