(HealthNewsDigest.com) – Oil shale is a fine-grained sedimentary rock that contains significant amounts of kerogen, a solid mixture of organic chemical compounds that can be converted into synthetic liquid fuel similar to oil, or into shale gas similar to petroleum-derived natural gas. Geologists believe there is more oil shale out there in the rocks of the world—three trillion barrels worth of fuel—than there is oil in existing reserves globally.

(HealthNewsDigest.com) – Sunspots are storms on the sun’s surface that are marked by intense magnetic activity and play host to solar flares and hot gassy ejections from the sun’s corona. Scientists believe that the number of spots on the sun cycles over time, reaching a peak—the so-called Solar Maximum—every 11 years or so. Some studies indicate that sunspot activity overall has doubled in the last century. The apparent result down here on Earth is that the sun glows brighter by about 0.1 percent now than it did 100 years ago.
