“These are the stunning images of some of Americas most breathtaking churches – all of which are abandoned. Matthew Christopher travels around the United States taking shots of its most beautiful decaying wonders. He shot those in his churches series in Philadelphia, Pennsylvania, where he works as a photographer and lecturer. Matthew’s fascination with such abandoned spaces started when he was a child when he enjoyed looking at artwork set in buildings that have since decayed”. – Caters News.

Guadalajara-based artist Gonzalo Lebrija created a public art installation in the parking lot (1430 Delgany Street, Denver, CO 80202) across from the Museum of Contemporary Art Denver (MCA Denver) in the summer of 2010. The installation, entitled History of Suspended Time: Monument for the Impossible, was developed as a dual collaboration with MCA Denver's museum-wide exhibition, Energy Effects: Art & Artifacts from the Landscape of Glorious Excess, as well as Denver's inaugural 2010 Biennial of the Americas, an international event that celebrated the culture, ideas and people of the Western Hemisphere.

Hornets are insects that are the largest eusocial wasps. Some species can reach up to 5.5 cm (2.2 in) in length. The true hornets make up the genus Vespa and are distinguished from other vespines by the width of the vertex (part of the head behind the eyes), which is proportionally larger in Vespa and by the anteriorly rounded gasters (the section of the abdomen behind the wasp waist). The best known species is the European hornet (Vespa crabro), about 2–3.5 cm in length, widely distributed throughout Europe, Russia, North America and Northeast Asia.

A man holds up for a picture a one hundred trillion Zimbabwean dollars note inside a shop in Harare, Zimbawe, June 12, 2015. Hyperinflation in Zimbabwe was a period of currency instability that began in the late 1990s shortly after the confiscation of private farms from landowners, towards the end of Zimbabwean involvement in the Second Congo War. During the height of inflation from 2008 to 2009, it was difficult to measure Zimbabwe's hyperinflation because the government of Zimbabwe stopped filing official inflation statistics. However, Zimbabwe's peak month of inflation is estimated at 79.6 billion percent in mid-November 2008. (Photo by Philimon Bulawayo/Reuters)

For her series “Japanese Whispers”, Belgian photographer Zaza Bertrand headed inside the intimate world of rabuhos – Japanese love hotels. Love hotels became popular in Japan from the 1960s onwards, due to a lack of privacy in many family homes. There are now around 37,000 of these hotels in Japan, allowing short daytime “rests” or overnight stays. (Photo by Zaza Bertrand/The Guardian)

Plaster cast moulds of victims of the Mount Vesuvius eruption lie on a display table in a laboratory at Pompeii October 13, 2015. An expert team made up of archaeologists, radiologists, orthodontists and anthropologists began on September 2015 to use CAT scan technology (computerised axial tomography) to peer inside the plaster cast moulds of Pompeii's victims, in a study that has added more detail to previous findings. A 16-layer scan had to be used in order to penetrate the hardened plaster but the results showed up impressive skeletal remains and near perfect teeth. (Photo by Alessandro Bianchi/Reuters)
