Projections Of Earth’s Technosphere: Scenario Modeling, Worldbuilding, And Overview Of Remotely Detectable Technosignatures
This study uses methods from futures studies to develop a set of ten self-consistent scenarios for Earth’s 1000-year future, which can serve as examples for defining technosignature search strategies.

An Exploratory Framework for Future SETI Applications: Detecting Generative Reactivity via Language Models
We present an exploratory framework to test whether noise-like input can induce structured responses in language models.

Quantifying The Fermi Paradox Via Passive SETI: A General Framework
In this paper we consider the extent to which a lack of observations from SETI may be used to quantify the Fermi paradox.

Earth Detecting Earth: At What Distance could Earth’s Constellation of Technosignatures be Detected with Present-day Technology?
The field of the Search for Extraterrestrial Intelligence (SETI) searches for “technosignatures” that could provide the first detection of life beyond Earth through the technology that an extraterrestrial intelligence (ETI) […]

Whale Song Has Structure Similar To Human Language
Humpback whale song is a striking example of a complex, culturally transmitted behavior, but up to now, there was little evidence it has language-like structure. Human language, which is also […]
![Semantic thresholds. Semantic Information identifies “semantic thresholds” where only specific mutual information between an agent and its environment impacts viability. (a) The foundational study [14] introduced this concept through counterfactual simulations assessing viability as information is scrambled. (b) Forager models [40] demonstrated such thresholds by adding noise to food detection sensors, revealing a peak in viability per bit of information at the threshold. (c) Similar thresholds appear in biosphere models like Daisy-World, responding to stellar forcing [41]. -- cond-mat.soft](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/01/The-Physics-of-Life-Exploring.png?resize=1200%2C720&ssl=1)

The Physics of Life: Exploring Information as a Distinctive Feature of Living Systems
This paper explores the idea that information is an essential and distinctive feature of living systems. Unlike non-living systems, living systems actively acquire, process, and use information about their environments […]

Non-Living Intelligence: Cracking The Code For Materials That Can Learn
It’s easy to think that machine learning is a completely digital phenomenon, made possible by computers and algorithms that can mimic brain-like behaviors.
