An anonymous reader writes "Micro-blogging site Twitter is opposing an order from a US court to reveal the account details of supporters of WikiLeaks. Twitter has called on Facebook and Google to reveal whether they also received similar court orders. As part of the US government's investigation into WikiLeaks, a court ordered Twitter, in mid-December, to give details of accounts owned by supporters of the whistle-blower site. Twitter has protested against the subpoena and informed the individuals whose account information has been requested, while raising the possibility that other social networking players have received similar orders."

matsh sends word that PayPal has frozen the assets of wikileaks.org. From their Web site: "Paypal has as of 23rd of January 2010 frozen WikiLeaks assets. This is the second time that this happens. The last time we struggled for more than half a year to resolve this issue. By working with the respected and recognized German foundation Wau Holland Stiftung we tried to avoid this from happening again — apparently without avail." The submitter adds: "Hopefully we can pressure PayPal to resolve this quickly, since this seems like a dangerous political decision."

westtxfun writes "The Mars Express Orbiter captured a very cool movie of Phobos and Deimos on Nov 5. Besides the 'wow factor,' the images will be used to refine models of the moons' orbits. The orbiter has also captured high resolution images of Phobos back in July. 'The images were acquired with the Super Resolution Channel (SRC) of the High Resolution Stereo Camera (HRSC). The camera took 130 images of the moons on 5 November at 9:14 CET in a span of 1.5 minutes at intervals of 1s, speeding up to 0.5-s intervals toward the end. The image resolution is 110 m/pixel for Phobos and 240 m/pixel for Deimos — Deimos was more than twice as far from the camera. '"

Following our recent discussions about the growing evidence pointing to possible life on Mars, reader skywatcher2501 writes with news of a study that has ruled out one possible explanation for the levels of methane seen on that planet — that it might be replenished by disintegrating meteors entering the atmosphere. So two theories remain: either the gas is created as a by-product of reactions between volcanic rock and water, or it is a by-product of a lifeform's metabolism.

You know how, if you want to read a paywalled newspaper article, you can just paste its title into Google News and get a free pass? Those days may be coming to an end. Reader Captian Spazzz writes: "It looks like Google may be bowing to pressure from folks like News Corp.'s Rupert Murdoch. What I don't understand is what prevents the websites themselves from enforcing some limit. Why make Google do it?" (Danny Sullivan explains how they could do that.) "Newspaper publishers will now be able to set a limit on the number of free news articles people can read through Google, the company has announced. The concession follows claims from some media companies that the search engine is profiting from online news pages. Publishers will join a First Click Free programme that will prevent web surfers from having unrestricted access. Users who click on more than five articles in a day may be routed to payment or registration pages."
