Mineral–microbe interactions play important roles in environmental change, biogeochemical
cycling of elements and formation of ore deposits. Minerals provide both beneficial (physical …

Progress in development of biophysical analytic approaches has recently crossed paths with
macromolecule condensates in cells. These cell condensates, typically termed liquid-like …

The search for definitive biosignatures—unambiguous markers of past or present life—is a
central goal of paleobiology and astrobiology. We used pyrolysis–gas chromatography …

A systematic survey of 57 different paragenetic modes distributed among 5659 mineral
species reveals patterns in the diversity and distribution of minerals related to their evolving …

It is often acknowledged that the search for life on Mars might produce false positive results,
particularly via the detection of objects, patterns or substances that resemble the products of …

The concept of a biosignature is widely used in astrobiology to suggest a link between some
observation and a biological cause, given some context. The term itself has been defined …

It has been argued that the historical nature of evolution makes it a highly path-dependent
process. Under this view, the outcome of evolutionary dynamics could have resulted in …

For more than 3.5 billion years, life experienced dramatic environmental extremes on Earth.
These include shifts from oxygen-less to overoxygenated atmospheres and cycling between …

In the last three decades, knowledge of planetary systems other than our own has increased
rapidly with the discovery of over 5,000 exoplanets (Christiansen 2022). These worlds vary …

The major revolution in modern astronomy recognizing the universe as teeming with
exoplanets, the discovery of liquid water in solar moons, and the continuing focus on Mars …
