A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

Hierarchical Bayesian inference of galaxy redshift distributions from photometric surveys [PDF]
Accurately characterizing the redshift distributions of galaxies is essential for analysing deep photometric surveys and testing cosmological models.

Dark Energy Survey Year 1 Results: redshift distributions of the weak-lensing source galaxies [PDF]
We describe the derivation and validation of redshift distribution estimates and their uncertainties for the populations of galaxies used as weak-lensing sources in the Dark Energy Survey (DES) Year 1 cosmological analyses.

ASTROMETRIC REDSHIFTS FOR QUASARS [PDF]
The wavelength dependence of atmospheric refraction causes differential chromatic refraction (DCR), whereby objects imaged at different optical/UV wavelengths are observed at slightly different positions in the plane of the detector. Strong spectral features induce changes in the effective wavelengths of broad-band filters that are capable of producing

Superionic Disulfonic Acid Polymers
A strategy is presented to enhance the mechanical and ion transport properties of acid‐functionalized polymers through controlled polymerizations of precisely designed disulfonic acid monomers with well‐defined functional group arrangements. This approach allows for fine control over molecular interactions, and unexpected hydrophobic characteristics ...

A Note on the Inverse Problem with LTB Universes
The inverse problem with Lema\^itre-Tolman-Bondi (LTB) universe models is discussed. The LTB solution for the Einstein equations describes the spherically symmetric dust-filled spacetime. The LTB solution has two physical functional degrees of freedom of

The Star Formation Rate Intensity Distribution Function--Implications for the Cosmic Star Formation Rate History of the Universe [PDF]
We address the effects of cosmological surface brightness dimming on observations of faint galaxies by examining the distribution of "unobscured" star formation rate intensities versus redshift.

The mass–concentration–redshift relation of cold and warm dark matter haloes [PDF]
We use a suite of cosmological simulations to study the mass–concentration–redshift relation, c(M, z), of dark matter haloes. Our simulations include standard Λ-cold dark matter (CDM) models, and additional runs with truncated power spectra, consistent ...

Dark Energy Survey Year 1 results: measurement of the baryon acoustic oscillation scale in the distribution of galaxies to redshift 1 [PDF]
We present angular diameter distance measurements obtained by locating the baryon acoustic oscillations (BAO) scale in the distribution of galaxies selected from the first year of Dark Energy Survey data.
