Submission + - Pluto Probe Makes Discoveries at Jupiter (jhuapl.edu)

Riding with Robots writes: No, it's not an accident due to a metric-to-English-units error. In February, the New Horizons probe passed through the Jupiter system on its way to Pluto, and we saw some spectacular pictures. Now, the science teams have published detailed scientific results, along with new images and movies. an overview is now online. The probe's instruments saw clouds form from ammonia welling up from Jupiter's lower atmosphere, and heat-induced lighting strikes in the polar regions, and fresh eruptions on the volcanic moon Io. New Horizons also captured the clearest images ever of the tenuous Jovian ring system, where scientists spotted clumps of debris that may indicate a recent impact inside the rings, or some more exotic phenomenon.

Submission + - A campaign to block Firefox users (whyfirefoxisblocked.com) 5

rarwes writes: A website is aiming at blocking Firefox users. This because a fraction of the Firefox users installed an Ad Blocker and thus stealing money from website owners that use ads. They recommend using IE, Opera or IE tab. From the site: Demographics have shown that not only are FireFox users a somewhat small percentage of the internet, they actually are even smaller in terms of online spending, therefore blocking FireFox seems to have only minimal financial drawbacks, whereas ending resource theft has tremendous financial rewards for honest, hard-working website owners and developers.

Submission + - Scientists discover how to erase memories (pressesc.com) 1

amigoro writes: "Neuroscientists have discovered that long-term memories are not etched in a "clay tablet"-like stable form as once thought, but the process is much more dynamic, involving a miniature molecular machine that must run constantly to keep memories going, jamming the machine briefly can erase long-term memories."

Submission + - Orwellian 'Behavior Detection Officers' for TSA (msn.com) 1

Stanistani writes: "According to Newsweek, at US airports some security personnel will be observing passengers for facial expressions which indicate malicious intent. If they believe you look like you might be thinking of causing harm, you can be taken aside for further questioning. Welcome these new overseers: 'Behavior Detection Officers.' Their potentially life-changing decisions will be based on the pseudoscience of 'micro-expressions.'"
