Research is key step in detoxifying endosulfan toward improving soil and water quality
Scientists at the University of California, Riverside report in the Journal of Environmental Quality (JEQ) that they have isolated microorganisms capable of degrading endosulfan, a chlorinated insecticide widely used all over the world and which is currently registered to control insects and mites on 60 U.S. crops. JEQ, established in 1972, is published jointly by the American Society of Agronomy, Crop Science Society of America, and the Soil Science Society of America.
Bioremediation of contaminated sites and water bodies by using these microbial strains will provide an environment free of endosulfan toxicity, the researchers argue in their paper. The research stands to benefit the agrochemical industry and environmental agencies involved in remediation of soil and water contaminated with organochlorine pesticides. Currently, bioremediation is considered the most cost-effective technology to remediate contaminants, including pesticides. The usefulness of the new technology may be best measured economically in soil and water quality impacted by pesticide spillage, overdosing, and cleanup of agrochemical equipment.

Fraunhofer researchers are investigating the potential of microimplants to stimulate nerve cells and treat chronic conditions like asthma, diabetes, or Parkinson’s disease. Find out what makes this form of treatment so appealing and which challenges the researchers still have to master.
A study by the Robert Koch Institute has found that one in four women will suffer from weak bladders at some point in their lives. Treatments of this condition...
The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.
Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.
Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
