Strong Proton‐Phonon Coupling Drives Fast Ion Transport in Perovskites

Advanced Science, EarlyView.
Experimental and computational phonon analysis of ABO3‐type proton conductor BaSnO3 shows that substitution on the B‐site with yttrium forms an imaginary phonon mode which is instrumental for the function as proton conductor. This overcompensates the adverse proton trapping effect of the yttrium.

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

Advanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

Advanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Remote Modulation of Single‐Atom Catalyst Boosts High‐Valent Cobalt–Oxo Species Generation for Water Purification and Detoxification

Advanced Science, EarlyView.
This study develops a phosphorus‐doped cobalt single‐atom catalyst that enhances high‐valent cobalt–oxo species generation for water purification. This atomic‐level tuning boosts the catalyst's activity by 3.5 times, enabling efficient pollutant degradation. A continuous‐flow reactor achieves high, long‐term removal efficiency, producing water with low

Sources of Holocene variability of oxygen isotopes in paleoclimate archives [PDF]

Climate of the Past, 2009
Variability in water isotopes has been captured in numerous archives and used to infer past climate changes. Here we examine water isotope variability over the course of the Holocene using the water-isotope enabled, coupled atmosphere-ocean general ...

Preliminary use of oxygen stable isotopes and the 1983 El Niño to assess the accuracy of aging black rockfish (Sebastes melanops) [PDF]

, 2005
Black rockfish (Sebastes melanops) range from California to Alaska and are found in both nearshore and shallow continental shelf waters (Love et al., 2002). Juveniles and subadults inhabit shallow water, moving deeper as they grow. Generally, adults are
