High-molecular-weight organic matter in the particles of comet 67P/Churyumov–Gerasimenko | Nature

The COSIMA mass spectrometer on the Rosetta spacecraft has analysed the solid organic matter found in dust particles emitted by comet 67P/Churyumov–Gerasimenko; this matter is similar to the insoluble organic matter extracted from carbonaceous chondrites such as the Murchison meteorite, but is perhaps more primitive.

  • Glycaemic and insulin index of four common German breads | European Journal of Clinical Nutrition

    German-style breads are recommended as a lower glycaemic index (GI) alternative, yet little data is available. Our aim was to test the GI and insulin index (II) of four breads and rolls commonly consumed in Germany. Four German bread products were tested for their GI and II in 12 healthy subjects...

    Eusocial insects, including ants and many wasp and bee species, form hierarchical communities comprising reproductive queens and sterile workers. This means that some individuals sacrifice their own reproductive potential in order to raise the offspring of others, a fact that Darwin recognized as a...
