Tuna fishing dates back 44,000 years and billfish 10,000, yet a PNAS review finds heavy offshore fishing mostly began only in the last 200 years.
news Biology Evidence status: Peer reviewed · Lab aquarium study
In aquarium tests, all 5 bleached coral fragments touching a healthy clone recovered; the 5 held a few millimetres apart did not. A small lab study, not a reef fix.
news Biology Evidence status: Peer reviewed; DNA (phylogenomic) study; fossil literature review
DNA from museum owls suggests barn owls reached the Americas through the Caribbean, which later lost six barn owl species, more than any other island region.
news Biology Evidence status: Peer reviewed · Observational (historical records)
A century of records shows most tracked European bee species and about half of hoverflies now occupy fewer places, though most species still persist.
news Biology Evidence status: Peer reviewed; population biobank analysis; no health outcomes assessed
A survey of about 905,000 genomes finds a typical person carries 4.3 to 5.3 million variants and 1 to 3 rare disease-linked ones, mostly as carriers.
news Biology Evidence status: Peer reviewed · Meta-analysis of published fossil records
A Nature Plants study of fossil pollen links most plant turnover of the past 120 million years to two hot spells. How it was done, and what it cannot show.
news Biology Evidence status: Peer reviewed · Single fossil specimen
A 165-million-year-old swimming relative of mammals kept throat bones like ours. What the Nature fossil shows, how, and why it rests on a single skeleton.
news Biology Evidence status: Peer reviewed · Genomics study (embryos and tissues)
A Nature Communications study maps how DNA folds in squid, cuttlefish and octopus: stable domains, shifting loops, and one switch deletion that shrank brains.
news Biology Evidence status: Peer reviewed; observational study of pet dogs
A Science study of 894 pet dogs links faster DNA-methylation ageing to large size and male sex. What it found, how, and why it doesn't yet prove a cause.
