Before there was life on Earth, there were molecules. A primordial soup. At some point a few specialized molecules began replicating. This self-replication, scientists agree, kick-started a biochemical process that would ...

A team of engineers at Duke University have developed a method to broaden the reach of CRISPR technologies. While the original CRISPR system could only target 12.5% of the human genome, the new method expands access to nearly ...

The genetic code stored in DNA determines everything from the color of our eyes to our susceptibility to disease. This has motivated scientists to sequence the human genome and develop ways to alter the genetic code, but ...

Cells contain thousands of messenger RNA molecules, which carry copies of DNA's genetic instructions to the rest of the cell. MIT engineers have now developed a way to visualize these molecules in higher resolution than previously ...

(PhysOrg.com) -- Nobody knows quite how life originated on Earth, but most scientists agree that living cells did not abruptly appear from nonliving cells in a single step. Instead, there were probably a series of pre-cellular ...
Complex life, as we know it, started completely by chance, with small strands of molecules linking up, which eventually would have given them the ability to replicate themselves.
