A new study of 2,000 U.S. adults shows dark web users report much higher rates of depression, paranoia, suicidal thoughts, self-injury and digital self-harm than surface web users. People with suicidal thoughts were nearly three times more likely to use the dark web, while those engaging in self-injury or digital self-harm were up to five and 19 times more likely, respectively. Researchers suggest dark web use may reflect underlying mental health struggles and urge professionals to reach vulnerable users in these hidden spaces.

With a new $2.3 million, four-year grant from the National Institute of Biomedical Imaging and Bioengineering, part of the National Institutes of Health, researchers at Virginia Tech’s Fralin Biomedical Research Institute at VTC are developing tools and techniques for gathering high-quality brain function data during during parent-child interactions.

Kyoto, Japan -- Shisei Tei claims he is clumsy with technology and doesn't even own a smartphone, yet he has found himself thinking a lot about what we call generative AI.

Tei is cautious rather than optimistic about AI. As a researcher, he uses it to help with analyzing psychiatric data, and outside work it helps him plan personalized hikes. But Tei is concerned that AI will change how we think about death, which he discusses in a chapter he wrote for the book SecondDeath: Experiences of Death Across Technologies.

"Today, I often see how AI reframes grief and remembrance," says Tei. Though he thinks mental health chatbots have the potential to lower barriers to care, maladaptive use of chatbots that reconstruct deceased individuals can distort our perceptions of death and existence.

A new large-scale study reveals that uncertainty in climate policy (CPU) is a significant driver for improving corporate Environmental, Social, and Governance (ESG) performance. Analysing data from 4,490 Chinese listed companies (2011-2022), researchers found a strong positive correlation between CPU and ESG scores. The primary motivation is risk mitigation: companies facing higher systemic risk use enhanced ESG performance as a strategic shield. The effect is most pronounced in non-state-owned enterprises, heavy-polluting industries, and highly competitive markets. The findings provide crucial insights for businesses strengthening sustainability strategies and for policymakers aiming to foster resilient, low-carbon economic growth.
