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. The rover is capable of descending cliffs or into craters and returning by a cable tethered to its starting point. Development of the Axel rover is a point effort funded by NASA Exploration Systems Mission Directorate (ESMD) and lead by Principal Investigator Issa Newnas and Co-Investigator and Caltech professor of mechanical engineering bio engineering Joel Burdick.

“Cockayne syndrome (also called Weber-Cockayne syndrome, or Neill-Dingwall Syndrome) is a rare autosomal recessive congenital disorder characterized by growth failure, impaired development of the nervous system, abnormal sensitivity to sunlight (photosensitivity), and premature aging. Hearing loss and eye abnormalities (pigmentary retinopathy) are other common features, but problems with any or all of the internal organs are possible. It is associated with a group of disorders called leukodystrophies. The underlying disorder is a defect in a DNA repair mechanism. It is named after English physician Edward Alfred Cockayne (1880–1956)”. – Wikipedia

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.

Most Russians intending to vote for Vladimir Putin in Sunday's election say stability is at the root of their faith in their candidate – though many young voters believe it's time for a change of leader. Putin, 65, is expected to win a fourth term in office with 69 percent of the vote, according to the latest survey by a state-run pollster. Reuters correspondents and photographers who travelled around the country talking to voters ahead of the March 18 election found nothing to contradict expectation of an emphatic Putin victory.

A radiation monitor indicates 114.00 microsieverts per hour near the building housing the plant's No. 4 reactor, center, and an under construction foundation, right, which will store the reactor's melted fuel rods at Tokyo Electric Power Co.'s tsunami-crippled Fukushima Dai-ichi nuclear power plant in Okuma, Fukushima prefecture, Wednesday, March 6, 2013, ahead of the second anniversary of the March 11, 2011 tsunami and earthquake. Some 110,000 people living around the nuclear plant were evacuated after the massive March 11, 2011, earthquake and tsunami knocked out the plant's power and cooling systems, causing meltdowns in three reactors and spewing radiation into the surrounding air, soil and water.

Chief priest Gbenga Saala raises a cutlass to kill a dog during an annual prayer and sacrifice celebration of the iron god Ogun in Abuja, Nigeria, June 23, 2015. Every year worshippers offer a dog as sacrifice to Ogun, a traditional Nigerian deity, in hope of an auspicious year ahead. Taxi drivers, blacksmiths, panel beaters and mechanics – trades that depend on metal for their livelihood – pay homage to Ogun, led by high priest Gbenga Saala. As part of the ceremony, the priest pours the dog’s blood on symbols of these workers’ trade: keys, spanners and other tools piled up in a metal barrel. (Photo by Afolabi Sotunde/Reuters)
