Tropical Lakes on Saturn’s Moon Titan Discovered

Ant males courting mostly peacefully at Queens. Obscurer Not so with the kind of tropical Cardiocondyla: Find the wingless males that patrol the colonies, a young queen, they mate. Put it on rivals, attacking her. Because their mouth parts are good not to fight, and they hold opponents are just smear it with a substance. Workers do the rest. They kill ants marked as Sylvia Cremer of the Institute of Science and Technology (IST) has been studied in Klosterneuburg, together with researchers from the University of Regensburg.

Hope for life

Hydrocarbon lakes in the polar regions of Saturn’s moon Titan are known except the Earth, Titan is the only solid object in the solar system with liquid cycle. Methane evaporates at the surface of the moon, forms clouds and rain in the cooler polar regions again. Now, researchers are expected to analyze the infrared data probe “Cassini” but an underground methane lake in the tropical equatorial regions of the moon have discovered.

The lake is about 60 kilometers, 40 kilometers wide and at least one meter depth should be fed by methane reservoirs in the subsurface. Similarly, it should behave with the structures in near-equatorial, which were interpreted as swampy areas. This expands the regions, where life might be found on Titan.

UNESCO World Heritage Site

Archaeologists have unearthed in China more than a hundred new terracotta warriors. The life-size figures were found near the mausoleum of Emperor Qin Shi Huang in the northern province of Shaanxi. In the three years of excavations also twelve clay horses, parts of cars, weapons and tools were brought to light.

At a little “Oops” took place on Friday at the presentation of the current Chinese manned space mission Jiuquan Space Flight Station: Ping Wu spokesperson was a solar sail of the “Tian Gong 1″ model lost. The fourth China’s manned space flight is at 13 days, the longest and most complicated. For the first time a manual docking of the “magic boat” with the space module “Tian Gong 1″ (”Sky Palace”) plans are orbiting the Earth since September.

successful Start

On Saturday, the successful launch of manned spacecraft “Shenzhou-9″ in China was celebrated with an hour-long specials. On board is the first time, Yang Liu with a woman. “I am honored on behalf of hundreds of millions of Chinese women to fly into space,” said the 33-year-old pilot. Here, she shares with her colleagues Jing Haipeng (center) and Liu Wang before the rocket launch at the Jiuquan space center to see. Also for the first time, two taikonauts, as Chinese astronauts are called, go to the rendezvous in 343 km altitude in the sky palace and stay in it a total of ten days.

Planet people

In total, more than 10,000 different types of bacteria live in and on humans. It’s a real mammoth task to collect all these micro-organisms and deciphering their function. After five years of research, scientists are more than 80 research institutions had their first findings in a series of studies, two of which appear in the journal “Nature” (free full-length available). Using genetic studies, the researchers showed that all bacteria have genes in common about eight million, which can be translated into a protein.
