A 4.45 billion-year-old zircon grain, extracted from a Martian meteorite, that was found in the Sahara in 2011, has revealed new details about the Red Planet's past. The study, conducted by researchers from Perth's Curtin University, indicates that Mars once had boiling hydrothermal systems like Earth's volcanoes. This also means that the planet may have been habitable at some point in its history and could have supported microbial life. 'Black Beauty' meteorite offers unique insights The research team analyzed meteorites from a space rock named NWA7034, or 'Black Beauty.' Unlike most Martian meteorites, which are mostly igneous or mantle rocks, these offer unique insights into Mars's geological history. Aaron Cavosie, a planetary scientist from Curtin University's Space Science and Technology Centre in Australia, said Black Beauty is unique as it is a regolith sample from Mars's surface and contains hundreds of rock and mineral fragments from different sources across the planet. Zircon grain analysis reveals hot water on Mars About 20 meteorites discovered on Earth are thought to have come from Mars during the impact that brought the original Black Beauty stone here. A minuscule zircon grain inside one of these meteorites, studied for the first time in 2022, provided clues about Mars's early crust formation and preserved evidence of past meteorite impacts. Cavosie said these meteorites offer valuable clues to reconstruct Mars's geological history. Element patterns hint at Mars's early history The research team studied the Martian zircon grain's trace elements to gain insight into its early history. Researchers used nano-scale geochemistry to uncover evidence of hot water on Mars 4.45 billion years ago. They also detected element patterns in zircon, like sodium, iron, yttrium, as well as aluminum. These patterns revealed that these elements were incorporated into the grain as it grew. "Hydrothermal systems were essential for life on Earth and our findings suggest Mars also had water," Cavosie said.
NEW YORK — The man accused of shooting and killing the CEO of UnitedHealthcare pleaded not guilty Monday to state murder and terror charges while his attorney complained that comments coming from New York’s mayor would make it tough to receive a fair trial. Luigi Mangione, 26, was shackled and seated in a Manhattan court when he leaned over to a microphone to enter his plea. The Manhattan district attorney charged him last week with multiple counts of murder, including murder as an act of terrorism. Mangione’s initial appearance in New York’s state trial court was preempted by federal prosecutors bringing their own charges over the shooting. The federal charges could carry the possibility of the death penalty, while the maximum sentence for the state charges is life in prison without parole. Prosecutors say the two cases will proceed on parallel tracks, with the state charges expected to go to trial first. One of Mangione’s attorneys told a judge that government officials, including New York Mayor Eric Adams, turned Mangione into a political pawn, robbing him of his rights as a defendant and tainting the jury pool. “I am very concerned about my client’s right to a fair trial,” Karen Friedman Agnifilo said. Adams and Police Commissioner Jessica Tisch stood among a throng of heavily armed officers Thursday when Mangione was flown to a Manhattan heliport and escorted up a pier after being extradited from Pennsylvania. Friedman Agnifilo said police turned Mangione’s return to New York into a choreographed spectacle. Adams is himself scheduled to stand trial on federal corruption charges next year. He pleaded not guilty and vowed to remain in office as he fights the charges. Authorities say Mangione gunned down Brian Thompson as he was walking to an investor conference in midtown Manhattan on the morning of Dec 4. Mangione was arrested in a Pennsylvania McDonald’s after a five-day search, carrying a gun that matched the one used in the shooting and a fake ID, police said. Mangione is being held in a Brooklyn federal jail alongside several other high-profile defendants, including Sean “Diddy” Combs and Sam Bankman-Fried. Get local news delivered to your inbox!

In just a few years, Nvidia ( NVDA -3.22% ) has accomplished a lot. The company went from primarily serving the video-gaming market with its chips and generating less than $5 billion in annual revenue to a position as artificial intelligence (AI) chip leader. This dominance is helping Nvidia bring in more revenue in just one quarter than it used to generate in a whole year. Revenue climbed 94% to a record of more than $35 billion in the recent three-month period. On top of this, Nvidia has scored other wins, such as entering the Dow Jones Industrial Average this year and soaring past Apple to become the world's most valuable company at more than $3.5 trillion. Now, moving forward, what's next for Nvidia? My prediction is one catalyst will help this AI powerhouse do something that no other company has ever done. From video games to artificial intelligence Before talking about my prediction, though, let's consider Nvidia's path so far. As mentioned, Nvidia used to mainly serve the video-games market with its high-performance graphics processing units (GPUs). But the GPU's ability to process many tasks at once meant it could be very useful elsewhere too; Nvidia's creation of parallel computing platform, CUDA, helped this transition happen. And as the AI boom picked up, it was clear that Nvidia's GPUs would play a major role in this high-growth industry. Nvidia went all in on AI, not only tailoring its GPUs to the needs of this newish technology but also providing a vast array of related products and services. This helped the company take more than 80% share in the AI chip market and position itself for victory over time. Today, Nvidia is the "go to" source for any player aiming to develop an AI project. And Nvidia counts the world's biggest technology companies as its major customers -- from Meta Platforms to Microsoft . It's also important to note that Nvidia's products and services are available across all public clouds, making it easy for customers to get in on Nvidia's AI offerings. All of this has led to triple-digit revenue growth quarter after quarter for the company's data center business and margins surpassing 70%. So not only is Nvidia winning when it comes to revenue growth, it's also winning when it comes to profitability on sales. Nvidia's stock performance has reflected this success story, with shares soaring 2,600% over the past five years -- and this year, they're heading for nearly a 200% increase. Nvidia's market value is set to rise Now, let's consider my prediction. I say that one catalyst right around the corner will help Nvidia do something that no other company has ever done. And that's to make it to a $4 trillion market capitalization . What's the catalyst? The company's launch of its new Blackwell architecture and best-performing chip ever. Nvidia already has sent out 13,000 Blackwell GPU samples to customers. And Microsoft and Oracle recently posted on social media, showing their new Blackwell-powered racks. Nvidia aims to ramp production in this current quarter and even bring in billions of dollars in revenue from Blackwell during the period. On top of this, Nvidia has spoken of "insane" demand for Blackwell, with this demand exceeding supply. This should drive growth for the company and please investors, so it could progressively push the stock higher. To get to a $4 trillion market cap, Nvidia's shares would have to rise about 13% to $165 from the price of about $146 as of the Nov. 21 market close. That's a clear possibility, considering the company's valuation today and growth prospects. Trading at 50 times forward earnings estimates , Nvidia isn't cheap, but it's reasonably priced for a high-growth player, allowing for room to run. Nvidia forecasts fourth-quarter revenue growth of about 70%. And analysts expect annual earnings-per-share growth of 35% over the coming five years. So, high demand for Blackwell -- a potentially game-changing platform -- along with Nvidia's valuation today make it possible for this company to do something no other company has done: reach $4 trillion in value. And whether this happens right away or at some point down the line, Nvidia, thanks to its leadership, commitment to innovation, and growth prospects, makes a top long-term AI buy.The British Columbia Hockey League hosted a special board of governors meeting this week to discuss ways to deal with the recent NCAA eligibility change, but one thing they didn't discuss was rejoining Hockey Canada. The league has seen a number of players depart the league this month for the Canadian Hockey League – or other major junior leagues – due to the NCAA's ruling on Nov. 7 that players suiting up in any of the three CHL leagues could continue on at the NCAA level. Prior to that decision, those who played in the CHL were not able to play at the NCAA level due to those leagues being considered semi-professional. The BCHL left Hockey Canada in 2023 and became an independent league. The mission at that time was to create a world-class junior league for players seeking NCAA and U Sports scholarships. It allowed the BCHL to recruit from a larger pool of players, as under Hockey Canada they could not recruit as heavily from other provinces and parts of the world. The BCHL also stated in 2023 that all player fees would be eliminated by the 2024-25 season. According to Jesse Adamson, the director of communications for the BCHL, discussions about linking back with Hockey Canada are not on the table. "Being an independent league puts us in a much better situation to handle this change as it gives our league the autonomy to make regulation changes to adapt to the new landscape," he told Black Press Media. "Our governors are still very happy with the decision to become independent." The BCHL issed a press release on Friday morning (Nov. 22), stating that only a small percentage of players have left the league and other players have been brought in to replace them. They also reiterated that the BCHL has always been about player choice. Unlike the CHL, the BCHL does not hold a draft or tell players where to play. Players are recruited and can choose their own destination from the start of their junior hockey career. "There’s no doubt that this rule change has altered the landscape of junior hockey, but as our league has always done, we will adapt to the new regulations and continue to thrive,” stated BCHL commissioner Steven Cocker. "We will always be in favour of athletes doing what they think is best for their development.” BCHL board chairman Richard Murphy said he believes that, despite the changing landscape, the BCHL is still the best path for players to develop into NCAA Division I hockey players. He added that the league will continue to produce college-bound athletes for years to come. The release stated that the BCHL’s mandate going forward remains: unity and growth, players' choice, academics, independence, and meeting the needs of its athletes and of NCAA Division I programs. following the meeting with more information. The FAQ states that the league has had multiple meetings with NCAA Division I programs and conferences and they all feel that this decision will not make the BCHL irrelevant. The FAQ added that the BCHL's high academic standards also makes players from the league more easy to recruit into the NCAA. , with the West Kelowna Warriors and Penticton Vees both losing two. The Vees put out a statement on Friday (Nov. 22) after losing forward Casey Brown and defenceman Julien Wasmer to the CHL. “Casey came to us with a personal issue. He felt being closer to his family would be best and we fully support and respect his decision. We wish him all the best in Moose Jaw," said Fred Harbinson, Vees president, general manager and head coach "We are a few weeks away from getting two 20-year-old defencemen back from injury, and coupled with the outstanding play of our two young defencemen, Julien understood his role was going to be reduced. He looked for an opportunity with another team, rather than compete for a more favourable spot on our roster." Other players who have moved on since the decision include: Lukas McCloskey (Vernon Vipers), Robin Benoit (Sherwood Park Crusaders), Linden Burrett (Cowichan Valley Capitals), Thomas Belzil (Powell River Kings) and Liam Beamish (Salmon Arm Silverbacks).
