Dead sperm whales are seen washed up on a beach on Texel Island, The Netherlands, January 13, 2016. The five sperm whales that beached on the Dutch lsland of Texel on Tuesday have died overnight, Dutch media reported. It is extremely unusual for so many whales to be in Dutch waters, a spokesman for the Ecomare marine centre told local paper Noordhollands Dagblad. Efforts to get the whales back into open water on Tuesday evening failed and rescuers finally withdrew from the beach at around midnight. The area of beach where the whales are has been closed to the public, to minimise the distress to the animals. (Photo by Cris Toala Olivares/Reuters)

Yang Juan, an employee at Goopal Group, takes a nap in her seat after lunch, in Beijing, China, April 21, 2016. Office workers sleeping on the job is a common sight in China, where a surplus of cheap labour can lead to downtime at work. But in China's technology sector, where business is growing faster than many start-up firms can hire new staff, workers burn the midnight oil to meet deadlines and compete with their rivals. Some companies provide sleeping areas and beds for workers to rest during late nights. (Photo by Jason Lee/Reuters)
