An AI startup, Subquadratic, claims to have solved a decade-long mathematical bottleneck in large language models, reducing computational needs and energy use. Brain-computer interface (BCI) trials are expanding, with China approving the first BCI for medical use and a case study highlighting its impact on an ALS patient.

Casey Harrell, a man with ALS, uses a brain-computer interface (BCI) to communicate, work, and engage online. The University of California, Davis team has improved the device's accuracy and added features like privacy mode. China recently approved a BCI for medical use, and trials are expanding globally.

A brain-computer interface (BCI) system developed by the University of California, Davis, and the BrainGate coalition has enabled Casey Harrell, an ALS patient, to communicate and work full-time since 2023. The system translates brain activity into speech with high accuracy, allowing Harrell to engage in daily conversations and professional tasks despite paralysis.

Casey Harrell, an ALS patient, is the first 'power user' of a brain-computer interface (BCI) that enables speech and web navigation. South Koreans exhibit strong optimism about AI, with 50% of Americans expressing concern compared to 16% in South Korea, reflecting the country's tech-driven modernization ethos.

Casey Harrell, a man with ALS, has used a brain-computer interface (BCI) for over 3,800 hours to communicate, surf the web, and work independently. The implant, developed by a UC Davis research team, decodes neural activity into speech and was detailed in a study published in Nature Medicine.
