A series of shock experiments were conducted to assess thefeasibility of the delivery of organic compounds to theEarth via cometary impacts. Aqueous solutions containingnear-saturation levels of amino acids (lysine, norvaline,aminobutyric acid, proline, and phenylalanine) were sealedinside stainless steel capsules and shocked by ballisticimpact with a steel(More)
The ChemCam instrument, which provides insight into martian soil chemistry at the submillimeter scale, identified two principal soil types along the Curiosity rover traverse: a fine-grained mafic type and a locally derived, coarse-grained felsic type. The mafic soil component is representative of widespread martian soils and is similar in composition to the(More)

Four enzymes involved in ribonucleoside and deoxyribonucleoside catabolism (deoxyribose-5-P aldolase, thymidine phosphorylase, phosphodeoxyribomutase, and purine nucleoside phosphorylase) are coded for by four closely linked structural genes on the Salmonella chromosome. The genetic order of these genes is (deoC-deoA-deoB-deoD)-serB-thr. Studies on polarity(More)
Caribou with ChemCam analysis location in white box. This rock is highly fractured and appears to have a slightly mottled coloration (Mastcam-100 image 0342MR0013820010301085E01_DWXX.IMG). (b) ChemCam RMI colorized with Mastcam. The high Mn analysis is at location 5, marked with a white arrow along with the first and last shots of the 10x1 raster. Location(More)

The structural diversity of human milk oligosaccharides (HMOs) strongly depends on the Lewis (Le) blood group status of the donor which allows a classification of these glycans into three different groups. Starting from 50 μL of human milk, a new high-throughput, standardized, and widely automated mass spectrometric approach has been established which can(More)
