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 ...

New study sheds light on origins of life on Earth

Addressing one of the most profoundly unanswered questions in biology, a Rutgers-led team has discovered the structures of proteins that may be responsible for the origins of life in the primordial soup of ancient Earth.

Life arose on hydrogen energy

How did the first chemical reactions get started at the origin of life and what was their source of energy? Researchers at the Heinrich Heine University Düsseldorf (HHU) have reconstructed the metabolism of the last universal ...

Darwin's magnificent mystery and the microbiome

Vanderbilt researchers are reimagining Charles Darwin's work by communicating how the origin of species might depend largely on the microbiome—the totality of bacteria, viruses, fungi and other organisms—living in or ...

The first cells might have used temperature to divide

A simple mechanism could underlie the growth and self-replication of protocells—putative ancestors of modern living cells—suggests a study publishing September 3 in Biophysical Journal. Protocells are vesicles bounded ...

Origins of life could have started with DNA-like XNAs

Nagoya University scientists in Japan have demonstrated how DNA-like molecules could have come together as a precursor to the origins of life. The findings, published in the journal Nature Communications, not only suggest ...

Lab one step closer to understanding how life started on Earth

How did life begin on Earth and could it exist elsewhere? Researchers at Simon Fraser University have isolated a genetic clue—an enzyme known as an RNA polymerase—that provides new insights about the origins of life. ...
