Hot Topic Origins Origin & Evolution of Life
 
How Simple Life Got Complicated?
Topic: Origin & Evolution of Life
08/13/11
Summary: New research shows how single-celled organisms may have initially banded together into multicellular groups.

A Simple Solution to Life's Origin
Topic: Origin & Evolution of Life
08/12/11
Summary: A new study shows how a relatively simple combination of naturally occurring sugars and amino acids offers a plausible route to the building blocks of life.

The Riddle of Regeneration
Topic: Origin & Evolution of Life
08/11/11
Summary: Researchers have demonstrated that flatworms are able to regenerate their excretory system from scratch. The findings could provide clues about the evolutionary origin of mammalian kidneys and the processes behind organ maintenance and regeneration.

The Role of Fungi in the P-T Extinction
Topic: Origin & Evolution of Life
08/07/11
Summary: A new study shows that the demise of the world's forests 250 million years ago was likely accelerated by tree-killing fungi triggered by global climate change.

SAR11 and the Evolution of Mitochondria
Topic: Origin & Evolution of Life
07/31/11
Summary: New research shows that mitochondria share an ancestor with an abundant marine microorganism.

Barley Bespeaks of Life on Land
Topic: Origin & Evolution of Life
07/30/11
Summary: The chance discovery of agenetic mutation in wild barley is changing knowledge about the evolution of life on land.

Are Cancers Newly Evolved Species?
Topic: Origin & Evolution of Life
07/29/11
Summary: A group of researchers recently described a new theory that carcinogenesis is another form of speciation.

The 7th and 8th Bases of DNA
Topic: Origin & Evolution of Life
07/25/11
Summary: Researchers have discovered the seventh and eight base pairs that can be used to build DNA.

Batman Bacteria
Topic: Origin & Evolution of Life
07/20/11
Summary: Scientists have identified the complex sequence of movements involved in the 'twitching' motility used by some bacteria. The study provides insight into evolutionary mechanisms that allow simple organisms to adapt to changing conditions in their environment.

Rewriting the Book of Life
Topic: Origin & Evolution of Life
07/19/11
Summary: Researchers have developed technologies that could be used to rewrite the genetic code of living cells. This could enable cells to build proteins not found in nature, or bacteria that are resistant to viral infection.
