Experts from 80 countries cite time-limited opportunity, endorse comprehensive new eradication strategy

Hundreds of scientists, doctors and other experts from around the world launched the Scientific Declaration on Polio Eradication today, declaring that an end to the paralyzing disease is achievable and endorsing a comprehensive new strategy to secure a lasting polio-free world by 2018. The declaration's launch coincides with the 58th anniversary of the announcement of Jonas Salk's revolutionary vaccine.

The more than 400 signatories to the declaration urged governments, international organizations and civil society to do their part to seize the historic opportunity to end polio and protect the world's most vulnerable children and future generations from this debilitating but preventable disease. The declaration calls for full funding and implementation of the Polio Eradication and Endgame Strategic Plan 2013-2018, developed by the Global Polio Eradication Initiative (GPEI). With polio cases at an all-time low and the disease remaining endemic in just three countries, the GPEI estimates that ending the disease entirely by 2018 can be achieved for a cost of approximately $5.5 billion.

"We have the tools we need and a time-limited opening to defeat polio. The GPEI plan is the comprehensive roadmap that, if followed, will get us there," said Dr. Walter Orenstein, professor and associate director of the Emory Vaccine Center at Emory University and former director of the U.S. Centers for Disease Control and Prevention's National Immunization Program. Dr. Orenstein is one of the scientists spearheading the declaration and among the signatories who were on the frontlines of ending smallpox, the only human disease to be successfully eradicated.

The declaration housed online by Emory University at vaccines.emory.edu/poliodeclaration notes that polio vaccines have already protected hundreds of millions of children from the disease and eliminated one of the three types of wild poliovirus, proving that eradication is scientifically feasible. It calls on the international community to meet the goals in the GPEI plan for delivering polio vaccines to more children at risk, particularly in Afghanistan, Nigeria and Pakistan, where polio remains endemic and emergency action plans launched over the past year have resulted in significant improvements in vaccine coverage.

"Securing a lasting polio-free world goes hand in hand with strengthening routine immunization. We need all countries to prioritize investments in routine immunization," said Dr. Zulfiqar Bhutta, founding director of the Center of Excellence in Women and Child Health at Aga Khan University. Dr. Bhutta, one of the declaration's leaders, is a member of the Strategic Advisory Group of Experts (SAGE) on Immunization, a technical advisory body to the GPEI.

The declaration emphasizes that achieving polio eradication requires efforts interrelated with strengthening routine immunization, a new focus of the GPEI plan. As the last cases of polio are contained, high levels of routine immunization will be critical. At the same time, resources and learning from polio eradication efforts can be used to strengthen coverage of other life-saving vaccines, including for children who have never been reached with any health interventions before.

The scientists and experts signing the declaration called on the international community to take steps outlined in the GPEI plan to address challenges that have posed obstacles to polio eradication in the past, including improving immunization campaign quality to reach missed children and eliminating rare polio cases originated by the oral polio vaccine. While previous polio efforts have sought to interrupt wild virus transmission and then address vaccine-derived virus, the new GPEI plan addresses both simultaneously with a timetable to phase out use of oral polio vaccines and introduce inactivated polio vaccines. The declaration urges vaccine manufacturers to provide an affordable supply of the different vaccines required for eradication, and calls on scientists to continue researching new and better tools.

"As long as it exists anywhere in the world, polio threatens children everywhere," said Professor Helen Rees, executive director of the Wits Reproductive Health and HIV Institute at the University of the Witwatersrand in South Africa, who signed the declaration and chairs SAGE. "By pursuing in parallel all of the steps needed to reach eradication, including the introduction of inactivated vaccines, countries have a complete path to eliminate polio's threat." In November 2012, SAGE recommended the introduction of at least one dose of inactivated polio vaccine into all routine immunization programs prior to the phase-out of oral polio vaccines.

In light of recent attacks on health workers in some endemic countries, the declaration stresses the need to protect polio vaccination teams as they do their work. The GPEI plan includes a series of risk-mitigation strategies for insecure areas, including deepening engagement with community and religious leaders.

The scientists and experts signing the declaration hail from 80 countries and include Nobel laureates, vaccine and infectious disease experts, public health school deans, pediatricians and other health authorities. More than 40 leading universities and schools of public health and medicine are promoting the declaration on their websites, including Aga Khan University, the Harvard School of Public Health, the London School of Hygiene & Tropical Medicine, Al Azhar University (Egypt), University of Cape Town, Redeemer's University (Nigeria) and Christian Medical College Vellore (India).

The declaration notes that the world has a unique window of opportunity to eradicate polio. Only 223 new cases due to wild poliovirus were recorded in 2012, an historic low and a more than 99 percent decrease from the estimated 350,000 cases in 1988. Just 16 new cases have been reported so far in 2013 (as of 9 April). India, long-regarded as the most difficult place to eliminate polio, has not recorded a case in more than two years.

"Eradicating polio is no longer a question of technical or scientific feasibility. Rather, getting the most effective vaccines to children at risk requires stronger political and societal commitment," said Dr. David Heymann, head and senior fellow at the Chatham House Centre on Global Health Security and a signatory of the declaration. "Eliminating the last one percent of polio cases is an immense challenge, as is the eradication endgame after that. But by working together we can make history and leave the legacy of a polio-free world for future generations."

Google's Inactive Account Manager secures your digital existence when you no longer roam the Earth

If you're worried about what will happen to your mounds of digital data when you pass away, Google has just announced a feature for keeping said libraries secure. The outfit's Inactive Account Manager allows users to set time out periods of three, six, nine or 12 months for inactivity before deleting all of the stored files or having them handed over to a family member or "trusted contact." Those still left roaming the Earth can be granted access to Blogger, Drive, Gmail, Google+ and more without an application process, or they can simply be notified of the situation. Before any predetermined action is taken, the system will beam out a text and an email -- so if you're still around, you can halt matters from progressing further. Set up that digital will via the source links below and or by accessing the Google Account settings page.

Gaming Everything ? Blog Archive ? Batman: Arkham Origins ...

April 9th, 2013 Posted in 3DS, News, Screenshots, Vita Posted By: Valay

Update: Sorry guys! Images have been removed? I?m sure we?ll be seeing official content from Warner Bros. soon enough.

Batman: Arkham Origins isn?t the only new Batman game in development. Armature Studio is also working on Origins Blackgate, a new entry in the series for the 3DS and PlayStation Vita.

Game Informer has first information about Blackgate in this month?s issue. You can find images and details summarized below along with screenshots. There?s even more in Game Informer, so we highly advise that you take a look at this the publication?s May issue.

- Warner Bros. wanted to have a 2.5D-style Arkham game in the style of Metroidvania
- The company chose Armature because the studio was familiar with that style of game
- Takes place after the end of Origins
- Set on the isolated island at the Blackgate Penitentiary
- Prison uprising has occurred
- Intro level in Gotham
- Batman goes to Blackgate in order to put a stop to the riot
- 2D animatics with full voices tell the story
- Batman moves through a side-scrolling game world
- He?ll pick up near gear and take on enemies along the way
- Interconnected passages and prison secrets
- Not focused on leveling up abilities like the console games
- Instead, it stays true to the subgenre?s formula
- All of Batman?s improvements came through gear pick-ups and upgrades
- Team wanted to give players more of a sense of collection
- Mostly set along a 2D plane
- Takes full advantage of the visual three-dimensionality of the environments
- Explore, fight, and interact with the foreground abnd background
- Can grapple up to gargoyles on a background balcony while a crowd of armed inmates pass by
- Enemies will go after Batman from all angles
- Go to the foreground or background to tackle a designed foe
- Combat similar to the console Batman games
- Button taps to attack, counter, and use gear are in place
- Freeflow combat system
- Built from the ground up
- Batarang: stun enemies or hit distant objects
- Line launcher: cross wide gaps
- Explosive gel variation: shoot from a launcher onto spots around the screen
- This lets you get involved with entertaining takedowns such as dropping a chandelier on enemies from above
- More gadgets will also be in the game
- Has a version of the predator mode
- Game has a few more layers of feedback
- Ex: can see the sightlines of enemies
- This lets you know if enemies can see you or not
- Same kind of vantage points, floor grates, silent takedowns, glide kicks, weapon use, and breakable walls as in the console games
- Game is split into various sections
- Each can be accessed once you figure out a way inside
- No save rooms
- Modern checkpoint system
- Can manually save whenever you desire
- Can defeat the bosses in any ordder if you find out where you want to go
- ?We don?t want you to break the game, but if you can exploit it in a certain way that we haven?t thought of, that?s awesome. So it?s conceivable the players will have abilities that don?t necessarily jibe that great with the boss. We?ve taken some cues from other games where if you have a particular item against a boss, you?ll just rip them a new one, but we don?t tell you what that item is?
- Will have detective mode
- Tap a button and the screen fades into a digitized overlay with detailed info
- Green enemies: enemies haven?t seen you
- Red enemies: enemies are onto your location
- Move a reticle around the screen to focus Batman?s attention
- Can use this to uncover secrets
- Uncover clues and analyze dangerous situations in detective mode

Glass Explorer Edition To Ship Within The Next Month, Google Confirms

google glassToday during Google Venture’s “Glass Collective” event, Google told us that it hopes to get the Glass hardware into the hands of developers “within the next month.” The exact date for when Google plans to ship the first publicly available versions of Glass remains unknown, but Google has now confirmed to us that it is now very close to shipping the $1,500 devices to developers. Shipping Glass within the next month, of course, makes sense, given that Google will host its annual I/O developer conference in San Francisco from May 15 to 17. Glass will surely take center stage at this event, and if Google wants to get developers excited about the project and talk about (and launch) Glass’ Mirror API during I/O, it needs to get the hardware into the hands of developers soon. Last year, Google allowed I/O attendees to pre-register for Glass, but the company never really reached out to these developers since — except for sending them glass blocks with their wait-list number engraved on it. Google also recently allowed others to compete for the right to be among the first to buy Glass by posting their reasons for wanting Glass on Twitter and Google+. That project, which was going to bring about 8,000 additional early testers into the Glass community, was heavily criticized because it seemed Google (and the company it partnered with for this) just picked people randomly. Google later rescinded some of these invitations. Users who won the right to buy Glass have to pick it up in person in L.A., San Francisco or New York. It’s not clear if developers will have to do the same, but it would make sense for Google to allow developers to pick their kits up at I/O.

Student charged in college stabbings

CYPRESS, Texas (AP) ? A 20-year-old student went on a building-to-building stabbing attack at a Texas community college Tuesday, wounding at least 14 people ? many in the face and neck ? before being subdued and arrested, authorities said Tuesday.

The Harris County Sheriff's Office said in a statement that Dylan Quick had been planning the attack at the Lone Star College System's campus in Cypress for some time and had fantasies of stabbing people to death since he was in elementary school.

Quick, who was charged with three counts of aggravated assault, used a razor-type knife, and piece of the blade was found in at least one victim, the sheriff's office said. Broken blade pieces also were found in the area where the stabbing occurred, and the handle was discovered in a backpack that Quick was carrying when he was arrested.

Authorities were seen entering Quick's parents' home in a middle-class neighborhood of Houston on Tuesday night. No one answered the door or the phone at the red brick home, where two vehicles were parked in the driveway, including a Honda Accord with a license plate that said "DYLAN." It was not immediately known if Quick had an attorney.

The attack happened at 11:20 a.m. and sent at least 12 people to hospitals, while several others refused treatment at the scene, according to Cy-Fair Volunteer Fire Department spokesman Robert Rasa. Two people remained in critical condition Tuesday evening at Memorial Hermann Texas Trauma Institute, spokeswoman Alex Rodriguez said.

Diante Cotton, 20, said he was sitting in a cafeteria with some friends when a girl clutching her neck walked in, yelling: "He's stabbing people! He's stabbing people!"

Cotton said he could not see the girl's injuries, but when he and his friends went outside, they saw a half-dozen people with injuries to their faces and necks being loaded into ambulances and medical helicopters.

Harris County Sherriff Adrian Garcia said that when emergency calls came into the department, there were indications that "students or faculty were actively responding to work to subdue this individual."

"So we're proud of those folks, but we're glad no one else is injured any more severely than they are," Garcia said.

Michelle Alvarez told the Houston Chronicle she saw the attacker running toward other students and tried to back away. She said she didn't even feel it as he swiped at her.

"He came running and swinging at my neck, as I tried to get out of the way," she said.

The attack came three months after a different Lone Star campus was the site of a shooting in which two people were hurt. The suspected gunman in that incident is charged with aggravated assault.

Research enables fishermen to harvest lucrative shellfish on Georges Bank

Apr. 10, 2013 ? Combined research efforts by scientists involved in the Gulf of Maine Toxicity (GOMTOX) project, funded by NOAA's Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program, and administered by the National Centers for Coastal Ocean Science (NCCOS), have led to enhanced understanding of toxic algal blooms on Georges Bank. This new information, coupled with an at-sea and dockside testing protocol developed through collaboration between GOMTOX and U.S. Food and Drug Administration (FDA) investigators, has allowed fishermen to harvest ocean quahogs and surf clams in these offshore waters for the first time in more than two decades.

The shellfish industry estimates the Georges Bank fishery can produce up to 1 million bushels of surf clams and ocean quahogs a year, valued $10 -- 15 million annually. "There is a billion dollars' worth of shellfish product on Georges Bank that is property of the United States but that can't be harvested because of the threat of toxicity, and 99.9% of the time, it is good wholesome product," says Dave Wallace of North Atlantic Clam Association and a GOMTOX participant. "In an unusual and unique partnership, we worked with GOMTOX scientists, the FDA, and the states of Massachusetts, Rhode Island, New Jersey and Delaware and now that huge resource can go into commerce, which helps the entire country."

"We are extremely pleased that research funded by NOAA can provide such an economic boost to New England shellfisheries," says Robert Magnien, Director of NCCOS' Center for Sponsored Coastal Ocean Research. "It is a clear example of how research authorized by the Harmful Algal Bloom and Hypoxia Research and Control Act can protect both public health and local economies through collaborations between academic scientists, state and federal regulatory agencies, and the shellfish industry."

An elevated area of the sea floor between Cape Cod and Nova Scotia, Georges Bank is one of the best fishing grounds on Earth. But since 1990, it has been closed to harvesting of surf clams and ocean quahogs after harmful algal blooms (also referred to as "red tides") caused paralytic shellfish poisoning (PSP) that sickened fishermen. For decades scientists speculated the blooms on Georges Bank were fueled by coastal blooms in the Gulf of Maine.

More recent research by GOMTOX investigators, however, has shown that Georges Bank is home to a separate and distinct population of the toxic algae, which is described in a recently published paper by Woods Hole Oceanographic Institution (WHOI) scientist Dennis McGillicuddy and other members of the GOMTOX team.

It has been known for many years that the phytoplankton Alexandrium fundyense is the cause of the harmful algal blooms that occur to varying severity each spring and summer along the coastal Gulf of Maine, sometimes extending as far south as Cape Cod and the adjacent islands. The algae's seed populations or "cysts" germinate from seabeds starting in early spring and bloom at the sea surface, until all of the necessary nutrients in the water are consumed. As the nutrients run out, the cells form cysts and fall to the seafloor, as seed for the following spring. High concentrations of the toxic algae can cause closure of shellfish beds and cost the region many millions of dollars.

Precisely why the blooms vary in severity has been much more difficult to determine, and has involved extensive seasonal sampling of water and sediments, study of coastal currents, environmental and oceanographic conditions, availability of nutrients, and the development of a computer program to model all of the variables.

Researchers got the first signal that something very different was happening on Georges Bank during a research cruise to count Alexandrium cells in sea water samples in spring/summer 2007. "We devised our sampling strategy to look at the cells' transport pathways from coastal waters onto the Bank," says McGillicuddy. Throughout the coastal Gulf of Maine, the numbers were very low. But when the research team started sampling at Georges Bank, they found very high concentrations of Alexandrium in the water, despite the fact that the bloom had not really begun along the coast of Maine.

"I'll never forget the moment we hit a big patch of cells on Georges Bank," says Dave Townsend, a GOMTOX scientist from the University of Maine and co-author of the paper. "We extended our sampling to go all the way across Georges Bank and we were still hitting them. We had to turn around and completely reorganize our sampling strategy based on what we were seeing in the microscope."

For such a large bloom to occur, the researchers reasoned the number of cysts on Georges Bank must be similar to the quantities needed to initiate a bloom along the coast. Yet, their fall 2007 survey to map the cyst distribution in the seabed on the Bank found very few cysts -- quantities not likely to cause a large bloom along the coast.

In the three-year course of intensive study on Georges Bank since then, blooms have occurred every year, in concentrations that would typically lead to toxicities in coastal shellfish beds. Yet, a parallel effort by the fishing industry and federal testing labs to analyze shellfish samples from Georges Bank found the bivalves to be clean of toxins. So while toxins were produced at and near the surface, they were not delivered to the surf clams and ocean quahogs in the seabed in quantities sufficient to threaten human health.

The system on Georges Bank was indeed a riddle: Few cysts, yet large blooms; a large bloom, yet little to no toxicity in the shellfish. Applying the same detailed analyses to the offshore population of Alexandrium that they applied to coastal populations, the scientists discovered the optimum growing conditions for Alexandrium on Georges Bank were colder and saltier than those of their coastal relatives. Their analysis uncovered how the currents in the region can isolate Georges Bank to create colder and saltier conditions. If the conditions are favorable, the researchers say, Alexandrium populations can double every three days, and in a month's time, grow from concentrations of 10 cells per liter to 10,000.

Further setting the Georges Bank population apart was the finding by GOMTOX colleagues at University of Massachusetts, Dartmouth's School for Marine Science and Technology (SMAST), working in collaboration with the FDA, who determined that the toxin content of algae on Georges Bank was different than the coastal Gulf of Maine populations. "The toxins present in Alexandrium cells from Georges Bank were, on average, two times lower than those in the coastal Gulf of Maine," said Chrissy Petitpas, a doctoral student working in Professor Jefferson Turner's lab at SMAST.

Despite this new information and the knowledge that the clams have been shown to be safe for humans to eat at the present time, the fact remains that concentrations of the toxins in the clams on Georges Bank in 1989 and 1990 did reach dangerous levels. Scientists know that coastal shellfish populations are directly exposed to the toxins when the blooms make landfall, but they remain uncertain about the conduit for toxicity from the surface ocean to the deep shellfish beds on Georges Bank, located at about 50m depth.

But, thanks to an innovative screening protocol and regulatory structure developed collaboratively by the FDA, NOAA's National Marine Fisheries Service, the fishing industry, and testing labs approved by the National Shellfish Sanitation Program, a system is now in place to monitor, test, and verify that clams harvested from Georges Bank are safe. The clams are checked by fishermen at sea using the newly available test kit, and re-checked by regulators when the fishing vessels reach the dock. Combined with the weekly monitoring of shellfish beds along the coast during the bloom season to protect human health, these monitoring systems are extremely effective at keeping toxic shellfish off the market.

"Toxin levels in shellfish on Georges Bank have been very low over the last few years. We are confident that this new testing protocol will serve to protect public health should toxin levels rise again in the future," said Stacey DeGrasse, seafood research coordinator in the FDA's Office of Regulatory Science and a major participant in the development of the new offshore testing protocol. "We intend to continue to work closely with NOAA to ensure that the shellfish from this region are harvested safely."

"I've run over 2,500 samples from Georges Bank since mid-March, and all of them have been clean of toxin," says Darcie Couture, a former manager of the marine biotoxins program at the Maine Department of Marine Resources, who now operates the federally permitted testing lab. "We've been fortunate in finding a way that we can safely harvest that product out there."

"Although we can't predict when conditions on Georges Bank will favor a large bloom, our knowledge of the bloom dynamics was used in establishing a suitable management approach," says Don Anderson, a senior scientist at WHOI and the lead investigator on the GOMTOX project.

For the scientists, the work to understand the dynamics of the Georges Bank population continues. New DNA evidence uncovered by Woods Hole Center for Oceans and Human Health researchers Deana Erdner (University of Texas) and Mindy Richlen from Don Anderson's laboratory at WHOI, suggests the Georges Bank Alexandrium population is genetically distinct.

"We thought the Georges Bank population was just the little toe at the end of the coastal population, but it's not. It is separate, and it occupies a distinct niche from the rest of the Alexandrium in this region," says McGillicuddy. "This was a big surprise to us."

UK lawmakers pay tribute to Margaret Thatcher

LONDON (AP) ? British lawmakers remembered former Prime Minister Margaret Thatcher on Wednesday as a towering political figure who restored her country's confidence and pride ? but who alienated many voters, from coal miners to gay people, with her uncompromising policies.

Prime Minister David Cameron led praise for Thatcher during a special session of the House of Commons, recalled from its Easter break after the ex-leader's death Monday at the age of 87.

"Let this be her epitaph: That she made our country great again," Cameron told a packed room of lawmakers.

"She defined and she overcame the great challenges of her age and it is right that Parliament has been recalled to mark our respect," said Cameron, who heads the Conservative party that Thatcher once led.

The special sessions at the House of Commons are usual for former premiers, but are generally brief. More than seven hours was set aside for Thatcher, a reflection of her status as one of Britain's most iconic political figures ? and one whose legacy still sparks furious debate.

Legislators hailed a string of Thatcher's achievements, from privatization of cumbersome state-run industries to reclaiming the Falkland Islands after Argentina's 1982 invasion. They are once-controversial measures on which both government and opposition parties now broadly agree ? perhaps Thatcher's greatest accomplishment of all.

Amid the tributes, some lawmakers brought up the negative effects of her free-market economic policies ? unemployment, shuttered industries, frayed social bonds.

Ed Miliband, leader of the main opposition Labour Party, said Thatcher was "a unique and towering figure ... the prime minister who defined her age."

But he said that residents of mining communities were left "angry and abandoned" when she closed the country's coal pits after a bitter strike. And he said gay people "felt stigmatized" by Section 28, a 1980s government order banning what it called the promotion of homosexuality.

Labour Party lawmaker Glenda Jackson, an Oscar-winning actress in the 1970s, was met with howls from lawmakers when she launched a blistering attack on Thatcher's record.

"There was a heinous social, economic and spiritual damage wreaked upon this country," she told the House of Commons. "By far the most dramatic and heinous demonstration of Thatcherism was not only in London but across the whole country in metropolitan areas, where every single shop doorway, every single night, became the bedroom, the living room, the bathroom for the homeless."

Scottish and Irish nationalist legislators spoke of deep wounds that have not healed. Scottish National Party lawmaker Angus Robertson said that "we will never forget and never forgive" the poll tax ? an unpopular measure imposed on Scotland a year before the rest of the country.

Several left-wing legislators skipped the session altogether, including former housing minister John Healey, who said Thatcher's "legacy is too bitter to warrant this claim to national mourning."

Division over Thatcher's record has spilled over into debate about the public expense of her April 17 funeral at St. Paul's Cathedral, which will be attended by Queen Elizabeth II and dignitaries from around the world.

The only other funeral of a prime minister that the queen has attended was that of Britain's World War II leader, Winston Churchill, in 1965.

Thatcher's son, Mark, said the late premier "would be greatly honored as well as humbled" by the queen's presence at her funeral.

He added that his family had "quite simply been overwhelmed by messages of support" and condolence.

Thatcher's family is paying some of the cost of the funeral, which will see the former leader mourned with full military honors, but a portion will be paid by the state.

Taxpayers also will pick up the tab for lawmakers who have had to cut short vacations to attend Wednesday's session. They can claim expenses of up to 3,700 pounds ($5,750) for the journey.

Foreign Secretary William Hague said it was right to commemorate "a leader of historic proportions in our country's history."

He told the BBC: "I think we can afford to contribute to a funeral."

Thousands of people are expected to gather to see Thatcher's coffin taken from Parliament to the cathedral next week, part of the way by hearse and then on a horse-drawn gun carriage.

Hundreds of soldiers, sailors and air force personnel will line the route and form a guard of honor, and the coffin will be carried into the domed cathedral by members of units that fought in the 1982 Falklands War, Thatcher's high-risk military triumph. Military bands and artillery salutes will also form part of the carefully choreographed ceremony.

Police and security officials are planning for potential disruption from anti-Thatcher protesters ? who may stage celebrations during the funeral ? or attacks by Irish Republican Army dissidents.

Irish militants killed several Thatcher allies during her 1979-1990 premiership, and in 1984 set off a bomb in the Grand Hotel in Brighton during a Conservative Party conference. Thatcher escaped injury, but five people died.
