Ancient temple ruins discovered in Andes pull back curtain on lost society after 1,000 years
Known as the Tiwanaku, the society lived in modern-day Bolivia near the southern shores of Lake Titicaca – the highest navigable lake in the world – before their mysterious disappearance more than 1,000 years ago.
People had first started to live in the region around 10,000 years ago, according to University of California at Berkeley archaeologist Dr. Nicola Sharratt. As many as 20,000 people came to reside in the area. Skilled stoneworkers, the Tiwanaku were widely considered to be a precursor of the Inca empire and one of the earliest examples of civilization in the Andes mountains.
'Their society collapsed sometime around 1,000 CE and was a ruin by the time the Incas conquered the Andes in the 15th century,' José Capriles, an associate professor of anthropology at Penn State University, said in a statement. 'At its peak, it boasted a highly organized societal structure, leaving behind remnants of architectural monuments like pyramids, terraced temples and monoliths, most of which are distributed in sites around Lake Titicaca and, while we know Tiwanaku's control and influence extended much further, scholars debate how much actual control over distant places it had.'
Capriles was the lead author of the international study detailing the findings published this week in the journal Antiquity.
The temple is called 'Palaspata,' which was the native name for the area. Palaspata is located on a hill, approximately 130 miles to the south of the Tiwanaku's established historical site. The area was previously known to indigenous farmers, but had never been explored in depth by researchers.
After noticing a strange plot of land with four sides, they turned to technology to learn more. They snapped and compiled satellite images of the site, and also took pictures using cameras aboard unmanned aerial vehicle flights. Then, they used the photos to construct a three-dimensional approximation of the Palaspata and its surrounding landscape. About the size of a city block, the complex includes 15 quadrangular enclosures arranged around a rectangular inner courtyard.
Its composition, the authors said, suggested that it was used to perform rituals following the solar equinox: a bi-annual moment when the sun is positioned directly above the equator. But, it likely was not solely used for religious purposes.
Much about the Tiwanaku civilization remains unknown, but Palaspata would have been in an advantageous trade spot, according to Capriles. Many people traded and built monuments throughout the mountains. This temple connected three main trade routes, including the highlands, a high-altitude plateau, and the Andean valleys of Cochabamba.
'Most economic and political transactions had to be mediated through divinity, because that would be a common language that would facilitate various individuals cooperating,' he explained.
On the surface of the ruins of Palaspata, the scientists found fragments of 'keru' cups, which were used for drinking a traditional maize beer called 'chicha' during agricultural feasts and celebrations. The maize was cultivated in the Cochabamba valleys.
The researchers had worked with the Bolivian Ministry of Cultures, Decolonization, and Depatriarchalization to export samples of the ruins, which were dated at the Penn State's Institute of Energy and the Environment Radiocarbon Dating Lab.
The city is now working with state and national authorities to help properly protect and preserve the site.
'With more insight into the past of this ancient site, we get a window into how people managed cooperation, and how we can materially see evidence of political and economic control,' Capriles said. 'There's still so much to discover that we don't know about, and that could be hiding in plain sight. It just requires opening your eyes to see what's out there.'

Eating this surprising fruit might be the key to getting a better night's sleep
Eating one avocado a day might be the key to a better night's sleep. Adults who included the fruit -- and yes, it's a fruit -- in their daily diet over the course of just six months reported better quality sleep compared to people who consumed fewer than two avocados each month, researchers said. 'Sleep is emerging as a key lifestyle factor in heart health, and this study invites us to consider how nutrition — and foods like avocado — can play a role in improving it,' Dr. Kristina Petersen, an associate professor of nutritional sciences at Penn State University, explained. The recent findings on sleep were tied to avocado's beneficial nutrients including tryptophan, folate, and magnesium. An essential mineral, magnesium is involved in muscle contraction and relaxation. Tryptophan and folate are involved in producing melatonin, the hormone that regulates our sleep cycles. These conclusions were drawn following an assessment of 969 U.S. adults who had what is considered a larger waistline -- 35 inches or more in women and 40 inches or more in men. The study was supported by the Avocado Nutrition Center, although the agency had no role in data collection, analysis, or interpretation. The researchers had initially intended to focus on heart health alone, before participants reported sleep-related benefits. "This was a cardiovascular health trial, making the sleep benefits more credible since they emerged as unexpected secondary findings in a well-designed randomized controlled trial," Dr. John Saito, a spokesperson for the American Academy of Sleep Medicine and pulmonologist at Children's Hospital of Orange County, told Verywell this week. Eating avocados daily was also associated with a better diet and lower cholesterol levels, the researchers reported, building on similar research from 2022. Studies have previously found that disrupted sleep is linked to high levels of cholesterol: the waxy, fat-like substance that can lead to heart attack and stroke. Improved heart health can help people to get better sleep, and getting enough sleep can also improve heart health and slash the risk of disease, according to the Centers for Disease Control and Prevention. Avocado's healthy fat and fiber contributed to positive cardiovascular impacts. The healthy fat can also help to reduce cholesterol levels, and lower the risk for potentially life-threatening cardiac events. The fiber is tied to a healthy gut and reduced risk of death from any cause. Adults should consume at least 25 grams of fiber each day, according to Harvard Medical School. Of course, healthy fat is still fat, and avocados are packed with both nutrients and calories. An entire large avocado can add upward of 400 calories to your daily diet, the Cleveland Clinic says. But, the fruits are still considered to be healthy when consumed in moderation like being added to a morning smoothie or a salad at lunch. Half an avocado has more potassium than a banana, the Harvard T.H. Chan School of Public Health said. Humans need potassium to help fend off high blood pressure, which can result in kidney disease, eye damage, coronary artery disease, and other complications, if it's left untreated. While the findings of the new study cannot be generalized to all populations, Petersen noted that heart health is influenced by many factors, such as fitness and genetics. 'This is an encouraging step in expanding the science around avocados and the potential benefits of consumption,' she said.

New Details Emerge About Ancient Inca Counting Technology
The Inca were a pre-Columbian civilization whose empire sprawled along South America's Pacific Coast from the 15th to the 16th century CE. Like other Andean peoples, they used khipus (also known as quipus), an intricate cord and knot system used to record information. According to Spanish colonial-era sources, only male Inca elites could make khipus. A new study, however, challenges this widespread notion. In a paper published today in Science Advances, an international team of researchers investigated the primary cord of a khipu from around 1498 CE made from human hair. Their analysis revealed that the individual who wove their hair into the khipu ate a diet commonly associated with commoners, suggesting that a greater diversity of people used the instrument than previously thought. 'Despite recent advances in our understanding of Andean khipus, scholars know little about the specialists who created Inka khipus,' the researchers wrote in the study. 'With limited direct evidence concerning the lives of Inka khipu experts, our knowledge is based mainly on the chronicles of Spanish-language colonial observers.' Researchers believe that khipus were buried alongside their owners when they died. Unfortunately, however, the burials where experts have discovered many Inca khipus were previously looted, meaning they can no longer provide this crucial insight. As such, the team from the new study took a different approach. 'Historically, when human hair was incorporated into a khipu's primary cord, it served as a 'signature' to indicate the person who created the khipu,' the researchers explained. 'Recent advances in elemental analysis–isotope ratio mass spectrometry allowed us to undertake simultaneous carbon (C), nitrogen (N), and sulfur (S) measurements from a single KH0631 hair sample, revealing that this individual consumed a diet characteristic of low-ranking commoners,' they added. 'This evidence suggests that Inka commoners could be involved in creating Inka-style khipus.' Specifically, the individual in question ate tubers and greens instead of meat and corn, which was the typical Inca elite's diet. The researchers' approach also revealed that this khipu specialist, or khipukamayuqs, probably lived in modern-day southern Peru or northern Chile. These results align with the fact that in the 19th and 20th centuries, 'commoners,' such as peasant farmers, farm laborers, and female peasants, created and used khipus. What's more, it bolsters recent research as well as accounts by Felipe Guamán Poma de Ayala, a 16th-century Inca nobleman and chronicler, that women in the Inca Empire also made khipus. While the researchers admit that 'KH0631 is only one khipu,' they conclude that 'the new isotopic evidence from KH0631 suggests that khipu literacy in the Inca Empire may have been more inclusive and widespread than hitherto thought.'

New study makes concerning discovery after testing samples from nearly 200 homes: 'It's a global problem'
New study makes concerning discovery after testing samples from nearly 200 homes: 'It's a global problem' Many people trust private wells to deliver clean, natural water — but a new study reveals that's not always the case. What's happening? A three-year study from Pennsylvania State University found that nearly one in five private wells tested in Pennsylvania contained PFAS — manmade "forever chemicals" linked to serious health problems. According to WESA, the researchers tested 167 private wells across the state and discovered that 18% showed PFAS contamination, with some exceeding federal safety limits. PFAS, or per- and polyfluoroalkyl substances, are a group of long-lasting chemicals often used in products like nonstick cookware, water-resistant clothing, and firefighting foam. They're known to build up in the human body and the environment, and they're now showing up in unexpected places — including people's homes. "It's a global problem that I think researchers as a whole should come together to figure out how to support communities who may be impacted vastly," said Faith Kibuye, a water resources extension specialist at Penn State, per WESA. Why is this finding concerning? Research has linked PFAS exposure to increased risk of cancer, weakened immune systems, hormone disruption, and developmental issues in children. With over 1 million households relying on private wells in Pennsylvania alone — many of which are located in rural or underserved areas — this issue has significant public health implications, WESA reported. Since state and federal water regulations don't cover private wells, homeowners must handle testing and treatment themselves. That makes PFAS contamination an invisible threat — one that families may not realize they're exposed to until it's too late. Unfortunately, this isn't an isolated case. One study revealed that nearly half of the U.S. tap water contains PFAS, and experts in the U.K. have called for tighter regulations on the presence of "forever chemicals" in their drinking water. These stories show just how widespread the problem is becoming. What's being done about PFAS in well water? The researchers hope their work will help spread awareness and prompt more homeowners to test their water. "It's also a good thing that we're getting a lot of awareness out there about PFAS in general and what people can do," Kibuye said, per WESA. In Pennsylvania, homeowners can turn to state-certified labs to test their well water for PFAS. If contamination shows up, filtration systems — like activated carbon or reverse osmosis — can help remove the chemicals. On a larger scale, several states have begun tightening regulations on PFAS use. Last year, the U.S. Environmental Protection Agency finalized nationwide limits for six types of PFAS in public water systems, and it confirmed this spring it intends to uphold those regulations under the new administration. Although current regulations exclude private wells, increasing awareness of the issue could help close that gap and give more families peace of mind about the water they rely on every day.
