An enormous iceberg in Antarctica — an ice slab that’s so massive, it has a surface area greater than Los Angeles — recently got its first aerial cameo, which showed off its mind blowing size.
The ice slab, named A81, was birthed from the Brunt Ice Shelf on Jan. 22 after a gigantic chasm finally snapped through the 490-foot-thick (150 meters) ice shelf, after having been widening for nearly a decade. A81 covered an area of around 600 square miles (1,550 square kilometers) when it broke free from Antarctica and has since traveled around 93 miles (150 km) into the Weddell Sea.
Researchers from the British Antarctic Survey’s (BAS) Halley Research Station captured the footage of A81 as they flew over the iceberg on their journey home. The video, released March 13, shows the enormous scale of the hefty berg, which looks like its own ice sheet and is birthing tiny icebergs along its coastline.

The Halley Research Station was previously based on the ice that now makes up A81 but was moved further inland after the chasm was spotted.
“This was a calving [event] we knew was coming,” Oliver Marsh (opens in new tab) , a BAS glaciologist who recently returned from the Halley Research Station, said in a statement (opens in new tab) . The BAS team first noticed the chasm in 2012 and has been expecting the immense chunk of ice to break off ever since, he added.

BAS researchers will continue to track A81 to see where it will end up and what impact it may have on sea levels when it finally melts away.
Glaciologists are also keeping a close eye on another giant iceberg, A76A, which broke off from Antarctica’s Ronne Ice Shelf in May 2021. The mammoth slab of ice is the biggest iceberg on the planet and the largest remaining piece of A76, which covered an area of around 1,700 square miles (4,300 square km), or larger than the state of Rhode Island, when it calved from the ice sheet. On Oct. 31, 2022, satellite images revealed A76A had finally started to drift away from Antarctica’s coastline and into the Drake Passage, which will drag the berg toward the equator where it will eventually melt.
Donald Trump has announced his “highly anticipated” meeting with Vladimir Putin will take place next Friday in the US state of Alaska.
The two presidents are expected to discuss the war in Ukraine – with the talks potentially leading to a breakthrough in Mr Trump’s effort to end the conflict.
But there’s no guarantee it will stop the fighting since Moscow and Kyiv remain far apart on their conditions for peace.
Earlier, the US president told reporters “we’re getting very close to a deal” that would end the war.
Mr Trump added there will be “some swapping of territories to the betterment of both sides”.

‘I’m not against meeting Zelenskyy’
The meeting between the two leaders will be the first US-Russia summit since 2021, when former US President Joe Biden met Mr Putin in Switzerland.

Mr Trump wrote on Truth Social: “The highly anticipated meeting between myself, as President of the United States of America, and President Vladimir Putin, of Russia, will take place next Friday, August 15, 2025, in the Great State of Alaska. Further details to follow. Thank you for your attention to this matter!”
The meeting was also confirmed by Kremlin aide Yury Ushakov, who said the leaders will “focus on discussing options for achieving a long-term peaceful resolution to the Ukrainian crisis”.
He added that the two presidents could meet in Russia in future and that an invitation has already been extended to Mr Trump.

Yesterday, Mr Trump had told reporters at the White House that he couldn’t announce where or when the meeting would take place but he would do so soon.
He also suggested that his meeting with the Russian leader could come before any discussion involving Ukrainian President Volodymyr Zelenskyy.
“We’re going to have a meeting with Russia, start off with Russia. And we’ll announce a location. I think the location will be a very popular one,” Mr Trump said.
The US president added: “President Putin, I believe, wants to see peace, and Zelenskyy wants to see peace … in all fairness to President Zelenskyy, he’s getting everything he needs to, assuming we get something done.”

Territory to form part of talks
Speaking about the role that territory will play in the peace talks, Mr Trump said: “You’re looking at a territory that’s been fought over for three-and-a-half years. A lot of Russians have died. A lot of Ukrainians have died.
“So we’re looking at that, but we’re actually looking to get some back, and some swapping.
“It’s complicated, actually. Nothing is easy. It’s very complicated. But we’re going to get some back.
“We’re going to get some switched. There’ll be some swapping of territories to the betterment of both.”
Analysts, including some close to the Kremlin, have suggested that Russia could offer to give up territory it controls outside of the four regions it claims to have annexed.
Pressed on if this was the last chance to make a major peace deal, Mr Trump said: “I don’t like using the term last chance … when those guns start going off, it’s awfully tough to get them to stop.”

Trump says he will meet Putin
Western officials ‘to meet in UK’
Meanwhile, senior officials from the US, Ukraine and several European countries are due to meet in the UK this weekend to try and reach common positions ahead of the Trump-Putin meeting, according to Axios.
Ukraine and several NATO allies are reported to be privately concerned that Mr Trump might agree to Mr Putin’s proposals for ending the war without taking their positions into consideration.
Since his return to the White House in January, Mr Trump has moved to mend relations with Russia and sought to end the war – with public comments veering between admiration and sharp criticism of Mr Putin.
In a sign of his growing frustration with Russia’s refusal to halt its military offensive, Mr Trump had threatened to impose new sanctions and tariffs against Moscow – and countries that buy its exports – unless the Kremlin agreed to end the conflict.
A deadline was set for yesterday, but it is unclear whether these sanctions are taking effect, or if they will be delayed or cancelled in light of the talks.

War grinds on ahead of talks
The meeting has been arranged as Russia’s bigger army is slowly advancing deeper into Ukraine at great cost in troops and armour while it relentlessly bombards Ukrainian cities.
Ukrainian forces are locked in intense battles along the 620-mile frontline that snakes from northeast to southeast Ukraine.
The Pokrovsk area of the eastern Donetsk region is taking the brunt of punishment as Russia seeks to break out into the neighbouring Dnipropetrovsk region.

Chris Hemsworth has told Sky News that finding out he had a greater chance of developing Alzheimer’s disease was a “gear shift” in his life motivations.
During a genetic test in season one of Limitless: Live Better Now, the Australian actor discovered that he is, biologically, eight to 10 times more likely than others to have the brain disorder during his lifetime as he carries two copies of the APOE4 gene.
He had first taken part in the National Geographic show to be its “guinea pig” and face new experiences that challenge the body and mind.
But after having the test, the 41-year-old Thor, Furiosa and Transformers star was faced with an unexpected truth.

One in every 50 people inherit two copies of the APOE4 gene and research has found that nearly all double carriers showed key early signs of the disease which causes dementia by the age of 55.
Everyone’s risk is different, and evidence suggests there are things you can do to reduce your risk whether you’re a carrier of the gene or not, including not smoking, reducing alcohol intake, daily exercise, monitoring cholesterol and blood pressure and eating a balanced diet.
Speaking of when he found out he was a double carrier, Hemsworth told Sky News: “It was just kind of this point in my life where up until your 40s, you’re kind of gathering data and information and it’s all reactionary and then you get to a point where you think, oh some of this sort of identity that I’ve sort of built doesn’t hold true anymore.

“There’s some inner sort of protest or inner voice that has a deeper need to understand and there’s deeper questions and what is the purpose and the why behind what I’m doing … and what am I seeking, what am I contributing, as opposed to just what I am collecting.”
Reacting on screen, he said it made him shift his focus to living better and increase the chances of him spending as much time as possible with his family and friends.

What’s changed in the second series?
The change in mindset is evident in season two.
“This time around, I was very involved in the orchestration and the sort of production and bringing together spaces that I was interested in or there was a deep curiosity or were deeply personal to me. And it was more sort of experiential journalism as opposed to a contestant in a challenging kind of fun, reality show.
He adds: “I was much more committed or invested in the experience.
“And I was a bit more educated on the topics too. I had to research, I had a deeper point of view, I suppose, personally, but also sort of the education I was given prior and I enjoyed that more, to be honest, I didn’t like that I felt very uncomfortable in the first season because I was standing around all these experts and I knew nothing about these topics, yet I was kind of asked to speak on them and so I felt like an imposter the entire time.”
Limitless: Live Better Now looks at the ways in which you can improve your brain and body’s health through endurance challenges and learning a new instrument.

Teaming up with Sheeran
Hemsworth chose the drums and, taking it to the extreme, was set the task of joining his friend Ed Sheeran on stage to play Thinking Out Loud.
“That fear and that anxiety was incredibly overwhelming,” Hemsworth says, detailing how he felt “underwater” in the weeks leading up to the event.
“It’s weird the way intense situations actually cause a hyper focus; it’s a survival mechanism of the brain.
“Some of the other challenges where if I did the training it was beneficial, but I could kind of muscle my way through it. You can’t do that with a musical instrument and then the realisation that the entire band is relying on you to keep time. And then 70,000 people are sitting there going, ‘please don’t wreck our favourite song’.”
Reflecting on the moment, he says it’s one of the most magical feelings he’s ever had.
“The joy was unlike anything I’ve ever experienced. You know, if you could bottle that and have it in a healthy way and not have all the negatives that someone may have for it, it was amazing. It was a true kind of one of my first probably proper out of body experiences, I suppose.
“It was like, I kind of remember being in the out, looking down at myself almost, kind of going, wow, I’m kind of floating along with this thing that’s so much bigger than me and I’m in true sort of flow state with it.”
National Geographic’s Limitless: Live Better Now is available to stream on Disney+ from 15 August.
