The brain region that could provide a cognitive ‘reservoir’ in old age

Cerebellum-focused neuroscience coverage that surveys recent studies on age-related changes and their broader implications for thinking later in life.

Key takeaways
  • Cerebellum exhibits uneven ageing, with certain subregions losing tissue faster.
  • Preserved volume in specific cerebellar areas correlates with better cognitive performance in older adults.
  • Regional cerebellar resilience suggests it could act as a cognitive reservoir during ageing.

Scientists say most of what’s in your food is still a mystery

Curious about invisible chemistry in your meals?

Key takeaways
  • Thousands of unlisted chemicals exist in common foods beyond standard nutrients.
  • Researchers call this overlooked fraction 'nutritional dark matter' with unknown health impacts.
  • Understanding these compounds could clarify individual diet responses and disease risk.

Messenger RNA-encoded reporters for monitoring cellular stress and bioenergetics (Nature - Biotechnology)

Messenger RNA-encoded reporters for monitoring cellular stress and bioenergetics

Describes an mRNA delivery workflow enabling transient fluorescent reporters to monitor metabolism and cellular stress across primary and stem cells.

Key takeaways
  • IVT-synthesized reporter mRNAs achieved high transfection efficiencies in primary fibroblasts and iPSCs.
  • Three ratiometric reporters detected subcellular pH, hydrogen peroxide, and ATP levels effectively.
  • MRNA delivery avoided genome integration and bypassed stable cell line generation requirements.
