UK regulators approve Vodafone and O2's network merger

Vodafone and O2's network tieup gets regulators approval in the fight against EE's LTE begins in earnest

Observing the mantra that the enemy of its enemy is its friend, Vodafone and O2 have gained regulatory approval to begin merging their cellular networks to better compete with Everything Everywhere. As such, they can begin spinning off infrastructure and towers to a new company called CTI, which will manage both company's hardware as a single network. It's hoped the new tie-up will cover 98 percent of the country and enable LTE services to roll out two years ahead of Ofcom's 2017 deadline. Worried about another awkward T-Mobile and Orange-style merger? Don't be, since in every other respect, the pair have pledged to operate as competing entities in a quest for your custom.

Evolutionary analysis improves ability to predict the spread of flu

ScienceDaily (Oct. 1, 2012) ? With flu season around the corner, getting a seasonal vaccine might be one of the best ways to prevent people from getting sick. These vaccines only work, however, if their developers have accurately predicted which strains of the virus are likely to be active in the coming season because vaccines must be developed in advance of the upcoming flu season. Recently, a team of scientists from Germany and the United Kingdom have improved the prediction methods used to determine which strains of the flu virus to include in the current season's vaccine.

The research describing this advance is published in the October 2012 issue of Genetics.

"Seasonal influenza kills about half a million people per year, but improved vaccines can curb this number," said Michael L?ssig, Ph.D., a researcher involved in the work from the Institute for Theoretical Physics at the University of Cologne in K?ln, Germany. "Although this study is some distance from direct applications, it is a necessary step toward improved prediction methods. We hope that it helps yield better vaccines against influenza," L?ssig added.

To make this advance, scientists analyzed the DNA sequences of thousands of influenza strains isolated from patients worldwide, dating to 1968. By analyzing this dataset, researchers were able to determine which strains were most successful at expanding into the entire population, and which mutations were least successful in spreading. Using a new statistical method, the researchers found that many more mutations than we thought initially succeed in replicating and surviving. These mutations compete; some make it into the entire population, others die out. This analysis of the virus enables prediction of trends which can help vaccine developers understand the rules of flu virus evolution. This knowledge, in turn, can be used to predict which strains of the virus are most likely to spread through a human population.

"Every year, new concerns emerge about 'super flus' that have the potential to kill many people," said Mark Johnston, Editor-in-Chief of the journal Genetics. "This research itself will not stop any people from getting sick, but it could give us a heads up to particularly dangerous strains that might be on the horizon. With that information, we may be able to develop increasingly effective vaccines."

This work was partially supported by the Wellcome Trust [080711/ Z/06] (N.S.) and by Deutsche Forschungsgemeinschaft grant SFB 680 (to M.L.). This work was also supported in part by the National Science Foundation under grant PHY05-51164 during a visit to the Kavli Institute of Theoretical Physics (University of California, Santa Barbara).

Presidential debate: what to look for beyond who wins or loses

Political spin coming out of the presidential debate Wednesday will be fierce. But the savvy viewer looks for more than winner and losers. Here's a guide to viewing the presidential debate.

By Amanda Paulson,?Staff writer / October 1, 2012

In the minutes and days immediately following Wednesday's presidential debate in Denver ? the first of four general-election debates on the calendar ? expect the spin to come fast and furious.

The No. 1 question that will be asked ? and answered, in differing ways: Who won?

According to some civic groups, though, that isn't the most interesting or even the most important aspect to come out of the debates.

In a wide-reaching discussion Monday with journalists and academics ? including veteran broadcast journalist Sander Vanocur, who served as a panelist in the first Nixon-Kennedy debate in 1960 ? the Newseum's First Amendment Center and the National Communication Association explored what else citizens watching the debates should look for to get the most insight into the candidates.

Some of their tips:

  • Watch with people who have different politics from you, so you can get their take on how each candidate is doing, rather than just seeing the debate through the lens of your own biases.
  • Do a little homework on the issues before watching so you don't have to take what the candidates say as truth (and be prepared to fact check afterward at one or more of the reputable fact-checking sites out there).
  • Try to weigh which candidate has a greater grasp of the facts and information, and how honest they are.
  • Watch the candidates' nonverbal cues as well as their verbal ones. (Remember Al Gore's famous sighs from his first debate against George W. Bush? Or how often the first President Bush checked his watch in his debate against Bill Clinton?) How well do the nonverbal signs match what they're saying? Is there a lot of sneering going on as the other person speaks?
  • Watch how well the candidates walk the line of being polite, without backing down. This is the first time sharing the stage amid a particularly acrimonious campaign, with negative ads on both sides, but most voters don't want to see signs of personal antipathy in the debate.

Things have changed a lot since the first modern presidential debate was held between Richard Nixon and John F. Kennedy in 1960 (and not again until 1976). Back then, Mr. Vanocur remembered, he got just two days notice that there would be a debate and he'd be asking some questions.

Much has been made since then of the role the debates had in that election ? and particularly the lack of awareness on the part of Mr. Nixon and his team as to how appearance and visuals would factor into the public's perception ? though recent studies have shown that, at the time, the appearance story didn't dominate coverage of the debate, notes Kathryn Olson, a professor at the University of Wisconsin in Milwaukee. Instead, the suggestion that what really mattered in the debate was Nixon's clothes and his lack of makeup has been amplified and simplified over the years.
