Trapping Flies with Acoustics ... 11
A patent-pending artificial calling song attracts female Mediterranean fruit flies ­ nasty but common agricultural pests in most parts of the world as well as culprits of damage to more than 250 different types of fruit. The technique described in this feature can be used to attract the female flies in order to monitor and control the buzzing foragers.

Two is Better than One ... 13
The popularity of the use of UV disinfection in both drinking water and wastewater treatment is growing. However, application in a two-stage process including biological degradation to destroy organic contaminants is not common. Dena McMartin suggests that pre-treatment UV exposure, shown effective for cleaving complex, toxic organic molecules, may be good for reducing shock loading to existing biological treatment cells at industrial facilities.
