The Slow Brightening of WNTR23bzdiq/WTP19aalzlk: Possible Onset of Common Envelope Evolution in an Asymptotic Giant Branch Star?

The Astrophysical Journal
We present WNTR23bzdiq/WTP19aalzlk, a slow eruption of an early-asymptotic giant branch (AGB) star in M31 identified by the Wide-field Infrared Transient Explorer near-infrared (NIR) and the NEOWISE mid-infrared (MIR) surveyors.

AlphaFold2‐Guided Cyclic Peptide Stabilizer Design to Target Protein–Protein Interactions

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The control and modulation of protein–protein interactions (PPIs) is of central importance for the majority of biological processes and most biomedical applications. Stabilization of PPIs, besides inhibition, is of growing pharmaceutical interest.

Helium-burning Blue Large-amplitude Pulsators: A Population Study with BPASS

The Astrophysical Journal
Blue large-amplitude pulsators (BLAPs) are a class of radially pulsating stars with effective temperatures ranging from 20,000 to 35,000 K and pulsation periods between 7 and 75 minutes.

Climate change‐driven expansion of goosegrass highlights risks to global food production

Pest Management Science, EarlyView.
Climate change is expanding the climatic suitability of Eleusine indica into temperate agricultural regions, increasing its overlap with major soybean and maize production areas. These findings highlight a growing global threat to food security and the need for proactive weed management strategies.

Identifying Thorne–Żytkow Objects through Neutrinos

The Astrophysical Journal Letters
Thorne–Żytkow objects (T $\dot{{\rm{Z}}}$ Os) have been predicted to form when a neutron star is engulfed by a diffuse, convective giant envelope. Accretion onto a neutron star at a rate that is larger than 10 ^−4 M _⊙ yr ^−1 is expected to lead to ...

Dynamics and model representation of two contrasting extreme precipitation events in the Sahel

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Hovmöller diagrams of the two investigated extreme precipitation events in Mali are shown for (i) IMERG observations, and ICOsahedral Nonhydrostatic model (ICON) runs with parameterization of explicit convection (ii) enabled and (iii) disabled. This work highlights that the commonly perceived benefit of using explicit convection in a state‐of‐the‐art ...

Local regulatory anticipation and GHG emissions

Strategic Management Journal, EarlyView.
Abstract Research Summary Regulatory anticipation is a nonmarket response whereby firms, foreseeing future penalties, adjust their behavior when peers are targeted by regulators. Prior research defines peers using broad jurisdictional boundaries. Instead, I argue that regulatory anticipation may emerge locally, driven by two channels: proximity to peer

Double White Dwarf Binaries in SDSS-V DR19: The Discovery of a Rare DA+DQ White Dwarf Binary with a 31 hr Orbital Period

The Astrophysical Journal
Binaries of two white dwarfs (WDs) are an important class of astrophysical objects that help us reconstruct the complex processes involved in stellar evolution and are theorized to lead to Type Ia supernovae.

Disc‐Toroid Hybrid Lipid Nanoparticles for Efficient Drug Encapsulation and Subcutaneous Delivery

Small, EarlyView.
This study demonstrates sub‐50 nm solid‐lipid nanoparticles with long‐term stability, high drug loading, and strong tissue compatibility. Disc‐toroid morphology is confirmed and may play a role in cellular interactions, while low cytotoxicity and minimal systemic permeation confirm depot‐like behavior. These nanoparticles represent a versatile platform
