A new Michael Jordan of toxins isn’t required to increase crop protection against bugs as long as the right genes are strategically placed to take their shots at destructive insects, researchers report.
Plants modified with protectant genes designed to kill resistant insects can extend the usefulness of currently used pest-control methods and delay the development of pesticide-resistant bugs, according to Purdue University scientists and their collaborators from the University of Wisconsin-Madison, Monsanto Co., the University of Illinois and the University of California, Davis. The researchers’ findings appear in this month’s issue of the Journal of Theoretical Biology. "We always thought that it would take a Michael Jordan of toxins - a superstar of toxins to effectively halt insect resistance to the current generation of insecticides," said Barry Pittendrigh, a Purdue associate professor of entomology and lead author of the study. "We found that moderately effective genetically engineered protectants used in plants in the buffer zone around the main crops can play a major role in insect control, and they should be easier to identify than highly effective protectants. "You don’t find a superstar very often, but it may not be difficult to find good players, or worthwhile insect-control agents."
Farmers who use bioengineered crop protectants also use a buffer, or refuge, around the outside of fields that contains plants lacking the high-toxicity genetic modification in the main field that kills most insects. The refuge, usually about 20 percent of the acreage planted, delays development of insects resistant to the main-field, high-toxicity protectants, but some individuals in the destructive insect group have genes that allow them to survive.

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...
