Understanding Time and Rock Units in Geology Geologists use three different units to help in their study of the history of the earth. Time units represent the continuous flow of time through geologic history, rock units represent the different lithologies found across the globe, and time-rock units represent all the rocks formed worldwide during a specific period of geologic time. This week we will examine these units and how they relate to each other. geology • geophysics • earth science • stratigraphy • time

There's a little black spot on the sun today... On June 8, Venus will pass in front of the Sun as seen from Earth. It might not sound like much, but the last time this happened was in 1882. In fact, Venus transits the Sun only 13 or 14 times every 1,000 years. It does, however tend to do it in pairs, separated by a period of 8 years. This transit of the sun by Venus will be repeated in 2012. there's a little black spot on the sun today..." • gregg m. pasterick • amateur astronomy • stars • constellations
Alien call I. First contact will probably - if it ever takes place - not be face to face, instead, a distant call may be radioed purposefully or not.

The Crystal Spheres (Discussion Article) A growing body of scientific evidence tells us that the universe should be teeming with life, but when we point our radio telescopes to the stars we find nothing. Known as the Fermi Paradox or The Great Silence, this fruitless search is puzzling.

The Morphology of Red Blood Cells an Etiology of Tissue Hypoxia? Inflexible red blood cells could be one the contributing factor in restriction of blood flow in the micro-vascular system. The other is vasoconstriction. Normally, the red blood cells are disc shaped and quite flexible. In the case that the red blood cells are not flexable - the pateint is at risk for reduced blood flow and all of the ramifactions that pertain. morphology • red blood cells • chronic fatigue syndrome • myalgic encephalomyelitis • micro-vascular system |
