Developmental Hypoxia Enhances Kidney Organoid Complexity and Maturity

Advanced Science, EarlyView.
The current bottleneck in metanephric mesenchyme (MM)‐derived nephron organoid development is the absence of a connected network of collecting ducts (CD) derived from the ureteric bud (UB). To address this limitation, this study proposes a hypoxia‐based differentiation method that mimics the natural renal developmental environment, enabling the ...

Exploring the Evolution of Massive Clumps in Simulations That Reproduce the Observed Milky Way α-element Abundance Bimodality

The Astrophysical Journal, 2023
The Milky Way (MW) stellar disk has both a thin and a thick component. The thin disk is composed mostly of younger stars (≲8 Gyr) with a lower abundance of α -elements, while the thick disk contains predominantly older stars (≳8–12 Gyr) with a higher α ...

The Optical Properties of Gravitational Lens Galaxies as a Probe of Galaxy Structure and Evolution [PDF]

, 1997
We combine photometry and lens modeling to study the properties of 17 gravitational lens galaxies between z = 0.1 and ~1. Most of the lens galaxies are passively evolving early-type galaxies, with a few spirals.

The decade of galaxy formation: pitfalls in the path ahead

, 2010
At the turn of the decade we arguably move from the era of precision cosmology to the era of galaxy formation. One approach to this problem will be via the construction of comprehensive galaxy samples. In this review I take the opportunity to highlight a

The simulation of molecular clouds formation in the Milky Way [PDF]

, 2012
Using 3D hydrodynamic calculations we simulate formation of molecular clouds in the Galaxy. The simulations take into account molecular hydrogen chemical kinetics, cooling and heating processes.

The TET3/GATA6 Axis Drives Lipid Metabolism and Therapeutic Vulnerabilities in Pancreatic Ductal Adenocarcinoma

Advanced Science, EarlyView.
The DNA demethylase TET3 drives lipid metabolic reprogramming in pancreatic ductal adenocarcinoma via a non‐catalytic mechanism. TET3 recruits histone deacetylases to repress GATA6, sustaining lipogenic enzyme expression and ferroptosis resistance.

SDSS-III Baryon Oscillation Spectroscopic Survey Data Release 12: galaxy target selection and large-scale structure catalogues [PDF]

, 2015
The Baryon Oscillation Spectroscopic Survey (BOSS), part of the Sloan Digital Sky Survey (SDSS) III project, has provided the largest survey of galaxy redshifts available to date, in terms of both the number of galaxy redshifts measured by a single ...

Malin 1: interacting galaxy pair?

, 2010
Malin 1 is a unique, extraordinarily large low surface brightness galaxy. The structure and the origins of the galaxy are poorly understood. The reason for such a situation is an absence of detailed observational data, especially, of high-resolution ...

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring

Advanced Science, EarlyView.
Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...

Insights into Galaxy Morphology and Star Formation: Unveiling Filamentary Structures around an Extreme Overdensity at z ∼ 1.5 Traced by [O ii] Emitters

The Astrophysical Journal Letters
We explore the morphological features and star formation activities of [O ii ] emitters in the COSMOS UltraDeep field at z ∼ 1.5 using JWST NIRCam data from the COSMOS-Web survey and Subaru Hyper Suprime-Cam.
