Physical laws—such as the laws of motion, gravity, electromagnetism, and thermodynamics—
codify the general behavior of varied macroscopic natural systems across space and time …

The concepts that we generally associate with the field of data science are strikingly
descriptive of the way that life, in general, processes information about its environment. The …

We offer a detailed description of our previously published new concept of the evolution of
the biosphere as an integral system of its states over time, united by development trends …

We propose a measure, the joint differential entropy of eigencolors, for determining the
spatial complexity of exoplanets using only spatially unresolved light-curve data. The …

We survey some of the philosophical challenges and pitfalls within origins research. Several
of these challenges exhibit circularities, paradoxes, or anthropic biases. We present origins …

Geological evidence and atmospheric and climate models suggest habitable conditions
occurred on early Mars, including in a lake in Gale crater. Instruments aboard the Curiosity …

Early Mars was likely habitable, but could life actually have started there? While cellular life
emerged from prebiotic chemistry through a pre-Darwinian selection process relevant to …

What is an organism? In the absence of a fundamental biological definition, what constitutes
a living organism, whether it is a unicellular microbe, a multicellular being or a multi …

While fields like Artificial Life have made huge strides in quantifying the mechanisms that
distinguish living systems from non-living ones, particular mechanisms remain difficult to …

Since the notion of the Anthropocene entered the discourse of environmental humanities, it
has prompted multiple conceptual innovations. This paper focuses on one such case: the …
