Samsung hits Apple with 20% price hike: report (ZZ)
Samsung Electronics , the world's largest technology firm by revenue,
raised the price of mobile processor supplied to Apple Inc. AAPL +0.90% by
20% recently, Chosun Ilbo reported Monday, citing a person familiar with
negotiations between the two tech giants.
"Samsung Electronics recently asked Apple for a significant price raise in (
the mobile processor known as) application processor," the person was quoted
as saying in the report. "Apple first disapproved it, but finding no
replacement supplier, it accepted the (increase.)"
The two firms have started to reflect the new supply price recently, the
report added, citing the same person.
According to the report, Apple buys all APs used for production of iPhone
and iPad from Samsung Electronics with the volume estimated to be 130
million units last year and more than 200 million units this year.
Samsung Electronics has a long-term contract to supply APs to Apple until
2014, the report added.
Samsung Electronics and Apple's South Korea office declined to comment on
the report.

那个美女科学家怎么吧Npas4基因从小老鼠身上拿掉？不是生物的，求科普! xiexie
小老鼠身上那么多细胞，怎么吧这个基因单独去除呢？

看来打官司收到的1B就这么又吐回去了
只是便宜了那帮律师老爷

先用同源重组技术把小鼠胚胎干细胞DNA里面的某个基因敲除，然后再注射到
blastocyst里面，这个东西发育成胚胎，长成嵌合体老鼠，因为blastocyst里面只有一
部分细胞来源于胚胎干细胞，所以只有部分细胞是基因敲除的。如果生殖系统恰好也是
基因敲除的，通过杂交就可以得到基因敲除的老鼠。整个过程费时费力费钱，根据运气
大概1-2年能得到最终需要的老鼠。
前两天有个RIKEN的来做报告，说他们觉得这个过程太慢了，想直接用胚胎干细胞发育
成blastocyst，这样就省去了嵌合体老鼠这一步。

看来工作量是很大，这样那篇文章中的老鼠间的对比似乎不太合理，首先是不同的老鼠
，另外如果吧其他的基因拿掉，是不是也会出现这种情况呢。
