The Aral Sea was once the fourth-largest lake in the world. Fed primarily by snowmelt and precipitation flowing down from faraway mountains, it was a temperate oasis in an arid region. But in the 1960s, the Soviet Union diverted two major rivers to irrigate farmland, cutting off the inland sea from its source. As the Aral Sea dried up, fisheries collapsed, as did the communities that depended on them. The remaining water supply became increasingly salty and polluted with runoff from agricultural plots. Loss of the Aral Seaās water influenced regional climate, making the winters even colder and the summers much hotter.
While seasonal rains still bring water to the Aral Sea, the lake is roughly one-tenth of its original size. These satellite images show how the Aral Sea and its surrounding landscape has changed over the past few decades.

Awesome. Can't wait to check it out.
Watch the Perseid Meteor Shower at Its Peak Tonight
The last time we had an outburst, that is a meteor shower with more meteors than usual, was in 2009. This yearās Perseid meteor shower is predicted to be just as spectacular starting tonight!
Plan to stay up late tonight or set your alarm clock for the wee morning hours to see this cosmic display of āshooting starsā light up the night sky. Known for itās fast and bright meteors, tonightās annual Perseid meteor shower is anticipated to be one of the best meteor viewing opportunities this year.
For stargazers experiencing cloudy or light-polluted skies, a live broadcast of the Perseid meteor shower will be available via Ustream overnight tonight and tomorrow, beginning at 10 p.m. EDT.
āForecasters are predicting a Perseid outburst this year with double normal rates on the night of Aug. 11-12,ā said Bill Cooke with NASAās Meteoroid Environments Office in Huntsville, Alabama. āUnder perfect conditions, rates could soar to 200 meteors per hour.ā
Every Perseid meteor is a tiny piece of the comet Swift-Tuttle, which orbits the sun every 133 years. When Earth crosses paths with Swift-Tuttleās debris, specks of comet-stuff hit Earthās atmosphere and disintegrate in flashes of light. These meteors are called Perseids because they seem to fly out of the constellation Perseus.
Most years, Earth might graze the edge of Swift-Tuttleās debris stream, where thereās less activity. Occasionally, though, Jupiterās gravity tugs the huge network of dust trails closer, and Earth plows through closer to the middle, where thereās more material.
This is predicted be one of those years!

Beautiful hand art.

I'm not waiting around for this. š
The experiment demonstrates the fluidity and high viscosity of pitch, a derivative of tar that is the world's thickest known fluid and was once used for waterproofing boats.
Thomas Parnell, UQ's first Professor of Physics, created the experiment in 1927 to illustrate that everyday materials can exhibit quite surprising properties.
At room temperature pitch feels solid - even brittle - and can easily be shattered with a hammer. But, in fact, at room temperature the substance - which is 100 billion times more viscous than water - is actually fluid.
In 1927 Professor Parnell heated a sample of pitch and poured it into a glass funnel with a sealed stem. He allowed the pitch to cool and settle for three years, and then in 1930 he cut the funnel's stem.
Since then, the pitch has slowly dripped out of the funnel - so slowly that it took eight years for the first drop to fall, and more than 40 years for another five to follow.
Now, 87 years after the funnel was cut, only nine drops have fallen - the last drop fell in April 2014 and we expect the next oneĀ to fall sometime in the 2020s.
The experiment was set up as a demonstration and is not kept under special environmental conditions - it's kept in a display cabinet - so the rate of flow of the pitch varies with seasonal changes in temperature.
The late Professor John Mainstone became the experiment's second custodian in 1961. He looked after the experiment for 52 years but, like his predecessor Professor Parnell, he passed away before seeing a drop fall.
