Are you stressed-out? let my mosquito diagnose you!
It appears that some chemicals in human odors, which could be related to stress, are powerful repellents.
I have hungry Aedes ...any volunteers?

How Mosquitoes Work

What postdocs want
by Bryan Venters, Postdoc journal
I want to hear that I have a job and that my manuscript's been accepted.
A goal all postdocs share is to publish their work so that they can build a competitive resumé. Recently I realized that the challenges of publishing a manuscript are strikingly parallel to many of the hurdles I will face when seeking a job. A few months ago I had an article published in Genome Research (B. J. Venters and B. F. Pugh Genome Res. 19, 360–371; 2009). The process of getting this and other papers published taught me some important lessons about applying for jobs.
First, finding a journal suitable for my manuscript is analogous to finding a position for which I am qualified. In other words, I seek to publish in a journal that is most relevant to my field and has the highest readership. However, if I misjudge the suitability of a manuscript for a particular journal, then the submission may be an exercise in futility. In the same way, whether in academia or industry, it is critical that I match my skills with the right position. Publishing papers requires tenacity, and this trait extends to mounting a successful job search.
Second, manuscript peer review is much like a job interview because my work is scrutinized and a decision is made one way or another. During peer review, I want to persuade the reviewers that my work is novel and represents a significant contribution to the field. Similarly, in a job interview, my goal is to convince others that my unique blend of skills and experiences will be an asset to the university, institution or company to which I am applying. Two phrases I hope to hear in the future are, "Your manuscript has been accepted" and "You're hired".

I make the last phrase my words.

Some General Mosquito facts
- 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.

Breaks and web-surfing makes better postdocs
Facebook, YouTube make better postdocs: study
Thu Apr 2, 2009 9:50am EDT
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...

Mosquitoes Are The Toughest Living Beings - Or Aliens?
"We brought him back to Earth. He is alive, and his feet are moving," Anatoly Grigoryev of the Russian Academy of Sciences told RIA Novosti.
The buzzing bug was part of a larger experiment in which bacteria, barley seeds, small crustaceans and larval insects were placed in a container strapped to the exterior of the space station, which orbits in zero gravity about 200 miles above the surface of the Earth.
From the RIA Novosti report, it wasn't clear if the insect — which may in fact be a non-biting midge rather than a mosquito — was placed in the container in the larval or the adult stage.
A European Space Agency experiment last fall found that primitive animals called tardigrades, also known as water bears, survived an even harsher exposure to space, including full vacuum and direct solar ultraviolet blasts. Moreover, several of the surviving tardigrades were able to normally reproduce. FOX NEWS Tuesday, February 24, 2009 .

An Interesting Solution to the Mosquito Problem
John Rosa, a 23-year resident of Alaska, reports a method that is probably not familiar to many of us. It requires at least one other participant. To quote: "First, when going fishing, camping, mining or even gardening, before you start, give your partner, wife, sweetheart or mother a banana. This produces a scent through the pores of their skin which attracts mosquitoes to them, leaving you relatively free."
Another of Mr. Rosa's recommendations, which may (or may not be) quite as tongue-in-cheek, is that a used Bull Durham bag filled with mothballs and hung outside the tent not only keeps mosquitoes away from the campsite, but also wards off black bears."

THE MOSQUITO POEM (by William Cullen Bryant)
Fair insect! that with threadlike legs spread out
And blood-extracting bill and filmy wing,
Dost murmur, as thou slowly sail'st about,
In pitiless ears, full many a plaintive thing,
And tell how little our large veins should bleed,
Would we but yield them to thy bitter need?
Unwillingly I own, and, what is worse,
Full angrily men hearken to thy plaint;
Thou gettest many a brush and many a curse,
For saying thou art gaunt and starved and faint.
Even the old beggar, while he asks for food,
Would kill thee, hapless stranger, if he could.
I call thee stranger, for the town, I ween,
Has not the honor of so proud a birth-
Thou com'st from Jersey meadows, fresh and green,
The offspring of the gods, though born on earth;
For Titan was thy sire, and fair was she,
The ocean nymph that nursed thy infancy.
Beneath the rushes was thy cradle swung,
And when at length thy gauzy wings grew strong,
Abroad to gentle airs their folds were flung,
Rose in the sky, and bore thee soft along;
The south wind breathed to waft thee on thy way,
And danced and shone beneath the billowy bay.
Calm rose afar the city spires, and thence
Came the deep murmur of its throng of men,
And as its grateful odors met thy sense,
They seemed the perfumes of thy native fen.
Fair lay its crowded streets, and at the sight
Thy tiny song grew shriller with delight.
At length thy pinion fluttered in Broadway--
Ah, there were fairy steps, and white necks kissed
By wanton airs, and eyes whose killing ray
Shone through the snowy veils like stars through mist;
And fresh as morn, on many a cheek and chin,
Bloomed the bright blood through the transparent skin.
Sure these were sights to tempt an anchorite!
What! do I hear thy slender voice complain?
Thou wailest when I talk of beauty's light,
As if it brought the memory of pain.
Thou art a wayward being--well--come near,
And pour thy tale of sorrow in mine ear.
What say'st thou, slanderer! rouge makes thee sick?
And China Bloom at best is sorry food?
And Rowland's Kalydor, if laid on thick,
Poisons the thirsty wretch that bores for blood.Go!
'Twas a just reward that met thy crime-
But shun the sacrilege another time.
That bloom was made to look at--not to touch;
To worship--not approach--that radiant white;
And well might sudden vengeance light on such
As dared, like thee, most impiously to bite.
Thou shouldst have gazed at distance and admired-
Murmur'd thy admiration and retired.
Thou'rt welcome to the town--but why come here
To bleed a brother poet, gaunt like thee?
Alas! the little blood I have is dear,
And thin will be the banquet drawn from me.
Look round--the pale-eyed sisters in my cell,
Thy old acquaintance, Song and Famine, dwell.
Try some plump alderman, and suck the blood
Enrich'd by gen'rous wine and costly meat;
On well-filled skins, sleek as thy native mud,
Fix thy light pump, and press thy freckled feet.
Go to the men for whom, in ocean's halls,
The oyster breeds and the green turtle sprawls.
There corks are drawn, and the red vintage flows.
To fill the swelling veins for thee, and now
The ruddy cheek, and now the ruddier nose
Shall tempt thee, as thou flittest round the brow;
And when the hour of sleep its quiet brings,
No angry hand shall rise to brush thy wings.
William Cullen Bryant (November 3, 1794 - June 12, 1878)
