presented new insight on Deep Space 1's recent target, Comet Borrelly.

On September 22, 2001, NASA's Deep Space 1 probe proved victorious in a daring
adventure when it introduced a comet called Borrelly to the people of Earth.
In a chancy maneuver that day, Deep Space 1 altered our view of Borrelly as a
mysterious, dust-cloaked object to an exciting astrogeology subject.

Comet Borrelly was discovered at the beginning of last century. It's a Jupiter
family comet with a 6.9 year period about the Sun. It's the second comet
visited by flyby mission with nucleus photographed directly besides Comet
Halley in 1986. You can check out the published pictures of comet nucleus
from http://nmp.jpl.nasa.gov/ds1/images.html. The flyby was performed before

发帖数: 298 | 5 April 22, 2002 | Scientific intuition tells us that a comet's nucleus should
be a frozen mountain of ice and dust. But that's not what Deep Space 1
discovered when it flew past Comet 19P/Borrelly last year. A recently released
analysis of spacecraft spectra finds that Borrelly's "icy heart" exhibits no
trace of water ice or any water-bearing minerals. Moreover, the nucleus is
actually quite hot — ranging from 300° to 345° Kelvin (80° to 160° F).

特朗普就任总统的第一周，火速颁布一系列饱受争议的总统行政令，成为全球媒体的焦点。然而与此形成鲜明对比的是，第一夫人梅拉尼娅在总统就职典礼后几乎难觅踪影，同样也激起了全球媒体的好奇——她愿意做这个万人瞩目的第一夫人吗？
第一夫人办公室：关键岗位均空缺
据《华盛顿邮报》报道，据信梅拉尼娅正在组建自己的工作团队，但目前为止，作为新任第一夫人，她没有向任何媒体透露自己的打算。
《总统的代表》（On Behalf of the President）一书的作者、政治学家Lauren Wright认为，公众期待与第一夫人交流，但梅拉尼娅没有提供这个机会，“似乎没有意愿来塑造她作为第一夫人的公众形象，尽管这是公众利益的要求 。”
无论用哪种方式衡量，梅拉尼娅入主白宫东翼第一夫人办公室的进展都异常地缓慢。上周传出的消息称，第一夫人聘请了第一位工作人员，她的高级顾问、原纽约派对策划师 Stephanie Winston Wolkoff。
目前，第一夫人办公室的几个关键岗位仍然空缺，包括办公室主任、对外联络部主任和新闻秘书。其中... 阅读全帖 |

面对新型冠状病毒肺炎疫情的爆发，成为欧洲重灾区的意大利宣布北部11个市镇进
入封城隔离，违反防疫要求者将面临监禁或罚款处罚。
截至当地时间2月24日零时，意大利累计确诊新冠肺炎病例已达157例，其中三例死
亡、两人治愈出院。意大利也成为欧洲受疫情影响最严重的国家。
虽然意大利的首例确诊病例出现在罗马，但疫情爆发却集中在北部伦巴第大区。由
于传染源头不明，当局正在追查“零号病人”。
11市镇封城
据《每日电讯报》和《卫报》2月24日报道，随着意大利出现第三例死亡病例，北
部伦巴第大区和威尼托大区的11个市镇于周日开始进入封城隔离。
根据意大利总理孔特周六晚发布的行政令，封城隔离将影响伦巴第大区的10个市镇
以及威尼托大区的一个镇的共5万名居民。
在未来两周内，在没有特殊许可下，民众不得出入这11个市镇。在这11个市镇里，
学校、公司、餐馆和除药店之外的商店关闭，所有文体活动和宗教活动取消，经过该地

根据世界卫生组织的统计，截至2020年3月26日，新冠病毒已在全球夺走了至少
21306人的生命。
作为目前全球疫情的“震中”，欧洲大部分国家因新冠肺炎病亡的人数都在激增。
其中有两个国家——意大利和德国，显得特别“突出”。前者有着全球最多的病亡人数
和远远高于平均水平的死亡率，而后者则正好相反，死亡率远远低于平均水平。
美国约翰·霍普金斯大学最新数据显示，截至3月26日，意大利已累计确诊74386例
新冠肺炎病例，其中7503人病亡，死亡率高达10%。而与之邻近的德国，累计确诊37323
例，仅有206人病亡，死亡率仅为0.55%。两个国家相差18倍。
意大利和德国巨大反差引起了许多国家政府和科学家的关注。尤其值得注意的是，
根据联合国2015年全球老龄化报告：德国和意大利并列全球老龄化人口第二高、欧洲第
一高国家（60岁以上人口占28%）。彭博全球健康指数甚至表明：意大利人有着比德国
人更健康的生活方式。

Chris Matthews Is Determined To Find Out Boston Marathon Bomber’s Ethnicity
By Alex Groberman, Thu, April 18, 2013
This has been something of a rough week for Chris Matthews.
On a personal level, he got exposed as nothing more than the loud-mouthed,
flip-flopping political troll that he is when he was forced to cover the
Boston Marathon bombings – something slightly outside of his comfort zone.
Rather than buckling down and doing his best Shep Smith impr... 阅读全帖 |

deter Anderson's advances, which appear to have been racially motivated.
According to press reports, Anderson had confided to a colleague that he
