POPSBiochemists Manipulate Fruit Flavor Enzymes "Genetic engineering/modification (GM) of green leaf volatile production holds significant potential towards formulating environmentally friendly pest-control strategies. It also has important implications for manipulating food flavor," said Raman, the senior author. "For example, the aroma of virgin olive oil stems from the volatiles synthesized by olives. By modifying the activity of enzymes that generate these substances, it may be possible to alter the flavor of the resulting oils." According to Raman, "Our work shows how you can convert one enzyme to another and, more importantly, provides the needed information for modifying the GLV production in plants." The scientists made 3-D images of the enzymes, which allowed them to make a small, but specific, genetic change in AOS, leading to the generation of HPL.

POPSWhat Is Economics? Exchange is the trading of goods for money or for other goods. A market is any mechanism for buyers and sellers to exchange goods. A free market is a market in which buyers and sellers are generally free to decide what to exchange and under what terms. Money is anything generally accepted as a medium of exchange and thus useful for storing or measuring economic value. The price of a good is the amount of economic value that must be exchanged to acquire it. Demand is willingness and ability to buy. Supply is availability and proffer for sale. The scarcity of a good is the excess of its demand over its supply, and in a free market is measured by price.

POPSThe Male Brain, Explained "We have been assuming that the ways in which emotions are organized in the brain are essentially similar in men and women," but they aren't. Parts of the limbic cortex, which is involved in emotional responses, are smaller in men than in women. Additionally, scientists at McMaster University have found that guys have a smaller density of neurons in areas of the temporal lobe that deal with language processing. Appreciate his naturally upbeat nature Does he seem to be "up" most of the time? It's not your imagination: Male brains produce 52 percent more serotonin (the chemical that influences mood) than female brains, according to a study done at McGill University. And studies show that fewer men than women suffer from depression. Remember his brain is his largest sex organ The preoptic area of the hypothalamus is greater in volume, in cross-sectional area and in the number of cells. This area of the hypothalamus is in charge of mating behavior.

POPSStem cells could allow 'blood farms' One of the issues recently has been the shelf life of blood, where the rotation principle-first in first out can leave blood 'stale' and unsafe. There is also the fact that the contributions cannot meet the demand, and the increase in surgery that requires large volumes of blood. Transplant, and heart surgery being prime examples. They have been searching for a means of producing blood artificially, but the prospect of using stem cells, makes it more likely to be a reality. One of the most important aspects is that the red cells have no nucleus, so no nucleic DNA. A fact that can relieve many ethical, and practical problems.

POPSWhat is Aquaculture? Our oceans simply cannot yield sufficient quantities of fresh fish and seafood to produce enough viable protein for the Earth's population. That poses a dilemna for Fishermen, however, for a large majority of the world, without underwater agriculture, they would simply go hungry...or die.

POPSIsrael Will Act to Prevent a Nuclear Iran Iraq would become increasingly destabilized and the existence of the state of Israel will be directly threatened. Consider that, for many years, Iran has made no secret of its dubious long-term intentions. Israel's destruction has long been its fundamental objective. The multi-year international crisis with Iran is nearing its conclusion. Several months from now, Iran will have successfully achieved the capability to produce a nuclear weapon. Sadly, international diplomacy and an ineffective United Nations will not deter Iran from its nuclear ambition. The result is that the world is well on the path to another international military confrontation. Indeed, the ongoing threats from Iranian President Mahmoud Ahmadinejad appear to leave Israel very little choice. In the next six months, Israel will act to prevent a nuclear Iran.

POPSSummit targets world water issues The U.S. is sending millions every year to developing countries in food and medical supplies. It seems it would be more beneficial to build wastewater treatment plants to produce water for farming. Currently 85% of of cities in developing nations discharge water without any treatment and many people are using this water to grow food crops. The situation is getting worse as more and more people move to urban areas. This creates a higher demand for farmers to produce more food and with clean water becoming more scarce the problem just becomes more compounded.

POPSIce Volcanoes of Titan May Habor Life For almost thirty years, scientists have known that complex carbon compounds called tholins exist on comets and in the atmospheres of the outer planets. Theoretically, tholins might interact with water in a process called hydrolysis to produce complex molecules similar to those found on the early Earth. Could tholins formed in Titan's atmosphere react with liquid water temporarily exposed by meteor impacts or ice volcanoes to produce potentially prebiotic complex organic molecules — before the water freezes? Laboratory research by Catherine Neish, a graduate student working on her doctorate in planetary science at the University of Arizona, suggests, not without controversy, however, that, over a period of days, compounds similar to tholins can be react with water at near-freezing temperatures.

POPSCluebat Applied to the AGW Again... Content Warning, but excellent Fisking of the AGW nonsense. A Sampling All traces of the Kiffian vanish abruptly around 8,000 years ago, when the Sahara became very dry for a thousand years. They must not have listened to Ugh Gore’s dire predictions when he chiseled out his rockumentary “An Inconvenient Twooth: How Woolly Mammoth Drivers Are Killing The Planet!”. The fools. Poor, ignorant fools.

POPSBack to the Future: It's the Cold War Again No one really believes that the US is deploying these missile interceptor systems near Russia as a deterrent against terrorists or "rogue" nations. They are intended for Russia and because Russia's capacity to produce nuclear missiles is substantial, the factory orders in the US for these systems can be ongoing for some time. Can you hear the cash register ring? The tragedy is that it is is reigniting the Cold War all over again with all its tensions and potential for nuclear weapon exchanges and, of course, massive profits for military industries who will "need" to incessantly develop countermeasures to countermeasures.
