On the trail of deepfakes, Drexel researchers identify ‘fingerprints’ of AI-generated video
"The lab’s tools use a sophisticated machine learning program called a constrained neural network. This algorithm can learn, in ways similar to the human brain, what is “normal” and what is “unusual” at the sub-pixel level of images and videos, rather than searching for specific predetermined identifiers of manipulation from the outset."
Why European Colonization Drove the Blue Antelope to Extinction
"The results of the study, which have now been published in "Current Biology", show that the species was probably adapted to a small population size and survived like this for thousands of years. However, this also made them susceptible to sudden impacts like hunting, which increased after European colonization of southern Africa."
"Our analysis of 49 coins from the North Sea zone indicates that Byzantine silver plate was the source of silver for the initial minting of the first post-Roman silver coins in England, Frisia and parts of Francia. From c. AD 750, freshly mined silver from Melle, Aquitaine, was introduced to this North Sea zone, becoming the dominant source following the coinage reforms of AD 793."

“Yet again, the dominant narrative of the bombs chugs along,” writes Naoko Wake of Michigan State University. And the victims aren’t shown.
"In this paper, we show how religiosity contributes to mental health more generally, but especially in the particular case of its effect during the Covid-19 pandemic. We find that being religious significantly reduces the negative mental health outcomes associated with Covid-19 incidence in one’s social network. This beneficial effect of religiosity on mental health, in this context, is comparable to the effect of being employed."
🇵🇱 "Results showed that the level of differentiation within Polish population is quite low, but some differences were indicated. It was confirmed that the Polish population is characterized by a high degree of homogeneity, with only slight genetic differences being observed at the regional level."
In this really interesting analytic video youtuber Meeka le Fay discussing the probability of that relying on some pretty hefty evidence in favor of this version.
