Cauliflower Coral Crown: A Mind-Bending Win for Close-Up Photographer of the Year

Australian photographer Ross Gudgeon won the grand prize at the Close-Up Photographer of the Year with an extreme close-up of a cauliflower-soft coral in Indonesia’s Lembeh Strait, captured using an underwater probe lens; the 7th edition drew over 12,000 entries from 63 countries across multiple macro and micro categories, highlighting tiny wonders from mayflies and stingless bees to moths and frogs in vivid, intimate detail.

Zealandia Declared: Earth's Hidden Eighth Continent Unveiled Beneath the Pacific

Scientists have formally recognized Zealandia as Earth's eighth continent—spanning about five million square kilometers with more than 94% submerged in the Pacific—after International Ocean Discovery Program drilling and peer‑reviewed studies showing it meets continental criteria (thicker crust, coherent landmass, and ancient terrestrial fossils). This confirmation reshapes our understanding of Earth’s crust and could influence future maritime claims and exploration.

Car Trade-Ins Leave Buyers Underwater, Owing Thousands

Edmunds data for Q4 2025 show 29.3% of trade-ins were underwater — nearly a record high — with the average underwater balance at $7,214 and more than a quarter carrying over $10,000 in negative equity. Those rolling it into new loans faced an average monthly payment of $916, with about 40.7% choosing 84‑month terms. The trend traces to pandemic-era pricing and limited leasing options; relief may come from MSRP-friendly deals, but many cars will remain underwater until depreciation slows enough for the balance to fall below value.

"Millie Bobby Brown's Unforgettable Engagement Proposal Mishap"

Millie Bobby Brown revealed the story of her underwater engagement to Jake Bongiovi, detailing how he proposed with a ring inside a shell while diving, leading to a moment of confusion and the ring nearly getting lost in the ocean. Despite the mishaps, Brown sees it as a reflection of their ability to support each other in their relationship.

"Uncovering the Mystery of Underwater Sleep in Marine Mammals"

Marine mammals have adapted various sleeping strategies to rest underwater, including unihemispheric sleep, where one half of the brain sleeps while the other remains alert. Dolphins and some bird species utilize this technique to maintain awareness while resting. Some marine mammals, like sperm whales and elephant seals, engage in short bouts of sleep underwater, with sperm whales sleeping upright for about 20 minutes at a time and elephant seals entering rapid eye movement (REM) sleep while upside down and spinning in a slow circle. These adaptations allow marine mammals to rest while minimizing the risks of predation and heat loss in the open water.

Virginia Beach Police Investigate Mysterious Underwater Car Crash

A car mysteriously sped off a Virginia Beach pier and submerged in the Atlantic, with officials uncertain if anyone was inside. The vehicle was found upside down 17 feet below the surface, but rough conditions have hindered recovery efforts and the determination of potential occupants. Eerie footage captured by a passerby and a remotely operated vehicle (ROV) shows the car rocking in murky water, while strong currents and low visibility have made it too dangerous for divers to navigate and assess the area. Recovery efforts have been postponed due to violent waves, and the salvage crew will determine when it will be safe to continue.

"Enormous Dinosaur-Era Superstructure Unveiled in Pacific Ocean"

A massive Pacific plateau called the Melanesian Border Plateau, larger than the US state of Idaho, has been discovered on the sea floor near Fiji, with evidence suggesting it has formed through four separate pulses of volcanism since the age of dinosaurs. The plateau began forming 120 million years ago and continues to grow, challenging previous assumptions about the origins of underwater volcanic features.

"Breakthrough: Superhydrophobic Surface Stays Dry for Months Underwater"

Researchers have developed a superhydrophobic surface with a stable plastron that can last for months underwater. The surface, made from a titanium alloy, repels blood and prevents the adhesion of bacterial and marine organisms. This breakthrough opens up possibilities for applications in biomedicine and industry, such as reducing infection after surgery and preventing corrosion in pipelines and sensors. The surface survived 208 days submerged in water and significantly reduced the growth of E.coli and barnacles. The stability and scalability of this system make it valuable for real-world applications.

Unveiling Zealandia: The Long-Lost 8th Continent Resurfaces

Zealandia, the world's eighth continent, has been largely submerged underwater for the past 25 million years. Scientists have recently released the most accurate map of Zealandia, uncovering its geology and shedding light on its formation. Zealandia is believed to have formed around 83 million years ago when the supercontinent of Gondwana started to break up. It was stretched and pulled apart by tectonic forces, creating ruptures that later became oceanic crust. The study also revealed that Zealandia and West Antarctica were once connected. However, due to its underwater nature, much of Zealandia's secrets are still unknown.

Unveiling Zealandia: Scientists Uncover Earth's Hidden Eighth Continent

Scientists have analyzed samples from Zealandia, the submerged continent that separated from Gondwana 60 million years ago. Zealandia's crust is mostly underwater, with only a small portion, including New Zealand and New Caledonia, above water. The continent's crust is thinner than most continents but thicker than oceanic crust. The new research aims to understand the thinning process that caused Zealandia to sink. Evidence suggests that Zealandia was once home to a diverse range of plants and animals, providing insights into the dispersal and evolution of species in the South Pacific.

Masters of Deception: Trumpetfish Harness Camouflage to Ambush Prey

Trumpetfish have been observed using other species of fish as camouflage to approach their prey undetected. Researchers from the University of Cambridge created 3D models of trumpetfish and parrotfish to study this behavior. When the model of the trumpetfish was attached to the side of the parrotfish model, the prey fish inspected the models for a shorter duration and fled only when the models were closer. This shadowing behavior allows trumpetfish to reduce detection by their prey and approach closer before provoking an avoidance response. The study provides insights into how animals achieve concealment and highlights the potential impact of coral reef degradation on animal behavior.

Titan Submersible Safety Concerns Resurface After Recent Dive

A resident of Rochester, Aaron Newman, who was on the same "Titan" submersible two years ago, says those on the craft knew the risks they were taking when they signed up. Newman compared the trip to what it would be like to go to the moon, saying within three minutes, passengers are in complete darkness. He says while on his trip, he was able to see the stern of the Titanic. Newman hopes exploration doesn't stop after this trip, adding there's so much humanity needs to learn about the bottom of the ocean.

Possible Positive Sign: 'Banging' Sounds Detected in Search for Missing Titan Submersible.

Banging sounds have been detected underwater near where the Titan submersible went missing while on its way to view wreckage from the Titanic. The Canadian officials on board a specialized aircraft were the ones that detected the banging underwater. The news comes as there is less than 30 hours of breathable air left. The Joint Rescue Coordination Centre is working to find an underwater remote-operated vehicle through partner organizations to possibly assist. The Titan weighs 23,000 pounds and can reach a depth of nearly 2.5 miles underwater.
