From wood pulp in ice-cream to peat in portobellos, science has transformed how we dine. Do you know exactly what’s lurking in the grub we eat?

Microbial slime and a side helping of sand doesn’t sound like much of a meal, but a startling amount of the food we eat today contains ingredients that are, at the very least, unexpected – and, at worst, dangerous, such as heavy metals from polluted soils.

Then there is the thorny question of what ultra‑processed foods in our diets might be doing to us. “While each food additive, so‑called processing aid, fortificant and unrecognisably modified ingredient has been tested individually and declared safe, are they really?” asks Chris Young, who runs the Real Bread Campaign for Sustain, the alliance for better food and farming, and was named joint winner of Slow Food In The UK’s 2025 person of the year award. “The studies are relatively small and short, leaving history littered with additives that we were once promised would not harm us but were later withdrawn or banned on health grounds. What might the long-term effect be of eating such substances, individually or in the cocktails created for each product and across our shopping baskets?”

Inquiries into who knew what, and when, will be pored over in coming weeks and could ultimately decide Starmer’s fate

When the Guardian revealed that Peter Mandelson had failed his vetting checks before being appointed as British ambassador to Washington, members of Keir Starmer’s cabinet, who were scattered around the world on government business, were caught by the same element of surprise.

In Washington for the spring meeting of the International Monetary Fund, the chancellor, Rachel Reeves, had just come out of a meeting with the Ukrainian finance minister when she was told the breaking news.

It seems that even the Traitors host can’t save the ailing chatshow format. As her series ends, it’s hard not to feel that she never quite got out of Graham Norton’s shadow

Six weeks ago, before Claudia Winkleman launched her BBC One Friday night chatshow, media profiles regularly referenced her “Midas touch” with TV formats. She had left one golden programme, sashaying away from Strictly Come Dancing, but her portfolio still included three other winners: the mega hit The Traitors, its celebrity spin-off for the BBC, and Channel 4’s The Piano.

Half a dozen sofa chats later, Winkleman hasn’t exactly suffered the fate of the mythic King Midas, but The Claudia Winkleman Show can fairly be seen as her least glittering work for several years.

Rising sea levels and ecological damage caused by heavy use of flood defence system force city authorities to consider next move

The Arsenale, the colossal shipyard that was the engine of the Venetian Republic’s domination for seven centuries, remains the nucleus of the city’s control over the water. Its northern section is made up of cavernous brick warehouses called capannoni, which in the 16th century could produce a warship a day through a rigorously ordered assembly line.

Now, one of them houses the operations centre of the Mose, the sprawling flood defence system that protects the city.

Suspicious wagers on the US-Israel war in Iran are creating huge windfalls and raising concerns among lawmakers

Sixteen bets made $100,000 accurately predicting the timing of the US airstrikes against Iran on 27 February. Later, a single user would make over $550,000 after betting that Ayatollah Ali Khamenei would topple, just moments before his assassination by Israeli forces. On 7 April, right before Donald Trump announced a temporary ceasefire with Iran, traders bet $950m that oil prices would come down. They did.

These bets and other well-timed wagers accurately predicted the precise timing of major developments in the US-Israel war with Iran, creating huge windfalls and raising concerns among lawmakers and experts over potential insider trading.

A group of 50 survivors of alleged sexual abuse by Harrods’ former owner Mohamed Al Fayed are calling for “meaningful consequences” for those who they claim facilitated and ignored the abuse.
