Sparxell launches first industrial textile ink made without dyes or plastics
According to Sparxell, this is the world's first commercial ink that eliminates both chemical dyes and mineral-based additives while still meeting the performance standards required for large-scale textile production. The product is designed to appeal to a wide range of users—from independent designers to major global fashion brands.
The color system draws inspiration from nature's own palette, specifically the structural coloration found in the wings of the Morpho butterfly. Rather than relying on artificial colorants, Sparxell's ink generates color through microscopic structures derived from plant-based cellulose. These structures manipulate light to produce vibrant, lasting hues.
'This launch opens the door for manufacturers to access high-performance color technology without compromising sustainability,' said Benjamin Droguet, co-founder and CEO of Sparxell. 'For too long, vibrant color has come at the planet's expense. Our goal is to make bio-based color a new industry standard—and this is just the beginning.'
The first pigment available in this range is blue, offered in both matte and glossy finishes. Orders and industrial integration will be managed by Positive Materials, which will also oversee implementation within existing manufacturing systems.
A printed cotton T-shirt made exclusively with Sparxell's new pigment is scheduled to debut in Europe this September. The company has announced plans to expand its color range over the coming months, offering broader customisation options and a complete spectrum of shades for the industry.
Droguet and co-founder Silvia Vignoli developed Sparxell's technology during their research at the University of Cambridge. Their partnership with Positive Materials transformed it from a lab-scale prototype into a full-scale industrial application.
'Our collaboration with Sparxell is exactly the kind of innovation the fashion industry needs,' said Elsa Parente, co-CEO and CTO of Positive Materials. 'We're offering brands a sustainable color solution that's as accessible and effective as conventional options—minus the environmental harm. The pigments are 100% biodegradable and entirely free of toxic chemicals.'

Isak told to train alone by Newcastle
The 25-year-old has been linked with a British transfer record move to Liverpool after failing to feature in Newcastle's pre-season preparations. Isak missed the Magpies' trip to Singapore and South Korea, citing a minor thigh injury, and instead flew to Spain to train at former club Real Sociedad. He has since returned to Tyneside but Sky Sports reported that Isak was instructed to train after the rest of the squad had departed on Wednesday. "You have to earn the right to train with us. We are Newcastle United," Howe told reporters earlier in pre-season. "We will make sure that any player earns the right to train with the group. No player can expect to act poorly and train with the group as normal." Liverpool have seen a £110 million ($146 million) bid for Isak rejected, according to reports, with Newcastle seeking closer to £150 million. Another major hurdle to any deal is Newcastle's ongoing struggles to finalise a deal to replace Isak. They face competition from Manchester United for RB Leipzig striker Benjamin Sesko after missing out on Joao Pedro, Hugo Ekitike and Liam Delap earlier in the window. Liverpool have already splashed out over £250 million this window on Ekitike, Florian Wirtz, Milos Kerkez and Jeremie Frimpong. However, they have also recouped major funds from the sales of Luis Diaz, Jarell Quansah, Caoimhin Kelleher, Trent Alexander-Arnold and Tyler Morton. And Darwin Nunez is close to a £46 million move to Saudi side Al Hilal that would free up more resources and space in the squad for another bid to sign Isak. Since joining Newcastle for £63 million in 2022, Isak has scored 62 times in 109 appearances, including the goal that secured the club's first domestic trophy for 70 years in the League Cup final against Liverpool in March.

Spain's housing crisis deepens: residents' anger is rising
Since 2010, housing prices in the European Union have surged by over 50% on average, while rents have climbed by 26%. Spain is among the hardest-hit nations, with rents increasing by up to 80% in the past decade. This is a crisis caused by a cocktail of scarce housing supply, inflated construction costs, the boom in short-term rentals, and foreign investor speculation. 'Barcelona is a city full of tourists. Rents are extortionate,' says Rosario Castelló, a longtime resident and member of the tenants' union, Sindicat de Llogateres. She faces eviction after her apartment block was purchased by Vandor Group, a subsidiary of British investment fund Patron Capital. 'I've lived in my flat for 26 years,' explains Rosario. 'It's where I raised my children, and where I have my clothing brand Pinku No Kuma,' she says showing the dresses she designs with her daughter. 'And Vandor wants to take my house away from me, along with everything I've achieved here,' she adds. Rosario is the last of the building's former tenants. All the other flats were turned into co-living spaces, rented to foreigners on short term leases. 'Vulture funds are massively buying entire buildings for speculation. And they're throwing us all out,' storms Castelló. 'It must stop.' Despite her lease having expired, she refuses to leave and is in legal proceedings with the owner to which she still pays rent. 'They offered me a small fee to get me out,' she explains, 'but rental prices are extortionate. I have nowhere to go.' Across Barcelona, residents like Rosario are banding together. Supported by the Sindicat de Llogateres, they are fighting to avoid evictions and pressure public authorities to intervene. 'There is a total lack of protection for the right to housing,' exclaims Martina Ges Torra, another member of the tenants' union. 'We will collectively defend this right.' The Spanish government is trying to curb the crisis. Measures include plans to remove 65,000 Airbnb listings, increase taxes on property purchases by non-EU nationals, and enforce rental caps. 'We have started to regulate the rise in rental prices,' says Barcelona's Mayor, Jaume Collboni, noting an 8% price drop in Barcelona. Another sweeping measure will eliminate all Airbnb apartments in the city by 2028, returning 10,000 homes to residential use. 'And in Catalonia, short-term rentals will be subject to the same price cap,' adds the mayor. 'This means a huge drop in profitability for investment funds – it's a deterrent.' Jaume Collboni is leading the 'Mayors for Housing Alliance' initiative, involving 15 major European cities. They have presented the EU with a European Housing Action Plan urging Brussels to invest in affordable housing and exempt such spending from the limitations of state aid rules. 'The European Commission must act,' insists Collboni. 'If citizens see that European institutions aren't addressing a problem of such magnitude, it could trigger a crisis of legitimacy,' he says, concluding: 'It's not just a social issue. The future of the European project, and of democracy itself, are also at stake.'

Liverpool set to cut losses with Nunez move to Saudi: reports
Nunez joined the Reds for an initial 75 million euros ($87 million, £65 million) from Benfica three years ago but has failed to live up to that price tag. The Uruguayan has scored 40 goals in 143 appearances but slipped down the pecking order at Anfield under both Jurgen Klopp and Arne Slot. According to transfer specialist Fabrizio Romano, Al Hilal will pay an initial 53 million euros for the 26-year-old. Nunez was likely to play even less this season after Liverpool signed Hugo Ekitike and Florian Wirtz as part of a 300 million euro spending spree that also includes full-backs Milos Kerkez and Jeremie Frimpong. However, the club could still break the British transfer record by signing Isak, with Newcastle reportedly demanding a fee of up to £150 million for the Swedish striker. The sale of Nunez would take Liverpool's income for transfer sales this window to nearly 200 million euros after the departures of Luis Diaz, Jarell Quansah, Caoimhin Kelleher, Trent Alexander-Arnold and Tyler Morton. Harvey Elliott is also attracting interest from RB Leipzig, with Liverpool wanting at least 45 million euros for the England midfielder. Nunez would become the latest big name to join Al Hilal, who shocked Manchester City to reach the quarter-finals of the recent Club World Cup. Coached by former Inter Milan boss Simone Inzaghi, the Saudi club's squad includes Portuguese internationals Ruben Neves and Joao Cancelo, Senegal captain Kalidou Koulibaly and former Fulham striker Aleksandar Mitrovic.
