Tracking the Great Oxidation Event
|
| Topic: Origin & Evolution of Life |
01/20/13 |
| Summary: A new study shows that multicellular cyanobacteria arose much earlier than previously believed. Multicellularity developed in cyanobacteria at almost the same time as the oxygenation of Earth's atmosphere, and around one billion years earlier than eukaryotes. |

Bubbling Organics in an Ocean Vent Simulator
|
| Topic: Origin & Evolution of Life |
01/19/13 |
| Summary: Astrobiologists have built a series of glass tubes and valves with a laser and a detector system that mimics the conditions at hydrothermal vents. The system detects compounds coming from the simulated vent and will help determine if biologically important molecules are being formed. |

Ups and Downs in Biodiversity After Mass Extinction
|
| Topic: Origin & Evolution of Life |
01/06/13 |
| Summary: A new study shows that diversity of marine fauna ballooned in response to climate fluctuations following Earth's largest known mass extinction. Over time, however, climate change adversely affected biodiversity and species went extinct. |
