For decades, researchers have been aware of its potential as a fuel. But the process to produce ethanol inexpensively and efficiently has been elusive -- until now, some scientists say. A fast-growing grass known as switchgrass can be found around the United States, Canada, Central and South America, and parts of Africa. And, if it continues to show the kind of promise it does now, it may be what you use to fuel your car in the next 20 years. So how can grass become fuel? Read the next page to find out about the sunny forecast for switchgrass as an answer to the impending energy crisis. Research into sources for biological fuels -- biofuels -- has included everything from chicken fat to wood chips. But processing most of them yields a low net energy ratio -- the amount of energy each unit puts out isn't much more than the energy put into its production. Cost has also been a problem: Techniques for extracting fuels from plant and animal resources are currently expensive, which would be reflected at the fuel pump.
Being a video game developer allows you to flex your tech skills while earning a nice paycheck. Video Game Developer - Your mother might have told you there was nothing to learn playing video games, but tell that to the folks who make them. More than 42,000 people in 36 states and Puerto Rico are employed by the booming U.S. Employment is up 30 percent since 2009, and the pace is more than 13 times faster than the rest of the labor market. Graphic Designer/Illustrator - Who said doodling can't lead anywhere? The field of graphic design employs about 260,000 people at a median salary of more than $44,000 per year. The top 10 percent of designers earn more than $77,000 per year. Astronomer - Stargazing types could potentially make good money figuring out the nature of the universe. As of 2012, astronomers and physicists earned a median income of $106,000 per year.|Humans have a lot of ways to measure their health. We take stress tests on our hearts. We check our cholesterol. Heck, we can stick a thermometer under our tongue to see if that chill is just a cold room or something more malicious. But those things only give a snapshot of certain systems; it's hard to measure the big picture. And if it's hard for us humans, imagine attempting to measure the health of the world's oceans, which cover 71 percent of Earth's surface, and hold 97 percent of the world's water. While we can learn a thing or two by taking the ocean's temperature, we need more robust systems to determine how the ocean's overall health is faring. The index, a partnership between Conservation International and the National Center for Ecological Analysis & Synthesis (NCEAS) at University of California, Santa Barbara, has a few purposes. Lindsay Mosher, coordinator for the Ocean Health Index, says via email. The OHI calculates an annual global score for ocean health, as well as individual scores for nations on well they're protecting and stewarding their share of ocean waters.
All of a sudden, we're able to see all sorts of things we couldn't spot before. Warm dust. Comets. Planets! Obviously, seeing more stuff is better than seeing less. More infrared lets you see more clearly. Not quite. Remember that seeing in infrared is essentially looking at heat. That means that Hubble, looking in the ultraviolet, visible or even near-infrared range, can actually see some things that Webb won't be able to distinguish, like cold dust or gases. Imagine looking at a closed paper bag. You've got yourself a paper bag there. But if you're able to look at it in infrared light, you would no longer see the paper bag, but rather a cat who is pretty ticked at being chosen to illustrate my clever analogy. Now, it's not that you can see the picture more clearly with infrared, because you can't see the bag. On the other hand, in visible light, you can only see the bag. The thing is, it isn't necessarily "clearer" to see in infrared; it just lets us see different things. We're looking at light emitted in different wavelengths, depending on the object. For the complete picture, we need to see it all.

For those people you intend to invite, a written invitation is always in good taste. Formality isn't obligatory, though. You can send e-mail invitations or make a series of phone calls, instead. If you're working on a tight budget or time is a factor, the important thing is to get the word out. Written or e-mailed invitations have the advantage of being consistent. You won't forget any of the details, and you can add some helpful reference materials like a map to the church or parking recommendations for the reception or after-party. Assist out-of-town visitors -- If guests will be arriving from out of town, provide hotel recommendations and transportation options. Arrange for a christening gown -- This could be a classic white confection you plan to make a family heirloom or a christening gown that's already been in your family for generations. To keep the gown pristine, pack another garment the baby can change into right after the ceremony.|If you are thinking of traveling to Eastern Europe you should consider a trip to the Ukraine.

Such pumps are available at auto supply stores, or often, from the providers of the analysis kits. If it's one that you mail in, it will likely include a small jar or bottle for the sample, along with a label you fill out that tells the lab about the sample. It may also include a separate container into which you can pack the sample for mailing. You then receive the results by mail, e-mail or phone, typically within a few days. For tests that let you read the results at home, (like QMI of Missouri's MotorAnalyzer), you just place a drop of warm motor oil on the supplied test sheets. Then you compare the pattern produced by the oil drop with the patterns shown on the included test analysis guide. If you're a novice, especially, it can be pretty intimidating trying to interpret what those results mean.
