Cotton plantations are highly important in Egypt, covering between 400 000 and 500 000 ha, 1/6 of all cultivated land. These crops are a vital source of foreign currency revenue through exports, and their state of health is therefore permanently under close surveillance. Cotton plants are indeed the target of a leaf-eating insect, the noctuid Spodoptera littoralis (Lepidoptera), or Egyptian Cotton Leafworm.
Known to be the main pest of cotton, it also attacks the leaves of cereal crops and lucerne which is the principal fodder crop used in Egypt. This noctuid is one of the most intensively studied insects in that country. The problem that arises concerns how to eradicate populations of this pest without massive use of chemical pesticides and thus minimize damage to the environment, and in such a way that crop yields are not jeopardized.
The solution put forward by researchers from the IRD, the University of Cairo and their French and Canadian partners (1) lies in the domestication of an insect-infecting virus isolated in Egypt in 1995, Densovirus MlDNV (2). This organism could be used locally as an element of biocontrol programmes.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
Just in time for Christmas, a Mars-analogue mission in Morocco, coordinated by the Robotics Innovation Center of the German Research Center for Artificial Intelligence (DFKI) as part of the SRC project FACILITATORS, has been successfully completed. SRC, the Strategic Research Cluster on Space Robotics Technologies, is a program of the European Union to support research and development in space technologies. From mid-November to mid-December 2018, a team of more than 30 scientists from 11 countries tested technologies for future exploration of Mars and Moon in the desert of the Maghreb state.
Close to the border with Algeria, the Erfoud region in Morocco – known to tourists for its impressive sand dunes – offered ideal conditions for the four-week...
