Dual pKa Lipid Nanoparticles for Lung‐tropic mRNA Delivery and pH‐Programmed Endosomal Escape

Advanced Science, EarlyView.
Lipid nanoparticles’ bottleneck lies in low endosomal escape efficiency and liver‐dominant delivery after intravenous administration. To overcome these limitations, we present a stepwise pH‐programmed lipid nanoparticle system enabled by our newly synthesized ionizable lipid.

Butterflies Across the Globe: A Synthesis of the Current Status and Characteristics of Monarch (Danaus plexippus) Populations Worldwide

Frontiers in Ecology and Evolution, 2019
Recent declines in the migratory North American populations of monarchs (Danaus plexippus) have necessitated efforts to evaluate the current status of the species, including worldwide populations.

Bone Marrow Macrophage STING Signaling is a Direct Nexus Linking Marrow Adipose Expansion to NAD+ Depletion and Osteogenic Decline in Skeletal Aging

Advanced Science, EarlyView.
This study reveals that during skeletal aging, bone marrow adipocyte‐derived sDPP4 primes STING signaling in macrophages. In combination with mitochondrial DNA, this signaling activates CD38 and depletes local NAD+/NMN, thereby impairing osteogenesis.

Who cares about monarch butterflies? Comparing US State Wildlife Action Plans 2015–2025

Conservation Letters, 2023
In 2023, the International Union for Conservation of Nature listed the iconic North American monarch butterfly (Danaus plexippus) as Vulnerable due to population declines. Yet, in the United States, there are no national laws protecting monarchs. In 2020,

Transposable Element Dynamics Drive the Genomic Evolution and Phenotypic Diversification of Allotetraploid Common Carp

Advanced Science, EarlyView.
By integrating 516 whole‐genome resequencing datasets and 236 transcriptomes of allotetraploid common carp, this study establishes the first population‐scale atlas of transposable element (TE) variation in teleost species. TE bursts, relaxed purifying selection, and lineage‐specific loss of ancient insertions shape genome evolution and phenotypic ...

Design Implications for Surveys to Monitor Monarch Butterfly Population Trends

Frontiers in Ecology and Evolution, 2019
The Iowa Multiple Species Inventory and Monitoring (MSIM) Program includes a protocol for monitoring butterfly density on conservation lands using transects. Most data are collected from sites chosen randomly; additional sites are chosen non-randomly for

Aphid infestations reduce monarch butterfly colonization, herbivory, and growth on ornamental milkweed.

PLoS ONE, 2023
Anthropogenic disturbance is driving global biodiversity loss, including the monarch butterfly (Danaus plexippus), a dietary specialist of milkweed. In response, ornamental milkweed plantings are increasingly common in urbanized landscapes, and recent ...
