5 great football moments from film, TV
By Courtney Hazlett, NBC News
Football might have its biggest day of the year on Super Bowl Sunday, but thanks to the magic of movie- and television-making, the sport lives on in mythic proportions all year long. Here's a look at some of football's best onscreen moments:
"Clear eyes, full hearts, can't lose," was a phrase that generated?headlines during the 2012 presidential election, but it was actually made famous on the TV series "Friday Night Lights." The phrase was part of one of Coach Taylor's (Kyle Chandler) pep talks. Below, a mash-up of some of Coach's greatest phrases from the show.
Speaking of pep talks, Al Pacino's inspirational speech in "Any Given Sunday" could be to blame for the discomfort found in listening to "real" coaches give their halftime talks. Pacino is passionate, convincing and motivating. If at the end you aren't ready to "fight for every inch," well, maybe inspirational speeches just aren't for you. (Beware, there's some locker-room language in this one).
Less intense and far more amusing is the football scene in "The Wedding Crashers." The highlight is Bradley Cooper (who really became a household name thanks to the film) as Sack Lodge, a slightly creepy, overly competitive boyfriend who puts all his creepy, overly competitive qualities on display in what should be a friendly game of backyard touch football.
Turn back the clock for another backyard football game gone wrong. All Marcia Brady wanted to do on TV classic "The Brady Bunch" was tell the boys dinner was ready, and think about her dreamy date set for Saturday night. But ... OH, MY NOSE!
And since it's Super Bowl weekend, a weekend that's as much about football as it is the economic boost that comes from the big game, it seems fitting to end by saying, "Show me the money!"?
Do you have some great football scenes from film and television that you especially love? Take the discussion on over to Facebook and share them with us.

Fed officials see brighter global economic outlook
WASHINGTON/NEW YORK (Reuters) - Two top Federal Reserve officials painted a picture of cautious optimism on Friday for the U.S. economy in 2013, helped by stronger global growth as the central bank aggressively prints money to curb the nation's lofty rate of unemployment.
The Fed this week decided to keep buying bonds at a $85 billion monthly pace, and hold interest rates near zero until the jobless rate falls to 6.5 percent, so long as inflation does not threaten to rise above a threshold of 2.5 percent.
U.S. unemployment edged up 0.1 percentage point to 7.9 percent in January, and the economy shrank slightly in the final quarter of 2012.
But New York Federal Reserve President William Dudley and St. Louis Fed chief James Bullard, who both voted in favor of the U.S. central bank's policy decision this week, saw reasons to be cheerful about the year ahead.
Their remarks are the first public comments by Fed policy-makers since the central bank issued a statement on Wednesday outlining its decision to keep in place an unprecedented level of monetary stimulus, which has tripled its balance sheet to almost $3 trillion since 2008.
"I think a lot of uncertainties that were around this economy in 2012 have come off the table," Bullard told Bloomberg Television in an interview.
"The (U.S.) election has come off. Some of the fiscal risk that was in the U.S. has come off. The European situation has settled down a lot. China looks like it will have a better year. Emerging markets generally...will have a better year," he said.
U.S. lawmakers on Thursday voted to allow the federal government to keep borrowing money until at least May 19, averting a potential collision with the U.S. debt limit that could have caused the nation to default on its debt obligations.
Politicians had already sidestepped potential tax hikes on all Americans at the start of 2013 by agreeing to raise taxes only on families who make more than $450,000 a year.
SLOWING BOND PURCHASES?
Bullard, who is viewed as a centrist on the Fed's 19-member policy committee, said that continued improvements in the labor market during the course of the year would put the Fed "in a position to slow down or stop the purchases."
A closely watched employment report released by the U.S. government earlier on Friday showed that 157,000 new jobs were created in January, while the previous two months' scale of employment creation was also revised higher. U.S. stocks rallied on the news.
"Things aren't perfect. But things are definitely improving, and that will actually be helpful for the U.S. outlook," Dudley told the New York Bankers Association in a speech that was mostly focused on revamping the wholesale funding market.
"If the rest of the world gets healthier, the demand for U.S. goods and services will increase and that will provide support to our own economy," he said.
With the Fed forecasting unemployment to decline only slowly over the next two years, economists do not expect it to begin raising interest rates until 2015 and see bond purchases continuing for the rest of this year and possibly into 2014.
However, minutes of the Fed's December 11-12 meeting, which were released with a three-week lag, showed that several policymakers wanted to slow or halt the buying well before the end of 2013.
Bullard, who had opposed the third round of bond purchases when it was announced in September, said he voted to back its continuation at the most recent meeting because it was a decision to keep policy steady.
"I felt that was probably the right thing to do at this meeting and so I was in agreement with the chairman and the majority in this case," he said.
However, he made clear that the central bank's policy committee continued to wrestle with quantitative easing.
Nor was there any consensus on providing markets with more clues on when the purchases will end, beyond current Fed guidance that it will look for a substantial improvement in the labor market outlook in weighing when to stop.
"I don't think we have any more agreement among members at this point," he said.
Some Fed officials favor adopting numerical economic thresholds to guide expectations of when buying will end. But Fed-watchers doubt the committee will be able to quickly come to a consensus over this matter, and it may prove impossible.

NASA to Launch World's Largest Solar Sail in 2014
The largest solar sail ever constructed is headed for the launch pad in 2014 on a mission to demonstrate the value of "propellantless propulsion"? the act of using photons from the sun to push a craft through space.
Dubbed Sunjammer, the giant?solar sail measures about 124 feet (38 meters) on a side and boasts a total surface area of nearly 13,000 square feet (1,208 square m, or one-third of an acre). The project is under the wing of NASA's Space Technology Program, within the agency's Office of the Chief Technologist.
NASA has contracted with a team of high-tech "solar sailors" at L'Garde Inc. of Tustin, Calif., to build Sunjammer.
L'Garde is no newcomer to novel space structures. The company has worked with the space agency on several projects, including the creation of inflatable structures for radio frequency antennas and solar arrays. In 1996, the company flew the Inflatable Antenna Experiment (IAE) aboard the space shuttle Endeavour's STS-77 mission. [Photos: Solar Sail Evolution for Space Travel]
Programmatic milestone
"We took the name Sunjammer from an Arthur C. Clarke short story, a fictional yacht race in the heavens using solar sails," said Nathan Barnes, L'Garde's chief operating officer and executive vice president, as well as Sunjammer's project manager. Permission to use the name came from the Clarke estate, he told SPACE.com.
Work on Sunjammer this year includes a programmatic milestone ? a critical design review ? along with a variety of ground demonstration tests and qualification of components, Barnes said. The flight of the solar sail, he said, is set for the end of 2014, to be sent spaceward atop a SpaceX Falcon 9 rocket.
"With this sail, we?re targeting our end goal somewhere in the neighborhood of 1,864,114 miles (3 million kilometers) distance from the Earth," Barnes said.
A number of test objectives are to be checked off within the first couple months of flight, he added. These include deployment of the sail, demonstration of vector control using sail-tipped vanes, navigation with accuracy and, finally, maintenance of the spacecraft's position at a gravitationally stable location called Earth-Sun Lagrange Point 1.
Sunjammer won't be the world's first solar sail mission. NASA launched NanoSail-D, whose sail covered just 100 square feet (9.3 square m), in November 2010. And Japan's Ikaros probe deployed?its solar sail in June 2010, becoming the first craft ever to cruise through space propelled only by sunlight.
Neat, clever, exotic orbits
Sunjammer is potentially applicable to an advanced space weather warning system, which could provide more timely and accurate notice of solar flare activity.
The U.S. National Oceanic and Atmospheric Administration is collaborating with NASA and L?Garde on the upcoming demonstration flight, which will cruise to a spot that provides an interesting view of the sun.
"It will be us flying to a place that a customer actually wants to fly a solar sail to," Barnes said. "There are neat, clever, exotic orbits you can do with the solar sail that would permit viewing different portions of the sun that we can?t normally." [The Sun's Wrath: Worst Solar Storms in History]
One-quarter the size of a football field, Sunjammer will produce a whopping maximum thrust of approximately 0.01 newton, Barnes said ? roughly equivalent to the weight of a sugar packet.
Thinner sail
Kapton is the solar sail material of choice. The mission team worked with chemical company DuPont to produce a special layer of Kapton for Sunjammer just 5 microns thick.
"Thinner is always better," Barnes said.
When collapsed, the Sunjammer solar sail is the size of a dishwasher and weighs just 70 pounds (32 kilograms).
There are a number of control techniques involved in successfully unfurling the sail, said Billy Derbes, L?Garde?s chief engineer for Sunjammer.
"The highest risk is in the deployment," Derbes said. A camera attached to the sail will capture the unfurling process.
Game-changing capabilities
NASA is keen to infuse solar sail technology into other potential game-changing mission capabilities.
Barnes said that possibilities include the collection and removal of orbital debris, deorbiting spent satellites, providing a direct communications link to Earth?s south pole, as well as for deep space propulsion.
Barnes said nongovernment, entertainment-oriented uses of solar sails are also being explored by L?Garde.
"All space travel right now is limited by expendables," Derbes said. "If you show a technology not limited by expendables ? and Kapton is a long-lasting film material ? what new applications will people think up? We?re opening up a whole new kind of thinking about how you do things in space."
'Star Trek' passengers
Also to fly onboard Sunjammer are the cremated remains of individuals, a service provided by Celestis, Inc., an affiliate company of Space Services, Inc., a Houston-based aerospace firm.
Celestis flight capsules and modules will be carried by Sunjammer on its voyage through deep space. Already part of that payload are the ashes of "Star Trek" creator Gene Roddenberry and his wife Majel Barrett Roddenberry, often called the "first lady" of the sci-fi series.
"Celestis is pleased to offer our first-ever Voyager deep space memorial spaceflight aboard the Sunjammer mission," said Celestis CEO Charles Chafer.
"Since 1997, Celestis has conducted a dozen memorial spaceflights, and this solar sail mission will mark our most ambitious flight ever. We are excited to be a part of the Sunjammer team," Chafer told SPACE.com.
'Green' space propulsion
Sunjammer?s success is the key to enabling several science and exploration missions that can only be accomplished with a solar sail, said Les Johnson, deputy manager of the Advanced Concepts Office at NASA's Marshall Space Flight Center in Huntsville, Ala.
Along with better sun-watching and warning tasks, NASA recently studied the use of a solar-sail-propelled spacecraft for visiting multiple near-Earth asteroids (NEAs), Johnson said.
"We found that a Sunjammer-derived sail could visit up to six NEAs within six years of being launched. This would be impossible with chemical rockets and might not be achievable by electric propulsion. And it?s all because the sail uses no propellant ? deriving its thrust from sunlight, making it a very ?green? space propulsion system," he said.
Johnson is co-editor with Jack McDevitt of "Going Interstellar" (Baen Books, 2012), a unique blend of science fact and science-fiction writings on interstellar voyaging.
"For me, I?m most excited about using a solar sail unfurled close to the sun, inside the orbit of Mercury, and using the increased solar pressure there to accelerate a large solar sail to speeds that will allow it to reach well beyond the edge of the solar system and into interstellar space within my lifetime," Johnson said.?
Doing so, Johnson said, "would be the first ?baby step? in a series of increasingly large sails that might one day enable us to reach the stars. This is one of the few ways nature has provided for us to travel between the stars."

Biologistics: How fast do chemical trains move in living cells?
Jan. 31, 2013 ? The rate of chemical processes in cells is dictated by the speed of movement (diffusion) of molecules needed for a given reaction. Using a versatile method developed at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, researchers were able to predict for the first time the diffusion coefficients of all proteins in Escherichia coli. The achievement is important not only for biologists and chemists, but also for... transport companies.
Understanding of chemical foundations of life requires knowledge about the rate of chemical reactions in cells. The rates of these reactions depend on how fast the molecules taking part in reactions move (diffuse) in the cytoplasm. Prof. Robert Ho?yst's research team from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw (IPC PAS) managed to determine -- for the first time -- the diffusion coefficients for virtually all the proteins occurring in Escherichia coli. The method developed by the researchers can also be used for other cells.
The movements of molecules in cells resemble a bit what's going on in railway stations. But the differences are obvious at first glance. "Regular trains leave stations at fixed times, whereas in cells transport processes take place virtually all the time. That's why it doesn't make sense to ask what time does the train with specific molecules leave the station. But it definitely makes sense to ask how fast the train with specific molecules is moving!," explains Prof. Robert Ho?yst (IPC PAS).
Transport efficiency of chemical compounds in cells became inspiring for many transport companies. There's talk of biologistics as modelling vehicle or rail transport by looking up to what's going on inside the cells. Prof. Ho?yst, however, has no illusions about that: "Everyone is delighted, for in cells the transport is so wonderfully resistant to perturbations. They forget, however, that the transport results from random fluctuations, in addition occurring in a small volume, where viscosity depends not only on the medium, but also on the size of the viscosity probe! I wish good luck all those who want to transfer processes occurring in physically so different environment to our roads. Biologistics works excellent, but inside cells only!."
Supported by grants from the National Science Center and the Ministry of Science and Higher Education as well as by programs from the Foundation for Polish Science, the research published in the "Bioinformatics" journal focused on the rate of diffusion of protein molecules in the Escherichia coli cytoplasm.
"The viscosity inside mammalian cells is relatively low, only 60 times higher than that of water. But bacteria are considerably smaller, everything is more crowded. The macroscopic viscosity there is up to 26,000 times higher than that of water. This is really dramatic difference!," concludes Dr Tomasz Kalwarczyk (IPC PAS).
Earlier research of Prof. Ho?yst's team allowed for concluding that viscosity experienced by molecules is not only medium, i.e., solvent dependent, but also depends on the size and shape of molecules. Therefore, in the same medium, molecules differing in shape and size can experience very low viscosity (nanoviscosity) or macroscopic viscosity that is up to several thousand times higher. The previous methods for predicting diffusion coefficients in cytoplasm have not accounted for the effect.
Experimental determination of the diffusion rates of chemical compounds in bacterial cells is both time consuming and difficult. As a result, diffusion coefficients have been measured only for a very limited number of compounds in only some bacterial cells. That's why the researchers from the IPC PAS developed a method for predicting diffusion coefficients for various compounds and media. For that purpose they used their own formulae, accounting for nanoviscosity and macroscopic viscosity, and a few dozens of diffusion coefficients of macromolecules in Escherichia coli taken from the literature. This was a basis for construction of a scale-dependent viscosity reference curve that could be used to determine diffusion coefficients of remaining compounds.
The database constructed at the IPC PAS contains diffusion coefficients for complete proteome of Escherichia coli. It includes over 6000 macromolecules, with about 4300 gene-expressed amino acid chains and their various, often multiple combinations (polymers), created both by the same chains (homomers), and by different amino acids (heteromers).
"Because of easy access to the literature data, we created a database only for molecules occurring in Escherichia coli. Our method could be, however, adapted for virtually any cell and every molecule, for instance for determining diffusion coefficients of sugars in mammalian cells," stresses Dr Marcin Tabaka (IPC PAS).

LG Spirit 4G arrives on MetroPCS, delivers 4.5-inch display and ICS to the budget-minded crowd
We are definitely no strangers to seeing MetroPCS bring well-priced, decently-specced Android handsets to market, and we have a feeling that's something potential and current subscribers certainly appreciate. Because, well, who doesn't like choice? With today's LG Spirit 4G launch, MetroPCS continues to expand its LTE-at-a-bargain ideals, announcing a smartphone that carries some pretty decent specs for being contract-free and costing a mere 269 bucks. Naturally, the 4.5-inch, 960 x 540 display is among the Spirit's main highlights, but there's also an unspecified 1.2GHz, dual-core CPU, a 5-megapixel rear shooter capable of 1080p video, and Ice Cream Sandwich, to boot. The carrier's quick to point out that its newly introduced slab is a follow-up to that LG Motion 4G we saw last year, and that it's compatible with those LTE plans which were unveiled earlier this month. It's worth noting that while the LG Spirit 4G's official MSRP is $269, MetroPCS will have it up for grabs, starting today, at the cheaper price of $199 -- that, of course, after a beloved mail-in rebate and for "a limited time" only. You'll find a couple more press shots after the break, and be sure to hit the source link if you're interested in grabbing one of these for yourself.

Home Improvement Tips To Make Your Project Successful
Home improvement is something that is very popular among many homeowners. Many homeowners upgrade their home or add on new rooms, while others make cosmetic improvements. Most homes need improvements. To pick up some great ideas for home improvement projects you can handle yourself that give good value for their cost, check out the tips presented below.
Plain lampshades can often be spartan and boring. Brighten up the room by making your own personal designs on your lamp shades and adding a bit of color. You can give life to your home, as it can take away the boring environment you previously had.
See to it that the trees and shrubs near your home are not too close. Since roots can affect your foundation resulting in cracks and leaks, relocate any plants that could cause a potential problem. If there is a tree or shrub too close, transplant it.
Consider a combo unit if you don't have much space available for a separate washing machine and dryer. Various combo washer-dryers can be fitted to replace the space for a dishwasher. A combo unit washes the clothes and when done switches to a dryer.
When it comes to home improvement, get creative and figure out what you are looking to accomplish ahead of time. This allows you to concentrate on the task itself instead of leaving you distracted by details relating to cost and design. There are many places out there to draw inspiration from. Your friends' homes, design TV shows, books and magazines and much more. You can certainly find it if you're looking.
A simple way to add value to your home is to upgrade your appliances. Upgrading to an energy efficient unit can save you money on your electric bill and may even add some value to the home.
It's important that you are having fun in any home improvement job you choose. While you do need to take the work seriously, it should still be fun. In fact, viewing your project as a chore can make you more prone to mistakes. If you do not enjoy this kind of work, it is often best to hire someone else to do the job.
Swap out all light bulbs at your house for the energy efficient kind. This may end up costing you less money in the long run when it comes to your electric bill. Energy efficient light bulbs should be put in place of older models to save money and help the environment.
Don't skimp on the type of paint you buy for the outside of your house. If you select paints that are the best available, you will find that your work lasts a great deal longer. It will also cost you less in the long run and is easier to use. It makes more sense to purchase high quality paint than it does to buy cheap paint and have to repaint within five years.
Take a small organizer and fill it with various fasteners. Keep an assortment of tools and hardware ready for any project that might come up.
Before purchasing or hanging blinds, measure the area thoroughly. Your installation will be easy when you have measured the window exactly and purchased blinds that are the right fit. There are many types of blinds that you could use in your window's interior frame.
If you are looking to improve your home and save some money in the process, consider upgrading your appliances. Inefficient appliances are costly to operate and replacing them will pay for itself quickly. It is also fairly easy to install appliances, so doing so is a home improvement option that is fast and effective.
Be wary of hiring a contractor if there's been a natural disaster. A lot of these contractors lie in wait whenever there is a disaster and will take advantage of desperate homeowners who just want to get their homes repaired as quickly as possible. Do some research before hiring anyone to make repairs to your damaged home.
Take a look at your door knobs. By cleaning or changing the door handles, you can easily change up the look in your home. Look at the handles you have in every room and switch them out with door handles that are brass to ensure a striking change.
Check the professionalism with all of the quotes for your project. Letterheads can be a sign that the business is a professional business, one with a good reputation. Of course, you still need to do other research, but dealing only with companies that use professional letterhead is a good start.
Take the appropriate safety precautions at all times. Although a hardhat might seem like a funny accessory, it can be a life saver if something falls and hits your head in the midst of a repair. Goggles, a breathing apparatus, and a hardhat can keep you safe from harm while you are engaged in a home improvement project.
If you are looking to increase the value of your home with some home improvements, and do not know where to start, consider investing some time with a contractor to give you some ideas. Professionals know exactly what works when trying to improve home value as well give you ideas that you may have never thought of.
Because they can make homes more comfortable to live in and also more valuable to sell, home improvements are, as stated before, a perennial interest to most homeowners. There is always something that could use some fixing in a home. Browse the article above, and choose the best home improvement tips for your home.
