abstract：:Non-volcanic tremor is a weak, extended duration seismic signal observed episodically on some major faults, often in conjunction with slow slip events. Such tremor may hold the key to understanding fundamental processes at the deep roots of faults, and could signal times of accelerated slip and hence increased seismic...

abstract：:Gene targeting in mouse embryo-derived stem cells has been used to disrupt the homeobox gene hox-1.5. Mice heterozygous at the hox-1.5 locus appear normal, whereas hox-1.5-/hox-1.5- mice die at or shortly after birth. These homozygotes are athymic, aparathyroid, have reduced thyroid and submaxillary tissue and exhibit...

abstract：:Cyclic ADP-ribose (cADPR) is a newly identified nucleotide which can release calcium from a variety of cells, suggesting it is a messenger for mobilizing internal Ca2+ stores. Its cyclic structure has now been confirmed by X-ray crystallography. Available results are consistent with it being a modulator of Ca(2+)-indu...

abstract：:Nutrients, such as amino acids and glucose, signal through the Rag GTPases to activate mTORC1. The GATOR1 protein complex-comprising DEPDC5, NPRL2 and NPRL3-regulates the Rag GTPases as a GTPase-activating protein (GAP) for RAGA; loss of GATOR1 desensitizes mTORC1 signalling to nutrient starvation. GATOR1 components h...
