Scientists have developed a new technique that makes pesticides more effective by removing insects ability to exhibit resistance. Their research will extend the effective life of current pesticides, significantly reduce the amount that needs to be sprayed and remove the need for farmers to move to stronger and more harmful chemicals.
Researchers at Rothamsted Research in Hertfordshire, working with researchers in New South Wales, Australia have developed a way to counter the pests most common way of becoming resistant and in trials it has proved to be almost 100 per cent effective.
Resistance to pesticides is a global problem, which is hitting tropical and developing countries particularly hard. Insect pests often develop resistance by over-producing enzymes that degrade the effectiveness of a pesticide. The Rothamsted scientists, supported by the Biotechnology and Biological Sciences Research Council (BBSRC), have developed a product that blocks the enzymes and then delivers a dose of pesticide 4-5 hours later to kill the newly defenceless insect.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
