Viktor Gyökeres has articulated the hurt and defiance within the Arsenal dressing room following their 2-0 Carabao Cup final defeat by Manchester City and promised to use it as fuel in the club's pursuit of other trophies this season.Arsenal produced their worst performance of the season in the final, with nearly every player falling below their standard – with the possible exception of William Saliba. The period from the beginning of the second half until Nico O'Reilly scored his second goal in the 64th minute proved particularly difficult, as City established complete dominance, leaving Arsenal pinned back and struggling to mount any meaningful attack.The recovery mission has already begun, with some at the club hoping the international break will provide a timely change of environment and focus. For Gyökeres, there is also the matter of Thursday's World Cup playoff with Sweden against Ukraine in Valencia. If his country advances, they will face Poland or Albania next Tuesday for a place at the finals.Despite the setback, Arsenal remains nine points clear of City at the top of the Premier League, albeit having played one game more, and has progressed to the Champions League quarter-finals, where they will face Sporting. Their next domestic challenge comes in the FA Cup quarter-final at Southampton on the following Saturday."Of course, we don't feel great right now but it's not like we have a game in three days," Gyökeres said. "For sure, we will go again and be even more motivated for those games."The turning point at Wembley came when Arsenal's backup goalkeeper Kepa Arrizabalaga – who Mikel Arteta started ahead of first-choice David Raya – dropped a cross to allow O'Reilly to score his first goal, although City had already established firm control of possession."We created some chances at the beginning of the game and then I think it was maybe 10 minutes from the break where they got the momentum," Gyökeres reflected. "I think they had the ball … maybe they didn't create so many dangerous chances but they had the ball a long time and it looked the same in the second half."Normally, when it's two top teams it can be like that [with the first goal being crucial]. In the moment of the game where they scored … yeah, it was difficult to get going afterwards."

Satellite images of Tehran have revealed that toxic fires caused by Israeli bombings on oil depots were still burning days after the strikes, posing serious health risks to millions of residents in the Iranian capital.The bombings, which occurred on March 7, caused clouds of smoke to blanket the city with pollutants ranging from soot to oil particles to sulphur dioxide. A passing storm then showered Tehran with poisonous, oil-filled rain.Residents have reported headaches, eye and skin irritation, and difficulty breathing. Experts have warned that these symptoms could be just the beginning, with long-term risks of cardiovascular disease, cognitive impairment, DNA damage, and cancer.Four fuel facilities in and around the capital were hit, including the Shahran depot in the north-west, the Aqdasieh oil depot in the north-east, the Tehran refinery in the south, and the Shahid Dolati facility in the west.Satellite images taken two days after the strikes showed the Shahran depot and the Tehran refinery were still burning. Another image taken by the European Space Agency satellite on Tuesday – 10 days after the strikes – showed that those two fires had smouldered, but smoke and flames were visible at the Aqdasieh oil depot.Iran has described the attacks as “ecocide”, which is described as wanton acts of environmental destruction.The United Nations Environment Programme (UNEP) has warned that heavy smoke from burning oil was “directly inhaled by people in Iran – including young children – raising serious concerns about long-term impacts on both human and environmental health”.

Cooper Lutkenhaus, a 17-year-old high school student from Texas, made history on Sunday by winning gold in the 800m at the world indoor athletics championship. He finished with a time of 1min 44.24sec, 0.14 seconds ahead of Belgium’s Eliott Crestan.Lutkenhaus, who turned 17 in December, broke the previous record for youngest champion held by Ethiopian Mohammed Aman, who was 18 years and 61 days when he won gold in the 800m in 2012.“I came into this knowing I probably wasn’t the favourite, but anytime I step into a final, I believe I have a chance to win,” Lutkenhaus said after his victory. He attributed his win to his youth, saying it gave him the confidence to make a defining move on the third lap.Crestan, who led at the halfway point, praised Lutkenhaus's acceleration, saying he is an incredible talent who could emulate the greats of middle distance running, including David Rudisha.Lutkenhaus's gold was Team USA's fifth of the championships, putting them top of the medal table ahead of Great Britain, who won four.

NASA has initiated the process of returning its massive Space Launch System (SLS) rocket and Orion spacecraft to the launch pad at Kennedy Space Center in Florida. This move comes after completing necessary repairs, setting the stage for a potential launch on April 1.The operation, which can take up to 12 hours, began at 8pm local time. The rocket and spacecraft will be moved 4 miles (6.5km) to launch pad 39B. If all tests are satisfactory, the mission will proceed with a crew of three US astronauts and one Canadian set to fly around the moon.This mission, expected to last about 10 days, marks a significant step towards achieving the goal of returning humans to the lunar surface. The Artemis 2 mission had faced several delays, including issues with helium flow and a liquid hydrogen leak during a previous wet dress rehearsal.The Artemis 2 astronaut crew entered quarantine in Houston as they prepare for liftoff. With the April 1 launch window approaching, NASA remains hopeful that this mission will successfully launch in early April, paving the way for future lunar exploration.

The Kent meningitis outbreak may have reached its peak after only two new cases were reported on Friday. The UK Health and Security Agency (UKHSA) confirmed 18 cases and 11 probable cases, bringing the total to 29.Of the confirmed cases, 13 were meningitis B. The growth in cases may have slowed, but the situation remains serious, with all cases requiring hospital admission. As of 5 pm on Thursday, 2,360 vaccinations had been given and 9,840 doses of antibiotics handed out.Prof Robin May, the chief scientific officer of the UKHSA, said experts are working to understand if the meningitis B bug has become more transmissible. Initial genetic analysis suggests the Bexsero vaccine should provide protection against the type of MenB in this outbreak.The family of a teenager who died from the disease described their immeasurable loss. Juliette Kenny died on March 14, one day after developing symptoms. Her family is now campaigning for teenagers and young people to be routinely given access to the meningitis B vaccination.Experts believe that with an incubation period of up to 10 days, the peak from the initial super-spreading event will have already passed. However, secondary cases among people who did not attend the nightclub but caught it from someone who did are still possible.

The online gaming industry has become a cutthroat world where success is fleeting. Developers are under pressure to create games that generate immediate and significant returns, making it difficult for them to sustain player engagement. Consider the case of Highguard, a free-to-play game that launched with a peak of 100,000 concurrent players on Steam. However, 90% of players abandoned the game within a week, and the developer, Wildlight Entertainment, announced that it would end service on March 12, after fewer than 50 days online. The game's failure can be attributed to several strategic errors, including a refusal to conduct public play tests before release and a complex structure that was difficult for players to understand. However, the main reason for its failure is the increasingly demanding expectations for immediate returns in the live-service game market. Live-service games are investments that are meant to deliver endless revenue, and developers are under pressure to emulate the success of genre juggernauts like Fortnite. However, executives and developers have different priorities, and the online commentariat is often negative about these types of games. Sony, for example, has greenlit several live-service games, but most of them have been canceled before release. One of its few successes is Helldivers 2, which sold 20 million copies and still has a healthy player base. Bungie's new game, Marathon, has also received critical acclaim, but its fate is uncertain due to the high expectations for returns. The game's developers have spent years maintaining Destiny, a trailblazing online shooter, which gives Marathon a significant advantage. However, the pressure to generate profits is still a major challenge, and the game's success is not guaranteed. In conclusion, the online gaming industry is becoming increasingly challenging, and developers are under pressure to create games that generate immediate returns. While some games, like Marathon, show promise, the existential threat facing them is the same: profit margins.

Scientists have made a groundbreaking discovery that could lead to the development of new obesity drugs. By studying the unique metabolic abilities of pythons, researchers have identified a molecule that appears to play a crucial role in regulating appetite and weight loss. The molecule, called pTOS, was found to increase significantly in the blood of pythons after they eat, and when administered to obese mice, it led to a significant reduction in food intake and a 9% loss of body weight over 28 days. The discovery could lead to the development of new obesity drugs that work in a different way to existing medications, such as GLP-1 medications like Wegovy. Unlike these medications, which can have side effects such as nausea and stomach pain, pTOS appears to act on the brain's appetite centers, reducing food intake without these adverse effects. The researchers, led by Dr. Jonathan Long from Stanford University and Prof. Leslie Leinwand from the University of Colorado Boulder, published their findings in the journal Nature Metabolism. They believe that pTOS, which is naturally produced by the snake's gut bacteria and also found in human urine, could be a safe and effective treatment for obesity. While further research is needed before the findings can be applied clinically, the discovery is seen as a promising step towards the development of new obesity treatments. The study's results suggest that pTOS could be a potential therapeutic target for the treatment of obesity and related metabolic disorders.

Graham Napier, a former Essex all-rounder, recalls the 2008 T20 Blast match where he scored 152 not out off 58 balls, breaking the English record for the highest score in T20 cricket. This impressive performance caught the attention of England's selectors and teams from the Indian Premier League (IPL), including Mumbai Indians, who were interested in signing him.Napier, who didn't have an agent at the time, was eventually signed by Mumbai Indians for an undisclosed fee. However, his availability was curtailed by Essex, and he only played one game for Mumbai, scoring 15 runs and taking one wicket. Napier reflects on the experience, stating that he was frustrated by not being allowed to participate in the auction and that the hype surrounding his performance was intense.Tymal Mills, a veteran of franchise T20 leagues, had a more successful auction experience, being picked up by London Spirit for £130,000 in the Hundred auction. Mills had previously been sold to Royal Challengers Bangalore for £1.4m in the 2017 IPL auction. However, he admits that he didn't deliver on his whopping auction fee in 2017, taking only five wickets in five games before injury struck.Mills offers advice to young players, including James Coles, who was signed by London Spirit for £390,000. Mills cautions that the auction process can be bruising and that players must be prepared for the highs and lows of the experience.Napier, now a fire safety officer in Suffolk, has no regrets about his career, stating that he's proud of his achievements and the experiences he had. He notes that loyalty was a significant factor in his career, playing for the same team from age 10 to retirement at 36.
