Exclusive: Prof Jim Al-Khalili says he will offer solution to ‘arrow of time’ problem in Royal Institution lectures

Tech billionaires attempting to live for ever are, quite literally, wasting their time, a leading physicist has said.

While some normal people are turning to unregulated peptide injections, cold plunges and supplements in an effort to defy ageing, the ultra-rich are aiming for immortality with even more drastic interventions: the tech chief executive Bryan Johnson has even tried injecting plasma from his 17-year-old son – although he later said he saw no benefit from it.

Spend time on the ground and you see how high the stakes are for next month’s contest – for Israelis and Palestinians alike

Candidates always say it, but this time it’s true. When Israel goes to the polls on 27 October, it really will be the most important election in the country’s history – and not just for Israelis. I saw that for myself this last week, in a visit that served as a sharp reminder of both what is at stake – and the role of those watching from afar.

More than one voter I spoke to voiced the fear that, if the coalition headed by Benjamin Netanyahu is returned to power next month, 27 October will not merely be Israel’s most important election: it will be its last. They were not referring to the absence of democracy in the occupied territory of the West Bank – which we’ll come to – but rather to Israel’s internationally recognised, pre-1967 borders: what you might call Israel-proper. There, the last four years have seen a sustained assault on the machinery of liberal democracy by the most rightwing government since Israel’s establishment in 1948 – a committed, focused attempt to remove the checks and restraints on its own power, installing instead a kind of elective dictatorship.

Are you someone who thinks they have all the answers? Is your experience relevant here? Experts on the questions to ask yourself before giving advice

“Often, when people approach you for advice, they just want to talk about how they feel,” says Annalisa Barbieri, advice columnist for the Guardian for almost 20 years. For example, you might vent to a friend about your awful boss, and if they’re shocked it could confirm you’re being treated badly. “I also think people can have a lot of shame when things aren’t working out, and we like to share shame because it’s a hot potato of a feeling.” In other words, not every situation warrants advice. Sometimes, the person just wants to gauge a reaction or to share.

The domestic goddess is about to be let loose in the Bake Off tent. Nigella Lawson and Paul Hollywood spill the beans about bonding over dirty martinis, ‘Professor Precision’ – and why they call themselves the Salty Gang

Like the Cleopatra of cake, new Great British Bake Off judge Nigella Lawson reclines on a chaise longue throughout our interview, gently fanning herself. Fellow judge Paul Hollywood chuckles from a nearby armchair. “She’d sit like this between takes in the tent,” he says indulgently. “Reading a book and sipping a coffee while someone fed her grapes.” “Peeled grapes,” specifies Lawson with a grin.

After Prue Leith stepped down from soggy bottom-spotting duties in January – on the unarguable basis that “I’m 86, for goodness sake!” – there was widespread jubilation when Lawson was announced as her replacement. The arrival of the domestic goddess has created serious buzz around Bake Off’s upcoming series. A contest that was at risk of growing stale has become essential viewing again, thanks to the velvet-voiced, spatula-licking doyenne of culinary TV.

Is an Oxford shirt the ultimate wardrobe staple? Are skin-tight fits ever a good idea? And what’s the perfect fabric for autumn and winter? Our menswear expert has all the answers

• The best white T-shirts for men

The photo above stopped me mid-scroll: Harry Styles, before his 30-show residency at Madison Square Garden, dressed in a big white shirt and smart tailored trousers. After a summer spent parked in front of three fans with ice packs on rotation, when wearing actual clothes felt like punishment, here was proof that normal service had resumed.

So, now the rain’s back and autumn’s creeping in, it’s time to follow Harry’s lead and reintroduce some structure to your wardrobe: coats, knitwear, tailoring, all the pieces that make you look forward to getting dressed in the morning. One staple that’s long overdue a comeback? Shirts.

The Metropolitan police have been granted special powers to tackle violence as the south and east London teams meet again on Saturday after 14 years

Absence has not made the heart grow fonder. Millwall and West Ham meet for the first time in 14 years on Saturday, but it is not going to be a joyous reunion at the Den. The atmosphere will be ferocious and the main hope is that the focus is on the football rather than any nonsense away from the pitch.

These two have plenty of previous, even though they so rarely play each other. The most glaring example is the shocking disorder inside and outside Upton Park when Millwall lost in the second round of the League Cup at West Ham’s old ground in August 2009. A 44-year-old man was stabbed in the chest as trouble raged outside and riot police struggled to maintain order during the game, with play suspended briefly when home supporters invaded the pitch after one West Ham goal.

Exclusive: Official UK security assessment found Microsoft cloud platform storing files was at potential risk from hostile hackers

Vast troves of highly sensitive police data are lying on Microsoft cloud platforms which an official UK security assessment deemed to be vulnerable to “compromise” by foreign actors and the US government, a Guardian investigation can reveal.

The files include criminal records, victim statements, internal emails and sensitive information held by more than 40 police forces across the UK.

Buckingham Palace has refuted claim by Charles Spencer, Diana’s brother, that then prince told him ‘we’ll forget her soon enough’

Earl Spencer has doubled down on his bombshell claim that King Charles said of Diana, Princess of Wales, “rest assured, we’ll forget her soon enough” days after her death, saying he is telling the truth.

The alleged comments, revealed in Charles Spencer’s memoir, Swan Song: Diana, My Sister, which is being serialised in the Daily Mail, prompted Buckingham Palace to issue an extraordinary statement suggesting Diana’s brother had misremembered events, saying “the pain of fraternal grief can cloud reason, affect judgment and colour memory in ways others do not recognise”.

Judge said Nina Power and her friend’s social media posts had ‘the whiff of threat and antisemitism’

Reform UK’s new mega-donor Ben Delo gave a £350,000 loan to a conservative writer fighting a legal case in which a judge later found she had engaged in online bullying and regrettable conduct with a “whiff of threat and antisemitism”.

Nina Power and her friend, the writer Daniel DC Miller, brought the legal action for defamation against the performance artist Luke Turner, who they had accused of falsely calling them antisemitic. At the same time, Turner brought a counter-claim against the pair accusing them of harassment.

Hundreds of cars driven through cones or barriers in England this year, says National Highways

Drivers ignoring roadwork closures to skip queues are putting lives at risk, National Highways has warned, after recording hundreds of incidents this year where cars were deliberately driven through cones or barriers.

The agency, which manages motorways and major roads, said there was increasing concern about incursions into closed-off roadworks and the danger they posed.
