A New Kind of Concrete Can Grow and Repair Itself. How? It's Alive.

Concrete is one of the biggest greenhouse gas emitters in the world, so scientists are developing new strategies to mitigate its climate impact. One of those strategies is to create a concrete that 'self-heals,' and in a new study, scientists used synthetic lichen to patch cracks autonomously (meaning that outside nutrients don't need to be applied for the repair to take place. The lichen—actually a combination of cyanobacteria and fungi—can draw food from sunlight and the atmosphere while also using calcium ions to produce calcium carbonate, which is the same ultra-strong material found in seashells and millennia-old Roman concrete. The production of concrete, as well as the key ingredient—cement—is one of the leading generators of CO2 emissions on Earth, contributing to at least 8 percent of the world's global budget. So, it's no surprise that scientists and engineers are trying to figure out ways to lower this building material's impact. One solution is to not use it altogether—the creation of mass timber buildings in the U.S. has been rapidly increasing in recent years. Another is to devise some way to make concrete more sustainable, or even find ways for it to be a carbon negative building material. However, the area that's gotten the most attention in the past few decades is figuring out how to make concrete longer-lasting, and even better than the widely used ultra-high performance concrete (UHPC). The most common method for increasing concrete's longevity is by ripping a page out of the Roman playbook and developing means for concrete to essentially 'self-heal.' The reason why the 2,000-year-old aqueducts throughout Italy don't look a day over 500 is because Romans used 'lime clasts' mixed in with concrete that essentially filled cracks before they formed. Now, scientists from Texas A&M University are investigating ways to pull off a similar trick using lichen. The results of the study were published in the journal Materials Today Communications. Of course, self-healing concrete isn't new—headlines have popped up for years touting new techniques for making concrete long lasting, and some have even used microbes. But the authors of this new study say they've stumbled upon a technique that improves on previous attempts in one major way. 'Microbe-mediated self-healing concrete has been extensively investigated for more than three decades' Congrui Grace Jin, senior author of the study from Texas A&M, said in a press statement, 'but it still suffers from one important limitation—none of the current self-healing approaches are fully autonomous since they require an external supply of nutrients for the healing agents to continuously produce repair materials.' Lichen, often found clinging to trees and rocks, is actually a complex symbiotic system filled with cyanobacteria, fungi, and algae. The researchers created a synthetic lichen that consisted of a cyanobacteria that can use sunlight (as well as elements from the atmosphere) as food, and some fungi that naturally produce materials that can seal cracks. Specifically, the fungi can pull in ionized calcium, which spurs the production of calcium carbonate—the ultra-hard material found in seashells and coral. (Calcium carbonate is actually the same material that made Rome's concrete extremely strong in antiquity.) In lab tests, the synthetic lichen was able to fill cracks—even in concrete—relying on just sunlight and air for food. Using this autonomous repair system can not only extend the life of concrete, but also cut down on repair costs. The authors are now testing whether this synthetic fungi could repair existing cracks as well. Challenges still remain for the widespread adoption of self-healing concrete. Right now, not many companies make the stuff, and it's still more expensive to produce that typical, run-of-the-mill concrete. Some experts say it could still be a decade before self-healing additives really take off. When that happens, though, the lichen will be ready.

'Very rare' military horse cemetery from Roman times unearthed in Germany

When you buy through links on our articles, Future and its syndication partners may earn a commission. Archaeologists in Germany have unearthed a vast horse cemetery from Roman times, a discovery that is "very rare," according to researchers. The excavation, conducted in Stuttgart's borough of Bad Cannstatt, has revealed the skeletal remains of more than 100 horses. These animals were part of a Roman cavalry unit known as Ala, which was active in what is now southwest Germany during the second century A.D., radiocarbon dating of the horses' bones revealed. "Finding such a large horse cemetery from Roman times is very rare," Sarah Roth, the archaeologist in charge at the State Office for Monument Preservation (LAD) in the Stuttgart Regional Council, told Live Science in an email. While a few horse burials had been found in Bad Cannstatt since the 1920s, a 2024 excavation ahead of a new construction project revealed that the burial ground was teeming with equid remains. "We hadn't expected to find so many horses still preserved in the ground," Roth said. "This was truly a surprise!" The warhorse cemetery also held the remains of a Roman-era man buried on his stomach and without grave goods, indicating that he likely was an outsider who wasn't held in high esteem. "Its [the body's] position suggests that the man was 'disposed of' here rather than given a regular burial," as a regular cemetery for people was only about 0.3 miles (0.5 kilometers) away, Roth said. Related: Roman-era skeletons buried in embrace, on top of a horse, weren't lovers, DNA analysis shows The Roman cavalry unit at Bad Cannstatt patrolled the border of the Roman Empire from about A.D. 100 to 150. "The horsemen were responsible for controlling their section of the border," Roth said. "As horses were the fastest means of transport on land at the time, they were in particular used in urgent emergencies." Ala likely included nearly 500 riders and at least 700 horses, according to a translated statement from LAD. When the unit's horses died, the Romans buried them in a specific area that was about 1,312 feet (400 meters) from the cavalry fort and 656 feet (200 m) from the civilian settlement. The dead horses were dragged into shallow pits and buried on their sides with their legs bent or straight. These burials likely had markers in Roman times, as they were packed closely together yet had very little overlap, Roth said in the statement. Image 1 of 2 In a rare burial, one of the horses was buried with grave goods next to its upper legs. Image 2 of 2 Archaeological work ahead of a new construction project by the Stuttgart Housing and Urban Development Company revealed the horse cemetery. Excavations of the cemetery started in July 2024. "The horses do not all appear to have died at the same time in a major event such as a battle or epidemic," Roth said in the statement. "Rather, the animals buried here either died of illness, injury, or other reasons during the Ala's presence in Bad Cannstatt." Alternatively, it's possible some "were no longer able to fulfill their role as military horses," she added. "If the horse could still walk on its own, it would have been brought to the horse cemetery and killed on site to avoid having to transport the heavy carcass."

Grave goods such as these are typically found in Roman-era burials for humans, making the jug and lamp "unusual" to find among horse bones, Roth told Live Science. "Of the approximately 100 horses we were able to examine, only one had received grave goods," she said. The horse cemetery offers a rare look at the use of horses in the Roman army. Further analyses will reveal the horses' sexes, ages at death and their sizes, as well as possible diseases they had and their causes of death. Future studies may also reveal their ancestral roots, where they were bred and if they were well kept and fed.

Blue-eyed 'Ice Prince' toddler was buried with a sword and a piglet 1,350 years ago in Bavaria

When you buy through links on our articles, Future and its syndication partners may earn a commission. A blue-eyed boy buried in southern Germany more than 1,300 years ago was interred with rare riches — including a small sword, silk clothes and a gold cross — indicating that he came from a wealthy local family before he died of an infection at about 18 months old, a new analysis finds. The remains of the child, dubbed the "Ice Prince" because archaeologists flash froze the burial chamber to excavate its contents in a single block, were discovered in 2021 near the town of Mattsies in Bavaria. The child's tomb was found south of the Upper Germanic Limes that once defined the Roman frontier. But the Western Roman Empire was extinguished in this area when Germanic tribes invaded in the early fifth century — centuries before the boy died in the seventh century. The latest research includes anatomical studies that estimated the boy was about 1.5 years old when he died, and radiocarbon dating that indicates he died between A.D. 670 and 680. A strontium isotope analysis of the enamel on his teeth indicated he was born in the region and had fed mainly on breast milk. Analysis of his DNA suggested the boy had blue eyes and light-colored hair. The studies also indicated that he had died from "chronic infection" caused by a middle-ear infection. The boy was buried in leather clothes and with a small sword on a richly decorated belt. Other details of the well-furnished grave and the rare remnants of a silk garment — a sign of wealth — indicated that the boy came from a locally important family, archaeologists for the German state of Bavaria said in a translated statement. Related: 1,800-year-old warhorse cemetery held remains of a beloved horse — and a man considered an 'outsider' to Roman society The toddler's stone burial chamber was discovered amid the remains of a Roman-age villa near Mattsies during excavations for new buildings, according to the translation of a 2021 statement. Archaeologists said the villa seemed to have been repurposed as a burial place for the child, perhaps in line with the concerns of his family. "The boy's death must have shocked his regionally important family," the statement said. "They apparently made great efforts to give the child a burial in keeping with his social status." The stone ceiling and walls of the burial chamber were tightly sealed against sediment, so the entire burial was in "excellent condition," the statement said. State government archaeologists decided to flash freeze the contents of the entire burial chamber using liquid nitrogen so it could be excavated as a single block over 14 hours. The researchers used liquid nitrogen because its temperature of minus 320 degrees Fahrenheit (minus 196 degrees Celsius) prevents freezing water from creating large and destructive ice crystals, the statement said. Image 1 of 3 The boy was about 18 months old when he died, but he was buried with a small sword and scabbard on a richly-decorated belt. Image 2 of 3 The latest studies have revealed new details of the sword, scabbard and belt buried with the young boy. Image 3 of 3 The "Ice Prince" was buried wearing silver bracelets and had silver spurs attached to his shoes. The latest studies reveal that the body was laid on a fur blanket within the chamber and that one of the boy's garments was a long-sleeved shirt made from linen and trimmed with strips of silk. At that time, silk was available only through the Byzantine Empire, and it was a rare status symbol. The fabrics' exceptional preservation due to the tightly sealed grave makes them an even more exceptional find, the researchers said. The boy was buried with silver bracelets on his arms and silver spurs attached to his shoes, according to the statement. Nowadays, most toddlers start walking at between 8 and 18 months of age, so it's possible this toddler had started walking before his death. The burial chamber also contained a cloth decorated with a cross made from thin strips of gold, which may indicate early Christian beliefs; Bavaria didn't become fully Christianized until after Charlemagne conquered it in the eighth century. In addition, several grave goods — including a bronze basin, a comb, a wooden bowl and a drinking cup with silver fittings — had been placed on a woven mat at the foot of the body.

What were once thought to be the bones of a dog have now been identified as the dismembered remains of a piglet, which may have been cooked and placed as a food offering. The investigations have also shown that the building where the Ice Prince was found was renovated twice in the years after the burial, which indicated that the site was used over a long period as a place of remembrance of the dead, the statement said.
