Search for impact ejecta at the Paleocene–Eocene boundary

Meteoritics &Planetary Science, EarlyView.
Abstract Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM).

Visible, near‐, and thermal infrared spectra of asteroid Bennu samples: Relationship to and implications for remote sensing of carbonaceous asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract Remote spectroscopy is used to characterize the mineralogy and infer the history of planetary bodies. Carbonaceous asteroids, such as B‐type (101955) Bennu, represent the earliest stages of planet formation. B types have a blue (negative) spectral slope and comprise <5% of asteroids.

Raman analysis of organic refractory materials after energetic processing: Evidence for amorphous carbon on TNOs and comets

Meteoritics &Planetary Science, EarlyView.
Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.

Evaluating School‐Based Obesity Prevention Interventions in 6‐ to 12‐Year‐Old Children: A Scoping Review of All Reported Outcomes and Expert Consultation

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 ...
