Washington, Oct 21 : A team of scientists have conducted sophisticated mapping of the soil landscape on an extinct American volcano.

The volcano that featured in the research was the Capulin volcano, which formed approximately 62,000 years ago, and is the youngest volcano in the Raton-Clayton Volcanic Field in New Mexico, US.

The cone rises 396 m from the plain, reaching an altitude of 2,495 m above sea level. The base of the volcano is 6.4 km in circumference, and the crater is 126 m deep and 442 m across.

Four different flows of lava can be observed across the monument, indicative of different eruptive events.

Washington, Oct 21 (ANI): The world’s most advanced microscope has been unveiled at the McMaster University in Canada, an instrument so powerful that it can probe the spaces between atoms.

“The resolution of the Titan 80-300 Cubed microscope is remarkable, the equivalent of the Hubble Telescope looking at the atomic level instead of at stars and galaxies,” said Gianluigi Botton, director of the Canadian Centre for Electron Microscopy, professor of Materials Science and Engineering, and the project’s leader.

“With this microscope, we can now easily identify atoms, measure their chemical state and even probe the electrons that bind them together,” he added.

London, Oct. 21 : An Organisation for Economic Co-operation and Development (OECD) report has found that the gap between rich and poor people in the United Kingdom is one of the widest in the developed world.

According to The Telegraph, the gap in earnings widened by 20 per cent between 1985 and 2005.

While both the richest and poorest have been getting richer, the bottom has experienced a growth in earnings three times as large as the top, the OECD report said.

Washington, Oct 21 : Geologists from the University of Utah in the US have identified an amazing concentration of dinosaur footprints that they call “a dinosaur dance floor,” located in a wilderness on the Arizona-Utah border where there was a sandy desert oasis 190 million years ago.

The three-quarter-acre site, which includes rare dinosaur tail-drag marks, provides more evidence that there were wet intervals during the Early Jurassic Period, when the US Southwest was covered with a field of sand dunes larger than the Sahara Desert.

Located within the Vermilion Cliffs National Monument, the “trampled surface” has more than 1,000 and perhaps thousands of dinosaur tracks, averaging a dozen per square yard in places.
