1. Basil is good to have around. an examination: chili pepper can be encouraged by brasil growing around. This finding can be used to boost crop yeilds neighbourly.
2.Dolphines, no matter dead or living, have similar diet, and mostly a kind of fish that lives in seagrass. what's more, the results indicates we have a fine data close to shore.
3.If a bill passes the senate, helium crisis could be delayed. Conrete action is the stockpile would be sold until there are 85million cubics left.
4.the rest storage restricts the users and the main gas players will be Q,A, and R.
R: can meet over 3/4 of the total amount
Q: can meet 20%
the high price may bother labs but funding agencies are ready to help,in addition helium sparing equipment seems necessary.
5.The moon clung to magnetic field about 160 million yrs longer than previously thought.
evidence: rocks collected during Apollo missions show that.
the stirrings :1) extra terrestrial impact 2) heat differences
and the new finding rules out the first option.
However, the advocates on the impact stirring insist that impact somewhat generate the fileld.
Further conclusion need new evidence to show whether the dynamo lasted beyond 3.5 yrs ago.
越障框架:
point:主要讲口红的历史(强调的是其成分是有毒的。)
从有口红开始就有诸如铅之类的有毒物质作为其成分出现,目前,制造商开始寻找有机路线。
例子:研究人员发现32种来自不同地方的不同的口红都含有镉,铬,铝,锰这些工业重金属,这对健康是有潜在威胁的。
进一步解释:涂口红的妇女每天都在微量摄入这些重金属。
而镉会导致畏寒,肌肉疼痛,严重的是心里衰歇
铬会导致胃溃疡和肺部中毒。
锰的摄入超标会损害神经系统。
*不像是铝,可以被体内的酸性物质氧化,铬的摄入是没有安全剂量范围的(只要摄入就有毒)
可惜目前还没有监管机构去控制口红成分中这些金属的含量。
事实上,这些金属不是制作口红的必须成分,而是工业机械污染导致的。
举例:07年评选出的最安全的33只口红品牌无一例外地含有铅。而铅是没有安全剂量可言的。
口红含有的其他成分:蜜蜡,色素,蓖麻,胭脂。(它们来自动物脂肪,染料,蓖麻油还有虫子。)
即便是来自天然的成分,古时候的口红也是有毒的,这就是美丽的代价。
谢谢胖胖翔~~~辛苦了~~
