Origin of Life
Researchers at the Earth-Life Science Institute in Tokyo have shown through experiments that repeated freezing and thawing could have driven the growth and fusion of primitive cell-like structures on early Earth. Vesicles made with certain lipids fused into larger compartments and retained DNA more effectively during these cycles. The findings suggest icy environments played a role in life's origins.

A new mathematical analysis by Robert G. Endres of Imperial College London suggests that the spontaneous emergence of life from nonliving matter on early Earth was far less likely than previously thought. Using information theory, the research highlights the immense improbability of assembling a simple protocell from basic chemicals. The findings underscore ongoing challenges in explaining life's origins through natural processes alone.
