Antarctic sea ice increase consistent with intrinsic variability of the Amundsen Sea Low [PDF]

, 2015
We investigate the relationship between atmospheric circulation variability and the recent trends in Antarctic sea ice extent (SIE) using Coupled Model Intercomparison Project Phase 5 (CMIP5) atmospheric data, ECMWF Interim reanalysis fields and passive ...

Isotopic signature of massive, buried ice in eastern Taylor Valley, Antarctica: Implications for its origin

Arctic, Antarctic, and Alpine Research, 2022
The coastal regions of the McMurdo Dry Valleys, Antarctica, contain deposits of the Ross Sea Drift, sedimentary material left from the Ross Sea ice sheet from the advance of the West Antarctic ice sheet during the Last Glacial Maximum.

Long-term and recent changes in sea level in the Falkland Islands [PDF]

, 2010
Mean sea level measurements made at Port Louis in the Falkland Islands in 1981-2, 1984 and 2009, together with values from the nearby permanent tide gauge at Port Stanley, have been compared to measurements made at Port Louis in 1842 by James Clark Ross.

Modeling the effect of Ross Ice Shelf melting on the Southern Ocean in quasi-equilibrium [PDF]

The Cryosphere, 2018
To study the influence of basal melting of the Ross Ice Shelf (BMRIS) on the Southern Ocean (ocean southward of 35° S) in quasi-equilibrium, numerical experiments with and without the BMRIS effect were performed using a global ocean–sea ice–ice

Is It the Same Every Summer for the Euphausiids of the Ross Sea?

Diversity, 2022
The pelagic ecosystem in the Ross Sea has one central component that is very important for energy exchanges between upper and lower trophic levels: the Middle Trophic Level.

Unprecedented springtime retreat of Antarctic sea ice in 2016 [PDF]

, 2017
During austral spring 2016 Antarctic sea ice extent (SIE) decreased at a record rate of 75 x 10(3) km(2) d(-1), which was 46% faster than the mean rate and 18% faster than in any previous spring season during the satellite era.

Aspects of resilience of polar sea ice algae to changes in their environment [PDF]

, 2015
Sea ice algae are primary producers of the ice-covered oceans in both polar regions. Changes in sea ice distribution are potentially altering exposure to photosynthetically active radiation (PAR) and ultraviolet-B (UV-B) wavelengths of light. Incubations

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

FEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

The Aging Blood: Cellular Origins, Circulating Drivers, and Therapeutic Potential

Aging and Cancer, EarlyView.
As a conduit linking all organs, the blood system both reflects and actively drives systemic aging. This review highlights how circulating pro‐aging and antiaging factors and age‐associated hematopoietic stem cell dysfunction contribute to immunosenescence and multi‐organ decline, positioning the hematopoietic system as a target for aging intervention.

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and
