Giving ancient life another chance to evolve

It’s a project 500 million years in the making. Only this time, instead of playing on a movie screen in Jurassic Park, it’s happening in a lab at the Georgia Institute of Technology. Using a process called paleo-experimental evolution, Georgia Tech researchers have resurrected a 500-million-year-old gene from bacteria and inserted it into modern-day Escherichia coli(E. coli) bacteria. This bacterium has now been growing for more th Read more...

From toxicity to life: Arsenic proves to be a building block

Arsenic – an element that triggers death for most Earthly life forms – is actually allowing for a bacterium to thrive and reproduce. In a study that may prompt the rewriting of textbooks, a team of astrobiologists and chemists has found the first known living organism that can use arsenic in place of phosphorus in its major macromolecules. The new findings, published in the Dec. 2 Science Express, could redefine origins of life re Read more...
