Fossils Reveal Fierce Terrestrial Crocodiles Roamed Caribbean Islands Long after dinosaurs vanished from Earth, mammals rose to dominate. But they were not without rivals. In South America, ancient land-dwelling crocodiles known as sebecids emerged as apex predators. New fossil evidence suggests these powerful predators survived far longer than once believed—thanks to the Caribbean islands acting as a final refuge. A Predator from a Forgotten Age Scientists have discovered sebecid fossils in the Dominican Republic dating back 5 to 7 million years. This is significantly more recent than previously known sebecid remains, which were last recorded in Colombia around 10.5 to…

Shenzhou-19 Astronauts Transfer Space Experiment Samples for Scientific Study Samples from space experiments, brought back to Earth by the Shenzhou-19 mission, have now been handed over to scientists in Beijing. These materials are set to play a key role in advancing research in several scientific fields. Largest Batch of Biological Samples Returned by Shenzhou-19 The Shenzhou-19 spacecraft landed safely on Wednesday, returning from a six-month mission with a total of 37.25 kilograms of samples. The mission carried out 25 experiments in areas such as space life science, materials science, and emerging technologies. Out of these, 20 samples came from biological…
New Unit Reflects Rising Strategic Role of Space in New Zealand The New Zealand Air Force will establish a dedicated space squadron to support space-based defence and global security efforts, a senior official confirmed on Wednesday. The move highlights the increasing importance of space in national and international defence strategies. Air Vice-Marshal Darryn Webb, Chief of the Air Force, said that although the Air Force already has a team focused on space, formalising it into a squadron underscores its growing role. “Space is now part of our present and will only become more critical in the future,” Webb told Reuters.…
First Launch Marks Start of Project Kuiper Amazon has launched the first 27 satellites for its Project Kuiper, marking the beginning of a major broadband initiative. These satellites were sent into low-Earth orbit from Florida on Monday. The project aims to create a global internet network, challenging SpaceX’s established Starlink service. The satellites lifted off at 7 p.m. EDT from Cape Canaveral Space Force Station. They were carried by an Atlas V rocket, provided by United Launch Alliance (ULA), a joint venture between Boeing and Lockheed Martin. The launch followed a delay caused by bad weather earlier in April. Kuiper…
Global Military Spending Hits Record $2.72 Trillion in 2024 World military expenditure surged to $2.72 trillion in 2024, marking a 9.4% increase from 2023, according to a report from the Stockholm International Peace Research Institute (SIPRI). This rise is the sharpest year-on-year increase since the end of the Cold War. Rapid Growth Across All Regions SIPRI’s data showed that military spending rose in every world region due to heightened geopolitical tensions. Europe and the Middle East saw particularly rapid increases, reflecting growing concerns over regional security. “Over 100 countries around the world raised their military spending in 2024,” SIPRI reported.…
Fossil of Oldest-Known Ant Unearthed in Brazil Scientists have discovered the fossil of the oldest-known ant, a winged insect with fierce scythe-like jaws. It lived about 113 million years ago during the dinosaur era and was preserved in limestone found in northeastern Brazil. The species, named Vulcanidris cratensis, belonged to a group called hell ants, known for their menacing jaws. These ants thrived during the Cretaceous Period across a wide range but have no living descendants today. A previously found hell ant species, Haidomyrmex, was named after Hades, the Greek god of the underworld. A Fearsome Ancient Predator Vulcanidris cratensis…

Crackdown on Cyber-Scam Centres Faces Satellite Internet Challenge Joint Operation Frees Thousands in Myanmar In a rare joint effort in February, Thai and Myanmar authorities disrupted operations at cyber-scam centres by cutting electricity and internet access. This move freed around 7,000 trafficking victims from 29 different countries who had been forced to work in Myanmar. However, experts have questioned the long-term effectiveness of such actions. They warn that satellite internet technology, like Starlink, China’s SpaceSail, and Eutelsat from Europe, could soon make these blackouts obsolete. Satellite Internet Raises New Concerns Starlink, operated by Elon Musk’s SpaceX, offers portable, high-speed internet…
DeepSeek User Information Sent Abroad Without Consent South Korea’s data protection watchdog has taken issue with Chinese artificial intelligence company DeepSeek.

According to the Personal Information Protection Commission, the AI startup failed to gain proper approval from users before sharing their data. This information was reportedly sent to companies based in China and the US during the app’s launch phase in January. App Suspended Following Privacy Concerns In February, South Korea’s…
