Journal of Quaternary Science, EarlyView.Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

Is the Deep Martian Mantle Heterogeneous? A Reappraisal of Seismological Evidences
Geophysical Research LettersIt has been proposed that the deep Martian mantle contains distributed heterogeneities preserved since the accretion of the planet. This result relies on a multiple‐scattering interpretation of frequency‐dependent arrival times of P‐waves detected in the

Shock-induced melting of MgSiO_3 perovskite and implications for melts in Earth's lowermost mantle [PDF]
, 2004 New shock wave equation of state (EOS) data for enstatite and MgSiO_3 glass constrain the density change upon melting of Mg-silicate perovskite up to 200 GPa. The melt becomes denser than perovskite near the base of Earth's lower mantle.

Early and Progressive Spinal Cord Atrophy in Spinocerebellar Ataxia Type 1
Movement Disorders, EarlyView.Abstract Background Spinocerebellar ataxia type 1 (SCA1) is a rare, autosomal dominant neurodegenerative disorder characterized by progressive cerebellar and brainstem degeneration. Previous studies have shown that spinal cord atrophy is also a key aspect of SCA1 neuropathology.

A Facile Salt‐Assisted Dewatering for Carboxymethyl Cellulose‐Based Hydrogels
Polymer Engineering &Science, EarlyView.Dehydration efficiency of hydrogels increases with NaCl concentration during washing. ABSTRACT Natural polymer‐based hydrogels are gaining attention as an environmentally friendly alternative to petroleum‐based superabsorbent polymers. The hydrogel fabrication process involves washing and drying hydrated gels. However, due to their high hydrophilicity,
