Q: (CNN) -- On Tuesday, a federal advisory panel, the National Science Advisory Board for Biosecurity, recommended that university scientists who have submitted articles on how to modify a flu virus to two very prestigious journals delete critical information from them before publishing. The papers describe how to alter bird-flu virus to be more infectious and potentially nastier. Yes, this is same bird flu virus that, as it moved into pigs, was freaking us all out last year. If you had the detailed map of the viral changes needed, then either a terrorist or an amateur "garage" biologist operating without the right safeguards would have a very effective critter for killing you and me. If there is one thing that scientists hate, it is any policy that restricts research in any way. Scientists are taught that they need to be bold in asking questions and not let anything deter them from following their thinking wherever it leads, no matter how unpopular that might be. They are also taught the absolute necessity of making their claims public in reputable journals so that other scientists can subject them to the critical skepticism from which the truth ultimately emerges. Once in a long while, however, the price of the truth is simply too high to let scientists disclose their findings publicly. That is so when it comes to publishing detailed information about dangerous viruses and microbes. We don't have to hide the genetic map for a killer avian flu virus from all eyes. Access to some who have clearance to see it should be possible. If that is done, then the truth will still be known about whether those making claims of being able to engineer the virus can actually do so. To go further with potentially catastrophic data is to court trouble. There are those who will say that the only way to fight terror is to adhere to those values that have proven crucial to the advance of science over the decades. The more we know, the worse for the terrorists. Unfortunately, that is no longer the world we live in. The ethics of inquiry need to adapt. Handing the complete formula for making a nasty pandemic bug to any nut with access to the Internet or a subscription to a scientific journal makes no sense in a world that has seen the use of anthrax and sarin as weapons of terror. Freedom is key to good science. Freedom from terror is also key to good science. When they conflict, the latter is more important freedom than the former. Journals and those who write for them ought to do all they can to try and ensure that most important freedom. The opinions expressed in this commentary are solely those of Arthur Caplan.

Q: (CNN) -- Cristiano Ronaldo has urged his Real Madrid teammates to carry their recent impressive form into the New Year after they cut Barcelona's lead at the top of Spain's La Liga to two points. The Portugal international scored a spectacular goal as Real kept the pressure up on defending champions Barca with an emphatic 6-0 victory over Real Zaragoza. But Ronaldo does not want his colleagues to take their foot of the gas and keep the pressure on the Catalan side, who won the Club World Cup in Abu Dhabi, when the season resumes again on January 2 after the winter break. "It was important to seal the year with a victory, so we are happy about that. We must all now think of the New Year, which we should start as well as we've ended this one," Ronaldo told the club's Web site. "I'm working well and I want to carry on this way until the end of the season. I'm doing better every day. I missed two months and coming back was difficult, but things are working out for me." Real coach Manuel Pellegrini also paid tribute to Barcelona for an amazing 12 months in which they added the Club World Cup trophy to victory in La Liga, the Copa del Rey, Champions League and European and Spanish Super Cup titles. "What Barcelona have achieved is a great feat and hard to emulate. But there is also great merit in just being two points behind them on the table," he said. "We've played well away from home against the teams that earned the most points last year. Barcelona's excellent performances add to our own merit." Meanwhile, Hugo Sanchez become the fourth La Liga manager to lose his job his season after he was sacked by Almeria following their 2-0 away defeat to Espanyol which left them a point above the relegation zone. Almeria had lost eight of their 15 games in La Liga this season and the Mexican has been replaced by Constantin Galca, the coach of Almeria's B team, on a temporary basis.

Q: (CNN) -- Hating the Internal Revenue Service is an American pastime that transcends political affiliation. This past May, disgust for the IRS reached an all-time high when Lois Lerner, director of the IRS's Exempt Organizations unit, disclosed the agency had improperly targeted social welfare organizations seeking special status under section 501(c)(4) of the tax code based on their political ideology. This revelation resulted in more than three months (and counting) of congressional hearings and investigations. Read the IRS inspector general's report on targeting . But in typical Washington fashion, the manufactured congressional outrage and grandstanding has served to do little more than obfuscate the real scandal at the IRS: that the agency allows social welfare organizations to manipulate federal tax law by spending hundreds of millions of dollars on political ads. Anyone who watched television in the lead-up to the 2010 and 2012 elections undoubtedly noticed the slew of vitriolic, misleading campaign ads. Some of these ads were sponsored by federal candidates, but many more were produced by groups with innocuous sounding names -- such as Crossroads GPS or the American Action Network -- but massive bank accounts. Crossroads GPS, for example, a nonprofit organization cofounded by former George W. Bush administration official Karl Rove, spent more than $70 million on the 2012 election. Like the groups targeted by the IRS, Crossroads GPS is a section 501(c)(4) organization, which affords certain tax benefits and -- most importantly -- the ability to keep the names of donors secret. Federal law requires these groups to operate "exclusively for purposes beneficial to the community as a whole." IRS regulations, however, create a loophole in the law by allowing groups "primarily" engaged in these types of activities to benefit from this tax status. Many 501(c)(4) groups have interpreted this regulation to mean they can spend up to 49% of their funds on political activities -- mostly negative, deceptive political ads. Adding to the confusion, the IRS has said there is no specific percentage the agency uses to gauge whether a group has engaged "primarily" in social welfare activities, but rather that it considers all facts and circumstances. What does that mean exactly? No one knows. When directly confronted about the problem and the agency's record of inaction, the IRS has said only that it is "aware" of the issue. But the IRS has been aware of and has chosen to ignore this problem for more than 50 years. If the agency had revised its regulations at any point in the past as my organization and others requested, the agency might have avoided the quagmire in which it is drowning. Frustrated with the IRS's inaction, in May CREW filed a lawsuit against the IRS for flouting the law barring 501(c)(4) organizations from engaging in political activity. The case is pending in District of Columbia district court. Rep. Chris Van Hollen, D-Maryland, and other public interest groups filed a similar lawsuit last month. Because social welfare organizations are not required to disclose their donors, 501(c)(4) groups have become the de facto vehicle for millionaires, billionaires, and even corporations who want to remain anonymous while influencing our elections. As a result, politically active nonprofit groups spent more than $300 million on the 2012 election. Americans should not only be outraged that our elections are being flooded with anonymous cash, but because of the nonprofit status of these groups, taxpayers are subsidizing their activity. With more and more groups seeking to participate in federal elections using money raised from donors who want to remain anonymous, applications to the IRS for 501(c)(4) status more than doubled between 2010 and 2012. To manage the deluge, Lerner said the agency relied on code words and other shortcuts to single groups out for extra review. While the scrutiny of tea party groups has received the most attention, the IRS "Be on the Look Out" (BOLO) list also included the words "progressive," "occupy," and "Israel." Flagging any group for further screening because their applications included specific words or phrases was wrong. The impact, however, of such misguided actions on our democracy was negligible, particularly compared to that wrought by the IRS's failure to stop hundreds of millions of dollars from flooding our electoral system to influence our votes. For all of the abuse heaped upon the IRS and for all the concern about the BOLO list, the same thing could happen again if the disparity between the language of the statute and regulation is not addressed. Agents processing applications of groups seeking social welfare status in the future will remain as confused about the standards as those whose decisions have been questioned this year. Nevertheless, Congress has shown no appetite to pass legislation clarifying the requirements for these nonprofit groups. As the 2014 election cycle gets under way, the super rich and corporations with deep coffers will continue to buy our elections, and Congress will continue to spend time and resources on a never-ending cycle of investigations into a problem with a fairly easy solution: as Congress intended when it first passed the law, prohibit 501(c)(4) organizations from spending money on anything other than social welfare activities. As long as members of Congress do nothing other than one-up each other's disdain for the IRS, nothing will change. And that really is a scandal. Join us on Facebook/CNNOpinion.
