A prisoner from the Pedrinhas prison is carried to receive medical help after he was injured during a fight between rival gangs inside the jail, in Sao Luiz, capital of Maranhao state, January 8, 2014. The recent posting on a major Brazilian news website of a video filmed last December 17 by Pedrinhas prisoners of the decapitated and tortured bodies of rival inmates inside the jail has highlighted some of the problems present in the country's prison system which houses nearly twice as many prisoners as its capacity, according to official statistics.

According to the film, Guetta was first introduced to street art by his cousin, the French street artist, Invader”. – Wikipedia

Computer Inc. (Asus) unveiled the Zenbook, the new super-thin laptops. Encased in brushed steel, the Zenbook feels solid, yet light. “The super-thin laptop’s $999 configuration, which includes 4 GB of 133MHz DDR 3 RAM, a 128 GB SATA Solid State Drive (SSD) and two USB 3.0 ports, is $200 cheaper than a similarly configured “competitor” (read: MacBook Air). You can by a MacBook Air for $999 with the same Intel Core i5 CPU — but with only half the memory and storage space. Zenbook would get 7 hours of battery life (roughly 3.4 hours of streaming video and 3.25 hours of gameplay) and could remain in standby for up to two weeks”.

Demonstrators take part in a mass “face-sitting protest” outside the Houses of Parliament in central London on December 12, 2014, as they protest against changes to p*rnography regulations. An amendment to the 2003 Communities Act applies the same strict rules to p*rn bought online as those included in the guidelines set out by the British Board of Film Censors for DVDs. The new laws ban films that feature s*x acts, such as spanking, caning, strangulation, aggressive whipping, humiliation, and face-sitting. Ministers say the rules have been brought in to protect s*x workers. But campaigners say it is an attempt to censor and control the internet. Paid-for videos shot overseas and viewed online in the UK are not affected by the new rules, which were introduced on December 2, 2014. (Photo by Leon Neal/AFP Photo)

A cenote is a natural phenomenon, a sinkhole in the Earth’s surface. The Yucatan Peninsula in Mexico has an estimated 7,000 cenotes because it is primarily made up of porous limestone. For millions of years, rainfall slowly ate away at the limestone and a huge system of underground caves and caverns was formed. Many filled with water from rain or from the underground water table. When the roof of a water filled cave collapses, a cenote is born. The water found in a cenote may be fresh water, salt water, or both. Structurally it may be completely open, like a lake, almost completely closed with just a small opening at the top, or somewhere in between.
