Africa: Better roads promote greater dietary diversity

A new study suggests that better access to regional markets is more important than farmers growing a diverse range of crops on their own smallholdings. Markets increase the variety of foods available locally, benefiting the population as a whole.

Update: T cells may offer some protection in an H5N1 ‘spillover’ scenario

A new study by La Jolla Institute for Immunology researchers suggests that many people may already have immune cells on standby to combat the H5N1 virus. The study found similarities between H5N1 and seasonal influenza viruses, allowing scientists to predict cross-reactive T cell responses that could help decrease disease severity.

Pupil size in sleep reveals how memories are sorted, preserved

A study published in Nature found that new memories are replayed and consolidated when the pupil contracts during non-REM sleep, while older memories are replayed when the pupil dilates. This micro-structure separates new learning from old knowledge, preventing 'catastrophic forgetting'.
