"While ChatGPT-4 correlates closely with established risk stratification tools regarding mean scores, its inconsistency when presented with identical patient data on separate occasions raises concerns about its reliability."

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."

Newly sequenced genome reveals coffee’s prehistoric origin story — and its future under climate change
"Their findings, published April 15 in Nature Genetics, suggest that Coffea arabica developed more than 600,000 years ago in the forests of Ethiopia via natural mating between two other coffee species. Arabica’s population waxed and waned throughout Earth’s heating and cooling periods over thousands of years, the study found, before eventually being cultivated in Ethiopia and Yemen, and then spread over the globe."

🇹🇷 Archaeologists find surprisingly well-preserved 8,600-year-old bread in Turkey
"The researchers concluded the bread was fermented after performing scanning electron microscope imaging. The analysis revealed air bubbles in the sample and traces of starch grains. They also found telltale chemicals known to be found in cereals and those that indicate fermentation."

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."

ChatGPT hallucinates fake but plausible scientific citations at a staggering rate, study finds
"MacDonald found that a total of 32.3% of the 300 citations generated by ChatGPT were hallucinated. Despite being fabricated, these hallucinated citations were constructed with elements that appeared legitimate — such as real authors who are recognized in their respective fields, properly formatted DOIs, and references to legitimate peer-reviewed journals."

The new science of death: ‘There’s something happening in the brain that makes no sense’
"Perhaps the story to be written about near-death experiences is not that they prove consciousness is radically different from what we thought it was. Instead, it is that the process of dying is far stranger than scientists ever suspected."
