Tak@Here are today's top AI & Tech news picks, curated with professional analysis.
Anthropic considered paying $7 billion for a startup that doesn't even sell a single chip yet. What it wanted to buy wasn't in factories
Expert Analysis
Anthropic, the company behind Claude, explored acquiring the startup MatX for approximately $7 billion to reduce its dependence on external AI infrastructure. The goal was not merely to buy chips, but to gain the years of time and expertise required to develop its own AI accelerators.
MatX was founded by former Google engineers, Reiner Pope and Mike Gunter, who were instrumental in developing Google's TPUs. Their combined expertise in designing AI accelerators, including compilers, interconnects, memory systems, and model execution tools, is considered highly valuable.
Although the acquisition did not materialize, Anthropic has hired Amir Salek, founder of Google's custom chip program, and is building an internal team to co-design its AI models and future hardware. This strategic move aims to reduce reliance on external providers like Nvidia, Google, and Amazon, leading to potential cost savings and optimization.
- Key Takeaway: Anthropic's pursuit of custom AI chips highlights the industry's drive for vertical integration and reduced dependency on external hardware providers to optimize costs and performance for large language models.

Soil microplastics have a problem: a filter can't go looking for them. That's why magnetic microrobots have been created that can reach them, and have already removed up to 81% in the laboratory
Expert Analysis
A team of researchers from the Technical University of Ostrava in the Czech Republic has developed magnetic microrobots designed to remove microplastics from soil and water. These robots are composed of a two-dimensional material called MXene and nickel nanoparticles, allowing them to move via external magnetic fields and adsorb pollutants.
Unlike conventional static filters, these microrobots can actively move towards contaminants, proving effective even within the complex structures of soil. In laboratory tests, they removed approximately 94% of polystyrene and 89.2% of PET from water, and 80.6% and 72.2% respectively from a soil model.
This technology inverts the traditional approach: instead of waiting for microplastics to reach a filter, the filter itself goes to find the contaminants. Future challenges include validating its effectiveness in more complex real-world environmental conditions and ensuring the complete recovery of the robots after use.
- Key Takeaway: Magnetic microrobots offer a promising, active solution for microplastic removal in complex environments like soil, demonstrating higher efficiency than passive filtration by actively seeking out contaminants.

China has covered 1,817 hectares of the Gobi Desert with a 1 GW solar power plant. The key is not the panels: 260,000 mirrors heat salt to 550 ºC to continue producing at night
Expert Analysis
China has constructed a 1 GW hybrid solar power plant spanning 1,817 hectares in the Gobi Desert. This facility integrates 900 MW of photovoltaic (PV) solar energy with 100 MW of concentrated solar thermal power (CSP).
The innovative aspect of this power plant lies in its CSP section. Approximately 260,000 high-precision reflectors concentrate solar radiation to heat molten salts to about 550 ºC, storing thermal energy. This stored heat enables the plant to generate electricity stably for up to eight hours during the night or adverse weather conditions.
This system addresses the primary challenge of solar power—its intermittency—by ensuring a stable supply to the grid even after sunset. Built by China Three Gorges Renewables, this project demonstrates the critical role large-scale thermal storage technology plays in enhancing the reliability of renewable energy.
- Key Takeaway: China's 1 GW hybrid solar plant in the Gobi Desert showcases a significant advancement in renewable energy by using concentrated solar thermal power with molten salt storage to provide continuous electricity generation, even at night.
