Conjoined twin girls successfully separated in 7-hour surgery









Surgeons and a 40-member medical team in Philadelphia have successfully completed the separation of 8-month-old twin girls who were joined at the lower chest and abdomen, according to the hospital where the procedure took place.

Children's Hospital of Philadelphia said the seven-hour operations were completed on Wednesday. It was the 21st time surgeons at the hospital had separated a set of conjoined twins. Other hospitals have also reported successful separations.

The twins, Allison June and Amelia Lee Tucker, of Adams, N.Y., shared a chest wall, diaphragm, pericardium and liver, according to a hospital statement.





Led by Dr. Holly L. Hedrick, pediatric general, thoracic and fetal surgeon, a multidisciplinary team of about 40 members, including physicians, nurses and other medical staff from general surgery, plastic and reconstructive surgery, cardiac surgery, anesthesiology, radiology, and neonatology, participated in the separation.

“Like all separations of conjoined twins, this was a very complex surgery, but it went very well and as expected,” said Hedrick, who led the team that worked on the patients. “Allison and Amelia are currently recovering in the Newborn/Infant Intensive Care Unit (N/IICU) and will be monitored closely by CHOP’s expert clinical teams for the duration of their recovery,” she stated.

“We expect that, with this complex surgery behind them, Allison and Amelia will receive the care, therapy and support to allow them to live full, healthy and independent lives,” Hedrick stated.

Conjoined twins occur once in every 50,000 to 60,000 births, and most are stillborn. About three-quarters of such twins are female and are joined at least partially in the chest, sharing organs. Chances of successful surgery and survival are greater if the twins have separate sets of organs, the hospital said.

The Tucker family has not commented. The hospital asked the media to respect the family’s privacy.

3D-Printed Rockets Help Propel NASA's Space Launch System











Parts for the rocket engines of NASA’s Space Launch System will be created using a method of 3D-printing known as selective laser melting.


The space agency is taking advantage of new technology to help improve safety and save money as it builds the SLS — a heavy-lift launch vehicle intended to facilitate long-duration deep space exploration, including trips to near-Earth asteroids and, ultimately, to Mars.


“It’s the latest in direct metal 3D printing — we call it additive manufacturing now,” says Ken Cooper, leader of the Advanced Manufacturing Team at the Marshall Centre. “It takes fine layers of metal powder and welds those together with a laser beam to fuse a three-dimensional object from a computer file.”

Although not all of the rocket parts can be generated using the current SLM process, it can be used to improve the overall safety of the system by creating the geometrically complex pieces which would normally require a lot of welding.


According to Andy Hardin, the integration hardware lead for the project, “since we’re not welding parts together, the parts are structurally stronger and more reliable, which creates an overall safer vehicle.”


The other benefit of using the 3D printing technology is its ability to reduce costs. Switching to SLM as a manufacturing method means that the rocket parts can be created faster and more cheaply, saving NASA millions of dollars.


After testing, the parts are expected to be used in the Space Launch System‘s test flight, scheduled for 2017.

On Twitter, pope to get different type of followers
















VATICAN CITY (Reuters) – Pope Benedict already has 1.2 billion “followers” in the standard sense of the word but he soon will have another type when he enters what for any 85 year old is the brave new world of Twitter.


Vatican officials say the pontiff, who is known not to love computers and still writes most of his speeches by hand, will have his own handle by the end of the year.













“It will be an officially verified channel,” said a Vatican official.


Primarily the tweets will come from the contents of his weekly general audience, Sunday blessings and homilies on major Church holidays. They will also include reaction to major world events, such as natural disasters.


The leader of the world’s 1.2 billion or so Roman Catholics will not, of course, write the tweets himself, but he will sign off on them before they are sent in his name.


But even divine intervention might not help squeeze the gist of a papal encyclical, which can run to more than 140 pages, into 140 characters.


Those tweets will probably be limited to a link to a url with the entire document.


The papal handle has not yet been disclosed but it is widely expected to be @BenedictusPPXVI, his name and title in Latin.


The pope has given a qualified blessing to social networking.


In a document issued last year, he said the possibilities of new media and social networks offered “a great opportunity”, but warned of the risks of depersonalisation, alienation, self-indulgence, and the dangers of having more virtual friends than real ones.


In 2009, a new Vatican website, www.pope2you.net, went live, offering an application called “The pope meets you on Facebook”, and another allowing the faithful to see the pontiff’s speeches and messages on their iPhones or iPods.


The Vatican famously got egg on its face in 2009 when it was forced to admit that, if it had surfed the web more, it might have known that a traditionalist bishop whose excommunication was lifted had for years been a Holocaust denier.

Malaria Vaccine Candidate Produces Disappointing Results in Clinical Trial


The latest clinical trial of the world’s leading malaria vaccine candidate produced disappointing results on Friday. The infants it was given to had only about a third fewer infections than a control group.


But researchers said they wanted to press on, assuming they keep getting financial support, because the number of children who die of malaria is so great that even an inefficient vaccine can save thousands of lives.


Three shots of the vaccine, known as RTS, S or Mosquirix and produced by GlaxoSmithKline, gave babies fewer than 12 weeks old 31 percent protection against detectable malaria and 37 percent protection against severe malaria, according to an announcement by the company at a vaccines conference in Cape Town.


Last year, in a trial in children up to 17 months old, the same vaccine gave 55 percent protection against detectable malaria and 47 percent against severe malaria.


The new trial “is less than we’d hoped for,” Moncef Slaoui, Glaxo’s chairman of research and development said in a telephone interview. “But if a million babies were vaccinated, we would prevent 260,000 cases of malaria a year. This is a disease that kills 655,000 babies a year — 31 percent of that is a very large number.”


The company, which has already spent more than $300 million on the vaccine, wants to keep forging ahead, he said, “but it is not just our decision.”


It also depends on the PATH Malaria Vaccine Initiative, which has put more than $200 million of its Bill and Melinda Gates Foundation financing into the vaccine, and on the World Health Organization, which has helped talk seven African countries into allowing the vaccine to be tested on their children.


The Gates Foundation declined to say how much money it was ultimately prepared to spend on an imperfect vaccine; this set of trials is set to go into 2014.


“The efficacy came back lower than we had hoped, but developing a vaccine against a parasite is a very hard thing to do,” Bill Gates said in a prepared statement. “The trial is continuing, and we look forward to getting more data to help determine whether and how to deploy this vaccine.”


All the families in the trial were given insecticide-impregnated mosquito nets and encouraged to use them; 86 percent did, so the vaccine worked despite other anti-malaria measures.


RTS, S contains a protein found on the parasite’s surface that provokes an immune reaction. It was first identified decades ago by two New York University scientists, Ruth and Victor Nussenzweig. The vaccine was developed by Glaxo in Belgium and initially tested on American volunteers by the Walter Reed Army Institute of Research. When the Gates Foundation began focusing on global health in the early part of this century, it was one of the first projects the foundation adopted. Different ways to make the vaccine more effective, including adding different boosters and giving more shots, are being experimented with. Other vaccines using different ways to provoke an immune reaction exist, but none are as far along in clinical trials.


Like an H.I.V. vaccine, one against malaria has proved an elusive goal. The parasite morphs several times, exhibiting different surface proteins as it goes from mosquito saliva into blood and then into and out of the liver. Also, even the best natural “vaccine” — catching the disease itself — is not very effective. While one bout of measles immunizes a child for life, it usually takes several bouts of malaria to confer even partial immunity. Pregnancy can cause women to stop being immune, and immunity can fade out if someone moves away from a malarial area — presumably because they no longer get “boosters” from repeated mosquito bites.

Gabrielle Giffords expected to attend Jared Loughner sentencing









Victims in the Tucson shooting rampage will get a chance to confront gunman Jared Lee Loughner, who will be  sentenced Thursday for killing six and wounding 13 people, including then-Rep. Gabrielle Giffords.

Giffords and her retired astronaut husband Mark Kelly are expected to be in court and make a statement before Loughner is sentenced by U.S. District Court Judge Larry A. Burns in Tucson. Other victims are also expected to appear.

Giffords was making a routine political appearance mid-morning on Jan. 8, 2011 at a supermarket parking lot in her Tucson district when Loughner opened fire, shooting her in the head. Passers-by rushed to help Giffords and wrestled Loughner to the ground. Before Loughner was subdued, he fired 31 more shots.





TIMELINE: Deadliest mass shootings in the U.S.

The nation then waited as doctors worked to save Giffords’ life in what has been described as a miraculous recovery. She then turned to her long-term and inspirational rehabilitation. Her first visit to Congress before stepping down from office led to a prolonged ovation from her colleagues.

The facts in the case were never in doubt. Loughner was the only suspect and the question focused on whether he would avoid the death penalty because of his mental health. After the shooting, Loughner was diagnosed with schizophrenia and underwent forcible psychotropic drug treatments.

Burns ruled that Loughner, now 24, was able to understand the charges against him, which eventually paved the way for a plea bargain designed to ensure that he would spend the rest of his life in prison without possibility of parole.

Three months ago, Loughner pleaded guilty to 19 federal charges. The agreement includes the dismissal of 30 other charges and a sentence of seven consecutive life terms, followed by 140 years in prison.

Giffords and some of the other victims said at the time that they welcomed the agreement because it meant that they could avoid a long and emotionally challenging court process that would have demanded they relive the events of that day.

Christina Pietz, the court-appointed psychologist who treated Loughner, had warned that although he was competent to plead guilty, he remained severely mentally ill and that he could deteriorate if forced to stand trial. Loughner, who has been in a prison medical facility in Springfield, Mo., for more than a year, is expected to serve his sentence in prison wards for the mentally ill.

Other victims are expected to make comments. Rep. Ron Barber, a former top aide to Giffords who replaced his boss in Congress, is expected to issue a statement. Barber is still awaiting word on whether he was re-elected to the seat on Tuesday.

Thursday’s proceedings end the federal case against Loughner. Pima County officials are still deciding whether to bring state charges.

Killed in the attack were:  John Roll, 63, presiding U.S. District Court judge for Arizona; Gabe Zimmerman, 30, one of Giffords' staffers; Christina-Taylor Green, a 9-year-old attending Giffords' event with an adult neighbor;  Dorwan Stoddard, 76; Dorothy Morris, 76; and Phyllis Schneck, 79, three retirees at the event.

In addition to Giffords and Barber, the wounded were: Mavy Stoddard (Dorwan's wife); George Morris (Dorothy's husband); Susan Hileman (Christina-Taylor's neighbor); Pam Simon, another Giffords staffer; and event attendees Bill Badger, Kenneth Dorushka, Eric Fuller, Randy Gardner, Mary Reed, James Tucker and Kenneth Veeder.

'SPDY,' High-Res Opera 12.10 Arrives








Opera has updated its flagship desktop web browser to version 12.10, which offers several speed improvements, new goodies for web developers and better integration with Apple’s latest Retina screen laptops.


To grab a copy of Opera 12.10 beta for Windows, Mac or Linux, head on over to the Opera download page.


Among Opera 12.10′s standout features is baked-in support for the new SPDY network standard, which offers faster, more secure connections to websites that support it, including big names like Gmail and Twitter.


Opera 12.10 now supports the latest Web Sockets implementation, which fixes the security flaws that previously forced Opera to remove Web Sockets support. Web Sockets are back on by default. Another web standards improvement in Opera 12.10 is support for more “unprefixed” CSS rules, including transitions, transforms, gradients, and animations, all of which will now work without the -o- prefix.


Web developers starting to play with the new CSS Flexible Box Layout Module syntax can now test layouts in Opera 12.10. Check out CSS guru Chris Coyer’s earlier rundown of what’s changed recently with Flexbox.


There’s good news for Mac users in this release — Opera 12.10 is the first to support Apple’s high-res display, making it well worth the update if you’ve got one of the new Retina MacBook Pros. Other Mac improvements include support for new features in OS X Mountain Lion, like the new Notification Center and the built-in content sharing through any social network accounts you’ve set up.


Windows 8 users will be happy to know that basic touch support now works in Windows 8. It’s nowhere near as nice as what you’ll find in IE 10 or Firefox, but it’s a start.

UK PM warns of witch-hunt against gays in pedophile scandal
















LONDON (Reuters) – British Prime Minister David Cameron warned on Thursday that speculation about the identity of an unidentified member of his ruling Conservative party accused of sexually abusing children could turn into a witch-hunt against gay people.


Cameron, who leads a troubled two-party coalition, ordered an investigation this week after a victim of child sexual abuse in Wales said a prominent Conservative political figure had abused him during the 1970s.













The claims, which follow the unmasking of late BBC star presenter Jimmy Savile as one of Britain’s most prolific sex offenders, have stoked concern that a powerful pedophile ring may have operated in Britain in the 1970s and 1980s.


“I have heard all sorts of names bandied around and what then tends to happen is of course that everyone then sits around and speculates about people, some of whom are alive, some of whom are dead,” Cameron said during an ITV television interview.


“It is very important that anyone who has got any information about any pedophile no matter how high up in the country go to the police,” he said.


Britain’s interior minister warned lawmakers this week that if they named suspected child abusers in parliament they risked jeopardizing future trials.


MPs benefit from “parliamentary privilege” – meaning they can speak inside parliament freely without fear of legal action on a host of legally sensitive issues that might otherwise attract lawsuits.


Reports of child abuse have provoked fevered speculation on the Internet about the identity of the Conservative figure from the era of Margaret Thatcher, prime minister from 1979 to 1990.


When the ITV interviewer passed Cameron a piece of paper with the names of people identified on the Internet as being alleged child abusers, Cameron said:


“There is a danger if we are not careful that this could turn into a sort of witch-hunt particularly against people who are gay.”


“I am worried about the sort of thing you are doing right now – giving me a list of names you have taken off the Internet,” Cameron said.


The BBC aired a program last week in which Steven Messham, one of hundreds of victims of sexual abuse at children’s care homes in Wales over two decades, said he had been sexually abused by a prominent Conservative political figure.


However, the BBC reporter said he could not name the figure because there was “simply not enough evidence to name names”.

Shares on Wall St. Slide Lower





Shares on Wall Street edged lower on Thursday as investors continued to adjust for upcoming negotiations over the so-called fiscal cliff, overshadowing a batch of positive economic data.


Investors worry that if no deal is reached in Congress over the fiscal cliff — some $600 billion in spending cuts and tax increases set to kick in early next year — it could derail the American economic recovery.


Data showed that the United States trade deficit narrowed in September as exports increased, suggesting that the economy expanded more than previously estimated in the third quarter.


Also on Thursday, the government reported than fewer Americans than expected filed new claims for unemployment benefits last week. The jobs data was distorted by the effects from Hurricane Sandy, though it was not clear if the storm increased or decreased claims.


“We’ve seen a big spike in the trend of the jobs market in the past few months,” said Adam Sarhan, chief executive of Sarhan Capital in New York. “We should react positively to this.”


In afternoon trading, Standard & Poor’s 500-stock index was down 0.3 percent, as was the Dow Jones industrial average. The Nasdaq composite was 0.5 percent lower.


On Wednesday, equities slumped more than 2 percent, as investor focus returned to Europe’s economic troubles and the looming tax hikes and budget cuts in the United States.


McDonald’s shares dropped 1.4 percent after the company reported a 1.8 percent drop in October sales at established restaurants around the world, its first monthly sales fall since March 2003.


Qualcomm reported quarterly revenue late Wednesday that beat expectations, sending shares up more than 6 percent.


Whole Foods Market reported earnings that met expectations, but its shares were down 4.9 percent.

Questions linger following Obama's reelection victory

President Obama celebrates his victory Wednesday, and plans a meeting with Republican presidential candidate Mitt Romney.









President Barack Obama has won re-election. The Republican Party faces a reckoning about its identity. In Florida, however, the election goes on.

The state whose dysfunctional voting methods traumatized the nation 12 years ago, is still up in the air.  The state was supposed to have been a major presidential battleground, but the morning after election day, it was still a question mark.

Instead of butterfly ballots and hanging chads, the problem appears to have been caused by a long ballot, high turnout and some mechanical failures.








Even the president, in his victory speech in Chicago, acknowledged the problem:

“I want to thank every American who participated in this election, whether you voted for the very first time or waited in line for a very long time--by the way, we have to fix that.”

PHOTOS: America goes to the polls

On Wednesday morning, all precincts in Florida had finished reporting, and the totals gave an edge of more than 46,000 votes to Obama, about half of one percent.  Even without Florida’s 29 electoral votes, Obama accrued far more than the 270 he needed to secure re-election. (Without Florida, the total was 303 electoral votes for the president to GOP challenger Mitt Romney’s 206.)

The worst of the problems occurred in Miami-Dade, the state's largest county. Long lines began before the polls opened Tuesday and never let up; when the election was called for Obama, people were still standing in line at dozens of precincts. The Miami Herald reported that the last Miami-Dade voter finished just after 1 a.m.

A number of counties had not yet counted their absentee ballots. In Miami-Dade, elections workers still had to count 20,000 absentees. In Pinellas County, which includes St. Petersburg, there were about 9,000 absentees yet to be counted. Elections officials said it would be Wednesday afternoon before the results would be final.

John Card, an attorney heading the Elections Protections monitoring effort in Miami-Dade on Tuesday, said voting actually went smoothly in much of the county. But in some precincts, he said, it was a "debacle."

Voters faced a ballot filled with complicated constitutional amendments and local issues. For some, it was 12 pages long. In some crowded precincts, scanners malfunctioned. In others, poll workers were confused about the state's new rules on address changes, Card said. Some voters were told they were ineligibleto vote, others may have been purged from rolls improperly.

LIVE: Presidential election results

"I do think they were a little overwhelmed in some places," he said. "A number of people got frustrated and left," said Card, whose organization is a coalition of advocacy groups. "The system played out in a way that denied them the right to vote."

The president’s victory may not have packed the same emotional punch as his historic 2008 win as the first African-American to win the presidency. But early Wednesday morning, as he stood on a Chicago stage to address the nation, he seemed to reconjure the conciliatory, high-minded politician the country first got to know four years ago.

That man—with the inspiring speeches and the ability to make Americans believe in their better angels--had sometimes disappeared under the fatigue, stress or just plain aversion to the brutal  campaign process.

The president attempted to set a peaceable tone for a country inflamed by hot partisan sentiment, stoked by the stunning amounts of money that had flowed unimpeded into the race.

Though his first term accomplishments, such as health care reform and a stimulus bill that most economists say helped stave off a second Great Depression, were accomplished with almost no Republican support, he vowed to be a better bi-partisan in his second term.

“I am looking forward to reaching out and working with leaders of both parties to meet the challenges we can only solve together:  reducing our deficit;  reforming our tax code; fixing our immigration system; freeing ourselves from foreign oil.”

PHOTOS: President Obama’s past

He also said he planned to meet with Romney “to talk about where we can work together to move this country forward.”

Before the president spoke, Romney, 65, the former Massachusetts governor, had conceded the election in a gracious but wistful speech before downcast supporters in Boston.

“I so wish that I’d been able to fulfill your hopes to consider as a course in a different direction,” Romney said in his brief speech, “but the nation chose another leader and so Ann and I join with you to earnestly pray for him and this great nation.” 

Meanwhile, in Washington, Republicans began to grapple with the party’s future. The party kept control of the House, but despite its hopes for much of the election cycle did not wrest control of the Senate from Democrats. Montana incumbent Jon Tester was declared the victor over Republican Denny Rehberg Wednesday morning, saving for Democrats one of Republicans’ biggest pick-up hopes.

With Romney vanquished, the party’s putative leaders are its top legislators, House Speaker John Boehner, Senate Minority Leader Mitch McConnell and House Majority Leader Eric Cantor.

But Romney’s running mate, Rep. Paul Ryan, often touted as the ideological leader of the party’s conservative wing, will have solidified his importance as the GOP grapples with its ideological future, as well as with the demographic changes that contributed to its failure to recapture the White House.

In a statement released after midnight Tuesday, Boehner congratulated the president, noted that the Republicans have maintained their majority in the House of Representatives, and cautioned the president.

“If there is a mandate,” said Boehner, “it is a mandate for both parties to find common ground and take steps together to help our economy grow and create jobs, which is critical to solving our debt.”
