Israel has made it through to the final of the Eurovision song contest, setting the stage for a tense and politically charged event in Malmö on Saturday.

At Thursday’s second semi-final in Sweden’s third largest city, viewers from the competing countries backed the Israeli singer Eden Golan as one of the 10 entries to progress.

Earlier in the day a demonstration in Malmö’s city centre saw thousands protest against the decision to include Israel while its military campaign in Gaza continues. Further protests, and an alternative concert billed by organisers as a “a song contest without genocide”, are planned for Saturday.

Twenty-six of the 37 entrants will compete in Saturday’s final. After Loreen’s triumph last year, the host and record winner Sweden was guaranteed a place alongside the “big five” of France, Germany, Italy, Spain and the UK, which make the biggest financial contributions. The remaining 20 qualified via the semi-finals on Tuesday and Thursday.

Israel was allowed to compete this year after it agreed to modify the lyrics of its entry, a ballad widely understood to be a reference the Hamas massacre on 7 October.

The original version of Hurricane, which was titled October Rain, was barred by the European Broadcasting Union (EBU) for breaking rules on political neutrality.

Eurovision’s 68th edition takes place seven months into Israel’s bombardment campaign on the Gaza Strip, and just days after the Israel Defense Forces launched a major military offensive in Rafah, Gaza’s southernmost city.

Golan, 20, who was born in Israel to Russian parents, was booed by members of the audience during dress rehearsals on Wednesday. Israel’s prime minister, Benjamin Netanyahu, later released a statement in which he praised the singer for “successfully facing a wave of antisemitism while standing and representing the state of Israel with respect”.

Earlier on Thursday, between 5,000 and 6,000 protesters had marched through Malmö city centre to protest against Israel’s military campaign in Gaza and the country’s inclusion in the event, according to police.

A rally in support of Israel’s inclusion in the contest, held in Malmö’s Hästhagen neighbourhood, drew about 120 people, police in attendance said.

Among the crowd of protesters waving Palestinian flags on Malmö’s town square was Greta Thunberg. “It is outrageous that Israel is allowed to participate”, said the environmental activist, wearing a black-and-white checkered keffiyeh over her shoulders. “We cannot remain silent during a genocide.”

Pro-Palestinian protesters have accused the EBU of double standards. It disqualified Russia from Eurovision in 2022, saying the country’s inclusion would “bring the competition into disrepute”.

The EBU has defended its decision to allow Israel to compete, saying Eurovision is “a non-political music event” and “not a contest between governments.”

Palestinian flags have been banned inside the venue, but at Tuesday’s semi-final one performer wore a keffiyeh around his wrist.

Eric Saade, whose father is a Palestinian from Lebanon, wore the garment while performing his 2011 Eurovision entry Popular. The EBU later said he had compromised “the non-political nature of the event”.

“The EBU seems to think my ethnicity is controversial,” Saade said in a post on Instagram. “It says nothing about me, but everything about them.”

Ireland’s entry, Bambie Thug, was told to remove makeup from their face and legs that spelled out “ceasefire” and “freedom for Palestine” in a medieval Celtic script, according to the Irish Times.

A judge found Thursday that Beach Boys founder and music luminary Brian Wilson should be in a court conservatorship to manage his personal and medical decisions because of what his doctor calls a “major neurocognitive disorder”.

At a hearing, Los Angeles superior court judge Gus T May approved the petition filed by the 81-year-old Wilson’s family and inner circle after the death of his wife in January, Melinda Ledbetter Wilson, who handled most of his tasks and affairs.

“I find from clear and convincing evidence that a conservatorship of the person is necessary,” May said at the brief hearing. The judge said that evidence shows that Wilson consents to the arrangement and lacks the capacity to make healthcare decisions.

May appointed two longtime Wilson representatives, publicist Jean Sievers and manager LeeAnn Hard, as his conservators. There were no significant objections raised.

Two of Wilson’s seven children, Carnie and Wendy Wilson from the singing group Wilson Phillips, asked through their attorney that all the children be added to a group text chain about their father and that all be consulted on medical decisions. The judge granted the stipulations.

A doctor’s declaration filed with the petition in February said Wilson has a “major neurocognitive disorder”, is taking medication for dementia and “is unable to properly provide for his own personal needs for physical health, food, clothing, or shelter”.

Sievers and Hard have had a close relationship with Wilson and his wife for many years. In a report, Robert Frank Cipriano, an attorney appointed by the court to represent Wilson’s interests, said Wilson acknowledged the need for the conservatorship and said he trusts the judgment of the two women.

Cipriano’s report to the court said he visited Wilson at his “impeccably well maintained residence in Beverly Hills”, where he lives with two daughters and a longterm live-in caregiver.

Wilson can move around with help from a walker and the caregiver, Cipriano said, and he has a good sense of who he is, where he is and when it is, but could not name his children beyond the two that live with him. He said Wilson was “mostly difficult to understand and gave very short responses to questions and comments”.

Wilson, his seven children, his caregiver and his doctors consulted before the petition was filed, according to a family statement at the time. It said the decision was to ensure “there will be no extreme changes” and that “Brian will be able to enjoy all of his family and friends and continue to work on current projects”.

Judges in California can appoint a conservator for a person, their finances – referred to as the estate – or both, as was the case with Britney Spears. Spears’ case brought attention – much of it negative – to conservatorships, known in some states as guardianships, and prompted legislative changes. Wilson’s case is closer to the typical traditional use of a conservatorship, which very often is installed for an older person in irreversible mental decline.

The Wilson petition did not seek a conservator of the estate because his assets are in a trust, with Hard as a trustee.

Deeply revered and acclaimed as a co-founder, producer, arranger and chief songwriter of the Beach Boys and a masterful innovator of vocal harmony, Wilson struggled with mental health and substance abuse issues that upended his career in the 1960s.

He was inducted into the Rock and Roll Hall of Fame in 1988 along with his bandmates, including his brothers Carl and Dennis and his cousin Mike Love.

Neuralink’s first attempt at implanting its chip in a human being’s skull hit an unexpected setback after the device began to detach from the patient’s brain, the company revealed on Wednesday.

The patient, Noland Arbaugh, underwent surgery in February to attach a Neuralink chip to his brain, but the device’s functionality began to decrease within the month after his implant. Some of the device’s threads, which connect the miniature computer to the brain, had begun to retract. Neuralink did not disclose why the device partly retracted from Arbaugh’s brain, but stated in a blogpost that its engineers had refined the implant and restored functionality.

The decreased capabilities did not appear to endanger Arbaugh, and he could still use the implant to play a game of chess on a computer using his thoughts, according to the Wall Street Journal, which first broke the news of the issue with the chip. The possibility of removing the implant was considered after the detachment came to light, the Journal reported.

Arbaugh’s implant began running into problems in late February, according to Neuralink’s blogpost, when an undisclosed number of the chip’s threads “retracted from the brain, resulting in a net decrease in the number of effective electrodes”. This decreased the device’s bits per second, which is essentially a gauge of how well the implant could perform its tasks.

Neuralink, which Elon Musk owns and which was valued at about $5bn last year, has widely touted the success of its first implant, positioning itself as a world leader in brain-chip technology. Although the device is still in its early stages, the company’s disclosure brings more attention to the untested and complicated nature of the experimental procedure.

Neuralink’s implants function by embedding a small container in the skull that houses a processing chip and battery, along with 64 fine threads that connect with the brain tissue and interact with the neural signals it sends out. Arbaugh, who is quadriplegic, can control computer devices like a keyboard or mouse cursor with his implant.

Arbaugh praised the implant during a demonstration in March and said that it had “already changed his life”, while also stating that it had not been perfect and they “have run into some issues”.

Before Neuralink conducted its first human implant, it extensively experimented for years on animals including sheep, pigs and monkeys. Regulators have launched several investigations into the company’s practices at those animal testing labs, earlier this year saying that they found quality control and recordkeeping problems at one California research facility.

One night, I was preparing steak for dinner and mistakenly reached for the wrong white granulated substance. Instead of salting my steak to create a brown crust by searing, I created a brown crust with notes of caramel.

Ethan Frisch, co-founder of Burlap & Barrel, an artisanal spice company that works with small producers worldwide, laughed wryly when he heard this story over Zoom. “This is the first time in history anyone could make that mistake. Refined, white-bleached sugar is a very modern development in the centuries-old sugar industry. Sugar is brown! It’s only white when you do a lot of work to remove the brownness.”

His co-founder, Ori Zohar, elaborated: “The whole sugar industry is focused on this pure white chemical that is so far away from being a plant: a shelf-stable, consistent, interchangeable ingredient. None of those qualities make for good food,” though it makes an item that can be traded around the world for similar base prices.

Many of us only know white, granulated sugar that comes packaged with no information about its sugarcane or beet origins – much less its geographical origins – on its package. But sugar is diverse. White, processed sugar makes up the largest segment of the global market, but sugar also comes in liquid and brown forms. About 80% of the world’s production comes from sugarcane, but some comes from beets. Even sugarcane itself is not a monolith; though most sugar is derived from the Saccharum officinarum species and its hybrids, there are hundreds of varieties which have adapted (or been adapted through human intervention) to their specific ecosystems.

Zohar and Frisch are on a mission to “do to sugar what has been done to salt” in the last few years. You can now buy specialty salts from specific places and have specific characteristics: a black Himalayan salt that has a sulphurous funk or Burlap and Barrel’s Pearl salt from Tanzania’s Swahili coast, with its surprisingly spherical crystals.

Saltverk, which sells hand-harvested salt from Iceland, has been riding this wave. Founder Björn Steinar Jónsson said, “People want to know where the products they’re buying are from. We’ve seen this as a gradual growth in the salt industry, and really, we’re only at the beginning stages of where people understand what’s going into their salts. As a staple ingredient used by most of the world, sugar could follow a similar path.”

This is not just marketing. A sugar’s texture and taste can be as individual as coffee beans from a corner of Ethiopia or wine grapes grown on a chilly slope in the Pacific north-west.

Brown sugar from Okinawa in Japan is a favorite of pastry chef Salvatore Martone of Le Jardinier in New York. He said: “Okinawa brown sugar (kokuto) is produced on eight remote Japanese islands. Each island produces sugar that has a slightly different taste. The sugar is sold in small irregular lumps, and the flavor is rich minerally smokiness with an earthy undertone and a hint of bitterness.” He uses it for ice-cream.

Burlap & Barrel’s founders want to introduce consumers to sugars connected to a specific place and that have a distinctive flavor born of the environment that produced them. The company’s work expands the market for traceable sugar, focusing on sourcing from communities using traditional processing methods.

It’s introduced panela, a traditionally unrefined cane sugar from Boyacá, Colombia. In June, the company is launching two other single-origin sugars, jaggery from Satara district, India, and a granulated sugar from Portvale, Barbados. When the company uses the term “single-origin”, it doesn’t merely refer to a country of origin, but a single farm or producer.

Had I reached for their sand-textured panela in making my steak, I could not have mistaken it for salt. Its soft, irregular granules are the color of milk caramel, with which it shares similar aromas. A spoonful is like sucking on sweet cinnamon toffee. It melts on the tongue, leaving a trace of floral spice, as if I took a shot of ginger juice.

The jaggery has the varied, irregular texture and look of crushed peanuts, and opening it fills my apartment with the scent of fresh squeezed sugarcane. It comes from Dr Shashikant Salunkhe, who has grown turmeric for Burlap & Barrel as part of a regenerative agricultural system. A local refiner filters the raw sugarcane juice with wild okra, whose gel collects any floating impurities. The jaggery is granulated and then stone ground, ancient methods that are worlds away from industrial filtration and mechanized refinement.

The Barbadian sugar’s crystals are startlingly angular and crunch loudly between one’s teeth.

“Barbadian sugar has to de-commoditize if they’re going to compete globally,” said Frisch. This means that the country’s producers need to embrace their sugar as a specialty product and divert it from being blended with other sugars before it reaches supermarket shelves where it will be simply labeled “cane sugar”. Frisch wants people to understand what makes Barbadian sugar so good – the terroir of its coral island, flavors enhanced by molasses, cane fed by rainwater and not irrigation like in most industrial practices, and its history.

Sugar production has an ugly past. About 5 million slaves were brought to the Caribbean, most to toil on sugar plantations starting in the mid-1500s. The slave trade reached its height in the 1700s, and Barbados, known as Sugar Island, was its crown jewel. Abolitionists in Europe and the US waged boycotts of sugar, a slave-derived good that represented abhorrent working conditions.

Centuries later, Frisch and Zohar want consumers to demand sugars that retain their individual, nuanced flavors. “Home cooks and chefs have huge buying power,” said Zohar, which could advance more sustainable and equitable production. Sugarcane farms are responsible for massive deforestation. Added to innumerable food products, sugar drives the global obesity epidemic. Sugar from the Dominican Republic’s Central Romana corporation, which is often supplied to and sold as Domino brand, has been banned from the US since November 2023 due to allegations about exploitative work conditions and forced labor among its largely Haitian migrant workforce.

But as of the moment, it’s difficult to know exactly where your sugar comes from. Non-alcoholic beverage company Everleaf goes to extraordinary lengths to source botanicals. Founder Paul Mathew is a conservation biologist, and his company has tracked down “cherry blossoms, hand-picked in the Shizuoka region of Japan between May and August” and gum acacia, used for mouthfeel, from the Sahel region of Africa.

That wasn’t possible with sugar, which Mathew said is all being “hoovered up into a commodity-based industrial system”. The UK-based company is currently switching from fair-trade sugar derived from sugarcane to beet sugar from the UK, prioritizing a lesser carbon footprint.

One way for a company to know where its sugar comes from is for that business to grow it themself. This is what Copalli Rum in Belize chooses to do. The majority of rum is made from molasses, produced when sugarcane juice is boiled multiple times in sugar’s refining process and sucrose is removed. But new agricole-style rums, which are made from fermenting fresh sugarcane juice, like Copalli, are emerging from former commodity sugar plantation fields, from Hawaii to Belize. Copalli uses red and black cane instead of yellow cane engineered over many years to produce commercial sugar in Belize.

Wil Maheia, the philanthropy services advisor for Copalli, has tended to this area his entire life. His great-grandparents worked the land when it was a sugarcane plantation and he helped organize Belize’s first debt-for-nature swap (a transaction where a country’s debt is exchanged for environmental conservation commitments).

He’s proud to say: “We have never cut any rainforest to plant cane.” To the contrary – Copalli is cultivating 220 acres of sugarcane on old citrus orchards rather than reaching into 12,000 acres of rainforest. As the largest employer in southern Belize, it’s creating jobs that do not rely on the logging industry and deforestation.

British farmers are considering walking away from their farms as the recent record run of wet weather has left the sector “on the brink”, rural bodies have warned.

The Agriculture and Horticulture Development Board (AHDB) and the Soil Association raised concerns over the perilous situations facing many in their industry, with profits being squeezed and extreme weather driven by the climate crisis putting financial and mental strain on farm owners.

Helen Browning, the chief executive of the Soil Association, said: “A lot of farmers are really considering their options, and thinking about walking away from their farms, as they could make far more money doing something else.”

Browning, who runs a livestock and arable farm in Wiltshire, added: “If you were economically rational, you wouldn’t farm.”

The trade bodies’ comments came during a briefing on Thursday run by the Energy and Climate Intelligence Unit (ECIU) thinktank ahead of the second annual Farm to Fork summit being hosted by Rishi Sunak at No 10 next week.

The summit is expected to discuss the UK’s future food security against the backdrop of extreme wet weather that has affected four in five farms in the past 12 months.

The UK has been hit by 11 named storms since September, and experienced the wettest 18-month period since records began in 1836.

Tom Clarke, a board member at the AHDB, said the biggest effect on farms this year had been the poor weather, with many farms planting fewer crops, or no crops at all, due to fields being flooded. “It’s been a hell of a year, I think farmers across the UK are really on the brink, not only mentally, but financially and ecologically as well.”

Clarke, who farms wheat, sugar and other combinable crops in Cambridge, said the rain meant some of his fields had no crops for the first time in decades, while a large percentage of those planted were in bad condition.

The AHDB’s arable crop report for April showed that only 45% of winter wheat was rated as being in good or excellent condition in the month, well below the 88% in the same period last year.

Clarke also pointed to the phasing out of EU basic payment scheme subsidies as another challenge faced by farmers. The payments were supposed to be replaced by the UK government’s sustainable farming incentive subsidies, but the rollout of these has been delayed.

“This means that there is less money in the system for farmers, that affects the viability of farming economics in this country,” he said.

Last week, the National Farmers’ Union annual survey revealed that farmers’ confidence had hit its lowest level in at least 14 years, with 16% of respondents saying their farms were not profitable and may not survive – the highest percentage ever recorded.

Thursday’s ECIU briefing also heard from the Food Foundation charity, which warned that the climate crisis in the UK and overseas was leading to price volatility and many British households were unable to cope with soaring costs.

Anna Taylor, the charity’s executive director, said: “Inflation may be out of the news but a basic food basket remains 25% higher than it was two years ago and wages have not kept pace.

“The result is 8 million adults and 3 million children living in food insecurity and struggling to put food on the table.”

What is the most effective action individuals can take?

Most experts (76%) backed voting for politicians who pledge strong climate measures, where fair elections take place. The recommendation is powerful in a year when voters in countries including the US, UK, India, the EU, Mexico and South Africa and more all go to the polls.

“I feel the reason behind the lack of response to date is the nervousness of politicians,” said Prof Bill Collins, at the University of Reading in the UK. “Polls suggest voters are actually more willing for governments to take stronger climate action.” Another expert highlighted the danger of a second Donald Trump presidency to climate action.

The survey sought the view of every contactable lead author and review editor of reports by the Intergovernmental Panel on Climate Change since 2018, with 380 of 843 responding. Overall the scientists were extremely pessimistic about the prospects of holding global temperature rises below internationally agreed targets.

“The science is there, but the lack of will of politicians worldwide is retarding climate change [action],” said Prof Alexander Milner, at the University of Birmingham in the UK.

What about reducing flying?

The second choice for most effective individual action, according to the experts, was reducing flying and fossil-fuel powered transport in favour of electric and public transport. This was backed by 56%, and two-thirds said they had cut their own number of flights.

Flying is the most polluting activity an individual can undertake and makes up a large part of the carbon footprint of the rich. Globally it is a small minority of people who drive aviation emissions, with only about one in 10 flying at all. Frequent-flying “super emitters” who represent just 1% of the world’s population cause half of aviation’s carbon emissions, with US air passengers having by far the biggest carbon footprint among rich countries.

Can eating less meat help?

Meat production has a huge impact on the environment. Most people in wealthy countries already eat more meat than is healthy for them and more than 60% of the scientists said they had cut their own meat consumption. Almost 30% of the experts said eating less meat was the most effective climate action, while a similar proportion backed cutting emissions from heating or cooling homes, by installing heat pumps, for example.

Is protesting an effective form of climate action?

Almost a quarter of the scientists said they had participated in climate protests, as citizens who are deeply worried about global heating. This included scientists from every continent, including those from the US, Argentina, Germany, Bangladesh, Kenya and Australia.

What else?

Having fewer children was backed by 12% of the experts but many made further suggestions. Everyone should “talk about climate as the leading existential threat to societal stability”, said one. Shifting savings or pension funds away from fossil fuel investments and towards green ones was also mentioned by multiple experts.

Prof Vanesa Castán Broto, at the University of Sheffield in the UK, suggested a blunt action for one particular group: “Stop working for the fossil fuel industry.” And a scientist from Cameroon advocated avoiding products responsible for deforestation, such as some beef, timber and cocoa.

Can individual action really help?

Many of the experts were clear on the limits. “It can only go so far. Deep, rapid cuts in carbon emissions from oil and gas, as well as other sectors such as transport, are needed, which are outside the control of the average individual,” said Dr Shobha Maharaj, a climate impacts scientist from Trinidad and Tobago.

“Individual action can only amount to a drop in the bucket – only systemic changes will be sufficient,” said Prof David Wrathall, at Oregon State University in the US. But Prof Hiroyuki Enomoto, at Japan’s National Institute of Polar Research, said that while individual actions have a small impact, they are important in increasing collective awareness of the problem.

Are the scientists walking the talk themselves?

Yes. Many foresee catastrophic levels of global heating and are shifting their focus away from the physics of the climate system towards action that slows global heating and work that protects people against the climate impacts they now see as unstoppable.

“I work more on projects with vulnerable communities so they improve their adaptation to climate change, whose impacts we already experience and which will increase in the future,” said Prof Carolina Vera at the University of Buenos Aires in Argentina.

Numerous scientists said they had given their time as expert witnesses in legal cases on climate change and others said they were helping groups to develop new climate policies.

Maharaj now chooses to spend at least half her time turning science into action, as the science director of a company implementing responsible reforestation. “There are so many people on the ground who care and who want to make a difference; that is truly encouraging and really drives me,” she said.

A cruise ship has journeyed into New York City’s harbor bearing a gruesome cargo in the form of a huge, dead whale sprawled across its bow.

The incident happened on Saturday, according to local US media reports, and the event is being held by some as further evidence of the unfortunate impact on sea life that large vessels can have.

The 44ft-long whale corpse was an endangered sei whale and was caught on the ship’s bow when it arrived at the Port of Brooklyn, according to a National Oceanic and Atmospheric Administration fisheries spokesperson, Andrea Gomez.

The boat involved was the Meraviglia, which docked in New York before sailing on a journey to ports in New England and Canada. It is owned by Geneva-based MSC Cruises.

“We immediately notified the relevant authorities, who are now conducting an examination of the whale,” officials with the cruise line said in a statement, who added that the company had regulations in place to avoid collisions with whales and other animals at sea.

“We are deeply saddened by the loss of any marine life,” the statement said.

The whale is now the subject of a necropsy to try and determine how it died, notably if it was already dead when hit by the cruise ship. Sei whales are one of the largest whales and are a protected species.

To say the images of Andreas Heide during his working day are dramatic is an understatement: a freediver deep underwater in a black wetsuit, his lean silhouette enhanced by powerful bladed fins, looking up towards a group of orcas; or standing on an ice sheet next to a small sailboat in the Arctic, amid a sea full of dangerous looking ice floes in poor visibility.

But for the marine biologist and adventurer, plunging into freezing waters with orcas or embarking on a 4,500-mile sailing expedition from the Arctic north to the UK and back, documenting whale behaviour and their dramatic encounters with polar bears, whales and walruses, is all part and parcel of storytelling that he hopes can ultimately change human behaviour. He works with scientists and conservationists, photographers and drone pilots, to underline the importance of conservation in the extreme north, under challenging conditions.

“There is a question we all ask ourselves, as environmentalists and journalists, which is, why, when as humans we are aware of climate change and plastic pollution, do we fail to act collectively to do something about it?” says Heide. “Part of that reason is a lack of knowledge.

“Imagine a photo of the moon from the moon’s surface. But then, imagine the moon’s surface with an astronaut on it, it’s completely different. It has an emotional response. That’s what we want to convey.”

Heide, 45, is one of eight people to be nominated for the Shackleton medal for the protection of the polar regions, which recognises individuals putting everything on the line to protect the Arctic and the Antarctic. The winner of the award, judged by the explorer Sir Ranulph Fiennes and the historian and presenter Dan Snow, among others, will be announced on 10 May.

Born in the Norwegian coastal town of Stavanger, Heide spent his childhood close to the water. He began freediving at the age of 10, and had his first boat at eight or nine. He spent two years in the military as a parachutist, working with helicopters and submarines, to build up the skills needed to navigate the Arctic.

He says he wants to share knowledge and create an emotional connection with the marine environment. “To make people understand what they do matters for the Arctic ecosystem, including the polar bears and the blue whales and the orcas.”

He works with whales, he says, because they are the “ultimate ambassador for the ocean and spark an emotional connection among people”. “The larger an animal is, the more you connect with it. That’s human psychology.”

He accepts that being freezing cold is part of his job, however painful. “Sometimes when I come to the surface, I struggle to speak because my lips are numb with the cold. I use a wetsuit often, because it is faster in the water. Speed is everything if you want to keep up with a whale. But sometimes we use drysuits which allow you to stay down for longer – you can stay in the water for half an hour with a drysuit.”

Heide believes his method of navigating the often treacherous Arctic conditions in a small sailing boat, Barba, helps him better connect with nature and people.

“If we were there in a €5m [£4.3m] state-of-the-art expedition vessel, it would be less impactful. In a small boat, you have to connect with nature and your life is governed by nature. You get sea spray in your face.

“Ernest Shackleton and his crew were out pushing the boundaries with the means they had at their disposal, with an adventurous spirit and a willingness to explore.”

After Blackbird, the traumatising spy-thriller bankrolled by and starring Irish dancer Michael Flatley, filmgoers thought they were safe – for a while – from bizarre and eccentrically acted dramas set in luxury paradises. But now, at the age of 22, actor and model Damian Hurley has written and directed a softcore erotic mystery drama set in the Caribbean starring his sexy mum, Elizabeth Hurley … to whom he gives a full-on sapphic love scene with a nightclub singer. As this woman’s head slinks south after a lingering kiss, Mr Hurley brings his camera very candidly indeed to what could only be described as an imminent moment of oral pleasure. We know the phrase Too Much Information … but what about Too Much Content? Too Much Freud? Or just … Too Much?

Hurley plays Lily, a woman both in mourning and in skimpy beach attire – or sometimes in a revealing athleisure two-piece, accessorised with diaphanous wrap. Lily’s daughter took her own life the previous year, drowning while in a bikini. Cue: upsetting flashback. But now Lily invites all the departed’s young friends to hang out at her palatial beachside hacienda along with her other daughter. This will bring healing. This will bring closure. This will bring gorgeous swimwear. But all these pouting people have awful sex-related secrets which may or may not reveal something about this woman’s terribly sad demise.

As for Liz herself, she brings serious décolletage energy to every scene and an overwhelming embonpoint dynamic to her husky line-readings. Once you get to the big reveal, you feel like you’ve sat through a hundred episodes of a saucy daytime soap with the saucy bits cut out. They could franchise out a sequel: Strictly Confidential in Dubai.

The mid-ocean ridge is where the Earth creates its outer skin. It’s called the boundary of creation. We knew there was life on the bottom of the ocean but not entire ecosystems supporting large animals until our expedition went down there in 1977.

First, we sent down an unmanned vehicle called Angus, which was essentially a camera system and strobe lights within a two-tonne steel cage. It was going down in the eternal darkness, slaloming back and forth like a skier down a mountain.

We were exploring the longest mountain range on Earth – the mid-ocean ridge. We were looking for heat, and we theorised that there would be vents in the ridge, but we never expected to see large concentrations of life. After 12 hours of taking thousands of photos, Angus came back up.

When we studied the photos we found that at about 2,500 metres deep, where we had detected a sudden increase in temperature, the water got cloudy. Then we suddenly saw clams – giant clams the size of dinner plates – and tube worms that were two or three metres tall.

It was like finding an oasis of life in the Sahara; it was like a rose garden. The room exploded with excitement onboard the ship when we saw the images. Scientists become children when they discover something – it was like we never left middle school.

The discovery solved the mystery of how life got a foothold on the planet, and it has led people to believe there is even more likely to be life elsewhere in our solar system. But we were not expecting to find a large ecosystem of life – we were all geologists.

We invited biologists but they didn’t want to go because they said there’s nothing going on there. We constantly remind them they weren’t there when we made this historic biological discovery; we have to rub it in.

The next morning, three people went down in a submersible to the spot where we had photographed the clams the day before to bring up samples. The pressure hull within the deep diving vehicles we used was tiny. Ours was about two metres in diameter and we stuffed three people in there. It was like working inside a Swiss watch.

When we brought the clams up to the surface, we realised they were functioning like no other organism we had seen before. When we opened them, we found that they had human-like blood. They looked more like beef than a clam – they weren’t white but red, full of haemoglobin and fleshy on the inside.

You’d expect this blood to be circulating nutrients and other resources between organ systems, and yet, unlike most clams, they had no internal organs, no mouths. It was a mystery how they were feeding themselves.

We looked under the microscope and found this very ancient bacterium, which wasn’t even named at the time, living inside their bodies. It turned out the clams were being fed by the bacterium. I called a friend and tried to describe to him what we were seeing, and he said: “That’s impossible.” I said: “I’m holding it in my hand.”

It was really funny because scientists usually talk constantly, and no one was talking. Everyone was trying to process it, thinking: “I don’t know what I just saw.” It was dumbfounding.

We didn’t really start to understand what was going on until we opened our water sample back on the ship. It was so strong in hydrogen sulphide – a corrosive gas that smells of rotten eggs – we had to open the portholes. We realised what we had found at the bottom of the ocean was a hot spring that had a chemistry that triggered life.

We were always taught that life had to live in a very narrow pH, and all of a sudden we were finding life in a very acidic environment. We realised that these clams and tube worms were actually ingesting the chemistry of the vents, using it as fuel. Their bacteria were harnessing the energy of hydrogen sulphide to fix carbon.

That just blew the socks off science because we had been told that all life on Earth of any major megafauna was due to photosynthesis. It proved that life can exist in much more hostile environments than we thought.

Underwater exploration has been my life’s work – I’ve done more than 170 deep-sea expeditions over a career of more than six decades.

I was born in Kansas. I’m the first of 13 generations of my family in America to go to college. When I discovered the Titanic in 1985, I became a big celebrity and went on all the talkshows. Days later my mom called and said: “We watched you on all the TV shows, and all the neighbours are calling, but son,” she said, “It’s too bad you found that rusty old boat. You discovered hydrothermal vents, but they’re only going to remember you for finding that old boat.”

And moms are never wrong … finding hydrothermal vents beats the hell out of finding the Titanic.

It helped us understand how life got a grip on this planet and how it could be elsewhere too. It opens the doors to life and intelligent life throughout the universe. When you look up at the galaxies, wave, because they’re waving back at you. Jupiter’s moon Europa and Saturn’s moon Enceladus have oceans far larger than ours. There should be life in those oceans. I hope we can get over there, but it would not be a place you want to live. There is no plan B for the human race.
