WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record compiled from open scholarly databases; the abstract is shown in full only where the paper is openly licensed, otherwise a short excerpt under fair use. Classifications are automated and approximate.

Ancient DNA indicates a century of overhunting did not reduce genetic diversity in Pacific Walruses (Odobenus rosmarus divergens)

Kendall K. Mills, Kyndall P. B. Hildebrandt, Kathryn M. Everson et al. · 2024 · Scientific Reports

Abstract Pacific Walruses ( Odobenus rosmarus divergens [Illiger 1815]) are gregarious marine mammals considered to be sentinels of the Arctic because of their dependence on sea ice for feeding, molting, and parturition. Like many other…

Failing to replicate predicts citation declines in psychology

Cory J. Clark, Paul Connor, Calvin Isch · 2023 · Proceedings of the National Academy of Sciences

With a sample of 228 psychology papers that failed to replicate, we tested whether the trajectory of citation patterns changes following the publication of a failure to replicate. Across models, we found consistent evidence that failing to…

Failed supernova remnants

Daichi Tsuna · 2021 · Publications of the Astronomical Society of Japan

Abstract In a failed supernova, partial ejection of the progenitor’s outer envelope can occur due to weakening of the core’s gravity by neutrino emission in the protoneutron star phase. We consider emission when this ejecta sweeps up the…
