Riot police arrest an anti-government protester in Ouagadougou, capital of Burkina Faso, October 30, 2014. Thousands of protesters marched on Burkina Faso's presidential palace after burning the parliament building and ransacking state television offices on Thursday, forcing President Blaise Compaore to scrap a plan to extend his 27-year rule. Emergency services said at least three protesters were shot dead and several others wounded by security forces when the crowd tried to storm the home of Compaore's brother. Security forces also fired live rounds and tear gas at protesters near the presidency in the Ouaga 2000 neighborhood. (Photo by Joe Penney/Reuters)

“Sektor gaza” (Russian: Сектор газа) was a Russian rock band formed on 5 December 1987 in the city of Voronezh, Russia. Despite only semi-officially existing (due to obscene lyrics), the group remains popular in Russia today. The group name was taken from an eponymous industrial district of Voronezh (itself named for high levels of environmental contamination). Their music style could be defined as Russian punk, integrated with elements of different musical genres such as rock, rap, and Russian folk. On 4 July 2000, group leader Yuri “Hoy” Klinskih complained of strong pains in his stomach and the left side of his chest. He suffered heart failure shortly thereafter. Klinskikh died in Voronezh (Russia)at the age of 35. He is buried in the Levoberezhniy Cemetery. The group ceased to exist.

About the music video: The First Chechen War, also known as the War in Chechnya, was a conflict between the Russian Federation and the Chechen Republic of Ichkeria, fought from December 1994 to August 1996. After the initial campaign of 1994 – 1995, culminating in the devastating Battle of Grozny, Russian federal forces attempted to seize control of the mountainous area of Chechnya but were set back by Chechen guerrilla warfare and raids on the flatlands in spite of Russia's overwhelming manpower, weaponry, and air support...

Shepherds lead their sheep through the centre of Madrid, Spain, Sunday, October 25, 2015. Shepherds have guided a flock of 2,000 sheep through Madrid streets in defense of ancient grazing, droving and migration rights increasingly threatened by urban sprawl and modern agricultural practices. Tourists and city-dwellers were surprised to see the capital's traffic cut to permit the ovine parade to bleat bells clanking its way past the city's most emblematic locations.

With its huge eyes, comical name and diminutive size, Mark R. Smith’s image of a baby Hawaiian bobtail squid can’t help but raise a smile. A curiously endearing creature, the cephalopod is just 1.5cm across, its mantle cavity bearing more than a passing resemblance to a rather natty shower cap. But it is also a beautiful example of symbiosis – nature’s version of “I’ll scratch your back if you scratch mine” – for on the underside of the squid is a light organ which houses bioluminescent bacteria. The squid offers the bacteria protection and food, while the bacteria emit a glow – a handy trait that the squid uses to offset its silhouette, helping it to evade predators in the depths below. Mark R. Smith’s entry combines several images of a Hawaiian bobtail squid with different focus lengths to create a final picture with greater depth of field than normal. (Photo by Mark R.

“Microscope images forge an extraordinary bond between science and art, said Hidenao Tsuchiya, Olympus America's Vice President and General Manager for the Scientific Equipment Group. We founded this competition to focus on the fascinating stories coming out of today's life science research laboratories. The thousands of images that people have shared with the competition over the years reflect some of the most exciting work going on in research today – work that can help shed light on the living universe and ultimately save lives. We look at BioScapes and these beautiful images as sources of education and inspiration to us and the world”. – OlympusBioScapes
