Mechanical Force Storage and Reprogramming Hydrogel for Scarless Repair of Sports Joint Wounds

Advanced Science, EarlyView.
Inspired by the energy conversion of tendons, the “energy transit station” hydrogel is designed. The hydrogel not only shields stress concentration in sports injuries, but also reprograms energy forms to provide reasonable biomimetic contraction for wounds.

Microlensing Constraints on the Stellar and Planetary Mass Functions

The Astronomical Journal
The mass function (MF) of isolated objects measured by microlensing consists of both a stellar and a planetary component. We compare the microlensing MFs of A. Gould et al. and T. Sumi et al. to other measurements of the MF. The abundance of brown dwarfs

Molecular Insights into Fungal Glycosylphosphatidylinositol Transamidase Complex

Advanced Science, EarlyView.
The glycosylphosphatidylinositol (GPI) biosynthesis pathway is critical for antifungal drug development. This study reports three cryo‐electron microscopy structures of fungal GPI transamidase (GPIT), captured in two substrate‐bound states and a novel dimeric assembly.

A Data-driven Search For Mid-infrared Excesses Among Five Million Main-sequence FGK Stars

The Astronomical Journal
Stellar infrared excesses can indicate various phenomena of interest, from protoplanetary disks to debris disks, or (more speculatively) techno-signatures along the lines of Dyson spheres.

Alpinetin Nanoparticles Alleviate Optic Nerve Injury Induced by Acute Glaucoma via LRP1‐PPARγ Mediated Regulation of Microglial Lipid Metabolism

Advanced Science, EarlyView.
Microglial lipid metabolic dysfunction drives neurodegeneration in glaucoma. We found loss of LRP1 causes lipid accumulation and inflammation. We developed alpinetin‐loaded nanoparticles (AlpNPs) that bind LRP1, activate the PPARγ‐LXRα‐ABCA1 pathway to restore lipid homeostasis, promote an anti‐inflammatory phenotype, and protect retinal ganglion cells,

On the Relationship Between Debris Disks and Planets [PDF]

, 2009
Dust in debris disks is generated by collisions among planetesimals. The existence of these planetesimals is a consequence of the planet formation process, but the relationship between debris disks and planets has not been clearly established.

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.

Linear Thermal Instability of a Condensing Gas–Particle Mixture, with Possible Application to Chondrites and Planetesimals

The Astrophysical Journal
We study the stability of a hot saturated gas coexisting with condensed particles in an optically thin medium. Such a situation may be obtained downstream of a shock, at condensation fronts, or in vaporizing impacts. We show that the gas–particle mixture
