Flu? Malaria? Disease forecasters look to the sky


NEW YORK (AP) — Only a 10 percent chance of showers today, but a 70 percent chance of flu next month.


That's the kind of forecasting health scientists are trying to move toward, as they increasingly include weather data in their attempts to predict disease outbreaks.


In one recent study, two scientists reported they could predict — more than seven weeks in advance — when flu season was going to peak in New York City. Theirs was just the latest in a growing wave of computer models that factor in rainfall, temperature or other weather conditions to forecast disease.


Health officials are excited by this kind of work and the idea that it could be used to fine-tune vaccination campaigns or other disease prevention efforts.


At the same time, experts note that outbreaks are influenced as much, or more, by human behavior and other factors as by the weather. Some argue weather-based outbreak predictions still have a long way to go. And when government health officials warned in early December that flu season seemed to be off to an early start, they said there was no evidence it was driven by the weather.


This disease-forecasting concept is not new: Scientists have been working on mathematical models to predict outbreaks for decades and have long factored in the weather. They have known, for example, that temperature and rainfall affect the breeding of mosquitoes that carry malaria, West Nile virus and other dangerous diseases.


Recent improvements in weather-tracking have helped, including satellite technology and more sophisticated computer data processing.


As a result, "in the last five years or so, there's been quite an improvement and acceleration" in weather-focused disease modeling, said Ira Longini, a University of Florida biostatistician who's worked on outbreak prediction projects.


Some models have been labeled successes.


In the United States, researchers at Johns Hopkins University and the University of New Mexico tried to predict outbreaks of hantavirus in the late 1990s. They used rain and snow data and other information to study patterns of plant growth that attract rodents. People catch the disease from the droppings of infected rodents.


"We predicted what would happen later that year," said Gregory Glass, a Johns Hopkins researcher who worked on the project.


More recently, in east Africa, satellites have been used to predict rainfall by measuring sea-surface temperatures and cloud density. That's been used to generate "risk maps" for Rift Valley fever — a virus that spreads from animals to people and in severe cases can cause blindness or death. Researchers have said the system in some cases has given two to six weeks advance warning.


Last year, other researchers using satellite data in east Africa said they found that a small change in average temperature was a warning sign cholera cases would double within four months.


"We are getting very close to developing a viable forecasting system" against cholera that can help health officials in African countries ramp up emergency vaccinations and other efforts, said a statement by one of the authors, Rita Reyburn of the International Vaccine Institute in Seoul, South Korea.


Some diseases are hard to forecast, such as West Nile virus. Last year, the U.S. suffered one of its worst years since the virus arrived in 1999. There were more than 2,600 serious illnesses and nearly 240 deaths.


Officials said the mild winter, early spring and very hot summer helped spur mosquito breeding and the spread of the virus. But the danger wasn't spread uniformly. In Texas, the Dallas area was particularly hard-hit, while other places, including some with similar weather patterns and the same type of mosquitoes, were not as affected.


"Why Dallas, and not areas with similar ecological conditions? We don't really know," said Roger Nasci of the Centers for Disease Control and Prevention. He is chief of the CDC branch that tracks insect-borne viruses.


Some think flu lends itself to outbreak forecasting — there's already a predictability to the annual winter flu season. But that's been tricky, too.


Seasonal flu reports come from doctors' offices, but those show the disease when it's already spreading. Some researchers have studied tweets on Twitter and searches on Google, but their work has offered a jump of only a week or two on traditional methods.


In the study of New York City flu cases published last month in the Proceedings of the National Academy of Sciences, the authors said they could forecast, by up to seven weeks, the peak of flu season.


They designed a model based on weather and flu data from past years, 2003-09. In part, their design was based on earlier studies that found flu virus spreads better when the air is dry and turns colder. They made calculations based on humidity readings and on Google Flu Trends, which tracks how many people are searching each day for information on flu-related topics (often because they're beginning to feel ill).


Using that model, they hope to try real-time predictions as early as next year, said Jeffrey Shaman of Columbia University, who led the work.


"It's certainly exciting," said Lyn Finelli, the CDC's flu surveillance chief. She said the CDC supports Shaman's work, but agency officials are eager to see follow-up studies showing the model can predict flu trends in places different from New York, like Miami.


Despite the optimism by some, Dr. Edward Ryan, a Harvard University professor of immunology and infectious diseases, is cautious about weather-based prediction models. "I'm not sure any of them are ready for prime time," he said.

Global share rally stalls as more U.S. budget battles loom

LONDON (Reuters) - A global share market rally petered out on Thursday as investors focused on U.S. political battles ahead over spending cuts, halting the gains that followed a deal to avoid sharp tax hikes.


The MSCI world equity index <.miwd00000pus> dipped from an 18-month high to be down 0.1 percent at 346.7 points while other riskier assets such as oil and the euro also eased.


The main share indexes in Germany <.gdaxi>, Britain <.ftse> and France <.fchi> were down 0.1 to 0.4 percent, having hit multi-month highs on Wednesday when relief swept the markets after U.S. lawmakers reached a deal to prevent a fiscal crunch.


But President Barack Obama and congressional Republicans face two more months of tough talks on spending cuts and an increase in the nation's debt limit as the hard-fought deal to avert the so called "fiscal cliff" covered only taxes and delayed decisions on expenditure until March 1.


"Of the three key issues - tax increases, spending cuts and the debt ceiling - policymakers have tackled just one," said Mouhammed Choukeir, chief investment officer at Kleinwort Benson.


"The fiscal cliff issue is unresolved. This is likely to increase market volatility, supporting safe-haven assets such as gold and some commodities," he said. "Paradoxically, as the U.S. debt and deficit issues continue to make investors jittery, the dollar can be expected to remain a safe-haven asset."


The dollar was up 0.3 percent <.dxy> against a basket of major currencies at a three-week high on Thursday, although it slipped 0.2 percent against the yen to 87.14.


The euro, which had touched an 8-1/2 month high against the dollar on Wednesday, was down was down 0.2 percent at $1.3162,.


"The reality is that budget talks will continue for the next two months and could get sour," said Jane Foley, senior currency strategist at Rabobank. "We see the dollar index reclaiming some ground."


The dollar's strength and profit-taking pushed oil prices lower, with Brent crude slipping 0.4 percent to $112 a barrel and U.S. crude futures down 45 cents to $92.67.


"After the initial excitement, reality sets in," said Victor Shum, oil consultant at IHS Purvin & Gertz. "There will be other negotiations and the (U.S.) deal is a compromise."


Gold was firm, holding near its highest level in two weeks hit on Wednesday in the wake of the initial U.S. fiscal deal. Spot gold was trading at $1,687.70 an ounce, up $1.35.


The precious metal ended 2012 with gains of around 7 percent - the 12th straight annual rise, and marking one of the longest bull runs for a commodity.


GROWTH OUTLOOK BRIGHTENS


Thursday's retreat across riskier asset markets might have been sharper but for data showing activity in China's services sector and at U.S. factories had expanded in December, brightening the outlook for global growth.


China's official purchasing managers' index (PMI) for the non-manufacturing sector rose to a four-month high in December, adding to signs of a revival in the world's second-largest economy.


Investors will now turn their attention to the December U.S. employment report on Friday. This is expected to show modest job growth of around 150,000 compared with 146,000 in November.

Myanmar says jets used against Kachin rebels


YANGON (Reuters) - Myanmar's military has used jets to attacks rebel fighters in northern Kachin state, the government said on Thursday, its first admission of an intensification of a conflict that has raised doubts about its reformist credentials.


Rebel sources have reported aerial bombings, shelling and even the use of chemical weapons since December 28 after the Kachin Independence Army (KIA) ignored an ultimatum to stop blocking an army supply route in the hilly, resource-rich state where more than 50,000 people have been displaced.


Official newspapers said that air support was used on December 30 to thwart KIA fighters who had occupied a hill and were attacking logistics units of the Tatmadaw, as Myanmar's military is known.


"The Tatmadaw troops cleared Point-771 hill and its surrounding areas where the KIA troops were attacking the Tatmadaw logistic troops," the New Light of Myanmar, a government mouthpiece, said. "The air cover was used in the attack."


U.N. Secretary-General Ban Ki-moon voiced concern on Wednesday over reports of helicopters and fighter jets being used in the state bordering China. The KIA said the attacks were intended to clear the path for an assault on its headquarters in Laisa.


Ban called on Myanmar's government to "desist from any action that could endanger the lives of civilians" and reiterated demands for humanitarian aid groups to be granted access, U.N. spokesman Martin Nesirky said in a statement.


President Thein Sein's quasi-civilian administration insists it wants a ceasefire and political dialogue. It says troops have acted only in self-defense and on Thursday denied having plans to seize the KIA's stronghold.


DOMINANT MILITARY


The escalation of fighting has raised doubts about the sincerity of the reformist ex-generals running the government and the extent of their power in a country the size of Britain and France plagued by decades of internal conflict.


Some analysts and diplomats say central government is either not fully committed to peace with the KIA or unable to assert control over the military, which still dominates politics and the economy despite formally ceding power in March 2011.


Colonel James Lum Dau, a Thai-based spokesman for the KIA's political wing, said Kachin officials on the ground had reported up to 300 people killed in air strikes.


"We are in a defensive position. Right now more people are suffering not only bombings, but shelling and spraying of chemical weapons with helicopter gunships and jets," he said. "Only god knows what to do. We are praying."


It is difficult for journalists to independently verify accounts from the two sides.


Fighting erupted in Kachin in June 2010, ending a 17-year truce, and has continued even as government negotiators have agreed ceasefires elsewhere with ethnic Shan, Chin, Mon and Karen militias after decades of fighting in border areas.


Mistrust runs deep between the military and the KIA, which was once backed by China, and multiple rounds of talks aimed at reaching a ceasefire have gone nowhere. Analysts say a history of bad blood and a battle for control of resources, including highly lucrative jade, could be stoking the unrest.


Zaw Htay, a senior official in Thein Sein's office, told Reuters no air strikes had taken place but K-8 trainer jets had provided cover fire to protect ground troops from rebel attacks. The military, he said, had no intention of seizing the KIA's headquarters.


"The president has said this and at the same time he has invited KIA leaders to come and talk with him in Naypyitaw, but they still haven't responded," Zaw Htay said.

Microsoft acquires start-up id8: source






SAN FRANCISCO (Reuters) – Microsoft Corp bought start-up id8 Group R2 Studios Inc as it looks to expand further in technology focused on the home and entertainment, a person familiar with the situation said on Wednesday.


id8 Group R2 Studios was started in 2011 by Silicon Valley entrepreneur and investor Blake Krikorian. It recently launched a Google Android application to allow users to control home heating and lighting systems from smartphones.






Krikorian’s Sling Media – which was sold to EchoStar Communications in 2007 – made the “Slingbox” for watching TV on computers.


Krikorian will join Microsoft with a small team, according to the Wall Street Journal, which reported the acquisition earlier on Wednesday. Microsoft also purchased some patents owned by the start-up related to controlling electronic devices, the newspaper added.


Krikorian and a Microsoft spokesman declined to comment.


Krikorian resigned from Amazon.com Inc’s board in late December after about a year and a half as a director at the company, the Internet’s largest retailer.

Hillary Clinton Recuperating at Home















01/03/2013 at 06:30 AM EST



The state of the Secretary of State has improved.

Hillary Rodham Clinton was discharged from New York Presbyterian/Columbia Hospital in Manhattan on Wednesday after checking in on Sunday for treatment of a blood clot in a vein in her head.

News photos showed the secretary, 65, leaving the facility with her husband, former President Bill Clinton, and daughter Chelsea. It is reported that she is now resting at the Clinton home in Chappaqua, N.Y.

"Her medical team advised her that she is making good progress on all fronts, and they are confident she will make a full recovery," Philippe Reines, a senior adviser to the secretary, said in a statement.

On Wednesday, Chelsea Clinton Tweeted, "Thank you to the doctors, nurses & staff at NewYork Presbyterian Hospital Columbia University Medical Center for taking great care of my Mom."

The New York Times quotes Dr. David J. Langer, a brain surgeon and associate professor at Hofstra North Shore-LIJ School of Medicine – and who is not involved in Clinton's treatment – as saying she will require close monitoring in the coming months to ensure she is on the proper doses of blood thinners and that the clot is not growing.

The blood clot was found in the space between her brain and skull behind the right ear during an exam related to a concussion Clinton sustained during a fall earlier last month in her Washington, D.C., home.

The series of health setbacks prevented Clinton from appearing at a Congress probe about the State Department's handling of the fatal attack on an American mission in Libya or attending President Obama's announcement that Senator John Kerry is his pick to serve as her successor when she soon steps down from her cabinet post.

Brain image study: Fructose may spur overeating


This is your brain on sugar — for real. Scientists have used imaging tests to show for the first time that fructose, a sugar that saturates the American diet, can trigger brain changes that may lead to overeating.


After drinking a fructose beverage, the brain doesn't register the feeling of being full as it does when simple glucose is consumed, researchers found.


It's a small study and does not prove that fructose or its relative, high-fructose corn syrup, can cause obesity, but experts say it adds evidence they may play a role. These sugars often are added to processed foods and beverages, and consumption has risen dramatically since the 1970s along with obesity. A third of U.S. children and teens and more than two-thirds of adults are obese or overweight.


All sugars are not equal — even though they contain the same amount of calories — because they are metabolized differently in the body. Table sugar is sucrose, which is half fructose, half glucose. High-fructose corn syrup is 55 percent fructose and 45 percent glucose. Some nutrition experts say this sweetener may pose special risks, but others and the industry reject that claim. And doctors say we eat too much sugar in all forms.


For the study, scientists used magnetic resonance imaging, or MRI, scans to track blood flow in the brain in 20 young, normal-weight people before and after they had drinks containing glucose or fructose in two sessions several weeks apart.


Scans showed that drinking glucose "turns off or suppresses the activity of areas of the brain that are critical for reward and desire for food," said one study leader, Yale University endocrinologist Dr. Robert Sherwin. With fructose, "we don't see those changes," he said. "As a result, the desire to eat continues — it isn't turned off."


What's convincing, said Dr. Jonathan Purnell, an endocrinologist at Oregon Health & Science University, is that the imaging results mirrored how hungry the people said they felt, as well as what earlier studies found in animals.


"It implies that fructose, at least with regards to promoting food intake and weight gain, is a bad actor compared to glucose," said Purnell. He wrote a commentary that appears with the federally funded study in Wednesday's Journal of the American Medical Association.


Researchers now are testing obese people to see if they react the same way to fructose and glucose as the normal-weight people in this study did.


What to do? Cook more at home and limit processed foods containing fructose and high-fructose corn syrup, Purnell suggested. "Try to avoid the sugar-sweetened beverages. It doesn't mean you can't ever have them," but control their size and how often they are consumed, he said.


A second study in the journal suggests that only severe obesity carries a high death risk — and that a few extra pounds might even provide a survival advantage. However, independent experts say the methods are too flawed to make those claims.


The study comes from a federal researcher who drew controversy in 2005 with a report that found thin and normal-weight people had a slightly higher risk of death than those who were overweight. Many experts criticized that work, saying the researcher — Katherine Flegal of the Centers for Disease Control and Prevention — painted a misleading picture by including smokers and people with health problems ranging from cancer to heart disease. Those people tend to weigh less and therefore make pudgy people look healthy by comparison.


Flegal's new analysis bolsters her original one, by assessing nearly 100 other studies covering almost 2.9 million people around the world. She again concludes that very obese people had the highest risk of death but that overweight people had a 6 percent lower mortality rate than thinner people. She also concludes that mildly obese people had a death risk similar to that of normal-weight people.


Critics again have focused on her methods. This time, she included people too thin to fit what some consider to be normal weight, which could have taken in people emaciated by cancer or other diseases, as well as smokers with elevated risks of heart disease and cancer.


"Some portion of those thin people are actually sick, and sick people tend to die sooner," said Donald Berry, a biostatistician at the University of Texas MD Anderson Cancer Center in Houston.


The problems created by the study's inclusion of smokers and people with pre-existing illness "cannot be ignored," said Susan Gapstur, vice president of epidemiology for the American Cancer Society.


A third critic, Dr. Walter Willett of the Harvard School of Public Health, was blunter: "This is an even greater pile of rubbish" than the 2005 study, he said. Willett and others have done research since the 2005 study that found higher death risks from being overweight or obese.


Flegal defended her work. She noted that she used standard categories for weight classes. She said statistical adjustments were made for smokers, who were included to give a more real-world sample. She also said study participants were not in hospitals or hospices, making it unlikely that large numbers of sick people skewed the results.


"We still have to learn about obesity, including how best to measure it," Flegal's boss, CDC Director Dr. Thomas Frieden, said in a written statement. "However, it's clear that being obese is not healthy - it increases the risk of diabetes, heart disease, cancer, and many other health problems. Small, sustainable increases in physical activity and improvements in nutrition can lead to significant health improvements."

Stock futures surge on fiscal deal

During an oddly jokey statement at the White House as the fiscal deadline bore down Monday afternoon, President Obama said, "I'm going to be president for the next four years. I hope." He was warning Republicans that, yes, they'd have to deal with him for a while. But it was, to be sure, a strange moment. Could he actually have been joking about assassination? About impeachment? The apocalypse? Or has everyone just had enough of these negotiations?

Syrian rebels attack military airport in northwest


BEIRUT (Reuters) - Syrian rebels, some from Islamist units, fired machineguns and mortars at helicopters grounded at a northern military air base near the main Aleppo-Damascus highway on Wednesday, a monitoring group said.


The al Qaeda-linked al-Nusra Front, Ahrar al-Sham Brigade and other units operating in Syria's northwestern province of Idlib were attacking the Afis military airport near Taftanaz, the pro-opposition Syrian Observatory for Human Rights said.


There was no immediate account of the fighting around the air base from Syrian state media.


Insurgents trying to topple President Bashar al-Assad see his air power as their main threat. They hold swathes of eastern and northern provinces, as well as a crescent of suburbs around the capital, Damascus, but have been unable to protect rebel-held territory from relentless attack by helicopters and jets.


In recent months, rebel units have besieged several military installations, especially along Syria's main north-south artery from Aleppo, its most populous city, to Damascus.


The Observatory's director, Rami Abdelrahman, said Wednesday's attack was the latest of several attempts to capture the base. A satellite image of the airport shows more than 40 helicopter landing pads, a runway and aircraft hangars.


An estimated 45,000 people have been killed in the Syrian conflict, which began in March 2011 with peaceful protests against four decades of Assad family rule but turned into an armed revolt after months of government repression.


In Damascus, Assad's forces fired artillery and mortars at the eastern districts of Douma, Harasta, Irbin and Zamlaka, where rebels have a foothold, activists living there said.


Syria's civil war is the longest and deadliest conflict to emerge from uprisings that began sweeping the Arab world in 2011 and has developed a significant sectarian element.


Rebels, mostly from the Sunni Muslim majority, confront Assad's army and security forces, dominated by his Shi'ite-derived Alawite sect, which, along with some other minorities, fears revenge if he falls.


U.N.-led diplomatic peace efforts have stumbled. Western and many Sunni Arab states demand Assad's immediate removal, an idea resisted by Russia, China and Syria's Shi'ite ally Iran.


The rebels say they will not negotiate unless Assad, who has vowed to fight to the death, leaves power.


More than 110 people, including at least 31 of Assad's soldiers and militiamen, were killed in Syria on the first day of 2013, according to the Observatory, which tracks the conflict from Britain using a network of contacts inside the country.
