The orbiter's six-member crew will deliver some 13 metric tons of parts to the station as NASA wraps up its final scheduled shuttle launches and seeks to complete construction of the station. After Atlantis 's mission, designated STS-129 , only five planned shuttle launches remain.

For instance, galaxies and galactic clusters behave as if they were far more massive than would be expected if they comprised only atoms and molecules, spinning faster than their observable mass would explain. What is more, the very presence of assemblages such as our Milky Way Galaxy speaks to the influence of more mass than we can see. If the mass of the universe were confined to atoms, the clumping of matter that allowed galaxies to take shape would never have transpired. <a href=http://www.scientificamerican.com/article.cfm?id=dark-matter-modified-gravity>[More]</a><br clear="both" style="clear: both;"/> <br clear="both" style="clear: both;"/> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:6e02d32070504a1e4f1bbeebbc6996ff:AOAV1KGWnflbC6a4yOmLMP0TwXfcEKvQ1yWHwoT%2BX3fmCpDmcyr0GerVdjAU5B%2BUAYBzPYwd2W5%2F'><img border='0' title='Add to digg' alt='Add to digg' src='http://images.pheedo.com/images/mm/digg.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:7a4524a51b4075d5b2d26e62ecea87ca:sYmldZnp1ngLY0y3u5CzWZRQY5vN4gbfUoBlxOLuQMFXhSTO8PhhHEPKqQUtRWGjLxnfCyTrNBGM1g%3D%3D'><img border='0' title='Add to StumbleUpon' alt='Add to StumbleUpon' src='http://images.pheedo.com/images/mm/stumbleit.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:6d7307f20ca15c65336e360acdb04e61:dHJKHNDjv%2BQLgan22fO3UQAYG51fe6WySdkg1sxTQCEP69v%2BcbFtZKFmB7ESnSi6ldBkIjNoWEg5'><img border='0' title='Add to Reddit' alt='Add to Reddit' src='http://images.pheedo.com/images/mm/reddit.png'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:bcde959dbde57973e90594978c3101c0:9h%2BboGGOCDcsO%2BlN6OhuJQCHgMKqGu23cD9LgsdILaI95Qe90tNjGxWI32rImvwp5kStjyoOknZMkQ%3D%3D'><img border='0' title='Add to Facebook' alt='Add to Facebook' src='http://images.pheedo.com/images/mm/facebook.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:7dcf1dbfe9ff62ab552ceb26349ab553:XF2hYs0RV5OVYJdC04AjFAjjGYP9nsX%2BtXi%2FMf5s5fqbeuz7xRlLAoFxO8HOtgU%2FI6ypj4nCVig5'><img border='0' title='Add to del.icio.us' alt='Add to del.icio.us' src='http://images.pheedo.com/images/mm/delicious.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:418dc67280643a4cf8fac75a09675419:%2Blx81gf%2B7MgVMK%2FjO9fBpzLGvM%2F39Ed%2Bk03jXgSgsqk0hlxJyLGLPMpTykyqmw096JhNH4d5nXCq'><img border='0' title='Email this Article' alt='Email this Article' src='http://images.pheedo.com/images/mm/emailthis.png'/></a> <br clear="both" style="clear: both;"/> <a href="http://ads.pheedo.com/click.phdo?s=a6cd77735d101ff6fede173bc593feb4&p=1"><img alt="" style="border: 0;" border="0" src="http://ads.pheedo.com/img.phdo?s=a6cd77735d101ff6fede173bc593feb4&p=1"/></a> <img alt="" height="0" width="0" border="0" style="display:none" src="http://a.rfihub.com/eus.gif?eui=2223"/> Physics,Space,Astrophysics,Cosmology Thu, 05 Nov 2009 08:00:00 EST http://rss.sciam.com/click.phdo?i=9f3ac5493186982a6b6e3226c4cfbce6 http://www.scientificamerican.com/article.cfm?id=will-e-t-look-like-us <p>What are the odds that intelligent, technically advanced aliens would look anything like the ones in films, with an emaciated torso and limbs, spindly fingers and a bulbous, bald head with large, almond-shaped eyes? What are the odds that they would even be humanoid? In a YouTube video, produced by Josh Timonen of the Richard Dawkins Foundation for Reason and Science, I argue that the chances are close to zero ( www.youtube.com/watch?v=JKAXrmkx12g ). Richard Dawkins himself made this interesting observation in a private communication after viewing it:</p><p> I would agree with [Shermer] in betting against aliens being bipedal primates, and I think the point is worth making, but I think he greatly overestimates the odds against. [University of Cambridge paleontologist] Simon Conway Morris, whose authority is not to be dismissed, thinks it positively likely that aliens would be, in effect, bipedal primates. [Harvard University biologist] Ed Wilson gave at least some time to the speculation that, if it had not been for the end-Cretaceous catastrophe, dinosaurs might have produced something like the attached [referring to paleontologist Dale A. Russell&rsquo;s illustrated evolutionary projection of how a bipedal dinosaur might have evolved into a reptilian humanoid]. </p> <a href=http://www.scientificamerican.com/article.cfm?id=will-e-t-look-like-us>[More]</a><br clear="both" style="clear: both;"/> <br clear="both" style="clear: both;"/> <a style='font-size: 10px;

Then you, too, could take advantage of the marvels of quantum mechanics, such as being in two places at once--very handy for juggling the competing demands of modern life. Alas, physicists have long spoiled the fantasy by saying that quantum mechanics applies only to microscopic things.</p><p>Yet that is a myth. In the modern view that has gained traction in the past decade, you don&rsquo;t see quantum effects in everyday life not because you are big, per se, but because those effects are camouflaged by their own sheer complexity. They are there if you know how to look, and physicists have been realizing that they show up in the macroscopic world more than they thought. &ldquo;The standard arguments may be too pessimistic as to the survival of quantum effects,&rdquo; says Nobel laureate physicist Anthony Leggett of the University of Illinois.</p> <a href=http://www.scientificamerican.com/article.cfm?id=easy-go-easy-come>[More]</a><br clear="both" style="clear: both;"/> <br clear="both" style="clear: both;"/> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:1ce4e46505a5c83da834369cf3e01b34:f%2FsfdUR9jWG8H9a84mGFNZvjWzoyJsgolutHM8m8ysA3AM4rJHXe%2BjpxxBmNfiUcXRkqXFQvYBOf'><img border='0' title='Add to digg' alt='Add to digg' src='http://images.pheedo.com/images/mm/digg.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:9602d53ee4d81cf3afe0ee281043604d:XoR8pJx3pznviDzCa9EIIdxgvNS4O0xHGXi8mOPQPN1oa9e5GaM9QY%2FuZX4IkIhOnPd%2Ba2tElcL6nA%3D%3D'><img border='0' title='Add to StumbleUpon' alt='Add to StumbleUpon' src='http://images.pheedo.com/images/mm/stumbleit.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:bf11dd030b9540a34e0091c4e379daa6:XMtVmUVUup5DmsPE8b%2BmHiOvVqBwjkEz8T6etMujdTBlZIk96KNk9qhNW0lEF4mEM1umvwTKl%2Fj2'><img border='0' title='Add to Reddit' alt='Add to Reddit' src='http://images.pheedo.com/images/mm/reddit.png'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:1f2c549dd974c5d0acdc5a032bd0e1ce:kj2tRJKZDk6M%2FxdW2STv7jwliw%2FigIUDzfAMphNRIqYVJZkwOaQWu3cKXrOgMhr4aHWdAa86Zk9YwQ%3D%3D'><img border='0' title='Add to Facebook' alt='Add to Facebook' src='http://images.pheedo.com/images/mm/facebook.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:3b1e6a3f2b1a2410a7c1e50b95009a16:zjFNpMds41e%2BrM6QCQM5plA0TuEtFPiLc%2FScINuvOR%2B0VWlkk%2FJRfc164dbGQi3RW6g0BfJVQep8'><img border='0' title='Add to del.icio.us' alt='Add to del.icio.us' src='http://images.pheedo.com/images/mm/delicious.gif'/></a> <a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:b6640b0613fd6562b0fb5b32088273c9:rV%2F6dsKdhuJYwktxDoFy%2FiRoYBjBGPXc%2F1n%2BecHKj%2Bvcl2bb6SdHMXssM3%2FvrMJT45bWuI3uPO1X'><img border='0' title='Email this Article' alt='Email this Article' src='http://images.pheedo.com/images/mm/emailthis.png'/></a> <br clear="both" style="clear: both;"/> <a href="http://ads.pheedo.com/click.phdo?s=93a226851472cb7f46eb0d9aed7b4949&p=1"><img alt="" style="border: 0;" border="0" src="http://ads.pheedo.com/img.phdo?s=93a226851472cb7f46eb0d9aed7b4949&p=1"/></a> <img alt="" height="0" width="0" border="0" style="display:none" src="http://a.rfihub.com/eus.gif?eui=2223"/> Chemistry,Environment,Physics,Space,Technology,Basic Science,Thought & Cognition,Energy Technology,Energy Technology Mon, 02 Nov 2009 08:00:00 EST http://rss.sciam.com/click.phdo?i=3653885b177c76dc88f796d5cd82e58b http://www.scientificamerican.com/article.cfm?id=the-long-lost-siblings-of-the-sun <p>People have often sought solitude in the starry night sky, and it is an appropriate place for that. The night is dark because, in cosmic terms, our sun and its family of planets are very lonely. Neighboring stars are so far away that they look like mere specks of light, and more distant stars blur together into a feeble glow. Our fastest space probes will take tens of thousands of years to cross the distance to the nearest star. Space isolates us like an ocean around a tiny island.</p><p>Yet not all stars are so secluded. About one in 10 belongs to a cluster, a swarm of hundreds to tens of thousands of stars with a diameter of a few light-years. In fact, most stars are born in such groups, which generally disperse over billions of years, their stars blending in with the rest of the galaxy. What about our sun? Might it, too, have come into existence in a star cluster? If so, our location in the galaxy was not always so desolate.
