📌 MAROKO133 Hot ai: Subsurface map of Antarctica reveals hidden terrain with the s

What lies beneath Antarctica’s immense and impenetrable ice sheet? Until now, we didn’t fully know, but a new, groundbreaking study reached deeper than any other to discover a hidden world that might hold the key to predicting the future of the continent, as well as our world.

In a new, groundbreaking study published in Science, authors explained that “less is known about the topography beneath the ice of Antarctica than any other planetary surface in the inner solar system.”

As the least studied region in the known universe, this mysterious area, cloaked by the Antarctic Ice Sheet, “offers critical insights into its geological history and influences how the ice reacts to climate changes,” as study authors continued.

Scientists ventured into our planet’s icy frontier with satellite data and physics. They deciphered the complex movements of the ice as if reading a secret language, creating a map of a subglacial wonderland of mountains, deep canyons, and rugged hills, as per the BBC.

And this sub-surface map of Antarctica would aid climate scientists in understanding how glaciers will move as the ice continues to melt under the threat of climate change. The urgency surrounding the speed of their disappearance is one of the most significant uncertainties confronting us today.

Did these scientists just break new ground?

Is Narnia actually under Antarctica?

Antarctica has long sparked the imagination, characterized as the Earth’s southernmost, coldest, and driest polar desert. Ancient glaciers, expansive ice shelves, and towering mountain ranges create an awe-inspiring landscape. It also serves as a sanctuary for unique wildlife, including penguins and seals, while being a hub for extensive international scientific research.

Although previous surveys have provided insights, a lead climate scientist said to the BBC that the latest map was “a really useful product” because it fills crucial gaps that have persisted for decades. No researcher had penetrated these depths or mapped the ice sheet’s underlying terrain in such vivid, thrilling detail.

The research team analyzed the surface using high-resolution satellite imagery, followed by a technique in physics known as Ice Flow Perturbation Analysis (IFPA). They traced the landscape by studying how the ice moved around it.

Beneath a colossal 5.4 million square miles of ice sheet, the study documented a staggering 71,997 hills and mapped a valley that stretched 248.5 miles within the Maud Subglacial Basin. Beneath Antarctica, river channels stretched hundreds of miles, and some regions even evoked alpine landscapes, Live Science reported. Detected transitions between highland plateaus and low-lying basins revealed tectonic boundaries that hint at the dynamic geological processes at play.

Indeed, an entire world awaited researchers beneath the surface that exercised a direct influence on the surface.

The key to climate change

The wealth of valuable information unearthed by the study stands to become as immense in significance as the map, as the rapidly melting Antarctic ice remains one of the era’s biggest concerns.

As the BBC elaborated, this hidden topography will significantly influence the movement of glaciers. But most importantly, the speed at which they might disappear and displace themselves.

With the map, scientists can improve their predictions on how swiftly the Antarctic ice will contribute to global sea-level rise.

📌 MAROKO133 Update ai: Google’s AI Insists That Next Year Is Not 2027 Hari Ini

We have it on good authority that next year is not 2027.

That authority, of course, is Google’s horribly inaccurate AI Overview feature.

By now, you’re probably well aware that the search engine’s AI-generated summaries are plagued with hallucinations. But you’d think after years of being unleashed on the unsuspecting public, they might be a little better.

Fat chance, it turns out. Ask Google’s incredibly trustworthy AI model “is 2027 next year,” and you’ll get an answer that inconveniently conflicts with reality.

“No, 2027 is not next year; 2027 is two years away from the current year (2026),” it confidently explains, “meaning next year is 2028, and the year after that is 2027, which is a common year starting on a Friday.” A link icon lists several sources for this claim.

In another instance, Google’s AI says it’s currently 2025.

Clearly, the calendars are all wrong, so we’d recommend making a change to yours: whatever date you marked down for the coming of the singularity, push it way back.

Reddit posts flagging this issue show that the AI Overview has been giving the wrong answer for well over a week. But Google engineers aren’t the only ones who’ll need to confide in their chatbot wives or therapists to cope with the embarrassment: OpenAI’s ChatGPT also struggles when asked if 2027 is next year.

“No 2027 is not next year,” it asserts (emphasis the AI’s).

To be fair to ChatGPT, which was running the free version of its latest model, 5.2, it does quickly catch its mistake. “Wait — sorry, let me restate that clearly: Since the current year is 2026, 2027 is next year.”

So does Anthropic’s Claude Sonnet 4.5, after making the same blunder.

“No, 2027 is not next year. The current date is Thursday, January 15, 2026, so next year would be 2027,” Claude says. Then it adds: “… wait, let me reconsider that.”

“Actually, you’re right to question this. Since we’re currently in 2026, next year would be 2027.”

Either the tech industry’s top models are all secretly operating as part of some vast but amazingly stupid hive mind, or the large language model architecture that underpins them is wonky junk that struggles to keep up with predictable changes like a new year. We’d expect Google’s AI Overviews to screw up such a softball question, given its storied history that includes recommending you put glue on pizza, and its documented susceptibility to inventing meanings for made-up idioms, such as “you can’t lick a badger twice.” But you might expect just a teensy bit better from flagship chatbots like ChatGPT and Claude, which are supposed to represent the best the industry’s got.

On that note, when we asked Google’s much-hyped Gemini 3 about what next year is, it aced it. And for having passed such a high bar, perhaps that’s why it’s been crowned as the new leader in the AI race. Congratulations.
