Evidence check: Millions take calcium and vitamin D for stronger bones. A major review finds little benefit
Meta-analysis of nearly 154,000 adults found little to no clinical benefit from calcium and vitamin D supplements for most older adults, supporting cautious re-evaluation of routine use.
Human evidence Randomised human evidence Potentially actionable with caution
Evidence check: New psychedelic-like drugs could treat depression without making you trip
This is an appropriately enthusiastic report of early-stage drug discovery. It references robust lab work and novelty in chemical scaffolds, but there is no clinical, human, or meaningful disease-modifying evidence at this time. Human relevance remains hypothetical.

Evidence check: Poor sleep linked to rising cancer risk in under-50s
The study suggests an association between poor sleep and early-onset cancers, but evidence is observational and confounding factors prevent causal inference.
Observational, not causal Observational human evidence Not clinically actionable
Evidence check: A personalized vaccine for melanoma cut the risk of cancer returning after five years
While initial trial results for the melanoma vaccine are promising, claims outpace the available peer-reviewed evidence and longer-term follow-up.
Early-stage only Limited human evidence Not clinically actionable
Evidence check: Blood and spinal fluid proteins reveal distinct fingerprints of four brain diseases
This is a robust molecular profiling study in humans, but proposed diagnostic and therapeutic applications are not yet validated, making clinical conclusions premature.
