a team of scientists have retrieved microbe-filled water samples from deep within blood falls an area in northern antarctica with a rust-colored hue due to its iron-rich contentsantarctica is for the most part an expanse of icy whiteness except in one part where it appears a deep rusty colorlocated at the top of the continent blood falls gets its namesake hue from iron-rich water that has been locked in under the ice for 2 million yearsandfor the first time scientists were able to send a probe into the ice to take samples of the briny liquid from a channel that allows it to flow from the larger reservoir miles away to the falls in 2004a team had taken samples from the falls039 openingbut determined that light and oxygen could have altered the microbes studiedon this follow-up trip they took an icemole which as 039the antarctic sun039notesisa long rectangular metal box with a copper head and ice screw at one end capable of melting its way through iceand unlike other thermal drills the icemole doesnt just go straight down the tip can change directions even going sidewaysthe device was tracked bysending acoustic pulsesinto the ice to perform gps-like functions based on sound wavesscientists are analyzing the retrieved samples which will hopefully provide a look into the extreme microbes living in the sub-glacial world

how deep is the ocean reallydepth of sea

the deep sea or deep layer is the lowest layer in the ocean existing below the thermocline and above the seabed at a depth of 1000 fathoms 1800 m or more little or no light penetrates this part of the ocean and most of the organisms that live there rely for subsistence on falling organic matter produced in the photic zone for this reason scientists once assumed that life would be sparse in the deep ocean but virtually every probe has revealed that on the contrary life is abundant in the deep oceanin 1960 the bathyscaphe trieste descended to the bottom of the mariana trench near guam at 35798 feet or 677 miles 10911 meters the deepest known spot in any ocean if mount everest 8848 metres were submerged there its peak would be more than a mile beneath the surface the trieste was retired and for a while the japanese remote-operated vehicle rov kaik was the only vessel capable of reaching this depth it was lost at sea in 2003 in may and june 2009 the hybrid-rov hrov nereus returned

is your napping technique backed up by scientific research this one issubscribe to our channel http:googl0bsajo---it039s counterintuitive but scientists agree that drinking coffee before napping will give you a stronger boost of energy than either coffee or napping alone to understand a coffee nap you have to understand how caffeine affects you after it039s absorbed through your small intestine and passes into your bloodstream it crosses into your brain there it fits into receptors that are normally filled by a similarly shaped molecule called adenosine adenosine is a byproduct of brain activity and when it accumulates at high enough levels it plugs into these receptors and makes you feel tired but with the caffeine blocking the receptors it039s unable to do so here039s the trick of the coffee nap: sleeping naturally clears adenosine from the brain so if you nap for those 20 minutes you039ll reduce your levels of adenosine just in time for the caffeine to kick in the caffeine will have less adenosine to compete with and will thereby be even more effective in making you alert---voxcom is a news website that helps you cut through the noise and understand what039s really driving the events in the headlines check out http:wwwvoxcom to get up to speed on everything from kurdistan to the kim kardashian app check out our full video catalog: http:googlizonyefollow vox on twitter: http:googlxfrz5hor on facebook: http:googlu2g06o
