SDPR–STK38 axis controls the proliferation–differentiation balance in alveolar type II cells

Animal Models and Experimental Medicine, EarlyView.
The present study identifies SDPR as a pivotal regulator orchestrating the balance between proliferation and differentiation in alveolar type II (AT2) cells. In SDPR+/+ cells, SDPR binds to and inhibits STK38 activity, thereby sustaining GSK‐3β signaling functionality to promote cyclin D1 degradation and maintain cell cycle homeostasis.

Interaction of an Outflow with Surrounding Gaseous Clouds as the Origin of Late-time Radio Flares in Tidal Disruption Events

The Astrophysical Journal
Close encounter between a star and a supermassive black hole (SMBH) results in the tidal disruption of the star, known as a tidal disruption event (TDE).

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

Multiple tidal disruption flares in the active galaxy IC 3599 [PDF]

, 2015
Tidal disruption events occur when a star passes too close to a massive black hole and is totally ripped apart by tidal forces. It may also occur that the star is not close enough to the black hole to be totally disrupted, and a less dramatic event might

Chandra ToO observations of Gaia-discovered tidal disruption events [PDF]

, 2014
The Gaia satellite is predicted to discover more than 100 Tidal Disruption Events per year. A small fraction should have X-ray emission bright enough to allow detailed Chandra follow-up observations.

No other choice: The fracturing of reflexivity in families' pathways into (non‐)elective home education in England

British Educational Research Journal, EarlyView.
Abstract In England, education is compulsory, but schooling is not: it is legal for families to home educate their children. This form of education is officially termed by the Department for Education as ‘Elective Home Education’. As this designation implies, many families home educate as a positive and preferential ‘choice’.

ENHANCED TIDAL DISRUPTION RATES FROM MASSIVE BLACK HOLE BINARIES [PDF]

, 2009
"Hard" massive black hole (MBH) binaries embedded in steep stellar cusps can shrink via three-body slingshot interactions. We show that this process will inevitably be accompanied by a burst of stellar tidal disruptions, at a rate that can be ...

AT2022sxl: A Candidate Repeating Tidal Disruption Event in Possible Association with Two High-energy Neutrino Events

The Astrophysical Journal
We report a candidate repeating tidal disruption event (TDE), AT2022sxl, found from large-field optical survey data. Two flares with a separation time of ∼7.2 yr between the two optical peaks are observed.
