175-year-old theory about riverside ruins in Austria turns out to be true
On a riverside in eastern Austria sat a mysterious set of ruins. Some believed it to be an abandoned, run-down castle. Others thought it could be the remnants of a unique, ancient Roman structure.
When archaeologists finally excavated the ruins, they confirmed a 175-year-old theory.
Locals referred to the ruins near Stopfenreuth as 'Ödes Schloss,' a German nickname that roughly translates as 'Desolate Castle.' One archaeologist explored the still-visible ruins around 1850 and interpreted it as a Roman military fort, but later researchers who tried confirming this theory left the site still uncertain of its identity, the nearby Carnuntum Archaeological Park said in an article.
By the late 1800s, Ödes Schloss had become overgrown, buried and hidden from view. Yet the mystery of the odd, semi-circular structure lingered.
A joint team of archaeologists decided to revisit Ödes Schloss in 2024, the Austrian Academy of Sciences said in an April 14 news release. They took soil samples, excavated the site and started analyzing their finds.
The team soon realized Ödes Schloss wasn't a castle at all: It was a specific type of ancient Roman military base known as a bridgehead fort, the academy said. The 1850s archaeologists were right.
Roman bridgehead forts were typically built near key river crossings to control trade and secure borders, archaeologists said. As their name suggests, the forts often sat at the head of bridges but not always, such as in the case of Ödes Schloss.
Archaeologists identified the Roman bridgehead fort as a first-of-its-kind find for Austria.
Photos show the well-preserved ancient Roman ruins. In some sections, the walls still reach over 8 feet high, the academy said.
Park officials identified one section of the ruins as 'an internal corner tower and adjoining walls,' a 'particularly striking' find.
Archaeologists also found several bricks stamped with the names of Roman military units, coins, pottery and other metal artifacts. A photo shows some of these finds.
Based on the recent excavations, archaeologists identified two main phases in the fort's history, the academy said. The first phase began around 170 to 180 A.D. when the Romans built the fort as a reinforcement against Germanic tribes. The second phase took place around 260 A.D. when another Roman emperor renovated the fort.
Around the time of the fort's second phase, the nearby ancient Roman city of Carnuntum began to decline, park officials said. The fort's importance declined as well, and it was eventually abandoned.
Much about Ödes Schloss remains unknown. Archaeologists plan to continue analyzing the site and their finds.
Stopfenreuth is a small town in eastern Austria, a roughly 30-mile drive east of Vienna and near the border with Slovakia.

Labs reopen to study archaeological treasures
The laboratories used to carry out research on some of the country's most significant heritage sites have reopened after a refit. The Fort Cumberland Laboratories in Portsmouth have been equipped with tools to help understand how artefacts are made and how best to preserve them. The site has been central in projects ranging including the re-excavation of Silbury Hill in Wiltshire and studying human remains found at Hadrian's Wall. Historic England said the site "plays a vital role in telling the stories of England's past". Specialist work has been carried out at Fort Cumberland for the past 75 years. The team has helped conserve artefacts from the 18th Century Dutch warship the Rooswijk off the Kent coast and analysed human remains at Birdoswald Roman Fort Cemetery at Hadrian's Wall in Cumbria. The refit of the laboratories has involved new heating and cooling systems. New equipment includes a scanning electron microscope and energy dispersive spectrometry system (Sem-Eds) for analysing historic materials. It allows for imaging of very small features such as nanocrystals, as well as mapping the chemical composition of a wide range of materials. The system can be used to analyse dental wear in archaeological remains, the causes of bone discolouration, insect remains and historic building materials. Duncan Wilson, chief executive of Historic England, said: "The amazing work of our archaeologists and heritage scientists is helping to uncover the hidden stories that connect us to our distant past. "This new investment in Fort Cumberland's laboratories will enhance our research and conservation work, and improve access to our expertise, equipment and collections, helping more people to enjoy and care for their heritage."

Researchers make record-breaking discovery in quest for 'holy grail' of energy: 'A significant advance'
Solid-state batteries are a highly anticipated form of green tech for myriad reasons, and a team of German researchers just developed a novel material with incredible implications for this emerging technology. SSBs have been dubbed a "holy grail" of clean energy. They hold tremendous promise for cleaner, cheaper energy, and — as the name suggests — they employ solid materials rather than liquid electrolytes, as in lithium-ion batteries. Researchers at the Technical University of Munich recently published their SSB-related findings in the journal Advanced Energy Materials. According to Tech Xplore, what they discovered broke a "world record for ion conductivity." In a press release announcing the findings, TUM explained that a team of researchers working under professor Thomas Fässler "partially replaced lithium in a lithium antimonide compound with the metal scandium" and were stunned to discover that the novel material conducts ions "more than 30% faster than any previously known material." Partly replacing the lithium with scandium created gaps called "vacancies" in the material's lattice structure, which enabled ions to move and conduct energy far more efficiently. That's how researchers broke the previous record for lithium-ion conductivity in solid-state materials, which TUM said was a "critical metric for enabling faster charging and more efficient energy storage." Fässler remarked that his team's "result currently represents a significant advance in basic research" into solid-state batteries. SSBs are safer than their lithium-ion counterparts, charge much faster, are more eco-friendly, and can withstand far more charge/discharge cycles in their lifespan than batteries powered by liquid electrolytes. Moreover, their higher energy density means they can pack more power into less space, which is groundbreaking with respect to electric vehicle range. Their potential to extend EV ranges is perhaps the most prominent aspect of SSB development, but the technology has applications far beyond faster charging and longer drives. Solid-state batteries could be scaled up for industrial use — and, eventually, they might even power passenger planes. Fässler noted that "many tests are still needed before the material can be used" in SSBs, adding that researchers were "optimistic" about the impact of their discovery. He said the team had already filed a patent for their record-breaking discovery. Study co-author Jingwen Jiang focused on how their findings could inform bigger breakthroughs. "We believe that our discovery could have broader implications for enhancing conductivity in a wide range of other materials," he said. Should the U.S. invest more in battery innovations?

Merz hails BioNTech founders' 'courage' as they receive German prize
The co-founders of German drugmaker BioNTech, which was one of the first companies to develop an effective vaccine against the coronavirus, were honoured with Germany's National Prize on Tuesday. In his laudatory speech, Chancellor Friedrich Merz hailed Özlem Türeci and Ugur Sahin for their "extraordinary courage". "You both embody the future strength of a liberal society. As scientists who seek solutions. But also as entrepreneurs for whom responsibility is at the centre of their work," Merz said during the award ceremony held at Berlin's Französische Friedrichstadtkirche church. The two scientists, who specialize in the development of immunotherapies against cancer, infectious diseases and diseases of the immune and nervous system, developed a coronavirus vaccine in 2020, over the course of less than a year. Merz also praised the two researchers, who have Turkish roots, as examples of the importance of "skilled labour immigration as a driver of progress." "I want to live in a Germany in which talent is promoted to the best of our ability, regardless of social or ethnic background," said Merz. Ideologies calling this tenet into question jeopardize "the future of our liberal order with their narrow-mindedness," the German leader said. The German National Prize has been awarded by the German National Foundation since 1997 to individuals or organizations for their efforts to a democratic society. The award is endowed with a total of €50,000 ($57,000). The German National Foundation was established by former chancellor Helmut Schmidt and friends in 1993.
