Google and Twitter Help Track Influenza Outbreaks


This flu season could be the longest and worst in years. So far 18 children have died from flu-related symptoms, and 2,257 people have been hospitalized.

Yesterday Boston Mayor Thomas Menino declared a citywide public health emergency, with roughly 700 confirmed flu cases—ten times the number the city saw last year.

"It arrived five weeks early, and it's shaping up to be a pretty bad flu season," said Lyn Finelli, who heads the Influenza Outbreak Response Team at the Centers for Disease Control and Prevention (CDC).

Boston isn't alone. According to the CDC, 41 states have reported widespread influenza activity, and in the last week of 2012, 5.6 percent of doctor's office visits across the country were for influenza-like illnesses. The severity likely stems from this year's predominant virus: H3N2, a strain known to severely affect children and the elderly. Finelli notes that the 2003-2004 flu season, also dominated by H3N2, produced similar numbers. (See "Are You Prepped? The Influenza Roundup.")

In tracking the flu, physicians and public health officials have a host of new surveillance tools at their disposal thanks to crowdsourcing and social media. Such tools let them get a sense of the flu's reach in real time rather than wait weeks for doctor's offices and state health departments to report in.

Pulling data from online sources "is no different than getting information on over-the-counter medication or thermometer purchases [to track against an outbreak]," said Philip Polgreen, an epidemiologist at the University of Iowa.

The most successful of these endeavors, Google Flu Trends, analyzes flu-related Internet search terms like "flu symptoms" or "flu medication" to estimate flu activity in different areas. It tracks flu outbreaks globally.

Another tool, HealthMap, which is sponsored by Boston Children's Hospital, mines online news reports to track outbreaks in real time. Sickweather draws from posts on Twitter and Facebook that mention the flu for its data.

People can be flu-hunters themselves with Flu Near You, a project that asks people to report their symptoms once a week. So far more than 38,000 people have signed up for this crowdsourced virus tracker. And of course, there's an app for that.

Both Finelli, a Flu Near You user, and Polgreen find the new tools exciting but agree that they have limits. "It's not as if we can replace traditional surveillance. It's really just a supplement, but it's timely," said Polgreen.

When people have timely warning that there's flu in the community, they can get vaccinated, and hospitals can plan ahead. According to a 2012 study in Clinical Infectious Diseases, Google Flu Trends has shown promise predicting emergency room flu traffic. Some researchers are even using a combination of the web database and weather data to predict when outbreaks will peak.

As for the current flu season, it's still impossible to predict week-to-week peaks and troughs. "We expect that it will last a few more weeks, but we can never tell how bad it's going to get," said Finelli.

Hospitals are already taking precautionary measures. One Pennsylvania hospital erected a separate emergency room tent for additional flu patients. This week, several Illinois hospitals went on "bypass," alerting local first responders that they're at capacity—due to an uptick in both flu and non-flu cases—so that patients will be taken to alternative facilities, if possible.

In the meantime, the CDC advises vaccination, first and foremost. On the bright side, the flu vaccine being used this year is a good match for the H3N2 strain. Though Finelli cautions, "Sometimes drifted strains pop up toward the end of the season."

It looks like there won't be shortages of seasonal flu vaccine like there have been in past years. HealthMap sports a Flu Vaccine Finder to make it a snap to find a dose nearby. And if the flu-shot line at the neighborhood pharmacy seems overwhelming, more health departments and clinics are offering drive-through options.

Judge: Holmes Can Face Trial for Aurora Shooting


Jan 10, 2013 8:45pm

In a ruling that comes as little surprise, the judge overseeing the Aurora, Colo., theater massacre has ordered that there is enough evidence against James Holmes to proceed to a trial.


In an order posted late Thursday, Judge William Sylvester wrote that “the People have carried their burden of proof and have established that there is probable cause to believe that Defendant committed the crimes charged.”


The ruling came after a three-day preliminary hearing this week that revealed new details about how Holmes allegedly planned for and carried out the movie theater shooting, including how investigators say he amassed an arsenal of guns and ammunition, how he booby-trapped his apartment to explode, and his bizarre behavior after his arrest.

Holmes is charged with 166 counts, including murder, attempted murder and other charges related to the July 20 shooting that left 12 people dead and 58 wounded by gunfire. An additional 12 people suffered non-gunshot injuries.


One of the next legal steps is an arraignment, at which Holmes will enter a plea. The arraignment was originally expected to take place Friday morning.


Judge Sylvester indicated through a court spokesman that he would allow television and still cameras into the courtroom, providing the outside world the first images of Holmes since a July 23 hearing. Plans for cameras in court, however, were put on hold Thursday afternoon.


“The defense has notified the district attorney that it is not prepared to proceed to arraignment in this case by Friday,” wrote public defenders Daniel King, Tamara Brady and Kristen Nelson Thursday afternoon in a document objecting to cameras in court.


A hearing in the case will still take place Friday morning. In his order, Judge Sylvester said it should technically be considered an arraignment, but noted the defense has requested a continuance.  Legal experts expect the judge will grant the continuance, delaying the arraignment and keeping cameras out of court for now.


Sylvester also ordered that Holmes be held without bail.


Holmes’ attorneys have said in court that the former University of Colorado neuroscience student is mentally ill. The district attorney overseeing the case has not yet announced whether Holmes, now 25, can face the death penalty.

Hints of new dark force seen in galactic smash-ups









































Colliding clusters of galaxies may hold clues to a mysterious dark force at work in the universe. This force would act only on invisible dark matter, the enigmatic stuff that makes up 86 per cent of the mass in the universe.












Dark matter famously refuses to interact with ordinary matter except via gravity, so theorists had assumed that its particles would be just as aloof with each other. But new observations suggest that dark matter interacts significantly with itself, while leaving regular matter out of the conversation.












"There could be a whole class of dark particles that don't interact with normal matter but do interact with themselves," says James Bullock of the University of California, Irvine. "Dark matter could be doing all sorts of interesting things, and we'd never know."











Some of the best evidence for dark matter's existence came from the Bullet clusterMovie Camera, a smash-up in which a small galaxy cluster plunged through a larger one about 100 million years ago. Separated by hundreds of light years, the individual galaxies sailed right past each other, and the two clusters parted ways. But intergalactic gas collided and pooled on the trailing ends of each cluster.













Mass maps of the Bullet cluster showed that dark matter stayed in line with the galaxies instead of pooling with the gas, proving that it can separate from ordinary matter. This also hinted that dark matter wasn't interacting with itself, and was affected by gravity alone.











Musket shot













Last year William Dawson of the University of California, Davis and colleagues found an older set of clusters seen about 700 million years after their collision. Nicknamed the Musket Ball cluster, this smash-up told a different tale. When Dawson's team analysed the concentration of matter in the Musket Ball, they found that galaxies are separated from dark matter by about 19,000 light years.












"The galaxies outrun the dark matter. That's what creates the offset," Dawson said. "This is fitting that picture of self-interacting dark matter." If dark matter particles do interact, perhaps via a dark force, they would slow down like the gas.












This new picture could solve some outstanding mysteries in cosmology, Dawson said this week during a meeting of the American Astronomical Society in Long Beach, California. Non-interacting dark matter should sink to the cores of star clusters and dwarf galaxies, but observations show that it is more evenly distributed. If it interacts with itself, it could puff up and spread outward like a gas.












So why doesn't the Bullet cluster show the same separation between dark matter and galaxies? Dawson thinks it's a question of age – dark matter in the younger Bullet simply hasn't had time to separate.











New window












The idea complements a previous study that saw evidence for dark forces at work in the Bullet cluster. In 2007 Glennys Farrar of New York University and colleagues said that the smaller cluster was moving too fast for gravity alone to be responsible. They suggested that some mysterious force related to dark matter might be hurrying it along.













Still, two clusters is not a lot to go on. Dawson, Bullock and colleagues are following up with about 20 more galactic collisions to see if they show any unusual behaviours. "I really think that we're almost to the point where we have enough observational data in hand," Dawson said. "We could close the book on self-interacting dark matter."












If the new force does exist, we might soon be able to see its effects on things influenced by dark matter, such as the behavior of black holes or the masses of the first stars, says Douglas Finkbeiner of Harvard University in Cambridge, Massachusetts, who was not involved in the new study.












"The simple thing isn't always the right thing, so I really appreciate that Will is trying to look into these other possibilities," he says.












Louis Strigari of Stanford University in California agrees. "Self-interacting dark matter is worth pursuing because we're still very ignorant," he said. "We're desperate to understand what dark matter is, so any new window is welcome."

Google's Schmidt urges North Korea Internet freedom






BEIJING: Google chairman Eric Schmidt told North Korean officials their country would never develop unless it embraced Internet freedom, he said on Thursday as he returned from a visit to Pyongyang.

Former US ambassador to the United Nations Bill Richardson, who led the trip, urged North Korea to adopt a moratorium on ballistic missiles and nuclear tests following the communist state's widely criticised rocket launch last month.

Schmidt said he told North Korean officials they should open up the country's Internet "or they will remain behind".

"As the world becomes increasingly connected, their decision to be virtually isolated is very much going to affect their physical world, their economic growth and so forth, and it will make it harder for them to catch up economically," he said.

"Once the Internet starts, citizens in a country can certainly build on top of it. The government has to do something. It has to make it possible for people to use the Internet which the government in North Korea has not yet done."

Richardson, also a former governor of New Mexico, said: "We strongly urged the North Koreans to proceed with a moratorium on ballistic missiles and possible nuclear test."

The pair told reporters at Beijing airport that they did not meet North Korean leader Kim Jong-Un on the trip, or US citizen Kenneth Bae.

Bae was arrested in November after entering the country as a tourist, according to the North's official news agency, which said he had admitted committing a crime against the state.

Google's Schmidt presses North Korean officials for open Web

Eric Schmidt wrapped up a controversial visit to North Korea on Thursday, saying that his private delegation warned officials that global Internet access was key to developing its economy.


"As the world becomes increasingly connected, their decision to be virtually isolated is very much going to affect their view of the world," he told reporters upon his return to Beijing, according to a Wall Street Journal account. Lack of such access would "make it harder for them to catch up economically. We made that alternative very, very clear," he added.


Despite official U.S. opposition to the visit, Google's executive chairman flew to the reclusive nation on Monday as part of a delegation led by former New Mexico Gov. Bill Richardson, who described the trip as a "private humanitarian mission."


"We had a good opportunity to talk about expanding the Internet and cell phones in the DPRK," Richardson told the Associated Press before departing for Beijing.




The U.S. State Department had discouraged the visit, saying that the timing was not right for the delegation to visit the country, which is subject to U.S. economic sanctions. A department spokesperson cited recent missile launches by North Korea as a reason for opposing the visit


During the visit, the delegation, which also included Jared Cohen, head of Google Ideas, got a tour of a computer lab at Kim Il Sung University Pyongyang, where a student showed how he goes online to look at reading material from Cornell University.


It's unclear whether the delegation had the opportunity to inquire about Kenneth Bae, a Korean-American whose arrest on unspecified charges was announced by the North Koreans last month.

Embryonic Sharks Freeze to Avoid Detection

Jane J. Lee


Although shark pups are born with all the equipment they'll ever need to defend themselves and hunt down food, developing embryos still stuck in their egg cases are vulnerable to predators. But a new study finds that even these baby sharks can detect a potential predator, and play possum to avoid being eaten.

Every living thing gives off a weak electrical field. Sharks can sense this with a series of pores—called the ampullae of Lorenzini—on their heads and around their eyes, and some species rely on this electrosensory ability to find food buried in the seafloor. (See pictures of electroreceptive fish.)

Two previous studies on the spotted catshark (Scyliorhinus canicula) and the clearnose skate (Raja eglanteria)—a relative of sharks—found similar freezing behavior in their young. But new research by shark biologist and doctoral student Ryan Kempster at the University of Western Australia has given scientists a more thorough understanding of this behavior.

It all started because Kempster wanted to build a better shark repellent. Since he needed to know how sharks respond to electrical fields, Kempster decided to use embryos. "It's very hard to test this in the field because you need to get repeated responses," he said. And you can't always get the same shark to cooperate multiple times. "But we could use embryos because they're contained within an egg case."

Cloaking Themselves

So Kempster got his hands on 11 brownbanded bamboo shark (Chiloscyllium punctatum) embryos and tested their reactions to the simulated weak electrical field of a predator. (Popular pictures: Bamboo shark swallowed whole—by another shark.)

In a study published today in the journal PLoS One, Kempster and his colleagues report that all of the embryonic bamboo sharks, once they reached later stages of development, reacted to the electrical field by ceasing gill movements (essentially, holding their breath), curling their tails around their bodies, and freezing.

A bamboo shark embryo normally beats its tail to move fresh seawater in and out of its egg case. But that generates odor cues and small water currents that can give away its position. The beating of its gills as it breathes also generates an electrical field that predators can use to find it.

"So it cloaks itself," said neuroecologist Joseph Sisneros, at the University of Washington in Seattle, who was not involved in the study. "[The embryo] shuts down any odor cues, water movement, and its own electrical signal."

Sisneros, who conducted the previous clearnose skate work, is delighted to see that this shark species also reacts to external electrical fields and said it would be great to see whether this is something all shark, skate, and ray embryos do.

Marine biologist Stephen Kajiura, at Florida Atlantic University, is curious to know how well the simulated electrical fields compare to the bamboo shark's natural predators—the experimental field was on the higher end of the range normally given off.

"[But] they did a good job with [the study]," Kajiura said. "They certainly did a more thorough study than anyone else has done."

Electrifying Protection?

In addition to the freezing behavior he recorded in the bamboo shark embryos, Kempster found that the shark pups remembered the electrical field signal when it was presented again within 40 minutes and that they wouldn't respond as strongly to subsequent exposures as they did initially.

This is important for developing shark repellents, he said, since some of them use electrical fields to ward off the animals. "So if you were using a shark repellent, you would need to change the current over a 20- to 30-minute period so the shark doesn't get used to that field."

Kempster envisions using electrical fields to not only keep humans safe but to protect sharks as well. Shark populations have been on the decline for decades, due partly to ending up as bycatch, or accidental catches, in the nets and on the longlines of fishers targeting other animals.

A 2006 study estimated that as much as 70 percent of landings, by weight, in the Spanish surface longline fleet were sharks, while a 2007 report found that eight million sharks are hooked each year off the coast of southern Africa. (Read about the global fisheries crisis in National Geographic magazine.)

"If we can produce something effective, it could be used in the fishing industry to reduce shark bycatch," Kempster said. "In [America] at the moment, they're doing quite a lot of work trying to produce electromagnetic fish hooks." The eventual hope is that if these hooks repel the sharks, they won't accidentally end up on longlines.

Holmes 'Delighted' by Creepy Self-Portraits: Victims













After two days of apparent indifference, accused Aurora shooter James Holmessmiled and smirked at disturbing self-portraits and images of weapons shown in court today, according to the families of victims who watched him.


"When he sees himself, he gets very excited and his eyes crinkle," Caren Teves said outside of the courthouse, after the hearing. "Your eyes are the window to the soul and you could see that he was very delighted in seeing himself in that manner."


Teves' son Alex Teves, 24, died in the shooting.


Prosecutors showed photos that Holmes took of himself hours before he allegedly carried out a massacre at a Colorado movie theater. He took a series of menacing self-portraits with his dyed orange hair curling out of from under a black skull cap and his eyes covered with black contacts. In some of the photos, guns were visible.


Those haunting photographs, found on his iPhone, were shown in court today on the last day of a preliminary testimony that will lead to a decision on whether the case will go to trial. The hearing concluded without Holmes' defense calling any witnesses.


The judge's decision on whether the case will proceed to trial is expected on Friday.








James Holmes: Suspect in Aurora Movie Theatre Shootings Back in Court Watch Video









Police Testify at Hearing for Accused Colorado Gunman Watch Video









Couple Surprised by Rebuilt Home After Sandy Watch Video





Holmes, 25, is accused of opening fire on a crowded movie theater in Aurora, Colo., on July 20, 2012, killing 12 people and wounding dozens others during a showing of "Dark Knight Rises."


The court room's set-up kept members of the media from being able to see Holmes' face as the photos were displayed, but victims and their families could watch him.


Teves said that Holmes was "absolutely smirking" when images of his weapons and the iPhone photos he took of himself were shown in court.


"I watched him intently," Caren Teves' husband Tom Teves said. "I watched him smile every time a weapon was discussed, every time they talked about his apartment and how he had it set up (with booby traps), and he could have gave a darn about the people, to be quite frank. But he's not crazy one bit. He's very, very cold. He's very, very calculated."


Holmes' has exhibited bizarre behavior after the shooting and while in custody. His defense team has said that he is mentally ill, but have not said if he will plead insanity.


"He has a brain set that no one here can understand and we want to call him crazy because we want to make that feel better in our society, but we have to accept the fact that there are evil people in our society that enjoy killing any type of living thing," a frustrated Tom Teves said. "That doesn't make them crazy. And don't pretend he's crazy. He's not crazy."


The photos presented in court showed Holmes mugging for his iPhone camera just hours before the shooting.

Half-a-dozen photos showed Holmes with his clownish red-orange hair and black contact lenses giving the photos a particularly disturbing edge.


In one particularly odd image, he was making a scowling face with his tongue out. He was whistling in another photo. Holmes is smiling in his black contacts and flaming hair in yet another with the muzzle of one of his Glock pistols in the forefront.


Yet another photo showed him dressed in black tactical gear, posing with an AR-15 rifle.

Pruney fingers give us better grip underwater









































WHY do our fingers do prune impressions when soaked? It could be an adaptation that gives us better grip underwater.












Fingers and toes wrinkle in water after about 5 minutes due to the constriction of blood vessels. This reduction in volume pulls the skin inward, but as the skin's surface area cannot change, it wrinkles. A study in 2011 showed that wrinkles form a pattern of channels that divert water away from the fingertip – akin to rain treads on tyres. The team thought that this could aid grip.












To find out, Tom Smulders and his team at Newcastle University, UK, timed people as they transferred wet or dry objects from one box to another with and without wrinkled fingers.












With wrinkles, wet objects were transferred about 12 per cent faster than with unwrinkled fingers. The time it took to transfer dry objects was the same regardless of wrinkles.












So why aren't our digits always prune-like? "With wrinkles, less of your skin surface touches the object, so there may be issues of sensitivity," Smulders suggests.

China economy to overtake US by 2019: state research






BEIJING: China will overtake the United States economically within six years, an official research institute predicts, and go on to become the world's most important country in three decades more, state media said Wednesday.

The findings came from the Nation's Health Report issued by the Chinese Academy of Sciences, the Global Times said, without giving details of the criteria used for the prediction.

China's economy would be larger than that of the US by 2019, it cited the document as saying, and China's "international status" would exceed that of the US by 2049, the 100th anniversary of the founding of the People's Republic.

"National health" was defined as a country's "overall conditions... using resource sufficiency and wealth distribution as the major criteria", the Global Times said, but did not go into specifics.

China ranked as the 11th "healthiest" country out of some 100 nations, it said, just behind Costa Rica, with Sweden in top position.

The official Xinhua news agency said China was given a national health status of "up to standard", though the US, Japan and Britain were deemed "health deficient".

The report could not immediately be independently obtained from the Chinese Academy of Sciences.

China's stunning economic growth rates, increases in military spending and overlapping security interests in the Asia-Pacific region with the US have sparked concerns the countries could find themselves increasingly at odds in coming decades as they jockey for global influence.

But the Global Times, which has close ties to China's ruling Communist Party, said the document's findings were seen by some as overly nationalistic.

"The report is indicative of an anti-US sentiment in Chinese society," Fang Zhouzi, described as a prominent whistleblower on academic fraud, told the paper.

"It casts the US as a potential threat and links the goals of China's national revival to surpassing the US," he added.

Decades of economic reform and openness to foreign investment have propelled China from a poor, overwhelmingly agricultural country to become the world's second-largest economy behind the US.

International analysts widely expect China's economy, given its high growth rates, to overtake the US in terms of gross domestic product, or total size, sometime in the first half of this century, though differ on exact timing and criteria.

But they also see the US as likely to remain wealthier on a per capita basis given China's huge population of 1.3 billion, with that of the US currently at about 315 million.

BlackBerrify your iPhone with Spike keyboard case




LAS VEGAS--No one likes typing on a touch screen. So what if your iPhone case had a very mini QWERTY keyboard?


That's just what Spike from SoloMatrix is designed to be. When we heard about it last year, the Spike TypeSmart keyboard was part of a Kickstarter campaign that proved successful.


The tactile keyboard swivels out from its case and its keys make contact with the iPhone's on-screen keyboard.


It doesn't require separate charging, docking, or an app, and it works with capacitive conductivity through the screens on the
iPhone 4 and
iPhone 5.




Whenever a key is pressed and makes contact with the screen, it creates a grounded state.


Spike attaches to the phones in a snap. There's a number key that pushes the number menu on the iPhone's on-screen keyboard. Then you can type using the alternate number designations for the TypeSmart.


But your fingers better be very nimble indeed to get the hang of it. When I tried typing a few sentences, certain keys didn't register and words were missing letters.


I have a BlackBerry Curve, and there's really no comparison between the ease of use of its keyboard and Spike. The former wins hands down.


But if you want something very compact that doesn't require separate power or Bluetooth, Spike may be worth considering.


The iPhone 4/4s version will launch in February for $49.95, with the iPhone 5 edition following.


The price may drop if there's high order volume, according to Cody Solomon, SoloMatrix co-founder.


Since the campaign raised some $81,000, Spike could prove popular indeed.
