The hide, recently developed by scientists in Switzerland, consists of a skin-like silicone membrane, complete with hair that rests over a layer of cow blood. The insects are so comfortable with the faux-cow that they set up home, copulate and laid eggs.
But it is knee trembling of a different kind that researchers measure to evaluate the early signs of pesticide toxicity. Researchers use the leg tremblings of the tick (Ioxedes ricinus) to observe the early stages of central nervous system damage, something that is not possible using live animals.
Thomas Kröber and Patrick Guerin at the University of Neuchâtel confirmed the effectiveness of the system by coating the membrane with the chemical firponil, and then observing central nerve system damage (leg trembling) and measuring tick mortality (Pest Management Science DOI:10.1002/ps.1293).
Vicky Robinson, chief executive of the National Centre for the Replacement, Refinement and Reduction of Animals in Research, said: 'This research takes a simple idea and applies it to great effect, resulting in a potentially significant impact on animal use. Most importantly, it demonstrates that finding ways to reduce the use of animals in research and testing is as much about improving the science as it is about considering the welfare of animals.’
More than 10,000 animals are used every year to test new tick-fighting chemicals, a figure that is likely to increase with the introduction of REACH, the EU new chemicals legislation, next year. Pesticides targeting ticks are constantly being updated and tested, because pests develop resistance so quickly. Ticks transmit several serious diseases to both animals and humans, including Lyme disease.

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...
A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
