Spectrally blue hydrated parent body of asteroid (162173) Ryugu [PDF]
Nature Communications, 2021 Both poles of asteroid Ryugu, the target of space mission Hayabusa2, preserve the least processed material by space weathering. Here, the authors show detection of 700 nm absorption band in the polar spectra of Ryugu, that allows to constrain the ...

Reconnecting groups of space debris to their parent body through proper elements [PDF]
Scientific Reports, 2021 Satellite collisions or fragmentations generate a huge number of space debris; over time, the fragments might get dispersed, making it difficult to associate them to the configuration at break-up.

Reduced and unstratified crust in CV chondrite parent body [PDF]
Nature Communications, 2017 Meteorites may unlock the history of the early solar system. Here, the authors find, through Ca-Fe-rich secondary phases, that the distinction between reduced and oxidized CV chondrites is invalid; therefore, CV3 chondrites are asteroid fragments that ...

Correlated iron isotopes and silicon contents in aubrite metals reveal structure of their asteroidal parent body [PDF]
Scientific Reports, 2021 Iron isotopes record the physical parameters, such as temperature and redox conditions, during differentiation processes on rocky bodies. Here we report the results of a correlated investigation of iron isotope compositions and silicon contents of ...

A scoping review protocol of existing body image guidelines for parents of youth. [PDF]
PLoS ONEBody image concerns are commonly experienced by youth in sport and contribute to worse sport experiences and dropout. Parents are positioned to ensure the sport environment is safe and positive for their child, but they do not feel equipped to help their

Parent-child resemblance in weight status and its correlates in the United States. [PDF]
PLoS ONE, 2013 Few studies have examined parent-child resemblance in body weight status using nationally representative data for the US.We analyzed Body Mass Index (BMI), weight status, and related correlates for 4,846 boys, 4,725 girls, and their parents based on US ...
