MINDS: Detection of an Inner Gas Disk Caused by Evaporating Bodies around HD 172555

The Astrophysical Journal
Mechanisms such as collisions of rocky bodies or cometary activity give rise to dusty debris disks. Debris disks trace the leftover building blocks of planets, and thus also planetary composition.

Syntaxin 3B Mediates Light‐Dependent Interactions with STXBP1 and Arrestin 4: Distinct Roles in Rods and Cones

Advanced Science, EarlyView.
The present study investigates a cone‐specific STX3 knockout model, displaying a complete loss of cone function, a later onset reduction in rod function, and photoreceptor cell death. A cone‐specific depletion of STXBP1 and ARR4 could be observed in this model.

Anti‐Swelling Hydrogel Combined With Nucleus Pulposus Cell Exosomes and Senolytic Drugs Efficiently Repair Intervertebral Disc Degeneration

Advanced Science, EarlyView.
In this study, a bifunctional anti‐swelling hydrogel system is developed, which encapsulated anti‐senescence drugs quercetin, dasatinib, nucleus pulposus‐derived exosomes (NP‐Exo) to clear senescent nucleus pulposus cells, regulate the inflammatory disc microenvironment, and enhance nucleus pulposus cells activity, ultimately promoting the repair of ...

Argon in β Pictoris–Entrapment and Release of Volatile in Disks

The Astrophysical Journal
Chemical compositions of planets reveal much about their formation environments. Such information is well sought-after in studies of solar system bodies and extrasolar ones.

Tailored Stitching and Vertical Stacking for High‐Voltage Multifunctional Structural Batteries with Enhanced Electrochemical–Mechanical Coupling

Advanced Science, EarlyView.
A stitched, vertically stacked CFRP structural battery uses Kevlar interlaminar threads and selective PP/Elium® thermoplastics to maintain tight electrode spacing and robust electrolyte wetting. The architecture sustains electrochemical performance under bending and delivers higher pack voltage via through‐thickness series connections without ...

Vertical Structure of Gas and Dust in Four Debris Disks

The Astrophysical Journal
We present high-spectral-resolution M -band spectra from iSHELL on NASA’s Infrared Telescope Facility along the line of sight to the debris disk host star HD 32297. We also present a Gemini Planet Imager H -band polarimetric image of the HD 131488 debris

Frictional and Particle Emission Behavior of Different Brake Disk Concepts Correlated with Optical Pin Surface Characterization

Atmosphere
Brake wear emissions can be reduced by altering the surface of brake disks. A parametric study using a gray cast iron and a laser-cladded brake disk was performed in a pin-on-disk experiment with integrated optical pin surface characterization and ...
