A new study suggests that so-called emergent abilities actually develop gradually and predictably, depending on how you measure them.
“New surveys of the sky provide groundbreaking opportunities to search for technosignatures coordinated with supernovae.” said Bárbara Cabrales.
Are we alone in the universe? This longstanding question is what the SETI (Search for Extraterrestrial Intelligence) Institute has been trying to answer for decades as its vast array of radio telescopes continues to scan the heavens for signs of intelligent life beyond Earth, also known as technsigatures. Now, a team of researchers led by the Berkeley SETI Research Center have developed the SETI Ellipsoid with the hope it will offer greater opportunities for identifying technsigatures from intelligent civilizations throughout the cosmos. These findings were recently published in The Astronomical Journal and hold the potential to help scientists better understand the necessary criterion for finding intelligent life beyond Earth.
For the study, the researchers began by hypothesizing that intelligent civilizations could use what’s known as a Schelling point (more commonly called a focal point) during supernovae events as an opportunity to broadcast coordinated signals announcing their existence to the cosmos. The researchers then compared this criterion to data from NASA’s TESS (Transiting Exoplanet Survey Satellite) spacecraft, finding the criterion matched 5 percent of TESS data. After searching through the data using their new SETI Ellipsoid method, the team identified zero technosignatures, but noted this new method could provide unique opportunities for identifying technosignatures in the future.

Legume plants have the unique ability to interact with nitrogen-fixing bacteria in the soil, known as rhizobia. Legumes and rhizobia engage in symbiotic relations upon nitrogen starvation, allowing the plant to thrive without the need for externally supplied nitrogen.
Symbiotic nodules are formed on the root of the plant, which are readily colonized by nitrogen-fixing bacteria. The cell-surface receptor SYMRK (symbiosis receptor-like kinase) is responsible for mediating the symbiotic signal from rhizobia perception to formation of the nodule. The activation mechanism of the receptor was until recently unknown.
In this study, appearing in Proceedings of the National Academy of Sciences, researchers have now identified four essential phosphorylation sites that act as the catalyst for the symbiotic relationship between legume plants and nitrogen-fixing bacteria. The initial steps of the symbiotic pathway at the cell surface are well characterized; however, understanding of how the signal is relayed downstream has eluded the research field for years.

Jupiter and its moon are a rarely considered prospect for colonization, but potentially the ripest opportunity for it in the solar system. In this episode of the Outward Bound series we will examine the options for colonizing each of Jupiter’s primary moons and even discuss ways to colonize the giant planet itself.
