SUNSTOP writes to tell us that a relatively unknown Maryland scientist has proposed a public patent that he claims could combat global warming. The proposed plan would require massive amounts of water to be sprayed into the air in an effort to bolster the earth's existing air conditioning system. "First, the sprayed droplets would transform to water vapor, a change that absorbs thermal energy near ground level; then the rising vapor would condense into sunlight-reflecting clouds and cooling rain, releasing much of the stored energy into space in the form of infrared radiation. Kenneth Caldeira, a climate scientist for the Carnegie Institution's Department of Global Ecology at Stanford University whose computer simulation of Ace's invention suggests it would significantly cool the planet. The simulated evaporation of about one-half inch of additional water everywhere in the world produced immediate planetary cooling effects that were projected to reach nearly 1 degree Fahrenheit within 20 or 30 years, Caldeira said."

ruheling writes "From yesterday's New York Times: ' What Has Driven Women Out of Computer Science?' In many US universities, over the past decade, there has been deliberate effort to integrate and encourage women and girls to get more involved in the 'hard' sciences, engineering, and math. However, instead of the proportion of women to men increasing, in Computer Science the opposite is actually true. Specifically, in 2001-2, only 28 percent of all undergraduate degrees in computer science went to women. Now many computer science departments report that women now make up less than 10 percent of the newest undergraduates. What's going on here, folks?"

Yesterday we discussed the war and how foreign policy will matter in your decision next Tuesday. Today our series of election discussion pieces continues with Health Care. With an obesity epidemic, a failing economy, and ballooning health care costs, which candidate has the best answers to making sure that Americans are able to stay healthy without America being bankrupted in the process?

aaandre writes with word of a Washington Post story which begins: "The Maryland State Police classified 53 nonviolent activists as terrorists and entered their names and personal information into state and federal databases that track terrorism suspects, the state police chief acknowledged yesterday. The police also entered the activists' names into the federal Washington-Baltimore High Intensity Drug Trafficking Area database, which tracks suspected terrorists. One well-known antiwar activist from Baltimore, Max Obuszewski, was singled out in the intelligence logs released by the ACLU, which described a 'primary crime' of 'terrorism-anti-government' and a 'secondary crime' of 'terrorism-anti-war protesters.'" According to the article, "Both [former state police superintendent Thomas] Hutchins and [Maryland Police Superintendent Terrence] Sheridan said the activists' names were entered into the state police database as terrorists partly because the software offered limited options for classifying entries." Reader kcurtis adds "The State Police say they are purging the data, but this is one more example (on top of yesterday's news that datamining for terrorists is not feasible due to false positives) of just how badly the use of these lists can be abused."

An anonymous reader writes "US News makes a mint off its college rankings every year, but do they really give meaningful information? A pair of mathematicians argues that the data the magazine uses is all likely to be at least somewhat relevant, but that the way the magazine weights the different statistics is pretty arbitrary. After all, different people may have different priorities. So they developed a method to compute the rankings based on any possible set of priorities. To do it, they had to reverse-engineer some of US News's data. What they found was that some colleges come out on top pretty much regardless of the prioritization, but others move around quite a lot. And the top-ranked university can vary tremendously. Penn State, which is #48 using US News's methodology, could be the best university in the country, by other standards."

TechDirt is reporting that those all-too-familiar "stats" surrounding the cost of piracy are being trotted out in an attempt to push through a new "Copyright Czar" position. "In urging President Bush to sign into law the ProIP bill, which would give him a copyright czar (something the Justice Department had said it doesn't want), the US Chamber of Commerce is claiming that 750,000 American jobs have been lost to piracy. Yet, it doesn't cite where that number comes from."

Nobel Prize season is here again, and the first award for Physiology or Medicine was split between two virologists who discovered HIV and one who demonstrated that a virus causes cervical cancer. Coming soon is the announcement for Physics. Look to the right for a chance to pit your selection wit against the Royal Swedish Academy of Sciences with a poll for which scientific achievement deserves the prize. Front runners, according to Reuters, are; Andre Geim and Kostya Novoselov, discovers of graphene, Vera Rubin, provider of the best evidence yet of dark matter, and Roger Penrose and Dan Shechtman, discoverers of Penrose tilings and quasicrystals.
