Mosquito
A research project that began in 2004 and involved 38 institutions around the world has culminated in the sequencing of the Culex mosquito genome. Culex is one of the three mosquito genera, the other two – Anopheles and Aedes – having already been sequenced in 2002 and 2007, respectively. It is also the genus that obtains the West Nile virus from infected birds and transmits it to humans. Scientists hope that by better understanding the mosquito, they may be better able to control the spread of the virus. Read More
Natural tool tells mosquito moms to lay their eggs someplace else
Mosquitoes could be having a tough time of it before too long. First, scientists announced an experimental new technology that utilizes gene-silencing nanoparticles to keep mosquito larvae from fully developing their protective exoskeletons. This leaves them much more vulnerable to insecticides, once they become adults. Now we have word of another study, in which researchers have identified a natural, environmentally-friendly chemical compound that causes female skitters to go elsewhere to lay their eggs. Read More
To most Gizmag readers, mosquitoes are at most a pesky nuisance - for others of course, particularly in more tropical areas, they're a genuine killer, spreading all sorts of diseases as they feed on the blood of their victims. Either way, the mosquito female's habit of biting humans puts mozzies high on the list of most hated insects - so many will appreciate this study from Kansas State University, in which researchers have successfully used nanoparticles impregnated with gene-silencing dsRNA to specifically target particular genes in mosquito larvae. A small supply of these nanoparticles, added to a still water breeding ground, can kill mozzie larvae as they grow, or at the least, render them much more susceptible to insecticides… And the process is fascinating.

With a very sturdy folded steel frame and elegant simple design, the Mosquito or Mücke electric bike is one good-looking machine. Its 48V lithium batteries only cost a few (European) cents to charge up and will give a range of about 60km (37 miles). The 0.8kW motor produces a top speed of around 50km/h (31mph) and the bike also has a removable center pole for instant accessibility. Read More
