Matsumoto M, Matsuno J, Tsuchiyama A, Nakamura T, Enokido Y, Kikuiri M, et al.
Sci Adv . 2024 Jan; 10(3):eadi7203. PMID: 38241366
The Hayabusa2 spacecraft delivered samples of the carbonaceous asteroid Ryugu to Earth. Some of the sample particles show evidence of micrometeoroid impacts, which occurred on the asteroid surface. Among those,...

Morita M, Yui H, Urashima S, Onose M, Komatani S, Nakai I, et al.
Anal Chem . 2023 Dec; 96(1):170-178. PMID: 38155534
Characterization of the elemental distribution of samples with rough surfaces has been strongly desired for the analysis of various natural and artificial materials. Particularly for pristine and rare analytes with...

Zeichner S, Aponte J, Bhattacharjee S, Dong G, Hofmann A, Dworkin J, et al.
Science . 2023 Dec; 382(6677):1411-1416. PMID: 38127762
Polycyclic aromatic hydrocarbons (PAHs) contain ≲20% of the carbon in the interstellar medium. They are potentially produced in circumstellar environments (at temperatures ≳1000 kelvin), by reactions within cold (~10 kelvin)...

Amano K, Matsuoka M, Nakamura T, Kagawa E, Fujioka Y, Potin S, et al.
Sci Adv . 2023 Dec; 9(49):eadi3789. PMID: 38055820
The carbonaceous asteroid Ryugu has been explored by the Hayabusa2 spacecraft to elucidate the actual nature of hydrous asteroids. Laboratory analyses revealed that the samples from Ryugu are comparable to...

Yokoyama T, Wadhwa M, Iizuka T, Rai V, Gautam I, Hibiya Y, et al.
Sci Adv . 2023 Nov; 9(45):eadi7048. PMID: 37939187
Studies of material returned from Cb asteroid Ryugu have revealed considerable mineralogical and chemical heterogeneity, stemming primarily from brecciation and aqueous alteration. Isotopic anomalies could have also been affected by...

Miyazaki A, Itoi-Ochi S, Hayashi M, Ota A, Nagai K, Inoue S, et al.
Case Rep Dermatol . 2023 Oct; 15(1):126-132. PMID: 37899945
Linear IgA disease (LAD) is a rare autoimmune bullous disease characterized by IgA deposition in the basement membrane zone (BMZ). A 66-year-old male was treated for myelodysplastic syndrome at our...

Nat Commun . 2023 Oct; 14(1):6525. PMID: 37845217
The sample from the near-Earth carbonaceous asteroid (162173) Ryugu is analyzed in the context of carbonaceous meteorites soluble organic matter. The analysis of soluble molecules of samples collected by the...

Nat Commun . 2023 Sep; 14(1):5284. PMID: 37723151
Samples from the carbonaceous asteroid (162173) Ryugu provide information on the chemical evolution of organic molecules in the early solar system. Here we show the element partitioning of the major...

Kimura Y, Kato T, Tanigaki T, Akashi T, Kasai H, Anada S, et al.
Sci Rep . 2023 Aug; 13(1):14096. PMID: 37644091
In the samples collected from the asteroid Ryugu, magnetite displays natural remanent magnetization due to nebular magnetic field, whereas contemporaneously grown iron sulfide does not display stable remanent magnetization. To...

Nguyen A, Mane P, Keller L, Piani L, Abe Y, Aleon J, et al.
Sci Adv . 2023 Jul; 9(28):eadh1003. PMID: 37450600
Preliminary analyses of asteroid Ryugu samples show kinship to aqueously altered CI (Ivuna-type) chondrites, suggesting similar origins. We report identification of C-rich, particularly primitive clasts in Ryugu samples that contain...
