As I was organizing and arranging these links, a 4.8-magnitude earthquake hit the East Coast, so please excuse any text misalignment. This week’s highlights include stars accelerated by gravity, AIs displaying cooperative and selfish behaviors, and another round of “Would You Eat This?”
Researchers have developed multiple AIs that evolved based on repeated games, ultimately exhibiting cooperative or selfish behaviors over generations. Professor Reiji Suzuki from Nagoya University’s Graduate School of Informatics stated, “Our experiments provide fascinating insights into the evolutionary dynamics of personality traits in AI agents. We observed the emergence of both cooperative and selfish personality traits within AI populations, reminiscent of human societal dynamics.”
However, Suzuki also notes that over time, highly cooperative groups were eventually replaced by generations of egocentric models. The researchers believe the study offers insights that could contribute to the future development of beneficial AI.
Ronald Cohen, an atmospheric chemist from the University of California, Berkeley, reports that an extensive CO2-monitoring network of sensors he deployed around the Bay Area may have recorded reductions in carbon emissions caused by the adoption of electric vehicles. The network is a proof-of-concept project to monitor urban areas and identify neighborhoods affected by high emissions with previously impossible granularity.
Between 2018 and 2022, the network’s sensors recorded an overall decrease in carbon emissions of 1.8% annually, which translates to a 2.6% annual drop in vehicle emission rates. The researchers note that California has a particularly high adoption rate for electric vehicles, making it an ideal testbed for the impact of the energy transition.
