World's Most 15 Greatest Living Rocks

1. Great Sphinx of Giza (Egypt): A reclining lion with a human head that stands on the Giza Plateau on the west bank of the Nile, near modern-day Cairo, is the largest monolith statue in the world. Standing 73.5 m (241 ft) long, 6 m (20 ft) wide, and 20 m (65 ft) high, the Great Sphinx of Giza is also the oldest known monumental sculpture, and is commonly believed to have been built by ancient Egyptians in the third millennium BCE. The Great Sphinx faces due east and houses a small temple between its paws.  2. Petra (Jordan): Famously described as "a rose-red city half as old as time" by John William Burgon, UNESCO has described Petra as one of the most precious cultural properties of man's cultural heritage. In 1985, Petrawas designated a World Heritage Site, and recently designated as one of the “new wonders” of the world.

Western diet may raise risk of lung cancer: Study

New Delhi, (IANS): Western diet, often high in salt, sugar and fat, has the potential to raise the risk of cancer in the lungs, finds a study.Previous research has shown the link between poor diet and cancers of organs like the liver and pancreas; thus the long-term impact of diet has been well studied."Lung cancer has not traditionally been thought of as a dietary-related disease," said Ramon Sun, Associate Professor and director of the University of Florida’s Center for Advanced Spatial Biomolecule Research."Diseases like pancreatic cancer or liver cancer, yes. However, when it comes to lung cancer, the idea that diet could play a role is rarely discussed," Sun added.For the study, published in the journal Nature Metabolism, the team focussed on glycogen accumulation -- a storage molecule, made up of glucose, or a simple sugar. It has been found to accumulate at high levels across a variety of cancers and other diseases.Through lab models and computer-guided models of glycogen stores in the lung, the researchers showed that in lung cancer, glycogen acts as an oncogenic metabolite, akin to a "giant lollipop for cancer's sweet tooth."The more glycogen...
