AI Capex Slows as Sodium-Ion Batteries Challenge Lithium

AI Investment Boom May Slow, While Scientists Make Battery Breakthroughs

A surge in capital expenditures (capex) on artificial intelligence (AI) that has boosted tech stocks may be losing momentum, analysts warned, even as companies like Meta and Tesla pledged to continue investing heavily in the technology. This development coincided with breakthroughs in battery technology, as scientists announced advancements in sodium-ion batteries as a potentially safer and faster-charging alternative to lithium-ion.

Tech stock futures initially showed promise, with Nasdaq 100 contracts up 0.22% and SP 500 futures up 0.19% prior to the opening bell in New York, according to Fortune. However, analysts cautioned that the pace of capex growth related to AI was expected to slow in the coming years. Meta, Tesla, and Microsoft all saw stock fluctuations based on their earnings calls, where each company discussed their AI spending plans. Meta's capex could reach $135 billion this year, according to Fortune.

In other tech news, researchers at the Tokyo University of Science reported a breakthrough in sodium-ion (Na-ion) batteries, according to Hacker News. These batteries could offer faster charging speeds, higher energy density, and improved safety compared to conventional lithium-ion (Li-ion) batteries. The scientists used a new carbon-based electrolyte to enhance Na-ion energy density and charge speeds. Sodium-ion batteries are being investigated as an alternative to lithium-ion batteries due to their potential advantages.

Meanwhile, in the realm of energy infrastructure, the eastern half of the US recently weathered a significant snowstorm, according to MIT Technology Review. The power grid largely maintained functionality despite freezing temperatures and increased demand. However, there were signs of strain, particularly for fossil-fuel plants. One analysis indicated that PJM, the nation's largest grid operator, experienced unplanned outages in plants that run on natural gas and coal. These facilities historically face challenges in extreme winter weather. The article also questioned what lessons can be learned from the storm, and how the grid can be strengthened to cope with extreme weather.

Airtable also announced its entry into the AI agent space with Superagent, a standalone research agent that deploys teams of specialized AI agents working in parallel to complete research tasks, according to VentureBeat. Airtable is applying its data-first design philosophy to AI agents. According to Airtable co-founder Howie Liu, the technical innovation lies in how Superagent's orchestrator maintains context, creating "a coherent journey" where the orchestrator makes all decisions along the way.

In space news, astronomers may have solved a mystery surrounding "Little Red Dots" observed by the James Webb Space Telescope, according to Ars Technica. A new study published in Nature suggests that young supermassive black holes may go through a cocoon phase, growing while surrounded by high-density gas they feed on. These gaseous cocoons are likely what the telescopes are observing.

History Rewrites Itself: Tsunamis, Troy, and Revolutionary Revelations!

A recent review of historical evidence and eyewitness accounts from multiple sources suggests the devastating flood of January 30, 1607, in the Bristol Channel and Severn Estuary, which killed up to 2,000 people, may not have been solely caused by a storm, prompting researchers to consider other potential explanations like a tsunami. The flood, which inundated coastal communities across south Wales, Somerset, Gloucestershire, and Devon, was described as unlike typical storms or high tides, leading to the re-examination of its cause.
