MEGA Mass Assembly with JWST: The MIRI EGS Galaxy and Active Galactic Nucleus Survey

open access: yesThe Astronomical Journal
We present the Mid-Infrared Instrument (MIRI) Extended Groth Strip (EGS) Galaxy and Active Galactic Nucleus (MEGA) survey, a four-band MIRI survey with 25 pointings in the EGS extragalactic field.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

open access: yesMolecular Oncology, Volume 20, Issue 5, Page 1161-1184, May 2026.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Infrared photometry of planetary nebulae.

open access: yesThe Astrophysical Journal, 1973
Photometric observations from 1.6 to 3.5 mu of 28 planetary nebulae are presented. Most of these emit 3.5- mu radiation in excess of that expected from thermal emission by ionized gas. When combined with the measurements of Willner, Becklin, and Visvanathan, the data show that the nebulae with relatively high densities are the more likely to emit ...

Optoelectrical Devices for Neural Interfacing: Engineering Integration, Stability, and Multimodal Sensing

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 20, 27 May 2026.
Implantable optoelectrical devices are an effective resource for the modulation and monitoring of neural activity with high spatiotemporal resolution. This review discusses current challenges faced by these devices and outlines future perspectives for the development of next‐generation neural interfaces targeting chronic, multisite, and multimodal ...

Three Thousand Motion-confirmed L and T Dwarf Candidates from the Backyard Worlds: Planet 9 Citizen Science Project

open access: yesThe Astronomical Journal
The Backyard Worlds: Planet 9 citizen science project uses data from the Wide-field Infrared Survey Explorer to detect infrared objects with significant motion. In this work, we present the majority of the L and T dwarf candidates discovered through this

Optical photometry and polarimetry and infrared photometry of 3C 345 in outburst

open access: yesThe Astrophysical Journal, 1993
We present V-band CCD photometry, UBVRI photopolarimetry, and near simultaneous JHK photometry of 3C 345 during a renewed outburst in spring of 1992, which reached maximum at the end of April. The observations also show a large and variable polarization.

Exploration of the Near-infrared Colors of Cold Y Dwarfs from the Ground and Space

open access: yesThe Astrophysical Journal
The James Webb Space Telescope (JWST) has provided critical mid-infrared data for cold brown dwarfs. It has also provided low-resolution near-infrared spectra, and for faint sources these are the first spectra at these wavelengths.
