Astronomy: A Search for Martian Life -- And a New Name for Pluto

After a couple of miscues, the Phoenix Mars Lander finally filled its tiny scientific oven with Martian soil last week, and scientists were expected to begin analyzing it to determine whether, among other things, the soil contains organic compounds.

Meanwhile, NASA launched its Gamma-ray Large Area Space Telescope (GLAST) last week on a five- to 10-year mission in Earth orbit. It will pick up where the Compton Gamma Ray Observatory left off, but with better technology. Its particle detectors are much more sensitive and should provide the best look yet into the high-energy universe.

In other news, cosmologists speculate that structures larger than the visible universe may be responsible for a strange pattern seen in the Big Bang's afterglow. If confirmed, the structures could provide important information about the universe's early history.

Cosmologists are also pondering why the pattern of radiation left over from the Big Bang looks different in different regions of the sky. Several theories are being proposed for a "lopsided" universe.

And, finally, what was formerly known as the ninth planet in the solar system will henceforth be known as a "plutoid," according to the International Astronomical Union. That will be the official designation of all small, nearly spherical objects orbiting beyond Neptune.

PODCAST & VIDEO: Engineering Around Extreme Events

Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
