Telling tales can be a good thing: Personal stories help children develop emotional skills
Mar. 27, 2013 ? A new study finds that mothers tell better, more emotional stories about past experiences which help children develop their emotional skills.
The act of talking is not an area where ability is usually considered along gender lines. However, a new study published in Springer's journal Sex Roles has found subtle differences between the sexes in their story-relating ability and specifically the act of reminiscing. The research by Widaad Zaman from the University of Central Florida and her colleague Robyn Fivush from Emory University in Atlanta, Georgia, discusses how these gender differences in parents can affect children's emotional development.
Previous research in this area has concluded that the act of parents reminiscing with their children enables children to interpret experiences and weave together the past, present and future. There is also evidence that parents elaborate less when talking to sons than daughters.
The primary objective of Zaman's study was to compare the reminiscing styles of mothers and fathers with their pre-school daughters and sons. This included how they elaborated on the story and the extent to which their children engaged with the story while it was being told.
The researchers studied 42 families where the participating children were between four and five years old. Parents were asked to reminisce about four past emotional experiences of the child (happy, sad, a conflict with a peer and a conflict with a parent) and two past play interactions they experienced together. The parents took turns talking to the child on separate visits.
The researchers found that mothers elaborated more when reminiscing with their children than fathers. Contrary to previous research, however, Zaman's study found no differences in the extent to which either parent elaborated on a story depending on the sex of the child. Mothers tended to include more emotional terms in the story than fathers, which they then discussed and explained to the child. This increased maternal engagement has the effect of communicating to the child the importance of their own version, perspective and feelings about the experience.
The authors contend that through their increased interaction with the child, mothers are helping their children work through and talk about their experiences more than fathers, regardless of the type of experience. This may reflect the mother's efforts to try and help her child deal with difficult emotions, especially about negative experiences, all of which is related to better emotional well-being.
The authors conclude that "these results are intriguing, and a necessary first step to better understanding how parents socialize gender roles to girls and boys through narratives about the past, and how girls and boys may then incorporate these roles into their own narratives and their own lives."

Rihanna drops in on Chicago-area high school
BARRINGTON, Ill. (AP) ? Pop star Rihanna has dropped in on high school students in a northwestern Chicago suburb.
Barrington High School earned Friday's visit as a reward for winning the singer's "Shine Bright Like a Diamond" video contest.
The five-minute, student-produced video highlighted the school's volunteer and community service programs.
The Chicago Sun-Times reports (http://bit.ly/10wxpTC ) that the singer told students she admired their passion and volunteerism.
Rihanna showed up more than five hours late, but some in the crowd said she was worth the wait.
She also posed for photos before heading off to her Friday night concert at Chicago's United Center.
Barrington freshman Nisha Ali says "the fact that she came here and thanked us was a huge deal."

Apple executive talks about renewable energy and environmental goals
It's no secret that Apple strives to be as environmentally friendly as they can, and that includes renewable energy. At this time, about 75% of Apple's corporate headquarters are sustained on renewable energy sources. The Maiden, NC data center and their facilities in Cork, Ireland are some of the largest privately held installations for renewable energy in the world. Jim Dalrymple, from Loop Insight had a chance to speak with Apple executive Scott Brodrick on Apple's latest environmental impact report, which they issue every year, and where Apple is going when it comes to renewable energy and environmental goals.
Apple isn?t just looking at ways to save energy in its existing facilities, they are looking at starting off future facilities by taking advantage of renewable energy from the beginning.
?We are going to continue this strategy in other facilities in Oregon and Nevada,? said Broderick. ?Overall, 75% of the power to Apple?s corporate facilities worldwide are met with renewable energy.?
Apple's current energy strategy that they already have in place is the equivalent of taking 24,000 cars off the road, according to Brodrick. The entire article is an interesting read and a great insight into where Apple is going with renewable energy. Hit the link below to read it in its entirety.

Abramson: The lease agreement requires Children's to reopen NOAH
Posted by Charles Maldonado on Thu, Mar 21, 2013 at 6:38 PM
In an interview this afternoon, State Rep. Neil Abramson, D-New Orleans, told Gambit that he did not inform Children's Hospital of his plan to announce the reopening of New Orleans Adolescent Hospital (NOAH) before he appeared before the New Orleans City Council this morning. Children's disputed the announcement this afternoon in a statement.
But Abramson pointed out that the lease agreement for the NOAH property, signed by Children's, requires that the portion formerly housing the hospital "shall be administered, managed and operated so as to provide mental health care, including inpatient and outpatient services" consistent with the services provided before the hospital was closed by the Jindal Administration in 2009.
Representatives from Children's Hospital did not immediately return requests for comment.
?It specifically details how this property?s going to be handled, and part of that had to be was the piece about how the property?s going to be used," he said, adding that the law allowing for the lease also provided the same stipulations. ?Act 867 of state law particularly requires that the property be used for mental health services.?
Children's signed the agreement in January. Asked why he didn't announce it until today, Abramson the State Division of Administration was in possession of the contract, and he wasn't aware of it until earlier this month.
Act 867 gave Children's the right of first refusal to the lease, a provision Abramson wanted.
?I?m the one that made it happen that Children?s hospital got the exclusive right of first refusal," he said. ?There are others out there, but Children?s is the best partner.?
If Children's did not sign the lease by Feb. 1, 2013, the state would be allowed to offer the property to the highest bidder, which would also have to use the NOAH portion for mental health services, Abramson said. However, once it signed, the lease gives Children's two years to bring NOAH up to code. Children's signed just one week before the deadline. Asked if he thought the hospital signed merely to buy time to negotiate a sale or some other agreement, Abramson said he didn't know because he wasn't involved in negotiations.
He said that he is open to plans other than reopening NOAH, from Children's or another entity, but only if they involve the expansion of mental health services in New Orleans or the immediate area.
However, as of today, ?the only concrete proposal on the table was NOAH," he said.

NEW ORLEANS, LA. ? In an address to the New Orleans City Council today, State Representative Neil Abramson (D ? New Orleans) announced a long term lease agreement between Children?s Hospital and the State of Louisiana allowing Children?s to re-open the New Orleans Adolescent Hospital (NOAH) and provide mental health care for children and adolescents. Even though Abramson and his colleagues in the legislature funded NOAH, the Jindal administration closed NOAH in 2009 citing economic reasons and sent more than thirty patients to facilities as far away as the Northshore?s Southeast Louisiana Hospital. Last month, the Jindal administration agreed to allow a private company to operate the Northshore hospital and offer psychiatric care to patients. Abramson was an outspoken critic of sending our New Orleans children and adolescents far from home for mental health care. He advocated strongly for a partnership between NOAH and Children?s Hospital to find a solution to the challenge of protecting our youth and providing mental health services for children and adolescents.Abramson told the council, ?I have been through four years of detailed and tough negotiations to find a solution to the closing of NOAH. Louisiana and Children?s Hospital, with my legislative assistance and that of my colleagues, came together and reached an agreement. As part of that signed Agreement, Children?s Hospital is to re-open NOAH and provide out-patient services and in-patient care for our children and adolescents who are suffering from some form of mental health illness. I am very proud of the work done by the great doctors, administrators and staff at Children?s Hospital. It is an honor to represent the facility in my district. Like many, I treasure the expertise of the medical team at Children?s. I am here today to publicly thank Children?s Hospital for recognizing the need for mental health services for our youth and for caring enough to be a part of healing that will make our city stronger. I can?t imagine a better partner for our State than Children?s to address such a meaningful and monumental issue.? Pat Roy, former President of Friends of NOAH and a mental health community participant said, ?It is so uplifting to have Representative Abramson as an advocate for providing mental health care for our youth. It is critical to our community to supply mental health services to our children.?
The details of the negotiation and timeline for re-opening the NOAH facility were not released at the council meeting, but will be soon. Cecile Tebo, former head of the New Orleans Police Department's Mobile Crisis Unit and a mental health expert said, ?It is essential to diagnose and treat mental health issues at an early age. Representative Abramson has brought this issue to the forefront and it is great to have him as a progressive leader for this important issue.? Over 5 million American children now suffer some form of mental illness. Abramson represents District 98 in Uptown New Orleans.

FDA seeks to damp criticism over mobile health app proposals
By Toni Clarke
(Reuters) - The U.S. Food and Drug Administration said its plans for regulating certain healthcare apps used on smartphones and tablets will not impose undue burdens on developers or stifle the growing mobile health industry.
Christy Foreman, director of the FDA's device evaluation division, told a subcommittee of the House Energy and Commerce Committee on Thursday that the agency's goal is to foster technological innovation while protecting public safety.
The agency would not, as some had feared, regulate the sale or general consumer use of mobile devices, she said.
Foreman's comments came on the third day of hearings aimed at clarifying the types of health app to be regulated by the FDA and whether such apps would be subject to the 2.3 percent tax that some companies are required to pay on medical device sales under the Patient Protection and Affordable Care Act.
In July, 2011, the FDA published draft guidance in which it proposed regulating any mobile app deemed to be a medical device. It said it would not regulate personal wellness apps such as pedometers or heart-rate monitors, but would regulate an app that, for example, attaches to a mobile platform to collect and analyze heart and brain signals.
Foreman said that while the FDA is not responsible for taxation, a mobile app deemed to be a medical device would be subject to the medical device tax unless it is sold to consumers through retail stores, in which case it would be exempt.
Still, the FDA did not provide the detailed answers some had hoped for.
"The FDA says they are trying to limit the regulation to a small subset of apps but they have not clearly explained to the public what they consider a medical device," said Areta Kupchyk, partner at the law firm Nixon Peabody whose clients include mobile app developers.
Foreman said the FDA plans to release the final guidance by October.
According to a report published in March by research2guidance, a research and consulting firm, the market for mobile health services will likely reach $26 billion globally by 2017.
According to the report, there are 97,000 mobile health applications in major app stores, of which some 15 percent are primarily designed for the healthcare profession, including continued medical education, remote monitoring and healthcare management applications.
Charles Yim, founder and chief executive of Breathometer, an experimental, key fob-sized breathalyzer that plugs into a smartphone and calculates a breath alcohol content reading, is a serial technology developer who discovered his product will need to be cleared by the FDA.
"I wouldn't say it is preventing us from doing what we wanted to but it is an inhibitor," he said in an interview. "Apple has approved our app contingent on it getting FDA clearance, so that means we are solely reliant on government now."
Foreman said it takes the agency, on average, 67 days to clear a mobile app and that most will fall into the lower-risk categories of medical device that do not require onerous pre-market testing. The cost of an FDA application for a big company is $5,000, she said.
"For a small business," she said, "It's half that."

Life in the universe: Foundations of carbon-based life leave little room for error
Mar. 13, 2013 ? Life as we know it is based upon the elements of carbon and oxygen. Now a team of physicists, including one from North Carolina State University, is looking at the conditions necessary to the formation of those two elements in the universe. They've found that when it comes to supporting life, the universe leaves very little margin for error.
Both carbon and oxygen are produced when helium burns inside of giant red stars. Carbon-12, an essential element we're all made of, can only form when three alpha particles, or helium-4 nuclei, combine in a very specific way. The key to formation is an excited state of carbon-12 known as the Hoyle state, and it has a very specific energy -- measured at 379 keV (or 379,000 electron volts) above the energy of three alpha particles. Oxygen is produced by the combination of another alpha particle and carbon.
NC State physicist Dean Lee and German colleagues Evgeny Epelbaum, Hermann Krebs, Timo Laehde and Ulf-G. Meissner had previously confirmed the existence and structure of the Hoyle state with a numerical lattice that allowed the researchers to simulate how protons and neutrons interact. These protons and neutrons are made up of elementary particles called quarks. The light quark mass is one of the fundamental parameters of nature, and this mass affects particles' energies.
In new lattice calculations done at the Juelich Supercomputer Centre the physicists found that just a slight variation in the light quark mass will change the energy of the Hoyle state, and this in turn would affect the production of carbon and oxygen in such a way that life as we know it wouldn't exist.
"The Hoyle state of carbon is key," Lee says. "If the Hoyle state energy was at 479 keV or more above the three alpha particles, then the amount of carbon produced would be too low for carbon-based life.
"The same holds true for oxygen," he adds. "If the Hoyle state energy were instead within 279 keV of the three alphas, then there would be plenty of carbon. But the stars would burn their helium into carbon much earlier in their life cycle. As a consequence, the stars would not be hot enough to produce sufficient oxygen for life. In our lattice simulations, we find that more than a 2 or 3 percent change in the light quark mass would lead to problems with the abundance of either carbon or oxygen in the universe."
The researchers' findings appear in Physical Review Letters.
The work was funded by the U.S. Department of Energy; the Deutsche Forschungsgemeinschaft, Helmholtz-Gemeinschaft Deutscher Forschungszentren and Bundesministerium fuer Bildung und Forschung in Germany; European Union HadronPhysics3 Project and the European Research Council.

WASHINGTON (AP) ? President Barack Obama nominated a new ambassador to Libya on Wednesday, filling a post that has been vacant since Chris Stevens was killed in the Sept. 11 Benghazi attack and signaling the United States' commitment to the North African country as it undergoes a perilous transition from decades of dictatorship.
The announcement came as Secretary of State John Kerry was meeting Libyan Prime Minister Ali Zidan, and two days after the six-month anniversary of the storming of the U.S. diplomatic mission in the eastern Libyan city. No one has yet been captured for the attack, which has caused significant political headaches for Obama and his foreign policy team.
"The United States will continue to stand with Libya during this difficult time of transition," Kerry told reporters. "The Libyan people have begun to chart the course for their own future, and they're defining it. Obviously there are challenges ahead and we understand that, from building political consensus to strengthening the security and protecting human rights, and growing the Libyan economy."
Kerry thanked the Libyan government for its cooperation after the Benghazi attack and insisted that "those who killed Americans in Benghazi will be brought to justice." He promised Zidan that America would continue working for a stable Libya.
"We must not walk away from the difficult work that Chris Stevens and his cohorts were so dedicated to," Kerry said. Stevens was the first ambassador killed in the line of duty since the U.S. ambassador to Afghanistan in 1979.
To replace Stevens, the White House tapped Deborah K. Jones, a career diplomat who has served in Kuwait, United Arab Emirates and the now-shuttered U.S. Embassy in Syria. Jones, who currently works as a scholar at the Middle East Institute in Washington, also has spent time at embassies in Turkey and Ethiopia.
Jones will assume a difficult position heading the embassy in Libya's capital, Tripoli. The North African country has been beset by lawlessness, militant group rivalries and political instability since rebels, with the help of the U.S. and other governments, overthrew long-time dictator Moammar Gadhafi in 2011.
"She is a very capable and experienced diplomat," Kerry said of Jones. "I have no doubt that she will help to strengthen the partnership between us."
Zidan also met with Obama and his national security adviser Tom Donilon at the White House.
The president added his support Libya's democratic efforts and outlined areas the U.S. could help the government strengthen its institutions and improve the rule of law, according to a statement by Caitlin Hayden, spokeswoman for the National Security Council.
From Washington's perspective, the most pressing problem is insecurity.
Stevens and three other Americans were killed a half-year ago when a large group of men, possibly tied to Islamic extremist groups, assaulted the American outpost in Benghazi, and the help that arrived proved far too little and too late.
The militant group Ansar Al-Shariah is suspected of carrying out the attack, which the administration initially attributed to a protest over an American-made, anti-Islam video that spiraled out of control. Officials later retracted that account and called it a terror attack. But no one has been punished in Libya or elsewhere for involvement.
Zidan has been trying to reassert government control over Libya. Last month, he called on militias to evacuate buildings and headquarters and join government security forces, vowing that his government will take a hardline stand against any armed group that tries to hijack control of "Tripoli or Benghazi or any other city."
However, the Libyan government heavily depends on security provided by commanders of several powerful militias that the president has labeled "legitimate" forces. Militias in Libya often act with impunity, running their own prison cells, making arrests and taking confessions in total absence of state control and oversight.
The lawlessness also has allowed Gadhafi's once-vast stock of weapons to fall into the hands of extremists who've sparked a civil war in neighboring Mali. A France-led intervention has pushed back the Islamist militants after they seized half the country last year.
Speaking next to Kerry, Zidan thanked Obama and the U.S. for its key contribution in the effort to defeat Gadhafi. He said Libya would partner the U.S. in stabilizing his country and region.
"This relationship will be at the best level," Zidan, in his first to trip to Washington as prime minister, said through an interpreter.

North Korea abandons armistice: 4 key questions answered

A. The dictatorship has repeatedly violated the terms of the armistice by the use of lethal force against South Korean forces, notes Patrick Cronin, senior director of the Asia-Pacific Security Program at the Center for a New American Security. This happened most recently in 2010 when a North Korean submarine torpedoed the South Korean warship Cheonan, killing 46 South Korean military sailors.?
While a rhetorical threat to ignore the terms of the cease-fire is less consequential than the actual violations of the agreement in past years, notes Dr. Cronin, the bluster is still disturbing.
Pyongyang has repeatedly threatened to ignore the terms of the cease-fire, a move that is ?potentially quite dangerous? because it sets out the rules of interaction for the troops along the 38th parallel of the demilitarized zone, adds Victor Cha, senior adviser and the Korea Chair at the Center for Strategic and International Studies.
?If North Korea decides to drive trucks or bring heavier weapons into that area, that would be a violation of the armistice and potentially quite destabilizing because we would have to react to the introduction of heavy armaments,? he said. ?The point is that this is the most heavily militarized border in the world that is on a hair-trigger response.?

Missouri lawmakers vote to roll back income taxes
By Kevin Murphy
KANSAS CITY, Missouri (Reuters) - Missouri's Republican-controlled state Senate voted Tuesday to roll back income taxes, following the lead of neighboring Kansas and over the strong objections of Democratic Governor Jay Nixon.
By a 23-11 vote, the Senate sent the House a bill that would slightly reduce corporate income taxes over a five-year period, reduce the maximum tax rate on individuals and corporations and nearly double the $2,100 deduction for residents making less than $20,000 annually.
To offset the cuts, the bill calls for an increase in the state's sales and use tax from 4 to 4.5 percent, phased in over five years.
The move came amid heavy pressure from lawmakers in western Missouri concerned that recent income tax cuts engineered by Republican Governor Sam Brownback in Kansas would send companies and jobs over the state line.
"This bill represents a significant, broad-based tax cut for all Missourians who pay taxes, both residents and businesses," said state Senator Will Kraus, a suburban Kansas City Republican and sponsor of the bill.
In the prepared statement, Kraus said the bill reflects input from Democrats by giving tax breaks to small business and low-income residents.
In a letter to state senators on Monday, Nixon said cutting income taxes while raising sales taxes shifts the burden from the wealthy to those less fortunate.
"Everyday necessities, from clothing to Kleenex, would become more expensive," Nixon wrote.
"This shift would hit seniors and veterans living on fixed incomes especially hard."
Kraus said Nixon waited until the last minute of the two-month tax bill debate to make his views known. He described as "offensive" Nixon's suggestion that the bill harms veterans.
"Missourians deserve the truth, and the truth is that SB 26 represents an affordable tax cut that will save every taxpayer money," Kraus said.

Closest star system found in a century
Mar. 11, 2013 ? A pair of newly discovered stars is the third-closest star system to the Sun, according to a paper that will be published in Astrophysical Journal Letters. The duo is the closest star system discovered since 1916. The discovery was made by Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State University and a researcher in Penn State's Center for Exoplanets and Habitable Worlds.
Both stars in the new binary system are "brown dwarfs," which are stars that are too small in mass to ever become hot enough to ignite hydrogen fusion. As a result, they are very cool and dim, resembling a giant planet like Jupiter more than a bright star like the Sun.
"The distance to this brown dwarf pair is 6.5 light years -- so close that Earth's television transmissions from 2006 are now arriving there," Luhman said. "It will be an excellent hunting ground for planets because it is very close to Earth, which makes it a lot easier to see any planets orbiting either of the brown dwarfs." Since it is the third-closest star system, in the distant future it might be one of the first destinations for manned expeditions outside our solar system, Luhman said.
The star system is named "WISE J104915.57-531906" because it was discovered in a map of the entire sky obtained by the NASA-funded Wide-field Infrared Survey Explorer (WISE) satellite. It is only slightly farther away than the second-closest star, Barnard's star, which was discovered 6.0 light years from the Sun in 1916. The closest star system consists of Alpha Centauri, found to be a neighbor of the Sun in 1839 at 4.4 light years, and the fainter Proxima Centauri, discovered in 1917 at 4.2 light years.
Edward (Ned) Wright, the principal investigator for the WISE satellite, said "One major goal when proposing WISE was to find the closest stars to the Sun. WISE 1049-5319 is by far the closest star found to date using the WISE data, and the close-up views of this binary system we can get with big telescopes like Gemini and the future James Webb Space Telescope will tell us a lot about the low mass stars known as brown dwarfs." Wright is the David Saxon Presidential Chair in Physics and a professor of physics and astronomy at UCLA.
Astronomers have long speculated about the possible presence of a distant, dim object orbiting the Sun, which is sometimes called Nemesis. However, Luhman has concluded, "we can rule out that the new brown dwarf system is such an object because it is moving across the sky much too fast to be in orbit around the Sun."
To discover the new star system, Luhman studied the images of the sky that the WISE satellite had obtained during a 13-month period ending in 2011. During its mission, WISE observed each point in the sky 2 to 3 times. "In these time-lapse images, I was able to tell that this system was moving very quickly across the sky -- which was a big clue that it was probably very close to our solar system," Luhman said.
After noticing its rapid motion in the WISE images, Luhman went hunting for detections of the suspected nearby star in older sky surveys. He found that it indeed was detected in images spanning from 1978 to 1999 from the Digitized Sky Survey, the Two Micron All-Sky Survey, and the Deep Near Infrared Survey of the Southern Sky. "Based on how this star system was moving in the images from the WISE survey, I was able to extrapolate back in time to predict where it should have been located in the older surveys and, sure enough, it was there," Luhman said.
By combining the detections of the star system from the various surveys, Luhman was able to measure its distance via parallax, which is the apparent shift of a star in the sky due to Earth's orbit around the Sun. He then used the Gemini South telescope on Cerro Pach?n in Chile to obtain a spectrum of it, which demonstrated that it had a very cool temperature, and hence was a brown dwarf. "As an unexpected bonus, the sharp images from Gemini also revealed that the object actually was not just one but a pair of brown dwarfs orbiting each other," Luhman said.
"It was a lot of detective work," Luhman said. "There are billions of infrared points of light across the sky, and the mystery is which one -- if any of them -- could be a star that is very close to our solar system."

Bing Desktop now integrates better with Facebook, adds more customization options
It's been awhile since Microsoft made the Bing Desktop application compatible with more versions of Windows, but today the company's giving current (and potential) users more reasons to enjoy it. Most notably, Bing now lets social folks peek Facebook's News Feed and friends' photos from within the application, leaving out the need to launch a browser in a separate window. Furthermore, Microsoft also added the ability to search via the Windows Taskbar and some handy customization features, such as keyboard shortcuts and more wallpaper options with the help of Bing's renowned homepage images. Those in the US, UK, Australia, China, Canada, France, Germany, India and Japan can check out the revamped Bing Desktop now, though it's worth mentioning that the presence of a few of the new tidbits will vary depending on the country you're in and the Windows version you're running. Either way, you'll find the download at the source link below.

CAIRO (AP) ? Egyptian soccer fans rampaged through the heart of Cairo on Saturday, furious about the acquittal of seven police officers while death sentences against 21 alleged rioters were confirmed in a trial over a stadium melee that left 74 people dead.
The case of the Feb. 1, 2012 stadium riot in the city of Port Said at the northern tip of the Suez Canal has taken on political undertones not just because police faced allegations of negligence in the tragedy but also because the verdicts were announced at a time when Egypt is in the grip of the latest and most serious bout of political turmoil in the two years since Hosni Mubarak's ouster.
Saturday's verdicts also were handed down against the backdrop of an unprecedented wave of strikes by the nation's police force over demands for better working conditions and anger over what many believe are attempts by President Mohammed Morsi and his Muslim Brotherhood to take control of the police force.
Tensions over the riot ? which began when supporters of Port Said's Al-Masry club set upon fans of Cairo's Al-Ahly club after the final whistle of a league game that the home team won ? have fueled some of the deadliest street violence in months. Police guarding the stadium, meanwhile, faced allegations ranging from not searching people entering the stadium to failing to intervene to stop the bloodshed.
Shortly after the verdict was announced Saturday, angry fans of Cairo's Al-Ahly club who had gathered in the thousands outside the team's headquarters in central Cairo went on a rampage, torching a police club nearby and storming Egypt's soccer federation headquarters before setting it ablaze.
The twin fires sent plumes of thick black smoke billowing out over the Cairo skyline, prompting Defense Minister Abdel-Fattah el-Sissi to dispatch two army helicopters to extinguish the fires.
At least five people were injured in the protests over the verdict, a Health Ministry official told the MENA state news agency.
Some demonstrators in Port Said also burnt tires on the city's dock to prevent vessels from coming in and released speedboats into traffic lanes of the Suez Canal in attempts, foiled by the navy, to disrupt shipping in the vital waterway linking the Red Sea to the Mediterranean.
A spokesman for the Suez Canal Authority said shipping was not affected and 41 vessels transited the waterway on Saturday.
General unrest also continued elsewhere in the Egyptian capital, which has seen unrelenting demonstrations and clashes between security forces and an opposition that accuses Morsi of trying to monopolize power in the hands of his Islamist allies.
Two protesters also were killed and 19 injured in clashes elsewhere in the capital that appeared unrelated to the soccer violence, national ambulance service chief Mohammed Sultan said. The fighting occurred near two luxury hotels and the U.S. and British embassies.
The court's decision upheld the death sentences issued in late January against 21 people, most of them Port Said fans. The original verdict touched off violent riots in Port Said that left some 40 people dead, most shot by police.
On Saturday, the court announced its verdict for the other 52 defendants in the case, sentencing 45 of them to prison, including two senior police officers who got 15 years terms each. The two were charged with gross negligence and failure to stop the killings.
Twenty-eight people were acquitted, including seven police officials.
Defense lawyers claimed the case has been flawed from the start with prosecutors collecting evidence in an "unorthodox" fashion and overlooking key aspects of the tragedy such as the fact the floodlights were turned off during the attack on the Al-Ahly fans and the nearest exit gate was locked.
Many of the 74 victims died of suffocation or blows to the head.
Morsi's aides denounced Saturday's violence and sought to dismiss the notion of a country in chaos.
Ayman Ali, a senior presidential aide, called on the media not to provide a "political cover" to the violence sweeping the country and dismissed as exaggerated claims that the country's police force was in disarray.
Another presidential aide, Bakinam el-Sharqawy, lamented that the focus on protests and violence created an image of instability in Egypt that kept foreign investors away.
In anticipation of more violence, authorities beefed up security near the Interior Ministry, which is in charge of the police force, with riot police deploying in the streets around the complex in central Cairo.
The president of the international soccer governing body FIFA appealed for calm.
"I call on football fans in Egypt to remain peaceful. Violence is never a solution and is contrary to the spirit of sport," Sepp Blatter tweeted.
Earlier at the courthouse across town, Judge Sobhi Abdel-Maguid read out the verdict live on TV, sentencing five defendants to life in prison and nine others to 15 years in jail. Six defendants received 10-year jail terms, two more got five years and a single defendant received a 12-month sentence.
The court's decision on the nine Port Said security officers on trial was among the most highly anticipated ? and potentially explosive ? verdicts. In the end, the judges sentenced the city's former security chief, Maj. Gen. Essam Samak, and a colonel both to 15 years in prison, while the others were acquitted.
Al-Ahly's fans accuse the police of collusion in the killing of their fellow supporters, arguing that they had advance knowledge of plans by supporters of Port Said's Al-Masry to attack them. They also accuse them of standing by as the Al-Masry fans attacked the visiting Al-Ahly supporters.
The court rulings can be appealed before a higher court.
Many residents of Port Said say the trial is unjust and politicized, and soccer fans in the city have felt that authorities were biased in favor of Al-Ahly, Egypt's most powerful club.
In Port Said, a city that for weeks has been in open rebellion against Morsi, the Islamist leader, several hundred people, many of them relatives of the defendants, gathered outside the local security headquarters to vent their anger. They chanted slogans against Morsi's government and the verdicts. Police pulled out of the city on Friday after days of battling protesters in deadly clashes. The army has taken over security in the city, a move that was warmly welcomed by residents.
Some people in a cafe watching the verdict live on TV hit their heads in frustration, while others broke down and wept. Some said they can live with the verdict because an appeal leaves room for hope.
"There's still an appeal process. God willing, our rights will be restored," said Islam Ezzeddin, a local soccer fan. "We are not thugs. I hope to God when there's an appeal, that we feel we live in a country of law and justice."
However, the national railways chief, Hussein Zakaria, ordered trains headed to Port Said to terminate their services at Ismailiya, another Suez Canal city south of Port Said. He said the measure was taken out of fear for the safety of passengers.
Late on Saturday, activists in the city declared the start of a new general strike, with bands of protesters moving around the city pleading with business owners to shutter down.

Study: Even ancient mummies had clogged arteries
LONDON (AP) ? Even without modern-day temptations like fast food or cigarettes, people had clogged arteries some 4,000 years ago, according to the biggest-ever study of mummies searching for the condition.
Researchers say that suggests heart disease may be more a natural part of human aging rather than being directly tied to contemporary risk factors like smoking, eating fatty foods and not exercising.
CT scans of 137 mummies showed evidence of atherosclerosis, or hardened arteries, in one third of those examined, including those from ancient people believed to have healthy lifestyles. Atherosclerosis causes heart attacks and strokes. More than half of the mummies were from Egypt while the rest were from Peru, southwest America and the Aleutian islands in Alaska. The mummies were from about 3800 B.C. to 1900 A.D.
"Heart disease has been stalking mankind for over 4,000 years all over the globe," said Dr. Randall Thompson, a cardiologist at Saint Luke's Mid America Heart Institute in Kansas City and the paper's lead author.
The mummies with clogged arteries were older at the time of their death, around 43 versus 32 for those without the condition. In most cases, scientists couldn't say whether the heart disease killed them.
The study results were announced Sunday at a meeting of the American College of Cardiology in San Francisco and simultaneously published online in the journal Lancet.
Thompson said he was surprised to see hardened arteries even in people like the ancient Aleutians who were presumed to have a healthy lifestyle as hunter-gatherers.
"I think it's fair to say people should feel less guilty about getting heart disease in modern times," he said. "We may have oversold the idea that a healthy lifestyle can completely eliminate your risk."
Thompson said there could be unknown factors that contributed to the mummies' narrowed arteries. He said the Ancestral Puebloans who lived in underground caves in modern-day Colorado and Utah, used fire for heat and cooking, producing a lot of smoke.
"They were breathing in a lot of smoke and that could have had the same effect as cigarettes," he said.
Previous studies have found evidence of heart disease in Egyptian mummies, but the Lancet paper is the largest survey so far and the first to include mummies elsewhere in the world.
Dr. Frank Ruehli of the University of Zurich, who runs the Swiss Mummy Project, said it was clear atherosclerosis was notably present in antiquity and agreed there might be a genetic predisposition to the disease.
"Humans seem to have a particular vulnerability (to heart disease) and it will be interesting to see what genes are involved," he said. Ruehli was not connected to the study. "This is a piece in the puzzle that may tell us something important about the evolution of disease."
Other experts warned against reading too much into the mummy data.
Dr. Mike Knapton, associate medical director at the British Heart Foundation, said calcified arteries could also be caused by other ailments including endocrine disorders and that it was impossible to tell from the CT scans if the types of calcium deposits in the mummies were the kind that would have sparked a heart attack or stroke.
"It's a fascinating study but I'm not sure we can say atherosclerosis is an inevitable part of aging," he said, citing the numerous studies that have showed strong links between lifestyle factors and heart disease.
Researcher Thompson advised people to live as healthy a lifestyle as possible, noting that the risk of heart disease could be reduced with good eating habits, not smoking and exercising. "We don't have to end up like the mummies," he said.
