Dinosaur tail found in Chile stuns scientists
AFP
Chilean paleontologists on Wednesday presented their findings on a dinosaur discovered three years ago in Patagonia which they said had a highly unusual tail that has stumped researchers
The remains of the Stegouros elengassen were discovered during excavations in 2018 at Cerro Guido, a site known to harbor numerous fossils, by a team who believed they were dealing with an already known species of dinosaur until they examined its tail.
“That was the main surprise,” said Alexander Vargas, one of the paleontologists. “This structure is absolutely amazing.”
“The tail was covered with seven pairs of osteoderms … producing a weapon absolutely different from anything we know in any dinosaur,” added the researcher during a presentation of the discovery at the University of Chile.
The osteoderms — structures of bony plaques located in the dermal layers of the skin – were aligned on either side of the tail, making it resemble a large fern.
Paleontologists have discovered 80 percent of the dinosaur’s skeleton and estimate that the animal lived in the area 71 to 74.9 million years ago. It was about two meters (almost seven feet) long, weighed 150 kilograms (330 pounds) and was a herbivore.
According to the scientists, who published their research in the journal Nature, the animal could represent a hitherto unknown lineage of armored dinosaur never seen in the southern hemisphere but already identified in the northern part of the continent.
“We don’t know why (the tail) evolved. We do know that within armored dinosaur groups there seems to be a tendency to independently develop different osteoderm-based defense mechanisms,” said Sergio Soto, another member of the team.
The Cerro Guido area, in the Las Chinas valley 3,000 km (1,800 miles) south of Santiago, stretches for 15 kilometers. Various rock outcrops contain numerous fossils.
The finds there allowed the scientists to surmise that present-day America and Antarctica were close to each other millions of years ago.
“There is strong evidence that there is a biogeographic link with other parts of the planet, in this case Antarctica and Australia, because we have two armored dinosaurs there closely related” to the Stegouros, said Soto.

French Parliament Moves to Approve Social Media Age Limit for Minors
France’s Parliament is expected to approve legislation on Tuesday banning children under the age of 15 from accessing social media platforms, following an agreement reached Monday between lawmakers on the mechanism to enforce the measure.
The initiative is part of President Emmanuel Macron’s broader effort to strengthen online protections for minors and regulate children’s screen time before the end of his second presidential term in May 2027.
“Tomorrow, France will become the first country in Europe to establish a digital age of majority to better protect our children online,” Digital Affairs Minister Anne Le Hénanff said Monday in a post on X.
If approved, the government plans to implement the restriction in September, when students return to school after the summer holidays.
The United Kingdom has already passed similar legislation restricting social media access for users under the age of 16, although that measure is scheduled to take effect in early 2027.
Both the National Assembly, France’s lower house of Parliament, and the Senate are expected to hold final votes on the legislation Tuesday after a joint committee of seven senators and seven lawmakers reached an agreement on the bill’s final wording.
Under the proposed law, children under 15 years old would be prohibited from accessing online social media services, with limited exceptions for certain platforms, including online encyclopedias.
The legislation would make France the first member of the European Union to introduce a nationwide minimum digital age for access to social media platforms, reflecting a growing international movement to strengthen online safeguards for children and teenagers.

WHO to Hold New Round of Talks After Slow Progress on Pandemic Accord
Member states of the World Health Organization (WHO) made limited progress during the seventh session of the Intergovernmental Working Group (IGWG) tasked with finalizing a key annex to the global pandemic agreement, prompting negotiators to schedule another round of talks in September.
The session, which opened on July 6 and concluded last week at WHO headquarters in Geneva, focused on drafting and negotiating the annex covering the Pathogen Access and Benefit-Sharing (PABS) System, a central component of the pandemic accord.
Without the completion of the PABS annex, the global pandemic agreement cannot enter into force.
The annex had originally been expected to be finalized before May 2026, but negotiations have progressed more slowly than anticipated.
In a statement, the WHO said member states “advanced negotiations” on the PABS system while acknowledging that additional discussions are required to complete a framework capable of supporting a faster, more effective and more equitable response to future pandemics.
The organization announced that an eighth round of negotiations will take place on September 14.
Despite the limited progress, delegates succeeded in streamlining the draft text and concentrating discussions on several technical issues.
According to the WHO, negotiators focused on the contractual arrangements underpinning the PABS mechanism, the laboratory networks responsible for handling and sharing pathogens and their genetic sequence data, as well as the framework for distributing the benefits generated through the sharing of those pathogens.
The PABS system is considered one of the most important elements of the future pandemic agreement, as it aims to ensure timely access to pathogens for scientific research while establishing fair mechanisms for sharing the benefits derived from vaccines, diagnostics and other medical countermeasures developed during future global health emergencies.

Iran Says It Is in “Full-Scale War” as U.S. Launches Ninth Consecutive Night of Airstrikes
Iran declared on Monday that it is facing a “full-scale war” against the United States after Washington carried out another wave of overnight airstrikes, including attacks near a city that hosts one of the country’s nuclear facilities.
Iranian President Masoud Pezeshkian said the country must prepare for the consequences of the ongoing conflict, describing the situation as a broad military confrontation.
“The reality is that today the Islamic Republic of Iran is engaged in a full-scale war,” Pezeshkian said in a statement released by the presidency. “We must be realistic and accept the natural consequences of this resistance.”
The latest U.S. strikes marked the ninth consecutive night of military operations, according to the U.S. Central Command (CENTCOM), which announced the attacks on X.
Since hostilities resumed on July 7, U.S. air operations have expanded well beyond southern Iran, reaching central and northwestern regions of the country, according to local sources.
Local authorities reported that one person was killed and several others injured in Tabriz, in northwestern Iran, more than 1,000 kilometers from the Persian Gulf.
Additional casualties were reported in the nearby city of Urmia, where several people were wounded during separate strikes.
Washington said the attacks targeted military installations. However, Iranian officials accused the United States of striking populated areas, including Bushehr, home to Iran’s only operational nuclear power plant.
Iran also reported that the Darkhovin nuclear facility, which is still under construction, was among the sites hit during the latest attacks.
U.S. President Donald Trump said on Sunday that the renewed military campaign was carried out in honor of American service members killed in recent days.
Two U.S. soldiers died on Friday during attacks on a military base in Jordan, while another service member was killed on Sunday during the controlled disposal of unexploded munitions from an Iranian drone in northern Iraq.
According to U.S. figures, 17 American troops have been killed since the conflict began on February 28.
On the Iranian side, the latest official figures released on Friday reported 50 deaths and more than 500 injuries since fighting resumed earlier this month.
A memorandum of understanding signed by Iran and the United States on June 17, which had been intended to pave the way for peace negotiations, collapsed after hostilities resumed over the strategic control of the Strait of Hormuz, one of the world’s most important energy shipping routes.
