Researchers reach superconductivity at ambient pressure, record high temperature — milestone of -122°C reached by using pressure quenching, still 140 degrees off room temperature target

Researchers from the University of Houston managed to increase the critical temperature for superconductivity by about 18 K at ambient pressure, but at −122°C, they are still 140°C away from the target.

Samsung commits historic $74 billion for AI chips, Texas factory

Samsung announced an investment of over 110 trillion won, roughly $74 billion in AI chips, Texas semiconductor factory expansion, and R&D in 2026.

That’s meant to secure leadership in the AI semiconductor era, according to the company’s corporate value enhancement strategy disclosed on March 19th.

Samsung thinks this is the moment to go all in on AI chips. The Taylor, Texas Foundry is expected to reach mass production sometime in 2027, which means most of the equipment installs and process work have to be wrapped up this year if that timeline stays remotely intact.

On the memory side, HBM4 is now in mass production, delivering speeds of 11.7 gigabits per second that exceed the industry standard of 8GB, while the company’s already pushing HBM4E and HBM5 development simultaneously.

Samsung posted 20 trillion won in operating profit in the fourth quarter of last year, and brokerages have forecast annual operating profit exceeding 130 trillion won this year, so this $74 billion isn’t a gamble.

It’s Samsung doubling down at the exact moment the memory supercycle and the foundry recovery overlap. The company’s betting it can convert HBM momentum and the Taylor ramp into sustained dominance before the window closes.

Last year Samsung spent 90 trillion won total, which was already a company record. This year’s number shatters that by more than 20 trillion won. It’s also the fattest single year inside the company’s already massive five year, 450 trillion won investment roadmap.

Meta's new MTIA lineup joins hyperscalers' unified push for dedicated inferencing chips — companies diversify AI chips in effort to diversify from sole reliance on Nvidia

As Meta introduces its lineup of new AI chips, the company joins other tech giants in diversifying the AI accelerators used for specific workloads, and says that mainstream GPUs built for large-scale pre-training are less cost-effective for inference workloads.

Rimal Semiconductors raises bridge round from Keheilan

Rimal Semiconductors, a Saudi-based chip design startup, has raised a bridge funding round from Keheilan Asset Management alongside an undisclosed regional investor, bolstering its ambitions to expand its role in the global semiconductor ecosystem.

The new capital will advance Rimal’s plan to scale as a fabless semiconductor company—focusing on chip design while relying on international foundries for manufacturing. The startup already works with partners in Taiwan, South Korea, and China, and is now in talks with US foundries to further broaden its production footprint.

Rimal frames this distributed model as a strategic response to the increasingly fragmented semiconductor landscape, where US–China tensions continue to reshape supply chains and limit market access for many firms.

By keeping its intellectual property under Saudi ownership while diversifying manufacturing across multiple geographies, the company aims to ensure its chip designs can reach global customers regardless of where fabrication takes place.

The startup is also close to finalizing a distribution agreement with a regional partner covering Turkey, Egypt, Morocco, Tunisia, and the UAE. The deal includes on‑the‑ground engineering teams to support clients in each market.

Rimal currently has six contracts in advanced stages, including one with a major Egyptian conglomerate. The projects span defence technologies, power grid systems, and data‑centre infrastructure—sectors where demand for specialized semiconductor solutions continues to accelerate.
