Long ago genetic engineering got deep reach into pharmacological and food industry, agriculture and medicine. The trees are no exclusion, but genetic engineers started to deal with them approximately ten years later than with other objects: the trees are too difficult for genetic investigations and manipulations. The wood plant genetic engineering activities are now in full swing in different countries of the world, including Russia. When improving trees through classical selection methods, the researchers first of all focus on the growth rate, wood quality, resistance to vermin and diseases, herbicides, salts and other stresses. Genetic engineering allows to do the same but much quicker. Russian scientists have obtained several accelerated growth wood species.
Specialists of the Siberian Institute of Physiology and Biochemistry of Plants, Northern Branch, Russian Academy of Sciences (Irkutsk), have applied classical methods and transformed via the corn gene ugt the aspen, poplar and Cembra pine (the latter being traditionally miscalled cedar). This gene codes the synthesis of the enzyme, which ensures the high level of vegetative hormone auxin. Auxin is necessary for the plant growth and development, and the trees with the respective corn gene do develop much quicker. Such plants could be used in the future in dedicated plantations with a short turnus. These plantations could be set up around woodworking enterprises. Such plantations will save primeval taiga woods from felling and would allow to reduce transportation costs for wood delivery to woodworking sites.
The researchers from the Research Institute of Wood Genetics and Selection (Voronezh) applied a different technology of getting trees from the cell culture. They have chosen the most valuable species - Karelian birch. The researchers selected the trees with the most beautiful patterned timber, got the cell culture – calluses - from their stems, and cultivated the birch-trees from the calluses. The long-term field trials have proved that the cloned trees grow well, within 3-4 years their stems become tuberous or ribbed – these are the exterior signs patterned timber. When the tree is 5-8 years old, all the birch-trees without exception are patterned. If the Karelian birch is cultivated from the seeds under a common technology, the signs of patterned timber appera much later – at the age of 10 to12.

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.
