Effects of motor and cognitive‐motor training on cognitive performance in healthy older adults
Journal of Neuropsychology, EarlyView.Abstract With a rapidly aging global population, identifying effective strategies to preserve cognitive health and functional independence is increasingly important. This study investigated the effects of motor and combined cognitive‐motor training on cognitive performance and well‐being in healthy older adults against a control condition. Participants

Young asteroidal fluid activity revealed by absolute age from apatite in carbonaceous chondrite
Nature Communications, 2016 Chondritic meteorites formed in the early solar system and may tell us about primary processes at that time. Here, Zhang et al. report an absolute 207Pb/206Pb isochron age (4,450±50 Ma) of apatite from a carbonaceous chondrite constraining timing of ...

Meteoritics &Planetary Science, EarlyView.Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.

Formation of nickel–iron meteorites by chemical fluid transport
ScienceOpen Research, 2016 The deposition of solid material from the gas phase via chemical vapor transport (CVT) is a well-known process of industrial and geochemical relevance. There is strong evidence that this type of thermodynamically driven chemical transport reaction plays ...

Cosmogenic Potassium in Iron Meteorites
, 2022 This project aims to reintroduce the 41K-K Cosmic ray exposure (CRE) age dating system for iron meteorites. For this, very low amounts of potassium isotopes need to be extracted from the iron meteorite. Attempts using chemical extraction methods, i.e.,

, 2023 Lunar meteorites are fragments of consolidated rock that were ejected from the Moon when it was struck by an impacting asteroid or comet, entered an Earth-crossing orbit, and survived entry through the Earth’s atmosphere, landing on Earth as a meteorite.

Noble gases and nitrogen in material from asteroid Bennu
Meteoritics &Planetary Science, EarlyView.Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Quantitative FT-IR Analysis for Chondritic Meteorites: Search for C_60 in Meteorites [PDF]
Journal of Astronomy and Space Sciences, 1998 Infrared absorption spectra of 9 bulk samples and 3 acid residues of meteorites were obtained in the mid-infrared region (4000 ~ 400 cm^(-1)). From the known composition of meteorites studied, the possible absorption modes were investigated.
