Bomb threat forces evacuation of Apple's Irish facilities

A bomb threat ultimately determined to be fake forced the evacuation of Apple's facilities around Cork, including about 4,000 workers in Holyhill, and 800 more at Lavitt's Quay. Cork is home to the only factory owned by Apple itself, which assembles the iMac.

The company does occasionally receive bomb threats at its stores, but typically doesn't have to deal with them at any of its corporate offices in places like Cork, Cupertino or Austin.

Future iOS devices could make use of Li-Fi

Code in recent versions of iOS make reference to Li-Fi, a potential replacement or supplement for Wi-Fi based on visible light. In theory, Li-Fi can deliver bandwidth up to 224 gigabits per second.

Apple batteries may use cobalt mined with child labor

A report from Amnesty International and Afrewatch noted that children as young as seven are mining cobalt that ultimately makes it into the batteries of major car and electronics companies, such as Apple, Samsung, Microsoft, and Daimler. Traders are said to buy the cobalt from smaller producers and sell it to Congo Dongfang Mining, which then sells it to battery makers in China and South Korea.

Apple defended itself, claiming it never tolerates underage labor, in spite of regular incidents with Chinese suppliers, and is "evaluating dozens of different materials, including cobalt, in order to identify labour and environmental risks as well as opportunities for Apple to bring about effective, scalable and sustainable change."
