Advanced Science, EarlyView.We developed a pH responsive theranostic serum albumin hydrogel named BST, functionalized with MRI and CT probes and loaded with mitochondria targeted CAT‐SOD nanogels, that rapidly self repairs and mechanically stabilizes the infarcted myocardium, releases therapeutic nanogels and albumin under hypoxia induced acidosis to clear mitochondrial ROS ...

Advanced Science, EarlyView.A nebulized nanoassembly alleviates radiation‐induced lung injury by reprogramming macrophages through coordinated ROS scavenging, NAD+ replenishment, and PPAR‐γ activation. Redox balance, mitochondrial homeostasis, and immune regulation are restored, revealing a microenvironment‐centered strategy for localized radioprotection.

Fallback Rates from Partial Tidal Disruption Events [PDF]
, 2020 A tidal disruption event (TDE) occurs when a star plunges through a supermassive black hole's tidal radius, at which point the star's self-gravity is overwhelmed by the tidal gravity of the black hole.

CALB2 is a Mechanoresistance Gene in Metastatic Prostate Cancer
Advanced Science, EarlyView.Prostate cancer cell lines of differing origins were cultured over many passages while being subjected to semi‐lethal levels of fluid shear stress, representing the harsh mechanical environment these cells are subjected to in the circulation during the process of distant metastasis.

Consequences of strong compression in tidal disruption events [PDF]
, 2019 The tidal disruption of a star by a supermassive black hole (SMBH) is a highly energetic event with consequences dependent on the degree to which the star plunges inside the SMBH's tidal sphere.

GSN 069 – A tidal disruption near miss [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 ABSTRACT I suggest that the quasi-periodic ultrasoft X-ray eruptions recently observed from the galaxy GSN 069 may result from accretion from a low-mass white dwarf in a highly eccentric orbit about its central black hole. At $0.21\,\rm M_{\odot }$, this star was probably the core of a captured red giant.

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024
Australian Journal of Social Issues, EarlyView.ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

BINARY DISRUPTION BY MASSIVE BLACK HOLES: HYPERVELOCITY STARS, S STARS, AND TIDAL DISRUPTION EVENTS [PDF]
, 2020 We examine whether disrupted binary stars can fuel black hole growth. In this mechanism, tidal disruption produces a single hypervelocity star (HVS) ejected at high velocity and a former companion star bound to the black hole.

Tidal disruptions of rubble piles: The case of Phobos
Astronomy & AstrophysicsContext. Many small satellites in the Solar System have sub-synchronous orbits, meaning their orbits are decaying due to tidal dissipation. Unless they have substantial material strength, they will eventually tidally disrupt before reaching their planet ...
