The capacity for symbiosis between photosynthetic microalgae and early diverging lineages fungi was demonstrated with microscopy and stable isotope exchange of carbon and nitrogen.

Proteomic and metabolomic analyses reveal how mannose exerts its anticancer activity.

The ability of photosynthetic algae to enter the hyphae of a soil fungus could tell us more about the evolution of these species.

Transcriptomic, enzyme activity, and flux data demonstrate that metabolic scaling, the inverse correlation between body size and metabolic rate per gram of tissue, is a conserved phenomenon that occurs at multiple physiological levels and in multiple tissues.

Exosomes from cancer-associated fibroblasts enhance the "Warburg effect" in tumors and contain de novo metabolites that can contribute to the entire compendia of central carbon metabolism within cancer cells.

Stable isotope labeling reveals that NAD crosses the inner membrane of mammalian mitochondria via an unknown transporter.

Labeling with ¹³C and ¹⁵N in the absence of metabolic engineering enabled the exploration of peptidoglycan metabolism at a very fine level of detail based on kinetic characterization of isotopologues predicted to occur according to known recycling and biosynthesis pathways.

Isotope tracing into macromolecules enables functional analysis of metabolism in specific cell populations in tumors and provides insight into metabolic differences between cancer and stromal cells in their endogenous microenvironment.

Two therapsid clades, dicynodonts and cynodonts, independently acquired and developed an endotherm-like thermoregulation during the Late Permian period, that probably helped them to survive the major global climate and environmental fluctuations of the end-Permian.
