Hot Topic Origins Origin & Evolution of Life
 
What is Life?
Topic: Origin & Evolution of Life
03/19/11
Summary: Systems biology studies how living organisms emerge from interactions of the individual elements that compose cells. The field is just beginning to come to prominence, but could provide important advances in understanding life's origins.

New Yeast Species Looks Like Saturn
Topic: Origin & Evolution of Life
03/18/11
Summary: A new species of yeast has been discovered in the Maquipucuna cloud forest nature reserve in Ecuador. The finding provides new information about the diversity of life, and could help in developing technologies for producing 'bio-energy' in the future.

Earth's Sixth Mass Extinction
Topic: Origin & Evolution of Life
03/06/11
Summary: Earth may be on the brink of a mass extinction on the scale of the five global mass extinctions that have occurred during the past 540 million years. The researchers believe that a modern global mass extinction would be the result of climate change and human activities, but they also believe it is not to late to stop it.

Reviving 100-Year-Old Diatoms
Topic: Origin & Evolution of Life
03/02/11
Summary: Scientists have revived 100-year-old spores that had laid buried and inactive in sediments at the bottom of the sea. The study provides a glimpse into diatom communities that go back 40,000 generations.

Clay-Armored Bubbles may have Formed First Protocells
Topic: Origin & Evolution of Life
02/22/11
Summary: Scientists have demonstrated that semipermeable vesicles can form from inorganic clay. Such vesicles might have been perfect containers for the first primitive cells.

How Nature's Patterns Form
Topic: Origin & Evolution of Life
02/20/11
Summary: By studying how patterns arise in various systems, a mathematician may show how biological forms are controlled by the laws of physics and not just evolution. The research could provide new information about the history of life on Earth.

New Fossil Discovery Sheds Light on Permian Extinction
Topic: Origin & Evolution of Life
02/18/11
Summary: Discoveries at a new fossil site in China are filling gaps in our understanding of how life recovered after the greatest mass extinction known in Earth's history.

Not All Dinos Died at Once
Topic: Origin & Evolution of Life
02/18/11
Summary: Researchers have discovered a fossilized dinosaur bone that raises questions about the theory that the age of dinosaurs ended between 65.5 and 66 million years ago. The discovery could change our understanding of the timeline of life's evolution on Earth.

Solar-Powered Hornets
Topic: Origin & Evolution of Life
02/12/11
Summary: Scientists have demonstrated how a member of the animal kingdom is able to convert the Sun's energy into electric power. The discovery highlights a previously unknown connection between the Sun and life on Earth, and shows yet another unique way in which organisms can adapt to survive in their natural environments.

DigiMorph: Bringing Fossils to Life
Topic: Origin & Evolution of Life
02/10/11
Summary: A new technique is helping scientists view precious fossils and share them with researchers all over the world. The technology could aid astrobiologists in their work to understand life's origin, evolution and history on Earth.
