For our second Best Of Syndication, we again take a look around the world with some of our favorite syndicated posts from striking images of the Japanese tsunami damage, to the incredible city lights of Dubai, to the health implications of a mild winter and its effects on mosquito populations.

Agra, India’s famed Taj Mahal – a token of love built in the 1600′s – might be slowly sinking. As the Yamuna River slowly dries up, the building’s foundations are being compromised as the soil it rests upon derives much of its strength from soil moisture provided by the river.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured amazing images of much of Northern Thailand smothered with smoke from forest and agricultural fires. The same day, the Advanced Land Imager (ALI) on NASA’s Earth Observing 1 (EO-1) satellite brought us an even closer look at one of the numerous fires.

The Culex erraticus mosquito carries eastern equine encephalitis – an uncommon but lethal disease – and it appears that the severity of the previous winter determines how soon the insects switch from feeding on birds to feeding on mammals. Severe winters seem to push the switch back, while mild winters usually meant an earlier switch.

The crew of a sea rescue helicopter caught amazing video footage of a shark feeding frenzy off the coast of Perth, Australia. The sharks are feeding on tuna, who are themselves feeding on smaller fish, while sea birds dive for the scraps.

Dubai at night ranks among the favorite areas for astronaut photography. With its collection of man-made islands in the Persian Gulf offering striking imagery from space, it’s no wonder.
