The Correlation Between Metallicity and Debris Disk mass

, 2016
We find that the initial dust masses in planetary debris disks are correlated with the metallicities of their central stars. We compiled a large sample of systems, including Spitzer, the Herschel DUNES and DEBRIS surveys, and WISE debris disk candidates.

Novel Manufacturing of Cellulose‐Based Membranes for Energy Storage Devices: Toward a PFAS Free Future

Advanced Sustainable Systems, EarlyView.
This work presents a novel, scalable method for manufacturing PFAS‐free cellulose‐based membranes for energy storage devices. By coating kraft paper with cellulose nanofibrils and optimizing barrier and ionic conductivity properties, membranes are achieved that prevent redox molecule crossover while maintaining performance.

Runaway accretion of metals from compact debris disks onto white dwarfs

, 2011
It was recently proposed that metal-rich white dwarfs (WDs) accrete their metals from compact debris disks found to exist around more than a dozen of them.

Single‐Cell RNA Sequencing of Retina Reveals Nna1 Upregulation in Myopic Diabetic Retinopathy as a Protective Factor Against Diabetic Damage

Advanced Science, EarlyView.
This study investigates a schematic overview of the mechanistic pathways. The relationship between myopia and DR has long been of clinical interest. In diabetic mice, Nna1 expression is downregulated, whereas in diabetic mice with FDM, Nna1 expression is upregulated–particularly in Müller cells–accompanied by decreased vascular endothelial growth ...

Identifying and Characterizing Infrared Excesses in the Spitzer Kepler Survey (SpiKeS)

The Astrophysical Journal
We report our search for infrared excesses in the Spitzer/Infrared Array Camera survey of the Kepler field at 3.6 and 4.5 μ m. The Spitzer Kepler Survey contains ∼190,000 targets, which we reduce to ∼117,000 targets after applying multiple filters to ...

Debris Disks: Seeing Dust, Thinking of Planetesimals and Planets

, 2010
Debris disks are optically thin, almost gas-free dusty disks observed around a significant fraction of main-sequence stars older than about 10 Myr. Since the circumstellar dust is short-lived, the very existence of these disks is considered as evidence ...

In Situ Engineering of Tumor Cells as Self‐Sustaining cDC1 Programming Factories for Effective Cancer Immunotherapy

Advanced Science, EarlyView.
The fused EV platform AS16‐EL@MPLA/p‐FX reprograms tumor cells into cytokine‐producing factories that continuously secrete XCL1 and FLT3L to recruit and differentiate cDC1s, while embedded MPLA activates them through TLR4 signaling and AS16 prevents their exhaustion, thereby enhancing antitumor immunity and establishing durable immune memory against ...

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.

Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

Advanced Science, EarlyView.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and
