Noble gases and nitrogen in material from asteroid Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

Meteoritics &Planetary Science, EarlyView.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

Medical and Veterinary Entomology, EarlyView.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...

How Plants May Maintain Protein Homeostasis Under Rising Atmospheric CO2

Plant, Cell &Environment, EarlyView.
ABSTRACT Vascular plants may employ several physiological mechanisms to stabilize their protein contents as atmospheric CO2 concentrations change over a day, year, decade, or century. One mechanism is that plants may rely more on soil ammonium as their nitrogen source when CO2 increases.
