Fans of one of Terry Pratchett’s early comic science-fiction novels The Dark Side of the Sun, will be familiar with the idea of robotic versions of insects being used as “bugs” to spy on people.
This is an idea that is being enthusiastically embraced by the US military, with many small UAVs in development for surveillance purposes.
And there is even more insect-themed biomimicry on it’s way from the labs: the dragonfly is of particular interest, according to researchers:
Dragonflies are one of few creatures that utilize four independently controlled wings to fly,
allowing them to hover, dart, glide, move backward, and change directions rapidly. Looking to understand such abilities, scientists at the Royal Veterinary College, in England, and the University of Ulm, in Germany, have developed a robotic dragonfly to measure the current flows over and under the wings at different flap cycles. While most of the dragonfly hovering scenarios were not efficient, the team found that if the lower wings are beating slightly ahead of the top wings, the double set of wings proves more efficient at generating lift, employing 22 percent less power to lift the same weight as a single pair.
Well good luck to them. Fortunately for privacy-lovers/paranoids it seems that practical fabrication of these insect spies is still some way in the future.

Just in case you hadn’t noticed,
The scientific community eagerly watches the progress as Pheonix lander scours Mars. They are hoping that there will be signs that there was once a supply of water on the planet that would give evidence that there may have once been life on the planet. Most scientists seem to conclude, though, that data from the Opportunity indicates that the water was a toxic mix of salty water and minerals that would have been unsuitable for Earth-like lifeforms.

Horror writers in search of a plot need look no further: a weasel-like predator known as the fisher is making itself right at home in your Northeast or Midwest suburbs! The mixture of eco- and morality tale make it the perfect story device, given that they were almost wiped out by trappers and foresters in the last century, but reintroduced to prey on porcupines.
