One of humanity’s most profound questions is whether life exists beyond Earth — and if so, what forms it might take. For ...

Their findings, appearing in Nature Chemistry, suggest that environmental factors played a key role in shaping the molecular complexity needed for life to emerge. To simulate early Earth ...

The earliest days of Earth held secrets that scientists are still trying to uncover. One of the greatest mysteries is how ...

this discovery gives scientists insight into the potential chemistry of life on other planets. "When we look for signs of life—either on the early Earth or on other planets—we base the search ...

This prebiotic Earth, however, was filled with a wide array of abiotic organic molecules derived from its early environment ... can uptake salts can provide insights into the relevant functions ...

Using computational modeling, a team of scientists explored how working backwards from modern biochemistry could help map out how simple, non-living chemicals present on early Earth gave rise to ...

For decades scientists have theorized that life on Earth began in the oceans. The chemistry, however, remained an enigma. Raw amino acids — something that meteorites delivered to early Earth daily — ...

and were probably “ubiquitous” on early Earth. But the experimental setup can be used to test other questions about early chemistry on the planet. Mast is hoping to next create a network of ...

The pathway, which has evaded scientists for decades, involved relatively simple molecules probably present on early Earth that combined ... Why do the rules of chemistry mean life here looks ...

Such networks, which would have been common on the early Earth, could have provided a kind ... Can we shape or stop evolution? New insights into nature are providing surprising answers, and ...

Bringing together experts in biology, geology, geochemistry, and genomics, the paper details the journey of Earth's early life forms ... study incorporated the chemistry of these rocks and the ...

A new study explores how complex chemical mixtures change under shifting environmental conditions, shedding light on the prebiotic processes that may have led to life on Earth. In the Painted Desert ...
