Bluetongue disease has been seen in northern Europe and continental France for the first time

CIRAD and its partners are in the front line

Since 1999, Bluetongue (BT) has been spreading from the southern and eastern Mediterranean towards northern Europe. Between 2000 and 2004, foci were also observed in Corsica. Vast vaccination campaigns subsequently overcame the disease, which is transmitted to sheep by biting midges of the genus Culicoides.

As Emmanuel Camus, Director of CIRAD's Animal Production and Veterinary Medicine Department, explains: "global warming is favouring the arrival of diseases previously seen as exotic". He adds "we also need to cope with the appearance of different strains serotypes) of the Bluetongue vieus, which means using specific vaccines".

CIRAD is the national reference laboratory for the disease, and will be analysing samples taken by veterinary services from sheep and cattle on 60 farms in six of the départements most concerned (Moselle, Meurthe et Moselle, Meuse, Ardennes, Aisne and Nord), and will be trapping vector insects in those areas.

It is also carrying out research, primarily on:

- molecular characterization of vector insects: this will enable the precise identification of species in terms of morphologically indistinguishable groups or complexes and characterization of their reproduction sites, since it is impossible to identify species at the larval stage;

- the development of a new recombinant vaccine effective on all serotypes (in partnership with AFSSA and INRA);

- assessing Bluetongue serological diagnostic kits;

- spatial modelling of the zones propitious to vectors and dynamic modelling of viral infection so as to pinpoint the zones to be monitored in continental France. Several models are currently being developed and evaluated;

- application of the risk evaluation methodology concerning introduction of the virus into disease-free zones through commercial animal movements.

CIRAD is also coordinator of the European Med_Reo_Net project on Bluetongue and another disease caused by a similar virus: African horse sickness. The project, which involves 17 countries, will be launched in Autumn 2006.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

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...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

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...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

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...

Im Focus: New Products - Highlights of COMPAMED 2016

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...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'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...
