Three new reports by research teams in the U.S., Europe and Iceland have identified, for the first time, specific gene variants that appear to make some smokers and former smokers more susceptible than others to cancer. The two variants - or differences in a single nucleotide - exist in about 34% of the population and occur in genes in the same region of the long arm of chromosome 15. Those genes code for nicotinic acetylcholine receptors, cell-surface proteins that selectively bind to nicotine molecules. Once nicotine attaches to these receptors, a series of changes in the cells is triggered...
...prime culprits in word-stealing (though a less cynical man might hope that literary-minded young lovers just want to quote Elizabeth Barrett Browning to their sweethearts). Other teen love poem searches include: "love poems for MySpace," and "emo love poems" (referring to "emotional hardcore," a variant of punk rock), like these lines in the aptly named poem "ugh" submitted by a user by the name of colormebroken on the website GreatestJournal.com...
...Still, prostate cancer does kill some 30,000 men a year in U.S. Learning more about genetic predisposition, particularly through a test that does not require cancer to be present to determine risk (PSA screening does), may help lead to the way to identify gene markers for the lethal variant of the disease. "It's a step in the right direction," says Dr. William Isaacs, a professor of urology and oncology at the Brady Urological Institute at Johns Hopkins School of Medicine and a co-author of the study. "Who's at risk of a more aggressive disease? That...
...Second, a faith in the good intentions of the American nation spawns two types of arguments about Iraq. The first variant, largely confined to the political Right, connives to apportion blame for the ‘mess’ in Iraq to the Iraqis themselves. Aside from ignoring Coalition troops’ direct hand in Iraqi deaths (according to the Lancet study, 56 percent of all cases where a perpetrator was known, amounting to hundreds of thousands of Iraqis), not to mention their role in fomenting Iraq’s sectarian bloodshed, this claim whitewashes the gross illegality of their...
...second variant of the belief in American benevolence deserves closer scrutiny. Here the incorrectness of the invasion of Iraq is admitted, but a select cabal of criminals is held responsible. Yet not only does this willfully ignore the bipartisan makings of the occupation itself (from Democrats’ sanctioning the initial invasion to their pithy, insipid “opposition” today), it demonstrates a deep-seated refusal to engage the historical role of the Democratic Party in fashioning imperial policy. In the specific context of Iraq, one only has to point to the murderous regime of sanctions...
