Best travel VPNs 2025: Expert-tested for streaming and avoiding censorship

You don't need to leave your privacy at home when you travel. A virtual private network (VPN) can keep your data safe, mask your IP address online, and provide you with protection while you're away from home. Trusted VPNs encrypt and route your traffic through dedicated networks, and you should always consider using one when you travel to avoid cyberthreats. VPNs can also circumvent censorship blocks in the country you visit, including the UK's new age verification laws, and may help you access

Beyond Retrieval: The Expanding Universe of Augmented Generation in AI

Introduction Standard large language models (LLMs) possess vast knowledge but struggle with limitations like hallucinations and accessing real-time information due to their static training data. This has spurred the development of dynamic AI architectures. Retrieval-Augmented Generation (RAG) has emerged as a key solution, integrating external knowledge into the generation process. However, the field is rapidly evolving beyond basic RAG. Newer models like RASG (Retrieval-Augmented Self-Generate

Will the UN finally broker a treaty to end plastic pollution?

To tackle what's been called the plastic "epidemic," the UN spun up a committee in 2022 tasked with brokering a legally binding global agreement. This ambitious treaty between UN member states was to address the full life cycle of plastics, from production to disposal: In short, define what counts as plastic pollution and curb the sorts of unchecked production that inevitably leads to it. But across five sessions since, countries have failed to reach a consensus on the text. What was meant to b

Compressing Icelandic name declension patterns into a 3.27 kB trie

Compressing Icelandic name declension patterns into a 3.27 kB trie August 2, 2025 Displaying personal names in Icelandic user interfaces is surprisingly hard. This is because of declension — a language feature where the forms of nouns change to communicate a syntactic function. In Icelandic, personal names have four forms, one for each of the grammatical cases of Icelandic nouns. Take the name “Guðmundur”: Grammatical case Form Nominative Guðmundur Accusative Guðmund Dative Guðmundi Genitive

China calls for the creation of a global AI organization

China wants to work with other countries and has laid out its plans for the global governance of artificial intelligence at the World Artificial Intelligence Conference (WAIC) in Shanghai. Li Qiang, the country's premier, warned about "technological monopolies" and said that AI could become "an exclusive game for a few countries and companies." As such, he proposed the creation of a "world AI cooperation organization" during the event. Li didn't specifically mention the United States when he ta

UK wants to weasel out of demand for Apple encryption back door

The UK government is reportedly set to back down from its battle with Apple to obtain back door access to secure user data protected by the company’s iCloud encryption. Victory hasn’t come through the courts, or government figures changing their minds on privacy matters, but thanks to ongoing pressure from the US during the two countries’ trade talks. Multiple unnamed UK officials told the Financial Times that the UK government is working on a way out. “The Home Office is basically going to hav

Xi Jinping warns against China's overinvestment in EVs and AI

Chinese President Xi Jinping has bluntly questioned a nationwide rush of investment into the AI and EV industries. As deflation anxiety grows and Trump’s trade war with China ramps up, the world’s second largest economy is turning to fast-growth tech industries to remain competitive. But Xi appears to think that the strategy is flawed. As reported by the Financial Times , China's President sent out a pointed message about over-investment at the two-day Central Urban Work Conference in Beijing.

Best travel VPNs 2025: Expert-tested for streaming and bypassing country blocks

You don't need to leave your privacy at home when you travel. A virtual private network (VPN) can keep your data safe, mask your online activities, and provide you with protection while you're away from home. Trusted VPNs encrypt and route your traffic through VPN networks, reducing the risk of internet protocol (IP) address monitoring, tracking, and data theft. You should always use a VPN when you travel, especially when relying on unknown Wi-Fi connections, as it's impossible to know what cyb

The first babies have been born following “simplified” IVF in a mobile lab

While IVF is increasingly commonplace in wealthy countries—around 12% of all births in Spain result from such procedures—it remains expensive and isn’t always covered by insurance or national health providers. And it’s even less accessible in low-income countries—especially for people who live in rural areas. People often assume that countries with high birth rates don’t need access to fertility treatments, says Gerhard Boshoff, an embryologist at the University of Pretoria in South Africa. Sub

Trump’s next tariffs will target South Korea and Japan

President Donald Trump plans to impose a 25 percent tariff on goods imported from South Korea and Japan. The levy will go into effect on August 1st, which is when the Trump administration will begin enforcing sweeping tariffs on a wider swath of countries that fail to reach a trade agreement with the US. The US was set to begin imposing its “Libera

Spain and Brazil push global action to tax the super-rich and curb inequality

Presented during the UN’s 4th International Conference on Financing for Development – taking place this week in Sevilla, Spain – the proposal highlights a growing problem: the richest individuals often contribute less to public finances than ordinary taxpayers, thanks to lower effective tax rates and legal loopholes. “Our countries need more and more public revenues to meet their needs. Inequality is a problem everywhere and the richest pay less than the middle class – even less than lower-inco

Elon Musk Is Back at Tesla, but the Magic Might Be Gone

Elon Musk and Tesla. Tesla and Elon Musk. The future of America’s largest electric vehicle manufacturer has always been tied to its charismatic and controversial CEO. Conversely, a significant portion of the self-described Techno King’s immense fortune is built on Tesla. Their destinies are linked. As Musk goes, so goes Tesla. A month after his chaotic exit from the Trump administration, the CEO has returned to the company full time, attempting to stabilize a brand whose reputation has been bad

Nearly 20% of cancer drugs defective in four African nations

Across Africa, cancer medications have been found to be substandard or counterfeit. That means people are being given medicine that may not work, or that could even cause them harm. An alarming number of people across Africa may be taking cancer drugs that don't contain the vital ingredients needed to contain or reduce their disease. It's a concerning finding with roots in a complex problem: how to regulate a range of therapeutics across the continent. A US and pan-African research group publ

G7 agrees to exempt U.S. multinationals from global minimum tax

The Group of Seven nations said on Saturday (June 28, 2025) they have agreed to exempt U.S. multinational companies from a global minimum tax imposed by other countries — a win for President Donald Trump's government, which pushed hard for the compromise. The deal will see U.S. companies benefit from a "side-by-side" solution under which they will only be taxed at home, on both domestic and foreign profits, the G7 said in a statement released by Canada, which holds the group's rotating presiden

Muvera: Making multi-vector retrieval as fast as single-vector search

Neural embedding models have become a cornerstone of modern information retrieval (IR). Given a query from a user (e.g., “How tall is Mt Everest?”), the goal of IR is to find information relevant to the query from a very large collection of data (e.g., the billions of documents, images, or videos on the Web). Embedding models transform each datapoint into a single-vector “embedding”, such that semantically similar datapoints are transformed into mathematically similar vectors. The embeddings are

Ask HN: Anyone Using Augmented Reality, VR, Glasses, Helmets etc. in Industry?

Since Google Glass made its debut in 2012, there's been a fair amount of hype around augmented reality and related tech coming into its own in industry, presumably enhancing worker productivity and capabilities. But I've heard and seen so little use in any industries. I would have thought at a minimum that having access to hands-free information retrieval (e.g. blueprints, instructions, notes, etc), video chat and calls for point-of-view sharing, etc would be quite useful for a number of indust

Devil May Cry and the early Mortal Kombat games join GOG’s Preservation Program

GOG’s Preservation Program launched in late 2024 and the number of included games has doubled since the initial wave, currently sitting at 183. The latest headline-grabbing additions are the first four mainline Devil May Cry games and Mortal Kombat 1+2+3.

Apple’s Journal app is coming to iPad and Mac with big upgrades

Apple’s Journal app is coming to the iPad and Mac as part of iPadOS 26 and macOS Tahoe, and several brand new features will be included too—even on iPhone. Journal app is included with iPadOS 26 and macOS Tahoe Journal first debuted in iOS 17.2 as a brand new iPhone app, but many expected it to go cross-platform as early as iOS 18 the following year. It’s taken longer than expected, but soon, Apple’s Journal app will no longer be iPhone-only. iPadOS 26 and macOS Tahoe both include Journal as

The World Birth Rate Is Now Dropping Precipitously

Image by Getty / Futurism Studies Whoever wrote in the Book of Genesis "be fruitful and multiply" never accounted for the cost of children these days, especially when you factor in expenses like college tuition, sports, tutors, clothes and childcare. And that's one of the reasons why people are having less kids, according to new reporting from the BBC. A new paper from the United Nations Population Fund (UNFPA) has revealed that one in five adults in 14 countries don't have, or think they won

The best VPN services of 2025: Expert tested and reviewed

Virtual private networks (VPNs) encrypt your data and hide your IP address. But there is far more to VPNs than that: they are essential tools to stop others from spying on your online activities, and they can help protect your sensitive information from theft. A VPN is vital when you are traveling or when you have to use public Wi-Fi networks. They forge an encrypted tunnel between your device and the service you are trying to access, which can prevent eavesdropping and stop you from being so e
