House Seeks To Pay For Reform With New Tax On Wealthy
House Democrats are expected to begin marking up a health reform bill this week that members of the Ways and Means committee said "would cost less than $1 trillion over 10 years, [and would be] paid for chiefly by a combination of spending reductions in the health care system and a surtax on wealthy taxpayers," CQ Politics reports. "The surtax would be levied beginning in 2011. ò€¦ [T]here would be three income brackets - $350,000, $500,000 and $1 million for couples filing jointly, and $280,000, $400,000 and $800,000 for individuals - with a different rate at each level: "One, two, three [percent] - something like that,"" the committee"s chairman, Charles Rangel, D-N.Y., said (Wayne, 7/13).

Uganda To Distribute ITNs To All Citizens
The Ugandan ministry of health said that everyone in the country will receive free insecticide-treated nets (ITNs) to prevent malaria beginning in September, James Kakooza, the state minister for primary health care, said, New Vision/allAfrica.com reports. Kakooza said children and mothers will be the priority, but that the goal is to make the 17.4 million imported ITNs available to everyone. The ITNs will supplement 6 million ITNs that were distributed over the last three years, Richard Ndyomugyenyi, the malaria control program officer, said.

Editorials, Opinion Pieces React To Kansas Abortion Provider Tiller's Murder
Several newspapers on Wednesday published editorials and opinion pieces responding to the shooting death of Kansas abortion provider George Tiller, who was one of the few physicians in the country providing care for women in need of the procedure later in pregnancy. Summaries appear below.Editorials~ Boston Globe: Although officials are calling Tiller"s murder ""the act of an isolated individual," ... the generalized culture of violence and hate in the antiabortion movement that feeds the fanaticism of disturbed individuals with guns is not so easily explained away," a Globe editorial states. The editorial notes, "Many responsible abortion opponents, including Americans United for Life, condemn the killing," but "other so-called pro-life leaders insist on finding a moral equivalence between Tiller"s murder and abortion." The editorial continues, "Also victimized by Tiller"s murder are the anguished women who have sought late-term abortions because their pregnancies have gone horribly wrong." According to the editorial, the "sad irony" is that these procedures "are not a matter of "choice,"" as the "overwhelming majority of these women desperately wanted their children to be born." It adds, "Tiller"s brave and compassionate care saved the lives of these women and their futures as mothers." In his speech last month at the University of Notre Dame"s commencement ceremony, President Obama "called for people of good will on both sides of the abortion issue to bridge the divide," the editorial states, concluding, "An end to the hateful rhetoric over issues of faith that lead unhinged individuals to murder would be a good place to start" (Boston Globe, 6/2).~ USA Today: Tiller"s "insistence" on continuing to practice, despite protests and threats of violence, "was remarkably courageous," but, "[r]egrettably, threats by antiabortion activists have worked all too well," a USA Today editorial states. According to the Guttmacher Institute, the number of abortion providers has decreased by 40% since a peak in 1982, and 87% of U.S. counties have no provider, forcing many women to travel long distances to obtain care, the editorial says. "Mainstream pro-life groups should not be blamed for the actions of a suspected killer who appears to have lurked in the violent and twisted fringe of the movement," the editorial continues. However, the "braying of cable TV hosts," such as Fox News" Bill O"Reilly, "and activists such as Operation Rescue founder Randall Terry contributes to a climate of intolerance that can encourage deranged individuals," the editorial says. According to USA Today, "Thwarted in legislatures and courts, some antiabortion activists are achieving with intimidation and harassment what they can"t through the political process," but "[r]egardless of personal beliefs about abortion, authorities have an obligation to protect those providing and receiving abortion services, and to prosecute those who harass or threaten them." The editorial concludes that "Tiller"s death will only be compounded if it frightens away more doctors and makes a legal procedure even harder to come by" (USA Today, 6/3).~ Washington Post: Tiller"s death "is a tragedy for his family, his patients and his profession," and "[i]t should serve as a wake-up call that more must be done to ensure that women have access to this legal procedure," a Post editorial states. "It is unclear how this violence has affected decisions by health care providers," according to the editorial. However, it is clear that "the number of places where women can go for abortions has been declining since 1982," and "[v]ery few are performed in hospitals -- a sign that mainline medicine is not living up to its responsibility," the editorial says. The editorial notes that Attorney General Eric Holder "is offering U.S. Marshals Service protection for abortion clinics and the doctors who staff them," concluding, "It"s the right call, but one that underscores the urgency of coming up with better solutions for the delive

New Biosensor Detects Extremely Low Bacteria Concentrations Quickly, Easily And Reliably

Bacterial diseases are usually detected by first enriching samples, then separating, identifying, and counting the bacteria. This type of procedure usually takes at least two days after arrival of the sample in the laboratory. Tests that work faster, in the field, and without complex sample preparation, whilst being precise and error-free, are thus high on the wish list. A Spanish research team headed by Jordi Riu and F. Xavier Rius at the University Rovira i Virgili in Tarragona has now developed a new technique to make this wish come true. With a novel biosensor, they have been able to detect extremely low concentrations of the typhus-inducing Salmonella typhi. As reported in the journal Angewandte Chemie, their new method is based on electrochemical measurements by means of carbon nanotubes equipped with aptamers as bacteria-specific binding sites. If bacteria bind to the aptamers, the researchers detect a change in electrical voltage. Aptamers are synthetic, short DNA or RNA strands that can be designed and made to bind a specific target molecule. An aptamer that specifically binds to salmonella has recently been developed. The Spanish researchers chose to use this aptamer for their biosensor. By means of additional functional groups, they securely anchored the aptamers to carbon nanotubes, which were deposited onto an electrode in an ultrathin layer. In the absence of salmonella, the aptamers fit closely against the walls of the carbon nanotubes. If the biosensor is put into a salmonella-containing sample, the microbes stick to the aptamers like flies to flypaper. This influences the interaction between the aptamers and the nanotubes, which makes a change in the electrode voltage noticeable within seconds. Using this biosensor, the researchers were able to detect a bacterial concentration equivalent to one salmonella bacterium in 5 mL of medium. Quantitative measurements were possible down to a concentration of about 1000 salmonella per milliliter. This biosensor is specific: it does not react to bacteria other than Salmonella typhi. "Our new technique makes the detection of micro-organisms as fast and simple as the measurement of pH value," say Riu and Rius.
