On the Border: Searching for Cometary Activity near the Centaur–JFC Transition Line
The Planetary Science JournalCurrent wide-field surveys discover ∼15 Jupiter-family comets (JFCs) each year, typically identified via visual detection of a dust coma or tail. The same surveys also discover many asteroids that have distant JFC-like orbits, but with no reported ...

Meteoritics &Planetary Science, EarlyView.Abstract Here we report on the microstructure and chemistry of sulfide minerals returned from asteroid (162173) Ryugu. We identify a unique sulfide population in particle A0016 composed of violarite (FeNi2S4), pyrite (FeS2), chalcopyrite (CuFeS2), pyrrhotite (Fe1‐xS), and pentlandite ([Fe,Ni]9S8).

Covertly Active Comet (139359) 2001 ME1
The Planetary Science JournalOn 2018 November 18, coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) captured an unrecognized comet crossing its fields of view. We identified this comet to be the minor planet (139359) 2001 ME _1 , whose previously unnoticed dust ...

Obesity Reviews, EarlyView.ABSTRACT Introduction This scoping review aims to identify all outcomes reported in school‐based obesity prevention interventions in childhood. It serves as an essential first step towards developing an internationally agreed‐upon Core Outcome Set (COS), which defines what should be measured in all school‐based childhood obesity prevention studies ...

Gelato: A Mission Concept for Comet Surface Sample Return
The Planetary Science JournalUnderstanding the role of comets in solar system formation and evolution has continued to be a driving question in planetary science. It is believed that comets host a record of presolar history and early planet formation and likely delivered volatiles ...

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation
Photochemistry and Photobiology, EarlyView.UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

Search for the True Parent Body of the Phoenicid Meteor Shower
The Astronomical JournalIn 2024, Ďurišová et al. found that the meteor shower Phoenicids, IAU No. 254, code PHO, can originate in the nuclei of three comets, 46P/Wirtanen, 104P/Kowal 2, and 289P/Blanpain.

A Sub‐Microsecond Switch Enabling SWIFT 23Na Imaging at 10.5 T
Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1991-2003, October 2026.ABSTRACT PurposeTo enable sodium SWIFT imaging, which is a zero‐echo time imaging technique, at ultra‐high magnetic fields through the development of custom electronics hardware, and to showcase this capability with in vivo imaging results. MethodsThe custom hardware developed consists of a high‐speed optical trigger with 10 ns resolution, an in‐bore ...
