A hanging basket style device is at the heart of a plan by researchers at the University of Warwick to harness the sex drive of a major pest of fruit orchards as a weapon to spread a virus to kill that very same pest. The device allows growers to selectively target the pest with a virus that kills its larvae without killing other beneficial insects.
The researchers at Warwick HRI, the horticultural research arm of the University of Warwick, have devised a hanging basket style dispenser full of a virus known to kill the larvae of codling moth. The dispenser is designed to protect the virus from the elements and also includes a strong source of codling moth pheromone. The pheromone draws in the moth hoping for a sexual encounter and the insect leaves frustrated but covered in the virus which it then passes on to other moths when it does manage to have an actual encounter with another real moth. This results in direct contamination of eggs laid by the pest or contamination of the site where the moth lays its eggs. The larvae are killed after eating the virus on the egg or plant surface. This brings two key benefits to fruit growers:
An end to spraying - Normally Growers wishing to use this form of virus warfare have to spray almost every element of an orchard to ensure the moths come into contact with virus. This is wasteful both of time and resources. By this method the moth themselves spread the virus in a very targeted way to other moths and prevents loss of populations of other beneficial insects such as the red spider mite which would occur if growers used pesticides.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

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...
