Climate-associated genetic switches found in plants

Genetic variants that can act as switches directing structural changes in the RNA molecules that code for proteins in plants have been experimentally validated in plants for the first time. The changes to RNA structure can ...

Scientists set out to map the world's genomic diversity

An international consortium of scientists has launched a new effort to create a reference genome that captures the genetic diversity of all the peoples of the world. The researchers describe the initiative, called the Human ...

The first stages of DNA evolution

One fundamental question in the field of the Origin of Life is how the first molecules of DNA replicated and evolved on the primordial Earth, more than 4 billion years ago. Before the emergence of the first cells or any other ...

Scaling laws in enzymes may help predict life 'as we don't know it'

The only references we have for "life" are the forms we know on Earth. Astrobiologists suspect that the search for alien life, and even for the origins of life on Earth, may require a broader scope. A NASA-funded team of ...
