Extraordinary discovery in Sardinia: dinosaur tracks found during filming of a documentary
The Italian island Sardinia is full of riches and breathtaking landscapes, but is also rich with history. A recent extraordinary scientific discovery is proof of this.
During the filming of a documentary on the region's geomorphological landscape, scientists found important palaeontological evidence in the countryside around Baunei, in Ogliastra: fossil traces testifying to the presence of dinosaurs in Sardinia.
The discovery was made by a scientific team composed of professors Antonio Assorgia, Sergio Ginesu and Stefania Sias, former lecturers at the Universities of Sassari and Cagliari.
Preserved in rocks dating back to the Jurassic period, the footprints belong to a theropod dinosaur never previously reported in Sardinia.
Thanks to the extraordinary discovery, it has been possible to reconstruct the animal's appearance and the environment in which it lived. The dinosaur was a biped from the Middle Jurassic period, around 165 million years ago, and lived along stretches of coastline with sandy and muddy sediments, typical of marshy and tidal areas. This was explained by experts at a press conference on Friday.
The rocky surface where the dinosaur's footprints were found also provided evidence of the presence of other coeval species. This is therefore the first evidence of the presence of dinosaurs in the Mesozoic period in Sardinia.
Stefania Salis, the first to notice those tracks, said the dinosaur discovered was named 'Bibi', and would be a female specimen, although we have to wait for scientific evidence to ascertain this.
"The footprints speak to us and tell us how things were 165 million years ago, the one from Baunei was probably a herbivore, given the lack of claws, and was a biped about 120 160 centimetres long," said palaeontologist and lecturer at the University of Sassari, Marco Zedda, speaking at the conference and explaining how from just a footprint, one can reconstruct the animal that left it.
According to Francesco Ginesu, Sole Director of the MGB company and responsible for the production of the documentary, this is an exceptional discovery, and emerged almost by chance. "As often happens in science, it has the power to radically change what we thought we knew," said Ginesu, adding that "those footprints, spotted while working on a popularised product, turned out to be a finding of enormous scientific value. It is not just one more piece of data: it is direct evidence of the presence of dinosaurs in an area that until now had not yielded such clear evidence."

The Dreadful Policies Halting Archeological Discoveries
Thanks to the creative application of new technologies, the 2020s are quietly shaping up to be a golden age of archaeology. In 2023, then-21-year-old Luke Farritor (now with the Department of Government Efficiency) combined machine‑learning pattern recognition with high‑resolution CT scans to decipher the first word from the Herculaneum scrolls—a Roman library charred by Mount Vesuvius in 79 A.D. Fully decrypting the library could ultimately double the surviving corpus of Ancient Greek and Roman literature—an unprecedented bonanza for classical scholarship. Analysis of ancient DNA has resolved long-debated questions about human migrations. After sequencing hundreds of Bronze Age human genomes, David Reich's research team at Harvard positively identified southwest Russia as the geographical origin of the Indo-European languages, while other genomic work has dated Homo sapiens-Neanderthal interbreeding to 47,000 years ago, several millennia prior to earlier best guesses. Fossilized human footprints in White Sands, New Mexico, have been conclusively dated to about 23,000 years ago—proof that people were in North America during the last Ice Age and forcing scholars to rethink when and how humans first crossed into the New World. Lidar has recently revealed massive ancient cities under jungle canopies, from the Mayan platform of Aguada Fénix in Mexico—larger than the Great Pyramid of Giza—to mysterious urban centers in the ancient Amazon. These developments—whether driven by artificial intelligence, the decryption of ancient genomics, or airborne lasers—promise to momentously expand society's understanding of humanity's past. Notably absent from this bounty, however, are the fruits of traditional, physical, Indiana Jones-style archaeology. The world of bits, as has often been the case these days, is leaving the world of atoms in the dust. While the storied bits over atoms problem is a complicated one, legal mechanisms are straightforwardly to blame for throttling archeological discovery. The case of Italian antiquities policy is paradigmatic. Since the 1930s, Italy—along with Greece, Turkey, and Egypt—has vested ownership of all antiquities in the state. Commerce in freshly unearthed artifacts is outlawed, and unauthorized excavation is punishable by hefty fines and sometimes prison time. Even using a metal detector requires a permit. Edward Luttwak, a historian and author of The Grand Strategy of the Roman Empire, explains that in Italy, "if you find something, you report it to the authorities. The authorities take it, goodbye. Most often, what they take from you, they put in a depot, a basement, a warehouse, and it never even gets shown." This is the unfortunate lot of the fortunate discoverer of an Italian artifact. Report a Roman coin? It'll be confiscated. Find an Etruscan urn while planting olives? Your land will be turned into an archaeological site the government may never have time to excavate. It's unsurprising, then, that Italians frequently don't report their findings to the government. Many artifacts end up on the black market (in 2023, Italy's Carabinieri Art Squad seized nearly 70,000 illegally excavated artifacts), or are even simply destroyed or hidden away. Private hoarding is an especially pernicious problem: When "illegally excavated" (read: most) Italian artifacts are privately held in people's houses, they are lost both to scholarship and public view. "You could fill twice the museums that exist in Italy from what people have hidden in their houses," says Luttwak, "which they wouldn't hide if you could report [them] to the authorities like they do in England." The British model provides a striking contrast. Since the 1996 Treasure Act, British law has required that significant archaeological finds be reported. Instead of simply seizing them, if the state wishes to retain an item, it must compensate the finder and landowner at its full market value. To capture the far larger universe of objects that fall outside the law's narrow legal definition of "treasure," the state-sponsored Portable Antiquities Scheme (PAS) established a voluntary nationwide program through which average Britons can log any find, whether or not the state intends to acquire it, into an open scientific database. As of 2020, over 1 million objects have been logged in PAS. According to Michael Lewis, head of Portable Antiquities and Treasure at the British Museum, over 90 percent of PAS-recorded items are found by metal detectorists on cultivated land, indicating how the scheme has turned what was once seen as a threat into a fountainhead of archaeological data. Thanks to these policies, Britain has been increasingly outpacing Italy in Roman archaeology despite its relatively modest classical history, as seen in this viral map of the provenance of hoards of Roman coins. Notice the sheer quantity of Roman coin discoveries reported in the U.K., far surpassing those in Italy. This disparity isn't explained by Roman Britain being richer than Roman Italy (quite the opposite), but by modern Britain recognizing and leveraging incentives to bring history out of occultation. The Great Stagnation of physical archaeology is a choice. The failure of policymakers to get the basics right—to make physical archaeology worth anyone's time—renders the richest landscapes fallow. Luttwak's attention is on one such landscape: the confluence of the Busento and Crati rivers on the edge of Cosenza, Calabria. Contemporary accounts record that in 410 A.D. the Visigoth chieftain Alaric—fresh from sacking Rome—was buried beneath the temporarily diverted river along with the treasures of the Eternal City. "Alaric's treasure is located in the southern part of the city of Cosenza," says Luttwak. "It was documented by an eyewitness." Alaric took "gold and silver objects…statues, and all kinds of things—possibly even the Temple menorah….When Alaric died in Cosenza, he got as the king one third of the treasure [to be] buried with him." "It could be found," explains Luttwak, "with hovering metal detectors, because he was buried with his weapons, too." Alaric's hoard—and maybe Judaism's most iconic physical symbol—should be discoverable today with an aerial anomaly survey and some clever hydraulics. The technology is ready; the incentives are not. Change the rules, and the payoff could be extraordinary. The post The Dreadful Policies Halting Archeological Discoveries appeared first on

Zion museum's new temporary exhibit delves into research on end-Triassic extinction
SPRINGDALE, Utah () — A new, temporary exhibit featuring research on the Triassic and Jurassic periods is available at the Zion Human History Museum. It features research on geoscience and extinction, as well as a model phytosaur skull. The new exhibit will bring guests through the late Triassic period, the end-Triassic Extinction, and the beginnings of the Jurassic period, between 227 to 180 million years ago. This is the culmination of a seven-year research project involving scientists from all over. Dr. Celina Suarez, a geoscience professor at the University of Arkansas, led the team. The rocks at Zion National Park were key to this research, as they were used to study and understand the climate change that led to the end-Triassic Extinction. Two Utah campgrounds included in list of 50 Favorite Places to Camp in America Right Now: Hipcamp According to a press release from Zion National Park, Dr. Suarez and her team identified 'a spike in CO2 levels in the park's Moenave Formation.' Using this information, the scientists were able to pinpoint a rapid increase in volcanic eruptions that led to the supercontinent Pangea splitting. 'We've got to look at the geologic past and all these past events to understand where we're going in the future,' Dr. Suarez is quoted in a press release. 'If we can just get one or two people that come and visit Zion to understand that … I've done my job.' Alongside that discovery, which is mirrored in sites all around the world, Dr. Suarez and the team of scientists found that the CO2 spike would also cause wildfires and 'intense weather patterns' that led to the End Triassic Extinction, which wiped out 'approximately 80 percent of all marine and terrestrial species on Earth,' according to the release. 10 hikes with stunning wildflowers across Utah The new exhibit at the Zion History Museum was built on this research, and was created by a collaboration between scientists, artists, and partners. Zion National Park extends a special thanks to the Zion Forever Project, St. George Dinosaur Discovery Museum, the Utah Geological Survey and the National Science Foundation in their release. 'None of us could have done anything to this scale by ourselves,' Robyn Henderek, the park's physical scientist, is quoted. 'We all had a role to play in this process.'

Are Pesticides in Your Food Harmful?
Credit - iStockphoto—Getty Images Various chemicals, from those in plastics to food additives, have made headlines lately for their potential roles in triggering diseases. Pesticides are unique among chemicals, though, says Melissa Perry, an environmental epidemiologist and dean of George Mason's College of Public Health. 'They're deliberately manufactured to kill things.' By poisoning weeds, pesticides clear the way for farmers' crops to thrive. But their deadly design may undermine human health, too. A recent report by a new federal advisory board, the Make America Healthy Again (MAHA) Commission chaired by Health Secretary Robert F. Kennedy Jr., calls for further investigation of pesticides' effects to determine if their use should be limited. Some evidence does suggest that long-term exposure could lead to cancer and several other serious health problems. More research is needed to better understand these risks, but in the meantime, experts recommend simple, practical steps to reduce intake. Here's what we know about the risks of pesticides and how to lower your exposure. The MAHA report assesses 'root causes' of poor health in U.S. children. It describes pesticides as one of eight types of chemicals giving rise to chronic diseases. The report specifically takes issue with two weed killers, glyphosate and atrazine. They're the most commonly used pesticides by American farmers, and research has focused on them in lab experiments on animals, with several concerning findings. Other studies have drawn links between glyphosate exposure—mainly by consuming trace amounts in food—and health problems, including earlier death. In 2019, a large research review identified a 'compelling link' between glyphosate intake and non-Hodgkin lymphoma in humans, though in 2024 a federal judge criticized this study's design and approach. Additional research points to a range of diseases potentially related to glyphosate, but a recent review by Italian researchers on glyphosate was inconclusive and called for further research. Read More: Seed Oils Don't Deserve Their Bad Reputation Based on the evidence, the World Health Organization (WHO) has described glyphosate as 'probably carcinogenic to humans,' whereas the U.S. Environmental Protection Agency (EPA) found 'no evidence that glyphosate causes cancer in humans,' citing a dataset the agency considered more thorough than WHO's. The second widespread pesticide highlighted by the MAHA report is atrazine. Like glyphosate, it's been used by farmers since the 1960s, but research on animals in the 1990s began to show it could disrupt reproductive health and hormone regulation. Tyrone B. Hayes, a biologist at the University of California, Berkeley, found that atrazine interfered with the sexual development of frogs. Subsequent studies showed similar effects, as well as weight gain, in mice. Researchers have also observed that women in certain agricultural communities experience higher rates of abnormal menstrual cycles, compared to places with fewer farms. Other human studies show increases in several kinds of birth defects. Still more research links atrazine to breast cancer, but researchers at the National Institutes of Health have concluded 'no evidence of an association' with cancer. The EPA estimated that atrazine adversely affects 54% of all species and 50% of all critical habitats. 'I don't know how an Environmental Protection Agency can make a statement like that and then re-register the chemical,' Hayes says. In 2023, U.S. Department of Agriculture (USDA) data showed that 99% of food samples tested below the EPA's safety limit for pesticides. However, U.S. limits are considerably higher than what's allowed in the European Union, where atrazine has been effectively banned. Read More: The Best Longevity Habit You're Not Thinking About Pesticides called organophosphates have been studied by the EPA and others for links to neurological disorders such as ADHD. 'Research clearly shows that children exposed to higher levels did have more neurobehavioral problems,' says Jason Richardson, professor of physiology and pharmacology at the University of Georgia's Isakson Center for Neurological Disease Research. Overall, uncertainty and debate about pesticides continues partly due to research challenges. People are typically exposed to multiple types of chemicals, so it's 'hard to attribute disease to one pesticide or pinpoint the definitive dose or exposure time' that makes people sick, Perry says. 'Just because a chemical is present doesn't mean it's doing anything bad, but in combination with other chemicals, it may be,' Richardson says. 'Efforts are underway to measure these combinations.' 'The country's agricultural policy follows science, not fear, speculation, and fringe narratives,' says Becky Langer-Curry, director of innovation at the National Corn Growers Association. The Corn Growers were 'perplexed' by the MAHA report, she adds. 'We need faith in the EPA's regulatory system to review the science. They're ensuring our food is safe, well below human risk.' In an email to EPA spokesperson Mike Bastasch said the EPA'typically regulates pesticides at least 100 times lower than where no adverse effects are seen in safety studies.' The agency is 'confident that the fruits and vegetables our children are eating are safer than ever,' Bastasch wrote. However, he added that the EPA is updating its evaluation of glyphosate's cancer-causing potential, and it's currently working on an Updated Mitigation Proposal for atrazine. In the meantime, researchers including Perry, Richardson, and Hayes think pesticides are dangerous enough that people should take precautions—but especially young kids, people who are pregnant, those who live close to farms, agricultural workers, and seniors. The first step is to become aware of pesticides in your environment. They're more common than people think, Perry says. 'Exposures happen routinely for most members of the American public.' Experts recommend contacting the environmental office of your county or city to learn whether you're close to a food production facility that uses pesticides. In 2017, kids and teachers at a Hawaii middle school reported unusual throat irritation and dizziness. They suspected the symptoms were caused by pesticides applied in nearby fields, and researchers found residues in the school's indoor and outdoor air samples. Read More: What to Do If Fluoride Is Removed From Your Water The detected levels were deemed below concerning thresholds. Bastasch says that, for communities near farms, the EPA studies potential exposure through the air and other pathways to make sure safety levels are based on sound science. Still, Hayes worries about the long-term effects of pesticide contact and absorption. 'For someone living in a farming community that's constantly exposed to estrogen mimics like atrazine, you're more likely to develop adverse effects,' he says. People take in atrazine mainly through their drinking water, after farm runoff carries the pesticide into local water systems. But some utilities are more effective than others at removing pesticide residues. The Environmental Working Group rates local water utilities. For people on well water, the federal government provides guidelines for testing it. Pesticide use is widespread enough—and disperses at such distances—that everyone should probably use a high-quality water filter, experts say. Atrazine can travel as far as 600 miles, Hayes says. As far back as 1999, USGS noticed that pesticides, including atrazine, were detected in places where farmers hadn't applied them. Even for residents of areas where a water treatment plant removes the chemicals, buying a filter certified to the NSF/ANSI Standards 42 and 53 provides some additional assurance of water safety. Look for filters in refrigerators and water pitchers that meet this certification. Eating organic foods can also help to reduce intake of pesticides, especially glyphosate. About 90% of pregnant women have detectable amounts of glyphosate in their bodies, according to one study. 'But when you put people on organic diets, you start to see that they no longer have pesticides in their urine,' Perry says. Research in 2020 found that eating an organic diet dropped glyphosate levels by 70% in children and their parents. In 2023, researchers put pregnant women on an organic diet for one week. Those who went all-organic decreased glyphosate in their urine by 43%. A 2019 study found a 95% reduction in organophosphates. Richardson calls these studies on organic foods 'intriguing' while noting that natural compounds used in organic farming may also be toxic beyond certain thresholds. Even when eating organic, 'make sure you wash your fruits and vegetables very well,' he says. Read More: Dermatologists Have a Dirty Little Secret One study found that soaking apples in baking soda mixed with water for 12-15 minutes eliminated more residue than water alone. However, according to another study, washing produce with running water is superior to baking soda, sitting water, and vinegar. Other research shows a gentle rubbing action during washing is effective. Aim for 20-30 seconds or longer if you have time. Peeling the skin and outer pulp will get rid of additional residue that penetrates into some produce. There's a major downside, though: you lose a portion of the beneficial nutrients and compounds, like fiber and vitamins, that help protect against pesticide toxicity. Some research suggests that replacing processed foods with diverse whole foods can reduce how many pesticides you ingest (but some research suggests there may be fewer benefits if they're not organic). Aside from nutrition, other lifestyle behaviors such as exercise, stress management, and good sleep may build a baseline of health that helps thwart the cumulative effects of pesticides and other pollutants. Overall, they influence how someone's body responds to their 'exposome,' Richardson explains—your total environmental exposures and how they interact with lifestyle behaviors and risk factors like age and genetics. Bastasch says the EPA assesses the combined risks of groups of pesticides that affect the body in similar ways, adding that the agency is continuing to advance research in this area. The exposome probably matters more than any one chemical type, but 'we're really just breaking the surface of understanding these interactions,' Richardson says. Until more definitive science emerges, maintain smart practices like scrubbing produce and striving for a healthy lifestyle. Contact us at letters@
