(AP) ? Mixing modest curbs on spending with tax increases reviled by Republicans, President Barack Obama proposed a $3.8 trillion budget on Wednesday that would raise taxes on smokers and wealthy Americans and trim Social Security benefits for millions.

Obama's 2014 blueprint combines a $242 billion infusion of new spending for road and rail projects, early education and jobs initiatives ? all favored by Democrats ? with longer-term savings from programs including Medicare and the military. It promises at least a start in cutting huge annual federal deficits.

The president pitched his plan as a good-faith offer to his GOP rivals since it incorporates a proposal he made to Republicans in December that wasn't radically different from a GOP plan drafted by House Speaker John Boehner. But it follows January's bitterly fought 10-year, $600 billion-plus tax increase that has stiffened GOP resolve against further tax hikes.

"I have already met Republicans more than halfway, so in the coming days and weeks I hope that Republicans will come forward and demonstrate that they're really as serious about the deficit and debt as they claim to be," Obama said.

He was having a dozen Senate Republicans to the White House for dinner Wednesday evening in hopes of building a dialogue on the budget and other topics.

After four years of trillion-dollar-plus deficits in his first term, Obama's plan projects a $973 billion deficit for the current budget year and red ink of $744 billion for the 2014 fiscal year starting in October. By 2016, the deficit is seen as dropping below 3 percent of the size of the economy, a level that many economists say is manageable.

Obama cast his budget as a compromise offer that would bridge differences between Republicans and their desire for reducing government spending and Democrats who want more revenue from taxpayers. But it's difficult to overstate the gulf between Obama and the conservatives who are in the GOP driver's seat in Congress.

While the budget proposal will not prompt any immediate congressional action, it will probably surface this summer when Republicans are expected to demand additional reductions in the deficit in exchange for increasing the nation's borrowing authority.

Obama claims $1.8 trillion in deficit savings over the coming decade, but the budget tables show the savings are actually $1.4 trillion. And $1.2 trillion of that is devoted to reversing automatic, across-the-board spending cuts required because of Washington's inability to follow up a 2011 budget pact with further deficit action.

"This is worse than a status quo budget," said House Budget Committee Chairman Paul Ryan, R-Wis. He said it has about $1 trillion in new taxes, $1 trillion in new spending with deficit reduction of only $119 billion over 10 years under GOP math that sorts through questionable interpretations employed by the White House.

For instance, Obama claims $167 billion in lower war costs ? money the administration never intended to spend ? and uses that "savings" for road projects and other undertakings it bills as jobs initiatives.

The real cuts include $400 billion scrubbed from health care programs like Medicare over the coming decade, including cuts in payments to drug companies and higher Medicare premiums for people who are better off.

The administration would modestly cut the annual operating budgets for both the Pentagon and domestic agencies while reprising ideas like higher Transportation Security Administration fees on airline tickets, the end of Saturday mail delivery and higher pension contributions for federal workers.

"He does deserve some credit for some incremental entitlement reforms," said Boehner, R-Ohio. "But I would hope that he would not hold hostage these modest reforms for his demand for bigger tax hikes. Listen, why don't we do what we can agree to do?"

That's not the way it works, countered Gene Sperling, the director of Obama's National Economic Council. "The offer that is there for Speaker Boehner is not an a la carte menu."

And Rep. Chris Van Hollen, D-Md., said he had reservations about the White House making concessions without getting anything in return. He said, "The president will have to remain firm in his insistence that this is a package deal."

The White House budget claims $580 billion in tax increases on the wealthy over 10 years, including a 28 percent cap on itemized deductions that's never gotten anywhere on Capitol Hill.

The total climbs closer to $1 trillion in tax increases after adding in ideas like a 94 cents-per-pack increase in taxes on cigarettes, changes for corporate foreign earnings, slower inflation adjustments to income tax brackets, elimination of oil and gas production subsidies, an increase in the estate tax, a new "financial crisis responsibility" fee on banks and new taxes on trading of exotic financial instruments known as derivatives.

Republicans predictably slammed Obama's plan for its tax increases, while his Democratic allies generally held their tongues over cuts to Social Security benefits.

"It's not the budget I would write on my own, and it includes several policies that I don't think are the best ways to tackle the deficit and debt," said Senate Budget Committee Chairman Patty Murray, D-Wash.

Reacting more strongly, the senior citizens advocacy group AARP said it was "deeply dismayed that President Obama would propose cutting the benefits of current and future Social Security recipients, including children, widows, veterans and people with disabilities, to reduce the deficit." And AFL-CIO President Richard Trumka, whose organization spent tens of millions of dollars helping re-elect Obama, called the cuts "wrong and indefensible."

The Social Security cuts would come from a slightly stingier inflation adjustment known as "chained CPI" that would reduce annual cost-of-living increases for a variety of programs by about 0.3 percentage points a year. It would reduce federal spending on government programs over 10 years by $130 billion and promises to save far more in subsequent decades.

Once the change was fully phased in, Social Security benefits for a typical middle-income 65-year-old would be about $136 less a year, according to an analysis of Social Security data. At age 75, annual benefits under the new index would be $560 less. But after age 75, Social Security recipients would receive larger-than-scheduled benefit increases by 0.5 percentage points a year through age 85.

Obama promises to ease the burden of the proposal on the poor and the very elderly by not applying it to programs meant for low-income Americans. That means annual increases in assistance programs such as Social Security Supplemental Security Income and Pell Grants for student aid would not be calculated by using the lower inflation formula.

Despite Obama's vows not to raise taxes on the middle class, the chained CPI proposal also would result in higher taxes because tax brackets would be adjusted for inflation more slowly, with much of the effect felt by middle class taxpayers. The provision would raise about $100 billion over 10 years. At the same time, raising the cigarette tax from $1.01 to 1.95 per pack would be disproportionally felt by the poor. That tax increase would raise $78 billion over 10 years.

Obama's plan generally tracks a nonbinding budget measure that passed the Senate last month, though Democrats controlling the chamber left out the chained CPI proposal.

House Republicans, by contrast, muscled through a far more austere plan in March that contains big cuts to Medicaid and would reduce domestic agency budgets by about 20 percent below levels contemplated in a hard-fought 2011 budget pact that set tight "caps" on spending passed by Congress each year.

"I don't think we should be talking about grand bargains because that implies the president and Senate Democrats are ready to embrace fundamental entitlement reform, which they have shown absolutely no indication of doing," said House Budget Chairman Ryan, his party's vice presidential nominee last year.

Such pessimism is also felt by Democrats. Asked this week about the prospects for a broad budget deal, Murray said: "I think we're a long ways from there right now."

Space programs need new approach, Air Force leader says

By Andrea Shalal-Esa

COLORADO SPRINGS, Colorado (Reuters) - The military needs a new approach to developing and buying the satellites that are critical to every military operation, a top Air Force general said on Tuesday, citing growing threats in space and increasing budget pressures closer to earth.

"This time that we're in today absolutely begs for change," General William Shelton, who heads Air Force Space Command, told hundreds of industry executives at the annual National Space Symposium in Colorado Springs, Colorado. "There are storm clouds that are on the horizon."

Shelton said the United States faced a fundamentally altered environment in space, including the threat of a growing amount of space junk and possible hostile acts by enemy nations, coupled with funding problems that could derail key programs.

Military space programs have stabilized after years of massive cost overruns and schedule delays triggered by technical challenges, but tighter budgets and evolving threats are putting a bigger emphasis on affordability for future programs.

Air Force officials are promoting an approach called disaggregation, which would shift the focus to smaller, less complex satellites, at least for some missions, given problems with larger, more complex satellites built in recent years.

They are also studying other options, including buying services from commercial providers and putting government sensors aboard other satellites. Such options are being considered for a new weather satellite.

Northrop Grumman Corp, Boeing Co, Lockheed Martin Corp, and smaller players such as Harris Corp, Moog Inc, ITT Exelis Corp and Orbital Sciences Corp are trying to position themselves to benefit from any change in the Air Force's acquisition approach.

"We see a very steep declining budget," Shelton told reporters after his speech at the conference. "It just speaks very loudly that we need to consider disaggregation."

Mandatory budget cuts that took effect on March 1 have already forced the Air Force to shut down two of six radar receivers that provide data about satellites and debris in space, and cut 100 contractors who worked at the command's headquarters, halving the staff there, officials said.

Shelton told reporters that Air Force Space Command had to cut its fiscal 2013 budget by $508 million under sequestration, and further cuts were likely in coming years.

He declined to give details of the fiscal 2014 budget to be released on Wednesday, but said funding reductions in fiscal year 2015 and beyond would entail some "very tough choices."

For example, Shelton suggested that a new ground-based radar space fence program for which Lockheed Martin Corp and Raytheon Co have been competing might not be funded. The system tracks satellites and space debris.

Shelton said a contract award had been expected in the next month or two, but the program could be vulnerable to cuts in fiscal 2015 and beyond because it was not yet under contract.

He said he favored continuing work on the new space fence, but there were competing priorities within the Air Force budget - including the F-35 fighter built by Lockheed, a new Boeing refueling tanker and development of a new long-range bomber.

"Some serious decisions need to be made in terms of priority," he said. "If you decided you weren't going to continue and award that contract, those investment dollars could be available for investment in other things."

Michael Hamel, a former senior Air Force official and senior vice president at Orbital Sciences, welcomed the Air Force's increasing openness to alternate approaches, but said industry needed tangible evidence sooner than fiscal 2015.

"For a company like ours, two years can be an eternity," Hamel told Reuters at the conference, urging the Air Force to award initial contracts that showed its intent. "There has to be a sense of urgency. Let's take a few steps down this path."

But Rick Ambrose, who heads Lockheed's space division, urged caution, noting that past shifts in Air Force space acquisition had resulted in problems because they curtailed funding for existing programs. Lockheed builds the Air Force's missile warning, secure communications and global positioning satellites, but is also exploring alternative options.

"We're not against disaggregation. We want to make sure we don't quickly rush to a paper-based idea. We want to think it through," Ambrose told Reuters.

Lawmaker invites gun makers to relocate to RI

PROVIDENCE, R.I. (AP) -- A Republican state lawmaker is inviting firearms manufacturers to relocate to Rhode Island from other states he says are "hostile" to gun owners' rights.

House Minority Leader Brian Newberry of North Smithfield made the invitations Monday to Hartford, Conn.-based Colt's Manufacturing Co. and Beretta USA Corp. in Accokeek, Md.

Conservative Republicans across the country also are trying to lure gun makers in case they want to move out of states like Connecticut and Maryland that have passed strict new gun laws.

Newberry says Rhode Island has vacant factories that could support gun manufacturing, and the state would benefit from the jobs.

His invitation came on the eve of Tuesday's planned announcement of nine gun control bills by Rhode Island officials. Newberry says the bills would do nothing to deter criminals.

AACR news: Six2 homeoprotein allows breast cancer cells to detach and metastasize

AACR news: Six2 homeoprotein allows breast cancer cells to detach and metastasize [ Back to EurekAlert! ] Public release date: 9-Apr-2013

'Here we show for the first time that Six2 causes breast cancer progression,' says researcher

In results presented at the AACR Annual Meeting 2013, researchers from the University of Colorado Cancer Center show that the Six2 homeoprotein, while not involved in primary tumor growth, allows cells to detach from substrate and survive their transition through the bloodstream to faraway sites of metastasis.

"Here we show for the first time that Six2 causes breast cancer progression. It's this metastasis, especially to the lung, that can eventually be deadly and so perhaps even more so than affecting the size of the primary tumor, we are especially excited to present this new information about metastasis," says first author Chu-An Wang, PhD, postdoc in the lab of CU Cancer Center investigator Heide Ford, PhD, the paper's senior author.

The Six2 gene codes for a transcription factor that regulates cell growth needed in developing kidney tissues, but then silenced in the healthy, adult body. Some breast cancer cells have discovered a way to reactivate this Six2 gene, which allows them to survive detachment from their tissue of origin and the programmed cell death known as anoikis that makes most wandering cells self-destruct.

Wang and colleagues knocked down Six2 expression in breast cancer cells and showed that the cells' ability to metastasize in mouse models was much reduced. Interestingly, Six2 knockdown did nothing for the cells' ability to grow at the site of origin. Corroborating the claim of Six2's role in metastasis is its correlation with poor prognosis in human breast cancer tissues of 1881 samples examined from the GOBO database, the breast cancer tissues higher in Six2 were simply more aggressively metastatic.

"We're now working to discover Six2's target genes," Wang says. "For example, we hypothesize an effect on the expression of E-Cadherin, whose loss has been implicated in the metastatic potential of many cancers."

Smoking may negatively impact kidney function among adolescents

Apr. 8, 2013 ? Exposure to tobacco smoke could negatively impact adolescent kidney function; this is according to a new study led by a team of researchers at the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins Children's Center. They examined the association between exposure to active smoking and kidney function among U.S. adolescents and found the effects of tobacco smoke on kidney function begin in childhood. The results are featured in the April 2013 issue of Pediatrics.

"Tobacco use and exposure to secondhand tobacco smoke are major health problems for adolescents, resulting in short-term and long-term adverse health effects," said Ana Navas-Acien, MD, PhD, senior author of the study and an associate professor with the Bloomberg School's Department of Environmental Health Sciences. "In this nationally representative sample of U.S. adolescents, exposure to tobacco, including secondhand smoke and active smoking, was associated with lower estimated glomerular filtration rates -- a common measure of how well the kidneys are working. In addition, we found a modest but positive association between serum cotinine concentrations, a biomarker of tobacco exposure, among first-morning albumin to creatinine ratio. These findings further support the conclusion that tobacco smoke may damage the kidneys."

Using a cross-sectional study of 7,516 adolescents ages 12 to 17, the authors assessed participant tobacco use and exposure to secondhand smoke through self-reported data from a home questionnaire and serum cotinine. Participants who reported having smoked "at least one day" in the last month or "at least one cigarette" in the last month, or those who had serum cotinine concentrations over 10 ng/ml were classified as active smokers. Secondhand smoke exposure was defined as non-active smokers who reported living with at least one person who smoked, or who had cotinine levels greater than or equal to 0.05 ng/ml, but less than or equal to 10 ng/ml even if they reported not living with a smoker. Participants with serum cotinine levels below 0.05 ng/ml, not living with a smoker and not smoking in the last month, were classified as unexposed to tobacco.

Earlier studies examining U.S. adolescent tobacco exposure have indicated more than 600,000 middle school students and 3 million high school students smoke cigarettes and 15 percent of non-smoking adolescents report exposure to secondhand smoke at home. Among adolescents, active smoking has been associated with increased asthma risk, reduced lung function and growth, early atherosclerotic lesions and increased cancer risk as well as premature mortality in adulthood. According to Centers for Disease Control and Prevention, smoking is also a risk factor for several autoimmune diseases, including Crohn's disease and rheumatoid arthritis.

"Small changes in the distribution of estimated glomerular filtration rate levels in the population could have a substantial impact in kidney-related illness, as it is well known for changes in blood pressure levels and hypertension-related disease. Evaluating potential secondhand smoke exposure and providing recommendations to minimize exposure should continue to be incorporated as part of children's routine medical care," noted Jeffrey Fadrowski, MD, MHS, co-author of the study and an assistant professor in Pediatric Nephrology at the Johns Hopkins School of Medicine.

"Tobacco as a chronic kidney disease risk factor is of great concern given the high prevalence of use and the chronicity that most often accompanies this exposure. Protecting young people from active smoking is essential since nearly 80 percent of adults who smoke begin smoking by 18 years of age," said Navas-Acien.

Transform an LED Flashlight into an Affordable Ice Light for Beautiful, Evenly Lit Photos

Transform an LED Flashlight into an Affordable Ice Light for Beautiful, Evenly Lit PhotosPart of taking great photos is great lighting, which can be tough to come by if you don't have a lot of money to spend. Thankfully, this light wand produces soft, even lighting thanks to an LED flashlight in the hilt and some clever use of PVC piping. Plus, it does it all without the glaring harshness you would get if you just turned the flashlight on and shone it on your subject.

This tip comes to us from Simon Ellingworth, award winning photographer and author of the photography education blog Lightism (and who's helped us with other photo tips in the past). He used a simple LED flashlight (available at any department store, but he specifically bought this Ultrafire model from Amazon, $12 USD), a 32" length of 1.5" PVC pipe, a PVC end-cap for the pipe, and some zip ties to keep the flashlight in place. From there, he cut out enough of the pipe for the flashlight to rest inside, assembled the whole thing, and turned it on. All of the parts only cost him about ?20 including the cost of the flashlight (about $30 USD), but since the flashlight is a bit cheaper for us, you'll probably come in lower if you make this yourself.

If this looks familiar to his previously mentioned glowstick light, it's because he used the same parts?the LED flashlight provides a brighter, more even light, but he notes you still have to play with the angles to get it looking just right. Hit the link below to see how he made it, and some sample photos he took with the light wand?you'll agree, they look great.

North Korea turns up volume by silencing final military hot line

What happens now?

By Robert Marquand,?Staff writer / March 27, 2013

South Korean Army soldiers patrol along a barbed-wire fence near the border village of Panmunjom in Paju, South Korea, Wednesday. North Korea said Wednesday that it had cut off a key military hot line with South Korea that allows cross-border travel to a jointly run industrial complex in the North.

North Korea's edgy game of war talk continued?at ever higher volumes today with the announcement that it will cut off the last military hot line with South Korea.

Skip to next paragraph Robert Marquand

Staff writer

Over the past three decades, Robert Marquand has reported on a wide variety of subjects for?The Christian Science Monitor, including American education reform,?the wars in the Balkans, the Supreme Court, South Asian politics, and the oft-cited "rise of China." In the past 15 years he has served as the Monitor's bureau chief in Paris, Beijing, and New Delhi.?

?Under the situation where a war may break out any moment, there is no need to keep North-South military communications,? said the regime, according to the Korean Central News Agency in Pyongyang.

The severed line of communication comes as the North, under young and new President Kim Jong-un, has said it is moving into its highest military alert status and has threatened to target Hawaii and Guam with rockets, after last month conducting its third nuclear test.?

The escalating rhetoric has brought a new agreement between US and South Korean officials that would dictate military action should the North cross the border, shell islands, or harm shipping in the kind of low-level actions Pyongyang has attempted in recent years.?

US military officials called the North Korean statement ?bellicose.??Many have expressed doubt that North Korea?s rockets have the range to reach US bases in Guam and Hawaii, but a few, including the?editor of Jane?s Defense Weekly, estimated they could reach US military bases in Japan, according to USA Today.?

Yesterday the small, poor state that is anchored by devotion to the Kim family dynasty, and is now nearly entirely dependent on China for basic sustenance but has also devoted considerable resources to its military, repeated a longstanding threat to turn Seoul into a ?sea of fire,? among other similarly colorful threats.

Earlier this year, the North said it would no longer answer?a hot line at the Demilitarized Zone. The hot line that the country is now threatening to shut down linked the two Koreas at the?Kaesong industrial park, created in the North during the warming winds of unification in the 2000s. The economic complex has long been a symbol of the potential for North-South cooperation.?

The New York Times today notes the North?s threat on the hot line follows comments from?Park Geun-hye,?the newly elected president of South Korea, that North Korea needed to end its nuclear threats in order to gain better traction with the South:

?If North Korea provokes or does things that harm peace, we must make sure that it gets nothing but will pay the price, while if it keeps its promises, the South should do the same,? she said during a briefing from her government?s top diplomats and North Korea policy-makers. ?Without rushing and in the same way we would lay one brick after another, we must develop South-North relations step by step, based on trust, and create sustainable peace.?

Scott Snyder of the Council on Foreign Relations in Washington, a veteran Korea-watcher once based in Seoul, tells The Christian Science Monitor that Pyongyang's main grievance appears to be recent United Nations sanctions targeted at the North.

Mr. Snyder argues that the meaning of the North?s sudden blustery behavior will only become clearer ?once the question of the consolidation of [Kim Jong-un?s] power becomes clearer.?

Agence France-Presse today said that a significant meeting among party elites and power brokers in the closed world of Pyongyang is about to take place.

"They will discuss how to handle the nuclear issue, inter-Korean relations and North Korea's longstanding demand for a peace treaty with the United States," Professor Yang Moo-jin of the University of North Korean Studies in Seoul told AFP.

Comparisons between the new Kim and his grandfather, Kim Il-sung, the patriarch of North Korea, are flowing freely, since there is a resemblance between the two. But Snyder notes that too little is yet known of the young Kim, who took over from his father Kim Jong-il last year, and that his youth is not necessarily a plus in such a high-stakes game.

?Right now the song is the same, but the volume is a lot louder. We don?t know his risk tolerance yet ? does he understand the game he is playing??

The US-South Korea military agreement follows a recent scrapping by the North of the historic legal armistice that effectively ended the Korean war in the 1950s. It came on the anniversary of the infamous sinking of the Choenan Navy vessel in 2010, which resulted in the deaths of 46 South Korean sailors, something that has had powerful emotional resonance in the South. (The Choenan was raised from the ocean floor, and forensics by the South claim the vessel was torpedoed by the North, something the North denies.)?

USA Today quotes an Asia-watcher who feels the key to dealing with Pyongyang runs through Beijing:

US diplomats should talk to their Chinese counterparts and say, "Your ally North Korea is acting in a very belligerent and destabilizing way," said [Richard] Bush, who heads the Brookings Institution Center for Northeast Asian Policy Studies. "They're acting in ways that are contrary to the principles you [China] have laid out. The situation is somewhat dangerous. You need to restrain your ally."

(AP) ? More than a few people have suggested to the producers of the Academy of Country Music Awards that they extend the broadcast delay for Sunday night's show ? just in case.

With Blake Shelton and Luke Bryan co-hosting, everyone expects the unexpected ? and several off-color, unscripted moments ? as country music's biggest cut-ups collide on stage. A recent interview in Nashville with the two, who've given themselves the celebrity couple name "Bluke," veered wildly from a discussion of Bryan's unworthiness to host to crude jokes and Taylor Swift's fans.

"I would tell him to be prepared for the onslaught of hatred that will come from Taylor Swift's fan base if you say any sort of a joke or if she's any part of a punch line in the monologue," Shelton said when asked what advice he'd give Bryan. "By the way, you're getting all those jokes this year."

The 48th annual awards show kicks off at 8 p.m. EDT Sunday night live on CBS from the MGM Grand in Las Vegas. The night will be a showcase for country's men of the moment ? and for its two dominant male stars of the last two decades.

Many of the top names in country music will perform or appear, including top nominees Eric Church and Hunter Hayes, but most eyes will be on the marquee meeting of Garth Brooks and George Strait. Brooks and Strait, two of music's top-selling artists regardless of genre, have never performed together.

They will help honor the show's longtime producer Dick Clark, who passed away last year. The academy is naming its artist of the decade award for Clark, whose tenure with the show began in 1979.

The moment will be special ? and not just for the millions watching at home. It has country's biggest stars abuzz as well.

"Having George and Garth on stage together at one time on an awards show will become one of the most important pieces of tape in country music history," Dierks Bentley said.

Church leads all nominees with seven, while Hayes is up for six awards. Shelton, Bryan and Jason Aldean ? country's top three male stars of the moment ? are up for the fan-voted entertainer of the year award ? though they're facing off against academy favorite Miranda Lambert, who is Shelton's wife, and two-time winner Taylor Swift, a heavy favorite to three-peat given her relationship with fans.

Shelton is arguably country's most visible male today. "The Voice" coach has a weekly presence on national television, was the recent winner of the rival Country Music Association's entertainer of the year award and has risen to platinum status again after a mid-career lull that's a distant memory.

Aldean is country's best-selling male artist at the moment and Church and Bryan have recently joined him as acts who can fill arenas and reach multiplatinum sales.

They're so prevalent at this year's awards, they've elbowed out traditional nominees like Brad Paisley, who was shut out of the nominations for the first time since 1999, and Kenny Chesney, a perennial entertainer of the year nominee who was left out of the category despite putting on 2012's most talked about event ? his stadium tour with Tim McGraw.

Shelton will kick off the show with a performance of his new single "Boys 'Round Here" that will include appearances by Bryan, Brad Paisley, who's also hosting the academy's concurrent Fan Jam a mile down the road at The Orleans, Sheryl Crow and Lambert's trio the Pistol Annies.

Hayes will be joined by another performer who got his start as a precocious teen ? Stevie Wonder, making his first appearance on the show.

Aldean, Chesney, McGraw, Bentley, Carrie Underwood and Kelly Clarkson also are scheduled to perform.

Church was nominated for the second consecutive year for album of the year for his breakthrough "Chief." He's up against Swift's "Red," Underwood's "Blown Away," Bryan's "Tailgates & Tanlines" and Little Big Town's "Tornado." Producer Jay Joyce has two nominations in the category with Church and Little Big Town.

Shelton and Lambert will defend their male and female vocalist of the year wins. Shelton faces Church, Bryan, Aldean and Toby Keith, while Lambert competes with Underwood, Swift, Martina McBride and newcomer Kacey Musgraves.

Make Something Unreal Live 2013: The final four | bit-gamer.net

Just how difficult is it to develop a computer game? Well, just ask the four teams competing in Epic Games' Make Something Unreal Live competition currently drawing to a close at the Gadget Show Live at the NEC in Birmingham.

The competition tasks teams of university students to develop a full 3D game demo in just five months using the freely available Unreal Development Kit. The prize? The opportunity to bag themselves a full Unreal Engine 4 development license.

This year the guiding theme was of ?Mendelian inheritance: genetics and genomics?. This broad yet subtly complex theme is quite a challenging one to convey in the mechanics of a computer game but the teams have had a little help. Advice on the science side has come from the Sanger Institute while on the gaming side Climax Studios, Lucid Games, Ninja Theory and Splash Damage have all lent a hand.

Kicking off in October last year, the dozens of entrants have been whittled down to just four who are spending this week putting the final touches to their games, not from the comfort of their homes or university dorms but under the watchful gaze of thousands of members of the public who are visiting the Gadget Show Live.

The winners of the competition will be announced at the end of the show on Sunday evening but earlier in the week we got the chance to play on all the games to see just what a bunch of no good layabout students can achieve in five months, and the answer is rather a lot...

Beings

University: University of Abertay, Dundee
Team/Company Name: Team Summit
Team Members: Gaurav Pant - Programmer and PR Manager, Vijay Kesiraju - Lead Programmer, Claudio Bozzotta - Designer, Clement Marcou - Producer and Artist

Beings is in some ways the most surprising game of the bunch because it is targeted at a very young audience. Aimed at players of 3 years+, it combines rainbow coloured, twee visuals, soporific gentle music and easy to pick up platforming gameplay to create a surprisingly effective my-first-genetics-lesson feel.

Make Something Unreal Live 2013: The final four Make Something Unreal Live: The final four

The player is tasked with controlling a floppy-eared rabbit-like creature with - bizarrely enough - a jelly on its back. To progress through the game this creature has to upgrade itself by breeding with the female bunny creature and taking on its genetic powers - fire resistance, higher jumping ability, etc. But, to become sufficiently attractive to the female you must first collect all the stars scattered around the level.

It's an intriguing concept, though we're a little unsure of the flirty precursor to the two creatures mating - maybe it would go straight over the head of a three year old but to us it seemed a little too suggestive.


This was the most polished of the games at the time we played them with genuinely enchanting visuals and sound as well as having the most clear in-game instructions on how to play. But, to us the gameplay did seem siultanesously to be a little to easy for older players and perhaps too complicated for smaller children - certainly the genetics mechanic would go over the heads of most children under 5, we would have thought. Plus, the demo was extremely short. It is longer than shown in our video, but not by much. Still we like that the team has tried something different and are looking forward to seeing what can be achieved by the time the competition ends.

What has the biggest challenge been?
The biggest challenge that we faced in this competition is that we are just four people against a whole lot. Being the smallest team, competing against teams that already have sponsors and proper work spaces, its like a David-Goliath scenario going on here. This means that we have to work three times more than the others to prove our worth, and I am glad that we have made our mark and have done so.

What you would use the Unreal Engine 4 license for?
Well, when we receive the licence, we shall work further on our project and bring out as a completed title. Once this is achieved, we would like to take up a new project that could show off and utilize the true potential that the Unreal Engine 4 has to offer.

What advice you would give others who are looking to make a start in games development?
Well if it comes to advice, I would just like to say that have a clear idea about what you intend to do and stick to it till the end with all your passion. Keep an open minded and listen to other's suggestions but do not get intimidated and completely change your gameplay. Be optimistic and hopeful. Try to find out your weaknesses as you can yourself be your best critic. As people say that problem identified is problem half solved.

Epigenisis

University: Blekinge Institute of Technology
Team/Company Name: Dead Shark Triplepunch
Team Members: Michael Levall - Project and Creative lead, Tobias Johansson - Level Design / PR, Jonas Vigstrand - UI Designer, Martin Bergman - 3D Artist, Carl Bostr?m - 3D Artist, Henrik Giang - Lead Artist, Andr? J?nsson - VFX and 3D Artist, Jonathan Wising - Lead Programmer, Joakim Westblad - Balance Designer and Programmer, Ola B?ckstr?m - Audio Lead

Easily the most instantly playable and fun of the games on showm, at least for experienced gamers, was Epigenisis. It's a sports game that feels like a cross between basketball and Unreal Tournament capture the flag. Teams must capture the ball placed in the centre of the map and throw it through the other team's goal on the opposite side of the map.

Make Something Unreal Live 2013: The final four Make Something Unreal Live: The final four

Players can shoot at each other with weapons that, rather than injuring each other, knock the other players aside. With the map being made up of a series of small squares suspended in space, a blast or two will generally result in a fall to oblivion - a five second wait and you respawn to start again.


The genetics bit comes into play when a team has scored a goal. The prize for each goal is a seed which the team can then plant on one of the squares. These grow into various plants that help the team out, such as a tree type plant that shields the team or a smoke emitting plant that produces a one-way smoke screen.

It's a pretty tenuous link to the brief but the game is instantly good fun and we can genuinely see a broad audience getting involved upon a full release.

What has the biggest challenge been?
The biggest challenge has been getting people to understand everything in the game. We have been play-testing the game since day one to make sure people understand it. We are definitely getting towards that goal. People here at Gadget Show Live that plays the game picks the concept up within just a few minutes which is great, and that is as I said something we have worked extremely hard with. So we feel really happy when we see people playing it and having fun with it.

What you would use the Unreal Engine 4 license for?
The first thing we would think about is if we should port Epigenesis to the new engine. That however would delay the game so it's a fine line if we should do that or not. But other than that we don't really dare to talk about what we would do with it. All the teams here have a great change of winning so it feels a little bit scary to discuss what we would do if we win. However as I said we have some ideas in store if we get the license.

What advice you would give others who are looking to make a start in games development?
Start small. Don't think your first game is going to be Minecraft or Super Meat Boy, those games both took several years to make and if someone just starting with game development sets out on a task like that it's most likely you never finish the first game.

So start really small and with something easy. There are excellent engines to get people started in games. Game Maker is a good thing to start out with, it's easy to grasp and easy to get started. And start by doing a small clone of something like the first Super Mario Bros. in it, but begin with only walking and jumping. The rest of the things you should add as you learn more.

Later when you feel more confident and have learned some game development, begin looking into UDK and other 3D Engines. It's a harder task of getting into a 3D engine so don't feel discouraged when starting, there are a lot of free tutorials that you could use. But still keep the games small and make sure you finish the games rather than thinking about doing something too big. For us on Dead Shark we would also recommend reading Game Design - The book of lenses by Jesse Schell.

Charlotte Mayor Foxx will not seek re-election

CHARLOTTE, N.C. ?

Mayor Anthony Foxx, considered a rising star in the Democratic Party, said Friday he would not run for re-election, but he didn't indicate what he planned to do next.

Foxx was the public face of Charlotte during the Democratic National Convention last summer. He worked for more than a year helping promote the three-day event, which attracted 35,000 delegates, journalists and others to the state's largest city.

Foxx, 41, became this city's youngest and its second African-American mayor when he was elected in 2009 to his first two-year term after serving on the city council.

He will leave office in January. The father of two said he wasn't running again in part to spend more time with his family.

"My children, who were both born during my service, are getting older - and they still like hanging around with me. I do not want to be a father who looks back and wishes I had spent more time with them," Foxx said in a statement.

Michael Bitzer, a Catawba College political science professor, said Foxx will have numerous opportunities if he wants to continue his future in politics.

"He's relatively young and ... based on his comments so far, he wants to be with his children and be a normal father. But I can't help but think others have eyes on him for certainly higher office - if not a cabinet position," he said.

His spokeswoman said Foxx would be unavailable to talk about his decision on Friday. In his statement, he focused on his accomplishments.

Foxx said he was leaving Charlotte in better shape than it was in 2009. At the time, the city, a major financial center, had lost thousands of jobs because of the recession. During two-terms, Foxx pushed for expansion of light rail service and the creation of a streetcar line.

Foxx replaced Pat McCrory, a Republican, who was elected last year as governor of North Carolina.

Accidental discovery may lead to improved polymers

TORONTO, ON Chemical Engineering Professor Tim Bender and Post-Doctoral Fellow Benoit Lessard's discovery of an unexpected side product of polymer synthesis could have implications for the manufacture of commercial polymers used in sealants, adhesives, toys and even medical implants, the researchers say.

Bender and Lessard discuss their discovery in "Boron subphthalocyanine polymers by facile coupling to poly (acrylic acid-ran-styrene) copolymers and the associated problems with autoinitition when employing nitroxide mediated polymerization," a paper published this month in Macromolecular Rapid Communications and online at MaterialsView.com.

"People in polymer synthesis would be very interested in the process described in our paper, as we document the discovery of a side-product. This side-product is quite unexpected based on our current knowledge of polymer chemistry," Bender said.

Bender and Lessard describe a synthesis of Boron subphthalocyanines (BsubPcs) containing polymers that can be used in organic electronic devices. What makes the article significant is that it also describes their discovery of a new side product of a common polymer synthesis technique, which would not have been observed without the addition of the BsubPc to this standard polymer.

"Currently BsubPc polymers do not have any commercial applications. However, by studying their properties and finding new and inexpensive ways to synthesize them, we are able to open the door for potential applications in the field of organic electronics," Lessard said.

Commercial polymers may also contain this particular side product, Bender and Lessard wrote. If the side product can be reduced or eliminated, more of the polymer could be produced with more consistent quality.

Bender and Lessard are also investigating the optical and electrical properties of BsubPc polymers for possible use in organic electronic devices, such as organic field-effect transistors, organic light emitting diodes and organic photovoltaics. Applying polymers in organic electronics may lead to more flexibility, lighter weight and lower manufacturing costs, they wrote.
