There are some differences, such as direct action is not required, but the concept of guilt by association for not doing the right thing is still on the face of the bill."

Matt_dk writes "Scientists are now able to explain why Mars' residual southern ice cap is misplaced, thanks to data from ESA's Mars Express spacecraft (the same probe running the 'Mars Webcam'). It turns out the martian weather system is to blame. And so is the largest impact crater on Mars — even though it is nowhere near the south pole. Like Earth, Mars has frozen polar caps, but unlike Earth, these caps are made of carbon dioxide ice as well as water ice. During the southern hemisphere's summer, much of the ice cap sublimates, a process in which the ice turns straight back into gas, leaving behind what is known as the residual polar cap. The mystery was that while the winter cap is symmetrical about the south pole, the residual cap was offset, and scientists couldn't figure out why."

An anonymous reader writes "The Washington Post reports that the US Congress is funding laser weapons for use in the near future. Low-power lasers called 'dazzlers' are already being used in Iraq to temporarily reduce a person's vision. High-power laser weapons would allow precision attacks that minimize civilian casualties. From the Post: 'The science board said tactical laser systems could be developed for broader use because they "enable precision ground attack to minimize collateral damage in urban conflicts." The report suggested, for example, that "future gunships could provide extended precision lethality and sensing." The board also proposed using lasers to protect against rockets, artillery, mortars and unmanned airborne vehicles by blasting them out of the sky. Last month, the Army awarded Boeing $36 million to continue development of a high-energy laser mounted on a truck that could hit overhead targets. But deployment is not expected until 2016, even if all goes well.'"

Frequent Slashdot Contributor Bennett Haselton writes "A federal judge has ruled that a school district didn't violate a student's free speech rights when it suspended her for a parody MySpace page she created calling her principal a sex addict who "hits on students". In the ruling, Judge James M. Munley made the curious argument that if the case involves a student publishing lewd and offensive speech outside of school on their own time, then the proper precedent-setting cases to look to, are cases involving students making offensive statements in school during school hours, not cases involving students making less-offensive statements outside of school on their own time. In other words, if you can't find prior caselaw where all of the factors are the same, then the lewd-speech issue is more significant than the issue of whether the speech was made in or out of school."

method9455 writes "Barack Obama has edited his official website on many issues, including a huge revision on the technology page. Strangely it seems net neutrality is no longer as important as it was a few months ago, and the swaths of detail have been removed and replaced with fairly vague rhetoric. Many technologists were alarmed with the choice of Joe Biden before, and now it appears their fears might have been well founded." Update: 09/22 18:07 GMT by T : Julian Sanchez of Ars Technica passed on a statement from an Obama campaign representative who points out that the changes in wording highlighted by Versionista aren't the whole story, and that more Obama tech-plan details are now available in a PDF, saying "there is absolutely no substantive change to our policy - folks who want more information can click to get our full plan."
