Four years of Gepard in Ukraine: How the vintage German weapon is proving its worth

Four years of Gepard in Ukraine: How the vintage German weapon is proving its worth

Germany announced the delivery of Gepard self-propelled anti-aircraft guns to Ukraine shortly after Russia’s full-scale invasion four years ago, marking the first heavy weapons of Western design that Berlin supplied from its own stocks. On 26 April 2022, Defence Minister Christine Lambrecht confirmed the decision on the sidelines of a meeting of around 40 supporting states at Ramstein airbase. The systems came from industrial stocks and the export had been approved the day before, Lambrecht said at the time. Germany has since delivered at least 55 Gepard systems to Ukraine, where they have become an integral part of the country’s air defence. The announcement came shortly after Russian massacres in Bucha became known following the town’s liberation by Ukrainian forces at the end of March 2022. Before the start of Russia’s full-scale invasion, Germany had offered to supply 5,000 helmets to Ukraine — a response that drew widespread criticism. The Gepard was the first heavy weaponry Germany delivered without a so-called ring exchange, in which Berlin would supply weapons to a third country that would …

Scientists are close to proving that primordial black holes exist

Scientists are close to proving that primordial black holes exist

On November 12, 2025, three gravitational-wave detectors on two continents caught a ripple in spacetime. This event did not fit neatly into the usual story of how black holes form. The signal, labeled S251112cm, appears to have come from a merger involving at least one object lighter than the sun. That is the part that stands out. Black holes formed from collapsing stars are not expected to be that small. If the signal holds up, it may point to something far stranger. For example, it could indicate a black hole born in the early universe itself. That possibility sits at the center of a new study from the University of Miami. Physicist Nico Cappelluti and doctoral student Alberto Magaraggia argue that the event matches what researchers would expect from a primordial black hole. Such an object may have formed in the dense chaos shortly after the Big Bang. In addition, it could help explain dark matter. “Our research indicates that these primordial black holes could account for a significant portion, if not all, of dark …

Astrophysicists are close to proving the existence of primordial black holes

On November 12, 2025, a ripple passed through the fabric of spacetime and triggered alarms at three gravitational-wave observatories across two continents. The signal, catalogued as S251112cm, was unusual in a way that stopped astrophysicists cold: at least one of the objects that created it appeared to weigh less than the sun. No known stellar process produces a black hole that small. Stars that collapse into black holes leave remnants several times the sun’s mass, at minimum. Something lighter has only one plausible origin, an object that formed not from a dying star but from the raw density of the universe itself, fractions of a second after the Big Bang. Two researchers at the University of Miami believe they now have a framework to explain what LIGO may have found. The case for a primordial origin Nico Cappelluti, an associate professor in the Department of Physics, and Ph.D. student Alberto Magaraggia have published research in the Astrophysical Journal building a quantitative case that the November signal is consistent with a primordial black hole, a class …

The US regional dailies proving news can pay despite Washington Post challenges

The US regional dailies proving news can pay despite Washington Post challenges

The Washington Post building. Picture: Shutterstock/Phil Pasquini The Washington Post’s evisceration at the hands of its billionaire owner, Amazon founder Jeff Bezos, didn’t have to happen. Following months of speculation, the Post cut at least 300 of its 800 journalists on Feb. 4, 2026, drastically reducing its international, local and sports coverage and eliminating its photo department and stand-alone book review section. The downsizing followed several decisions by Bezos that drove away hundreds of thousands of subscribers, from killing the Post’s endorsement of Democratic presidential nominee Kamala Harris just before the 2024 election to announcing that the editorial pages would henceforth be dedicated to “personal liberties and free markets.” But though those moves inflicted considerable damage, the paper had been floundering ever since Donald Trump’s first presidential term, when Bezos proudly added the slogan “Democracy Dies in Darkness” to its nameplate and the paper achieved both growth and profitability. While its principal rival, The New York Times, successfully pivoted by rolling out ancillary products such as games, a cooking app and a consumer guide, the …

Uniqlo’s Top-Dog Designer Keeps Proving Why She Got the Job

Uniqlo’s Top-Dog Designer Keeps Proving Why She Got the Job

It’s an inopportune time to consider spring’s arrival given the weather outside right now, but when there’s new Uniqlo : C product on the shelves, concepts like “spring’s arrival” feel a bit less theoretical—and a lot less daunting. So on that note, I have great news: there’s new Uniqlo : C product on the shelves, which means means the fastest way to look maximally elegant with minimal fuss is back in typically exquisite fashion. For anybody who might benefit from a refresher—understandable, considering it’s been a few months since the last drop—Uniqlo : C is the Japanese retailer’s latest sub-label, helmed by industry veteran Clare Waight Keller, whose CV includes stints at Chloé, Gucci, Ralph Lauren, and more. Her work for Uniqlo : C has been exceptional from the jump, prompting the company to expand its remit to include menswear a few seasons back. The latest drop is tight in both the range of the assortment and the strength of the pieces that comprise it. Pretty much every item can either carry an outfit or …

Ice hockey proving the hottest ticket as sales approach 1.2 million

Ice hockey proving the hottest ticket as sales approach 1.2 million

MILAN, Feb 2 : Almost 1.2 million tickets have been sold for the Milano Cortina Winter Olympics and the Paralympics, local organisers said on Monday, with ice hockey topping the list. That figure represents around 75 per cent of the total capacity for the Games which open on Friday and will be followed by the Paralympics next month. The ice hockey will feature players from the North American NHL for the first time since 2014. Organisers are rushing to get the new Santagiulia ice hockey stadium in Milan ready in time for the Games. The opening ceremony of the Games will be held in Milan’s historic San Siro soccer stadium on Friday but the sporting action begins as early as Wednesday. Fans will be able to buy two tickets for the price of one for some of the events being staged between Wednesday and Friday, in a promotion announced on Monday. These include curling in Cortina d’Ampezzo, the Sweden v Germany women’s ice hockey match in Milan, and men’s big air snowboard qualification in the …

Kremlin Makes Show Of Handing Evidence To US Side ‘Proving’ Ukrainian Attack On Putin Residence

Kremlin Makes Show Of Handing Evidence To US Side ‘Proving’ Ukrainian Attack On Putin Residence

The Kremlin has really made a big show for the cameras of handing over to American officials what it says is evidence that Ukrainian drones had attempted to strike Russian President Vladimir Putin’s residence in the Novgorod region Sunday night into Monday morning. The international community has asked for evidence Putin’s residence was targeted, and Moscow has responded. Footage released by the Russian Defense Ministry on Thursday shows Igor Kostykov, head of the Main Intelligence Directorate of the Russian General Staff, meeting with the US defense attaché in Moscow and handing over what he identified as a “navigation unit” recovered from one of the drones shot down in Novgorod. Russia has been on an information blitz, putting out images of downed drones and televised interviews of local Russian eyewitnesses to the drone waves early this week. But the ‘evidence hand-over’ to the US side is ultimately strong signaling aimed at President Trump. Kostykov described that the “decryption of the content of the memory of the navigation controller of the drones carried out by specialists of Russia’s special …

The essential guide to proving we’ve found alien life

The essential guide to proving we’ve found alien life

The afternoon of 7 August 1996 isn’t a time that sticks in many people’s minds. But if things had worked out differently, it might have been etched into our collective memory. At 1.15pm, US President Bill Clinton stepped onto the White House’s verdant South Lawn to speak about the possible detection of life in a Martian meteorite. “If this discovery is confirmed, it will surely be one of the most stunning insights into our universe that science has ever uncovered,” he said. But it wasn’t: it joined a list of inconclusive claims about alien life. We don’t, of course, have to go all the way back to the 1990s to find other such claims – just a few years ago, the discovery of phosphine gas in the atmosphere of Venus got scientists excited. And in 2017, Avi Loeb at Harvard University said the interstellar object ʻOumuamua was a piece of alien technology. With a slew of new missions poised to return data from alien worlds, the pace of these potential discoveries is likely to accelerate. So, …

Podcast: The Challenge of Proving Creativity in AI

Podcast: The Challenge of Proving Creativity in AI

In a recent episode of the Mind Matters podcast, host Robert J. Marks sat down with Dr. Georgios Mappouras to discuss his new paper, The Turing Test 2.0: The General Intelligence Threshold. In the paper, Mappouras proposes a modern update to the Turing Test. That was Alan Turing’s classic 1950 test for machine intelligence. His goal is to design a more precise way to determine whether an artificial intelligence (AI) system can truly think — and more important, whether it can be creative. Turing’s original test judged intelligence by competence in conversation: if a human could not tell whether a conversation partner was a person or a machine, the AI would “pass.” But as language models like ChatGPT grow more sophisticated, the line between imitation and genuine thought becomes blurry. Mappouras’s Turing Test 2.0 aims to go deeper by focusing on functionality and creativity, not just successful imitation. The Lovelace Test and the problem of surprise In the third part of the conversation, Marks compared Mappouras’s proposal to the Lovelace Test, introduced by cognitive scientist Selmer …
