Introduction of the new technology near airports could interfere with critical airplane instruments such as radio altimeters

US airline chiefs have warned that the introduction of a new 5G service could cause US commerce to “grind to a halt” due to possibly grounding a significant number of aircraft and might “strand tens of thousands of Americans overseas”.

Warnings of an impending “catastrophic” crisis in aviation came in a letter sent to White House National Economic Council director Brian Deese, transportation secretary Pete Buttigieg, Federal Aviation Administration (FAA) administrator Steve Dickson and Federal Communications Commission (FCC) chairwoman Jessica Rosenworcel, Reuters reported Monday.

The shortage of rapid antigen tests for consumers is being exacerbated by state and federal governments and large corporates placing mammoth orders for the kits, causing stock to be diverted from online retailers and pharmacies.

Australia is in the middle of a huge Omicron wave after state and federal governments pivoted from a policy of Covid suppression to one of “living with the virus”, causing a surge in demand for rapid antigen testing kits.

John Griffin, one of the party’s biggest backers, joins growing calls for PM to quit role and seek fresh mandate

One of the Conservatives’ most generous donors has called on Boris Johnson to resign and stand again for the Tory party nomination amid growing calls from its backers for a change of leadership.

John Griffin, the taxi firm tycoon who has given £4m to the Tories since 2013, has become at least the fifth donor to publicly raise concerns over the Downing Street parties scandal.

Tuesday: Big orders from state and federal governments and large corporates for rapid tests are contributing to a shortage. Plus: how to care for Covid face masks

Good morning. Still searching for rapid antigen tests? Orders from big business and governments means less are ending up on the shelves. The extent of the damage in Tonga is becoming clearer. And some tips on how to keep your mask effective.

The shortage of rapid antigen tests for consumers is being exacerbated by state and federal governments and large corporates placing mammoth orders for the self-administered test kits, causing stock to be diverted from online retailers and pharmacies. Australia is currently in the midst of a huge Omicron wave after state and federal governments pivoted from a policy of Covid suppression to one of “living with the virus”, causing a surge in demand for rapid antigen testing kits. The federal health minister, Greg Hunt, denied on Monday the commonwealth was requisitioning supplies of rapid antigen tests, as it can do under the Health Act allows.

• Barcelona midfielder won Ballon d’Or award in 2021
• Chelsea collect three prizes as Hayes and Tuchel triumph

Alexia Putellas followed up her Ballon d’Or triumph by winning the Fifa’s Best women’s player awards for 2021, while Robert Lewandowski beat Lionel Messi to the men’s title on this occasion.

The Barcelona midfielder beat off the challenge of Chelsea’s Sam Kerr and teammate Jennifer Hermoso to win the prize. Meanwhile Lewandowski’s competition came from Mohamed Salah and Messi but the Pole was victorious, retaining the same award he won a year ago.

Humiliation in Australia is a reflection of poor preparation, tactics and team selection. Urgent change is needed at the top

What a way for the Ashes to end. England’s performance with the bat across the series was terrible, with that final-day collapse completely in keeping. I was a bit taken aback by the pitches. It is a tough enough task to face Pat Cummins, Mitchell Starc and Scott Boland on decent surfaces but these were very bowler-friendly, and with the ball moving around at pace, poorly prepared tourists relying on young batters were never likely to excel. It is certainly not fair to look at the lower order in these circumstances, but the final impression was of Ollie Robinson backing away so far that he could hardly reach the ball when it was aimed at the stumps – a fitting denouement to a miserable tour.

Teams get outplayed by better sides, that’s part of sport, but to lose the Ashes inside 12 days indicates something has gone seriously wrong. There were mitigating circumstances in terms of the team’s preparation, which would have been poor even if it hadn’t been affected by bad weather and left Ben Stokes, in particular, coming into the series with hardly any cricket in him. But that’s where the sympathy stops.

Johnson told MPs he did not realise 20 May 2020 event was social gathering but ex-aide says PM was urged not to allow it

Dominic Cummings has accused Boris Johnson of lying after No 10 denied the prime minister was warned against allowing a “bring your own booze” party during the first lockdown.

Johnson admitted to parliament last week that he attended drinks in the Downing Street garden on 20 May 2020 but claimed he had not realised it was a social gathering.

Malik Faisal Akram from Blackburn was killed by police after taking four hostages in a synagogue

A British man who flew to the US, acquired a gun and took hostages at a Texas synagogue had a criminal record and an extensive history of mental health issues, the Guardian understands.

Malik Faisal Akram, a 44-year-old from Blackburn, was killed after a tense 11-hour hostage standoff at the Congregation Beth Israel synagogue in the Dallas suburb of Colleyville on Saturday evening. All four hostages survived the siege and were unharmed.

Gianni Infantino has turned up, which is a relief. Let’s pander to him for while.

He is welcoming everyone to Zurich. Although there are only three people at this ceremony in person.

On the first day of action those still in Melbourne have been giving their views – or refusing to – of the deportation row

He was nowhere and he was everywhere. Etched into the pavement and lingering in the air, each fragile fragment of an atmosphere carrying resentment and relief and quite a bit in between. Melbourne Park is the home of Novak Djokovic’s hubris, the venue at which he won his very first grand slam and has enjoyed the most success of his career to date.

His psyche – that controversial soul of his – is seared into the seats at Rod Laver Arena, where he has lifted nine singles trophies but will not chase a 10th this year. Now it feels he has been cast as Voldemort, the Dark Lord who must not be named – at least by pretty much every player who is not Serbian.

Whales still face many threats, mostly from us, so let us savour this rare congregation of them in the Antarctic Peninsula

Good news doesn’t get any more in-your-face than this. One thousand fin whales, one of the world’s biggest animals, were seen last week swimming in the same seas in which they were driven to near-extinction last century due to whaling. It’s like humans never happened.

This vast assembly was spread over a five-mile-wide area between the South Orkney islands and the Antarctic Peninsula. A single whale is stupendous; imagine 1,000 of them, their misty forest of spouts, as tall as pine trees, the plosive sound of their blows, their hot breath condensing in the icy air. Their sharp dorsal fins and steel-grey bodies slide through the waves like a whale ballet, choreographed at the extreme south of our planet.

Regular exercise may help reduce the pain, inflammation and risk of getting endometriosis, say experts. But here are some things to consider

• In the How to move series, experts offer advice on exercising without exacerbating pain and fatigue

More than 830,000, or around one in nine, Australian women suffer from endometriosis, a condition that can cause debilitating pain during the menstrual cycle as well as during ovulation, sex, urination and bowel movements. Other symptoms include inflammation, bloating, heavy bleeding and fatigue, and it can affect fertility.

The pain and discomfort can lead women to restrict exercise but this can create other chronic health problems, says accredited exercise physiologist Dr Angela Spence from Curtin University. Physical activity can also have myriad benefits.

Face masks are now a fact of life. But even disposable masks require a few simple care steps to stay effective

Every time I leave the house, the refrain – phone, wallet, keys, mask – rattles around my brain while I search my bag for the essentials. Evidence that, despite how strange it felt to wear a mask way back in 2019, when we were worried about bushfire smoke inhalation, face masks have become firmly entrenched in our daily lives.

Masks are proven to reduce the risk of Covid-19 transmission, and help keep us safe at supermarkets and in between our table and the bathroom at restaurants, but they do need to be handled with specific care to remain effective.

Some small businesses could be wiped out without immediate government help due to the Omicron outbreak, industry figures say, with hairdressers reporting up to 60% staff absenteeism.

The chief executive of the Australian Hairdressing Council, Sandy Chong, said seven of the 13 staff at her salon in the New South Wales city of Newcastle had recently tested positive for the virus, swelling sick leave payments at a time when wary clients were staying away.

Surge in mortgages during pandemic suggests house prices will continue to grow for first half of 2022 – at least

Imagine in November 2019 you looked into a crystal ball and foresaw a global pandemic about which we would still be grappling two years later. Would have you then thought it would be a good time to buy or sell a house?

You might have thought economic pandemonium and the shuttering of borders to overseas travellers would signal bad news for the housing market and thus it would be a good time to sell.

A last-minute stage switch meant a huge festival crowd who turned out to see the chart-storming Shark were instead greeted by a little-known indie rocker

• In this Guardian Australia series, our favourite musicians reflect on their most memorable concerts

I had yet to release an album when I was invited to play the Bendigo leg of Groovin the Moo festival in May 2017. Up until point, the biggest shows I had played had been to about 400 people in Melbourne.

Montaigne was on the festival lineup and she was unwell so they shuffled everyone around. Amy Shark – who was riding the wave of Adore and having a real moment – got bumped from the big tent to the main stage and they upgraded me and my band from the fucken car park or something to the big tent.

6 min: Anguissa almost pushes for the right byline but is crowded out. Cape Verde’s defending has been messy but effective so far.

5 min: Cameroon are controlling these opening moments. They have played at a nice tempo, befitting of a host nation, in their games so far. I think Cape Verde, who are no slouches, will be looking to dig in and counter if and when they can.

In his book Reality+ David Chalmers says the material world may lose its allure as VR technology advances

It is hard to imagine humans spending their lives in virtual reality when the experience amounts to waving your arms about in the middle of the lounge with a device the size of a house brick strapped to your face.

But this is where humanity is heading, says the philosopher David Chalmers, who argues for embracing the fate. Advances in technology will deliver virtual worlds that rival and then surpass the physical realm. And with limitless, convincing experiences on tap, the material world may lose its allure, he says.
