CBS News The Hollywood director who brought the world Titanic and The Abyss is learning about the ocean in a whole new way. In a daring expedition, James Cameron traveled to the deepest part of the sea Sunday night where o stanley mug (https://www.stanley-tumbler.us) nly two other humans have been. There had to be a moment where I just stopped and just took it in and said This is where I am, I m at the bottom of the ocean, the deepest place in the world and what does that mean I just sat there looking out the window, looking out at this kind of barren, desolate, lunar plain, Cameron said. James Cameron completes record 7-mile diveJames Cameron reaches record 7-mile ocean depthJames Cameron to dive to ocean s deepest pointDeepsea Ch stanley tumbler (https://www.cups-stanley.ca) allenge Official project website Cameron descended more than 35,000 feet underwater, stanley cups uk (https://www.stanley-cups.uk) nearly seven miles below the surface. He marked his arrival on Twitter, writing, Just arrived at the ocean s deepest pt. Hitting bottom never felt so good. Cameron was alone in a 25-foot tall torpedo-shaped submarine called the Deepsea Challenger, which took him to the bottom of the Mariana Trench, the lowest part of the ocean floor. The trench is located in the middle of the Pacific Ocean about 200 miles southwest of the island of Guam. The trench covers a huge area, 120 times larger than the Grand Canyon and nearly two miles deeper than Mount Everest is tall. The trip took Cameron two hours to reach the depth. He spent about six hours exploring and collecting samples. Pictures: J Ogks Obama s Plan for Better Policing: The Good, the Bad, the Body Cameras
Have you ever wondered how fake tan lotion manages to turn people s stanley cup (https://www.stanley-cups.at) kin brown without subjecting them to UV radiation exposure Actually, it a chemical reaction that you observe all the time 8230;whenever someone is cooking meat. Writing over at his blog, Compound Interest [rimshot], British chemistry teacher Andy Brunning has put together this nifty infographic on the alchemy of tanning lotion, along with a description of the principle chemical reactions that give people that golden, radiation-free glow. The main chemical used in tanning lotions is dihydroxyacetone, commonly abbreviated as DHA. In the 1950s, Eva Wittgenstein, a scientist st stanley isolierkanne (https://www.cup-stanley.de) udying the use of DHA orally for children with glycogen defects, observed that spillages of the chemical on the skin led to coloration. Subsequent research culminated with the first tanning lotion being introduced in the 1960s. Those initial formulations, however, left much to be desired tales still abound of people transformed into hues of orange . So how does DHA work to induce the appearance of a tan Brunning explains: DHA actually acts on the dead skin cells on the surface of our skin. The amino acids in this dead layer of skin can react with DHA in order to produce chemicals called melanoidins. The reaction can be classified as a Maillard reaction 鈥?precisely the type of reaction that responsible for browning in foods such as meat when theycups stanley (https://www.cups-stanley.us) 8217;re cooked and a reaction we discussed previously when look
