Duplex stainless steels are desirable for use in power generation systems because of their attractive combination of strength, corrosion
resistance and cost. However, thermal embrittlement at intermediate homologous temperatures of ~475 °C and below, limits upper service temperatures
for many applications. New lean grade duplex alloys have improved thermal stability...

Sensory hair cells convert mechanical motion into chemical signals. Otoferlin, a six-C2 domain transmembrane protein linked to deafness in humans, is hypothesized to play a
role in exocytosis at hair cell ribbon synapses. To date however, otoferlin has been
studied almost exclusively in mouse models, and no rescue experiments have...

The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...

Remote national parks of the western U.S. and Alaska are not immune to contaminants of emerging
concern. Semivolatile organic compounds (SOCs) such as pesticides and PCBs can selectively deposit from
the atmosphere at higher rates in cold, high-elevation and high-latitude sites, potentially increasing risk to
these ecosystems. In the environment,...

We present high-resolution measurements of carbon
monoxide (CO) concentrations from a shallow ice core
of the North Greenland Eemian Ice Drilling project (NEEM-
2011-S1). An optical-feedback cavity-enhanced absorption
spectrometer (OF-CEAS) coupled to a continuous melter
system performed continuous, online analysis during a fourweek
measurement campaign. This analytical setup generated
stable...

Climate change models are predicting increased frequency and severity of droughts in arid and semiarid environments, and these areas are responsible for much of the world's livestock production. Because cattle (Bos taurus) grazing can impact the abundance, distribution, and ecological function of native plant and animal communities, it is important...

Remote aquatic ecosystems are exposed to an assortment of semivolatile organic compounds (SOCs) originating from current and historic uses, of local and global origin. Here, a representative suite of 57 current- and historic-use pesticides, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons were surveyed in the plasma of the western pond turtle...

The West Antarctic Ice Sheet Divide (WAIS Divide, WD) ice core is a newly drilled, high-accumulation
deep ice core that provides Antarctic climate records of
the past ~68 ka at unprecedented temporal resolution. The
upper 2850 m (back to 31.2 ka BP) have been dated using
annual-layer counting. Here we...
Analytical methods capable of trace measurement of semi-volatile organic
compounds (SOCs) are necessary to assess the exposure of tadpoles to contaminants as a
result of long-range and regional atmospheric transport and deposition. The following
study compares the results of two analytical methods, one using pressurized liquid
extraction (PLE) and the...
