Observation and analysis of in situ carbonaceous matter in Nakhla: Part I [PDF]

, 2006
New analyses of indigenous secondary material in the martian meteorite Nakhla reveal amorphous carbon-rich veins and dendrites. The texture and chemistry of this material resembles that of biogenically altered sub-ocean basaltic ...

Mixed Representation RPA Calculation for Octupole Excitations on Superdeformed Sates in the 40Ca and Neutron-Rich Sulfur Regions

, 2005
By means of the mixed representation RPA based on the Skyrme-Hartree-Fock mean field, we investigate low-frequency octupole excitations built on the superdeformed (SD) states in the N=Z nuclei around 40Ca and the neutron-rich Sulfur isotopes.

Sulfur isotopes in otoliths allow discrimination of anadromous and non-anadromous ecotypes of sockeye salmon (Oncorhynchus nerka) [PDF]

, 2010
Oncorhynchus nerka occur both as anadromous sockeye salmon that spend most of their life in the ocean, and as non-anadromous kokanee salmon that remain in fresh water their entire lives.

Gut microbiome‐derived metabolites show promise in cancer research and therapy

Interdisciplinary Medicine, EarlyView.
The metabolites produced by the gut microbiome, which are subject to regulation by multiple factors, play a pivotal role in the progression of various types of cancer. These metabolites not only function as potential biomarkers for the early detection and monitoring of tumor development, but also actively participate in cancer therapeutic processes ...
