Number’s up: Calculators hold out against AI

In July, AI models made by Google, OpenAI and DeepSeek reached gold-level scores at the annual International Mathematical Olympiad

The humble pocket calculator may not be able to keep up with the mathematical capabilities of new technology, but it will never hallucinate.

The device’s enduring reliability equates to millions of sales each year for Japan’s Casio, which is even eyeing expansion in certain regions.

Despite lightning-speed advances in artificial intelligence, chatbots still sometimes stumble on basic addition.

In contrast, “calculators always give the correct answer,” Casio executive Tomoaki Sato told AFP.

But he conceded that calculators could one day go the way of the abacus.

“It’s undeniable that the market for personal calculators used in business is on a...

As artificial intelligence (AI) and smart gadgets become more common, our need for reliable power sources grows. Renewable energy options like solar and wind are great, but they depend on specific conditions. A research team led by Professor Dong-Myeong Shin from the Department of Mechanical Engineering at the University of Hong Kong (HKU) has developed a novel moisture-activated electricity generator (MEG) that offers a fresh, eco-friendly way to generate electricity—just from moisture in the air.

Their findings have been published in the journal Advanced Functional Materials in an article titled “Long-Lasting Moisture Energy Scavenging in Dry Ambient Air Empowered by a Salt Concentration-Gradient Cationi...

Rebalancing the Gut: How AI Solved a 25-Year Crohn’s Disease Mystery

Electron micrographs show how macrophages expressing girdin neutralize pathogens by fusing phagosomes (P) with the cell’s lysosomes (L) to form phagolysosomes (PL), compartments where pathogens and cellular debris are broken down (left). This process is crucial for maintaining cellular homeostasis. In the absence of girdin, this fusion fails, allowing pathogens to evade degradation and escape neutralization (right).

AI uncovers how a severed bond between two gut proteins sparks Crohn’s disease, and how restoring it could heal inflammation. UC San Diego researchers combined artificial intelligence with molecular biology to unravel how immune cells in the gut decide between inflammation and healing, a process gone awry in Crohn’s disease...

Over the past decades, electronics engineers have developed a wide range of memory devices that can safely and efficiently store increasing amounts of data. However, the different types of devices developed to date come with their own trade-offs, which pose limits on their overall performance and restrict their possible applications.

Researchers at Université Grenoble Alpes (CEA-Leti, CEA List), Université de Bordeaux (CNRS) and Université Paris-Saclay (CNRS) recently developed a new memory device that combines two complementary components typically used individually, known as memristors and ferroelectric capacitors (FeCAPs)...
