- A mosquito only weighs 1/25,000 of an ounce.
- Mosquitoes are responsible for more human deaths than any other living creature.
- There are over 2,500 species of mosquitoes scattered throughout the world.
- Hundreds of thousands of mosquitoes are born every day.
- Most adult mosquitoes live for about two weeks, while some species can live as long as 5 months.
- Only female mosquitoes bite—they need the protein for their eggs.
- Male mosquitoes survive by sucking on nectar and other plant juices.
- The welt that appears after a mosquito bites is an allergic reaction to the saliva that is injected into your skin to prevent your blood from clotting.
- Mosquitoes rarely travel farther than 300 feet from their birthplace.
- Light colors are less attractive to mosquitoes than dark colors; thus, mosquitoes are more likely to choose a victim wearing darker colors.
- Mosquitoes are found all over the world, even in cold places like the Arctic.
- Arctic researchers uncovered their chests, arms, and legs and reported as many as 9,000 mosquito bites per person, per minute. At this rate, an unprotected human would lose one half of his or her blood supply in approximately 2 hours!
- Some people are more attractive to mosquitoes than others. It is not clear why, but probably has something to do with the 300 odd chemicals produced by the skin.
- Mosquitoes prefer dark places like trees, grass and shrubs.
- Like humans, mosquitoes have food preferences—not all mosquito species bite humans, some prefer birds, horses, frogs or turtles.

MELBOURNE (Reuters) - Caught Twittering or on Facebook at work? It'll make you a better employee, according to an Australian study that shows surfing the Internet for fun during office hours increases productivity.
The University of Melbourne study showed that people who use the Internet for personal reasons at work are about 9 percent more productive that those who do not.
Study author Brent Coker, from the department of management and marketing, said "workplace Internet leisure browsing," or WILB, helped to sharpened workers' concentration.
"People need to zone out for a bit to get back their concentration," Coker said on the university's website (www.unimelb.edu.au/)
"Short and unobtrusive breaks, such as a quick surf of the Internet, enables the mind to rest itself, leading to a higher total net concentration for a days' work, and as a result, increased productivity," he said.
According to the study of 300 workers, 70 percent of people who use the Internet at work engage in WILB.
Among the most popular WILB activities are searching for information about products, reading online news sites, playing online games and watching videos on YouTube.
"Firms spend millions on software to block their employees from watching videos, using social networking sites or shopping online under the pretence that it costs millions in lost productivity," said Coker. "That's not always the case."
However, Coker said the study looked at people who browsed in moderation, or were on the Internet for less than 20 percent of their total time in the office. Continued...

The Bill & Melinda Gates charitable foundation has awarded 104 grants, each for $100,000, in a bid to inject entrepreneurial boldness and risk-taking into the often staid world of medical research ....... The winning grants offer a bewildering array of ideas from a bewildering array of researchers. Hiroyuki Matsuoka of Jichi Medical University in Japan wants to turn mosquitoes into flying syringes to deliver vaccines rather than illness.
