At first, British photographer Martin Usborne just wanted to do some reporting on people who leave their dogs locked up in cars. But as he went around scouring parking lots, “making barking noises to try and awaken sleeping dogs that were not actually there,” his project took on a new artistic direction. “The Silence of Dogs in Cars” was inspired by a “childhood memory of waiting in a car whilst his parents were shopping in a supermarket, and the youthful fear that they would not return.”

Two baby orangutans play with each other at the wildlife department in Kuala Lumpur, Malayasia, October 19, 2015.

In this March 31, 2019 photo, an Egyptian student borrows a Bedouin wedding dress to pose for a photograph with Bedouin men from the Hamada tribe, in Wadi Sahw, Abu Zenima, in South Sinai, Egypt. Four Bedouin women are for the first time leading tours in Egypt’s Sinai Peninsula, breaking new ground in their deeply conservative community, where women almost never work outside the home or interact with outsiders. The tourists can only be women, and the tours can’t go overnight. Each day before the sun sets, the group returns to the Hamada’s home village in Wadi Sahu, a narrow desert valley.

A young bull flees from a Brazilian vaqueiro, or cowboy, competing in the “Pega de Boi” (Ox Catch) tournament in Cabrobo, Pernambuco State, Brazil, on September 4, 2022. The riders compete in pairs to retrieve a cord from a bull which has been released and runs away from them and they are timed on how quickly they can return with the cord.

Axel, a research prototype rover for exploring the Moon, Mars and other planets, is remotely driven over rocks as engineers from Jet Propulsion (JPL) and grad students from Caltech (California Institute of Technology) demonstrate its mobile over the steep and rocky grounds of the JPL Mars Yard on January 14, 2009 in Pasadena, California.
