White House suggests Romney release tax forms

(AP) ? The White House is suggesting GOP presidential hopeful Mitt Romney should release his tax returns, saying it's "established tradition" for presidential candidates to do so.

Responding to a question about Romney's failure so far to release his returns, White House press secretary Jay Carney stopped short of directly calling on the former Massachusetts governor to make them public. But he noted that when Barack Obama was a presidential candidate he released multiple years of his returns.

Carney said making tax records public has been a standard practice for presidential candidates, though it's not a law.

On Monday night, Romney said that while he might be willing to release his tax returns, he wouldn't do so until tax filing time.

Carney made his comments Tuesday at a White House press briefing.

A first: Brain support cells from umbilical cord stem cells

ScienceDaily (Jan. 17, 2012) ? For the first time ever, stem cells from umbilical cords have been converted into other types of cells, which may eventually lead to new treatment options for spinal cord injuries and multiple sclerosis, among other nervous system diseases.

"This is the first time this has been done with non-embryonic stem cells," says James Hickman, a University of Central Florida bioengineer and leader of the research group, whose accomplishment is described in the Jan. 18 issue of the journal ACS Chemical Neuroscience.

"We're very excited about where this could lead because it overcomes many of the obstacles present with embryonic stem cells."

Stem cells from umbilical cords do not pose an ethical dilemma because the cells come from a source that would otherwise be discarded. Another major benefit is that umbilical cells generally have not been found to cause immune reactions, which would simplify their potential use in medical treatments.

The pharmaceutical company Geron, based in Menlo Park, Calif., developed a treatment for spinal cord repair based on embryonic stem cells, but it took the company 18 months to get approval from the FDA for human trials due in large part to the ethical and public concerns tied to human embryonic stem cell research. This and other problems recently led to the company shutting down its embryonic stem cell division, highlighting the need for other alternatives.

Sensitive Cells

The main challenge in working with stem cells is figuring out the chemical or other triggers that will convince them to convert into a desired cell type. When the new paper's lead author, Hedvika Davis, a postdoctoral researcher in Hickman's lab, set out to transform umbilical stem cells into oligodendrocytes-critical structural cells that insulate nerves in the brain and spinal cord-she looked for clues from past research.

Davis learned that other research groups had found components on oligodendrocytes that bind with the hormone norephinephrine, suggesting the cells normally interact with this chemical and that it might be one of the factors that stimulates their production. So, she decided this would be a good starting point.

In early tests, she found that norepinephrine, along with other stem cell growth promoters, caused the umbilical stem cells to convert, or differentiate, into oligodendrocytes. However, that conversion only went so far. The cells grew but then stopped short of reaching a level similar to what's found in the human nervous system.

Davis decided that, in addition to chemistry, the physical environment might be critical.

To more closely approximate the physical restrictions cells face in the body, Davis set up a more confined, three-dimensional environment, growing cells on top of a microscope slide, but with a glass slide above them. Only after making this change, and while still providing the norephinphrine and other chemicals, would the cells fully mature into oligodendrocytes.

"We realized that the stem cells are very sensitive to environmental conditions," Davis said.

Medical Potential

This growth of oligodendrocytes, while crucial, is only a first step to potential medical treatments. There are two main options the group hopes to pursue through further research. The first is that the cells could be injected into the body at the point of a spinal cord injury to promote repair.

Another intriguing possibility for the Hickman team's work relates to multiple sclerosis and similar conditions. "Multiple sclerosis is one of the holy grails for this kind of research," said Hickman, whose group is collaborating with Stephen Lambert at UCF's medical school, another of the paper's authors.

Oligodendrocytes produce myelin, which insulates nerve cells, making it possible for them to conduct the electrical signals that guide movement and other functions. Loss of myelin leads to multiple sclerosis and other related conditions such as diabetic neuropathy.

The injection of new, healthy oligodendrocytes might improve the condition of patients suffering from such diseases. The teams are also hoping to develop the techniques needed to grow oligodendrocytes in the lab to use as a model system both for better understanding the loss and restoration of myelin and for testing potential new treatments.

"We want to do both," Hickman said. "We want to use a model system to understand what's going on and also to look for possible therapies to repair some of the damage, and we think there is great potential in both directions."

Besides Hickman and Davis, the other authors on the paper were Xiufang Guo, Stephen Lambert, and Maria Stancescu, all from the University of Central Florida.

In gas lines, a look at Egypt's credibility gap (AP)

CAIRO ? Rumors about an impending hike in fuel prices sent Egyptians lining up at gas stations, spotlighting the latest crisis in Egypt's political transition at a time when the economy is reeling and anger is widespread over the pace of reform after former President Hosni Mubarak's ouster.

The latest challenge confronting Egypt's military rulers and the interim government came after government approval of a plan to cut energy subsidies for some industries was widely interpreted by the public as a move to cut subsidies for fuel on which millions of Egyptians depend.

Lines formed at gas stations, with some reportedly selling out of key grades of gasoline while others saying they had not received shipments of the fuel. As motorists stocked up, supplies were depleted and some stations turned customers away, further stoking the belief that not enough was being produced by the country.

Wael Ziada, head of Egypt research at Mideast investment bank EFG-Hermes said whatever the root cause of the crisis, it could "become a self-fulfilling prophecy" in which prices rise solely in response to the rumors, irrespective of whether there is any truth to them.

At a time when the government is trying to rein in spending and foreign reserves are bleeding away, Egypt spends about 40 percent of its budget on fuel and food subsidies. The support ensures at the pump and many basic staples in the groceries stores are cheap, a vital consideration for many in the country, where about 40 percent of the population of 85 million is near or below the poverty line.

Egyptian officials have been quick to deny that there is a problem with fuel production, blaming the shortage instead on unscrupulous traders out to make a quick profit.

The fuel crisis is a new, unwelcome headache for officials, already under pressure from a populace angry over the pace of reform and worried whether the military will make good on pledges to hand over power to a civilian authorities following presidential elections slated for June.

Petroleum Minister Abdullah Ghorab was quoted in Monday's edition of the daily Al-Masry Al-Youm as saying that that traders were essentially hoarding fuel to drive up prices.

Deputy Oil Minister Mahmoud Nazim denied that fuel prices would be increasing, reported the official MENA news agency. Nazim said the country was currently producing enough to meet daily domestic demand.

Official denials, however, have carried little resonance in post-Mubarak Egypt. The fuel crisis offers a window into the country's broader economic problems that have mushroomed since the authoritarian president was pushed from power in mid-February.

Mass protests have built up momentum over the past year, disrupting daily life, helping inject tremendous uncertainty into country's political transition and, in the end, undercutting efforts to attract tourists and foreign investors. Those two sectors are among Egypt's foreign currency mainstays. Net international reserves have fallen by 50 percent since December 2010, reaching $18 billion last month.

On Monday, a team from the International Monetary Fund began a mission to discuss with officials a potential $3.2 billion support package ? measures that could come with the kind of cost-cutting conditions that could stoke further undercurrents of unrest in a country where economic pain has only grown since the Jan. 25 uprising.

Officials turned down the IMF loan in June, arguing they did not want to saddle any new, incoming government with additional debt. But conditions have since deteriorated, with borrowing costs climbing while reserves dropped precipitously.

While the government has blamed the fuel issue on the market and unscrupulous traders, analysts worry that it may be a product of the government's cash crunch.

"If you don't have the cash to buy more gas, then you deal with a shortage and have to face the possibility of a black market," said Abdel-Moneim Said, an economic analyst with the Al-Ahram Strategic Center. "The government is trying to increase production, but local production is at capacity."

Compounding the problems of paying for fuel, the government faces other pressures. The country has also seen borrowing costs spiral as its sovereign credit rating has been repeatedly downgraded by the three main reporting agencies. Meanwhile, it is looking for cost-cuts in hopes of realizing its target budget deficit of 8.6 percent of gross domestic product in the current fiscal year.

The plan to cut energy subsidies that was approved by the government targeted some heavy industries, which have long benefited from low fuel costs.

Cutting those subsidies may have been a prudent step, analysts said, but the fact that it sparked a public panic that prices at the pump would also be going up reflects the government's problems in communicating policy objectives to a population that, after roughly three decades of Mubarak rule, distrusts anything coming from officials.

"This is another example of the lack of direction in terms of policy," said Said Hirsh, Mideast economist with Capital Economics in London. "If you put out notice that you're going to cut subsidies, you're going to get a run on stations."

"I would imagine this (fuel issue) to be related to the sense of confidence in decisions the government is making," said Hirsh.

Most officials agree subsidy cuts must happen in one form or another, especially since the gas subsidies benefit Egypt's rich as well. The issue is likely to come up during the government's discussions with the IMF over the $3.2 billion loan. Still, economists said the IMF probably won't demand drastic moves or impose stringent conditions, given the delicacy of the moment.

"It's a standard IMF approach to look at subsidies," said Hirsh. "They would press the government on how to deal with it. But it would be impossible to deal with it straight away. They would be sensitive to the societal pressures."

Dallas: We Never Wanted to Remake the Original (omg!)

After 21 years and one of the biggest TV cliff-hangers of all time, Dallas returns to TV this June on TNT. Just don't call the new series a reboot or a remake.

"I couldn't imagine making a remake. We've seen it. There were 357 episodes," Dallas executive producer Cynthia Cidre told reporters Saturday at TNT's winter TV previews. "It just seemed natural to catch up with Ewing family 20 years later."

When we return to Southfork, Bobby Ewing is happily re-married ? to Desperate Housewives' Brenda Strong! -- and his adopted son, Christopher (Jesse Metcalfe) is desperate to push the Ewing family into a new, more environmentally minded direction away from oil. However, J.R.'s son, John Ross (Josh Henderson), has very different ideas about the family business. In case you were worried that the new Dallas would lack conflict, John Ross' girlfriend Elena (The Fast and the Furious' Jordana Brewster) is also Christopher's ex-fianc?e. "[The script] honored all of the intricate elements of what Dallas was in the past, and basically, we've dropped back in 20 years later," executive producer Michael M. Robin said. "The storytelling elements are similar."

So how did producers lasso original stars Patrick Duffy, Linda Gray and Larry Hagman? "Work at 80. How many people do you know working at 80? And a job that they love with the people that they love," said Hagman, who told the crowd that his current cancer treatments are "going along very well."

And unlike other revamped series (? la Tori Spelling's blink-and-you-missed-it cameo on the new 90210), the returning original cast members aren't just back for nostalgia. "[The plan] was really to integrate them fully with the new cast. "It's not two separate storylines," Cidre said. "So far we've been in every episode, unless Cynthia and Mike have plans we don't know about," Duffy said, who said he's left his infamous shower-scene days behind him for the new kids. "The younger people have more stamina and they have a function in the show, but we're here."

(When asked about the chances of more returning characters, particularly Bobby Ewing's ex-wife Pam (Victoria Principal), producers sounded open to the idea should the series take off. "I don't know yet," Cidre said. "We create it one season at a time and hopefully we'll get a second season.")

Although Metcalfe, Henderson and the rest of the newbies won't have that same familiarity with audiences as the returning vets, they're not worried about winning over the fans. "Our characters are defined by who they are. Every bit of who Christopher is is part of Bobby, and the same with John Ross and J.R.," Metcalfe said. "We're the next generation that's carrying those timeless themes" of greed and love.

So how will producers make sure nothing overlaps with the series' original run? There's always someone watching. "From the beginning, I never wanted to violate anything that had actually happened," Cidre said. "Whenever we are making a choice in the present, someone is researching all 357 episodes. We want to honor the original show and the original conception."

So far it seems the team isn't having too hard of a time coming up with new material. "After 13 years, she gave me my first slap," Hagman teased about Gray. "You weren't supposed to hear that," she added, "but it was great!"

Will you watch the new Dallas?

Nations hunt for info on Italy cruise accident (AP)

PORTO SANTO STEFANO, Italy ? Language barriers, overwhelmed local authorities, squads of foreign diplomats with lists of awkward questions ? the international mix of passengers and crew aboard the stricken Costa Concordia cruise liner added to the complications Saturday for Italian officials handling the emergency.

Local authorities were fielding inquiries from dozens of nations worried about the 4,234 people who were aboard the ship when it ran aground and tipped over off the coast of Italy, including Italians, Germans, French people, Britons and Americans, and about 1,000 crew members from across the globe.

As international travel has grown easier, aid agencies and lawmakers alike have frequently warned of the potential for confusion in the wake of international emergencies, as sometimes competing nations or international organizations arrive at a disaster site.

In Italy, a host of countries sent diplomatic staff to the scene as three bodies were recovered from the sea off the tiny island of Giglio, close to the coast of Tuscany.

British ambassador Christopher Prentice said he had seen his counterparts from Germany and Spain at local hospitals, where diplomats were checking identities and tallying numbers of those injured.

Officials from the U.K. and Australia set up a joint base at Porto Santo Stefano middle school, which had been transformed into a temporary holding center for rescued passengers.

Though the school was a scene of chaos, as passengers tried to find buses to take them back to Rome or the coastal town of Savona ? where most had embarked ? and embassy officials cross-referenced ship logs and passenger lists, Prentice said nations were cooperating well.

"This is obviously a very serious and major incident, my impression at this stage is that the Italian authorities have responded excellently and our cooperation with them has been very good," Prentice said, as he offered advice to Britons at the school.

Other embassies sent lower-level officials to work with the ship operator Costa and local authorities, offering help to foreign passengers who didn't speak Italian and were struggling to understand the response to the accident or how to get home.

Consular officials wore bright green or orange emergency vests to identify themselves to their co-nationals, offering help in how to obtain emergency passports, since many non-Europeans had to turn them in to cruise officials upon boarding.

Prentice said that in a still unfolding crisis scenario, good coordination was key. "It is about cooperation, and things are being done here very calmly and sensibly, I've been impressed by the effort of the Italian authorities," he said.

As nations were still attempting to confirm the identities of passengers who had been rescued from the ship, rescuers focused on several dozen people still unaccounted for.

Monty Mathisen, of the New York-based publication Cruise Industry News, said Costa would be well prepared to handle the demands of countries searching for news of the passengers and crew.

"They are well set up to deal with those kind of issues," said Mathisen. "The cruise industry is one of most regulated industries."

Marcus Oxley, then disaster management director of the relief charity Tearfund told a committee of British lawmakers in 2006 of the nightmare confronting local authorities as organizations descend on an area requesting information, or offering help.

"In the white hot heat of an emergency these things are extraordinarily difficult to do," he said.

Some IVF patients don't follow doctor's orders (Reuters)

NEW YORK (Reuters Health) ? Doctors recommend women using fertility treatments cut back on certain activities to increase their chances of having children, but a new study suggests they're not listening.

Although recommendations are based on just a handful of studies in humans, doctors typically tell women to cut back or eliminate exercise, smoking, drinking and herbal supplement use during their in vitro fertilization (IVF) cycle. Some believe cutting back on those habits will increase the chance of a successful pregnancy.

"We said let's look at what women are actually doing. Are they doing what we've been recommending? The answer is no they are not," said Alice Domar, the study's lead author and executive director of the Domar Center for Mind and Body Health of Boston IVF in Waltham, Massachusetts.

Domar and her fellow researchers surveyed women going through an IVF cycle at Boston IVF between June 2009 and March 2010.

Overall, the group of 118 women seemed to be leading healthier lives at the time of their fertility treatments compared to the previous five years. However, the women's lifestyle choices during their cycle surprised Domar.

The researchers asked each woman to complete a daily survey while they were going through their cycle, which lasts about 28 days. The women stopped taking the survey when the cycle stopped.

Of the 111 women that completed the daily surveys, at least nine out of ten exercised once a week even though they were told to cut back.

In addition to the small amount of evidence that exercise can reduce the chance of a woman getting pregnant from IVF, the treatments increase the size of a woman's ovaries and can cause discomfort.

"Often, if they're not listening, it will get very uncomfortable if they're going for a jog," said Dr. Lynn Westphal from the Stanford School of Medicine, who was not involved with the new study.

About half of the women continued to drink alcohol during their cycle, and three out of four continued to drink caffeinated beverages.

Domar said she was particularly surprised that one out of every ten women took an herbal medication even though the clinic takes a strong stance against the supplements.

Westphal said she thinks most clinics suggest patients not use herbs.

"The problem with those situations is that we don't always know what's in these herbal preparations," said Westphal.

The survey's results are limited to a small group of women at one clinic, and the authors were not able to link the likelihood of a pregnancy to whether women were following recommendations. Domar said the results are surprising, however, because the treatments are expensive and the women want to get pregnant.

According to Domar, the treatments can cost between $12,000 and $18,000, but are covered by insurance in Massachusetts.

"I think the IVF population tends to be putting so much into this and they're typically so motivated," said Westphal. "You'd think that this population would be following the guidelines to a T."

Domar told Reuters Health that the center's guidelines are listed on its website, which the women have to log into to access their records. She said she is now encouraging the physicians to ask the women more questions.

"Clearly just having the information on the website isn't working," said Domar.

(AP) ? Prominent Afghan opposition leaders said Friday that they support possible U.S.-brokered peace negotiations with Taliban militants, but want to be part of any talks.

Members of a coalition representing Afghanistan's ethnic minorities spoke as they returned from a conference in Berlin, where they met with U.S. congressional leaders. Most of the delegation fought in the Northern Alliance against the Taliban government in the 1990s.

Minority support for any peace process is crucial because many former Northern Alliance figures wield power and influence, raising the possibility of civil strife if they don't approve of a deal with their longtime enemy.

The Taliban recently said they will open a political office in the Gulf state of Qatar and expressed interest in negotiations with the U.S., but it is so far unclear what other Afghan factions might be involved. The Taliban persist in referring to President Hamid Karzai's government as a puppet and stooge of foreign powers.

Prominent Tajik minority leader Ahmad Zia Masood said that he supports peace talks, but added that the government should be cautious of giving up too much to end the decade-long war. Most international troops are scheduled to withdraw by 2014, making achieving a negotiated peace an urgent priority.

"The achievements we have gained in the last 10 years, we shouldn't let go of them," Masood said.

Masood is a prominent leader of the Afghan National Front opposition coalition and the brother of slain Northern Alliance chief Ahmad Shah Masood, considered a national hero by anti-Taliban forces.

Ethnic Hazara leader Mohammad Muhaqiq said minority leaders should participate in any future talks.

"If the government is going to start a peace process, then we should also be in this process because we also represent part of the nation," he said. "If the peace process is not clear, then peace cannot be successful."

A spokesman for former Northern Alliance general Abdul Rashid Dostum said Friday that he also is in favor of peace talks despite earlier skeptical comments.

Dostum, a powerful Uzbek warlord accused of involvement in the deaths of 2,000 Taliban fighters shortly after the 2001 U.S.-led invasion, was quoted in Berlin as saying it would be "naive" to exclude the possibility that the Taliban are using negotiations to assuage the U.S. government while troops are being withdrawn, while planning to "resurge" after they are gone at the end of 2014.

The spokesman, Faizullah Zaki, told reporters Dostum's earlier comments were overblown. "The general doesn't have any objection to peace and he is on the side of the peace process."
