Description and terrestrial ages of the Calama Area Meteorite Collection (Atacama Desert, Chile)

Meteoritics &Planetary Science, EarlyView.
Abstract We present a comprehensive study of a meteorite collection from the Atacama Desert (Chile), the driest and most climatically stable desert in the world. This collection includes meteorites from three adjacent Dense Collection Areas (DCAs) in the northern part of the Atacama Desert: Calama, Sierra Gorda, and Chug Chug, referred to as the ...

Revisiting olivine‐phyric shergottites: Pyroxene crystallization pressure and the role of undercooling

Meteoritics &Planetary Science, EarlyView.
Abstract Shergottites are the most abundant meteorites from Mars and a major source of information on magma reservoirs, transport, and eruption, particularly in the late Hesperian northern hemisphere. Conflicting interpretations have arisen on the crystallization conditions of pyroxene in olivine‐phyric shergottites.

Transit timing at Torun Center for Astronomy

, 2011
The transit monitoring is one of well-known methods for discovering and observing new extrasolar planets. Among various advantages, this way of searching other worlds does not require complex and expensive equipment - it can be performed with a ...

High‐pressure phase preservation in ordinary L‐chondrite melt veins: Evidence for control by post‐shock thermal evolution

Meteoritics &Planetary Science, EarlyView.
Abstract This study investigates the petrography and mineralogy of three L‐type ordinary chondrite meteorites: Northwest Africa (NWA) 4137 (L6), Homestead (L5), and Kunashak (L6). We studied the shock‐related deformation features in the matrix and the characteristics of the melt veins, including the presence or absence of high‐pressure (HP) phases. Our

The Role of torS and torT Transcription in Driving a Bet‐Hedging Strategy for Trimethylamine N‐Oxide Reductase Expression in Escherichia coli

Molecular Microbiology, EarlyView.
Low basal activity of divergent promoters driving transcription of the trimethylamine N‐oxide (TMAO) sensor TorT and kinase TorS is integral to an O2‐regulated bet‐hedging strategy for continued E. coli growth upon the onset of anaerobiosis. This, along with repression by IscR, promotes noise in the TorS to TorT ratio, which is critical for adaptation ...

Women in Astronomy (Free Astronomy Public Lectures)

, 2014
Scientific literacy is required if we want our global society to succeed, but for a variety of reasons, science isn't a passion for most people, and most of the people in science are stereotypical white men.
