Google’s new environmental report directly ties AI growth to infrastructure pressure, stating that AI infrastructure is accelerating faster than grid decarbonization. The company reports a 37% annual increase in electricity demand, while also claiming a 2% reduction in operational emissions, 12 GW of new clean-energy agreements, more than 58 million tCO₂e avoided through efficiency and procurement, and 41 million tCO₂e of enabled emissions reductions from AI/product solutions.
Google’s new environmental report directly ties AI growth to infrastructure pressure, stating that AI infrastructure is accelerating faster than grid decarbonization.
This is useful because it captures the tension between AI’s claimed climate-enabling benefits and the physical energy demands of scaling data centers.

A review of evidence across cognitive science, education, medicine, and human-factors research finds that fully offloading mental work to AI can weaken the acquisition and retention of the specific skills people stop practicing. The authors distinguish that evidence from broader claims about declining intelligence: effects on foundational abilities such as attention and working memory remain uncertain, while AI used as a collaborator, tutor, or source of feedback can preserve or improve learning.
The NUS/Harbin-led team identifies a domain-specific form of generative-AI hallucination: molecular candidates can receive strong predicted binding scores while violating basic chemistry or producing physically impossible atomic arrangements. Its DrugRPG framework incorporates chemical-foundation-model priors and differentiable physical constraints during molecule generation, reducing severe steric clashes by 65.4% relative to the reported state-of-the-art baseline and increasing by 28.6% the share of generated candidates meeting combined potency, stability, and synthetic-feasibility criteria.
Reviewing 72 studies of reinforcement-learning systems for sepsis treatment, the authors found that every study was retrospective, 58 studies—80.6%—relied on the same MIMIC critical-care database, and only 10 used private datasets. Although many papers claimed that AI-derived treatment policies outperformed clinicians, variation in how patient states, treatment actions, rewards, and counterfactual outcomes were defined made those comparisons difficult to validate.
