External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird

open access: yesIbis, Volume 168, Issue 4, Page 1696-1703, October 2026.
In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes.

Waste‐Derived Fine‐Milled Bone Char for Apparent Cr (VI) Removal From Water and Preliminary Asphalt‐Compatible Processing of the Recovered Residue

open access: yesWater Environment Research, Volume 98, Issue 9, September 2026.
Waste‐derived ultrafine bone char removed Cr (VI) from acidic synthetic water, and the recovered Cr‐loaded solid was incorporated into asphalt‐compatible binder and mortar without major rheological disruption. The pathway links contaminant capture with preliminary spent adsorbent management, but leaching, chromium speciation, aging, and real‐wastewater
