A recent MIT EEG study reported by Time found that students using ChatGPT showed significantly lower brain engagement during essay writing—exhibiting reduced neural, linguistic, and behavioral effort compared to peers who researched or used Google. Over time, they “got lazier with each subsequent essay,” frequently resorting to copy-and-paste, and underperformed overall.

A 2025 Microsoft study revealed that its AI system, MAI-DxO, correctly diagnosed 85% of complex medical cases—four times more accurately than experienced physicians.

A new MIT Media Lab study (2025) found that using ChatGPT for essay tasks led to significantly weaker brain activity compared to writing without AI or using search engines, as shown by EEG scans. The ChatGPT group not only struggled to recall what they wrote, but also produced more formulaic text and felt less ownership over their work.

A 2025 study backed by the National Institute for Health and Care Research found that a new at-home foot scanner from Heartfelt Technologies could detect fluid build-up—an early sign of heart failure—an average of 13 days before a patient needed hospital care. It accurately predicted 5 of 6 hospitalizations.
