American Manufacturing Surges to Four-Year High as Factory Activity Expands

The White House announced on April 22, 2026, that the Institute for Supply Management's key manufacturing index registered its third consecutive month of expansion at its highest reading since 2022. Major companies announced significant U.S. manufacturing investments including U.S. Steel restarting its Gary Tin Mill in Indiana (225 jobs), Apple committing $600 billion over four years, Nvidia pledging $500 billion for AI chip production, and Johnson & Johnson investing $55 billion in new U.S. manufacturing. Foreign pharmaceutical companies AstraZeneca ($50 billion), Bristol Myers Squibb ($40 billion), and GSK ($30 billion) also announced major U.S. manufacturing expansions.

NVIDIA Neural Network Sparsity Patent Granted Apr 21

NVIDIA Corporation received US Patent 12608612B2 on April 21, 2026 for 'Pruning and accelerating neural networks with hierarchical fine-grained structured sparsity.' The patent application (No. 17681967) was filed on February 28, 2022 and contains 15 claims across CPC classifications G06N 3/082, G06N 3/0464, G06N 3/063, G06N 3/084, and G06N 3/09. The technology covers hierarchical structured sparse parameter pruning designed to improve runtime performance and energy efficiency of neural networks by constraining non-zero value distribution according to per-level sparsity degrees at each hierarchy level.
