【medical-news】基因决定气味
How much you smell depends on how often you bathe, but precisely how you smell depends on your genes, a new study suggests. The body odors of identical twins are significantly more similar than the scents of unrelated people, researchers in Switzerland have found. The results could pave the way for new tools to diagnose disease or identify people based on scent.
Body odor emanates from a chemical reaction between bacteria on the skin and sweat, a secretion that itself is odorless. BO plays a role in mate selection among mice, and some experiments have suggested its importance for human mate selection as well (ScienceNOW, 18 June 2004). Among the most prevalent chemicals in body odor are at least 24 kinds of carboxylic acids. But it wasn't known how much of each of the various acids a person produces, says lead researcher Andreas Natsch, a biochemist for the Givaudan fragrance company in Dübendorf, Switzerland. 认领

你身上有多大气味取决于你多久洗一次澡，但是确切地说，你身上的气味取决于你的基因，最新的一项研究揭示。瑞士的研究者发现，同卵双生者比不相关的个体之间具有更加明显相近的体味。这一结果为疾病诊断和用体味识别人类个体提供了新的工具。 我已经稍事修改标题，请看一下，如有更合适的请更换！
