CNN —A lost Caravaggio painting that was almost mistakenly sold at auction for a bargain price has gone on display at the Prado Museum in Madrid, Spain, after being rescued and restored. The oil on canvas work depicts Jesus wearing a crown of thorns with blood running down his face and onto his chest. Michelangelo Merisi da Caravaggio, better known simply as Caravaggio, is known for his visceral depictions of violence. “Ecce Homo” will be displayed at the Prado Museum until October 13. Both the previous owner and the buyer were keen for the painting to go on public display at the Prado, said Coll.

New York CNN —The Dow Jones Industrial Average is, at best, an imperfect barometer of stock market activity among a narrow band of very large US companies. It’s clunky, and too limited in scope for any Wall Street pros to pay serious attention to it. “Mention ‘the Dow’ and, to most people, that means the stock market,” said Art Hogan, chief market strategist at B. Riley Financial, in a note to CNN. It’s just an index that tracks the stock market activity of 30 large US companies, from Amazon to McDonald’s to the Walt Disney Company. Market capitalization measures the total value of a company on the stock market.

The basic chronology — Stone Age to Bronze Age to Iron Age — now underpins the archaeology of most of the Old World (and cartoons like “The Flintstones” and “The Croods”). Thomsen could well have substituted Wood Age for Stone Age, according to Thomas Terberger, an archaeologist and head of research at the Department of Cultural Heritage of Lower Saxony, in Germany. “We can probably assume that wooden tools have been around just as long as stone ones, that is, two and a half or three million years,“ he said. Of the thousands of archaeological sites that can be traced to the era, wood has been recovered from fewer than 10. The projectiles unearthed at the Schöningen site, known as Spear Horizon, are considered the oldest preserved hunting weapons.

Known as Shanidar Z, after the cave in Iraqi Kurdistan where she was found in 2018, the woman was a Neanderthal, a type of ancient human that disappeared around 40,000 years ago. The Shanidar Z facial reconstruction suggests that these differences might not have been so stark in life, Pomeroy said. Shanidar cave in Iraqi Kurdistan was first excavated in the 1950s. Neanderthals may not have honored their dead with bouquets of flowers, but the inhabitants of Shanidar Cave were likely an empathetic species, research suggests. Shanidar Z is the first Neanderthal found in the cave in more than 50 years, Pomeroy said, but the site could still yield more discoveries.

☆ Stone Age Paleo diet was not rich in meat, scientists say
▼ + stars: | 2024-04-30 | by ( Katie Hunt | ) edition.cnn.com time to read: +7 min

CNN —What did people in the Stone Age eat before the advent of farming around 10,000 years ago? Scientists analyzed chemical signatures preserved in bones and teeth belonging to at least seven different Iberomaurusians and found that plants, not meat, were their primary source of dietary protein. The evidence suggested that the Iberomaurusians consumed “fermentable starchy plants” such as wild cereals or acorns, according to the study. The work undermines the idea that a Stone Age diet was meat heavy — a rigid assumption perpetuated by present-day dietary trends like the Paleo diet. The transition to agriculture was a complex process that occurred at different times and proceeded at different rates, in different ways with different foods, in different places, Pobiner said.

WASHINGTON (AP) — Ancient stone tools found in western Ukraine may be the oldest known evidence of early human presence in Europe, according to research published Wednesday in the journal Nature. Archaeologists used new methods to date the layers of sedimentary rock surrounding the tools to more than 1 million years old. The chipped stone tools were likely used for cutting meat and perhaps scraping animal hides, he said. The very earliest stone tools of this type were found in eastern Africa and date back to 2.8 million years ago, said Rick Potts, who directs the Smithsonian Institution's Human Origins Program. “The oldest humans with this old stone tool technology were able to colonize everywhere from warm Iberia (Spain) to Ukraine, where it's at least seasonally very cold – that’s an amazing level of adaptability,” said Potts.

Archaeologists have recovered 90,000 stone tools from the site, which lies close to Ukraine’s southwestern border with Hungary and Romania. Some 90,000 stone tools made by early humans have been found at the site but no human fossils. Garba‘s colleagues measured two nuclides, aluminum-26 and beryllium-10, found in quartz grains from seven pebbles discovered in the same layer as the stone tools. The earliest human fossils unearthed in Europe are from the Atapuerca site in Spain and date back 1.1 million years, according to the study. Korolevo would have been appealing to ancient humans because it’s near the Tisza River, which leads to the Danube, and there was a readily available source of hard rock to knap stone tools, Garba said.

☆ Neanderthal glue points to complex thinking

CNN —Neanderthals likely made a type of glue from two natural compounds to help them better grip stone tools, according to a new analysis of forgotten artifacts recently rediscovered in a Berlin museum. “The fact that Neanderthals made such a substance gives insight into their capabilities and their way of thinking,” he said. The stone tools were unearthed around 1910 at a French archaeological site called Le Moustier that scientists believe Neanderthals used between 120,000 and 40,000 years ago. Their study, published Wednesday in the journal Science Advances, found that the makers of the stone tools used the adhesive to mold a handle rather than haft the tool to wood. P.

☆ To Cure to Burnout, Embrace Seasonality - The New York Times
▼ + stars: | 2024-02-16 | by ( Cal Newport | ) www.nytimes.com time to read: +1 min

For most of human existence, the pace and intensity of productivity varied widely from season to season. Following the development of agriculture around 10,000 B.C.E., the relationship between work and the seasons became even more structured, with predictably busy planting and harvesting seasons interleaved with predictably quiet winters. This led to a conception of work as something that should occur at the fullest possible intensity, without variation, throughout the year. When knowledge work arose as a major economic sector in the 20th century — the term “knowledge work” itself was coined in 1959 — it borrowed this approach from manufacturing, which was the dominant economic force of the time. Office buildings became invisible factories, with members of this growing class of workers metaphorically clocking in for eight-hour shifts, week after week, month after month, attempting to transform their mental capacities into valuable output with the same regularity as an assembly-line worker churning out automobiles.

A new book “The Naked Neanderthal” says humans were the main cause thanks to their superior weapons. Compared to early humans, Neanderthals were muscular with a prominent brow and less pronounced chin. Since humans were the final species to occupy the cave, Slimak argues it's because they'd replaced those Neanderthals by wiping them out.

☆ How head lice reveal secrets about human origins

CNN —Head lice have been constant, if unwanted, human companions for as long as our species has been around. Some 20 years ago, David Reed, a coauthor of the new study and a researcher and curator at the Florida Museum of Natural History, found that human head lice are composed of two ancient lineages, with origins predating Homo sapiens. Doing so allowed researchers to detect the hybrid lice and better capture the genetic diversity of head lice. Ascunce said she had hoped the information they gleaned might answer whether Neanderthal head lice are still around today, but the 15 genetic markers, known as “microsatellites,” that they studied in the lice nuclear DNA didn’t reveal that information. “New ongoing studies are being done using whole genome sequences from human lice, so stay tuned for more exciting research on that.”

The researchers found that, over time, the distribution of Neanderthal DNA didn’t always look as it does now. This resulted in a lower proportion of Neanderthal DNA observed in European genomes during this period. “The thing was that they had less Neanderthal ancestry so they diluted the (Neanderthal ancestry) in European populations,” Currat said.
