Mighty Vikings battled severe diseases, reveals 10th-century skulls' study
The discovery of Viking Age skeletons in Varnhem, Sweden, provides valuable insight into people's lives from that era.
A year ago, researchers revealed the shocking state of their dental health.
A new study from the University of Gothenburg delves even deeper, examining entire skulls using cutting-edge X-ray techniques.
Swedish Vikings were plagued by serious health issues, including oral, facial, joint, and infectious diseases.
"The results of the study provide a greater understanding of these people's health and well-being. Everyone knows what it's like to have pain somewhere, you can get quite desperate for help," said Carolina Bertilsson, study lead, and an assistant researcher at the University of Gothenburg.
"But back then, they didn't have the medical and dental care we do, or the kind of pain relief—and antibiotics—we now have. If you developed an infection, it could stick around for a long time," Bertilsson added.
Researchers used computed tomography (CT scans) to peer inside 12th-century skulls from Varnhem, Sweden, a site known for its extensive and well-preserved skeletal remains.
The skulls studied belonged to nine male and six female Vikings, all of whom were adults aged between 20 to 60 years at the time of their death.
CT scans allowed researchers to examine skeletal damage in Viking skulls precisely and generated 3D images that provided layer-by-layer information about bone abnormalities.
These 3D images pointed toward an array of diseases, which were hidden for centuries.
It revealed pathological bone growths, signs of chronic sinus and ear infections, debilitating osteoarthritis, and rampant dental problems. These were not isolated cases — every skull examined told a story of pain and suffering.
'There was much to look at. We found many signs of disease in these individuals. Exactly why we don't know. While we can't study the damage in the soft tissue because it's no longer there, we can see the traces left in the skeletal structures," added Bertilsson.
The Vikings were highly skilled seafarers who traveled long distances using their distinctive longships. Moreover, they were both feared raiders and ambitious explorers, reaching far-flung locations like North America, the Mediterranean, and Eastern Europe.
The findings suggest chronic pain was a common and significant aspect of Viking existence.
Back in 2005, excavation near Varnhem Abbey uncovered over 300 skeletal remains from the 10th-12th centuries, which prompted this study. Earlier dental records were partially analyzed, but this research conducted a detailed examination of the well-preserved skulls.
This research on Viking skulls using CT scans is said to be a pilot study. A key goal of this pilot was to determine if CT scans could be a valuable tool for future, larger-scale studies of ancient skeletal remains.
"Very many of today's archaeological methods are invasive, with the need to remove bone or other tissue for analysis. This way, we can keep the remains completely intact yet still extract a great deal of information," noted Bertilsson in the press release.
The study also involved archaeologists from the Västergötlands Museum.
The findings were published in the journal BDJ Open.

Museum Centre Vapriikki: Ancient DNA Reveals 800-year-old Family Link in Medieval Finland
TAMPERE, Finland--(BUSINESS WIRE)--Ancient DNA research led by the Museum Centre Vapriikki in Tampere, Finland, in collaboration with the universities of Turku and Helsinki, has produced new insights into kinship, health, and population continuity in medieval and early modern Finland. Published in the peer-reviewed journal iScience, the research presents results from 25 individuals in Finland – a significant result in a country where acidic soils often lead to poor preservation of bones and genetic material. 'Although the dataset is relatively small, the findings clearly show that medieval Finland was not isolated,' Peltola notes. 'It was part of the wider networks of interaction that shaped northern Europe.' Share Researchers successfully recovered DNA from individuals buried between the 12th and 19th centuries at three cemeteries in the Tampere region. The study is part of Vapriikki's research project that applies scientific methods to investigate the region's past. Family ties and genetic continuity One of the study's findings was the discovery of full siblings buried 30 kilometers apart. A woman buried in Tampere and a man in Pälkäne, both from the 12th century, were confirmed to be sister and brother. 'This provides tangible evidence of family connections between different communities,' says Dr. Ulla Nordfors, researcher at Vapriikki. Comparisons with over 4,000 modern Finnish genomes from the Finnish Institute for Health and Welfare's biobank revealed that the ancient individuals from Tampere region share the closest genetic affinities with people living in the same region today. 'These results point to a remarkable degree of genetic continuity in the area since at least the early Middle Ages,' says Sanni Peltola, a doctoral researcher at the University of Helsinki. Additional genetic links were detected between Finnish individuals and previously published ancient genomes from Scandinavia and the Lake Ladoga region, providing evidence of mobility and cultural contacts in the Viking Age and beyond. 'Although the dataset is relatively small, the findings clearly show that medieval Finland was not isolated,' Peltola notes. 'It was part of the wider networks of interaction that shaped northern Europe.' Health and traits revealed The analysis also recovered microbial DNA that sheds light on health in past populations. Bacteria in 13th-century dental calculus included species linked to both oral and systemic health. DNA from a post-medieval man revealed the presence of Treponema, a bacterial genus that includes the causative agent of syphilis. Hereditary traits were also uncovered. Most individuals were lactose tolerant, like modern Finns, and a 12th-century man likely had corneal dystrophy, a degenerative eye disease that may have impaired his vision. 'Genes cannot capture the full complexity of a person and their life, but learning about health, traits, and family ties can help us see ancient people as individuals who once lived, felt, and experienced the world,' says Nordfors. 'When interpreted within their archaeological and historical context, these details allow us to approach the past on a more human level.'

Scientists make concerning discovering about hidden dangers lurking in recycling bins: 'This is the main obstacle'
Scientists make concerning discovering about hidden dangers lurking in recycling bins: 'This is the main obstacle' Recycling is a core defense against plastic pollution, but that does not mean it is a perfect solution. In fact, a team led by researchers from the University of Gothenburg found some real concerns lurking within recycled plastics. Addressing them is crucial to fulfill the potential of recycling, according to the school's press release. What's happening? To understand global plastic waste better, the scientists collected samples of recycled polyethylene plastic from various parts of the world. They let them soak in water for two days, and when they analyzed the water afterward, they found over 80 different chemicals leached from the plastic. Some were expected ingredients, but others were not supposed to be there, like pesticides, pharmaceuticals, and other toxic substances. These harmful compounds are often added to plastic but are not declared. Some may have also tainted the plastic during its life before it was recycled, the press release explained. Sounds nasty? Unfortunately, there's more. The aim of the new study was to explore the consequences of ingesting all of those chemicals on living organisms. The researchers put zebrafish larvae in the contaminated water for five days. That brief exposure was all it took to disrupt the organisms' hormones and metabolism, per the university. "This is the main obstacle with the idea of recycling plastic," Bethanie Carney Almroth, professor at the University of Gothenburg and project lead, said in a statement. "We never have full knowledge of what chemicals will end up in an item." Why is contaminated recycling important? The prevalence of plastic products in everyday human life was already a concern. Prior research shows that as they slowly break down, they wind up in the environment and our bodies, where they pose serious health risks. The research team's findings offer more evidence of why this plastic is so dangerous, even after it has been recycled. Much like the zebrafish in the study, exposure to the toxic chemicals they found also poses risks to humans' hormones, reproductive health, and metabolism, per the press release. "This work clearly demonstrates the need to address toxic chemicals in plastics materials and products, across their life cycle," Almroth affirmed in the statement. Do you worry about having toxic forever chemicals in your home? Majorly Sometimes Not really I don't know enough about them Click your choice to see results and speak your mind. What's being done to clean up plastic recycling? A global plastics treaty is in the works as a result of United Nations efforts. The presence of toxic chemicals in plastics and the lack of transparency in production lines are priorities in the negotiations. However, you do not need to wait for regulators and politicians to start minimizing your plastic use. Making easy switches from single-use products to reusable ones can save money and help you avoid some of the scary things that end up hiding in plastics.

‘Largest piece of Mars on Earth' catches massive $5.3 million bid at NY auction
The largest piece of Mars ever found on Earth was sold for just over $5 million at an auction of rare geological and archaeological objects in New York on Wednesday, while a juvenile dinosaur skeleton went for more than $30 million. The 54-pound (25-kilogram) rock named NWA 16788 was discovered in the Sahara Desert in Niger by a meteorite hunter in November 2023, after having been blown off the surface of Mars by a massive asteroid strike and traveling 140 million miles (225 million kilometers) to Earth, according to Sotheby's. The estimated sale price before the auction was $2 million to $4 million. The identity of the buyer was not immediately disclosed. The final bid was $4.3 million. Adding various fees and costs, the official bid price was about $5.3 million. Advertisement AP Two advance bids of $1.9 million and $2 million were submitted. The live bidding went slower than for many other objects that were sold, with the auctioneer trying to coax more offers and decreasing the $200,000 to $300,000 bid intervals to $100,000 after the proposals hit $4 million. The red, brown and gray meteorite is about 70% larger than the next largest piece of Mars found on Earth and represents nearly 7% of all the Martian material currently on this planet, Sotheby's says. It measures nearly 15 inches by 11 inches by 6 inches (375 millimeters by 279 millimeters by 152 millimeters). Advertisement It was also a rare find. There are only 400 Martian meteorites out of the more than 77,000 officially recognized meteorites found on Earth, the auction house says. AP 'This Martian meteorite is the largest piece of Mars we have ever found by a long shot,' Cassandra Hatton, vice chairman for science and natural history at Sotheby's, said in an interview before the auction. 'So it's more than double the size of what we previously thought was the largest piece of Mars.' It's not clear exactly when the meteorite was blasted off the surface of Mars, but testing showed it probably happened in recent years, Sotheby's says. Advertisement Hatton said a specialized lab examined a small piece of the red planet remnant and confirmed it was from Mars. It was compared with the distinct chemical composition of Martian meteorites discovered during the Viking space probe that landed on Mars in 1976, she said. The examination found that it is an 'olivine-microgabbroic shergottite,' a type of Martian rock formed from the slow cooling of Martian magma. It has a course-grained texture and contains the minerals pyroxene and olivine, Sotheby's says. Advertisement It also has a glassy surface, likely due to the high heat that burned it when it fell through Earth's atmosphere, Hatton said. 'So that was their first clue that this wasn't just some big rock on the ground,' she said. The meteorite previously was on exhibit at the Italian Space Agency in Rome. Sotheby's did not disclose the owner. Bidding for the juvenile Ceratosaurus nasicornis dinosaur skeleton started with a high advance bid of $6 million, then escalated with offers $500,000 higher than the last and later $1 million higher than the last before ending at $26 million. The official sale price was $30.5 million with fees and costs. The original estimate was $4 million to $6 million. Parts of the skeleton were found in 1996 near Laramie, Wyoming, at Bone Cabin Quarry, a gold mine for dinosaur bones. It's more than 6 feet (2 meters) tall and nearly 11 feet (3 meters) long. Specialists assembled nearly 140 fossil bones with some sculpted materials to recreate the skeleton and mounted it so it's ready to exhibit, Sotheby's says. The skeleton is believed to be from the late Jurassic period, about 150 million years ago, Sotheby's says. Ceratosaurus dinosaurs were bipeds with short arms that appear similar to the Tyrannosaurus rex, but smaller. Ceratosaurus dinosaurs could grow up to 25 feet (7.6 meters) long, while the Tyrannosaurs rex could be 40 feet (12 meters) long. Advertisement The skeleton was acquired last year by Fossilogic, a Utah-based fossil preparation and mounting company. Wednesday's auction was part of Sotheby's Geek Week 2025 and featured 122 items, including other meteorites, fossils and gem-quality minerals.
