DolphinGemma, a large language model developed by Google, is helping scientists study how dolphins communicate — and hopefully find out what they’re saying, too.

What If We Find Nothing In Our Search For Life Beyond Earth?
What if we spend decades building advanced telescopes to search for life on other planets and come up empty-handed? A recent study led by ETH Zurich researchers including corresponding author […]

Multibeam SETI Observations Toward Nearby M Dwarfs With FAST
The search for extraterrestrial intelligence (SETI) targeted searches aim to observe specific areas and objects to find possible technosignatures. Many SETI researches have focused on nearby stars and their planets […]

Ringworlds And Dyson Spheres Can Be Stable
In his 1856 Adams Prize essay, James Clark Maxwell demonstrated that Saturn’s rings cannot be comprised of a uniform rigid body. This is a consequence of the two-body gravitational interaction […]

Could An Earth-like Alien Civilization Detect Us?
If an extraterrestrial civilization existed with Earth-like technology, would they be able to detect Earth and evidence of humanity? If so, what signals would they detect and from how far […]

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 […]

The Local Galactic Transient Survey Applied to an Optical Search for Directed Intelligence
We discuss our transient search for directed energy systems in local galaxies, with calculations indicating the ability of modest searches to detect optical Search for Extraterrestrial Intelligence (SETI) sources in […]

Projections of Earth’s Technosphere: Luminosity and Mass as Limits to Growth
Earth remains the only known example of a planet with technology, and future projections of Earth’s trajectory provide a basis and motivation for approaching the search for extraterrestrial technospheres.

COSMIC’s Large-Scale Search for Technosignatures during the VLA sky Survey: Survey Description and First Results
Developing algorithms to search through data efficiently is a challenging part of searching for signs of technology beyond our solar system.
![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 […]
