Was it the ultimate adventure or an audacious act of disrespect that should be punished by law? An Internet sensation was touched off this week by Russian photographer Vadim Makhorov and a group of his friends -- the group ignored regulations prohibiting the public from climbing on the Pyramids at Giza, Egypt, and came away with spectacular photos. The images from Makhorov and another photographer, Vitaliy Raskalov, were taken on top of the Pyramids from positions that avoided detection by guards. The photos have incited reactions ranging from envy and awe to indignation and concern for the preservation of the ancient wonders.Russian photographer caused sensation with pictures from top of the PyramidVadim Makhorov explains how and why he did itMakhorov: "I would like to apologize for this ascension."

question:
Archaeologists say they have unearthed the oldest human footprints ever found in North America. The impressions were discovered buried at a shoreline at an archaeological dig site on Calvert Island, British Columbia in Canada. Charcoal in the prints has been radiocarbon dated, giving them an age of 13,200 years old. The finding was made by the Hakai Institute and the University of Victoria, both in British Columbia. Archaeologists Dr Daryl Fedje and Dr Duncan McLaren excavated an area below the high tide line, and found dozens of human footprints that had remained intact in clay. An ancient skeleton found nearly 20 years ago in a river in Washington is related to Native Americans, says a DNA study that could help resolve a long-running dispute over its ancestry.Human footprints were found preserved on Calvert Island in CanadaThey were radiocarbon dated to a remarkable 13,200 years oldIf confirmed they would be the oldest human footprints in North AmericaDiscovery also suggests people once migrated down the coast 
 Question:'There's no way to get to _ other than watercraft, and that applies to 13,000 years ago as it does today,' Dr McLaren said.

question:
London (CNN) -- Cyber security is big news right now. It seems a new high-profile breach is reported almost daily and yet this represents only the very tip of the iceberg. Backed by a highly organized black market worth billions of dollars, cybercrime has grown exponentially in scale and sophistication in recent years. In the face of this mounting threat, government and industry are manning the defenses. But finding the right people to protect some of our most valuable data isn't straightforward and requires a new approach. Over the past three years I have competed in a unique set of security games, backed by UK government, industry, academics and professional bodies, known as the Cyber Security Challenge. This aims to find talented amateurs by testing their skills with realistic competitions.Stephen Miller is the reigning UK cyber security championMiller: Cybercrime has grown exponentially in scale and sophistication in recent yearsCybercrime is backed by a highly organized black market and is worth billions of dollarsCyber security is often regarded as hobby for young people rather than "genuine" career 
 Question:In my time playing the Challenge I have come face to face (or face to screen) with many dangerous viruses and computer code, and defended networks from simulated live-hacking attempts carried out by the _'s leading cyber defense experts.
answer:

UK
