Apple had third parties audit all its mineral suppliers to be sure none are using their profits to support armed conflicts. Last year, there were five companies who refused the audits and all were dropped from Apple’s list of suppliers.

The iPhone maker regularly tests to be sure the materials that make its computers and accessories are sourced responsibly.

With the incredible success of the App Store, sometimes it’s easy to forgot that there are still many, many countries the world over that don’t have access to it yet. That number has been reduced today, however, as Apple brings its mobile marketplace to another 32 countries, bringing the total number of countries with access to the App Store to 155.

We’ve seen some truly great accessories for the iPhone this year and the SkyLight should should certainly be counted among them. The SkyLight is a sleek, easy to use adapter that can connect an iPhone to a microscope. In an effort to overcome the global shortage in trained healthcare workers, SkyLight’s creators hope to connect doctors and nurses to patients in developing nations and rural areas.

By holding an iPhone steady over the eyepiece where an image is formed, SkyLight makes it incredibly easy to take pictures and video through the microscope. Once recorded, the pictures and videos are then saved on the phone and can be emailed to doctors, shared on social media sites, or saved for later use. Another interesting idea is that with the use of FaceTime doctors can examine samples remotely and provide immediate feedback.
