&lt;p&gt;Primatology Lesson of the Day #12:&lt;/p&gt;
&lt;p&gt;Gigantopithecus is an extinct genus of ape that lived in the jungles of China, India, and Vietnam until about 100 thousand years ago. Its closest relative is the orangutan and for that reason is thought to have had a red coat of hair. Gigantopithecus was the largest ape to ever live. The males measured in at almost 10 feet and 1200 pounds with armspans of over 12 feet. That’s over twice as large as a big silverback gorilla. Walking on all fours it’d be about the size of a Volkswagen Bug. Despite their intimidating size, remains of their teeth suggest they ate mostly fruit and bamboo. A full grown gigantopithecus had no predator to fear, but humans and other predators are thought to have hunted the young or weak. &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;CentraSight &lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;An elderly woman is the first to have a small telescopic pupil to aid her sight - via &lt;a href="http://www.denverpost.com/news/ci_21098064/new-surgery-turns-colorado-womans-damaged-eye-into" title="http://www.denverpost.com/news/ci_21098064/new-surgery-turns-colorado-womans-damaged-eye-into"&gt;Denver Post&lt;/a&gt;:&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;Doris Ekblad-Olson is not too old to feel childish wonder at the idea of fixing her ailing eyes by letting someone suture in a tiny telescope.&lt;/p&gt;
&lt;p&gt;But age does allow her to be blunt about her anxiety as the first Colorado patient to have the pea-size telescope placed in her right eyeball.&lt;/p&gt;
&lt;p&gt;“I would rather I was his 100th patient,” chuckles Ekblad-Olson, 82, as she discusses the surgery with ophthalmologist Dr. Starck Johnson.&lt;/p&gt;
&lt;p&gt;The former teacher was still game to be the Colorado guinea pig, though, and went under Johnson’s micro-knives at Sky Ridge Medical Center on Tuesday. Doctor and patient hope the &lt;span&gt;successfully implanted telescope will bring vision back to eyes dimmed by a severe form of macular degeneration.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;“There hasn’t been a lot we can do for these patients,” Johnson said. “We’ve been waiting a long time for this to come to fruition.”&lt;/p&gt;

&lt;p class="MsoNormal"&gt;&lt;span&gt;Lactose intolerance is the inability to digest and absorb lactose (the sugar in milk) that results in gastrointestinal symptoms when milk or food products containing milk are consumed.&lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;strong&gt;&lt;span&gt;What causes lactose intolerance?&lt;/span&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;span&gt;Lactose is a large sugar molecule that is made up of two smaller sugars, glucose and galactose. In order for lactose to be absorbed from the intestine and into the body, it must first be split into glucose and galactose. The glucose and galactose are then absorbed by the cells lining the small intestine. The enzyme that splits lactose into glucose and galactose is called lactase, and it is located on the surface of the cells lining the small intestine. &lt;/span&gt;&lt;/p&gt;
&lt;p class="MsoNormal"&gt;&lt;span&gt;Lactose intolerance is caused by reduced or absent activity of lactase that prevents the splitting of lactose (lactase deficiency). Lactase deficiency may occur for one of three reasons, congenital, secondary or developmental.&lt;/span&gt;&lt;/p&gt;

After a series of test maneuvers inside and above Challenger’s payload bay, McCandless &lt;strong&gt;went “free-flying” to a distance of 320 feet away from the Orbiter&lt;/strong&gt;.

However, those materials can pose safety risks and are difficult to target, says Daniel Anderson, an associate professor of health sciences and technology and chemical engineering.&lt;br/&gt;&lt;br/&gt;Read more: &lt;a href="http://www.laboratoryequipment.com/news-Snippets-of-RNA-Could-Fight-Tumors-060512.aspx"&gt;&lt;a href="http://www.laboratoryequipment.com/news-Snippets-of-RNA-Could-Fight-Tumors-060512.aspx"&gt;http://www.laboratoryequipment.com/news-Snippets-of-RNA-Could-Fight-Tumors-060512.aspx&lt;/a&gt;&lt;/a&gt;&lt;/p&gt;</description><link>http://lancelafontaine.tumblr.com/post/24610598676</link><guid>http://lancelafontaine.tumblr.com/post/24610598676</guid><pubDate>Thu, 07 Jun 2012 10:55:13 -0400</pubDate></item><item><title>Milky Way Galaxy Doomed: Collision with Andromeda...</title><description>&lt;img src="http://25.media.tumblr.com/tumblr_m52wm5IS6e1qbn5m1o1_500.jpg"/&gt;&lt;br/&gt;&lt;br/&gt;&lt;p&gt;&lt;big&gt;&lt;strong&gt;Milky Way Galaxy Doomed: Collision with Andromeda Pending&lt;/strong&gt;&lt;/big&gt;&lt;/p&gt;

&lt;p&gt;&lt;small&gt;&lt;strong&gt;Will our Milky Way Galaxy collide one day with its larger neighbor, the Andromeda Galaxy?&lt;/strong&gt;&lt;/small&gt;&lt;/p&gt;
&lt;p&gt;&lt;small&gt;Most likely, yes. &lt;a href="http://adsabs.harvard.edu/abs/2012arXiv1205.6863S"&gt;Careful plotting&lt;/a&gt; of slight displacements of M31’s stars relative to background galaxies on recent Hubble Space Telescope images indicate that the center of M31 could be on a direct &lt;a href="http://science.nasa.gov/science-news/science-at-nasa/2012/31may_andromeda/"&gt;collision course&lt;/a&gt; with the center of our home galaxy.&lt;/small&gt;&lt;/p&gt;
&lt;p&gt;&lt;small&gt;Still, the errors in sideways velocity appear sufficiently large to admit a good chance that the central parts of the two galaxies will miss, slightly, but will become close enough for their outer halos to become &lt;a href="http://4.bp.blogspot.com/_2fy2gotuh00/SgRcixI-rwI/AAAAAAAABcI/52z1tYRX5dg/s400/cats+entangled.jpg"&gt;gravitationally entangled&lt;/a&gt;. Once that happens, the two galaxies will become bound, &lt;a href="http://hubblesite.org/newscenter/archive/releases/2012/20/video/a/"&gt;dance around&lt;/a&gt;, and &lt;a href="http://adsabs.harvard.edu/abs/2012arXiv1205.6865V"&gt;eventually merge&lt;/a&gt; to &lt;a href="http://hubblesite.org/newscenter/archive/releases/2012/20/image/b/format/web_print/"&gt;become one&lt;/a&gt; large elliptical galaxy — over the next few billion years.&lt;/small&gt;&lt;/p&gt;
&lt;p&gt;&lt;small&gt;Pictured above is an artist’s illustration of the sky of a world in the distant future when the central parts of each galaxy begin to destroy each other. The exact future of our Milky Way and the entire surrounding &lt;a href="http://en.wikipedia.org/wiki/Local_group_of_galaxies"&gt;Local Group of Galaxies&lt;/a&gt; is likely to remain an active topic of research for years to come.&lt;/small&gt;&lt;/p&gt;</description><link>http://lancelafontaine.tumblr.com/post/24610191159</link><guid>http://lancelafontaine.tumblr.com/post/24610191159</guid><pubDate>Thu, 07 Jun 2012 10:45:34 -0400</pubDate></item><item><title>M17

&lt;p&gt;The types of quarks inside the neutron are called up and down quarks. The difference between them is in the mass and in the charge. The up quark has a charge +2/3 and the down quark (-1/3).&lt;/p&gt;
&lt;p&gt;The neutron is electricly neutral (which is the reason for its name), so its total charge is 0. Threfore to only way for it to have a zero total charge is when it is build of one Up quark and two Dawn quarks. &lt;/p&gt;
&lt;p&gt;Up + Down + Down = Neutron;&lt;br/&gt;2/3 - 1/3 - 1/3 = 0 &lt;/p&gt;
&lt;p&gt;Protons have three quarks too. Protons have charge +1, therefore&lt;/p&gt;
&lt;p&gt;Up + Up + Down = Proton &lt;/p&gt;

&lt;blockquote&gt;&lt;p&gt;Fascinating and complicated: Lignin&lt;/p&gt;
&lt;p&gt;(C&lt;sub&gt;9&lt;/sub&gt;H&lt;sub&gt;10&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt;, C&lt;sub&gt;10&lt;/sub&gt;H&lt;sub&gt;12&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;, C&lt;sub&gt;11&lt;/sub&gt;H&lt;sub&gt;14&lt;/sub&gt;O&lt;sub&gt;4&lt;/sub&gt;) &lt;/p&gt;
&lt;p&gt;Lignin or lignen is a complex chemical compound most commonly derived from wood, and an integral part of the secondary cell walls of plants and some algae. It is one of the most abundant organic polymers on Earth, exceeded only by cellulose, employing 30% of non-fossil organic carbon, and constituting from a quarter to a third of the dry mass of wood.  &lt;/p&gt;&lt;/blockquote&gt;</description><link>http://lancelafontaine.tumblr.com/post/23393962441</link><guid>http://lancelafontaine.tumblr.com/post/23393962441</guid><pubDate>Sun, 20 May 2012 00:05:25 -0400</pubDate></item></channel></rss>
