Genes for Face Shape Identified|核磁共振造影

The discovery of five genes involved in facial form could have applications in forensics, according to the authors of a study. Previously, virtually nothing was known about the genes responsible for facial shape in humans. Lead author Manfred Kayser from the Erasmus University Medical Center in Rotterdam, the Netherlands said, "These are exciting first results that mark the beginning of the genetic understanding of human facial morphology. Perhaps someday it will be possible to draw a phantom portrait of a person solely from his or her DNA left behind."

The researchers used magnetic resonance imaging of people's heads together with portrait photographs to map facial landmarks, from which facial distances were estimated.

核磁共振造影（magnetic resonance imaging，简称 MRI），是利用核磁共振原理，依据所释放的能量在物质内部不同结构环境中不同的衰减，通过外加梯度磁场检测所发射出的电磁波，即可得知构成这一物体原子核的位置和种类，据此可以绘制成物体内部的结构图像。

将这种技术用于人体内部结构的成像，就产生出一种革命性的医学诊断工具。快速变化的梯度磁场的应用，大大加快了核磁共振造影的速度，使该技术在临床诊断、科学研究的应用成为现实，极大地推动了医学、神经生理学和认知神经科学的迅速发展。

Apple Takes Revenge

Apple made a radical decision in their new operating system when they chose face over function. Because of their recent squabbles, Google Maps was booted out in favor of a home brewed Maps app in iOS 6, and the results are pretty ugly. Apple has turned its Maps app for iOS 6 into a political football. By punting Google's map data, Apple is putting its own interests before those of its customers. The new operating system snubs Google's clearly superior Maps product for its own inferior one in what appears to be retaliation for Android's perceived infringement on iOS.

Apple is at a crossroads. If it unnecessarily delays the approval of Google Maps for iOS 6, it will be sending a clear message to its customers that it's no longer interested in providing them with the best possible user experience.

苹果的复仇

苹果公司在他们新的操作系统上作了一个彻底的决定，他们选择弃功能而着重面子。由于苹果和 Google 最近的争论，Google地图被逐出了 iOS 6 系统中一项支持苹果自行开发地图的应用程序，而结果相当糟糕。苹果公司已将 iOS 6 系统中所使用的地图应用程序转变为一个争议性的问题。透过踢走 Google 的地图数据，苹果公司把自身的利益看得比消费者还重要。新的操作系统停用了 Google 明显较优的地图产品，而采用了苹果自己较差的产品，这似乎是要报复 Android 被发现侵害了 iOS 的权利。

苹果公司现在正面临抉择。如果他们不必要地延迟批准 iOS 6 系统中所使用的 Google地图，他们就要清楚地告知消费者，他们对于提供用户可能是最棒的使用经验已不再感兴趣。

iOS是由苹果公司开发的操作系统。最初是设计给 iPhone 使用，后来陆续套用到 iPod touch、iPad 以及 Apple TV 产品上。就像苹果的 Mac OS X 操作系统一样，它也是以 Darwin为基础的。原本这个系统名为iPhone OS，直到 2010 年 6 月 7 日才宣布改名为 iOS。iOS的系统架构分为 4 个层次核心操作系统层、核心服务层、媒体层及可轻触层。系统操作占用大概 1 GB 的内存空间。
