The Hayabusa2 spacecraft arrived at the near-Earth carbonaceous asteroid 162173 Ryugu in 2018. We present observations of Ryugu's shape, mass, and geomorphology. has an oblate "spinning top" with a prominent circular equatorial ridge. Its bulk density, 1.19 ± 0.02 grams per cubic centimeter, indicates high-porosity (>50%) interior. Large surface boulders suggest rubble-pile structure. Surface slope analysis shows shape may have been produced from having once spun twice current rate. Coupled...
The Hayabusa2 spacecraft investigated the small asteroid Ryugu, which has a rubble-pile structure. We describe an impact experiment on Ryugu using Hayabusa2's Small Carry-on Impactor. produced artificial crater with diameter >10 meters, semicircular shape, elevated rim, and central pit. Images of resulting ejecta were recorded by Deployable CAMera 3 for >8 minutes, showing growth curtain (the outer edge ejecta) deposition onto surface. was asymmetric heterogeneous it never fully detached...
Abstract C-type asteroids 1 are considered to be primitive small Solar System bodies enriched in water and organics, providing clues the origin evolution of building blocks life. asteroid 162173 Ryugu has been characterized by remote sensing 2–7 on-asteroid measurements 8,9 with Hayabusa2 (ref. 10 ). However, ground truth provided laboratory analysis returned samples is invaluable determine fine properties other planetary bodies. We report preliminary results analyses on from particle size...
Collecting a sample of asteroid Ryugu The Hayabusa2 spacecraft recently traveled to the nearby carbonaceous collect samples and return them Earth for laboratory analysis. Morota et al. describe Hayabusa2's first collection, taken during brief touchdown on Ryugu's surface. Close-up images video sampling process allowed authors investigate surface colors morphology small scale. Relating these craters stratigraphy constrains evolution Ryugu. conclude that experienced prior period strong solar...
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. mission performed two landing operations to collect samples of surface and subsurface material, latter exposed by an artificial impact. We present images second touchdown site, finding that ejecta from impact crater was at sample location. Surface pebbles both sites show morphological variations ranging rugged smooth, similar Ryugu's boulders, shapes quasi-spherical flattened. were returned Earth on 6...
Abstract Volatile and organic-rich C-type asteroids may have been one of the main sources Earth’s water. Our best insight into their chemistry is currently provided by carbonaceous chondritic meteorites, but meteorite record biased: only strongest types survive atmospheric entry are then modified interaction with terrestrial environment. Here we present results a detailed bulk microanalytical study pristine Ryugu particles, brought to Earth Hayabusa2 spacecraft. particles display close...

The Japan Aerospace Exploration Agency (JAXA) will make the world's first solar power sail craft demonstration of photon propulsion and thin film generation during its interplanetary cruise by IKAROS (Interplanetary Kite-craft Accelerated Radiation Of Sun). spacecraft deploys spans a membrane 20 meters in diameter taking advantage spin centrifugal force. weighs approximately 310kg, launched together with agency's Venus Climate Orbiter, AKATSUKI May 2010. This be actual flying an voyage.
We investigated by immunohistochemistry the deposition of α-synuclein in brains deceased patients with parkinsonism-dementia complex (PDC) Guam. Five 13 PDC showed numerous positive neuronal inclusions and abnormal neurites, chiefly amygdala. Similar lesions were observed, although to a lesser extent, entorhinal cortex dorsal vagal nucleus. No observed motor or locus coeruleus, only small number found Sommer's sector, temporal cortex, substantia nigra. Some reminiscent cortical Lewy bodies...
Abstract Objectives: To assess and compare the cytotoxicity antimicrobial activity of six multipurpose disinfecting contact lens solutions (MPDS). Method: Six MPDS were assessed compared: MeniCare Soft , Complete Moisture Plus Solo‐Care Aqua Opti‐Free Express ReNu MultiPlus MoistureLoc . Cytotoxicity was evaluated by means colony‐forming assay (ISO 10993‐5) using one cell line. One hundred Chinese hamster's fibroblast V79 cells in 2 mL medium inoculated into 6‐well plates cultured for 24 h....
Crossed cerebellar diaschisis (CCD) refers to reduced metabolism and blood flow in the hemisphere contralateral a cerebral lesion. Many cortical areas have been reported cause CCD without consideration of confounding factors. We performed single-photon emission computed tomography (SPECT) patients with infarction identify regions independently related CCD, controlling for possible effects.Patients unilateral (n=113; 75 male, 38 female; mean+/-SD age, 66+/-13 years) underwent SPECT brain...
Abstract To explore an easily accessible and reproducible model for examining the effect of minoxidil on hair growth, we studied natural cycles rats from birth to 80 days age. During 1st 2nd postnatal cycles, follicles grew very rapidly size anagen were markedly enlarged. In 3rd cycle (50 approximately 100 age), duration telogen phase lasted 20 days. Topical minoxidil, 1%, 3%, or 5% solution, applied backs 23 (weaning) days, induced a remarkable shortening in cycle. Although dose‐dependent...
