Salt giants are massive salt deposits (hundreds of metres thick) that form during the evaporation of semi-enclosed seas. The drivers of salt giant formation and their feedbacks on global and regional environmental change remain debated. In this Review, w
its secretion was mediated by the flagellum and MakA was shown to function as a potent virulence factor in both zebrafish andC. elegans, implying that it functions as an environmental fitness factor forV. choleraeagainst predatory organisms in its natural aquatic habitats [4]. MakA protein...
About 50 years ago, we started keeping time with atomic clocks---clocks that operate according to the oscillations of a tiny atom.---and in order to keep these clocks in step with the earth, we add an extra second every now and again. 'We're confusing the measurement of time with ...
and subjective changes evoked by VRISE have been identified. There is a great difficulty in claiming that these changes are directly caused by VRISE due to numerous other factors that are known to alter these variables resting states. Several theories exist regarding the causation of VRISE. ...
Among the different factors responsible for pregnancy loss after implantation, diminished production of progesterone is particularly frequent after ART treatments, although it can also occur after natural conception [73]. At the beginning of pregnancy, progesterone is almost exclusively secreted by the cor...
tide, any of the cyclic deformations of one astronomical body caused by the gravitational forces exerted by others. The most familiar are the periodic variations insea levelonEarththat correspond to changes in the relative positions of theMoonand theSun. The tides may be regarded as forcedwaves,...
The mathematics of networks is a common language to describe the large-scale structure of vastly different systems throughout the natural, social, and formal sciences. From power grids to the neural system; from the narrative structure of novels to subway systems; from friendship contacts to money...
. The general post-operative health of the mice was monitored daily and we did not observe any significant changes in body weight (Supplementary Fig.3C). To investigate the effects of GQ1b on cognition, we performed a non-stressful cognitive test, the novel object recognition test (Fig.2B),...
Another definition of scarcity is based on the imbalance between supply and demand created by intra-annual and inter-annual fluxes which are manifested due to lack of freshwa- ter natural or constructed storage, a fact that makes inadequate storage, i.e., storage scarcity, an equivalent ...
