Volunteer divers have recorded what researchers believe is the first footage of a great white shark filmed underwater in the Mediterranean, captured during a ghost net removal dive near a shipwreck in the Strait of Sicily.

Derk Remmers, a technical diver with Ghost Diving, was about 40 meters (131 feet) below the surface between Sicily and Tunisia when the shark appeared. He filmed the encounter. The footage and photographs were released on June 8 to mark World Oceans Day.

Remmers said that the odds of meeting such an animal underwater are far lower than winning the lottery, and that his hands were shaking as he filmed.

The shark circled the group, then turned and moved back toward the divers. Remmers said that its behavior appeared calm and curious, not aggressive. When the team released air from their regulators, the shark picked up speed and disappeared from view.

First great white shark sighting in the Mediterranean stuns researchers

Marine biologists who reviewed the footage called the sighting rare and scientifically significant.

Dr. Carlo Cattano, a researcher at the Sicily Marine Centre of the Stazione Zoologica Anton Dohrn, said that most knowledge of great white sharks in the region has come from dead animals caught accidentally in fishing nets, and that direct observations help researchers better understand the species.

He said that prior research had already identified the area as a key location for threatened species and that this sighting reinforces its conservation value. Researchers cautioned that broader conclusions would require further study.

The mission was organized by the Healthy Seas Foundation, along with Ghost Diving and the Society for the Documentation of Submerged Sites. The wreck’s location is being kept confidential.

Ghost nets, fishing gear lost or abandoned at sea, continue killing marine life long after leaving a vessel. Previous dives at the site documented loggerhead sea turtles and large fish species caught in the gear.

Shipwrecks attract marine life, and when ghost nets settle on them, those structures become underwater traps.

Ghost nets turn shipwreck ecosystems into ongoing ocean traps

Veronika Mikos, director of Healthy Seas, said that the sighting is a reminder of how much marine life still exists in offshore Mediterranean waters and how much is at risk from discarded gear and overfishing.

Remmers said that between 1% and 10% of all fishing gear worldwide is lost each year, possibly adding more than 500,000 metric tons of abandoned nets to the ocean annually.

He said that the shark’s presence near the wreck signals an abundance of prey, and that those same animals face entanglement risk. Volunteer cleanups alone cannot resolve the problem, he said, and stronger action against industrial and illegal fishing is needed.

The mission also included environmental DNA sampling and underwater monitoring. Healthy Seas said that it plans to release additional footage and scientific material in the coming weeks.

A federal judge ruled on Monday that the $100,000 fee Trump imposed on H-1B visa applications was unlawful, striking down one of the administration’s key immigration measures targeting skilled foreign workers.

U.S. District Judge Leo Sorokin of Boston found the payment was a tax, not a penalty, and that the president lacked authority to impose it without congressional approval. His 42-page ruling also barred the State Department and U.S. Citizenship and Immigration Services from enforcing the requirement.

Sorokin, appointed by former President Barack Obama, applied reasoning from a February Supreme Court decision that struck down Trump’s tariffs issued under emergency authority. He concluded that immigration law, like the emergency statute in that case, does not permit the president to levy taxes.

Inside Trump’s case for the $100,000 H-1B visa fee

The H-1B program allows U.S. companies to hire foreign workers for specialized roles. Applicants must hold at least a bachelor’s degree. Visas are approved for three years with a possible three-year extension.

Each year, the program makes 65,000 visa slots available, along with a separate pool of 20,000 set aside for applicants holding advanced degrees.

Employers typically paid $2,000 to $5,000 in fees before the order. Economists say the program helps American companies stay competitive and creates domestic jobs.

Trump announced the $100,000 H-1B visa requirement in September, saying the program had been misused to replace American workers with cheaper foreign labor.

The fee did not apply to foreign nationals already in the country on student visas, who represent a significant portion of new applicants.

The requirement saw little uptake. USCIS recorded only 85 payments as of Feb. 15, according to a March court filing.

Attorneys General celebrate as administration vows to appeal

Twenty Democratic attorneys general filed the lawsuit in December. California Attorney General Rob Bonta, who led the group, said that the ruling protects the country’s ability to attract skilled workers, on which the economy depends.

New York Attorney General Letitia James said that it blocked what she called an unlawful effort to undermine the program and the jobs it supports.

The administration defended the policy as a lawful use of presidential authority over immigration. White House spokeswoman Taylor Rogers said that the ruling would be appealed, adding that the president has the authority to restrict the entry of foreign nationals deemed harmful to American interests.

Justice Department spokeswoman Natalie Baldassarre said that the department would continue holding companies accountable for misusing the program.

At least three lawsuits have targeted the fee. A federal judge in Washington ruled in December in favor of the administration in a separate case brought by the U.S. Chamber of Commerce, which is appealing that outcome.

The administration has also called for stricter applicant screening and put forward a revised selection process designed to give priority to foreign workers with higher qualifications and better pay.

Researchers have confirmed that an underwater helmet hoard off Spain’s eastern coast near Benicarló is medieval rather than Ancient Roman as long assumed. The finding places the collection in the late 14th to early 15th century, during a period of intense maritime conflict along the Valencian coast.

The study was led by Manuel Frallicciardi, a doctoral student jointly supervised by the University of Alicante and the University of Salerno, and published in the journal Antiquity. It marks the first time radiocarbon dating has been applied to iron helmets from an underwater site.

Divers recovered the helmets in 1990 from Piedras de la Barbada, a submerged site about six meters (20 feet) deep near Benicarló in eastern Spain. At least forty-three helmets were identified. Split between two institutions, most of the helmets are stored at the Museu de Belles Arts de Castelló, while two conserved ones are on display at the Museo de la Ciudad de Benicarló.

Because the site had also yielded Roman-era artifacts, including ancient amphorae and Punic War-era bronze helmets, early researchers assumed the iron helmets belonged to the same ancient period.

Fabric linings within helmets unlocked dating mystery

Frallicciardi and his team found organic evidence trapped inside the helmets. Marine sediment had sealed fabric linings in place, protecting them from full decay. The fibers, identified as plant-based bast material in a plain tabby weave, were sent to the Beta Analytic laboratory in Miami and the Curt-Engelhorn-Zentrum Archaeometrie in Mannheim, Germany.

Four of the five radiocarbon results clustered between the last quarter of the 14th century and the early 15th century. One sample returned a date roughly 150 years later than the rest. Researchers linked this to post-depositional contamination. That helmet sat in a more exposed position, and microscopic analysis showed its fibers were more degraded, conditions that could allow younger carbon to infiltrate the sample.

Spain’s underwater helmet hoard links to medieval piracy era

The helmets fall into two types. Most have rounded skull caps with a central ridge, resembling simplified infantry helmets documented in medieval sources, including the Holkham Bible from around 1330 to 1340 and a fresco painted by Jacopo Uccello around 1378. One helmet has a six-panel faceted construction comparable to a kettle hat depicted in a 1437 altarpiece by Hans Multscher.

Frallicciardi noted the helmets predate the era when large Italian and German workshops standardized European armor production. Their simple construction points to smaller regional workshops supplying local infantry markets. The historical context strengthens that picture. From the 1370s onward, Islamic piracy along the Valencian coast intensified sharply, peaking in the final decades of the 14th century.

Communities responded by building coastal towers, fortifying settlements, and mobilizing local militias. Researchers believe the helmets were most likely lost at sea during this period of sustained maritime insecurity.

Archaeologists have uncovered the remains of a Roman basilica at Tusculum, an ancient city located about 30 kilometers (18.6 miles) from Rome, dating it back to the 2nd century B.C.

The discovery places the structure among the oldest known examples of Roman public basilica architecture, adding a significant piece to the puzzle of how Rome shaped its cities during the Republican era.

Researchers from the Spanish School of History and Archaeology in Rome, known as EEHAR-CSIC, made the find in the southern part of Tusculum’s forum. The forum served as the political and social heart of the city.

The basilica had remained hidden beneath later imperial-era structures for centuries. Antonio Pizzo, who leads the project, said the building is one of the earliest known examples of its type and joins a small, well-documented group of Republican basilicas.

Inside Tusculum’s ancient Roman basilica and its rare design

The structure measured 17.7 by 25.2 meters (58 by 82.7 feet). Its monumental facade featured a series of arches resting on nine flat pilasters, an architectural arrangement known as the “Theatermotiv.”

Pizzo noted that if researchers confirm this interpretation, it would mark the first time this design appears in Roman architecture. Until now, this style had only been identified in later, exceptional buildings such as the Tabularium in Rome.

Among the most striking finds was a polychrome stucco capital discovered inside one of the building’s rooms. It depicts a female head rising from a cup of acanthus leaves, flanked by Ionic scrolls and floral motifs painted in white, red, and green.

The timing of the basilica’s construction aligns with the rise of powerful families from Tusculum, including the Mamilia, Fulvia, and Porcia clans.

The Porcia family produced Marcus Porcius Cato, famous for his repeated calls to destroy Carthage before the Third Punic War. Pizzo said these families drove a wave of monumental construction that went hand in hand with Rome’s growing power across the Mediterranean.

Powerful families and a Roman general add historical depth

Researchers also linked the site to Marcus Fulvius Nobilior, one of the most influential figures of the 2nd century B.C.

After defeating the Aetolian League in Greece, he returned to Rome with Hellenistic art and treasures. An inscription found at Tusculum confirms that some of that spoil went to his hometown.

Francesco De Stefano, co-author of the study published in the Journal of Roman Archaeology, said the discovery contributes valuable knowledge about the origins of this building type and key innovations in Roman public architecture.

The EEHAR-CSIC team has worked at Tusculum continuously since 1994, excavating its forum, theater, and baths. In 2023, they also uncovered a well-preserved marble female statue, with further details expected soon.

The ancient Greek Acropolises meant very different things to different people across history. A new study finds its symbolic meaning shifted dramatically over centuries, starting as a marker of civic pride and freedom before becoming firmly associated with tyranny and oppression.

Robin Rönnlund, an archaeologist at the University of Gothenburg in Sweden, published the study in the Annual of the British School at Athens. He examined ancient texts from Homer through the second century A.D. and traced how writers, philosophers, and inscription makers actually understood the word “acropolis” across roughly 1,000 years.

The research directly challenges a widely accepted scholarly narrative. For decades, historians described acropolises as prehistoric royal strongholds that were later abandoned and converted into either religious sanctuaries or civilian refuges during attacks.

Scholars built a false narrative around misread Aristotle

Rönnlund traces this narrative back to a misreading of a passage in Aristotle’s Politics, in which Aristotle theorized that acropolises suited oligarchies and monarchies.

Past scholars interpreted this theoretical statement as a historical sequence rather than a practical observation about fortifications, and the misreading quietly shaped academic thinking for generations.

The word itself is also commonly misunderstood. Rönnlund explains “acropolis” does not mean “upper city,” as dictionaries suggest. It more precisely means “the farthest polis” or “the polis on the edge,” and it first appeared in the Odyssey in reference to Troy.

In early Greek poetry, the ancient Greek acropolis carried an unmistakably positive meaning. Simonides described the Acropolis as a symbol of Greek resistance to Persian invaders.

Ancient Greek Acropolis once stood for freedom and pride

Sparta was celebrated as the “acropolis of Greece” in the famous Lysander monument at Delphi. Philosophers extended the metaphor further. Plato called the head the “acropolis of the soul.”

Diocles of Karystos described the mind as a sacred statue placed on the acropolis of the body. These uses reflected strength, protection, and honor.

The meaning turned darker as foreign military occupation became widespread. Ancient sources contain 66 passages linking tyrants to acropolises. Plutarch recorded a warning that Caesar should not be established as “tyrant in the acropolis.”

Macedonian forces turned a civic symbol into oppression

After 322 B.C., Macedonian forces systematically garrisoned acropolises across Greece to keep conquered cities under control. Both Demosthenes and Isocrates described how garrisoned acropolises kept entire regions in submission.

Civilian populations almost never used acropolises as refuges, contrary to popular assumption. The sites lacked sufficient water and supplies for prolonged occupation, and literary sources confirm people typically fled to the walled city below or into the countryside during attacks.

Rönnlund reviewed 133 individual acropolises mentioned in ancient sources and calls for future research combining archaeology, epigraphy, and field surveys to properly reconstruct how these sites functioned in ancient Greek life.
