We tested the hypothesis that single nucleotide polymorphisms (SNPs) within genes of the NF-κB pathway are associated with altered clinical outcome of septic shock patients. We genotyped 59 SNPs in the NF-κB pathway in a discovery cohort of septic…

Long, continuous, marine sediment records from the subpolar North Atlantic document the glacial modulation of regional climate instability throughout the past 0.5 million years. Whenever ice sheet size surpasses a critical threshold indicated by the…

Pollen recovered from core tops of deep-sea cores from offshore northwestern Western Australia were used to build climatic transfer functions applied to sediment samples from major rivers bordering the ocean in the same region and a deep-sea core…

We present a sea-ice record from northern Greenland covering the past 10,000 years. Multiyear sea ice reached a minimum between ~8500 and 6000 years ago, when the limit of year-round sea ice at the coast of Greenland was located ~1000 kilometers to…

We present measurements of the stable carbon isotope ratio in air extracted from Antarctic ice core and firn samples. The same samples were previously used by Etheridge and co-workers to construct a high precision 1000-year record of atmospheric CO2…

A suite of inorganic and organic geochemical tracers and a low-oxygen tolerant benthic faunal index (`PEB') were measured in a 14C-dated 2+m long gravity core collected on the Louisiana shelf adjacent to the Mississippi River delta to study…

This study examines the slow modulation of El Niño&8211;Southern Oscillation (ENSO) intensity and its underlying mechanism. A 10&8211;15-yr ENSO intensity modulation cycle is identified from historical and paleoclimate data by calculating the…

Boron isotopes are potentially very important to cosmochemistry, geochemistry, and paleoceanography. However, the application has been hampered by the large sample required for positive thermal ionization mass spectrometry (PTIMS), and high mass…

The time series of volcanically produced sulfate from the GISP2 ice core is used to develop a continuous record of explosive volcanism over the past 110,000 yr. We identified textasciitilde850 volcanic signals (700 of these from 110,000 to 9000 yr…

1 Air mass trajectories in the Southern Hemisphere provide a mechanism for transport to and deposition of volcanic products on the Antarctic ice sheet from local volcanoes and from tropical and subtropical volcanic centers. This study extends the…

A long-chained polyalcohol (polyol) was isolated from the glycolipid fraction of the extreme thermoacidophile Bacillus acidocaldarius. The polyol and its Smith degradation products, as well as the alkanes derived from these compounds were…

A 13 200-yr record of magnetic parameters from the Palmer Deep, western Antarctic Peninsula, records a sequence of five distinct shifts in glacimarine sedimentation coupled with century-scale variations in paleoproductivity. The five major shifts…

Among the youngest lava flows of the Pinacate volcanic field, Sonora, Mexico, is a large outpouring of tholeiite, the Ives flow. This tube-fed pahoehoe flow contrasts sharply with other Pinacate lavas in its great volume, alkali-poor composition and…

The object of the present study is to introduce a means of comparing the Vostok and marine chronologies. Our strategy has been to use the delta(18)O of atmospheric O-2 (denoted delta(18)O(atm)) from the Vostok ice core as a proxy for the delta(18)O…

Major ion series developed from new subannual scale sampling of an ice core from central Greenland are calibrated with instrumental series of atmospheric sea-level pressure recording major marine (Icelandic Low) and terrestrial (Siberian High)…
