UGA researchers shed light on ancient origin of life
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.
ASU researchers propose new way to look at the dawn of life
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...
Studying the evolution of life's building blocks
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.
Scientists discover new clue to the chemical origins of life
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.
Avalanche of reactions at the origin of life
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.
Pumice proposed as home to the first life forms: A new hypothesis in Astrobiology journal
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.
NSF grant supports research on origin of life
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.
Transition metal catalysts could be key to origin of life, scientists report
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.
'Ancestral Eve' crystal may explain origin of life's left-handedness
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.
Charles Darwin really did have advanced ideas about the origin of life
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.
Life secret exposed: Scientists unlock mystery of molecular machine
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.
Synthetic biology yields clues to evolution and the origin of life
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.
Rensselaer opens center dedicated to the search for life in the universe
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.
Georgia Tech/Emory Center to study origin of life
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.
Origins of life
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.
Small molecule interactions were central to the origin of life
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.
Component of volcanic gas may have played a significant role in the origins of life on Earth
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.
Recooking the recipe for prebiotic soup: Scripps professor revisits the Miller experiment
A Scripps Institution of Oceanography professor and his colleague revisit the famous Miller experiment to recreate a prebiotic soup that may have been present on early Earth. The report traces the history of the experiment and highlights its significance in transforming the study of life's origin into a respectable field of inquiry.
NASA Funds New Origin Of Life Center at Rensselaer Polytechnic Institute
A new NASA-funded research center at Rensselaer Polytechnic Institute will investigate the origin of life, starting with stardust and organic molecules formed in interstellar space. The center's interdisciplinary team will explore two hypotheses on the formation of life's building blocks.
