☆ Over 10,000 pre-Columbian earthworks are still hidden in the Amazon, study finds
▼ + stars: | 2023-10-10 | by ( Mindy Weisberger | ) edition.cnn.com time to read: +7 min

Known as earthworks, they were shaped by indigenous peoples who lived in the area around 500 to 1,500 years ago. Many Amazonian earthworks that predate the arrival of European colonizers are revealed in deforested areas. Heckenberger, who was not involved in the study, has conducted research in the Brazilian Amazon since the 1990s, working with indigenous peoples of the Xingu region. These findings further demonstrate that the cultural heritage of indigenous peoples in the Americas and elsewhere is “remarkably dynamic and innovative,” he added. So the scientists also mapped 937 known earthworks, instructing the model to highlight locations for potential earthworks that shared similar topographic features with previously detected sites.

Scientists have long thought Earth's inner core is like a huge solid metal ball. It could help explain why Earth's magnetic field is so weird. Jung-Fu Lin / UT Jackson School of GeosciencesThe Earth's inner mush revealedA 2021 study had already started to question the big-iron-ball assumption. Seismic waves, they found, weren't really going through the Earth in a way consistent with a fully solid core.

☆ Mysterious ‘fairy circles’ of Namibia and Australia aren’t so rare after all, study says
▼ + stars: | 2023-09-28 | by ( Mindy Weisberger | ) edition.cnn.com time to read: +7 min

CNN —Round discs of barren dirt known as “fairy circles” look like rows of polka dots that can spread for miles over the ground. Fairy circles were previously spotted only in the arid lands of Southern Africa’s Namib Desert and the outback of Western Australia. The results showed 263 dryland locations where there were circular patterns similar to fairy circles in Namibia and Australia. Fairy circles’ mysterious originsThe study authors also compiled environmental data where circles were spotted, collecting evidence that might hint at what causes them to form. But the question “What shapes fairy circles?” is complex, and factors that create fairy circles may differ from site to site, the study authors reported.

Black holes can move through the universe at 17,500 miles per second, scientists have calculated. That's why black holes appear black. The scientists estimate the recoil speed limit for black holes is around 63 million miles per hour. They calculated that the maximum speed limit that recoiling black holes could reach was around 63 million mph. What if astronomers observe black holes that break this speed limit, recoiling at speeds greater than 63 million mph?

Researchers didn’t find the parasites in phytosaur bones or teeth; rather, they retrieved them from a nugget of fossilized feces, known as a coprolite. For example, certain fish with spiraling intestines poop out what eventually become spiral-shaped coprolites, according to Nonsrirach. “Studying the remains of parasites in coprolites is important since it provides us with rare insights into ancient parasite-host relationships,” Qvarnström said. “This event raises interesting questions about how prey animals and parasites interact with each other. It suggests that parasites may have been inside the bodies of prey before they were eaten,” Nonsrirach said.

☆ Invasive hammerhead worms are longtime New Yorkers, and they may be here to stay

Invasive hammerhead flatworms have distinctive curved heads, striped bodies ranging in color from light yellow to dark brown, and they can secrete tetrodotoxin — a neurotoxin found in puffer fish and blue-ringed octopuses. Five species of invasive hammerhead worms — four in the genus Bipalium and one in Diversibipalium — are established in North America, said Bruce Snyder, an associate professor of biology at Georgia College and State University. Today, most hammerhead worms (also known as broadhead planarians) are concentrated in the Southeast, where they favor warm, damp habitats. Bazzano Photography/Alamy Stock PhotoTo date, more than 3,000 sightings in southeastern states of just one invasive hammerhead species — Bipalium kewense — have been shared to the citizen scientist database iNaturalist. Hammerhead tetrodotoxin, which disrupts neurons’ signaling to muscles, can sicken pets if they eat the worms, according to the New Jersey Department of Environmental Protection.

Few complete fossils of this Jurassic sea turtle, named Solnhofia parsonsi, have been discovered. Today’s marine turtle species all have elongated, rigid flippers to propel them through the ocean depths. But the newly described fossil’s limbs were stumpier than those of modern sea turtles relative to its body size. An artistic reconstruction shows the extinct sea turtle in its coastal marine environment. The newly described fossil presents a far more complete view of those limbs, showing that they differed dramatically from the extremities of sea turtles alive today.

Scientists revived a 46,000-year-old worm that was living in Siberian permafrost. When they brought it back to life, the worm started having babies. When they revived it, the worm started having babies via a process called parthenogenesis, which doesn't require a mate. According to a press release, the worm spent thousands of years in a type of dormancy called cryptobiosis. This new species, however, called Panagrolaimus kolymaensis, was dormant for tens of thousands of years longer.

But researchers have found that women in foraging societies were often the ones bringing home the bacon (and other prey, too). Of the 63 foraging communities examined, 50 had records documenting women hunting. Women hunted game of all sizes, “with large game pursued the most,” the study authors reported. Women also used specialized tools: In the Philippines, for example, Agta women hunted with knives, bows and arrows, or a combination of the two weapons, depending on personal preference. In many of the groups, it seemed as though women had a more flexible approach to hunting than men did, Wall-Scheffler said.

NASAFor example, already this year a powerful solar flare caused widespread radio blackouts that disrupted high-frequency radio signals in North America, Central America, and South America. In the past, powerful solar storms have surged the Quebec power grid, causing blackouts that lasted up to eight hours.

The rats' body temperatures also dropped, though to a lesser level, up to 3.57 F (2 C). If they were able to crack the science of suspended animation, it could make space travel safer and cheaper, especially for long-haul flights like the 16-month-long round trip to Mars. A single astronaut eats about 30 kilograms (66 pounds) of food and water a week, but their consumption could drop by 75% in suspended animation, per the BBC. One avenue to induce suspended animation is to cool the body down dramatically. Nevertheless, most of the research into long-ranging suspended animation is still only being done on animals, and we're likely still a long way away from testing it on humans.

A video shows an octopus appearing to wake up from sleep in distress. The behaviour looked similar to waking up from a nightmare, scientists said. One of the study's co-authors noted that it would be difficult to study an octopus' brain activity and determine whether they actually dream. Robyn Crook, an associate professor of biology at San Francisco State University, told Live Science that the octopus' behavior could have been due to senescence, which is when an octopus' body starts to break down before death. "I don't exclude that senescence could be one of the drivers of this," Ramos told Live Science.
