Marking World AIDS Day on 1 December, Eurosurveillance publishes an article that brings together evidence on HIV seroprevalence in five population groups affected by HIV in the countries of the European Union and European Economic Area (EU/EEA): men who have sex with men (MSM), people who inject drugs (PWID), people in prison, sex workers and transgender people
The Life-Saving Lullabies Project is being showcased around the world at various international conferences and will feature in a forthcoming report, commissioned for the World Health Organisation, as an example of how arts-based practices can support relational community engagement processes in lower and middle-income countries.

Researchers from UC Riverside describe a revolutionary imaging technology that compresses lamp light into a nanometer-sized spot. It holds that light at the end of a silver nanowire like a Hogwarts student practicing the “Lumos” spell, and uses it to reveal previously invisible details, including colors, in nanomaterials such as carbon nanotubes.

Exploring the mechanisms involved in sleep-dependent memory storage, a team of University of Michigan (U-M) cellular biologists found that RNAs associated with an understudied cell compartment in hippocampal neurons vary greatly between sleeping and sleep-deprived mice after learning. Sara Aton, Associate Professor in the Department of Molecular, Cellular, and Developmental Biology, and James Delorme, a recent U-M neuroscience graduate student, hypothesized that both a learning event and subsequent sleep (or sleep loss) would impact mRNA translation. Most prior work on the effects of sleep on mRNAs have focused on transcripts in the neuronal cytosol. However, Drs. Aton and Delorme found that after learning, major changes in RNAs are instead present —almost exclusively— on ribosomes associated with neuronal cell membranes. These results have been published in the Proceedings of the National Academy of Sciences, in November 30, 2021.
