Learners using AI tools for autonomous out-of-class language practice showed improved speaking proficiency and reduced communication anxiety.

This October 2025 scoping review synthesized 65 empirical studies up to mid-April 2025 on AI-mediated informal language learning, defined as self-directed out-of-class L2 learning with AI tools. It found a nascent, fast-growing field after ChatGPT's release, concentrated in East Asia and dominated by cross-sectional designs with limited theory.

AI applications in healthcare could expand access and improve disease surveillance and health system planning for marginalised populations in Sub-Saharan Africa.

This scoping review mapped evidence published up to March 2026 on AI in healthcare in Sub-Saharan Africa, focusing on marginalised populations. Searching four databases and grey literature, the authors included 23 sources and synthesised them thematically.

AI software-as-a-medical-device platforms cleared since 2019 that estimate sleep parameters improve accessibility to obstructive sleep apnea diagnosis for patients unable or unwilling to undergo in-laboratory polysomnography.

By August 2026, peer-reviewed guidance for neurologists described a shift in obstructive sleep apnea diagnosis from in-laboratory polysomnography alone to home testing augmented by wearables, nearables, and FDA-cleared software-as-a-medical-device platforms that leverage artificial intelligence and multisignal integration to estimate sleep parameters. The article framed these tools as improving accessibility for patients unable or unwilling to undergo lab studies.

A random forest model trained on 16S rRNA microbial community data from a field mesocosm predicted antifouling paint particle presence in sediment, with perfect detection of presence in test set and correct classification of all uncontaminated and 3 of 5 contaminated real-world Baltic Sea sites.

On 2026-08-03, a peer-reviewed study reported a random forest model trained on 16S rRNA gene sequencing from a field mesocosm to predict antifouling paint particle contamination in sediment. In lab incubation tests it identified 100% of presence samples and 83.3% of absence samples, and when applied to 14 Baltic Sea and Warnow estuary sites it correctly labeled all uncontaminated sites and three of five contaminated sites.

AI struggles to generate novel hypotheses and apply creative, contextual reasoning, limiting its utility in rare disease diagnosis and complex uncertain scenarios.

A 2026 narrative review and conceptual analysis in Diagnosis synthesized literature on noise in medical decision-making, AI applications in healthcare, and clinical reasoning, reviewing case studies in radiology and pathology and empirical data on AI performance.

Deep neural networks are unable to learn multiple tasks sequentially, suffering catastrophic forgetting when trained on new tasks.

On March 14, 2017, authors in PNAS described a method to overcome catastrophic forgetting in deep neural networks. They noted that while deep networks were the most successful technique for translation, image classification and generation, they could not learn multiple tasks sequentially. Their solution protects weights important for previous tasks, inspired by synaptic consolidation.

The same survey found overreliance on labels, making participants more susceptible to false claims with human-made images and more hesitant to believe true claims illustrated with labeled AI-generated images.

Researchers studied whether legally mandated disclosure labels help users avoid deception from AI-generated images. After five focus groups, they surveyed 1,354 participants on how labels changed their judgments of true and false claims illustrated with different image types.

Generative AI increases the scale and speed of Trust and Safety attacks and lowers barriers to creating sophisticated propaganda and deepfakes.

On April 13, 2026, a peer-reviewed CHI paper reported a qualitative study of 43 Trust & Safety experts across child safety, election integrity, hate and harassment, scams, and violent extremism. It found generative AI both expands attacker capabilities and offers new defensive tools for detection and mitigation.
