Qatar Prints Landmark 3D‑Built Schools at Scale
Arabian Post Staff -Dubai
Qatar has embarked on the printing stage of an ambitious architectural endeavour, deploying what are now the world's largest 3D construction printers to build two public schools. Spearheaded by UCC Holding alongside the Public Works Authority, Ashghal, the project forms part of a broader plan to erect 14 new educational facilities under a public–private partnership, but these two structures alone span 40,000 m²—roughly 40 times larger than any previous 3D‑printed building worldwide.
Two custom-built BODXL printers supplied by Denmark's COBOD each measure 50 m in length, 30 m in width and 15 m in height—dimensions comparable to a Boeing 737 hangar—making them the largest construction printers ever deployed. The twin schools, each covering 20,000 m² on 100 × 100 m plots, are two-storey edifices designed to showcase scalable, next-gen educational infrastructure.

Extensive preparatory work preceded the launch, including site development, printer assembly and more than 100 full‑scale test prints at a Doha-based trial site using a BOD2 printer. These trials refined concrete mix formulations suited to Qatar's hot climate and developed bespoke nozzles to enhance precision. In May 2025, UCC engineers trained with COBOD specialists in print sequencing, structural layering and on‑site quality management, cementing Qatar's local expertise in advanced construction technology.
The project offers clear environmental and operational benefits over conventional construction. By reducing raw material waste, lowering concrete consumption and cutting carbon emissions, 3D printing aligns with sustainable development goals. On‑site production cuts transport requirements and supply chain risk, while round‑the‑clock printing—including overnight operations—helps avoid thermal stress, minimises dust and noise and accelerates timelines.
Architectural design draws inspiration from Qatar's landscape: sweeping, dune‑inspired curves are possible only through 3D printing's geometric flexibility—a feat difficult and costly via traditional means. Scheduled to be completed by December 2025, the initiative is expected to redefine sustainable infrastructure while fortifying Qatar's position as a global innovation hub.
Co‑founder of COBOD, Henrik Lund‑Nielsen, remarked that this marks both a technological milestone and an environmental turning point in building methodology. A spokesperson at UCC Holding said the venture 'sets a global benchmark' in construction, as Qatar continues to drive pioneering engineering projects across the Gulf.

How to declutter your home with this Dubai-based professional organiser
Salam Shaban, professional Dubai-based organizer and founder of Tidymess, discusses how you can reset your space for a successful 2023. What inspired you to enter the organisational space? I always loved organising, so it was something I was eager to learn more about. After seeing the amazing work of Marie Kondo I felt inspired to pursue it more seriously. Once I created a system that worked so well for myself and my family, I felt it was important to share it with others. You launched Tidymess a few years back. What was the initial response to the concept? At the time, it was a very new concept. I found myself having to explain it to most people I knew. Once people started to see my work they thought it was a great idea and encouraged me to pursue it. How have things evolved since you launched? I've been so lucky to have received such a phenomenal response from my clients and social media. This has really helped me grow my business. Every day people hire me and my team to help organize their spaces. We immerse ourselves in their homes and move through their spaces tailoring a highly-functional system. In the beginning, it was difficult to take on large projects, but as my team grew, we are now capable of really helping our clients organise as many spaces in their homes as they need. For those who are having a refresh for a new year, what are your top tips to start organising your space and life? Before buying anything new, take a minute or two to think about where it is going to live in your home and life. Think about how long you will need this item and what will happen to it in the future when you no longer do it. If it is something that you feel will add no real value to your space, then you most probably don't need it. View this post on Instagram A post shared by Tidymess (@tidymess_dxb) A particular place where clutter can build is your wardrobe. What is the best way to approach decluttering this space? Ask yourselves questions such as: When was the last time you wore it?; Is it in good condition?; Does it have sentimental value?; Have you worn it in the past year?; Does it fit you properly? Your answers will help you decide whether you want to keep, donate or store away your item. Over the years, what have been the hurdles you've experienced when building the Tidymess concept? Starting any business from scratch is a challenge. In my case, I was starting a business from scratch about a new concept that few people had heard of. I would say bringing my vision to life was a great challenge because it took a while for people to realize the necessity of adopting a new lifestyle for their homes as opposed to seeing my work as simply 'cleaning up' the house. What have been the key milestones? I would say my first milestone was when I was able to bring in a team to help me serve my clients better. Building a team gave me a sense of accomplishment that something I had started on my own was now growing into something more. My second milestone was after having my third child and realizing that I did not need to stop working. It took a lot of mental and emotional energy to see that it was okay for me to keep doing what I loved. Once I started taking on new projects again, I was so proud of myself and happy that I had not just let it go because of my new responsibilities and busy life. What does the future hold for Tidymess? Continue to grow and reach more people. Everyone can be a part of this concept. Whether they want to hire our services, buy our favourite products online or simply gain a few ideas from our social media page. I hope my team and I can help more people organize their spaces and love their homes. What will you be doing to reset your mindset and body for 2023? Keep finding that balance. As a mum of three and founder of a female-owned business, I find myself wearing many hats at once and that can quickly become overwhelming. I just need to keep finding that balance between my home life, work life and also those moments that are just for me.

AI‑Powered Phage Therapy Set to Tackle Antibiotic Resistance
Phagos, a Paris‑based biotech startup, is deploying an artificial‑intelligence model built on Amazon Web Services to accurately match bacteriophages with antibiotic‑resistant bacterial strains. This development marks a pivotal shift from arbitrary trial‑and‑error methods to precision medicine in combating infections that claim an estimated one million lives annually. The challenge of antibiotic resistance has spurred Phagos, co‑founded by microbiologist Adèle James and economist Alexandros Pantalis, to pursue alternative therapies. Phages are viruses that specifically infect bacteria, a property that enables targeted treatment without disrupting beneficial microorganisms. But identifying the right phage for a given pathogen has traditionally required labour‑intensive screening of millions of combinations. Phagos is leveraging AWS's Generative AI Accelerator Programme, which has provided them with cloud credits, embedded AWS architects and machine‑learning engineers, and dedicated mentorship, to build a generative AI platform capable of predicting effective pairings between phages and bacterial strains. The AI model has been trained on datasets from public repositories and proprietary lab results. ADVERTISEMENT 'We can now read into the DNA and see if there's going to be an interaction between a phage and a bacterium,' Pantalis explained. This capability bypasses exhaustive wet‑lab testing and accelerates the discovery pipeline. Phagos's strategy involves initial trials in animal health—shrimp, chicken, bovine, swine—with phages administered through water systems to curb infections in farm environments. James noted that reducing antibiotic use in livestock is critical, as drug‑resistant bacteria generated in farms can transfer to humans via environmental pathways. The startup's first validation came from a collaboration with an oyster farmer in France, where AI‑matched phages slashed mortality by 40 per cent. Technical infrastructure from AWS played a crucial role, with cloud experts helping to refine the system and scale it efficiently. 'We became much faster, and spent way less time figuring out how to set up our infrastructure,' James said. Globally, the antibiotic resistance crisis is projected to cause more deaths than cancer by mid‑century, with economic impacts exceeding US$1.5 trillion. By automating phage matching, Phagos aims to create personalised and adaptive therapies that evolve in tandem with bacterial mutations. Participation in AWS's 2024 accelerator—which selected just 80 startups from over 4,700 applicants—has provided Phagos not only with technical and financial support, but also exposure to industry networks and potential funding sources. The platform-as‑a‑service model being developed by Phagos positions the company as a pioneer in AI‑driven microbiological model building. One quarter of its team now focuses exclusively on data and machine learning, a rarity in biotech. Expansion plans are underway: the company intends to move into human therapeutic applications by 2030, while continuing its work in agriculture. It is also advancing bespoke phage therapies, distinguishing itself from generic phage cocktails pursued by competitors. While obstacles remain—such as regulatory pathways for phage-based treatments and the complexity of bacterial ecosystems—Phagos believes its AI model and cloud infrastructure provide a scalable solution. Each new phage cocktail generates data that feeds into the platform, enhancing future predictions.

Saudi Bank Unveils New Credit‑Card Rules to Drive Transparency
Arabian Post Staff -Dubai The Saudi Central Bank has introduced sweeping reforms in the rules governing credit-card issuance and operation, aiming to reduce consumer costs, bolster transparency and align with global standards. The changes include mandatory fee notifications, reduced cash withdrawal charges, capped international transaction fees and improved disclosures. SAMA will implement these updates within 30 to 90 days. Key changes include a requirement for issuers to send SMS alerts before any fee or term modification, allowing cardholders a 14-day window to cancel agreements without penalty under the updated terms. E-wallet top-ups using credit cards will now incur no charges, a move intended to incentivise digital payments. ADVERTISEMENT Cash withdrawals of SR2,500 or less will carry a maximum fee of 3% of the transaction value; those of SR2,500 or more are capped at SR75. Previously, cash advance fees applied sharply until SR5,000 with a flat SR75, and beyond that 3%, up to SR300—making the new cap notably more favourable for larger withdrawals. International purchases will now attract a clear 2% fee of the transaction amount. A notable enhancement allows customers to deposit amounts beyond their credit limit and withdraw them at any point without additional charges, enhancing flexibility and consumer agency. Account statements must now be issued via SMS at least 25 days before payment, detailing balances, due dates and fees. Immediate notifications must follow any credit-card transaction, including details such as merchant, amount and remaining limit. Issuers are also required to provide pre‑transaction tools for estimating international charges and reward benefits. Repayment provisions maintain consumer safeguards: a 25-day minimum grace period is mandated before term costs apply. The rules prohibit levying additional fees for full balance payments and outlining clear terms for minimum payments and their implications. These reforms are underpinned by standardised disclosure templates for fees and benefits, inclusive of promotional terms—a step towards consistency across the market. Issuers must emphasise APR, term costs and expiration timelines for rewards or promotions, with SMS reminders 14 days in advance. SAMA's emphasis on mandatory due diligence and creditworthiness checks prior to card issuance is reinforced under the new framework. Criteria now include explicit customer consent via authenticated channels, formal credit record assessments and eligibility conditions aligned with industry best practices. Procedures for supplementary cards, default reporting and dispute resolution have also been clarified. For example, the minimum repayment remains 5% of the due balance, and any default procedures must include consumer advisory services before legal or collection measures begin. SMS has been designated the primary channel for disclosures, with issuers obliged to inform customers of account activity, fee changes and promotional developments. Financial institutions must adhere to SAMA‑specified notification templates to promote uniformity and clarity. According to a senior official within SAMA, the goal is to 'establish minimum requirements to promote disclosure, transparency and fair practices, as well as to limit credit risk.' Industry reaction has been generally positive. Analysts from regional banks suggest the rules will 'enhance consumer protection while supporting digital payment growth.' Critics, however, note potential implementation challenges—particularly in updating existing systems to align with stricter notification and compliance requirements. The timing reflects SAMA's broader strategy to modernise the financial sector and accelerate digital payments as part of Saudi Vision 2030. A 2020 directive mandated real‑time notifications for debit card and e-wallet transactions, laying foundational infrastructure for today's enhanced SMS regime. Collaboration with global payment networks—such as Visa, MasterCard and American Express—has helped shape caps on international and cash advance fees. Banks and fintech firms are now preparing compliance roadmaps. One major lender has initiated system-wide updates to include the new SMS templates, fee calculators and balance‑flexibility features. Industry trade bodies are urging transparency in implementation timelines to ensure consumers are well informed ahead of the rollout. As SAMA positions Saudi Arabia's credit‑card framework at par with international best practice, key areas to monitor include transparency in third‑party charges, enforcement mechanisms for non-compliant issuers, and feedback from consumer‑protection advocates.
