"...our data suggested that the Japanese population could be best modeled by admixtures of three ancestral components (hereafter K1 to K3). K1 to K3 were the highest in Okinawa, Northeast, and West, respectively (Fig. 1D and table S4). K1 (Okinawa) component maintains a relatively stable fraction of around 12% in Hondo subgroups, except for South (which is a region adjacent to Okinawa), with a higher proportion of 22%. K2 (Northeast) and K3 (West) components showed a cline from West to East."

"What starts off as a simple desire to get a macro shot of a droplet of water freezing quickly leads George to the very edge of scientific knowledge and a shocking fact about most of the water on Earth."

The art of the bee
"As I set out to write a book on honey bee biology, I kept Humboldt as an aspirational model. Rather than write the typical biology text that reflected an excavation of levels of biological organization like taxonomy, biogeography, physiology, anatomy, etc., I built chapters around themes relating to honey bee impacts, behavior, and ecology."

"Infant mortality rates have plummeted over the last 50 years.
Globally, they’ve fallen by over two-thirds, from around 10% in 1974 to less than 3% today.
The study’s researchers estimate that 40% of this decline is due to vaccines."

Scientists are trying to get cows pregnant with synthetic embryos
"Synthetic embryos are clones, too—of the starting cells you grow them from. But they’re made without the need for eggs and can be created in far larger numbers—in theory, by the tens of thousands."
Video of sun’s surface shows solar rain, eruptions and coronal moss
"Scientists say the observations of the sun’s complex surface dynamics could help resolve the question of why the sun’s atmosphere is so much hotter than its surface – a longstanding paradox in solar physics."

"Even though it was hoped that machines might overcome human bias, this assumption often fails due to a problematic or theoretically implausible selection of variables that are fed into the model and because of small size, low representativeness, and presence of bias in the training data [5.]."

How Cambridge bred eugenics
"The term “eugenics” (from the Greek for ‘well born’) was birthed here in Cambridge by Trinity’s own Francis Galton in 1883. Galton was inspired by his cousin Charles Darwin and adapted the idea of natural selection to presuppose that the survival of the fittest had been distorted by social welfare policies."

"In most work in the history of science, the approach is to show how a particular event or outcome was the result of various social and intellectual influences. Bayesian history of science, on the other hand, focuses on the lines of evidence relevant to the historical development to see if the direction taken by an individual or group of scientists was consistent or inconsistent with the evidence at hand."

Early warning sign of extinction?
"Using a high-resolution global dataset of planktonic foraminifera fossils that’s among the richest biological archives available to science, researchers have found that environmental events leading to mass extinctions are reliably preceded by subtle changes in how a biological community is composed, acting as an early warning signal."

"We present a set of large pedigrees, reconstructed using ancient DNA, spanning nine generations and comprising around 300 individuals. We uncover a strict patrilineal kinship system, in which patrilocality and female exogamy were the norm and multiple reproductive partnering and levirate unions were common. The absence of consanguinity indicates that this society maintained a detailed memory of ancestry over generations."

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."
