Long-term Variations in the Orbital Period of Hot Jupiters from Transit-timing Analysis Using TESS Survey Data

The Astrophysical Journal Supplement Series
Many hot Jupiters may experience orbital decays, which are manifested as long-term transit-timing variations. We have analyzed 7068 transits from the Transiting Exoplanet Survey Satellite (TESS) for a sample of 326 hot Jupiters.

A Radon Transform Perspective on Exoplanet Transits

The Astronomical Journal
Transit light curves are usually analyzed under the assumption that the transiting planet has a circular sky-projected silhouette. However, planetary rotation, tides, rings, or atmospheric inhomogeneities can produce noncircular silhouettes.

Influence of Storage Time on Functional Bulk Properties of Low‐Pressure Oxygen/Argon Plasma Modified Polypropylene Fabric

Journal of Applied Polymer Science, Volume 143, Issue 33, September 5, 2026.
Treatment of polypropylene fabric in oxygen plasma was used to impart the fabric surface with more hydrophilic surface properties. Changes in bulk properties were minimal as the modification mainly affected the fabric surface. Bulk fabric properties water retention, moisture content and wicking were monitored over a period of 33 days.

Confirming the Warm and Dense Sub-Saturn TIC 139270665 b with the Automated Planet Finder and Unistellar Citizen Science Network

The Astronomical Journal
We report the discovery and confirmation of the Transiting Exoplanet Survey Satellite (TESS) single-transit, warm and dense sub-Saturn, TIC 139270665 b. This planet is unusually dense for its size: with a bulk density of 2.13 g cm ^−3 (0.645 R _J , 0.463

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

TOI-2015 b: A Warm Neptune with Transit Timing Variations Orbiting an Active Mid-type M Dwarf

The Astronomical Journal
We report the discovery of a close-in ( P _orb = 3.349 days) warm Neptune with clear transit timing variations (TTVs) orbiting the nearby ( d = 47.3 pc) active M4 star, TOI-2015.

The Impact of Vertical Sleeve Gastrectomy on Behavioral and Reward‐Related Outcomes

Brain and Behavior, Volume 16, Issue 9, September 2026.
Vertical sleeve gastrectomy (VSG) produces robust and consistent metabolic improvements in diet‐induced obese male mice. However, post‐surgical behavioral, reward‐related, and cognitive outcomes may be dependent on dietary context, as VSG reduces operant responding for sucrose under high‐fat diet maintenance but yields no significant behavioral changes

Protein‐Stabilized Copper Nanoclusters for Microbial Inhibition‐Enabled Fresh Produce Preservation and Pesticide Removal

cMat, Volume 3, Issue 3, September 2026.
Biocompatible bovine serum albumin‐stabilized copper nanoclusters (Cu@BSA NCs) were engineered to integrate potent antimicrobial activity with efficient pesticide adsorption. The dual mechanism, involving Cu species/ROS‐mediated microbial inactivation and BSA‐facilitated pesticide capture, enables simultaneous extension of fresh produce shelf‐life by ≥

Slope Aspect Modulates Alpine Meadow Spatial Homogeneity Through Niche Differences, Not Fitness Differences

Ecology and Evolution, Volume 16, Issue 9, September 2026.
This study examines the role of slope aspect in mediating the spatial homogeneity of alpine meadow communities on the Qinghai‐Tibetan Plateau through the lens of modern coexistence theory. We found that slope aspect strongly mediated community homogeneity by altering niche differences, but not fitness differences, with this effect being significant ...
