It had been previously thought that the Poverty Point earthworks in northeastern Louisiana were inhabited some 3,500 years ago by a complex, hierarchical society ruled as a chiefdom, but traces of long-term dwellings and burials have not been uncovered at the site. According to a statement released by Washington University in St. Louis, archaeologists T.R. Kidder, Olivia Baumgartel, and Seth Grooms suggest that Poverty Point was used as a meeting place by egalitarian hunter-gatherers who lived all over the Southeast and the Midwest. “When these earthworks were being constructed, the Southeast was prone to severe weather and massive floods,” Kidder...

Neanderthals may have fashioned ocher tools for drawing and marking surfaces, according to a Phys.org report. Francesco d'Errico of the University of Bordeaux and his colleagues analyzed the composition and surface markings on 16 pieces of ocher unearthed at Neanderthal sites in Crimea and Ukraine with scanning electron microscopes and portable X-ray scanners. The study determined that one of the pieces of yellow ocher had been scraped into a crayon-like shape, and that its tip had been repeatedly resharpened and reused. Evidence of polishing, engraving, grinding, and sharpening were detected on another two pieces of ocher. The researchers concluded that...

Explanation: What created this unusual space sculpture? Stars. This unusual system of swirls and shells, known as Apep, was observed in unprecedented detail by NASA’s James Webb Space Telescope in infrared light in 2024. Observations indicate that the unusual shape originates from two massive Wolf-Rayet stars orbiting each other every 190 years with each close passes causing a new shell of dust and gas to be expelled. Holes in these shells are thought to be caused by a third orbiting star. This stellar dust dance will likely continue for hundreds of thousands of years, possibly ending only when one of...

Eli Lilly reached a $1 trillion market capitalization on Friday, the first health-care company in the world to join the exclusive club dominated by tech firms. The drugmaker’s stock inched about 1% higher Monday, trading above the $1 trillion threshold. Eli Lilly is the second nontechnology company to reach that market cap milestone in the U.S. after Warren Buffett’s Berkshire Hathaway . The company’s rise came as shares of its chief rival in the GLP-1 drug space, Novo Nordisk , tumbled about 6% in U.S. trading Monday. While Novo Nordisk’s stock fell after disappointing Alzheimer’s trial results, the drugmaker’s market...

Explanation: That big, bright, beautiful Full Moon you watched rise on the night of October 6 was the Harvest Moon. Famed in festival, story, and song, Harvest Moon is just the traditional name of the full moon nearest the time of the northern hemisphere's autumnal equinox. According to lore the name is a fitting one. Despite the diminishing daylight hours, as the growing season drew to a close in the north, farmers could harvest crops by the light of a full moon shining on from dusk to dawn. Later this year than usual, in 2025 October's Harvest Moon was also...

Popular Science reports that Peruvian authorities announced several new discoveries from the Caral civilization site of Vichama, including a one-of-a-kind statuette. The site was a major agricultural and fishing hub that was among the network of Caral urban centers that flourished around 5,000 years ago. Archaeologists have uncovered about 30 major structures, including public buildings, residential houses, and ceremonial plazas. One exceptional object that was recently uncovered was a 3,800-year-old clay figurine painted red and black that depicts two frogs conjoined at their hind legs. Scholars believe the amphibians played an important symbolic role in Caral culture, as they were...

According to a statement released by Eötvös Loránd University, an international team of researchers led by Tamás Hajdu of Eötvös Loránd University has identified a skeleton unearthed on Budapest's Margaret Island as the remains of Duke Béla of Macsó. The thirteenth-century duke is known to have been the maternal grandson of King Béla IV of Hungary and a member of the Scandinavian Rurik dynasty, which ruled Kievan Rus, on his father's side. Austrian historical accounts attest that the duke was assassinated in November 1272, and that his body was recovered by relatives and buried in a monastery on Margaret Island....

Explanation: How far can you see? Everything you can see, and everything you could possibly see, right now, assuming your eyes could detect all types of radiations around you -- is the observable universe. In light, the farthest we can see comes from the cosmic microwave background, a time 13.8 billion years ago when the universe was opaque like thick fog. Some neutrinos and gravitational waves that surround us come from even farther out, but humanity does not yet have the technology to detect them. The featured image illustrates the observable universe on an increasingly compact scale, with the Earth...

A massive dry fracture has just opened on Mount Etna -- and scientists are now raising the alert level. This newly discovered fissure on the southeast wall is not releasing lava, but that doesn't make it safe. In fact, this type of "silent cracking" is often a sign of deep internal pressure, structural movement, or early-stage volcanic instability. In today's Geology Watch report, we break down the footage shared by Pio Andrea Peri and the latest update from INGV, which has now issued an F1 Alert Status -- indicating a high probability of lava fountains and increased volcanic activity at...

Explanation: What powers are being wielded in the Wizard Nebula? Gravitation strong enough to form stars, and stellar winds and radiations powerful enough to create and dissolve towers of gas. Located only 8,000 light years away, the Wizard nebula, featured here, surrounds a developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small...

Disgraced ex-TV anchor Stephanie Hockridge will spend the next ten years behind bars for her role in a multi-million-dollar COVID fraud scheme – serving her time in the same cushy lockup as notorious sex trafficker Ghislaine Maxwell. The 42-year-old, a former Phoenix TV anchor turned entrepreneur, was sentenced in Texas federal court Friday and ordered to cough up nearly $64 million in restitution for the bogus Paycheck Protection Program loans she helped secure during the height of the pandemic, the Justice Department announced. Hockridge, found guilty in June of conspiracy to commit wire fraud, will report to prison on Dec....

In the same time period that the United States built the overdue and over-budget Plant Vogtle, China built 13 reactors of similar scale, and has 33 more on the way

Explanation: Seen to the left of Saturn's banded planetary disk, small icy moons Dione and Rhea are caught passing in front of the gas giant's extensive ring system in this sharp telescopic snapshot. The remarkable image was recorded on November 20, when Saturn's rings were nearly edge-on when viewed from planet Earth. In fact, every 13 to 16 years the view from planet Earth aligns with Saturn's ring plane to produce a series of ring plane crossings. During a ring plane crossing, the interplanetary edge-on perspective makes the thin but otherwise bright rings seem to disappear. By November 23rd Saturn's...

Explanation: Now a second supernova in this same galaxy is repeating. The cause is the gravitational lens effect of a massive foreground cluster of galaxies (MACS J0138) -- it creates multiple images of a perfectly aligned background galaxy (MRG-M0138). What's particularly interesting is that this background galaxy has young stars that keep blowing up. And images of each supernova explosion keep coming to us multiple times through different paths through the cluster. The original lensed supernova set, shown in the rollover, is called Requiem and was first seen by the Hubble Space Telescope in 2016. This second lensed supernova set...
