Abstract A new method for monitoring hydrothermal reactions on the millisecond time scale has been developed using a micro-tube flow reactor. The system was designed based on a high-pressure pump, a sample-loop injector, a narrow-bore size capillary, a cooling bath, back-pressure tubing, and a sampling port.

NASA's RNA World Experiments and the Matter World Hypothesis: A Comprehensive Critique
The RNA World Hypothesis (RWH) posits that self-replicating RNA molecules were the primary precursors to life, functioning as both genetic material and catalysts in Earth’s prebiotic environment. Supported by NASA’s Astrobiology Program, RWH experiments have simulated early Earth conditions, such as tidal pools (pH 6-6.5, 25-50°C, 0.5 M NaCl) and ...openaire +2 more sources

The RNA World Hypothesis (RWH), which posits RNA as the sole primordial molecule driving life’s origin, faces significant challenges due to RNA’s chemical instability, limited catalytic capacity, and inability to form stable protocells. In contrast, the Matter World Hypothesis (MWH) proposes that life emerged from synergistic interactions among RNA ...

The Matter World Hypothesis (MWH), introduced by Reza Hashemi in 2025, offers a compelling alternative. MWH envisions life’s origins as a collaborative effort among RNA, DNA, peptides, lipids, and catalysts (e.g., montmorillonite clay, Zn²⁺ ions) in a dynamic “matter soup.” This synergistic network, operating in diverse prebiotic environments like ...

RNA-DNA-Protein-Environment Model: A Simulation Study Challenging the RNA World Hypothesis
The RNA World Hypothesis posits that RNA alone initiated life through self-replication and catalysis. However, its fragility under prebiotic conditions—such as UV radiation, temperature fluctuations, and reactive oxygen species—casts doubt on its sufficiency.openaire +1 more source

The RNA World Hypothesis (RWH) posits that RNA alone initiated life, serving as both genetic material and catalyst. However, RNA’s chemical instability, poor catalytic efficiency, and high mutation rates challenge its evolvability. The Matter World Hypothesis (MWH) proposes that life emerged from synergistic interactions among RNA, DNA, peptides ...

The RNA World hypothesis posits that RNA alone could sustain early life as both genetic and catalytic molecule. We challenge this by simulating a minimal 170-nt RNA protocell (70 nt functional + 100 nt rRNA; 30% A, 30% G, 20% C, 15% U, 5% inosine/pseudouridine; ΔΔG -8.5 to -9.5 kcal/mol) in hydrothermal vents (80 ± 15°C, pH 6.0 ± 0.5, oxidative stress ...

The RNA World Hypothesis (RWH) posits that RNA alone initiated life, acting as both genetic material and catalyst. However, RNA’s chemical instability and limited catalytic efficiency challenge this view. The Matter World Hypothesis (MWH) proposes that life emerged from synergistic interactions among RNA, DNA, peptides, lipids, and catalysts in diverse
