Saudi Arabia is mourning its longtime monarch today. King Abdullah died at the age of 90, passing the leadership title to his 79-year-old brother Salman. The Kingdom is nearing the end of the second generation of male children of the country’s founder, Abdul Aziz, raising questions of who will take over leadership in coming years.

The company, run by 29-year-old founder Aaron Levie, priced its initial public offering shares at $14, valuing the company at about $1.67 billion.

2. Liberia gets its first shipment of Ebola vaccines.

An experimental Ebola vaccine, manufactured by GlaxoSmithKline (GSK), is finally making its way to Liberia. The pharmaceutical maker is hoping to enroll 30,000 people in its first large-scale trials of the vaccine, which was developed with unprecedented speed. However, the rapid decline in Ebola cases in the country will make it difficult to determine the antidote’s efficacy. Liberia’s Ebola infection rate dropped to only eight cases last week from a high of 300 a week in September, according to the World Health Organization.

5. Uber agrees to play by Delhi’s rules.

The ride-sharing company will once again start up service in Delhi after Uber was banned a month ago after a driver allegedly raped a passenger.

The company will have to paint its cars white and apply for a radio taxi license, even though it says it “will remain a technology company and aggregator.”
