Hajj, the Muslim pilgrimage, is a large mass gathering event that involves performing rituals at several sites on specific days and times in a fixed order, thereby saddle covers requiring transport of pilgrims between sites.For the past two decades, Hajj transport has relied on conventional and shuttle buses, train services, and pilgrims walking al
In this review the history of discovery of siphonophores, from the first formal description by Carl Linnaeus in 1785 to the present, is summarized, and species richness together with a summary of world-wide distribution of this pelagic group within the clade Hydrozoa discussed.Siphonophores exhibit three basic body plans which are briefly explained
Identifying the ancestry of chromosomal segments of distinct ancestry has a wide range of applications from disease mapping to learning about history.Most methods require the use Cosmetic Set of unlinked markers; but, using all markers from genome-wide scanning arrays, it should in principle be possible to infer the ancestry of even very small segm
We have recently introduced a novel approach to time-resolved cryo-electron microscopy (cryo-EM) that affords microsecond time resolution.It involves melting a cryo sample with a laser beam to allow dynamics of the embedded particles to occur.Once the laser beam is switched off, the sample revitrifies within just Nappy Bin a few microseconds, trapp
Defining master transcription factors governing somatic and cancer stem cell identity is an important goal.Here we show that the Oct4 paralog Oct1, a transcription factor implicated in stress responses, metabolic control, and poised transcription states, regulates normal and pathologic stem cell function.Oct1(HI) cells in the colon and small intest
