Long droughts, heavy rainfall, hailstorms, cold and late frost – extreme weather events cause substantial damage in the agricultural sector. Researchers at the Leibniz Centre for Agricultural Landscape Research (ZALF) are investigating in a new project to what extent such extreme weather events can be better predicted and damage prevented or limited.
The aim of the project funded by the Federal Ministry of Food and Agriculture (BMEL) is to develop an extreme weather monitoring and risk assessment system (EMRA). As a first step, specific risks for agriculture, such as crop failures or soil erosion, are to be analysed and thus better assessed through the systematic recording of actual extreme weather events and their damage.
The main focus is on the consequences of hail, cold and late frost, waterlogging, heavy rainfall, drought and heat. In the case of waterlogging and heavy rainfall, immediate risks to the ecosystem are investigated and local management measures derived from these.
These are intended to prevent soil fertility from being endangered by erosion, for example, and to prevent adjacent ecosystems from being polluted by pesticide and fertiliser inputs. Based on two model regions and cultures, Apple in the Altes Land (Lower Saxony and Hamburg) and Winter wheat in the Uckermark (Brandenburg), a system is being developed during the three-year project in cooperation with project partners and agricultural enterprises, that provides practical decision-making aids for short to long-term extreme weather management.
“An important component here is the development of suitable communication channels”, says Dr. Detlef Deumlich, agricultural engineer at ZALF. “Therefore, in addition to an Internet platform, an app for mobile devices is also being developed to support farmers and fruit growers with their daily decisions.”

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.

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.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
