A Potential Dynamical Origin of the Galactic Disk Warp: The Gaia–Sausage–Enceladus Major Merger

open access: yesThe Astrophysical Journal
Previous studies have revealed that the Galactic warp is a long-lived, nonsteady, and asymmetric structure. There is a need for a model that accounts for the warp’s long-term evolution. Given that this structure has persisted for over 5 Gyr, its timeline

Calcium retinoate nanoparticle mediated microglial polarization to regulate inflammatory microenvironment for therapy of neuroinflammatory disease

open access: yesBMEMat, EarlyView.
A nano‐drug based on retinoic acid and calcium is developed, which can be rapily endocytosed by microglia and decomposed into small molecule/ion storms in lysosomes. This nano‐drug regulates microglial phenotype switching from M1 to M2 while indirectly guiding neuronal differentiation of endogenous neural stem cells, thereby ameliorating ...

A Low-mass Model of the Milky Way: The Disk Warp Resulting from a Galaxy Merger

open access: yesThe Astrophysical Journal
Previous studies have shown that disk warps can result from galaxy mergers. Recent research indicates a noticeable decline in the rotation curve (RC) of the Milky Way, suggesting the need for a new low-mass model to describe its dynamical features.

An automated microfluidic biosensor with bispecific rabbit monoclonal antibody and nanozyme‐bioenzyme composite for dual antibiotic detection

open access: yesBMEMat, EarlyView.
This study introduces an automated microfluidic biosensor for simultaneous detection of florfenicol and thiamphenicol in environmental water. By integrating a phage‐screened bispecific rabbit monoclonal antibody with a nanozyme‐bioenzyme composite, the system achieves sensitive dual‐antibiotic detection. Coupled with smartphone‐based sensing, it offers

Theranostic nanoplatform for high‐performance dual‐modal magnetic resonance imaging‐guided therapy of orthotopic hepatocellular carcinoma

open access: yesBMEMat, EarlyView.
This article introduces a biomimetic Mn‐doped polydopamine nanoplatform (HAMM NPs) coated with cancer cell membranes. It enables targeted hepatocellular carcinoma theranostics via T1/T2 dual‐mode magnetic resonance imaging and tumor microenvironment‐triggered sonodynamic therapy/chemodynamic therapy, achieving potent antitumor efficacy in subcutaneous ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Figuring Out Gas and Galaxies in Enzo (FOGGIE). IX. The Angular Momentum Evolution of Milky Way–like Galaxies and Their Circumgalactic Gas

open access: yesThe Astrophysical Journal
We investigate the coevolution of the angular momentum of Milky Way–like galaxies, their circumgalactic gas, and their dark matter halos using zoom-in simulations from the Figuring Out Gas and Galaxies in Enzo suite.

Dark matter decay in the Milky Way halo

open access: yes
Dark matter may be detected in X-ray decay, including from the decay of the dark matter particles that make up the Milky Way (MW) halo. We use a range of density profiles to compute X-ray line intensity profiles, with a focus on the resonantly produced sterile neutrino dark matter candidate.

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.
