Jorge, an immigrant from Mexico, exits a subway station dressed as the Sesame Street character Elmo in Times Square, New York July 30, 2014.

Sesame Workshop, which owns the rights to Big Bird, Ernie and the assorted puppet monsters on the 45-year-old program, said on July 29, 2014 it was drafting plans to stop performers who dress up as the characters from appearing in Times Square, where they pose for photos with tourists and then demand tips.

Brazilian jaguars, imperilled by hunters, ranchers and destruction of their habitat, have learned to survive at least one menace – flooding in the Amazon. They take to the trees. Although they can be six feet long and 200 pounds, the largest South American cats nimbly navigate treetops where they stay from April to July when the rainforest floor is under meters-deep water. Here: A female adult jaguar, which has a cub, growls at the Mamiraua Sustainable Development Reserve in Uarini, Amazonas state, Brazil, June 5, 2017. (Photo by Bruno Kelly/Reuters)

“Solar Impulse is a European long-range solar powered plane project being undertaken by Bertrand Piccard and André Borschberg. The project eventually hopes to succeed in the first circling of the earth with a piloted fixed-wing aircraft using only solar power. The first aircraft, bearing the Swiss aircraft registration code of HB-SIA, is a single-seater, capable of taking off under its own power, and intended to remain airborne up to 36 hours. This aircraft first flew an entire diurnal solar cycle, including nearly 9 hours of night flying, in a 26-hour flight on 7–8 July 2010”. – Wikipedia

“The Naval and Military Club is a gentlemen's club in London, England. It was founded in 1862 because the three then existing military clubs in London – the United Service, the Junior United Service and the Army and Navy – were all full. The membership was long restricted to military officers. This is no longer the case, but it still has a predominantly military and ex-military membership”. – Wikipedia
