CDC: Flu Outbreak Could Be Waning

The flu season appears to be waning in some parts of the country, but that doesn't mean it won't make a comeback in the next few weeks, according to the Centers for Disease Control and Prevention.

Five fewer states reported high flu activity levels in the first week of January than the 29 that reported high activity levels in the last week of December, according to the CDC's weekly flu report. This week, 24 states reported high illness levels, 16 reported moderate levels, five reported low levels and one reported minimal levels, suggesting that the flu season peaked in the last week of December.

"It may be decreasing in some areas, but that's hard to predict," CDC Director Dr. Thomas Frieden said in a Friday morning teleconference. "Trends only in the next week or two will show whether we have in fact crossed the peak."

The flu season usually peaks in February or March, not December, said Dr. Jon Abramson, who specializes in pediatric infectious diseases at Wake Forest Baptist Health in North Carolina. He said the season started early with a dominant H3N2 strain, which was last seen a decade ago, in 2002-03. That year, the flu season also ended early.

Because of the holiday season, Frieden said the data may have been skewed.

For instance, Connecticut appeared to be having a lighter flu season than other northeastern states at the end of December, but the state said it could have been a result of college winter break. College student health centers account for a large percentage of flu reports in Connecticut, but they've been closed since the fall semester ended, said William Gerrish, a spokesman for the state's department of public health.

The flu season arrived about a month early this year in parts of the South and the East, but it may only just be starting to take hold of states in the West, Frieden said. California is still showing "minimal" flu on the CDC's map, but that doesn't mean it will stay that way.

"It's not surprising. Influenza ebbs and flows during the flu season," Frieden said. "The only thing predictable about the flu is that it is unpredictable."

Dr. William Schaffner, chair of preventive medicine at Vanderbilt University Medical Center in Nashville, Tenn., said he was expecting California's seeming good luck with the flu to be over this week.

"Flu is fickle, we say," Schaffner said. "Influenza can be spotty. It can be more severe in one community than another for reasons incompletely understood."

Early CDC estimates indicate that this year's flu vaccine is 62 percent effective, meaning people who have been vaccinated are 62 percent less likely to need to see a doctor for flu treatment, Frieden said.

Although the shot has been generally believed to be more effective for children than adults, there's not enough data this year to draw conclusions yet.

"The flu vaccine is far from perfect, but it's still by far the best tool we have to prevent flu," Frieden said, adding that most of the 130 million vaccine doses have already been administered. "We're hearing of shortages of the vaccine, so if you haven't been vaccinated and want to be, it's better late than never."

Your body's insights into life and cosmos

The human body has some surprising stories to tell about the nature of our species, planet and universe, reveals The Universe Within by polymath Neil Shubin

POLYMATHS are a dying breed. We have amassed so much information since the Enlightenment that it is difficult to make a mark by generalising: specialism is king.

In The Universe Within, evolutionary biologist Neil Shubin shares the findings of some of the great scientific specialists - as well as those of a few unsung heroes. But he also explains how a generalist's appreciation of their work is still possible, simply by looking inside the human body. Within each of us is a multitude of memory aids that, when read correctly, help to tell the stories of our species, planet and universe.

Take our warm-blooded physiology, for instance. Shubin shows how the rise of mammals was made possible because the Atlantic Ocean began to open up about 200 million years ago. This created new coastlines, triggering erosion that dumped sand into the ocean. Undersea muck that normally consumed oxygen as it decomposed was sealed off by the sand, freeing more oxygen into the atmosphere and causing concentrations to rise to present levels. This boost gave us warm blooded creatures the vital ingredient we needed to fuel our aerobic metabolism and thrive. So our body temperature serves as a reminder of the way plate tectonics can influence evolution.

Shubin's book is filled with such sweeping scientific stories, sewn into a broader narrative - the tale of his first palaeontological exploration of Greenland. He often begins with tales from his first experiences of Arctic life, making chapters impressively broad in scope - but also prone to meandering. Still, one take-home message is clear throughout: just how much we can learn about the complex scientific world outside by looking within.

Two world-shaping visionaries who missed their targets

Simon Ings, contributor

THIS is a book about two men who shaped our generation. The first, Gerard K. O'Neill, drew up more or less workable plans for colonies in space. The second, O'Neill's student K. Eric Drexler, dreamed of mastering matter at the molecular scale to build the world and the body anew.

Forty years on, and through the lens of Patrick McCray's thoughtful, meticulous history, it is clear that O'Neill and Drexler changed our world more profoundly and completely than their critics thought possible. At the same time, their influence was far less direct and predictable than they or their supporters expected.

In their own ways, and more or less by accident, O'Neill and Drexler laid the ideological groundwork for Silicon Valley. And their essays, published in science fiction and cyberculture magazines - O'Neill's in Omni and Drexler's in Mondo 2000 - each promised redemptive and epochal fixes for all our economic, ecological and moral ills.

But as The Visioneers goes some way towards explaining, cultish enthusiasm and popular incredulity can together squeeze the life out of revolutionary ideas. Those interested in the impact of mavericks and pioneers should read McCray's twin-barrelled analysis of what it means to aim for the stars - and miss.

Malaysia prepares for joint opposition mega-rally

KUALA LUMPUR: Malaysia is preparing for a big rally on Saturday - what organisers are calling the People's Uprising rally.

It is the first of its kind, bringing together opposition parties and non-governmental organisations.

Dubbed the KL112, the mega rally this Saturday promises to be a historic event for the country.

The rally venue, Merdeka stadium, is a heritage site and the management has limited its capacity to no more than 30,000, even though organisers are expecting a million people.

Once the stadium reaches its saturation point, the crowd will have to gather outside the stadium at the parking lot as well as the adjacent Victoria field.

The organisers have paid US$30,000 to the management as deposit to use the venue and signed an agreement with the police to gather peacefully.

Rally goers must not bring children or they can be arrested and prosecuted.

Meanwhile, the Education Ministry has warned teachers and students not to participate in the so-called politically motivated rally.

Chief secretary to the government Ali Hamsa also advised civil servants not to be involved in the rally.

Parents were told to discourage their children from attending.

Still, thousands of university and college students have confirmed their attendance.

In fact, they will be going for a pre-rally countdown on Friday evening at Kampong Baru, not too far from here.

On Saturday, they will be joining others at eight main gathering points in the city before making their way to Merdeka stadium for the People's Uprising rally, that is scheduled to go on between 2 and 5pm local time.

Google revs Chrome for Android faster with new beta release

Android users who want to live an edgier life now can try a beta version of Chrome.

Google yesterday released the Chrome 25 beta for Android 4.x smartphones and
tablets, a version number in sync with the release for personal computers. Previously, the only option was the stable version of Chrome for
Android, which is still way back at version 18.

The Chrome for Android beta is available on the Google Play app store, but only by following that link -- it's not visible in Google Play's search, Google said. The beta version can be installed and run side by side with the stable version.

Google has been working to put Chrome for Android on the same six-week update cycle as the personal computer version of the browser, and it looks like this release is part of that change. The Chrome 25 beta brings a number of new features, but Google warns of sluggish performance and some other problems.

Among the new features, according to Chrome developer Peter Beverloo:

• A new "text autosizing" technique for formatting text on mobile-device screens, drawing in part upon "font inflation" work by Mozilla. Sometimes it seems to cause Chrome to display different areas of text in mismatched font sizes, though.

• Faster JavaScript performance trough use of a newer version of Google's V8 software.

• A range of developer-oriented features such as CSS filters for visual effects, dynamic viewport units for better handling of screen-size and pixel-size variations, IndexedDB for offline data storage and other data-handling needs, and flexbox layout abilities for more adaptable formatting.

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

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.

India's Kingfisher airline boss promises restart

MUMBAI: The boss of India's troubled Kingfisher airline has sought to allay fears about jobs in a rare communication to staff, which outlines plans to restart limited operations and win a foreign investment deal.

Kingfisher, whose operations have been grounded since October, lost permission to fly after a deadline to renew its suspended licence with the aviation regulator expired at the start of the new year.

Vijay Mallya's email, sent late Wednesday, expressed hopes for a limited re-start of flights from March this year, requiring funding of 6.5 billion rupees (US$118 million) which would be provided by the airline's parent UB Group.

The airline has submitted a detailed restart plan to the regulator, he said, also reiterating that there were "discussions with multiple investors", including Abu Dhabi-based Etihad Airways, to sell a stake in the airline.

"We remain confident that we will secure a deal," he wrote in the email seen by AFP.

The firm's shares jumped 9.96 per cent to 14.79 rupees on the Bombay Stock Exchange on Thursday.

Many staff are owed months of pay. Some of them have threatened to approach a court seeking formal closure of the airline if they are unconvinced about the management's revival plan and its ability to pay pending salaries.

Mallya said Kingfisher "was on safe ground" to renew its flying licence with the regulator, which can be applied for within two years after the date of expiry.

"We need to single-mindedly focus on being back in the air and to win back the confidence of our loyal guests," he wrote.

The Centre for Aviation, a Sydney-based consultancy, said in a recent report Kingfisher had accumulated losses of US$1.9 billion and debts of US$2.49 billion, including bank debts of US$1.1 billion.

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.
