HBT: Young works out for Phillies

Dmitri Young?s comeback hasn?t found a home yet, but Jim Bowden of ESPN.com reports that the 38-year-old recently worked out for the Phillies.

Young hasn?t played in the majors since 2008, so it?s a long shot, but hitting was never the reason for his demise and he?s dropped 75 pounds.

According to Bowden the Phillies were impressed by Young?s workout, but there?s no word yet if they?re interested in actually signing him to what would presumably be a minor-league contract.

In the meantime he?ll continue to eat one piece of pecan pie and ?call it a day.?

Dr. Phil interviews parents of missing KC baby (omg!)

KANSAS CITY, Mo. (AP) ? The family of a missing Kansas City baby has taped an appearance on the "Dr. Phil" show.

Viewers can tune in Friday to watch the interview with Lisa Irwin's parents and a private investigator who's searching for her.

Lisa was reported missing Oct. 4 when her father, Jeremy Irwin, came home from work around 4 a.m. and couldn't find her. Irwin and Deborah Bradley say they think someone broke into the house and took their daughter.

Deborah Bradley has said police have accused her of being involved in Lisa's disappearance. In tearful statements to the media early on, Bradley has repeatedly insisted she doesn't know what happened to her child.

No suspects have been named, despite an intensive search.

Chris Weidman takes UFC on Fox 2 decision

CHICAGO -- On 11 days notice, Chris Weidman took a less-than-stellar split decision over Demian Maia. The judges saw it 29-28, 29-28, 29-28 for Weidman at the United Center on Saturday night.

Though both men are accomplished grapplers, the first round started with nothing but stand-up. Neither fighter truly got an edge in striking, though it was Maia who got the first takedown. The two got back to their feet quickly, and Maia followed up with aggressive strikes.

Weidman got the takedown to start the second round, but again, they did not stay there for long. Maia's face started to show damage from the repeated hits Weidman delivered, but Weidman's movement around the cage slowed as the round went on. As Weidman slowed, Maia delivered more kicks and punches. Weidman tried for a takedown with a minute left, but Maia easily avoided it. In the final 20 seconds, Weidman was able to get the takedown, and turned over for a choke, but the round ended before he could secure it.

Weidman returned to the clinch in the third round, moving towards Maia and landing knees and punches. They continued their evenly matched striking fest, though both fighters were clearly exhausted.

The crowd in Chicago wasn't enthused about the action, but that's what happens when two grappling aficionados decided to engage in a fist fight.

UPDATE: After the bout, UFC president Dana White tweeted that the scores were read wrong. Weidman actually won by a unanimous decision.

"The Artist" director Michel Hazanavicius wins DGA award (Reuters)

LOS ANGELES (Reuters) ? "The Artist" director Michel Hazanavicius was named the year's best feature film director by the Directors Guild of America on Saturday, further positioning the silent movie-era romance as a frontrunner for Oscars.

The movie about a fading star whose career is eclipsed by the woman he loves just as talkies are putting an end to silent pictures has been a critical darling throughout the Hollywood's current awards season.

"This is really touching and moving for me," said French director Hazanavicius upon accepting his award at the Grand Ballroom adjacent to the Kodak Theatre where the Oscars, the film industry's highest honors, will be given out on February 26.

"It's maybe the highest recognition I could hope for," he said.

The DGA Awards are a key indicator of who may win Academy Awards next month because only six times since the DGA began handing out annual honors in 1948 has the its winner failed to also be named best director by Oscar voters.

More important, there is a long history among members of the Academy of Motion Picture Arts and Sciences, which gives out the Oscars, to give their Academy Award for best film to the movie made by the winner of best director.

The next stop in the race for Oscars is Sunday's Screen Actors Guild awards in Los Angeles where "The Artist" will look to extend its streak of victories, including a Golden Globe for best film musical or comedy and honors from critics groups.

The DGA also gives out other awards, including one for best film documentary, which went to James Marsh for "Project Nim."

Among TV award winners, Patty Jenkins was given the DGA trophy for best drama series for the pilot episode of "The Killing" and Robert B. Weide took home the DGA award for best comedy series for an episode of "Curb Your Enthusiasm."

Outrage as bodies pile up at Cook County morgue

Cook County officials say they are being forced to change morgue procedures due to an overflow of unclaimed bodies. Charlie Wojciechowski reports.

By Dick Johnson and Michelle Relerford, NBCChicago.com

CHICAGO ? Outraged pastors and community activists on Friday descended upon the Cook County Medical Examiner's Office and called for an independent investigation after reports that bodies have been piling up for weeks.

At least one activist openly called for the facility's director, Dr. Nancy L. Jones to step down.

"Somebody needs to be held accountable for what happened," said Dawn Valenti, who works to help families find missing loved ones.

Read original story at NBCChicago.com

Cook County Board President Toni Preckwinkle a day earlier said Jones will remain -- for now -- but called for a top-to-bottom review of the facility.


"This is a reminder of how my ancestors -- how the remains of our ancestors were treated like garbage," Peggy Hudgens said through tears at the building at 2121 W. Harrison St.

Hudgens claimed to have been trying to resolve her brother's death and burial since October.

The issue has been simmering for months, if not years. As many as 363 bodies were reportedly once collected in a cooler designed to hold just 300. Ministers gathered Friday to pray for the deceased and to call for justice.

Anti-violence community activist Andrew Holmes was among the protesters and wondered aloud about the accountability of missing persons at the morgue.

"We want those deceased finger-printed and identified. We still have a lot of missing, unclaimed and missing people that have not been found," he said.

Holmes focused specifically on Carmelita Johnson, a woman who'd gone missing and was ultimately found in the facility. Her family said they tried to find her for more than a year. Johnson has since been buried.

The Illinois Department of Labor said it's also opened an investigation into "worker safety issues."

Nintendo gets with the times, announces Nintendo Network, DLC, and NFC for Wii U (Digital Trends)

Wii-u
After a decade of lackluster online support, Nintendo may finally be wising up. During an investor?s briefing today, Nintendo President Satoru Iwata announced that its upcoming console, the Wii U, will have two new features: NFC built into the controller and an Xbox Live-like online service called Nintendo Network. Downloadable content, including fullly downloadable retail games is also a possibility. Details below.

Wii U to have a solid launch in 2012

Iwata began his discussion about the Wii U by stating that it will launch in the United States, Japan, Europe, and Australia in time for the holiday sales season this year. 

?The company is aiming to firmly complete the development of the entire system and prepare sufficient software so that the Wii U will be at its best at the time of the launch,? said Iwata. ?Needless to say, we have learned a bitter lesson from the launch of the Nintendo 3DS.?

NFC in Wii U controller

NFC has been hailed as the next big thing in mobile credit card and payments technology. It enables you to safely transfer data between two objects safely and securely by hovering them about 0-3 inches apart. Google has been one of the biggest early supporters of the technology, building its Google Wallet service around it, which allows you to use your Android phone as a credit card of sorts. Android 4.0 also has a new feature called Android Beam, which lets you exchange almost any information between two NFC equipped Android devices by tapping them together. The feature is a novelty, but pretty cool to experience.

Nintendo has similar plans. Iwata announced that the giant Wii U controller will be NFC enabled, opening up loads of possibilities for the new console. Iwata said that the new system could be used to make micropayments or for tapping cards on your controller to submit game data to the Wii U. Nintendo has done this before. Back in 2001 it launched the Game Boy Advance E-Reader, a peripheral that plugged into the handheld like a game cartridge and used credit card magnetic swipe technology to transfer tiny bits of data from paper game cards to the handheld. It never really took off outside of a few games, but it sounds like Nintendo may be resurrecting the idea using NFC. This will let Nintendo sell or give away physical items and let players add those items directly into a game.?

The possibilities of this technology are far greater. Nintendo has said that the Wii U controller can be used as a multiplayer game surface before. Well, what if the controller sat in the middle of a table and 3-4 players were able to play a board-like game together, but also use the Wii U in different ways by tapping their cards on the controller? This could really make certain board games a lot more fun, if implemented right.

It could also, as Iwata mentioned, make micropayments a lot easier. Currently, if you want to purchase something in the Wii Virtual Console store, you have to first buy Wii Points by entering a credit card (and you have to completely re-enter it every time) or by purchasing a Wii Points card at a store like GameStop or Best Buy and then typing in a long numerical code on them into your Wii. Using NFC, future Wii U Points cards could automatically add their balance to your Wii U account without having to enter anything. You?d just have to tap them to your console and press ?Yes, I?d like to add these funds to my account.?

The Nintendo Network

Nintendo has always been one of the most innovative and stubborn video game companies. It has reinvented itself and the gaming world more than once, but continually refuses to adapt to trends that it doesn?t create. A good example of that has always been online play. The Kyoto game maker has been dipping its feet into the online world as far back as 1987 (read:?a history of Nintendo?s online activities). Its plans weren?t all vapor either. It created a full add-on for the Nintendo 64 designed around an online network, but the concept was never successful enough to leave Japan. Other endeavors in the 90s failed to take off either, so when the Sega Dreamcast and Microsoft Xbox both began to make waves a little over a decade ago, it was not surprising that Nintendo was reluctant to get onboard with online gaming. It could be a fad, after all. The Wii also got away with having no decent online support either due to the massive success of its new controller, but Nintendo?s recent struggles have forced it to reconsider. ?

A mere decade behind the competition, Nintendo is also finally launching the Nintendo Network, which will be available on both the Nintendo 3DS and Wii U. The system will be a full online network with actual personal accounts for each user and online communities (like the one in Mario Kart 7). On the Wii and DS, Nintendo does not allow individual user accounts like Xbox Live or PlayStation Network. Instead, users can only play together by trading long numerical codes attached to their consoles. Because of this, the Wii and DS online presence has been muted.

Iwata did not specifically say, but we speculate that the Nintendo Network will somehow incorporate or honor purchases made on the Wii Shop Channel and 3DS eShop.

Downloadable content (DLC) will be available for the Wii U as it has the Nintendo 3DS as well, said Iwata. However, he made sure to point out, as he has in the past, that Nintendo has no plans to mimic the business model of social games like FarmVille that claim to be free but then try to milk money out of users.?

?While we are on this subject [of downloadable content],? said Iwata, ?when we discuss anything relating to add-on content, our remarks are very often reported by the media by their attaching such modifiers or notes as ?the ones used for social games.? Please note that Nintendo, as a software maker, does not plan to deploy businesses where our consumers cannot know in advance which item will appear as the result of their payment and they have to repeat the payments and, before they know it, they end up spending a huge amount of money in order to obtain the items they originally wanted to purchase. As a software maker, Nintendo believes that its packaged software should be sold to our consumers in a form so that the consumers will know in advance that they can enjoy playing the software they purchased just as it is. We believe that our consumers will be able to feel more secure if we offer our add-on content as an additional structure in which those who love the game will be able to enjoy it in a deeper way for a prolonged play time.?

Full downloadable retail games coming, someday

While it doesn?t sound like it will happen immediately due to pressure from retailers who need boxed software to keep their doors open (GameStop, Best Buy), Iwata says Nintendo is ready to sell full games via download as well. Both the 3DS and Wii U will be capable of this. Another potential hurdle is that the the game maker still plans to rely on SD cards as the main way for customers to store purchased content and game saves. This is a far different approach than Microsoft and Sony are taking. Both the Xbox 360 (most of its models) and PlayStation 3 are equipped with large hard drives for storing downloadable games. However, neither company has announced plans to move sales of full retail titles to the Internet either, likely due to the same reasons and that it would take users a very long time to download games, which will likely be 5-50GB a piece in the next generation of consoles.

Good news all around

If you?re a Nintendo fan, today is a good day. While we still haven?t seen the Nintendo Network, from the sounds of it, the service will be a vast improvement to anything offered on the Wii or GameCube. Hopefully, it will also have a robust apps store that allows for open development and has features like saving games to the cloud. There?s nothing quite as scary as losing all of your game saves.?

We still have our doubts about the Wii U (read our CES impressions), but Nintendo might finally nail the online experience.?

Forests for all? New federal rule aims to please

Siskiyou Project via AP file

National forest uses include logging like this work in Oregon's Siskiyou National Forest. Trying to balance resource use and resource protection has been controversial.

By Miguel Llanos, msnbc.com

It's no easy task figuring out how to balance forest and wildlife protection with logging, drilling and offroading on the nation's 155 national forests, but the Obama administration on Thursday unveiled a rule it says will do just that. An era of collaboration and less litigation was promised with the rule managing forests, but some initial reaction?by interested parties -- which range from environmentalists to loggers to offroaders -- was not promising.

"Our preferred alternative will safeguard our natural resources and provide a roadmap for getting work done on the ground that will restore our forests while providing job opportunities for local communities," U.S. Agriculture Department chief Tom Vilsack vowed in a statement.


The rule essentially revises the existing framework for how each forest's managers must proceed with a given issue -- be it a request to log, a request to protect some species or even a request to open part of a forest to offroad vehicles.

The U.S. Forest Service, which?is part of USDA, last year issued a draft of?the rule for public review. That process generated more than 300,000 comments that Vilsack said were weighed and, in some cases, incorporated into the final rule.?

Unlike national parks, which protect resources, national forests were created to balance resource protection with resource use but that still hasn't prevented decades of legal battles.

"We expect to see much less litigation because of the increased collaborative effort" in deciding what happens in each forest, Forest Service Chief Tom Tidwell told reporters.

Officials noted that several changes were made to the draft, including adding emphasis on "sound science" and, according to Tidwell, "beefed up protection of water resources."

Tidwell said the rule would also streamline how each national forest is managed, which will free up "more time, more money to get the restoration done" across the 193 million acres of forest.

The Natural Resources Defense Council had a mixed initial take on the rule. "It is much more meaningful about getting local officials to apply the best available science," NRDC forest analyst Niel Lawrence told msnbc.com, and there's "significant improvement in public participation."

But the environmental group is also "very concerned" because the rule removes a provision ensuring that wildlife will have viable populations distributed across the forests where they are now found, Lawrence said. "It jettisons the single most important conservation protection" on U.S. forests over the last 30 years, he added.

The NRDC intends to lobby the administration and if that doesn't work a lawsuit is "perfectly possible," Lawrence said.

A timber industry group, for its part, told msnbc.com that it needed a day or two to review the rule. But, in a statement?issued right after the rule, the?American Forest Resource Council voiced concern.?"We are very concerned about whether the agency took the comments we made on the draft rule to heart and made changes needed to avoid the mistakes of the past," said council President Tom Partin.

The BlueRibbon Coalition, a group representing offroad interests, also said it was still reviewing the rule.

In Congress, the chair of the House Natural Resources Committee, Washington state Republican Doc Hastings, said the concerns he'd raised earlier "fell on deaf ears."

"These new Obama regulations introduce excessive layers of bureaucracy that will cost jobs, hinder proper forest management, increase litigation and add burdensome costs for Americans," he said in a statement.

Last November, Hastings' committee hosted a hearing where critics piled on against the draft rule.

"First, the proposed planning rule will increase the complexity, cost, and time for the Forest Service to complete forest plans," testified Scott Horngren on behalf of the American Forest Resource Council. "Second, of greater concern, is that the planning rule will make the projects that implement the plans more vulnerable to lawsuits than they are today."

The last time the planning rules were updated was in 1982. Several attempts to revise it have been thrown out by federal courts. In 2009, a Bush administration plan was struck down. Environmentalists had fought the rule, saying it rolled back key forest protections.

The Obama administration decided not to challenge that ruling and instead come up with new rules.

Parent of Obama-backed battery maker goes bankrupt (AP)

WASHINGTON ? The parent company of an electric car battery maker that received a $118 million grant from the Obama administration has filed for Chapter 11 bankruptcy protection.

Ener1 said it has been affected by competition from China and other countries.

Ener1 subsidiary EnerDel received a $118 million stimulus grant from the Energy Department in 2009, and Vice President Biden visited the company's new battery plant in Indiana last year.

An Energy Department spokeswoman said EnerDel had received $55 million so far. Ener1 said the restructuring would not affect EnerDel's operations.

Ener1 is the third company to seek bankruptcy protection after receiving assistance from the Energy Department under the economic stimulus law. California solar panel maker Solyndra Inc. and Beacon Power, a Massachusetts energy-storage firm, declared bankruptcy last year.

Mandy Moore: Listen Up, Davos: Global Health is Good for Business

It's around 25?F in Davos, Switzerland today. Thousands of world leaders have arrived for the World Economic Forum (WEF) Annual Meeting. These powerful men and women will spend the next five days setting a course for 2012.

As an ambassador for the global health organization PSI and a member of the WEF Global Shapers, I am really following what's going on there, primarily because it includes a significant number of young leaders who will add their ideas on strengthening the global economy.

I am really hoping that the leaders of the world's most powerful companies walk away understanding the economic importance of global health. And that they make improving global health part of their business plans.

I can't fathom that 2 to 3 billion people live in poverty - many in the developing world, where access to basic health care is limited. I recently read that the poorest two-thirds of the world's population has a US $5 trillion purchasing power. So, with simple investments in the delivery of basic health products and services, people struggling to survive can become more active consumers and producers.

New markets for goods (including American products) will develop, economies will become more vibrant and profits will rise. Most importantly, mothers will be healthier and children will regularly attend school. It really is a win-win.

The U.S. Congress understands this.

On December 23, as the rest of us were finishing up last minute holiday shopping, President Obama signed into law the "Consolidated Appropriations Act of 2012." Really, this long-winded title should be renamed: "The Other Jobs Bill."

All year, Republicans and Democrats had been discussing ways to improve the American economy and create jobs. With the bipartisan appropriations bill, Congress "put its money where its mouth is." The bill increased U.S. global health aid for 2012. Other aspects of foreign aid were reduced - but global health went up. This is because Congress understands the many benefits of American investment in global health.

Government support alone can't solve global health epidemics like malaria, HIV, unsafe drinking water and maternal mortality. Corporate involvement and investment is essential.

That's why these discussions at Davos and the subsequent actions are so important. It's an amazing opportunity for health organizations like PSI to link arms with companies such as Unilever and Procter & Gamble in the fight to improve drinking water and expand hand washing.

In such trying economic times, the need for all of us to work together is greater than ever.

And I really believe Davos is the perfect place to start.

A year after uprising, Egyptians celebrate and protest (Reuters)

CAIRO (Reuters) ? Tens of thousands massed in Cairo's Tahrir Square and other Egyptian cities on Wednesday, a year after an uprising erupted that toppled Hosni Mubarak, spurred on revolts across the region and exposed rifts in the Arab world's most populous state.

United last year by popular anger at Mubarak and his 30-year rule, Egyptians gathering on the January 25 anniversary were in high spirits but divided between activists demanding a swift end to army rule and Islamists celebrating their dramatic change in fortunes after emerging victors in a parliamentary election.

One group of mostly youths in Tahrir stood near a street where protesters clashed in November and December with police and the army, chanting "Down with military rule" and "Revolution until victory, revolution in all of Egypt's streets."

With the 83-year-old Mubarak on trial for his life but a new parliament installed this week that is dominated by his Islamist adversaries, some of the youthful activists who turned to the Internet to launch last year's revolt are disenchanted, weary of army rule but fearful the Islamists may also stifle their hopes.

Protesters mistrust the military council that took charge on February 11 last year when Mubarak was driven out and which is led by his defense minister for two decades, Field Marshall Mohamed Hussein Tantawi. The army has vowed to relinquish power after a presidential poll in June.

At the other side of Tahrir, a vast plaza where protesters fought fierce battles with police during the 18-day uprising last year, supporters of the once banned Muslim Brotherhood and other Islamists grouped to celebrate.

"I'm very happy with the anniversary of January 25. We never dreamed of this. The revolution's victory was reaped with the elected parliament," said Khaled Mohamed, 41, a member of the Brotherhood whose Freedom and Justice Party (FJP) secured the biggest bloc in parliament after the first free vote in decades.

A member of the Brotherhood's party now sits on the speaker's chair, an idea unimaginable a year ago when the lower house was a compliant, rubber-stamp body stuffed full of Mubarak's supporters. The assembly also has a strong contingent of ultraconservative Salafi Muslims.

However, some liberal activists fear the Brotherhood and other Islamists are colluding with the army to entrench their position in mainstream politics at the expense of a deeper purge of the old order. Islamists dismiss talk of any such alliance.

The United States, a close ally of Egypt under Mubarak, praised "several historic milestones in its transition to democracy" this week, including the convening of parliament.

"While many challenges remain, Egypt has come a long way in the past year, and we hope that all Egyptians will commemorate this anniversary with the spirit of peace and unity that prevailed last January," a White House statement said.

AUTOCRATIC WAYS

But pro-democracy activists doubt the army's intentions and fear it wants to cling on to power from behind the scenes even after a president is elected. Some cast envious glances toward Tunisia, whose successful revolt last January inspired the Egyptians and which has now moved directly to civilian rule.

The activists in Egypt point to a surge in military trials of civilians and the use of violence against protesters as signs of autocratic ways similar to three decades under Mubarak.

When the army was ordered onto the streets after days of clashes with police during the uprising, the troops were hailed and cheered. Many Egyptians have since watched in horror as soldiers have dragged, beaten and fired tear gas at demonstrators demanding that the army return to its barracks.

Tantawi defended the military during a televised speech on Tuesday: "The nation and the armed forces had one aim: for Egypt to become a democratic state," he said.

Along with demonstrations in Cairo, Egyptians also gathered in the northern city of Alexandria and in Suez, scene of some of the fiercest violence during the revolt and also the place where the first death was reported during the uprising.

"We didn't come out to celebrate. We came out to protest against the military council and to tell it to leave power immediately and hand over power to civilians," said Mohamed Ismail, 27, in Suez, a port city east of Cairo.

There were no official numbers for Wednesday's turnout. But some witness estimates put the number in Tahrir at 150,000 or more although there was a constant flow of people in and out of the square. Thousands were also out in other areas of Cairo.

Demands for justice for the "martyrs of the revolution" was one of the unifying calls for all demonstrators on Wednesday. Banners with pictures of those killed in the uprising were hung from lamp-posts in Tahrir.

Many are angry that no one has yet been found responsible for the deaths of 850 people during the uprising. A trial of Mubarak, his interior minister and others officials continues.

"Martyrs, sleep and rest. We will complete the struggle," chanted protesters in Alexandria.

Despite unity on that issue, there were signs of friction even late on Tuesday as people began congregating in Tahrir, pitching tents in winter rain.

"The military council is Mubarak," said Amr al-Zamlout, a 31-year-old protester clutching a sign declaring "there is no change" and stating his aim was to topple the army rulers.

Mohamed Othman, an accountant, stopped to put forward a different view based on the idea that Egypt needs stability for economic recovery, not more protests: "The council will leave power in any case. Sure, the revolution is incomplete, but it doesn't mean we should obstruct life," he said. His criticism quickly drew a crowd and touched off an argument.

In an apparent attempt to appease reformist demands, the military council has in recent days pardoned some 2,000 people convicted in military courts since Mubarak was deposed. On Tuesday it announced a partial lifting of a state of emergency.

But it kept a clause saying emergency laws in place since 1981 would still apply in cases of "thuggery," a vague term that triggered calls for clarification from Washington and more criticism from human rights groups.

Environment that nurtures blood-forming stem cells' growth identified

ScienceDaily (Jan. 25, 2012) ? Scientists with the new Children's Research Institute at UT Southwestern Medical Center have identified the environment in which blood-forming stem cells survive and thrive within the body, an important step toward increasing the safety and effectiveness of bone-marrow transplantation.

Institute investigators led by Dr. Sean Morrison asked which cells are responsible for the microenvironment that nurtures haematopoietic stem cells, which produce billions of new blood cells every day. The answer: endothelial and perivascular cells, which line blood vessels.

"Although scientists have searched for decades to identify the stem cell home, this is the first study to reveal the cells that are functionally responsible for the maintenance of blood-forming stem cells in the body," said Dr. Morrison, director of the new institute and senior author of the study available Jan. 26 in Nature. "This discovery will lead to the identification of the mechanisms by which cells promote stem cell maintenance and expansion."

Scientists already have determined how to make large quantities of stem cells and how to change these cells into those of the nervous system, skin and other tissues. But they have been stymied by similar efforts to make blood-forming stem cells. A key obstacle has been the lack of understanding about the microenvironment, or niche, in which blood-forming stem cells reside in the body.

In the first breakthrough from the Children's Research Institute, Dr. Morrison's laboratory addressed this issue by systematically determining which cells are the sources of stem cell factor, a protein required for the maintenance of blood-forming stem cells. His team swapped out the mouse gene responsible for stem cell factor with a gene from jellyfish that encodes green fluorescent protein. The cells that glowed green were endothelial and perivascular cells, revealing them as the creators of the niche that nurtures healthy blood-forming stem cells.

Additional lab work showed that blood-forming stem cells become depleted if stem cell factor is eliminated from either endothelial or perivascular cells. Loss of stem cell factor from both of these sources caused stem cells to virtually disappear.

The research has implications for bone marrow and umbilical cord blood transplants, Dr. Morrison said. If scientists can identify the remaining signals by which perivascular cells promote the expansion of blood-forming stem cells, then they may be able to replicate these signals in the laboratory. Doing so will make it possible to expand blood-forming stem cells prior to transplantation into patients, thereby increasing the safety and effectiveness of this widely used clinical procedure.

Dr. Morrison's paper is the first to emerge from the Children's Research Institute at UT Southwestern, a pioneering venture that combines the medical center's research prowess with the world-class clinical expertise of Children's Medical Center Dallas. Under Dr. Morrison's leadership, the institute is focusing on research at the interface of stem cell biology, cancer, and metabolism that has the potential to reveal new strategies for treating disease.

The institute currently has more than 30 scientists and will eventually include 150 scientists in 15 laboratories led by UT Southwestern faculty members. Dr. Morrison's lab focuses on adult stem cell biology and cancers of the blood, nervous system and skin.

The Nature paper's first author is Dr. Lei Ding, postdoctoral research fellow at the Children's Research Institute and the Howard Hughes Medical Institute. Scientists from the University of Michigan and Cold Spring Harbor Laboratory also contributed to the study, which was supported by the HHMI and the National Heart, Lung and Blood Institute.

Leonardo admits defeat in pursuit of Carlos Tevez

Associated Press Sports

updated 8:57 a.m. ET Jan. 24, 2012

PARIS (AP) -Paris Saint-Germain has failed in its latest effort to recruit a star player, with sporting director Leonardo saying the French club has ended negotiations to sign Carlos Tevez from Manchester City.

After missing out on former England captain David Beckham and AC Milan striker Alexandre Pato, Tevez became PSG coach Carlo Ancelotti's priority signing and Leonardo met with the player's adviser, Kia Joorabchian, in Paris last week.

"We've ended the negotiations. We made a handsome offer but we couldn't reach an agreement," sports daily L'Equipe quoted Leonardo as saying on its website on Tuesday. "So we're stopping. It's over."

Tevez has not played for City since September.

PSG is top of the French league and leads Montpellier by three points, but may now have to wait until the offseason before signing the big name it craves.

"There aren't many opportunities left and we're not going to splash out," Leonardo said. "We're already fine as we are. We have a competitive squad."

Merkel: Only a unified Europe can remain powerful (AP)

DAVOS, Switzerland ? German Chancellor Angela Merkel insisted Wednesday that Europe will remain an economic power only if it deepens the integration that has caused it so many problems. Without that, she warned the global elite gathered in a Swiss ski resort, Europe will remain little more than a pleasant vacation destination.

The tone of Merkel's keynote address was not dramatically different from her measured norm, but it was positive enough to feed an emerging feeling among European power brokers that Germany ? and hence Europe ? is finally becoming convinced that it needs to do whatever it takes to save the euro from collapse.

"The message is that we are ready for more commitment. We are no longer making excuses," Merkel said. If Europe doesn't integrate further, she said, "we will remain an interesting holiday destination for a long time, but we won't be able to produce prosperity for the people in Europe anymore."

Merkel pledged to do what is necessary to protect the euro from collapse, and said greater European unity is needed to spark job creation and growth. However, she poured cold water on calls for Europe to ratchet up the financial firepower of its safety net for failing economies.

Germany is at the center of any rescue plan because it has the deepest pockets in Europe. And Europe is at the center of the global outlook because many fear a collapse of the euro could drag large parts of the world back into recession.

For months, Germany has argued that indebted countries much cut their budgets to the bone, and that their people must become poorer, in exchange for help in reducing their debt loads. But many say that will do little good if that very austerity causes growth to evaporate, making countries unable to pay back the debt that remains.

George Soros, the philanthropist and former financier, called Germany a task master imposing a strict anti-inflationary viewpoint on the rest of the continent. He said weaker eurozone countries have been "relegated to the status of third world countries" having to pay back debts in a foreign currency.

"The problem is that the austerity that Germany wants will push Europe into a deflationary death spiral. ... The economy will contract and tax revenues will fall. So the debt burden ... will actually rise, requiring further budget cuts and setting in motion a vicious cycle."

Merkel's government has been unwilling to back two proposals voiced as potential solutions to the 2-year-old debt crisis: "eurobonds" backed jointly by all eurozone countries, and stimulus that essentially involves getting the European Central Bank to print more money.

In the past month, business leaders and academics say they have become increasingly confident that Germany ? once its back is against the wall ? will go along with measures to boost growth, and possibly save Europe from deeper crisis.

"We are starting to see signs of a shift in sentiment towards Europe," said Baudouin Prot, CEO of French bank BNP Paribas.

He said the catalyst for the newfound optimism was a round of reasonably priced long-term loans to European banks by the European Central Bank, which caused spiking interest rates for European bonds ? a key indicator of confidence in their ability to pay back the money ? to drop.

"We are on the right track, but we need to keep moving forward. We need each country to implement financial discipline," Prot said. "But it's not just about debt reduction. Europe also needs a growth strategy, a series of initiatives to open up the market, support innovation and competitiveness."

He said all 17 countries that use the euro must improve their finances, and that Europe as a whole needs to act better as a whole. He also cautioned against overregulation of banks.

Soros had a gloomier outlook but said he too sees Germany coming around to the idea that austerity is not enough, and that too much of it will just end up making matters worse.

"The argument is really very strong and I believe that it has to eventually sink in," he said.

Soros and others stressed that tough decisions need to be taken and that Europe is far from out of the water. What is changing is that leaders increasingly believe that Europe ? its back against the wall ? is finally acting. In December, the leaders of the 17 countries that use the euro agreed they need new rules that they're now working out, calming markets.

Gerard Lyons, global chief economist at Standard Chartered, said rescue efforts have been misguided.

"Europe is focusing on the wrong problem," he said. "Clearly debt has to be brought down. But Europe suffers from a lack of growth, not a high level of debt. ... Basically you need to address a debt problem by focusing on growth."

Oxford University professor Timothy Garton Ash said there's still a good chance Greece will default on its debt. What matters, he said, is how Europe responds: If it builds an effective firewall to prevent the crisis from spreading to other countries, that would go a long way to calming the fears that have caused so much turmoil.

"I do think there really is a shift in sentiment and perceptions," Garton Ash said. "The market sees that Germany is really willing to do what it takes."

The fear that gripped markets in the second half of 2011 was largely due to concerns that Italy ? the eurozone's third economy ? would default on its debt, and that it would be too big for Europe to bail out. A default by Italy would send massive shock waves round the global economy as well as potentially wiping out large chunks of Europe's banking system.

Amid the discussion of Europe's debt woes came a sense that Western-style capitalism, as practiced for decades, is moving into a new phase. A four-year economic crisis is putting pressure on politicians to build a new model.

David Rubenstein, managing director of asset management firm Carlyle Group, said leaders must work fast to overcome the crisis or see other models of capitalism, such as the form practiced in China, win the day.

"We've got to work through these problems. If we don't do that in three or four years ... the game will be over for the type of capitalism that many of us have lived through and thought was the best type," he said.

China has reaped the rewards of its transition to a more market economy and is now the world's second-largest economy. Unlike the capitalist systems in the U.S. and Europe, China's market transformation has been heavily guided by a state apparatus that continues to balk at widespread democratic reforms. Latin America, too, has seen success in the development of "state capitalism" in certain industries.

"You combine elements of private enterprise with public responsibility," said Colombia's mining and energy minister, Mauricio Cardenas.

At the economic forum, there were numerous references to the need to innovate, the need to consult with employees and the realization that power in the world is shifting from the west to the east. While the traditional industrial economies of the United States and Europe have limped through the last few years, often from one crisis to another, many economies in Asia and Latin America have been booming.

Outside the conference center, activists are camped in igloos to protest years of crisis in which hundreds of millions have lost their jobs even as top executives still reap huge pay packets. On Wednesday they sent aloft big red weather balloons carrying a protest banner reading "Hey WEF, Where are the other 6.9999 billion leaders?"

RIM's new leader raises doubts among investors (Reuters)

TORONTO/LONDON (Reuters) ? The new leader at Research In Motion on Monday dismissed talk of drastic change at the BlackBerry maker, a declaration seized on by impatient investors who say Thorsten Heins has only 12 to 18 months to turn RIM around.

Takeover talk, swirling around RIM for months, picked up steam as Heins took the helm at a once-dominant smartphone company that now struggles to compete. But RIM's shares tumbled more than 8 percent as investors wondered whether Heins could reverse RIM's decline.

"I don't think that there is some drastic change needed. We are evolving ... but this is not a seismic change," said Heins, who joined RIM in 2007 and previously served as a chief operating officer.

RIM's co-CEOs Mike Lazaridis and Jim Balsillie, the men who engineered RIM's rise, resigned on Saturday after intense investor pressure. Their presence had been seen as a big obstacle to a possible sale of the company, although Heins insisted that was not an option he was considering.

Shareholders and analysts have grown impatient in recent months and calls for Lazaridis and Balsillie to step aside had reached a crescendo. RIM has lost market share and market value after being comprehensively outplayed by Silicon Valley tech giants Apple and Google.

"If Thorsten really believes that there are no changes to be made, he will be gone within 15 to 18 months. He will be a transitional CEO and this will be a transitional board," said Jaguar CEO Vic Alboini, who leads an informal group of 16 RIM shareholders calling for a radical restructuring. The group holds a little less than 10 percent of RIM's stock.

Lazaridis and Balsillie - two of RIM's three largest shareholders with more than 5 percent each - will remain board members, while Lazaridis will also head a newly created innovation committee. Their new roles suggest continuity was a goal in the transition.

Critics have called for a new leader who can rejuvenate both the design and operational sides of the business, or prepare it for sale to one of a raft of rumored buyers.

Heins, a former Siemens AG executive, said during a conference call on Monday that he would hone rather than abandon current strategy at RIM, which after years of massive growth needed to start operating like a mature business, not a startup.

The new CEO, who scored his last major promotion as RIM was shedding some 2,000 jobs last June, said no further job cuts were currently planned and that with RIM's $1.5 billion in cash he had no qualms in spending on the right projects.

"If I have a great strategic project or a good business case I can go to the board anytime and ask for approval for additional investment and the money's in the bank to do this," he said.

INVESTORS DISAPPOINTED

Analysts were cautious.

"People may have been a little disheartened that he was defending the current RIM strategy," said Morgan Stanley analyst Ehud Gelblum. "I think (investors) might have wanted to hear a mea culpa."

"People would have been happier hearing 'we are on the wrong path'. We didn't hear a lot of talk about change."

Jaguar's Alboini criticized the retention of Balsillie and Lazaridis on RIM's board and called for several other board members to step down before RIM's mid-year annual meeting.

"If we're wrong, prove us wrong," Alboini said in an interview, referring to the group of shareholders who support his view. "This group is not going anywhere. This is just putting RIM in a position where it might be able to get back into the game. It's early days."

Barbara Stymiest, a former banking and exchange executive, will replace Lazaridis and Balsillie as the chair of the board. Stymiest, a RIM board member for five years, is also viewed as an insider tied to the old regime.

LOOKING AHEAD

Heins' immediate concerns are to generate sales of RIM's current lineup of BlackBerry 7 touchscreen devices, deliver on a promised software upgrade for its PlayBook tablet computer by February, and rally RIM's troops to launch the next-generation BlackBerry 10 phones later this year.

But even if he had a credible overall plan to foster change, some analysts question whether RIM had fallen too far behind its competitors to catch up.

Its existing product lineup has struggled to compete with Apple's iPhone and iPad and the slew of devices from Samsung and others using Google's Android operating system. In North America particularly, RIM has hemorrhaged market share during a year marked by product delays and a botched launch of the PlayBook.

"If RIM's going to grow in the U.S. ... they have to have products better than the iPhone or Android," said Pacific Crest analyst James Faucette. As of now, "they don't have products that are competitive with those, let alone better."

But RIM has also shown a renewed seriousness about getting its message delivered, hiring crisis management firm Sitrick and Company as strategic counsel.

Sitrick helps companies in crisis and celebrities navigating scandal. Clients have included Paris Hilton as she faced jail time and Michael Vick, an NFL quarterback involved in a dog-fighting ring. The firm also helped Roy Disney remove Michael Eisner as chairman of Walt Disney.

SEEKING A PLAN

Analysts circled their calendars for an analyst day in early May as the first opportunity for the new leader to lay out a detailed plan for reversing the decline.

The event "will now become the focal point to the unveiling of Thorsten's vision," CCS Insight analyst Ben Wood told Reuters. "The speed with which you make strategic changes and implement them is absolutely critical because the mobile phone business will not stand still."

"If there are no meaningful signs of an imminent turnaround, then I think the spotlight will turn back on to the assets that RIM holds and who they might be attractive to."

Investors have seized on any rumor of a deal involving RIM as a reason to celebrate, whether talk is of a pact with Amazon as reported by Reuters in December, or with Samsung last week.

Analysts have said logical buyers for RIM also include fellow-struggler Nokia, perhaps with support from Microsoft, and Facebook which is increasingly pushing its content to users via their mobile phones.

If there is no obvious buyer, Heins has more immediate options to add value to the business.

RIM could license its software or integrate its email package, a strategy that many analysts and investors have thought the company might pursue. Heins said it would be wrong to focus on that option but he is still open to discussions.

"RIM have had big challenges in the past and they succeeded in moving from a corporate product to be also a consumer product, to get a foot in the consumer market and very few people expected them to do that," consultant John Strand said.

"Now they have to reinvent themselves again."

RIM's U.S.-listed shares closed 8.5 percent lower at $15.56, for a market capitalization of little more than $8 billion. In the company's heyday, just three and a half years ago, it had a market capitalization around $80 billion.

Easier testing for diabetics? Biochip measures glucose in saliva, not blood

ScienceDaily (Jan. 23, 2012) ? Engineers at Brown University have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could be used to measure a range of biological and environmental substances.?

For the 26 million Americans with diabetes, drawing blood is the most prevalent way to check glucose levels. It is invasive and at least minimally painful. Researchers at Brown University are working on a new sensor that can check blood sugar levels by measuring glucose concentrations in saliva instead.

The technique takes advantage of a convergence of nanotechnology and surface plasmonics, which explores the interaction of electrons and photons (light). The engineers at Brown etched thousands of plasmonic interferometers onto a fingernail-size biochip and measured the concentration of glucose molecules in water on the chip. Their results showed that the specially designed biochip could detect glucose levels similar to the levels found in human saliva. Glucose in human saliva is typically about 100 times less concentrated than in the blood.

"This is proof of concept that plasmonic interferometers can be used to detect molecules in low concentrations, using a footprint that is ten times smaller than a human hair," said Domenico Pacifici, assistant professor of engineering and lead author of the paper published in Nano Letters, a journal of the American Chemical Society.

The technique can be used to detect other chemicals or substances, from anthrax to biological compounds, Pacifici said, "and to detect them all at once, in parallel, using the same chip."

To create the sensor, the researchers carved a slit about 100 nanometers wide and etched two 200 nanometer-wide grooves on either side of the slit. The slit captures incoming photons and confines them. The grooves, meanwhile, scatter the incoming photons, which interact with the free electrons bounding around on the sensor's metal surface. Those free electron-photon interactions create a surface plasmon polariton, a special wave with a wavelength that is narrower than a photon in free space. These surface plasmon waves move along the sensor's surface until they encounter the photons in the slit, much like two ocean waves coming from different directions and colliding with each other. This "interference" between the two waves determines maxima and minima in the light intensity transmitted through the slit. The presence of an analyte (the chemical being measured) on the sensor surface generates a change in the relative phase difference between the two surface plasmon waves, which in turns causes a change in light intensity, measured by the researchers in real time.

"The slit is acting as a mixer for the three beams -- the incident light and the surface plasmon waves," Pacifici said.

The engineers learned they could vary the phase shift for an interferometer by changing the distance between the grooves and the slit, meaning they could tune the interference generated by the waves. The researchers could tune the thousands of interferometers to establish baselines, which could then be used to accurately measure concentrations of glucose in water as low as 0.36 milligrams per deciliter.

"It could be possible to use these biochips to carry out the screening of multiple biomarkers for individual patients, all at once and in parallel, with unprecedented sensitivity," Pacifici said.

The engineers next plan to build sensors tailored for glucose and for other substances to further test the devices. "The proposed approach will enable very high throughput detection of environmentally and biologically relevant analytes in an extremely compact design. We can do it with a sensitivity that rivals modern technologies," Pacifici said.

Tayhas Palmore, professor of engineering, is a contributing author on the paper. Graduate students Jing Feng (engineering) and Vince Siu (biology), who designed the microfluidic channels and carried out the experiments, are listed as the first two authors on the paper. Other authors include Brown engineering graduate student Steve Rhieu and undergraduates Vihang Mehta, Alec Roelke.

Results are published in Nano Letters. The National Science Foundation and Brown (through a Richard B. Salomon Faculty Research Award) funded the research.

A Rice University research team makes graphene suitable for a variety of organic chemistry applications

The Air Force Office of Scientific Research (AFOSR), along with other funding agencies, helped a Rice University research team make graphene suitable for a variety of organic chemistry applicationsespecially the promise of advanced chemical sensors, nanoscale electronic circuits and metamaterials.

Ever since the University of Manchester's Andre Geim and Konstantin Novoselov received the 2010 Nobel Prize in Physics for their groundbreaking graphene experiments, there has been an explosion of graphene related discoveries; but graphene experimentation had been ongoing for decades and many ultimate graphene associated breakthroughs were already well under way in various labs when the Nobel committee acknowledged the significance of this new wonder material.

And one such laboratory was Dr. James Tour's at Rice, whose team found a way to attach various organic molecules to sheets of graphene, making it suitable for a range of new applications. Starting with graphene's two-dimensional atomic scale honeycomb lattice of carbon atoms, the Rice team built upon previous graphene community discoveries to transform graphene's one sheet structure into a superlattice.

While carbon is a key part in most organic chemical reactions, graphene poses a problem in that it plays an inert rolenot responding to organic chemical reactions. The Rice team solved this dilemma by treating graphene with hydrogen. This classic hydrogenation process restructured the graphene honeycomb lattice into a two-dimensional, semiconducting superlattice called graphane.

The hydrogenation process can then be tailored to make particular patterns in the superlattice to be followed by the attachment of mission specific molecules to where those hydrogen molecules are located. These mission specific molecular catalysts allow for the possibility of a wide variety of functionality. They can not only be used as the basis for creating graphene-based organic chemistry, but tailored for electronics and optics applications, as well as novel types of metamaterials for nanoengineering highly efficient thermoelectric devices and sensors for various chemicals or pathogens. The beauty of this process is the promise it holds for future devices with the ability to efficiently accomplish a wide variety of highly sophisticated functions in one small affordable device.

Dr. Charles Lee, the AFOSR program manager who funded this research, notes that graphene chemistry in general can enable smart materials for many special applications and that this latest effort in particular can contribute to future electronics applications and may be a way to arrive at faster and less energy consuming electronics.
