In 86,945 stars, four groups inside the Gaia-Sausage/Enceladus region showed similar magnesium, calcium and titanium, but split in aluminum, carbon-to-nitrogen and age. Their spread fits debris added across multiple accretion episodes.

The signal came from a violently merging galaxy and was boosted by gravitational lensing. MeerKAT caught it while targeting something else, using wide frequency coverage to pick up two cosmic fingerprints in one observation.

Marine sediments off eastern Canada traced the shift during the Younger Dryas. The warming near Nova Scotia appears to have been temporary, lasting only the first few hundred years before colder conditions overran it.

The timeline comes from DNA across 82 living species combined with evidence from 29 fossils. It also resolved where two long-unsampled groups fit in the millipede family tree.

Blood samples were used to track patterns tied to earlier or later death, not single molecules alone. The overlap with human mortality patterns was consistent across multiple published datasets, but the signals do not explain cause on their own.

Silver ions cut DNA but much of it was lost. With PEG-coated nanoparticles, targeted cleavage stayed high at moderate temperatures, and desired fragments remained in solution while unwanted bound pieces were removed.
