Scientists Accidentally Discover Efficient Process to Turn CO2 Into Ethanol Scientists at the Oak Ridge National Laboratory in Tennessee have discovered a chemical reaction to turn CO2 into ethanol, potentially creating a new technology to help avert climate change. Their findings were published in the journal ChemistrySelect. [Go here for a new in-depth interview about the findings with one of the lead researchers.]
Chaos theory A double rod pendulum animation showing chaotic behavior. Starting the pendulum from a slightly different initial condition would result in a completely different trajectory. The double rod pendulum is one of the simplest dynamical systems that has chaotic solutions. Chaos: When the present determines the future, but the approximate present does not approximately determine the future. Chaotic behavior can be observed in many natural systems, such as weather and climate. This behavior can be studied through analysis of a chaotic mathematical model, or through analytical techniques such as recurrence plots and Poincaré maps. Introduction
Dream Dreams mainly occur in the rapid-eye movement (REM) stage of sleep—when brain activity is high and resembles that of being awake. REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However, these dreams tend to be much less vivid or memorable.

Scientists Uncover How Our Brains Recognize Faces GettyAlfred Pasieka/Science Photo Library When you see a face, what happens in your brain? How do your neurons process facial features to recognize a person you know? Thanks to a group of researchers at Caltech, we may finally have the answer. Doris Tsao Advertisement - Continue Reading Below Pharmacognosy Pharmacognosy is the study of medicines derived from natural sources. The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical, chemical, biochemical and biological properties of drugs, drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources." It is also defined as the study of crude drugs. Introduction
3 Dividend Stocks to Buy With Indestructible Payouts of 7%-Plus Dividend stocks are all the rage now, for better or for worse, because bond yields have effectively dried up as the Federal Reserve kept interest rates at record lows. I’ve been of mixed feelings about this trend, because the chase for yield has led income investors away from the relative safety of bonds and into dividend stocks, which do carry more risk. Thus, as more and more money flows into dividend stocks, they start to get stretched as far as valuation is concerned. When it comes to stocks to buy, jumping in simply for the dividend isn’t a great idea. That’s because, should the valuations of these dividend stocks contract back towards the mean, the loss will be in excess of the dividends paid out over several years. 9 Shiny New Dividend Stocks You Can Trust in the Long Run So I’m trying to find options that are a bit less vulnerable to that kind of price contraction, while also offering a 7% yield or higher to offset some of the existing risk.
