Treatment with Plasma Activated (Salt) Water Sterilizes Macromolecular Coatings While Maintaining Their Integrity and Functionality

Advanced Materials Interfaces, EarlyView.
PDMS samples were covalently coated with mucin glycoproteins and then treated with either plasma activated water (PAW) or saline (PAS) as a means of disinfection. The samples could be successfully sterilized without compromising the structural integrity or functionality of those coatings.

New Cold Subdwarf Discoveries from Backyard Worlds and a Metallicity Classification System for T Subdwarfs

The Astrophysical Journal
We report the results of a spectroscopic survey of candidate T subdwarfs identified by the Backyard Worlds: Planet 9 program. Near-infrared spectra of 31 sources with red J  − W2 colors and large J -band reduced proper motions show varying signatures of ...

From Brittle to Flexible: Influence of Glucose‐Based Additives on Cellulose Nanocrystal Self‐Assembly in Suspension and Dried Photonic Films

Advanced Optical Materials, EarlyView.
Cellulose nanocrystals (CNCs) self‐assemble in aqueous suspension into chiral nematic liquid crystals, resulting in structurally colored films upon drying. Here, the influence of sugar additives on CNC self‐assembly in suspension and in films are studied.

Eight New Substellar Hyades Candidates from the UKIRT Hemisphere Survey

The Astronomical Journal
We have used the UKIRT Hemisphere Survey combined with the UKIDSS Galactic Cluster Survey, the UKIDSS Galactic Plane Survey, and the CatWISE2020 catalog to search for new substellar members of the nearest open cluster to the Sun, the Hyades.

The Future of Research in Cognitive Robotics: Foundation Models or Developmental Cognitive Models?

Advanced Robotics Research, EarlyView.
Research in cognitive robotics founded on principles of developmental psychology and enactive cognitive science would yield what we seek in autonomous robots: the ability to perceive its environment, learn from experience, anticipate the outcome of events, act to pursue goals, and adapt to changing circumstances without resorting to training with ...

UNCOVER: JWST Spectroscopy of Three Cold Brown Dwarfs at Kiloparsec-scale Distances

The Astrophysical Journal
We report JWST/NIRSpec spectra of three distant T-type brown dwarfs identified in the Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization (UNCOVER) survey of the Abell 2744 lensing field.

Electronic Nose for Indoor Mold Detection and Identification

Advanced Sensor Research, EarlyView.
This study explores the potential of a SnO2 nanowire‐based chemiresistive electronic nose not only to detect but also to identify two common indoor mold species, Stachybotrys chartarum and Chaetomium globosum on two different growth substrates. In a laboratory setup, the electronic nose displays high classification performance using optimized linear ...

Three Brown Dwarfs Masquerading as High-redshift Galaxies in JWST Observations

The Astrophysical Journal
We report the spectroscopic identification of three brown dwarf candidates—o005_s41280, o006_s00089, and o006_s35616—discovered in RUBIES using James Webb Space Telescope (JWST) Near-Infrared Spectrograph PRISM/CLEAR spectroscopy.

Directing the Mobility of Guest Molecules in Nanoporous Materials by Linearly Polarized Light

Advanced Science, EarlyView.
The polarization of light is introduced as a further parameter to dynamically and reversibly control the properties of a photoresponsive nanoporous material. It was used to control the mobility of the guest molecules in the pores of a metal–organic framework.

Subicular Astrocytes Govern Seizure‐Impaired Fear Memory

Advanced Science, EarlyView.
Astrocytes in dorsal subiculum act as a critical modulator of seizure‐associated cognitive dysfunction, operating through a Ca2+‐dependent adenosine‐linked astrocyte‐neuron signaling pathway that disrupts neuronal circuit homeostasis. This research highlights the potential of astrocyte‐targeted interventions as a therapeutic strategy, moving beyond the
