UK's Solena secures $6.7 mn for AI-designed biodegradable textile
Imperial spinout will scale its activity to help create a new generation of sustainable, high-performance textiles using an entirely new class of fibres.
Solena Materials has raised $6.7 million (£5.1 million) in seed funding, following a $4.1 million (£3.1 million) pre-seed funding round in 2022, that it will use to produce protein fibres at scale.
Imperial spinout Solena Materials has raised $6.7 million to scale up production of sustainable, biodegradable protein fibres designed using AI and engineered microbes. These novel fibres, offering high performance and lower environmental impact, could transform fashion and technical textiles. The investment will fund expansion and support partnerships with leading fashion brands.
The company uses AI techniques to custom-design fibres at the molecular level which are then produced using engineered microbes. Its AI techniques allow it to optimise performance characteristics of the fibres such as appearance, hand-feel and tensile strength, and could result in new and higher performing fashion, sports apparel, and technical textiles.
Solena's co-founder and CEO, Dr James MacDonald , developed the techniques behind the company as a researcher at Imperial in collaboration with his other co-founders. 'We're creating protein sequences that don't exist in nature to have the performance specifications we need while also being highly manufacturable,' he explained.
Professor Paul Freemont, Solena co-founder and Head of the Section of Structural and Synthetic Biology in Imperial's Department of Infectious Disease , said: 'This extraordinary technology is opening up a whole new paradigm in the design of protein fibres. James has created new protein molecules that can form fibres that currently don't exist. That's really exciting because no one has been able to do that before – we've always had to rely on what nature gave us. Now we're building our own protein fibres from first principles. This will be a paradigm shift.'
Because the microbes used to produce the fibres use renewable feedstocks, the company's fibres could also potentially be produced at a lower environmental cost than synthetic textiles made from petroleum and resource-intensive natural fibres. The fibres are also biodegradable, unlike traditional synthetic fibres such as polyester.
Solena launched in 2022 with premises in Imperial's White City Incubator and pre-seed investment from Insempra. It has now raised further funds in a round led by Sir David Harding, alongside SynBioVen and Insempra.
It will use the investment to move from premises in the I-HUB building on Imperial's White City Deep Tech Campus to a larger facility, with an ambition to stay close to Imperial. This will allow the company to scale production of its novel textile fibres in partnership with well-known fashion brands.
Professor Milo Shaffer, Solena co-founder and Chair in Materials Chemistry at Imperial , said: 'Solena is particularly exciting, not only as a new class of high performance sustainable fibres for a wide range of applications, but also as an example of a paradigm shift in accelerating materials discovery. The combination of computational design with rapid evaluation in fibre form, directly feeds to scaled up production and implementation, exploiting established textile technology.'
Dr MacDonald shared details of the investment at the SynBioBeta conference in California, near Imperial Global USA, a hub that is helping the university build links with partners such as businesses and investors in the US.

Maharashtra forms task force to integrate bus transport in MMR
The Maharashtra government has constituted a 12-member task force to prepare an integrated bus transport plan for the Mumbai Metropolitan Region (MMR), with the aim of enabling seamless travel through a unified single ticketing system. The task force will be headed by the General Manager of Brihanmumbai Electric Supply and Transport (BEST), while the Chief of the Transport and Traffic Department of the Mumbai Metropolitan Region Development Authority (MMRDA) will serve as its secretary. The ten other members will include senior officials from key municipal corporations such as the Thane Municipal Corporation, Brihanmumbai Municipal Corporation (BMC), Navi Mumbai Municipal Corporation, Vasai-Virar Municipal Corporation, and the Additional Metropolitan Commissioner of MMRDA. A government resolution (GR) issued by the Urban Development Department on Tuesday (June 10, 2025) stated that the committee was formed following a meeting of the Growth Hub Regulatory Board held a month ago, chaired by Deputy Chief Minister Devendra Fadnavis. The task force has been assigned the responsibility of drafting a comprehensive plan to integrate public bus transport services and enhance coordination among various civic-operated systems in the MMR, currently lacking a unified transport authority. The task force has been established under the Growth Hub Governing Board, which is also tasked with final approval of the Mumbai Metropolitan Region Economic Master Plan. The proposed single ticketing system is one of several initiatives under the wider economic strategy. According to the GR, the initiative aligns with NITI Aayog's Growth Hubs (G-HUB) policy, which aims to accelerate regional economic development by focusing on attracting foreign investment, encouraging startups, and creating employment opportunities. 'The policy recommendations focus on attracting and retaining foreign investment, promoting startups, and generating employment. They decided to roll out on a pilot basis in four urban regions, with the Mumbai Metropolitan Region in Maharashtra being one of them,' it stated.

Google rolls out buyout offers in US teams as AI spending takes priority
Google on Tuesday initiated a fresh round of voluntary buyout offers across multiple US-based departments, including the knowledge and information (K&I) unit, central engineering, marketing, communications, and research teams, according to a report by CNBC. The K&I division includes major departments such as Search, Advertising, and Commerce. A voluntary buyout—or voluntary exit programme (VEP)—is a financial incentive offered to employees to resign willingly, typically implemented as a cost-cutting or restructuring strategy. A Google spokesperson confirmed the initiative to CNBC, stating: 'Earlier this year, some of our teams introduced a voluntary exit program with severance for U.S.-based Googlers, and several more are now offering the program to support our important work ahead.' However, the exact number of affected employees has not been disclosed. 'You may leave if you don't feel energised': Fox memo Nick Fox, who has headed the K&I unit since an October 2023 reorganisation, addressed staff in a memo urging those who feel disconnected from the company's goals or struggling with performance expectations to consider the exit offer. 'I want to be very clear: If you're excited about your work, energised by the opportunity ahead, and performing well, I really (really!) hope you don't take this,' Fox wrote in the internal communication. 'On the other hand, this VEP offers a supportive exit path for those of you who don't feel aligned with our strategy, don't feel energised by your work, or are having difficulty meeting the expectations of your role.' The exit programme applies only to full-time US-based employees. In addition, remote workers within 50 miles of a Google office are being asked to return to the office under a hybrid schedule. Previous buyouts across teams This is not the first time Google has turned to buyouts. In January, its Platforms and Devices division—including Android, Chrome, and Pixel hardware—introduced a similar voluntary exit scheme. This was followed by the People Operations division in February, which offered mid- to senior-level staff up to 14 weeks of severance, plus one additional week per year of service. Legal and finance departments have also implemented buyout initiatives. Fox noted that he reviewed earlier programmes and received positive feedback from other teams before adopting the approach for the K&I unit. AI focus drives internal restructuring Google's increased use of voluntary exits reflects its broader strategy to reallocate resources toward artificial intelligence infrastructure. The company is also investing in internal training programmes focused on deploying practical AI tools across its products. Earlier this year, some employees welcomed the buyout option over abrupt layoffs. However, the buyout offers often come with return-to-office conditions. According to an April report by CNBC, some remote employees were told to resume in-office work to retain their roles and avoid further job uncertainty.

Google offers buyout: Why is the tech giant paying employees to leave?
Google on Tuesday is trimming its workforce by offering buyouts to employees across several divisions. The layoffs target teams across the company's knowledge and information (K&I) unit, central engineering units as well as marketing, research and communications teams, reported CNBC. The 'voluntary exit program' applies to the US-based employees. Some teams are also making it mandatory for remote employees who live within 50 miles of the company to come back to the office, according to the report. They will be expected to assume a hybrid work schedule 'in order to bring folks more together in-person,' said the company. Paying severance for silent exit 'Earlier this year, some of our teams introduced a voluntary exit program with severance for the US-based Googlers, and several more are now offering the program to support our important work ahead,' Google spokesperson Courtenay Mencini wrote in an emailed statement to CNBC.

It underwent a reorganisation in October last year which resulted in Google executive Nick Fox taking over the helm. Fox sent out a memo on Tuesday saying that 'employees who are not meeting expectations may want to take the buyout and those who are excited by their work and doing well will remain with the company', reported CNBC. What does Google executive's memo say? 'I want to be very clear: If you're excited about your work, energized by the opportunity ahead, and performing well, I really (really!) hope you don't take this! We have ambitious plans and tons to get done,' Fox wrote, according to the memo, which was reviewed by CNBC.

Fox added. 'AI Infra spending' is Google's top priority The buyouts come after the company's finance chief Anat Ashkenazi in October last year said that one of her top priorities would be to drive more cost cutting as Google expands its spending on artificial intelligence infrastructure in 2025. Google is also overhauling a popular internal learning platform to focus on teaching employees how to use modern AI tools in their work in a shift away from some of its nice-to-have programs to more business-essential offerings, as per the CNBC report. Buyouts are new-age layoffs Google has done multiple buyout offers in a few units this year, making it a preferred strategy to reduce employee count, marking a cultural shift from traditional layoffs.

At the time, employees said their access to company systems was unexpectedly cut off. Some of them were long-time employees, stellar performers or on medical or maternity leave, CNBC reported at the time. The full-time US-based employees of Platforms and Devices, which is the company's hardware unit, can apply for a buyout in January. This unit consists of 25,000 full-time employees working on Android, Chrome, ChromeOS, Google Photos, Google One and the Pixel devices People Operations, also known as the company's human resources department, offered voluntary buyouts in February. Google's legal and finance teams have also announced buyouts this year, a company spokesperson told CNBC. How much severance pay can employees expect? As part of the People Operations buyouts, mid to senior-level employees received severances of up to 14 weeks of salary and one additional week for every full year of service, said CNBC.
