Obama's State of the Union: Jobs, re-election time (AP)

WASHINGTON ? Vilified by the Republicans who want his job, President Barack Obama will stand before the nation Tuesday night determined to frame the election-year debate on his terms, using his State of the Union address to outline a lasting economic recovery that will "work for everyone, not just a wealthy few."

As his most powerful chance to make a case for a second term, the prime-time speech carries enormous political stakes for the Democratic incumbent who presides over a country divided about his performance and pessimistic about the nation's direction. He will try to offer a stark contrast with his opponents by offering a vision of fairness and opportunity for everyone.

In a preview Saturday, Obama said in a video to supporters that the speech will be an economic blueprint built around manufacturing, energy, education and American values.

He is expected to announce ideas to make college more affordable and to address the housing crisis still hampering the economy three years into his term, people familiar with the speech said. Obama will also propose fresh ideas to ensure that the wealthy pay more in taxes, reiterating what he considers a matter of basic fairness, the officials said.

His policy proposals will be less important than what Obama hopes they all add up to: a narrative of renewed American security with him at the center, leading the fight.

"We can go in two directions," Obama said in the campaign video. "One is toward less opportunity and less fairness. Or we can fight for where I think we need to go: building an economy that works for everyone, not just a wealthy few."

That line of argument is intended to tap directly into concerns of voters who think America has become a nation of income inequality, with rules rigged to help the rich. The degree to which Obama or his eventual Republican opponent can better connect with millions of hurting Americans is expected to determine November's presidential election.

Obama released his video hours ahead of the South Carolina primary, where Republican candidates fought in the latest fierce contest to become his general election rival.

The White House knows Obama is about to get his own stage to outline a re-election vision, but carefully. The speech is supposed to an American moment, not a campaign event.

Obama didn't mention national security or foreign policy in his preview, and he is not expected to break ground on either one in his speech.

He will focus on the economy and is expected to promote unfinished parts of his jobs plan, including the extension of a payroll tax cut that is soon to expire.

Whatever Obama proposes is likely to face long odds in a deeply divided Congress.

More people than not disapprove of Obama's handling of the economy, and he is showing real vulnerability among the independent voters who could swing the election. Yet he will step into the moment just as the economy is showing life. The unemployment rate is still at a troubling 8.5 percent, but at its lowest rate in nearly three years. Consumer confidence is up.

By giving a sneak peek to millions of supporters on his email list, Obama played to his Democratic base and sought to generate an even larger audience for Tuesday's address. He is unlikely to getter a bigger stage all year.

More people watched last year's State of the Union than tuned in to see Obama accept the Democratic presidential nomination in Denver in 2008.

The foundation of Obama's speech is the one he gave in Kansas last month, when he declared that the middle class was at a make-or-break moment and he railed against "you're on your own" economics of the Republican Party. His theme then was about a government that ensures people get a fair shot to succeed.

The State of the Union will be the details to back that up.

But even so, the speech will still be a framework ? part governing, part inspiration.

The details will be rolled out in full over the next several weeks, as part of Obama's next budget proposal and during his travels, which will allow him more media coverage.

On national security, Obama will ask the nation to reflect with him on a momentous year of change, including the end of the war in Iraq, the killing of al-Qaida terrorist leader Osama bin Laden and the Arab Spring protests, with people clamoring for freedom. He is expected to note the troubles posed by Iran and Syria without offering new positions about them.

Despite low expectations for legislation this year, Obama will offer short-term ideas that would require action from Congress. For now, the main looming to-do item is an extension of a payroll tax cut and unemployment benefits, both due to expire by March.

His travel schedule following his speech, to politically important regions, offers clues to the policies he was expected to unveil.

Both Phoenix and Las Vegas have been hard hit by foreclosures. Denver is where Obama outlined ways of helping college students deal with school loan debt. Cedar Rapids, Iowa, and Detroit are home to a number of manufacturers. And Michigan was a major beneficiary of the president's decision to intervene to rescue the American auto industry.

Republican leaders in Congress say Obama has made the chances of cooperation even dimmer just over the last several days. He enraged Republicans by installing a consumer watchdog chief by going around the Senate, which had blocked him, and then rejected a major oil pipeline project the GOP has embraced.

Obama is likely, once again, to offer ways in which a broken Washington must work together. Yet that theme seems but a dream given the gridlock he has been unable to change.

The address remains an old-fashioned moment of national attention; 43 million people watched it on TV last year. The White House website will offer a live stream of the speech, promising extra wrinkles for people who watch it there, and then invite people to send in questions to administration officials through social media such as Twitter and Facebook.

Obama's campaign is also organizing and promoting parties around the nation for people to watch the speech.

Paul says his campaign's momentum will continue (AP)

COLUMBIA, S.C. ? Republican presidential candidate Ron Paul told supporters Saturday that the momentum of his campaign will continue.

Paul told a cheering crowd that his campaign started as a way to grow support for his libertarian ideas. But now he said his campaign is focused on winning delegates to secure the GOP nomination for the White House.

Exit polls showed the Texas congressman placing fourth in the state's Republican primary Saturday evening.

Study Hints That Statins Might Fight Breast Cancer (HealthDay)

THURSDAY, Jan. 19 (HealthDay News) -- Amid hints that statins -- cholesterol-lowering drugs -- might also play a role in preventing or treating certain types of cancer, new research sheds some light on how these drugs may help stop breast cancer in its tracks among certain women.

The p53 tumor suppressor gene stops the uncontrolled growth of cancer cells, but some women with breast cancer have mutant forms of this gene. In the new study, when the mutant p53 cells were treated in the laboratory with statins, the cells stopped their erratic growth, and even died in some cases.

It seems that the mutated p53 genes may activate the same pathway that the statins inhibit -- the mevalonate pathway, the study suggests. The mevalonate pathway is important in the body's production of cholesterol.

In the study, the effects of the statin drugs were erased when the mevalonate pathway was reactivated, supporting the potential mechanism. The new research is published in the Jan. 20 issue of the journal Cell.

Study author Dr. Carol Prives, chair of the department of biological sciences at Columbia University in New York City, is cautious in her enthusiasm about the results and their implications.

"The study is adding the possibility that there may be classes of breast cancer patients who will respond better to statins than others," she said, but noted that this research is far away from the bedside.

"By understanding better what sort of cells would respond to statins, one might have a better idea of whether or not to consider using them," she added. "The next step could be a trial of statins in women with breast cancer who have a mutated copy of the p53 gene."

Commenting on the study, cancer expert Marc Symons said, "This paper unravels a mechanism whereby p53, a frequently mutated cancer gene, promotes the aberrant behavior of cancer cells."

The mutated protein stimulates the mevalonate pathway, explained Symons, an investigator at the Center for Oncology and Cell Biology at the Feinstein Institute for Medical Research in Manhasset, N.Y.

"Statins, drugs that are widely used to lower cholesterol levels, block a key step in the mevalonate pathway," Symons said. "The new results may well give new momentum to the use of statins as anti-cancer agents."

Dr. Stephanie Bernik, chief of surgical oncology at Lenox Hill Hospital in New York City, is also intrigued by the potential of the new findings.

"This paper addresses a possible new target for therapeutic agents based on a well-known tumor suppressor gene that is common in many cancers," Bernik said. "Identifying novel pathways that lead to tumor formation is the first step to developing new drugs that can specifically target some of the complex mechanisms that contribute to the development of cancer," she pointed out.

"This work and other projects like this raise the hope that we will one day be able to cure cancers on a molecular level," Bernik said.

WASHINGTON (AP) ? Caving to a massive campaign by Internet services and their millions of users, Congress indefinitely postponed legislation Friday to stop online piracy of movies and music costing U.S. companies billions of dollars every year. Critics said the bills would result in censorship and stifle Internet innovation.

The demise, at least for the time being, of the anti-piracy bills was a clear victory for Silicon Valley over Hollywood, which has campaigned for a tougher response to online piracy. The legislation also would cover the counterfeiting of drugs and car parts.

Congress' qualms underscored how Internet users can use their collective might to block those who want to change the system.

The battle over the future of the Internet also played out on a different front Thursday when a loose affiliation of hackers known as "Anonymous" shut down Justice Department websites for several hours and hacked the site of the Motion Picture Association of America after federal officials issued an indictment against Megaupload.com, one of the world's biggest file-sharing sites.

The site of the Hong Kong-based company was shut down, and the founder and three employees were arrested in New Zealand on U.S. accusations that they facilitated millions of illegal downloads of films, music and other content, costing copyright holders at least $500 million in lost revenue. New Zealand police raided homes and businesses linked to the founder, Kim Dotcom, on Friday and seized guns, millions of dollars and nearly $5 million in luxury cars, officials there said.

In the U.S., momentum against the Senate's Protect Intellectual Property Act and the House's Stop Online Piracy Act, known popularly as PIPA and SOPA, grew quickly on Wednesday when the online encyclopedia Wikipedia and other Web giants staged a one-day blackout and Google organized a petition drive that attracted more than 7 million participants.

That day alone, at least six senators who had co-sponsored the Senate legislation reversed their positions. House Speaker John Boehner, R-Ohio, in statements at the time and again on Friday, stressed that more consensus-building was needed before the legislation would be ready for a vote.

On Friday, Senate Majority Leader Harry Reid, D-Nev., said he was postponing a test vote set for Tuesday "in light of recent events." House Judiciary Committee Chairman Lamar Smith, R-Texas, followed suit, saying consideration of a similar House bill would be postponed "until there is wider agreement on a solution."

With opposition mounting, it was unlikely that Reid would have received the 60 votes needed to advance the legislation to the Senate floor.

The two bills would allow the Justice Department, and copyright holders, to seek court orders against foreign websites accused of copyright infringement. The legislation would bar online advertising networks and payment facilitators such as credit card companies from doing business with an alleged violator. They also would forbid search engines from linking to such sites.

The chief Senate sponsor, Judiciary Committee Chairman Patrick Leahy, D-Vt., cited estimates that copyright piracy costs the American economy more than $50 billion annually and that global sales of counterfeit goods via the Internet reached $135 billion in 2010. He and Smith insist that their bills target only foreign criminals and that there is nothing in them to require websites, Internet service providers, search engines or others to monitor their networks.

That didn't satisfy critics who said the legislation could force Internet companies to pre-screen user comments or videos, burden new and smaller websites with huge litigation costs and impede new investments.

The White House, while not taking a specific stand on the bills, last week said it would "not support any legislation that reduces freedom of expression ... or undermines the dynamic, innovative global Internet." On Friday, White House spokesman Jay Carney said online piracy is an issue that has to be addressed, "but everybody has to be in on it for it to work and get through Congress."

The scuttling, for now, of PIPA and SOPA frustrates what might have been one of the few opportunities to move significant legislation in an election year where the two parties have little motivation to cooperate.

Until recently "you would have thought this bill was teed up," with backing from key Senate leaders and support from powerful interest groups, said Sen. Jerry Moran, R-Kan., who cosponsored the original bill but quickly dropped his backing on the grounds the bill could undermine innovation and Internet freedom.

Moran said the "uprising" of so many people with similar concerns was a "major turnaround, and in my experience it is something that has happened very rarely."

Moran said PIPA and SOPA now have "such a black eye" that it will be difficult to amend them. Reid, however, said that there had been progress in recent talks among the various stakeholders and "there is no reason that the legitimate issues raised by many about this bill cannot be resolved."

Jeff Chester, executive director for the Center for Digital Democracy, a consumer protection and privacy advocacy group, said Google and Facebook and their supporters "have delivered a powerful blow to the Hollywood lobby." He predicted a compromise that doesn't include what many see as overreaching provisions in the current legislation.

"It's been framed as an Internet freedom issue, but at the end of the day it will be decided on the narrow interests of the old and new media companies," he said. The big questions involve who should or shouldn't pay ? or be paid ? for Internet content.

Leahy said he respected Reid's decision to postpone the vote but lamented the Senate's unwillingness to debate his bill.

"The day will come when the senators who forced this move will look back and realize they made a knee-jerk reaction to a monumental problem," Leahy said. Criminals in China, Russia and other countries "who do nothing but peddle in counterfeit products and stolen American content are smugly watching how the United States Senate decided" it was not worth taking up the bill, he said.

In the House, Smith said he had "heard from the critics" and resolved that it was "clear that we need to revisit the approach on how best to address the problem of foreign thieves that steal and sell American inventions and products." Smith had planned on holding further committee votes on his bill next month.

The bill's opponents were relieved it was put on hold.

Markham Erickson, executive director of NetCoalition, commended Congress for "recognizing the serious collateral damage this bill could inflict on the Internet."

The group represents Internet and technology companies including Google, Yahoo and Amazon.com. Erickson said they would work with Congress "to address the problem of piracy without compromising innovation and free expression."

Rep. Darrell Issa, R-Calif., who has joined Sens. Ron Wyden, D-Ore., and Moran in proposing an alternative anti-piracy bill, credited opponents with forcing lawmakers "to back away from an effort to ram through controversial legislation."

But the CEO of the Motion Picture Association of America, former Connecticut Democratic Sen. Chris Dodd, warned, "As a consequence of failing to act, there will continue to be a safe haven for foreign thieves." The MPAA, which represents such companies as Walt Disney Studios Motion Pictures, Twentieth Century Fox Film Corporation and Warner Bros. Entertainment Inc., is a leading advocate for the anti-piracy legislation.

The power of flowers: Research sprouts a closer look at sunflower genetics

MANHATTAN, KAN. -- A Kansas State University researcher's plant genetic work is rooted in the sunflower state.

Mark Ungerer, associate professor of biology, has two major research projects that involve evolutionary change in sunflowers, the state flower of Kansas.

"What we do in the lab is referred to as ecological or evolutionary genetics," Ungerer said. "We study naturally occurring species and try to understand the genetic basis or genetic underpinnings of natural variation."

There are more than 50 species of sunflowers. Some are annual plants -- meaning they germinate, flower and die in one year -- and some are perennial plants that grow and bloom every year and live longer.

Ungerer's first project focuses on five species of annual sunflowers: two parent species and three hybrid derivative species. All three hybrid species arose from ancient hybridization events between the same two parents -- an unusual way for new species to develop, Ungerer said.

"What also makes the system unique is that the hybrid species are recently derived in the last half a million years," Ungerer said. "It seems like a long time, but that is actually pretty recent in evolutionary terms."

But there is another interesting aspect of the three hybrid species: While they have the same number of chromosomes as the two parent species, the hybrid species' genomes are 50 to 75 percent larger in terms of the amount of DNA.

Ungerer's research team made an important discovery that explains this DNA difference. The researchers studied long terminal repeat, or LTR, retrotransposons, which are mobile genetic elements that can copy themselves and insert the copies into various chromosome locations. Ungerer's team discovered that the hybrid species and the parent species were different because of massive proliferation events, or rapid reproduction, of the LTR retrotransposons. Not only that, these transposable elements are still active and cause mutations in sunflowers.

"It's like a smoking gun," Ungerer said. "It helps us study the process."

The researchers now want to know the triggers of these proliferation events and how the species have reacted to this increase in genome size. Ungerer has received $610,000 from the National Science Foundation to study these rapid proliferation events and how they affect the evolution of the hybrid sunflowers.

"Although virtually all plants and animals have these types of sequences in their genomes, we still know very little about what phenomena cause them to amplify and make extra copies of themselves," Ungerer said.

Ungerer is studying two naturally occurring phenomena -- hybridization and stress -- that are hypothesized to cause proliferation of these mobile DNA sequences. The group of five annual sunflowers provides an excellent system to study the roles of hybridization and stress because not only have the three hybrid species arisen from ancient hybridization events, but they also are locally adapted to harsh and stressful environments, unlike their parental species. Two of the hybrid species grow in the desert and the third hybrid species grows in salt marshes, Ungerer said.

Ungerer's second project looks at clinal variation of a perennial sunflower species. This species has a wide geographic distribution across central North America and grows in areas from Texas north to Manitoba, Canada. Ungerer wants to understand population differences between sunflowers in different parts of the region.

For this research, Ungerer's team is conducting common garden experiments, which involve gathering seeds from each of the populations across central North America. The Kansas seeds came from the Konza Prairie Biological Station. The seeds are then grown in the same common garden at Kansas State University.

"If you see differences among plants in a common garden experiment, you attribute that to genetic differences of populations at these different locations," Ungerer said. "We have found striking differences."

Some of these striking differences include germination and flowering time. For example, because the growing season in Manitoba is much shorter, sunflowers grow quickly and flower in about two months. In Texas, where the growing season is much longer, sunflowers grow much slower and the plants grow much larger before they flower in about seven months.

"Now we are trying to expand this research to look at some of the underlying genetics of these differences," Ungerer said.

His second project has been funded by the K-State Integrated Genomic Facility and the Division of Biology's Research Experiences for Undergraduates program.

###

In addition to his sunflower work, Ungerer has several ongoing research projects. He is studying freezing tolerance of Arabidopsis thaliana, a model plant species, across several geographic regions. He is also working with other K-State biology researchers to study mating patterns of the bison herd on the Konza Prairie.

A look at key moments from the SC GOP debate (AP)

NORTH CHARLESTON, S.C. ? Some notable moments from Thursday's debate, the last such forum before the South Carolina Republican presidential primary:

___

Newt Gingrich and `open marriage' question:

The first question of the evening cited the allegation by Gingrich's second wife, Marianne, that he had sought an open marriage. That triggered any angry response from the former speaker of the House.

"I think the destructive, vicious, negative nature of much of the news media makes it harder to govern this country, harder to attract decent people to run for public office. And I am appalled that you would begin a presidential debate on a topic like that," he scolded the host, CNN's John King.

"Every person in here knows personal pain. Every person in here has had someone close to them go through painful things," Gingrich continued. "To take an ex-wife and make it two days before the primary a significant question for a presidential campaign is as close to despicable as anything I can imagine."

After attacking the media one more time, Gingrich got down to his response to the story itself ? and blamed the media again.

"The story is false. Every personal friend I have who knew us in that period said the story was false. We offered several of them to ABC to prove it was false. They weren't interested because they would like to attack any Republican," he finished. "I am tired of the elite media protecting Barack Obama by attacking Republicans."

___

Releasing tax returns:

Gingrich released his income tax returns during the debate. Former Massachusetts Gov. Mitt Romney said he'll release his around April, and added that he'd be "happy" to release more than one year. Former Sen. Rick Santorum said he does his own, they are on his home computer and when he gets back and finishes them, he'll release them. Texas Rep. Ron Paul said he never considered releasing his in part because, as a congressman, he's required to disclose his information yearly.

Romney's taxes have drawn the most attention. "I want to make sure that I beat President Obama. And every time we release things drip by drip, the Democrats go out with another array of attacks. As has been done in the past, if I'm the nominee, I'll put these out at one time so we have one discussion of all of this," said Romney, who is worth as much as $250 million. "I obviously pay all full taxes. I'm honest in my dealings with people. People understand that. My taxes are carefully managed and I pay a lot of taxes. I've been very successful and when I have our ? our taxes ready for this year, I'll release them."

___

Santorum on overturning the health care law:

He pointed out that Romney was governor when Massachusetts passed a health care overhaul on which Obama's is based, and that Gingrich supports mandated health insurance. In contrast, Santorum said, he authored health care savings accounts as far back as 1991.

"These are two folks who don't present the clear contrast (with Obama) that I do," Santorum said. "I've been fighting for health reform, private sector, bottom up, the way America works best, for 20 years, while these two guys were playing footsie with the left."

___

Santorum questions Gingrich's dependability:

Gingrich, Santorum suggested, is running his campaign with something other than "cogent thoughts."

If Gingrich becomes the Republican presidential candidate, Santorum said, "you sort of have that worrisome moment that something's going to pop. And we can't afford that in a nominee."

Catholics in Poland parade a ?holy finger?

?It?s a finger from his right hand from which he often gave a blessing to St. Faustina.?

Roman Catholics in Poland is ready to take a "holy finger" out for a stroll.

The Most Rev. Edward Ozorowski, Archbishop of Bialystok, Poland, brought a relic of Blessed Michael Sopocko, who was St. Faustina?s confessor and spiritual director.

The principal celebrant at the Solemn Liturgy on Divine Mercy Sunday came bearing a special gift for the Marians of the Immaculate Conception of the Blessed Virgin Mary.

?It?s a finger from his right hand from which he often gave a blessing to St. Faustina,? explained Br. Andrew R. Maczynski, MIC, general promoter of the Association of Marian Helpers.

The relic, which came encased in a golden monstrance, is about 5 centimeters long. It will be placed in the National Shrine, which is administered by the Marians.

Bishop Ozorowski, in whose archdiocese Blessed Michael Sopocko was beatified Sept. 28, 2008, presented the gift during Holy Mass on Sunday.

?We express our sincere gratitude to His Excellency for making it possible that a relic of St. Faustina?s spiritual director will find its place here in the National Shrine of The Divine Mercy,? said Br. Chris Alar, MIC, during the presentation.

This is another detail worth mentioning. It is recorded by another Catholic news site

?The relic will join another relic in the Shrine ? the ?basal phalanx? of a great toe of St. Faustina, to be exact. A larger piece of her relic remains in a reliquary within the Shrine.

My comment:

The skull and bone files on News That Matters will now include some hot stuff from Poland.

?Matthew 23:27
?Woe to you, teachers of the law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of the bones of the dead and everything unclean.

You have to be completely disconnected to dress up in parade uniform, and start to carry a bone on your shoulders.

?Blessed? Michael Sopocko might have put his finger into a lot during his lifetime. That one of his fingers has been cut of from his skeleton is yet another example of the how the bone collectors of Rome has looted corpses.

It is not so strange that Catholics wants to adore more than just a cut off finger. Inside the Shrine it will be entertained by a piece of a ?holy toe?

Was this toe just axed off, or did the priest take a big bite?

The ServiceMagic Connection | Keeping Your Pets and Home Safe

For all the joy our pets bring us, taking care of them can be a lot of work. However, there are ways you can decrease the amount of work your pets require.

Aside from giving pets plenty of love and attention, make sure your home is a safe place for them to patter around. Prepping your home for any potential damage your four-legged companions might cause can not only protect them, but also minimizes damages to your home.

Here are a few tips for keeping your home pet-compatible:

1. Cover any exposed wires. If your pet likes to chew, this tip is for you. Buy cord covers for any wires that run along the floor or in places your pet is likely to explore. Here?s a DIY eco tip: use old paper towel or toilet paper rolls to weave cords through and hide them behind furniture to prevent not only tangling, but curious pets.

While it is definitely a nuisance when dogs chew through cables, it is their health that can be at risk. If your puppy is a chewer, consider investing in some dog insurance so he/she is protected in case of electrocution. There are also cat insurance options available if your kitten is the wire-tampering culprit.

2. Use a foot-pedal trash can. Let?s face it: Without a barrier, many dogs and cats will eat out of the garbage.

Aside from leaving a mess in your kitchen, there could be things in the trash can that are bad for pets. Go for the foot pedal, and nip that problem in the bud.

3. Arrange furniture strategically. Don?t want your cat to jump on the mantle? Worried she will knock over those crystal glasses on the dining room hutch?

Make sure there is nothing around that your pet can climb on that would compromise the safety of any valuable possessions. Keeping these items safe should be as simple as arranging furniture so that there is no way your pet can jump or climb where she doesn?t belong. Be particularly mindful of tall bookshelves that are near standing lamps and curtains.

4. Hide poisonous chemicals. Just like with a child, ingesting harmful cleaning products and chemicals is harmful to your pet. One option is to only purchase eco products that aren?t harmful to animals. If this isn?t feasible, make sure to keep products out of reach of curious pets. This includes putting child locks on lower cabinets and always storing medications and smaller products out of reach in closets and medicine cabinets.

If gardening is your thing, here is a pet-friendly gardening product guide outlining pet-safe products for those that like to exercise their green thumb.

In the event that your pet does ingest something that makes him sick, call your local veterinarian right away. Many pet insurance plans cover accidental poisoning, so make sure you know which veterinarians in your area are covered by your insurance and keep the number handy.

5. Screen your windows. Not only can this let in bugs that could be harmful to your pet (think ticks, bees, mites, etc.), but it can also allow animals to escape. Cats, in particular, are known to be attracted to windows of tall buildings in a phenomenon called high rise syndrome. So if you live in a tall apartment or condo building, install screens to keep your animals safe.

6. Create a pet area. Assuming you have the space, why not create a pet-friendly ?zone? complete with dog or cat doors? If possible, pick a room with a hardwood or tile floor to minimize damage from their nails and allow for easy accident cleanup. Otherwise, try to find carpet that is the same color as your pets? fur so their hair doesn?t show too much.

While pet-proofing your home is a necessity when you keep an animal companion, it doesn?t have to be expensive or even all that time-consuming. Keep these tips in mind, and you?ll create an environment that?s safer for your pet?not to mention your home.

Samsung says to merge bada mobile OS with Intel-backed Tizen (Reuters)

SEOUL (Reuters) ? Samsung Electronics Co said on Tuesday it planned to merge its 'bada' mobile software with a platform backed by chipmaker Intel Corp in its latest push to diversify away from Google's Android.

Samsung, which emerged as the world's biggest smartphone manufacturer on the back of booming Android models in the third quarter, joined forces with Intel last year to strengthen its mobile software push.

In September two Linux software groups, one backed by Samsung, and another by Intel, agreed to jointly develop Tizen, a new operating system for cellphones and other devices, by merging their LiMo and Meego platforms in a bid to gain wider industry and consumer support.

"We have an effort that will merge bada and Tizen," a Samsung spokesman confirmed senior vice president Kang Tae-jin as telling Forbes magazine in an interview last week.

The open-source Tizen platform supports multiple devices including smartphones, tablets, Internet-enabled TVs, netbooks and in-vehicle infotainment systems.

It would have to attract wide support from developers and manufacturers to compete with the dozen or so other mobile operating systems available in a smartphone market dominated by Google's Linux-based Android and Apple's in-house software.

Google's Android accounted for 53 percent of the global smartphone market in the third quarter and Samsung's bada platform just 2.2 percent.

GoBandit WiFi helmet cam hands-on

Extreme sports junkies are no strangers to the vast selection of helmet cams just waiting for them to record their wicked shenanigans, so we were expecting to see nothing drastically new when we stopped by the GoBandit booth at CES 2012. There was one thing, however, that stuck out to us as we played with the company's top-tier model, the GoBandit Live: WiFi. And let's be very careful with words here, because these full HD cams don't find WiFi hotspots -- they are WiFi hotspots. This means that not only can you upload your vids to another device, you can broadcast them live. Here's how it works: download the companion iOS app (the company's working to have Android compatibility soon), activate the cam's WiFi and either load your vids or view them live. The model GoBandit had on hand was still a prototype model, so unfortunately we weren't able to put it to the full test yet, though we at least were able to snap a few pics for the gallery below. Available in March, it comes in two flavors: the Live, which offers GPS and WiFi, and the Race, which doesn't. The pair will go for $419 and $319, respectively.

Surprising results from smoke inhalation study

Loyola University Health System

MAYWOOD, Ill. -- A Loyola University Chicago Stritch School of Medicine study includes some unexpected findings about the immune systems of smoke-inhalation patients.

Contrary to expectations, patients who died from their injuries had lower inflammatory responses in their lungs than patients who survived.

"Perhaps a better understanding of this early pulmonary immune dysfunction will allow for therapies that further improve outcomes in burn care," researchers reported.

The study is published in the January/February issue of the Journal of Burn Care & Research. First author of the study is Christopher S. Davis, MD, MPH, a research resident in Loyola's Burn & Shock Trauma Institute. Corresponding author is Elizabeth J. Kovacs, PhD, director of research of the Burn & Shock Trauma Institute.

Researchers followed 60 burn patients in Loyola's Burn Center. As expected, patients with the worst combined burn and smoke-inhalation injuries required more time on the ventilator, in the intensive care unit and in the hospital. They also were more likely to die, although this finding fell just short of being statistically significant.

Also according to expectations, patients who died were older and had larger injuries than patients who survived.

But the immune system findings were unexpected. Researchers measured concentrations of 28 immune system modulators in fluid collected from the lungs of patients within 14 hours of burn and smoke-inhalation injuries.

These modulators are proteins produced by leukocytes (white blood cells) and other cells, including those that line the airway. Some of the modulators recruit leukocytes to areas of tissue damage or activate them to begin the repair process that follows tissue injury.

Based on studies conducted at Loyola and other centers, researchers had expected to find higher concentrations of modulators in patients who died, because sicker patients tend to have more active inflammatory responses. But researchers found just the opposite: patients who died had lower concentrations of these modulators in their lungs.

Why do some patients mount robust immune responses in the lungs while others do not? The reason may be due to age, genetics, differences in patients' underlying health conditions or anything that might disrupt the balance between too much and too little inflammation, Davis said.

Survival of burn patients has significantly improved since the 1950s, due to advancements such as better wound care and improved prevention and treatment of infections. But progress has somewhat stalled in the last 10 years.

The immune response to injury "remains incompletely understood and additional effort is required to further improve survival of the burn-injured patient," researchers wrote.

The study was presented at the 2011 meeting of the American Burn Association, where it won the 2011 Carl A. Moyer Resident Award for the best study submitted by a resident physician.

Other co-authors of the study are Richard L. Gamelli, MD, FACS, director of the Burn & Shock Trauma Institute; Joslyn M. Albright, MD, chief resident in the Department of Surgery; Stewart R. Carter, MD, research resident; Luis Ramirez, BA, laboratory technician; and Hajwa Kim, MA, MS. All are from Loyola except Kim, who is at the University of Illinois at Chicago.

The study was funded by grants from the National Institutes of Health, Department of Defense, International Association of Fire Fighters and the Dr. Ralph and Marian C. Falk Medical Research Trust.

Loyola's Burn Center is one of the busiest in the Midwest, treating more than 600 patients annually in the hospital, and another 3,500 patients each year in its clinic. It is one of only two centers in Illinois that have received verification by the American Burn Association.

The study is among the results of research over the last several years conducted in Loyola's Burn Center and Burn & Shock Trauma Institute, which is investigating the lung's response to burn and inhalation injuries.

Todd Palin Endorses Newt Gingrich, but Does Anyone Care? (ContributorNetwork)

COMMENTARY | Take a breath everyone. International Business Times reported that Todd Palin has endorsed Newt Gingrich. I know -- for many undecided voters a high-profile endorsement such as this is sure to help them make up their mind to not vote for Mitt Romney after all. And, in case it helps, my brother's next-door neighbor's cousin's uncle is also voting for Gingrich.

It's hard to imagine a less newsworthy story than Todd Palin making an endorsement. The same effect could be achieved by grabbing the next person to walk down the sidewalk and asking them. Todd Palin is a nobody is the grand scheme of politics. In fact, his wife isn't much better these days -- but she's at least keeping any endorsement to herself. Well, that is until she can turn it into a book or speaking tour.

Now, don't get me wrong: I have nothing personal against Todd Palin -- or Sarah for that matter. It's just that I don't think a public announcement by either makes a bit of difference. It's hard to imagine that there is a whole bunch of voters sitting at home wondering just who Todd Palin is going to vote for in order to make up their own mind. It would be nice if voters would study the candidates and come to a conclusion based upon an educated process. That's asking a lot of a nation that barely bothers to go to the polls in the first place.

I'm personally on the Jon Huntsman bandwagon. I don't think it's going to be a long trip -- unfortunately -- but I like the guy and I like what he's talked about. I like the fact that Huntsman knows the Chinese, he's educated, articulate, and will adopt a more even-keel bipartisan approach than any other candidate standing on the stage.

I'm glad the former First Husband of Alaska didn't pick someone like Ron Paul -- that would be a recipe for disaster. It's not the Paul is wrong on the issues, because he's right on many. But his followers are so fanatical that they've forgotten the rights of others to disagree, and that's a fundamental right of all Americans -- especially during an election year. Need proof? Check the comments below in a day or two.

I need a news story for tomorrow: Who's your sister-in-law's aunt's neighbor endorsing?

HBT: 'Nothing going on' with Garza-Tigers talk

Last night David Kaplan of CSNChicago.com reported that the Cubs and Tigers were ?down the road in discussions? for Matt Garza, but today several sources contradict that claim.

Jason Beck of MLB.com reports that ?there?s nothing going on with the Tigers in regards to Garza? and Peter Gammons said on MLB Network that ?I?m told it?s not going to happen.?

Pitching prospect Jacob Turner was believed to be the centerpiece of the deal from the Cubs? point of view, but Beck speculates that they may be holding out for third base prospect Nick Castellanos as well.

In which case a deal seems very unlikely, because Gammons reports that the Tigers ?won?t even do Turner for Garza.?

Green gleam helps fish see violet

Fish's eyes apparently glow to pick up hard-to-detect hues

Web edition : 10:17 am

CHARLESTON, S.C. ? The greeneye fish views its stygian home through fluorescent lenses that turn one color into another, researchers propose, making glowing green images of hard-to-see violet objects.

?Crazy? is what Yakir Gagnon of Duke University cheerfully called the fish-vision idea he and his colleagues presented January 4 at the annual meeting of Society for Integrative and Comparative Biology. Fluorescent materials known to science so far, he explained, respond to incoming light by glowing in a different color in all directions. Yet lenses on the bulging, upward-looking Chlorophthalmus fish appear to have materials that direct that fluorescent glow in the same direction and pattern as incoming light.

Like many deep-sea fishes, greeneyes have only one kind of light-detecting pigment in the retina, the surface at the back of the eye that catches images. That pigment is optimized to pick up a particular wavelength of green light. Alone, the pigment doesn?t even detect blue-violet light.

Yet greeneyes? fluorescent, glowing lenses appear to translate blue-violet light into a more detectable green color. The Duke team has found that incoming blue-violet light (with a short wavelength of 410 nanometers) zaps lens substances into fluorescing a blue-green that?s just a twinkle away from the color the retinal pigment sees best. The lens glow peaks mostly at 485 nanometers, and the retinal pigment picks up light best at 488 nanometers.

Even light made fish-visible might not be so fish-useful if it?s just a blur. Yet the fish lens appears to cast its glow mostly in the same direction that incoming light is traveling, raising the possibility that it?s transmitting something like a fluorescent image, Gagnon said.

The first hint of this came from work by Alison Sweeney, now at the University of California, Santa Barbara, who removed a greeneye?s lens and aimed light at it through a pattern of slits. Capturing what the lens would have projected on the retina, Sweeney found the lens produced a blue-green glow in roughly the same pattern as the incoming light.

Even when ground up into soup, the lens material somehow still cast its glow in particular directions, Gagnon reported. Blue-violet light aimed at a laboratory container of lens material excited a glow directed out the opposite side, as if the shaft of light had just traveled through the soup.

Just how a fluorescent substance might preserve light direction is itself extremely blurry. ?This is all too new,? Gagnon said.

What he did say, though, was that the sea does hold violet things a greeneye might like to see. Reports place the fish from about 50 meters to 1,000 meters deep, where plenty of creatures flash lights in the blue-violet range to attract prey or mates or scare away predators.

?Really neat,? said Geoffrey Hill of Auburn University in Alabama, who studies colors in birds. Biologists have argued that fluorescence in birds, such as the glow-power of budgerigars? heads, benefits the animals. So far, Hill said, the argument for benefits from the fluorescent fish lens looks tighter.
