This discovery provides new insights into the ideal conditions for life to emerge, with implications for various hypotheses and experiments.
Researchers from UCL, Harvard and Massachusetts General Hospital suggest a single chemical mechanism for forming both purine and pyrimidine nucleotides. They demonstrate that these molecules can be assembled on the same sugar scaffold to form RNA, providing a solution to a long-standing challenge in understanding the origins of life.
Dirk Schulze-Makuch's research suggests that the evolution of organisms functionally similar to plants or animals on Earth will naturally follow given enough time and a suitable environment. He found that critical evolutionary adaptions such as photosynthesis and multicellularity arose multiple times in different organisms.
A new model suggests that template-assisted ligation could have enabled the leap from monomers to self-replicating polymer chains in primordial soup. The model proposes a cycle between 'day' and 'night' phases, driven by environmental changes, where polymers join together to form longer chains via template-assisted ligation.
Researchers at Scripps Research Institute have devised an enzyme with unique properties that may have contributed to the origin of life on Earth. The new ribozyme works by knitting together a 'copy' strand of RNA using an original template, with the ability to make copies of its own left-hand mirror image.
Researchers from the University of Southern Denmark discover information strings with peculiar properties that can replicate quickly and efficiently, leading to a self-organizing autocatalytic network. This mechanism has potential value for developing technology based on living processes, such as self-healing devices.
A reconstructed ancient ocean revealed spontaneous chemical reactions that could have produced crucial organic molecules for life.

Researchers at the Georgia Institute of Technology and NASA have developed a simplified approach to the Miller-Urey experiment, which aims to recreate the conditions under which organic molecules could have formed on early Earth. The study successfully forms amino acids, building blocks of life, under primitive Earth conditions.
Scientists have developed novel methods to identify thousands of molecules formed during hydrogen cyanide reactions in laboratory experiments. These approaches confirm the potential for these techniques in future chemical analyzes, including exploring autocatalytic cycles and understanding life's origins on Earth and other planets.
Researchers at TSRI will receive $2 million in funding to investigate the origins of life on Earth, focusing on chirality and replicating systems.
University of Georgia researchers discovered essential genes in archaea that shed light on the history of microorganisms and the origins of life. The study found unique DNA synthesis systems, essential genes necessary for methane production, and insights into cell formation.
Researchers at Arizona State University propose a novel approach to the origins of life, focusing on the 'software' - information content. The study suggests that life is characterized by its unique use of information, providing a roadmap for identifying criteria for emergence. This approach moves away from chemical-based approaches, w...
A Michigan State University professor is exploring the origin of life at its fundamental building blocks, finding connections between bacteria and humans through molecular complementarity. This shared set of modules may hold the key to understanding evolution and explaining diseases like diabetes.
Researchers at the University of York have successfully recreated a process that could be responsible for the origin of carbohydrates in life. By using simple left-handed amino acids as catalysts, they produced predominantly right-handed sugars, shedding light on how these building blocks came to dominate nature.
Researchers around Günter Wächtershäuser demonstrate a self-generating metabolism in hot water, which leads to the formation of genetic material and the first cells. This discovery suggests that life arose billions of years ago in volcanic-hydrothermal flow ducts.
A team of researchers suggests that pumice, a glassy and porous rock, could have given rise to early life forms. The authors propose four properties of pumice that would enable it to support the emergence of life and create an ideal habitat for microorganisms.
Researchers led by Virginia Tech biochemist Bob White are studying Methanocaldococcus jannaschii to understand the origin of life. They have found that this ancient organism uses a primitive metabolic process, which could help unravel the mystery of how life first emerged on Earth.
Researchers suggest molecular structures involving transition metals could catalyze the synthesis of basic biochemicals, leading to the origin of life. The model proposes that simple transition metal-ligand complexes in hydrothermal ocean vents catalyzed reactions that gave rise to more complex molecules.
Researchers found conditions on primordial Earth could easily form left-handed aspartic acid crystals, leading to exclusive preference for left-handed amino acids in life forms. This discovery may help resolve the origin of life's left-handedness mystery.
Darwin's private correspondence and notebooks reveal a detailed understanding of evolutionary processes underlying biodiversity. Despite mentioning 'Creator' in The Origin of Species, Darwin was troubled by the origin of life problem and had an advanced idea on its solution.
A new theory proposes that a universal molecular machine, the ribosome, self-assembled based on basic chemical principles. This breakthrough explains how such complex structures emerge in nature, shedding light on the origins of life on Earth.
Biochemist David Deamer explores the molecular self-assembly processes that led to the first protocells nearly 4 billion years ago. He proposes a combinatorial chemistry approach to understanding how life began, suggesting complex systems of molecules assembled on early Earth.
The New York Center for Astrobiology will investigate the origins of life on Earth and conditions that lead to habitable planets. Researchers aim to detect evidence of current or past life on Mars, building on NASA missions.
Researchers at The Origins Project aim to understand which molecules and chemical reactions led to the emergence of life on Earth. They will investigate the formation of lifelike polymers and their evolution into life as we know it.
Scientists from the University of Miami's Rosenstiel School have developed an approach to investigate ocean reefs, which are considered the core of most living organisms. The new study has shed light on how stromatolites form and offers a new way to explore the origins of these living records.
Shapiro's theory suggests that small molecule interactions were central to the origin of life, rather than self-replication. He introduces the concept of a 'driver' reaction linked to a free energy source to convert an unorganized mixture into a self-regulated metabolic network.
Researchers have found that carbonyl sulfide forms peptide bonds spontaneously, addressing a long-standing question in the origin of life. The discovery suggests that this chemical component may have played a significant role in the emergence of life on Earth.
