First 3-D pterosaur eggs found with their parents

Researchers have discovered the first three-dimensionally preserved pterosaur eggs in China. The eggs were found among dozens, if not hundreds, of pterosaur fossils, representing a new genus and species (Hamipterus tianshanensis). The discovery reveals that the pterosaurs -- flying reptiles with wingspans ranging from 25 cm to 12 m -- lived together in gregarious colonies.

Big Crash Theory: Moon May Be Child of Earth

The Moon might be the child of the Earth and another small planet, scientists say, claiming they have evidence of oxygen isotopes in Apollo moon samples. The team of German researchers studied several lunar meteorites and three basalt rock samples brought back by the crews of the Apollo 11, Apollo 12 and Apollo 16 missions some forty years ago, which they say contain evidence of a Mars-sized planet called Theia having crashed into Earth and created the moon.

Due to a new technique, the team detected a chemical difference between Earth and moon rocks, which according to their theory, proves that moon rocks contain traces of a body that clashed with the Earth.Most computer models esimate that between 70 percent and 90 percent of the moon is that mysterious Theia, so it should have a slightly different chemical makeup than Earth.

Computer scientists develop tool to make the Internet of Things safer

Computer scientists have developed a tool that allows hardware designers and system builders to test security -- a first for the field. There is a big push to create the so-called Internet of Things, where all devices are connected and communicate with one another. As a result, embedded systems -- small computer systems built around microcontrollers -- are becoming more common. But they remain vulnerable to security breaches. Some examples of devices that may be hackable: medical devices, cars, cell phones and smart grid technology.

Common house ants form super colonies, prosper in Urban Settings

One of the most common house ant species might have been built for living in some of the smallest spaces in a forest, but the ants have found ways to take advantage of the comforts of city living.

Grzegorz Buczkowski, a Purdue University research assistant professor of entomology, found that odorous house ant colonies become larger and more complex as they move from forest to city and act somewhat like an invasive species. The ants live about 50 to a colony with one queen in forest settings but explode into supercolonies with more than 6 million workers and 50,000 queens in urban areas.

Iran to put 3 satellites into orbit this year

An Iranian aerospace official says the country plans to launch three indigenously designed and manufactured satellites into orbit during the current Iranian calendar year (started March 21, 2014).

Deputy Head of Iran Space Agency (ISA) Hamid Fazeli said on Saturday that Sharif Sat, Tadbir (Prudence) and Fajr (Dawn) satellites will be lifted into space before the end of the year.

He went on to say that the satellites are ready to be launched into orbit and that they will be lifted into space in due time.
