nursing is the job of the future so why have men stayed awaysubscribe to our channel http:googl0bsajoits easy to imagine that the jobs of the future if they even exist will all revolve around technology but it turns out the jobs that are least likely to succumb to automation are those that involve building human relationships the healthcare field is a prime example nurses physician assistants and physical therapists have higher-than-average salaries and major expected job growth these fields share something else in common theyre dominated by women despite the erosion of traditionally masculine fields like manufacturing men just arent taking these high-paying in-demand healthcare jobs in the numbers youd expect for decades nursing in particular has been considered womens work in part because its assumed that women more so than men have a kind of innate capacity for caring and empathy but men in nursing say this mindset is holding us back for them

nasa gsfc solar scientist holly gilbert explains a computer model of the suns magnetic fieldgrasping what drives that magnetic system is crucial for understanding the nature of space throughout the solar system: the sun039s invisible magnetic field is responsible for everything from the solar explosions that cause space weather on earth such as auroras to the interplanetary magnetic field and radiation through which our spacecraft journeying around the solar system must travel we can observe the shape of the magnetic fields above the sun039s surface because they guide the motion of that plasma the loops and towers of material in the corona glow brightly in euv images additionally the footpoints on the suns surface or photosphere of these magnetic loops can be more precisely measured using an instrument called a magnetograph which measures the strength and direction of magnetic fields scientists also turn to models they combine their observations measurements of the magnetic field strength and direction on the solar surface with an understanding of how solar material moves and magnetism to fill in the gaps simulations such as the potential field source surface or pfss model shown in the accompanying video can help illustrate exactly how magnetic fields undulate around the sun models like pfss can give us a good idea of what the solar magnetic field looks like in the suns corona and even on the suns far side download other resolutions from our scientific visualization studio: http:svsgsfcnasagovcgi-bindetailscgiaid=12104read more at: http:wwwnasagovfeaturegoddard2016understanding-the-magnetic-sunscience paper: photospheric and heliospheric magnetic fields by carolus j schrijver and marc l de rosa original visualization: http:svsgsfcnasagovgoto4391
