Why some researchers suggest lightning is linked to headaches and migraines
By: Penne Cole
Discovery News reports that researchers at the University of Cincinnati have found a potential link between lightning and headaches. The paper, published in the January 24, 2013, online edition of the Cephalagia journal is the first to find a tie between lightning and headaches, specifically...
How coral reefs use symbiosis
By: Jose Juan Gutierrez
Coral reefs are amongst the most diverse ecosystems in the world. Coral reefs comprise less than 1% of the world's oceans, yet, they are the habitat of approximately one quarter of the Earth's marine species. Coral reefs are very complex marine ecosystems, comprising shading areas...
How minerals are identified
By: Steven J. Wamback
Minerals are the “stuff” of which all rocks are made. Whether Igneous, Metamorphic, or Sedimentary, all rocks are composed of assorted sizes and unique combinations of minerals. Every rock tells a story. Geologists are scientists who have learned to read and share the stories...

No day at the beach is probably a great way to describe the City of Fairbanks, Alaska. Take the year 2009 as an example, and it is a good one because the temperature profile for the United States' coldest city in that year is quite...
The coldest town on earth
By: Dr Pandula Siribaddana
For many, cold winter weather is something that usually does not fall below 30 or -14 degrees Fahrenheit. Some may experience much colder winter weather, with temperatures falling to even -4 to -20 degrees Fahrenheit. Even in such instances, the extra cold weather might not...

The German ship Meteor accomplished a three-year mission of measuring the depths of the South Atlantic Ocean in 1927. Their assumption was that the level of the ocean was uniform, and so depth measured only one thing-how deep the ocean floor was from "sea level...

There are some very key items that go into the soil that everyone walks on. The first thing, what is soil made from. Soil is actually broken up rock sediments and decomposed plants and animals. But what gives soil its texture? That also comes from...

The thermohaline circulation (Great Ocean Conveyor) in the ocean is the flow of surface and deep ocean water currents driven by temperature and density differences. The density of sea water depends on variations in temperature and salinity. Fresh water fluxes coming from rain, ice-melt and...
Symbiosis between coral reefs and algae
By: Jose Juan Gutierrez
Coral reefs are sea water structures made of calcium carbonate (CaCO3) secreted by living organisms. Thousands of organisms thrive in coral reef ecosystems; however, only a small fraction manufactures the limestone required to build coral reefs. Stony (hermatypic) corals are one type of corals responsible...

Clastic sedimentary rocks are composed of other rocks that have broken down or been eroded away. This means that they are fragments of “clasts” of other previously existing rocks. For the most part, that means they are from either igneous, metamorphic, or sedimentary rocks...
