and warbles of wild birds and match them against a database of bird sounds to help the oereader identify the species

or to track mosquitoes, or that he belonged to an lite team of ghost hunters.

as long as they get a waiver and fly them within a specific area. We are concerned about any (Unmanned Aircraft Systems) operation that poses a hazard to other aircraft or to people and property on the ground,

The protein is very selective generally not harming insects in other orders (such as beetles flies bees and wasps.

It would indeed take 8 minutes for the Earth to leave its orbit and fly away into space.

and streams to keep mosquitoes from breeding. Such practices would be frowned upon today but apparently these methods saved thousands of lives in the early 1900s.

The land of the jungle where the mosquito sang her weird song of death unmolested for four hundred years vying with the germs of dysentery typhoid fever and pneumonia in the destruction of human life;

In comparison with similar expenditures in American cities it should not be forgotten that practically nine-tenths of the cost of sanitation in the Zone is in mosquito fighting and quarantine.

and malarial mosquitos thrive in countless millions; the perpetual moisture warmth and rich soil lead to extravagant growth of hundreds of varieties of tropical grasses plants flowers vines and trees furnishing favorable harbor for the insects;

Decaying animal matter leads to the generation of innumerable flies ever ready to convey disease

the cisterns puddles and lakes furnished convenient breeding places for mosquitos; the streets and sidewalks were in horrible condition

and flies literally swarmed over the food. The conditions were little better in Panama city and in the intermediate towns.

Gorgas himself says that the Americans could have done no better than The french without the knowledge of the mosquito as a disease carrier.

so that the operatives might be protected from mosquitoes during sleeping hours. Colon and Panama city are in the Zone

and marshes so that mosquitoes could not breed. Each little station or town was furnished a pure water supply brought down from the distant hills in some instances and provided with an efficient system of sewers or in some rare instances well arranged cesspools.

so that the mosquito could find no resting place. Plague-carrying rats and other vermin were destroyed.

This proposition was demonstrated beyond all question in a great educational campaign on the mosquito in the San antonio public schools several years ago in

which the mosquito was exterminated completely. It is an inspiring sight to witness this unseemly death-ridden tropical country changed into a place of beauty

and Vaneck watched as a fly appeared to slam into a window. Instead of breaking apart on contact as their drones did bounced the insect off the glass and recovered.

But until recently inventors lacked the aerodynamics expertise to turn diagrams into mechanical versions of something as quotidian as a fly or a bee.

At the University of California at Berkeley neurobiologist Michael Dickinson built a robotic fruit-fly wing that likewise mimicked a fly s natural motion

Dickinson and electrical engineer Ron Fearing won a $2. 5-million DARPA grant in 1998 to apply these principles to a fly-size robot.

Flies have really complex wing trajectories. There are a whole bunch of subtle things that happen Wood says.

On the workbench sat a 60-milligram robot with a three-centimeter wingspan and a thorax roughly the size of a housefly.

After observing the fly at the bar the two engineers searched for someone with experience replicating insect flight.

By closely observing the positions of the flies body parts they could measure the exact flip and twist of wings and legs.

I thought the fly would tumble a bit and lose a lot of altitude Vaneck says. But the fly recovery was elegant.

Just before the moment of impact the fly flew at an angle that ensured its legs touched the glass first.

Every time the fly slammed into the window it reflexively surrendered to the crash momentum and fell.

Fifteen years ago the flies looked like little fuzzy UFOS he says. Now the biologists use cameras that can run at 7500 frames per second significantly higher than what was once available to researchers and that work in infrared light.
