Observing eruptions of gas-rich compressible magmas from space
Nature Communications, 2016 Satellite observations are an important tool in volcano monitoring, but observations such as ground deformation and gas emissions are treated independently. Here, the authors present a model coupling them through their link to magma volatile contents and

The nucleus of 103P/Hartley 2, target of the EPOXI mission
, 2010 103P/Hartley 2 was selected as the target comet for the Deep Impact extended mission, EPOXI, in October 2007. There have been no direct optical observations of the nucleus of this comet, as it has always been highly active when previously observed.

Advanced Materials, EarlyView.Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

An investigation of changes to commercial aircraft flight paths during volcanic eruptions
Journal of Applied VolcanologyVolcanic eruptions can inject ash into the atmosphere, which is then advected by meteorological winds, potentially affecting large volumes of airspace. Volcanic Ash Advisory Centres (VAACs) issue volcanic ash advisories (VAAs) when airspace is likely to ...

EPOXI Mission: Comet on a Stick [PDF]
, 2009 In this activity, students examine their concepts of a comet by designing and building a model. The goal is to have students replicate the scientific processes of observing, modeling, forming an explanation, making new observations, and revising. In this

Advanced Science, EarlyView.Short‐term intravenous treatments with iPSC‐derived mononuclear phagocytes (iMPs) improve cognitive decline and neural health in two mouse models of aging and in the 5xFAD mouse model of Alzheimer's disease. iMPs reduce levels of serum amyloid proteins that increase in aging and improve the health of hippocampal microglia and mossy cells.

Unsupervised Anomaly Detection for Volcanic Deformation in InSAR Imagery
Earth and Space ScienceSatellite‐based Interferometric Synthetic Aperture Radar (InSAR) images have the potential to detect volcanic deformation prior to eruptions, but while a vast number of images are routinely acquired, only a small percentage contain volcanic deformation ...

Effect of Imidocarb Application on Oxidative DNA Damage Caused by Anaplasmosis
Turkish Journal of Agriculture: Food Science and Technology, 2021 This study was aimed to evaluate DNA fragmentation by using Comet assay in naturally infected sheep with Anaplasmosis before and after treatment with the Comet method, which shows DNA damage specifically.
