Reuters photographer Bobby Yip took a series of portraits of people taking part in the “Occupy Central” protests in Hong Kong, and asked them why they had joined the demonstrations. China rules Hong Kong under a “one country, two systems” formula that accords the territory limited democracy. Tens of thousands of mostly student protesters are demanding Beijing give them full democracy, with the freedom to nominate election candidates. The unrest is the worst in Hong Kong since China resumed its rule over the former British colony in 1997. (Photo by Carlos Barria/Reuters)

Vardzia is a cave monastery site in southern Georgia, excavated from the slopes of the Erusheti Mountain on the left bank of the Mtkvari River, thirty kilometres from Aspindza. The main period of construction was the second half of the twelfth century. The caves stretch along the cliff for some five hundred metres and in up to nineteen tiers. The Church of the Dormition, dating to the 1180s during the golden age of Tamar and Rustaveli, has an important series of wall paintings. The site was largely abandoned after the Ottoman takeover in the sixteenth century. Now part of a state heritage reserve, the extended area of Vardzia-Khertvisi has been submitted for future inscription on the UNESCO World Heritage List

A greenhouse is a contained quantity of air and light which extends the growing season and enables the thriving of plants otherwise alien to local climate. It creates a bubble of super-nature, where things otherwise impossible become possible. The smell, temperature, humidity and taste of things are significantly different than just outside the thin membrane. It enables us to create different kinds (or quantities) of food, but also to experience different climates and atmospheres. A greenhouse is by definition alien to its site, but creates a significant place in everyday life.

Floralis Genérica is a sculpture made of steel and aluminum located in Plaza de las Naciones Unidas, Avenida Figueroa Alcorta, Buenos Aires, a gift to the city by the Argentine architect Eduardo Catalano. Catalano once said that the flower "is a synthesis of all the flowers and is both a hope that is reborn every day to open." It was created in 2002. The sculpture moves closing its petals in the evening and opening them in the morning, although this mechanism is currently disabled. The sculpture is located in the center of a park of four acres of wooded boundaries, surrounded by paths that get closer and provide different perspectives of the monument, and placed above a reflecting pool, which apart from fulfilling its aesthetic function, protects it. It represents a large flower made of stainless steel with aluminum skeleton and reinforced concrete, which looks at the sky, extending to it its six petals. Weighs eighteen tons and is 23 meters high.
