Prince of Wales and Cate Blanchett don lab coats to see eco brand at work

William and the actress visited labs in Norwich on Thursday where Colorifix, a biotechnology firm, creates its textile dyes.
Colorifix, which was a finalist in William's Earthshot Prize in 2023, has developed a biological process that replaces the use of harmful chemicals in textile dyes.
Since it was founded in 2016, the brand has partnered with fashion brands including H&M and Pangaia.

As William and Blanchett were taken through each step of the process to make the eco-friendly dyes, the Prince of Wales asked Sophie Vaud, the head of microbial engineering, to provide a 'layman's version' of the science.
After identifying a colour created naturally by an animal or plant, Colorifix's scientists sequence the DNA of that organism to find out where the colour is coded in its genetics.
That DNA code is then translated into a safe microbe which is then fermented to grow, creating a dye that can be used on natural and synthetic fabrics.
Dyes made chemically have a negative impact on the environment as they seep into rivers, harming wildlife. The process also uses a large amount of water.
The Prince of Wales and Blanchett, a council member of the Earthshot Prize, were invited to observe DNA gel under a microscope and were shown diagrams analysing the effectiveness of the pigments.
'What if it explodes?' Blanchett, joked before looking at the sample.
'I'm not going to pretend I know what that drawing means,' William told the experts when being shown diagrams.
The pair were then taken through the fermentation process which is where the dye is produced in a small version which can be scaled up.

David Clarke, head of fermentation at Colorifix, which is based in Norwich Research Park on the edge of the city, said their fermentation to produce the dyes is 'just like brewing'.
'We use a genetically-engineered bacteria to produce the substance – in this case colourants. In the brewing industry it's ethanol.
'Traditional dyeing is very, very polluting. This is completely innocuous.'
William and Blanchett were wowed by the range of colours produced when shown samples in the colouration lab, especially a bright teal.
In that lab, the dyes are sampled on a range of fabrics and then washed and tumble dried to test how they work and if there is any run off.
Rebecca Hiscock, a colouration technician, showed them some of the samples.
'It's like Blue Peter – here's one I made earlier,' William said.
Meeting the rest of the Colorifix team, the Prince of Wales said: 'Sorry for all the stupid questions you'll hear about later.'
He complimented the staff for their 'fantastic' work since Colorifix got to the final of the Earthshot Prize two years ago.
The Prince of Wales is founder and president of the global environmental award and Blanchett helps pick the winners.
'It's going really well, and it's really exciting,' he said, while Blanchett told them their work was 'really inspiring'.

Crowds sing along in sun as Sting set to headline Isle of Wight Festival A total of 55,000 party-goers have crossed the Solent to reach Seaclose Park in Newport for the four-day event also being headlined by Stereophonics and Justin Timberlake. Sting (Image: PA ) Music-lovers have been singing along in the sunshine as Sting is set to headline the first full day of the Isle of Wight Festival. A total of 55,000 party-goers have crossed the Solent to reach Seaclose Park in Newport for the four-day event also being headlined by Stereophonics and Justin Timberlake. ‌ The Police frontman is headlining on Friday evening – the first night of the main stage – followed by Faithless. ‌ The gates opened on Thursday, with tribute band The Smyths being the first act to take to the Big Top stage, which also featured The Pigeon Detectives before headliner Example took over. A festival spokeswoman said: "With festival-goers suitably ready for the weekend of music, they descended back to the Big Top stage for The Pigeon Detectives, whose phenomenal live set featured songs from across their 20-year career and six albums that have made them a firm festival favourite. Article continues below "As the sun began to set on night one of the festival, Big Top headliner Example brought an electrifying, high energy set of hits from across his catalogue including Change The Way You Kiss Me, Kickstarts and more." John Giddings, who has run the festival since relaunching it in 2002 following the infamous events which ran from 1968 to 1970, said he goes with "gut feeling" when choosing the acts. The 72-year-old told the PA news agency: "You want to book acts that have a catalogue that's going to entertain an audience for an hour, hour-and-a-half, and, secondly, someone who's capable of performing to an audience of 50,000 people in a field, because they need to be able to project to entertain." Article continues below Other acts performing during the weekend include The Script, Jess Glynne, Clean Bandit, Supergrass, Example, The Corrs, Busted, and Texas.

Carole Middleton and King Charles share sweet moment as fans spot same thing

Our community members are treated to special offers, promotions and adverts from us and our partners. You can check out at any time. More info Royal Ascot has seen the turnout of the Royal family and their confidantes at the premiere Berkshire racing event, reveling in both the equestrian events and this pinnacle occasion on the social calendar. Despite key figures consistently partaking in Ascot's pomp since its commencement earlier in the week, Carole Middleton – mum to Princess Kate – was spotted indulging in the excitement on Wednesday. This came as a pleasant surprise especially after her daughter, Kate, decided against attending at the eleventh hour. While Kate's absence was noted, her mother, Carole, lost no time in enjoying the company of the royals, sharing laughs with King Charles and embracing her son-in-law, Prince William. It's not unusual for Carole and the extended Middleton family to be seen at significant Royal functions – think King Charles' coronation in 2023 – however, their presence in relaxed settings, visibly having a good time, is somewhat of a novelty. The jovial interaction between Charles and Carole caught the attention of Royal enthusiasts, particularly within the Royal suite where their camaraderie was unmistakable, sparking an array of heartwarming comments regarding their evident close-knit rapport, reports the Mirror. A fan expressed delight on X stating: "It's lovely to see them together," while another remarked fondly: "Love that they have a lovely warm relationship." A different Royal spectator chimed in with: "So nice to see. Good that they all get along so well." Another individual commented: "I love that when they're together, they're just in-laws. He's the King, but he's also her daughter's father-in-law and they share grandkids." Throughout the day, Prince William was also observed embracing his mother-in-law, suggesting a strong kinship between them, with William having become as integral to the Middleton family as Kate has to the Royal Family. Even though her daughter Kate dropped out of Royal Ascot, Carole Middleton still attended the event on its second day without her presence announced less than two hours before she was expected to join Prince William in the Royal procession. Given that Kate's name was already included in the programme for day two and had been circulated by Royal Ascot's social media channels, her sudden withdrawal raised eyebrows among the public. The Palace, nevertheless, promptly addressed the confusion about Kate's absence, stating it was down to a "miscommunication". A representative from Kensington Palace explained: "We notified Ascot that Her Royal Highness would not be attending. Unfortunately an inaccurate version of the carriage list was issued in error after that notification. The correct list was then circulated." It seems that the Prince and Princess of Wales have no plans to make further appearances during the festival. It is believed that Kate's absence is due to her striving to strike the right balance as she gradually resumes public-facing engagements, just months after announcing her cancer was in remission.

King Charles was later seen talking to the family during day four of the races. Sarah is an outspoken philanthropist, and has appeared at various royal events in recent years, despite divorcing Prince Andrew in 1996. The pair have two children together - Princess Eugenie and Princess Beatrice. It comes after the King suffered a streak of bad horseracing luck on day one of the event. The family horse, Reaching High, suffered a 'stinker' in the closing stages under jockey Ryan Moore. Meanwhile, his horse, Rainbows Edge, was smashed into a 7-2 favourite for the Kensington Palace Stakes. Earlier this week, Princess Kate pulled out of the event in a last minute decision as she adjusts to her royal duties.
