The reliability of subjective reports of sleep duration and quality: Insights from in-home electroencephalography

International Institute for Integrative Sleep Medicine, University of Tsukuba
Peer-Reviewed Publication

Researchers from University of Tsukuba have identified significant discrepancies between subjective and objective assessments of sleep. The study revealed that 66% of individuals who perceived their sleep as poor showed no objective sleep problems, while 45% of those who considered their sleep adequate were objectively sleep-deprived. These findings underscore the inadequacy of subjective sleep assessments for early diagnosis and effective intervention of sleep disorders, highlighting the critical role of objective tools such as sleep electroencephalography.

Mapping gene regulation

Institute for the Advanced Study of Human Biology (ASHBi), Kyoto University
Peer-Reviewed Publication

An international team of researchers has taken an important step toward understanding how gene expression is controlled across the human genome. A new study has comprehensively analyzed “cis-regulatory elements” (CREs), which are the DNA sequences that regulate gene transcription. This work sheds light on how these elements contribute to cell-specific gene expression and how mutations within them may influence health and disease.
