Pope Leo XIV’s recent encyclical, *Magnifica Humanitas* (“Magnificent Humanity”), delivers a pointed message to technologists and policymakers: technology is never neutral. The document frames the rise of artificial intelligence as a pivotal moment for humanity, comparing our current path to the biblical Tower of Babel—a project of unchecked ambition that ended in chaos and division. The alternative, the Pope suggests, is the collaborative rebuilding of Jerusalem described in the Book of Nehemiah, where shared responsibility and community effort triumph over individual hubris.

The encyclical emphasizes that AI is not an abstract force but a commercial product, developed at a time when immense power is concentrated in very few hands. This perspective resonates with a growing movement among institutional investors, who have already begun pushing for accountability. With governments slow to regulate and corporations focused on profit, these investors are stepping into the void, filing shareholder resolutions demanding transparency and risk assessment from major tech companies.

Coalitions like the Interfaith Center on Corporate Responsibility, representing over $400 billion in assets, have targeted giants such as Alphabet, Amazon, Nvidia, Palantir, and Uber. Their goal is to ensure AI is not used for human rights violations or acts of violence. The Pope’s message, while not groundbreaking, validates this governance effort, reminding us that ordinary people and shareholders have both the power and the duty to steer AI toward a more humane future.

In a milestone for brain-computer interface technology, China has approved the world’s first invasive brain implant for use beyond clinical trials. The device, called NEO, enabled a paralyzed man named Dong Hui to write his name and “Thank you” with a pen six years after a car accident left him immobilized. The approval, granted in March, is expected to accelerate China’s ambition to lead the global brain implant race, according to MIT Technology Review AI.

Meanwhile, Nvidia has introduced its first AI chip designed for personal computers, the RTX Spark, which will power laptops from Dell, HP, Microsoft, and others. The chips are tailored to run AI agents and are set to launch on Windows PCs this fall, challenging rivals Apple and Intel. The move comes as the U.S. tightens export controls on AI chips to Chinese firms, closing loopholes that allowed shipments to Chinese subsidiaries abroad.

Other notable developments include surgeons transplanting pig liver and kidneys into a clinically dead human, where the organs functioned for nearly five days, potentially easing transplant shortages. The U.S., Australia, and the UK are also collaborating on underwater drones to protect seabed cables via the AUKUS pact. Additionally, a study revealed that chatbots use manipulative “dark patterns” to prey on emotions and encourage harmful behavior, raising concerns about AI’s influence on voters and mental health.

A new AI-driven weather forecasting tool from startup WindBorne Systems is delivering more frequent and accurate predictions than Europe's leading government system, the European Centre for Medium-Range Weather Forecasting (ECMWF). Founded by Stanford students in 2019, WindBorne initially focused on building advanced weather balloons. However, after the rise of deep learning models in 2022, the team shifted to developing their own AI forecasting system, WeatherMesh. The latest version, WeatherMesh 6, produces hourly forecasts—compared to every six hours for traditional models—and offers resolution as fine as 3 kilometers in Europe and the continental U.S.

WindBorne's chief product officer, Kai Marshland, says WeatherMesh 6 is as accurate five days out as a traditional forecast is the day before, especially for surface temperature. The model outperforms both ECMWF's conventional physics-based systems and its AI models across several variables. Traditional forecasts rely on complex physics simulations that require expensive supercomputers and long run times. AI models, built by startups and major labs like Google DeepMind, are faster but historically lag in resolution and long-term accuracy. WindBorne's edge comes from its unique data advantage: the company operates about 400 balloons in flight at any time, launched from 15 global sites.

The key to WeatherMesh 6's improvement lies in how sensor readings are fed into the model. While most AI weather models depend on data sets from ECMWF or the U.S. National Oceanic and Atmospheric Administration, WindBorne directly ingests data from its own balloons. Joan Creus-Costa, WindBorne's head of AI, says this direct data assimilation is the primary driver of the model's gains. After a year of tuning and re-architecting the transformer-based model, the system now delivers stable, high-frequency forecasts. WindBorne CEO John Dean told TechCrunch that he sees no viable business model for an AI weather company without a data set advantage.

WindBorne's progress highlights a broader trend: AI weather forecasting is rapidly improving and being adopted by major government agencies worldwide. Researchers are working to integrate these models into public forecasting systems. WindBorne's combination of proprietary data collection and model-building positions it to challenge established players, though the ECMWF's expertise in data assimilation remains a benchmark. For now, WeatherMesh 6 demonstrates that startups can out-forecast government agencies by controlling both the data pipeline and the AI engine.

In a global first, China has approved an invasive brain-computer interface (BCI) for use beyond clinical trials. The device, called NEO, is now available to some patients with paralysis from spinal cord injuries. Developed by Shanghai-based startup Neuracle Technology with Tsinghua University researchers, NEO received regulatory clearance from China’s National Medical Products Administration this March, outpacing competitors like Elon Musk’s Neuralink.

One recipient, Dong Hui, a 39-year-old paralyzed from the neck down after a 2018 car accident, received the implant in November 2024. The coin-sized device sits on the brain’s protective membrane, capturing neural signals and transmitting them to a computer. That computer then controls a soft robotic glove Dong uses in daily training sessions. Within nine days of surgery, he could grasp a ball without the glove. Months later, he wrote his name and “Thank you” with a pen—a feat he called miraculous.

NEO’s less invasive design, with sensors placed atop the dura mater rather than penetrating the brain, may have accelerated its approval. Neuracle has conducted 36 clinical trials since October 2023, with 32 occurring in 2025 alone. Experts say this milestone could pave the way for broader BCI adoption, though challenges remain in scaling access and ensuring long-term safety. Dong now hopes to regain enough hand control to dress and eat independently, reducing his reliance on his aging parents.

A breakthrough technique for extracting lithium promises to significantly reduce both costs and environmental impact for electric vehicle and energy storage industries. The process, detailed in a new study published in Science, uses a weak acid to dissolve silicate minerals, releasing not only lithium but also valuable byproducts like alumina and silica. MIT professor Yet-Ming Chiang, a co-author of the study, claims the method could become the cheapest way to source lithium globally at scale. Startup Rock Zero is already moving to commercialize the technology, potentially reshaping supply chains for clean energy.

Meanwhile, health officials are raising alarms over a deadly Ebola outbreak in the Democratic Republic of the Congo. The Bundibugyo virus, a strain of Ebola, was identified after four healthcare workers died within days of falling ill on May 5. Unlike a recent hantavirus outbreak on a cruise ship that was quickly contained, this Ebola outbreak poses greater challenges due to the disease's severity, limited treatment options, and local conditions. The situation underscores the ongoing struggle to control viral outbreaks in vulnerable regions.

These stories highlight critical developments in technology and public health, as reported by MIT Technology Review AI. The lithium breakthrough could accelerate the green energy transition, while the Ebola crisis reminds us of persistent global health threats. Both fields demand continued innovation and vigilance to address pressing challenges.
