Pioneering teenagers win acclaim for invention that could change the future of clean water: 'We'll refine our prototype'
Earlier this month, Tomáš Čermák, an 18-year-old from the Czech Republic, and Anna Podmanická, a 19-year-old from Slovakia, were named the European winners of The Earth Prize. The two were recognized for their invention, PURA, which uses light and plasma to purify wastewater.
As Tech.EU writes, PURA is an "energy-efficient, cost-effective solution [that] could transform water purification and ensure a healthier future."
Podmanická's research specializes in water purification using photocatalysis, in which light sets off a chemical reaction that breaks down organic matter at a molecular level, leaving water and carbon dioxide behind. Čermák researches how cold plasma can destroy pollutants and bacteria, and they combined their specialties to create PURA.
Tech.EU reports that PURA is already working on a small scale, removing impurities from wastewater and making it suitable for drinking water and other household uses.
"Our next step is to scale PURA," Cermak said in a video accepting the award. "We'll refine our prototype, test it in real-world conditions, engage students, and work with policymakers to lay groundwork for this new technology."
Finding an affordable way to bring clean water to all people would truly change the world. The United Nations estimates that 2 billion people, or roughly 25% of the world's population, don't have access to clean drinking water. And recent studies show that PFAS, or "forever chemicals," are prevalent in drinking water globally.
The Earth Prize is an international competition, awarding teenagers who develop solutions that move the world toward environmental sustainability. Each of the seven regional winners, such as Čermák and Podmanická, receives $12,500 to help implement their idea.
A public vote determines the global grand champion, with the winner announced in late April. Previous projects from the competition include an AI-powered wildfire sensor, a tool that helps predict flood patterns, and technology that uses plasma to boost crop yields and create eco-friendly fertilizer.

2 Artificial Intelligence (AI) Stocks With High Conviction
Key Points Spending on artificial intelligence could reach an astounding $4.8 trillion by 2033. Nvidia's GPUs are critical for the training and deployment of complex AI models. AI developers want the best cloud infrastructure, and Amazon leads in this area. 10 stocks we like better than Nvidia › Fortunes have been made by investing in artificial intelligence (AI) stocks. But there's still a lot of room left to go. The United Nations, for instance, believes that the AI market will grow from $189 billion worldwide in 2023 to nearly $5 trillion by 2033. Want to make sure your portfolio benefits? The two AI stocks below are for you. Nvidia remains the smartest AI investment When it comes to AI stocks, Nvidia (NASDAQ: NVDA) is king. Even if you're already familiar with this stock, there's a good chance that shares are much cheaper than you realize. If you've been following the AI market, you'll know that Nvidia is the most valuable GPU maker in the world. GPUs sit at the heart of the AI revolution. They're critical for training and deploying complex AI models. They also make it possible for end users to access these models en masse from anywhere in the world. Right now, Nvidia's GPUs dominate the market. The firm has an estimated 90% market share for AI GPUs. Its performance and ecosystem advantages have granted the company the highest gross margins in the industry. Wall Street analysts are unsurprisingly excited. Wedbush Securities analyst Dan Ives believes Nvidia's market cap will surge to $5 trillion within months. The biggest near-term catalyst: the decision by the U.S. government to allow Nvidia's new GPUs to be exported to China, a country that previously accounted for around 13% of the company's sales. While shares are expensive based on trailing earnings, the stock trades at just 39 times forward earnings. Considering the AI boom is expected to persist for a decade or more, expect Nvidia to maintain double-digit annual growth rates for years to come. This should quickly eat into the upfront valuation premium, making shares a relative bargain for patient investors. Amazon is an artificial intelligence powerhouse Apart from Nvidia, Amazon (NASDAQ: AMZN) stock looks like one of the best ways to invest in the AI revolution over the long term. That's because its most profitable business segment, Amazon Web Services, sits at the center of everything AI. We've already discussed how Nvidia's GPUs sit between AI developers and the end users themselves. But there's one other industry that also sits at the center of the action: cloud infrastructure providers. Most estimates believe Amazon's AWS division is the largest cloud infrastructure provider in the world. Data compiled by Statista gives AWS a 30% global market share, nearly as much as the next two competitors combined. While the data center industry is a bit more commoditized than the GPU market, there's clear differentiation by the players that can afford to invest at scale. Developers -- AI developers in particular -- want the best infrastructure possible. That includes the best hardware and the most locations from a geographic perspective. This makes it quicker, cheaper, and more convenient for customers. As the largest cloud provider in the world, Amazon is second to none in its ability to invest and expand its network. This should continue to place AWS at the center of increased spending. "Companies are spending and they're spending more, and they plan to spend even more," Baird analyst Colin Sebastian recently told GeekWire. "We did a survey last month of 100 corporations, and 87% of them said they will increase spending on Gen AI over the next year -- and a grand total of zero out of 100 said they would spend less." The AI spending boom is real. Demand should grow by 20% to 30% annually for years to come. With Amazon trading at 37 times earnings, most of its growth in this area is masked by its relatively slower growing e-commerce division. But as AWS becomes a bigger driver of Amazon's overall business, we could see growth rates accelerate, making shares a relative bargain in hindsight. Should you invest $1,000 in Nvidia right now?

China releases AI action plan days after the U.S. as global tech race heats up
SHANGHAI — The tech race between the world's two largest economies just intensified. China on Saturday released a global action plan for artificial intelligence, calling for international cooperation on tech development and regulation. The news came as the annual state-organized World Artificial Intelligence Conference kicked off in Shanghai with an opening speech by Premier Li Qiang, who announced that the Chinese government has proposed the establishment of a global AI cooperation organization, according to an official readout. Days earlier, U.S. President Donald Trump announced an American action plan for AI that included calls to reduce alleged "woke" bias in AI models and support the deployment of U.S. tech overseas. "The two camps are now being formed," said George Chen, partner at the Asia Group and co-chair of the digital practice. "China clearly wants to stick to the multilateral approach while the U.S. wants to build its own camp, very much targeting the rise of China in the field of AI," Chen said. He noted how China may attract participants from its Belt and Road Initiative, while the U.S. will likely have the support of its allies, such as Japan and Australia. In his speech, Premier Li emphasized China's "AI plus" plan for integrating the tech across industries and said the country was willing to help other nations with the technology, especially in the Global South. The category loosely refers to less developed economies, especially countries outside the U.S. and European orbits. Since 2022, the U.S. has sought to restrict China's access to advanced semiconductors for training AI models. Earlier this month, U.S. chipmaker Nvidia said the U.S. was allowing it to resume shipments of a less advanced H20 chip to China after a roughly three-month pause. However, China has been developing homegrown alternatives, which Nvidia CEO Jensen Huang both praised and described as "formidable" during his third trip to China this month. Former Google CEO Eric Schmidt met with Shanghai Party Secretary Chen Jining on Thursday in the city ahead of the AI conference, according to a city announcement. Schmidt did not immediately respond to a CNBC request for comment.

NS&I to deploy SBS' cloud-native core system
The National Savings and Investments (NS&I), a government-owned savings bank in the UK, has partnered with global financial technology firm SBS to upgrade its core banking and payments systems. This initiative is part of NS&I's Transformation Programme, which includes a contract with Atos, a digital transformation company. In this context, SBS cited a report by Celent, which forecasts that European retail banks will increase their cloud investments by 57.5% by 2030, reaching a total of $12.6bn. NS&I's internal infrastructure supports more than 24 million customers and manages changes to savings rates while addressing customer interactions. The implementation of SBS's digital, cloud-native core banking platform is expected to enhance operational efficiencies, as well as improve product and service delivery for NS&I. SBS CEO Eric Bierry said: 'NS&I's transformation program is evidence that it is possible for banks to execute this transformation—and doing so sets them up to drive otherwise unattainable efficiencies and experiences.' In collaboration with Atos, IBM, and Sopra Steria, NS&I is working to digitise its retail banking operations. The new SBP Digital Core platform from SBS will replace the existing core system, providing a cloud-native infrastructure for all retail banking and payment services. The SBP Digital Core is a cloud-native, composable banking solution that utilises latest technology and data to enable banks to deliver personalised banking experiences while adhering to regulatory standards. Transitioning to the SBP Digital Core will allow NS&I to leverage the flexibility and scalability of AWS's cloud environment, facilitating frequent adjustments to data storage and infrastructure as required. Unlike traditional core systems, which are often difficult to update, SBS's cloud and Software-as-a-Service (SaaS) solution provides regular automatic updates, according to the tech company. NS&I chief operating officer Matt Smith said: 'NS&I's transformation programme will help to deliver the digital experiences that our customers expect, while still ensuring there is help and support for those who need it.' The SBP Digital Core is part of a comprehensive suite of retail banking solutions offered by SBS. These are utilised by more than 1,500 banks across Europe, the Middle East, and Africa. "NS&I to deploy SBS' cloud-native core system" was originally created and published by Retail Banker International, a GlobalData owned brand.
