Sunspots are cold solar regions where strong magnetic
field locate (about 0.2 Tesla). The magnetic filed lines
extend to the solar corona, with hot plasma (almost
million degrees) together with them. Due to some
motions, positive magnetic field collide with the
nagative field lines, heat will be emitted from
the cancellation of magnetic energies, and particles
will be accelerated. Flares occur, and large amount
of particles are ejected from the solar corona.
So, flares occur above the sunspots.

Astronomical discoveries in 2012 have reshaped what we know about the
universe and pushed some instruments to the very limits of their observing
power.
Scientists discovered a galaxy that harbors an enormous central black hole
17 billion times more massive than the sun. Another research group spotted a

The report is preliminary, but shows the potential of using the protein and
magnetic fields to stimulate neurons, says Mu-ming Poo, director of the
Institute of Neuroscience at the Chinese Academy of Sciences in Shanghai.
But he and other researchers are critical that the paper does not discuss
how the protein can sense magnetic fields. James Chou, a biological chemist
at Harvard Medical School in Boston, Massachusetts, says that the work
offers no reasonable explanation — or even speculation.

In principle should be doable. However i has not seen a report on animal

It's been tried to culture mangetic nanoparticles with cells and get NPs
internalized. These NPs can be pulled with an external magnetic field to
migrate inside cells and become aggregated. Authors claims that this may be
useful for destructing tumor cells.
I can imagine there are many problems you need to solve in doing animal

转华人科学网。http://www.sciencenets.com/thread-1618-1-1.html
谢灿的文章《A magnetic protein biocompass》终于在《Nature Material》上发表了
,首先恭喜一下作者的文章发表。这也意味着,我们首次有机会比对谢灿与张生家的文
章,对两人关于“抢发”文章的争议做出有一个客观评价。
首先,我来总结并点评一下谢灿的文章所描述的研究成果。
总结:
文章回顾了目前已经提出的动物利用磁场定位的机理。第一,光感蛋白Cryptochromes
(Cry)可以在光线刺激下对地磁场产生反应,而缺失这个蛋白的果蝇会失去磁感应的
能力,因此Cry被认为对动物磁感应起重要作用。但是Cry本身不具备磁极性,因此不具
备指南针的功能。第二,由动物体内具有磁性的矿物质所形成“magnetite”被认为是
另一个磁感应的机制,这些磁性矿物质已经在多种动物的器官中被发现,但是有研究指
出这些矿物质与磁感应无关。
基于以上两点,谢灿在文章中提出一个猜想——应该存在一个具有磁性的蛋白,能与
Cry结合,并且具有磁受体的功能;谢灿将这个假设中的... 阅读全帖

What is a rhabdoid tumor?

A rhabdoid tumor is a rare and highly malignant tumor of childhood, first
described in 1978. These tumors were initially considered an aggressive
variant of Wilms' tumor of the kidney, however, with newer diagnostic
techniques, these tumors are believed to represent a distinct entity. Since
that time, there have been fewer than 50 cases reported, although it is
likely that some cases previously identified as medulloblastoma or as
primitive neuroectodermal tumo... 阅读全帖

华裔第二代亲述:这就是我们一家的真实美国生活
文章来源: 知乎 于 2015-04-27 09:28:37 -
华裔美国人,这个听起来很是熟悉亲近的群体,却往往是我们最缺乏了解的,出生在美
国并且长大的华人真实的生活情况是怎样的。他们的身份、教育、朋友圈、语言、经济
、家庭、包括和父母的关系是怎样的呢?让我们一起来看看一个在美国土生土长的华裔
青年的自述吧!
一位名为Brain的华裔讲述了自己的真实生活。Brain称,先来看一些有意思的东西
Chinese American Humor / What Kind of Asian Are You??Brain称,不确定提问者
想要怎样的答案,但可以来说说他的生活还有朋友。以下为Brain的文章。
关于身份
如果有人问起,我会回答我是亚裔美国人,如果继续追问,我会答是华裔。很少人会回
答“华裔美国人”。很少人这么说,所以我觉得这个词念起来怪怪的。也很少人会回答
“美国出生的中国人”,在中国土生土长的人倒是常用这个词形容我来着。
我和朋友们认为我们是亚裔美国人主要是因为所受的教育。从幼儿园起,学校就有不同
的种族分类:美国白人,美国黑人,拉美... 阅读全帖

谢谢您的回答,还有几个问题。
fuller整个学校不就是magnet学校吗? 您说的那些不是magnet的学生是怎么进来的?
Magnet是不是抽签决定的? 那就是说所有的人的概率一样了? 那老黑也应该不少啊?

你误会了,Magnet 学校里有一部分就是划区进去的,住附近的孩子,你去那几个学校
看看就知道了,都在烂区。当初县里故意把Magnet Program 放在烂校,是希望带动那
些孩子,还有就是县里有规定,一所学校里吃免费午餐的不能太多。
Fuller,Ligon,Enloe 都是AG 的,学生要考试在95% 以上才有资格抽,老黑几乎没有
。有的Magnet 不要考试,但是也要网上申请,估计老黑懒得申请吧。
