Trail of ghostly crabs leads scientists to extraordinary underwater discovery
We’ve heard of following the yellow brick road, and even following the white rabbit, but scientists have just made a landmark discovery by following a trail of ghostly crabs. For some 20 years, experts believed there was a hydrothermal vent field off the western Galápagos Islands, but they hadn’t been able to pinpoint its exact location. However, while exploring the area they spotted a galatheid crab (also called a squat lobster), and then another, and then another. They traced the crustaceans excitedly as their number grew until, finally, they were led to the elusive hydrothermal goldmine. There are only around 550 known hydrothermal vents in the world, only half of which have actually been seen. The rest have been identified via chemical and temperature signatures in the surrounding water, as Live Science notes. Hydrothermal vents are formed when water seeps into the rock of the seafloor at either a plate margin or where magma is rising to the surface in another part of the plate. The magma heats the water, which causes it to rise, before it’s expelled through fissures in the rock, often forming what are known as chimneys. The new Galápagos field, discovered thanks to the crabs which aggregate around deep-sear vents, extends more than 98,800 square feet (9,178 square metres), and consists of five geyser-like chimneys and three hot springs. The highest temperature so far recorded there is a staggering 288C (550F). As well as the the geysers, hot springs and crabs, the team, from the Schmidt Ocean Institute, found a thriving ecosystem of incredibly adapted organisms. "There were giant tube worms, which can be a couple (of) metres long. There were very large clams, sometimes called dinner plate clams, as well as mussels," said Roxanne Beinart, a biological oceanographer who co-led the expedition. To locate the hydrothermal field, the researchers first began searching the general region where a chemical anomaly had been identified in 2008. "One of the anomalies that we look for is a lens of low oxygen water," expedition co-leader Jill McDermott, a chemical oceanographer at Lehigh University in Pennsylvania, told Live Science. "Oxygen is completely removed through circulation in the seafloor. So the water that's expressed at the seafloor is devoid of oxygen." The team then followed this plume of oxygen-poor water until it disappeared — implying they were close to the vent. They then launched a remotely operated vehicle to inspect the seafloor and traced the breadcrumb trail of crabs to the vent field itself. “With 75 per cent of the seafloor still to map, finding this new vent field shows how much we still have to learn about our planet and those who live on it,” the Schmidt Ocean Institute’s Executive Director Dr Jyotika Virmani said in a statement. “I am continually amazed by the otherworldly beauty of our seafloor and look forward to uncovering more.” And what did the team christen the new hydrothermal vent field? Why, the “Sendero del Cangrejo,” or “Trail of the Crabs,” of course. Sign up for our free Indy100 weekly newsletter Have your say in our news democracy.

Gareth Southgate pleased with England progress but ‘always room for improvement’
Gareth Southgate has been pleased by England’s progress during an unbeaten 2023 but knows there is work to do as the team tries to win the European Championship. The Euro 2020 runners-up are among the favourites to win in Germany next summer but seemed to lose their edge after sealing qualification with two matches to spare. Friday’s uninspiring 2-0 Wembley win against minnows Malta was followed three days later by an underwhelming 1-1 draw in North Macedonia as the curtain came down on an undefeated year. November’s double-header will not live long in the memory but Southgate has “learned a lot” from the fixtures, with attention now intensifying on his fourth – and possibly final – major tournament in the dugout. “We wanted to look at a few different things as well, so we’ve managed to learn from the game as well as the result,” the England boss said in Skopje. “I have to be pleased with the progress of the team. You know, if you’d said at the start of the campaign that we would be eight wins, two draws at the end of the year, it’s a pretty good record given the fixtures that we’ve had. “(North Macedonia) was always a game where we knew if you’d needed to come here for that point to qualify would be a very difficult place to come. They took the draw from Italy as well, so credit to North Macedonia for that. “We can now start to look forward. We’ve got these two exciting games in March to look forward to and prepare for. “So, yeah, I think we’ve done a lot of things well, but there’s always room for improvement.” March’s home friendlies against Brazil and Belgium will provide much-needed challenges in the final meet-up before Southgate selects his 23-man squad for Germany. Two further preparation games will follow before the Euros get under way, with the December 2 draw in Hamburg providing clarity on next summer’s opposition, base camp and potential route to the final. I think we've done a lot of things well, but there's always room for improvement. Gareth Southgate England’s draw against Macedonia rubber-stamped their place among the top seeds for the Euro 2024 draw and Southgate said: “In the calendar year we’re eight wins and two draws from a particularly tough qualifying group and certainly a friendly in Scotland that was always going to be challenging. “Of course, you’d like 10 wins out of 10 but not many teams do that. “I’m really pleased with what the players have given – not just the players that are here tonight, but the players that have represented us through this year because they’ve been excellent.” Harry Kane has, unsurprisingly, been among the standout performers this year but questions about the Bayern Munich sharpshooter’s back-up remain. Callum Wilson, Ivan Toney, Eddie Nketiah and Dominic Calvert-Lewin have all been selected in recent times, but Ollie Watkins is the current frontrunner for the job. The Aston Villa striker had the chance to underline that status against Macedonia but was replaced by Kane just 58 minutes into a frustrating night in Skopje, where the skipper made an immediate impact as he forced Jani Atanasov into an own goal equaliser. “Look, it was a difficult game,” Southgate said when asked about Watkins. “Very little space, back five, so we’re dealing with three centre-backs, really, and we weren’t quite able to create the clear chance for him. “But he did fine. It’s not easy when you’re coming in in those circumstances but that’s international football. “Of course, he’s had games where there’s been more opportunities to score and he’s done that well with us. “(This) was a different sort of test and, yeah, as a team, it was hard to find the spaces and find the gaps even though moments Phil (Foden) found lovely little passes and Trent (Alexander-Arnold) did. “It was so crowded around the edge of that box to find those clear chances for our forwards.” Read More Kyle Walker urges England to get mentality right in bid for Euro 2024 glory Phil Taylor to retire at the end of World Senior Darts Tour in 2024 On this day in 2007: England fail to qualify for Euro 2008 after Croatia defeat Jalen Hurts grabs double as Philadelphia Eagles avenge Super Bowl loss Gareth Southgate hails Rico Lewis after strong England debut in North Macedonia Michael O’Neill calls Northern Ireland win over Denmark step in right direction

Kyle Walker urges England to get mentality right in bid for Euro 2024 glory
Kyle Walker believes England have enough players with big-match experience to challenge for Euro 2024 glory – if they can perfect their mentality. England rounded off 2023 with a forgettable 1-1 draw in North Macedonia on Monday night having already assured their spot at next summer’s finals by beating Italy last month. Gareth Southgate’s side ended the calendar year unbeaten and topped Group C of Euro 2024 qualifying in the process. The Euro 2020 runners-up will now be top seeds for December’s group-stage draw in Hamburg as England target their first major silverware since 1966. Walker insists they ended the year well despite having already secured qualification amid criticism of the performances in North Macedonia and in the 2-0 Wembley win over Malta. “I don’t think there’s really been a drop off,” he told Radio 5Live. “There’s been a good win against Malta. Okay, if you go and score eight everyone says you should have gone and scored eight- if we don’t score eight it’s a problem. We're all mature, we've all been in big situations, Whether it's Champions League finals, fighting for the Premier League, semi-finals of a World Cup, finals of the Euros Kyle Walker “So it’s three points. Never mind if it’s an eight or 1-0, it is still three points on the board. We know coming here, we should win. We should win but the campaign and the group is wrapped up and it was always going to be a difficult one. “But I said at the start of the team talk that it’s about mentality now, we’ve got the group of players that we’ve had for a number of years now. We’re all mature, we’ve all been in big situations, whether it’s Champions League finals, fighting for the Premier League, semi-finals of a World Cup, finals of the Euros. “Now it’s about our mentality. Now it’s about mentality on the field and off the field to make sure that we take this country to where it deserves and that is to hopefully pick up that European trophy.” Walker, 33, has been installed as Manchester City captain this season but sported the armband for his country for the first time in Monday’s draw. “It was a really proud moment when the manager pulled me aside this afternoon and told me that I would be leading the team out,” he added. “Obviously I’m doing that for Manchester City now but to do it for my country is a real big step in the right direction and another thing I’ve ticked off my list. “We had to be patient and try and break them down. They had a back five and it’s always going to be tough but that’s no excuse. “We know that we should be coming here, taking three points and getting on the plane back home and celebrating qualifying with a good end to the campaign. “But listen, we’ve qualified and let’s not underestimate that. We’ve qualified for a major tournament once again and that’s what we needed to really do.” Read More Phil Taylor to retire at the end of World Senior Darts Tour in 2024 On this day in 2007: England fail to qualify for Euro 2008 after Croatia defeat Jalen Hurts grabs double as Philadelphia Eagles avenge Super Bowl loss Gareth Southgate hails Rico Lewis after strong England debut in North Macedonia Michael O’Neill calls Northern Ireland win over Denmark step in right direction Rob Page: Wales not entertaining Euro 2024 play-off talk before Turkey qualifier

Microsoft stock hits all-time high after hiring former OpenAI CEO Sam Altman
Microsoft stock has hit a record high after hiring sacked OpenAI boss Sam Altman and other key figures from the AI firm. The US tech giant, which is a key investor in OpenAI, is the second most valuable company in the world behind Apple. The firm’s market cap on 21 November reached above $2.8 trillion – up $1 trillion since the start of the year. Microsoft chief executive Satya Nadella announced that Mr Altman, who headed ChatGPT creator OpenAI until he was ousted on Friday, would join Microsoft to lead a new advanced AI research team alongside fellow OpenAI co-founder Greg Brockman “We’re extremely excited to share the news that Sam Altman and Greg Brockman, together with colleagues, will be joining Microsoft to lead a new advanced AI research team,” Mr Nadella wrote on X, formerly Twitter. “We look forward to moving quickly to provide them with the resources needed for their success.” Despite his new role, Mr Altman is reportedly keen on returning to his former company following a revolt among OpenAI employees against the board. More than 700 OpenAI workers signed a letter threatening to quit unless the board resigns and reappoints Mr Altman as chief executive. “The process through which you terminated Sam Altman and removed Greg Brockman from the board has jeopardised all of this work and undermined our mission and company,” the open letter stated. “Your conduct has made it clear you did not have the competence to oversee OpenAI.” OpenAI board member Ilya Sutskever said on Monday that he “deeply regrets” his role in Mr Altman’s sacking, adding that he was now working to reunite the company. Following his exit from OpenAI last week, Mr Altman wrote on X: “I loved my time at OpenAI. It was transformative for me personally, and hopefully the world a little bit. Most of all I loved working with such talented people. Will have more to say about what’s next later.” After rumours emerged that he was looking to rejoin his former company after being hired by Microsoft, Mr Altman wrote: “Satya [Nadella] and my top priority remains to ensure OpenAI continues to thrive. “We are committed to fully providing continuity of operations to our partners and customers. The OpenAI/ Microsoft partnership makes this very doable.” Read More Microsoft chief hints Sam Altman may return as OpenAI staff demand board resignation OpenAI staff ‘threaten to quit over ousting of Sam Altman’ Microsoft’s new AI tool cleans up messy backgrounds in video calls
