The Sun Unleashes Coronal Mass Ejection At Earth 220

Posted by Soulskill from the return-fire dept.
astroengine writes "Yesterday morning, at 08:55 UT, NASA's Solar Dynamics Observatory detected a C3-class flare erupt inside a sunspot cluster. 100,000 kilometers away, deep within the solar atmosphere (the corona), an extended magnetic field filled with cool plasma forming a dark ribbon across the face of the sun (a feature known as a 'filament') erupted at the exact same time. It seems very likely that both eruptions were connected after a powerful shock wave produced by the flare destabilized the filament, causing the eruption. A second solar observatory, the Solar and Heliospheric Observatory, then spotted a huge coronal mass ejection blast into space, straight in the direction of Earth. Solar physicists have calculated that this magnetic bubble filled with energetic particles should hit Earth on August 3, so look out for some intense aurorae — a solar storm is coming."

New Xbox 360 S Uses Less Power, Makes Less Noise 176

Posted by Soulskill from the slices-dices-etc dept.
Vigile writes "Microsoft unveiled a new Xbox 360 S console at E3 this month, and without delay the new machine has been dissected and tested. The most dramatic change is the move to a single-chip CPU/GPU hybrid processor that is apparently being built on the 45nm process technology from GlobalFoundries, AMD's spun-off production facilities. With the inclusion of the new processor, the Xbox 360 S uses much less power (about 30-40%) compared to previous generation machines, and also turns out to be much quieter as a result of a single, larger fan. This article has photographic evidence of the teardown, with comparisons between this Valhalla platform and the older Falcon system, along with videos of the reconstruction process and noise comparisons." The new console also takes measures to protect itself from overheating, so RRoDs shouldn't be a problem with this revision.

Aral Sea May Recover; Dead Sea Needs a Lifeline 131

Posted by timothy from the just-needs-feng-shui-adjustment dept.
An anonymous reader writes "It's a tale of two seas. The drying up of the Aral Sea is considered one of the greatest environmental catastrophes in history, but the northern sector of the sea, at least, is showing signs of life. A dam completed in 2005 has increased the North Aral's span by 20 percent, and birds, fish, and people are all returning to the area. Meanwhile, the Dead Sea is still in the midst of precipitous decline, since too much water is being drawn out of the Jordan River for thirsty populations and crops. To keep the sea from shrinking more, scientists are pushing an ambitious scheme called the 'Red-Dead conduit,' which would channel huge amounts of water from the Red Sea to the Dead Sea. However, the environmental consequences of such a project may be troubling."

NHS Should Stop Funding Homeopathy, Says Parliamentary Committee 507

Posted by samzenpus from the how-am-I-going-to-align-my-chakras-now dept.
An anonymous reader writes "Homeopathic remedies work no better than placebos, and so should no longer be paid for by the UK National Health Service, a committee of British members of parliament has concluded. In preparing its report, the committee, which scrutinizes the evidence behind government policies, took evidence from scientists and homeopaths, and reviewed numerous reports and scientific investigations into homeopathy. It found no evidence that such treatments work beyond providing a placebo effect." Updated 201025 19:40 GMT by timothy: This recommendation has some people up in arms.
