Fountains of Life Found at the Bottom of the Dead Sea

For years, ripples at the surface of the Dead Sea hinted there was something mysterious going on beneath its salt-laden waters. But in a lake where accidentally swallowing the water while diving could lead to near-instant asphyxiation, no one was in a hurry to find out what it might be.This year, some intrepid divers changed that, stumbling onto a geological and biological treasure and capturing it on video...

Holding molecules together - van der Waals forces

A while back, I did a post for Chemistry week about hydrogen bonds. In it, I mentioned why I find intramolecular forces so fascinating; they are interactions on such a tiny scale that hold together everything from small molecules like water to massive molecules like the enzymes and multi-enzyme complexes that I study.The hydrogen-bond post seems to pick up a fair amount of visitors each month, and I like to think it has been a useful post for those studying Chemistry for school, or trying to remember their schoolwork at university level...

October 9, 1963: Vajont

" Know, that mountain - it will not stand still. Believe me it´s a troublemaker - you can ask whoever you will. "" La ballata di Longarone ", by Beppe Chierici 1969The valley of Vajont (also Vaiont ) is characterized in the upper part by a large catchment area, smoothed by ancient glacal activity, and a narrow gorge eroded by the river Vajont in the lower part.This geomorphology and the nearby industries made this valley a perfect site for a dam and a hydroelectric power station.Construction of the Vajont dam started in 1956 and was completed in 1960, at this time it was the highest double-curvature arch dam in the world - rising 261.6 meter above the valley floor it was 190m broad across the top, with a capacity of 150 to 168 million cubic meter of water...
