美国现在还没有转基因的小麦和水稻
转基因这种东西在科研上是必须要搞的，但远不到大规模普及的程度。中国来个大跃进
搞到水稻和小麦上让人吃有些急了。
以现在中国社会一切向钱看的风气，大规模搞转基因主食潜在的危险可能远远超过眼前
利益，况且还又是一小部分人的利益。

人体内检测出多种转基因毒素，转基因核心谎言被戳穿
翻译评论：加拿大一个彻底戳穿转基因谎言的划时代重要研究
作者/译者：半解一知半解
评论：鉴于长期以来， 国内外转基因的讨论与推广已严重偏离科学的轨道，成了一个
利益和政治问题，所以， 有必要矫枉过正把这个问题还原回科学的轨道。
不可否认， 转基因技术本身是一种科学， 但同样不可否认，不是所有的科学技术都是
完美无缺、有益无害的，转基因是一种未经严格验证、其安全性还存在很多未知和不确
定性的技术，是一种存在巨大争议和巨大风险的技术，因为这项技术涉及到食品及食品
安全，所以，在实验室进行研究、完善无可质疑，但如果大面积推广，就应该受到质疑
乃至反对。这应该是目前大多数反转基因民众和仁人志士的基本共识。

先简要介绍一下燃烧知识，碳氢化和物不完全燃烧产物包含千百种不同成分。不论是烧
甲烷为主的天然气，还是以C8H18为主的汽油，还是C12H26为主的柴油，产生的成分都
是一样的，不同的只是各个成分的浓度。如果是富油燃烧，很容易形成碳颗粒（soot)
。碳颗粒刚形成的precursor particle大小只有2-3纳米，分子量大致为2000-5000之间
，然后迅速通过表面反应形成20-40纳米大小的颗粒（期间dehydrogenation过程导致碳
原子和氢原子比例达到9：1左右,基本上成为吸收光线最有效的blackbody黑体)，分子
量达到100万左右。在这个过程中碳颗粒之间通过碰撞agglomeration过程形成类似

昨天本博转发了国外洋葱讽刺网的一篇文章，揭露西方统治势力曾经指使学者伪造希腊
历史，为希腊民主制度整容。
这里介绍一下一下何新对此问题的看法。老何说：
这篇文章揭露的根本不够。西方近代资本主义文明的根，本来就不是希腊的宗教文化而
是犹太的宗教和金钱崇拜文化。这方面可以看两个犹太学者韦伯（论证过新教的希伯来
渊源）与波普（曾经大骂希腊文明）的书。中国自由主义很膜拜这两个犹太自由主义学
者，但是看来对他们的书没有认真地读。
原生希腊人是黑头发黑眼睛的人种，与古埃及人（黄种人）接近。而与北欧那种黄头发
、蓝眼睛、满身长毛的哥特——日耳曼——盎格鲁撒克逊人根本不搭界。
事实上，古希腊人与古代罗马人都认为北欧、西欧那些白色人是没有进入文明的野蛮人
——蛮族。而就是这些希腊罗马人眼中的“蛮族”，在种族上才是现代西方多数欧美人
的祖宗。
老何说，希腊有很多城邦，多数不实行城邦“民主”制度。
雅典的城邦民主是保留氏族血缘社会时代氏族民主的残余——不是什么先进制度。中国
先夏时代——尧舜禹传说时代也是实施这种氏族民主——“选贤与能”。这方面可以看
《礼运》和《墨子》。

弹头被系统成功识别
A hit-to-kill test over the Pacific showed U.S. missile defenses can destroy
intercontinental ballistic missile targets using decoys and protect against
an eventual North Korean threat, the head of the Missile Defense Agency
said Wednesday.
Vice Adm. James Syring said Tuesday's test in which an interceptor fired
from California "completely obliterated" an ICBM-type target launched from
Kwajalein Atoll would have worked "if it had been a North Korea... 阅读全帖 |

Images taken by the Lunar Reconnaissance Orbiter mission beginning in July
2009 show the six Apollo Lunar Module descent stages, Apollo Lunar Surface
Experiment Package (ALSEP) science experiments, astronaut footpaths, and
lunar rover tire tracks. These images are the most effective proof to date
to rebut the "landing hoax" theories. Although this probe was indeed
launched by NASA, the camera and the i... 阅读全帖 |

Air Pollution Linked to 1.2 Million Premature Deaths in China
BEIJING — Outdoor air pollution contributed to 1.2 million premature
deaths in China in 2010, nearly 40 percent of the global total, according to
a new summary of data from a scientific study on leading causes of death
worldwide.
Figured another way, the researchers said, China’s toll from pollution was
the loss of 25 million healthy years of life from the population.

Posted: 07/12/2012
In a remarkable Silicon Valley rags-to-riches-to-rags saga, the onetime
social media darling Digg was sold Thursday for a reported $500,000, an
embarrassingly paltry sum given that Internet rock star Kevin Rose's company
had raised a total of $45 million in venture funding and was once valued at
more than four times that amount.
Digg's fall was spectacular in ... 阅读全帖 |

by Oliver North

WASHINGTON -- For most of the year, irrational behavior is a natural state
in our nation's capital. This is a place where potentates and politicians,
lobbyists and legislators and the elite and the lowly routinely say and do
completely irrational things.
We also have come to expect that irrational behavior takes a brief hiatus
when Congress goes home on recess and the president of the United States
heads out of tow... 阅读全帖 |

A quotation in the September 19, 1926 edition of the Chicago Tribune
included the following observation on the electorate of the day:
No one in this world, so far as I know - and I have searched the records for
years, and employed agents to help me - has ever lost money by
underestimating the intelligence of the great masses of the plain people.
Nor has anyone ever lost public office thereby.
Its author was H.L. Mencken, a noted journalist. Could it be that President
