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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
