Surface localization of gas sources on comet 67P/Churyumov-Gerasimenko based on DFMS/COPS data [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We reconstruct the temporal evolution of the source distribution for the four major gas species H2O, CO2, CO, and O2 on the surface of comet 67P/Churyumov-Gerasimenko during its 2015 apparition. The analysis applies an inverse coma model and fits to data

Molecular Oncology, EarlyView.Overexpression of CHRDL2 in colon cancer cells makes them more stem‐like and resistant to chemo‐ and radiotherapy. CHRDL2‐high cells have upregulation of the WNT pathway, genes involved in the DNA damage response (DDR) pathway and epithelial‐to‐mesenchymal transition (EMT). This leads to quicker repair of damaged DNA and more cell migration.

An InSAR‐GNSS Velocity Field for Iran
Geophysical Research LettersWe present average ground‐surface velocities and strain rates for the 1.7 million km2 area of Iran, from the joint inversion of InSAR‐derived displacements and GNSS data.

Krypton isotopes and noble gas abundances in the coma of comet 67P/Churyumov-Gerasimenko [PDF]
Science Advances, 2018 Noble gases in comet 67P/Churyumov-Gerasimenko indicate nonhomogenized protoplanetary disk material at its location of formation. The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis mass spectrometer Double Focusing Mass Spectrometer on board ...

, 2008 We measured organic volatiles (CH4, CH3OH, C2H6, H2CO), CO, and water in comet 8P/Tuttle, a comet from the Oort cloud reservoir now in a short-period Halley-type orbit.

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Variability in interseismic strain accumulation rate and style along the Altyn Tagh Fault
Nature CommunicationsMajor strike-slip faults that develop between strong and weaker regions are thought to focus along narrow shear zones at the rheological boundary. Here we present the InSAR-derived velocity field spanning almost the entire length of one such fault, the ...

Thermalisme et villégiature autour d’Auch
Les Cahiers de Framespa, 2021 Around Auch, in the mid-19th century, several hot springs were exploited. Small thermal establishments were set up there, but not all of them gave rise to real spas as in Castéra-Verduzan.

Evidence for the formation of comet 67P/Churyumov-Gerasimenko through gravitational collapse of a bound clump of pebbles [PDF]
, 2017 The processes that led to the formation of the planetary bodies in the Solar system are still not fully understood. Using the results obtained with the comprehensive suite of instruments onboard the European Space Agency's Rosetta mission, we present ...
