Earth's cousins: Upcoming missions to look for 'biosignatures' in exoplanet atmospheres Scientists have discovered thousands of exoplanets, including dozens of terrestrial—or rocky—worlds in the habitable zones around their parent stars. A promising approach to search for signs of life on these worlds is to probe exoplanet atmospheres for "biosignatures"—quirks in chemical composition that are telltale signs of life. For example, thanks to photosynthesis, our atmosphere is nearly 21% oxygen, a much higher level than expected given Earth's composition, orbit and parent star.

New technologies, strategies expanding search for extraterrestrial life Emerging technologies and new strategies are opening a revitalized era in the Search for Extraterrestrial Intelligence (SETI). New discovery capabilities, along with the rapidly-expanding number of known planets orbiting stars other than the Sun, are spurring innovative approaches by both government and private organizations, according to a panel of experts speaking at a meeting of the American Association for the Advancement of Science (AAAS) in Seattle, Washington.

Physically producing computer-generated artificial genomes to understand DNA The molecular blueprint of life is stored in DNA within the genome. The digital revolution in biology, driven by DNA sequencing, enables scientists to read the genomes of the many microbes and multicellular organisms that populate our world. Today, DNA sequences of over 200,000 microbial genomes are deposited in digital genome databases and have exponentially increased the understanding of how DNA programs living systems. Using this incredible treasure trove of molecular building blocks, bioengineers learn to sequence and synthesize long DNA molecules and to breed useful microbes with the help of computers.
