Studies show that gut health is on the decline, increasing the risk of a range of diseases. Reporting for BBC Tech Now, Jacqui Wakefield meets the researchers using new gut-on-chip technology to find out why, and how to fix it.

Google has removed a number of its artificial intelligence health summaries after an investigation found that false or misleading information was reportedly being provided. Earlier this month the Guardian found issues with multiple health-related AI Overview snapshots, which use generative AI to summarise key information at the top of search results. In one example, the newspaper said that when asked the question “what is the normal range for liver blood tests”, the AI did not account for sufficient context, nor the nationality, sex, ethnicity or age of patients in response.
Investors are moving away from Big Tech, in an epic rotation that has left a popular exchange-traded fund that focuses on such stocks on track for its longest monthly losing streak since 2023. While Big Tech stocks have weighed on the S&P 500 index this year, investors are rotating their money into other pockets of the market. That’s strengthening the market’s breadth, or the different kinds of stocks participating in the rally, and helping lift it to record peaks in 2026.
Cyclical sectors such as materials and industrials, which tend to benefit from optimism about the U.S. economy, have done well. Yet this past week, a traditionally defensive area of the market stood out with strong performance, even as investors continued to anticipate economic growth.
Small business productivity will skyrocket as business owners use AI-enhanced automations for everything from marketing to invoicing and scheduling, to customer communications. Beyond that, the insights these automations produce, once only available to enterprises, create the opportunity for them to make data-driven decisions and anticipate business demands in ways they never could have before. A recent Thryv (THRY) survey found more than half of SMBs are using AI, most of them daily, and 58% report saving 20+ hours per month. It feels like the small business digital transformation is now accelerating into the later innings. Joe Walsh, CEO, Thryv

Despite being advertised as the holy grail for businesses, embracing AI doesn’t mean a company will automatically experience improvements. A new survey that questioned thousands of CEOs found that more than half admit to seeing no significant financial benefit from AI to date. Professional services network PwC’s latest Global CEO survey was completed by 4,454 Chief Executive Officers across 95 countries and territories. Unsurprisingly, a lot of the questions are related to AI. Most companies have introduced the technology into their businesses to varying extents, but 56% of CEOs say it hasn’t produced any cost or revenue benefits.

The speed at which blood loss can become fatal has long challenged both military medics and trauma surgeons. Now, researchers at the Korea Advanced Institute of Science and Technology (KAIST) have created a powder-based hemostat that forms an impenetrable hydrogel barrier in just one second when applied to a wound.

China has more wind capacity than any other country in the world and has twice as much capacity under construction than the rest of the world combined. China’s wind generation in 2024 equaled 40 percent of global wind generation, according to a 2025 report from think tank Ember Energy. It is also building 180 gigawatts of large solar projects and 159 gigawatts of large wind projects, which together amount to nearly two-thirds of the capacity coming online worldwide, an analysis from Global Energy Monitor says.

While the AI world has been buzzing about the power of Google’s Gemini 3 and the coding finesse of Claude 4.5, leaks suggest OpenAI is preparing a “tactical strike” with GPT-5.3. This isn’t just a minor patch; it’s an attempt to reclaim the crown by focusing on what insiders call “cognitive density” — making the AI smarter and faster without simply increasing its size. According to leaks shared by multiple sources, the new version is codenamed “Garlic.” The name is a metaphor for the model’s design: just as a single clove of garlic can flavor an entire dish, this model is built to provide concentrated intelligence without the massive computational weight of its predecessors. Rather than chasing “ever-larger parameter counts,” OpenAI is reportedly betting on a technique called Enhanced Pre-Training Efficiency (EPTE). This process “prunes” redundant data during training, resulting in a model that is physically smaller but retains the world knowledge of a much larger system. This shift is expected to lead to faster response times and significantly lower costs for developers.
OpenAI’s GPT-5.3 Leak Hints at a Smarter, Faster, Cheaper AI
Over the last 15 months, two major developments forced Sam’s hand. 1) Compute costs continued to explode as NVDA demanded a 70% gross margin and more and more chips were stuffed into producing the same mediocre outputs. 2) Competition remained relentless as many free LLM engines were able to match or exceed ChatGPT’s capabilities. Examples include, Claude 3.5 Sonnet (October 2024 v2) outperformed GPT-4o on SWE-bench verified (a benchmark for solving real-world GitHub issues), scoring 49.0% vs. GPT-4o’s 41.7%. DeepSeek-V3 (Dec 2024) beat GPT-4o on the MATH-500 benchmark (90.2% vs. 76.6%). Grok-3 reported a score of 93.3% on the AIME 2025 (math competition), far higher than ChatGPT. Gemini 3.0 Pro currently outperforms ChatGPT in user preferences and retrieving “needle in a haystack” information. While one might think that ChatGPT would delay monetization because of the series of defeats, we believe that their window of even attempting ad-based monetization was closing fast.

Medieval alchemists dreamed of transmuting lead into gold. Today, we know that lead and gold are different elements, and no amount of chemistry can turn one into the other. But our modern knowledge tells us the basic difference between an atom of lead and an atom of gold: the lead atom contains exactly three more protons. So can we create a gold atom by simply pulling three protons out of a lead atom? As it turns out, we can.

Political leaders could soon launch swarms of human-imitating AI agents to reshape public opinion in a way that threatens to undermine democracy, a high profile group of experts in AI and online misinformation has warned. The Nobel peace prize-winning free-speech activist Maria Ressa, and leading AI and social science researchers from Berkeley, Harvard, Oxford, Cambridge and Yale are among a global consortium flagging the new “disruptive threat” posed by hard-to-detect, malicious “AI swarms” infesting social media and messaging channels.

Not all fat is bad for you and some extra weight around your stomach could play a vital role in fighting infections and inflammation, a study has suggested. Excess fat around the belly and internal organs, known as visceral fat, has long been seen as harmful. It’s associated with type 2 diabetes, heart disease, some types of cancer, stroke and high blood pressure. But researchers at the Karolinska Institute in Sweden have suggested “abdominal fat is not a uniform issue” and some types of fat can be beneficial.

Businesses are acting fast to adopt agentic AI – artificial intelligence systems that work without human guidance – but have been much slower to put governance in place to oversee them, a new survey shows. That mismatch is a major source of risk in AI adoption. In my view, it’s also a business opportunity. I’m a professor of management information systems at Drexel University’s LeBow College of Business, which recently surveyed more than 500 data professionals through its Center for Applied AI & Business Analytics. We found that 41% of organizations are using agentic AI in their daily operations. These aren’t just pilot projects or one-off tests. They’re part of regular workflows..
Companies are already using agentic AI to make decisions, but governance is lagging behind
Imagine going to the hospital for a bacterial ear infection and hearing your doctor say, “We’re out of options.” It may sound dramatic, but antibiotic resistance is pushing that scenario closer to becoming reality for an increasing number of people. In 2016, a woman from Nevada died from a bacterial infection that was resistant to all 26 antibiotics that were available in the United States at that time. The U.S. alone sees more than 2.8 million antibiotic-resistant illnesses each year. Globally, antimicrobial resistance is linked to nearly 5 million deaths annually.
In 2000, China produced only one-third of the amount of electrical power that the United States did; by 2024, it produced nearly two and a half times U.S. levels.

Brillant curation of these developments. The GPT-5.3 leak is particularly intresting because it shows OpenAI pivoting to "cognitive density" rather than just scaling up parameters. I've seen similar patterns in enterprise deployments where smaller, more efficient models actually outperform bloated ones on specific tasks. The pruning approach could fundamentaly change how we think about model architecture if the leaks hold true.
