    Notes: [Auszug] A LETTER appeared in NATURE of Oct. 24, 1931, signed by Messrs. Leakey, Hopwood, and Reck, in which, among other conclusions, it is stated that “there is no possible doubt that the human skeleton came from Bed No. 2 and not from Bed No. 4”. This must be taken to mean that the skeleton is to be ...

    Notes: [Auszug] Not all tissues respond in the same degree to the in vivo administration of thyroxine. Gordon and Heming8 found that the oxygen consumption of slices of liver, kidney, diaphragm and heart from thyrotoxic rats was significantly greater than normal, while that of slices of spleen, brain and testis ...

    Notes: [Auszug] WE are glad to find from Dr. Leakey's letter in NATURE of May 14 that he is in agreement with us in regarding the Oldoway skeleton as an artificial burial, and regret that, in common with everyone else whom we have consulted in this matter, we interpreted his original letter in NATURE of Oct. ...

    Notes: [Auszug] SIR—Because the cell line TE671 is said to originate from an early culture of a human medulloblastoma1, it has been widely used to investigate this tumour type and as a model for primitive neural cells in general. And because the cell line can be infected by the AIDS virus HIV2 (in a way ...

    Notes: [Auszug] P190 is a heterodimer of two disulphide-linked subunits: a 50K a-chain which is exposed at the cell surface and a 145K /3-chain that spans the plasma membrane and includes sites for tyrosine phosphorylation5'6. Recently, it has been proposed that the protein encoded by the c-met proto-oncogene may ...

    Description: The closure of ancient oceans created a dynamic setting suitable for craton formation via the thickening of continental material over a mantle downwelling. This process subjected the thickening lithosphere to extensive deformation, forming internal structure that can be preserved over the lifetime of the craton. Recent seismic imaging of cratonic lithosphere has led to observations of anomalous features colloquially known as midlithospheric discontinuities. These discontinuities are attributed to a range of sources, including the lithosphere-asthenosphere boundary, melt accumulation, and phase transitions. However, the internal structure imaged within these cratons might be reflective of their formation. In particular, the orientation and nature of the variable depths of the midlithospheric discontinuities suggest a more complicated origin such as that which could be introduced during the formation and thickening phase of cratonic lithosphere. Here, we present geodynamic models demonstrating the internal structures produced during the formation of cratonic lithosphere as well as new seismological observations of midlithospheric discontinuities in the West African craton, together with reassessment of midlithospheric discontinuities observed in the North American, South African, Fennoscandia, and Australian cratons. We suggest that the midlithospheric discontinuities observed in these cratons could be remnants of deformation structures produced during the formation of the cratons after ancient oceans closed.
