Movie - Madagascar Escape 2 Africa
Finally the second Madagascar movie is out. It's going to be in theaters on the eleventh of July! Here's the Trailer:
Summer is in front of the door and everybody is looking for sunglasses...My personal tip for this summer are the Ray Ben wayfarer (pic above). They perfectly fit the new retro style which is becoming more and more popular. But the Ray ben wayfarer are not some new sunglasses Ray Ben just brought with their new collection, no they've been quiet a long time on the market now. You also saw them in famous movies like Men in Black or . The price in Europe is 109 € and in America 100 $. So I would buy them online from America to save the 40% ;). Ofcause they're available in different colors.

Auroras are caused when high-energy electrons pour down from the Earth's magnetosphere and collide with atoms. (Credit: Image courtesy of NASA (Crew of STS-39))
Space Weather: Interfering With The Global Positioning System
You can't always trust your GPS gadget. As scientists have long known, perplexing electrical activity in the upper atmospheric zone called the ionosphere can tamper with signals from GPS satellites.
Now, new research and monitoring systems are clarifying what happens to disruptive clouds of electrons and other electrically charged particles, known as ions, in the ionosphere. The work may lead to regional predictions of reduced GPS reliability and accuracy.
One team of researchers has recently observed Earth's aurora, which is a prominent manifestation of ionospheric electrical activity, in the act of disrupting GPS equipment. Other scientists have successfully tested a way to forecast GPS disturbances for marine users, with likely extension to users on land.
Some research groups are turning the tables and employing GPS receivers as tools with which to conduct basic research on the electrical-current structures of the ionosphere.
The scientific reports on these and other recent developments are available in a special section of Space Weather: The International Journal of Research and Applications, a publication of the American Geophysical Union, or AGU.
Space Weather is an online journal devoted to studies of the electrical interactions between the Earth and various emissions from the Sun, including electrically charged particles (the solar wind), solar radio noise and solar X-rays. The journal, which has a quarterly print digest called Space Weather Quarterly, is cosponsored by the National Science Foundation and the International Space Environment Service.

Mercury Contamination Found In Stranded Victorian Dolphins
Monash University research into heavy metal contaminant levels in dolphins from Port Phillip Bay and the Gippsland Lakes has revealed high mercury levels may be a contributing factor to dolphin deaths.
Researchers from the School of Biological Sciences have confirmed levels of mercury found in the dolphins were within a range considered to cause negative health and mental effects and were higher than mercury levels found in populations around the world.
Supervisory researcher Dr Ross Thompson said the mercury concentrations in 20 live and eight dolphins which died after becoming stranded, collected over the last two years, were measured by Honours student Alissa Monk. Levels in the dead dolphins averaged 3.45 milligrams of mercury per kilogram of tissue compared to 1.32 mg/kg in living dolphins.
"Mercury levels detected are sufficient to cause significant health impacts and were comparable to those found in areas of the world that are considered highly polluted, including the Mediterranean Sea," Dr Thompson said.
Mercury has been shown in previous national studies to bioaccumulate in dolphins, but this is the first study to find particularly high levels in stranded animals in coastal Victoria. Bioaccumulation is the food chain process whereby smaller fish containing mercury are eaten by larger mercury contaminated fish, which are then consumed by dolphins, who can consume up to ten kilograms of fish a day. Mercury levels found in fish were considered low (<0.5>
"Dolphins may be becoming stranded as a direct consequence of mercury contamination which damages their neurological system. They become potentially confused and disorientated, and strand themselves. Even the apparently healthy dolphins had high levels of mercury which put them at risk of future health complications," Dr Thompson said.
Dr Thompson said mercury is likely to have come from the sediments of the Bay and researchers are concerned that dredging activities may increase the dolphins' exposure.
"Sediment contains mercury, which is likely to have originated from historical gold mining sites where mercury was used in gold processing, as well as from other industrial sources. Over time, the mercury has been washed down through waterways, including the Yarra River, and come to rest on the bottom of the Bay," Dr Thompson said.
Dr Thompson said it was critical that further studies were done throughout the bay dredging process to ensure any further decline in dolphin health could be identified and managed.
