Detection of lithium in nearby young late-M dwarfs

, 2016
Late M-type dwarfs in the solar neighborhood include a mixture of very low-mass stars and brown dwarfs which is difficult to disentangle due to the lack of constraints on their age such as trigonometric parallax, lithium detection and space velocity ...

Herschel/PACS photometry of transiting-planet host stars with candidate warm debris disks [PDF]

, 2014
Dust in debris disks is produced by colliding or evaporating planetesimals, remnants of the planet formation process. Warm dust disks, known by their emission at < 24 micron, are rare (4% of FGK main sequence stars) and especially interesting because ...

Beyond Bioactive Glass Composition: Using Morphology to Improve in Vitro and in Vivo Performance

Advanced Healthcare Materials, EarlyView.
Bioactive glasses can easily be shaped into granules, spheres, discs, fibers, or three‐dimensional scaffolds. The resulting morphology not only affects handling properties; it has a direct influence on various glass properties, including results of acellular immersion experiments or in vitro studies with cells or bacteria, but also on in vivo ...

Imaging of the Vega Debris System Using JWST/MIRI

The Astrophysical Journal
We present images of the Vega planetary debris disk obtained at 15.5, 23, and 25.5 μ m with the Mid-Infrared Instrument on JWST. The debris system is remarkably symmetric, smooth, and centered accurately on the star.

CIRCUMSTELLAR DEBRIS DISKS: DIAGNOSING THE UNSEEN PERTURBER [PDF]

, 2016
The first indication of the presence of a circumstellar debris disk is usually the detection of excess infrared emission from the population of small dust grains orbiting the star.

Geometry‐Guided Osteogenesis in Bone‐on‐a‐Chip Systems Using Triply Periodic Minimal Surface Scaffolds

Advanced Healthcare Materials, EarlyView.
This study presents a bone‐on‐a‐chip platform incorporating TPMS scaffolds to study geometry‐dependent osteogenesis under dynamic flow. By tuning pore shape and solidity, it precisely controls mechanical cues, revealing how topological features and shear stress affect osteogenic differentiation and matrix formation.

JWST-TST High Contrast: Asymmetries, Dust Populations, and Hints of a Collision in the β Pictoris Disk with NIRCam and MIRI

The Astronomical Journal
We present the first JWST Mid-Infrared Instrument (MIRI) and Near Infrared Camera (NIRCam) observations of the prominent debris disk around β Pictoris.

Insights into Planet Formation from Debris Disks [PDF]

, 2016
Giant impacts refer to collisions between two objects each of which is massive enough to be considered at least a planetary embryo. The putative collision suffered by the proto-Earth that created the Moon is a prime example, though most Solar System ...

Growth Hormone‐Loaded 3D Printed Silk Fibroin‐Cellulose Dressings for Ischemic Wounds

Advanced Healthcare Materials, EarlyView.
3D‐printed wound dressings combining carboxymethyl cellulose, silk fibroin, and growth hormone accelerate healing in diabetic ulcers. These bioactive, customizable dressings enhance angiogenesis, cellular proliferation, and immune modulation. Proteomic analysis reveals activation of regenerative pathways and reduced fibrosis, highlighting their ...

The Kuiper Belt and Other Debris Disks

, 2008
We discuss the current knowledge of the Solar system, focusing on bodies in the outer regions, on the information they provide concerning Solar system formation, and on the possible relationships that may exist between our system and the debris disks of ...
