A great piece to read before this game begins:

Here is how Arsenal booked their spot in the quarter-finals, where they will play Chelsea:

Around the world, global heating is already causing more frequent heatwaves that last longer and bring more heat. Guardian Australia's Graham Readfearn has put his body to the test in an experiment see what effects the heatwaves of the future will have on humans. At the University of Sydney, he steps into a climate chamber that simulates the increased temperatures and humidity predicted in a rapidly warming climate. 'The sweat is stinging my eyes,' he says. 'It's 43C and the air is sticky and humid. It's getting hard to breath.'

Crystal Palace’s Conference League hopes hang in the balance after a 1-1 draw against Bosnia and Herzegovina’s Zrinjski Mostar in the first leg of their knockout phase playoff.

Oliver Glasner had reinforced his attacking ranks since their last European outing in December, but it was Ismaïla Sarr, assisted by the January signing Jørgen Strand Larsen, who broke the deadlock on the stroke of half-time.

For Nottingham Forest, and particularly Vítor Pereira and the 1,200 supporters who signed up to this trip to Istanbul, an evening they will not forget in a hurry. Pereira’s first match in charge could scarcely have been more impressive than the statement victory Forest recorded at Fenerbahce to put themselves in a commanding position to reach the Europa League last 16. By the end the yellow and navy stronghold had emptied and the Forest fans present savoured every moment. First they sang: “Can we play you every week?” Then a chorus of: “Where’s your famous atmosphere?”

Evangelos Marinakis’s grand aim at the outset of this season, before moving on to his fourth manager since August, was to win this competition across the Bosphorus in Besiktas in May and, for all of the chaos and valid criticism, on this evidence it is very much an achievable aim. Forest are in a position of power before Fenerbahce visit for the second leg next Thursday.

Second carrier strike group heads for region as US waits for Iran to respond after talks in Geneva

Donald Trump has said it will be clear within “probably 10 days” whether he can reach a nuclear deal with Iran, as the US military buildup in the Middle East intensifies with the impending arrival of a second carrier strike group.

The US president, speaking at the inaugural meeting of his Board of Peace in Washington DC, insisted Iran could not have a nuclear weapon and emphasised that “bad things will happen” if the country continued “to threaten regional stability”.

Freedom.gov appears to be administered by a branch of the Department of Homeland Security

The US has built a portal that will allow Europeans to view blocked content including alleged hate speech and terrorism, according to Reuters.

The portal, “freedom.gov”, will allow worldwide users to circumvent government controls on their content. The site features a graphic of a ghostly horse galloping above the Earth, and the motto: “Information is power. Reclaim your human right to free expression. Get ready.”

The police investigation into the king’s brother forces Britain to confront whether privilege can coexist with democratic scrutiny and the rule of law

The arrest of Andrew Mountbatten-Windsor the king’s brother, should be the moment deference ends and accountability begins – a correction long overdue. For more than 15 years, allegations surrounding Mr Mountbatten-Windsor were managed away by silence, an out-of-court settlement and his withdrawal from royal duties. In short, his behaviour was viewed as an image problem to be handled privately. That era now looks to be over.

That the eighth in line to the throne was sitting in a police cell on his 66th birthday shows how far he has fallen. The formal investigation means that the question is no longer about protecting the monarchy but one of what happened, and who might be responsible for unlawful acts. Mr Mountbatten-Windsor’s descent into ignominy has unfolded slowly but inexorably. His stupidity and arrogance led him to believe that he could talk his way out of his relationship with the convicted child sex offender Jeffrey Epstein. Instead, he faces a legal and constitutional reckoning.

The deregulation agenda being pushed by Germany’s chancellor and Italy’s prime minister is economically and ethically flawed

When the European Union launched its green deal in 2019, putting into law the goal of climate neutrality by the middle of the century, it showed strategic foresight as well as global leadership. Russia’s war in Ukraine has starkly underlined the extent to which the continent’s energy security – and its future prosperity – is dependent on the transition away from fossil fuels. Lately, however, EU leaders’ environmental approach appears to be echoing the youthful St Augustine’s plea on chastity: make us greener, but not yet.

The recent European Industry Summit in Antwerp made unusually big headlines thanks to Sir Jim Ratcliffe’s xenophobic outburst over immigration. But it was also notable for fierce attacks on one of the most important pillars of EU environmental policy. The bloc’s emissions trading system (ETS) – which makes polluters pay for the C02 they emit – has achieved dramatic results in driving down overall emissions since 2005 and encouraging green innovation. Worryingly, the German chancellor, Friedrich Merz, appeared to sympathise with demands from Sir Jim and other CEOs for a radical relaxation of the rules.

Sydney’s Qing Fong dance troupe undergoes intensive training for their busiest period of the year when they will perform more than 100 times and earn ‘lots of pats’ from the crowd

Drums and cymbals echo across Mingyue Lay temple’s sun-baked concrete car park. Lion heads made out of papier-mache are dotted around the lot and pairs of kids are jumping on to poles, tables or each other’s shoulders – all while connected at the hip.

It’s a sticky night in Sydney’s west, but the 33C heat doesn’t faze these lion dancers, who are gearing up for their busiest period: lunar new year. The festivities continue well past the day itself, with more than 100 performances across three weeks. On the eve of lunar new year, the studio will start their performance at the temple in Bonnyrigg at 9pm and finish well past midnight.

Research adds weight to theory Arrokoth’s two lobes produced by gravitational collapse – and reveals process

It is the most distant and primitive object ever visited by a spacecraft from Earth: now researchers say they have fresh insights into how the ultra-red, 4bn-year-old body known as Arrokoth came to have its distinctive snowman-like shape.

Arrokoth sits in the Kuiper belt, a vast, thick ring of icy objects that lies beyond the orbit of Neptune. This region of space is home to most of the known dwarf planets as well as comets and small, solid rubble heaps called planetesimals – the building blocks of planets.

Political tensions rise after fatal attack at protest in Lyon as Emmanuel Macron hits out over remarks by Italian PM

A French prosecutor is seeking murder charges against seven suspects in the fatal beating of a far-right activist that has fuelled political anger beyond France’s borders, prompting Emmanuel Macron to tell Italy’s Giorgia Meloni to keep out of French affairs.

Quentin Deranque, 23, died from head injuries after being attacked by at least six people on the sidelines of a far-right protest in Lyon on 12 February. Most of the 11 suspects who have been detained are from far-left movements.

I was at Dyche’s final game in charge and Omari Hutchinson was underwhelming, to say the least. It will be interesting to see how he reacts to the new regime.

Pereira: “Today is three days working. but working to play in a way to try short communications, be very clear. Today I hope that I see my team play organised with tactical organisation, and be able to express themselves, play with courage and a mentality to win.”

USA 0-0 Canada, first period, 15:13 left: Poulin with the shot. Remember that she was out injured when these teams played earlier in these Games. The USA won’t want to let her have many touches.

USA 0-0 Canada, first period, 15:57 left: To underscore the point, NBC commentator AJ Mleczko, fresh from calling part of yesterday’s men’s game with Snoop Dogg, recalls a year in which her US team lost once – in the Olympic final.

• Nikita Filippov wins silver as neutral in sport’s debut

• Switzerland’s Marianne Fatton wins women’s sprint

We can partly thank Sir Arthur Conan Doyle for popularising the Winter Olympics’ newest sport, which made its debut amid an unrelenting snowstorm, a touch of mayhem and no little controversy in Bormio.

In 1894, the year after he had killed off Sherlock Holmes at the Reichenbach Falls, Conan Doyle wrote about his own perilous 15-mile journey across the 8,000-feet high Maienfelder Furka Pass one that involved skiing and mountaineering.

Report details harrowing 18-month occupation of North Darfur capital, showing destruction aimed at ethnic communities

The siege and capture of the Sudanese city of El Fasher by the paramilitary Rapid Support Forces group last October bore “the hallmarks of genocide”, a UN-mandated fact-finding mission has said.

In a report detailing the harrowing 18-month occupation of the capital of North Darfur, investigators concluded that the RSF and allied militias deliberately inflicted conditions calculated to bring about the physical destruction of the Zaghawa and Fur ethnic communities.

• ‘When you see a player upset, normally it’s for a reason’

• Head coach reacts to Vinícius Júnior’s racism claims

Liam Rosenior has called for players and coaches found guilty of racism to be banned from football for life and said experiencing abuse on a football pitch “is the worst feeling you can ever possibly imagine”.

The Real Madrid forward Vinícius Júnior left the pitch after alleging that Benfica’s Gianluca Prestianni racially abused him during their Champions League match on Tuesday. Prestianni has denied racist abuse and Benfica have said he was a “victim” of a “smear campaign”. The Argentinian faces a 10-game ban if found guilty by Uefa.

Young Glasgow artist Trackie McLeod talks us through Utopia, the boozer he built from scratch where punters can sink a beer, throw darts at Thatcher or Trump – and win chocolate coins from one-armed bandits

‘The art world has a real issue with making things overly conceptual, too complicated and using wanky jargon,” says Trackie McLeod. “It alienates people.” So, for his latest show, Utopia, the 32-year-old Glaswegian has decided to create something more welcoming and familiar: a pub.

Custom-built from scratch, the exhibition is a fully functioning boozer. McLeod will pull pints for punters, there’s a dartboard where you can take aim at images of Thatcher or Trump, and visitors can explore his mixed-media artworks, spanning print, sculpture and sound, and swing by to catch drag acts, DJs and panel discussions.

Making choices can be difficult when options are not clearly better or worse than each other – how does one even begin to decide?

I love cats. I’d been idly keeping an eye out for a less allergenic breed, when bam – a kitten became available. Suddenly I had to decide whether to take the leap.

Even though I’d been considering cat ownership for a while, I felt anxious. I mulled over all the responsibilities: vet bills, stubborn allergies, years of commitment. One big sticking point was travel. Having a cat would be rewarding, but did I want it right now if it meant I couldn’t decide on a whim to book a cheap last minute flight to another city? Did I want to buy Fancy Feast, or stay fancy-free?

Andrew Mountbatten-Windsor has been arrested on suspicion of misconduct in public office by police investigating his dealings with Jeffrey Epstein. Six unmarked police cars and plainclothes officers arrived at the Sandringham estate while the former prince was celebrating his 66th birthday. Officers searched the Norfolk property as well as Mountbatten-Windsor's former home in the Royal Lodge in Great Windsor Park. Lucy Hough speaks to the Guardian journalist David Pegg

Exit of Devyani Saltzman, described as Barbican’s ‘driving force’, announced a few weeks after arrival of new CEO

• Italian government urges IPC to reconsider its stance

• Russian and Belarusian athletes to compete under flags

Italy, the Winter Olympic hosts, has called for a reversal of the decision to let 10 Russian and Belarusian athletes compete with national flags and anthems at next month’s Paralympic Games.

The foreign minister Antonio Tajani and sports minister Andrea Abodi urged the International Paralympic Committee to reconsider its stance due to Russia’s four-year-old invasion of Ukraine, saying it contradicted the Olympic spirit.
