Outer Space Flight Videos & Pictures. Nasa posts thousands of amazing space images on the internet. By Ted Thornhill Updated: 08:33 GMT, 18 April 2011 You'll go starry-eyed at Nasa’s latest mission success - because the space agency has uploaded thousands of amazing space snaps onto the internet, including shots of previously unseen galaxies, stars and asteroids.
The colossal gallery – available to anyone with a connection to the web - was taken by Nasa’s super hi-tech sky-mapping telescope. It took a staggering two and a half million pictures of the universe, which include 33,000 new asteroids found floating between Mars and Jupiter – and 20 comets. Heavens above: This WISE image shows the Berkeley 59 cluster of stars, which are relative babies at just a few million years old, and resemble a cosmic rose Since 2009 the £200million infrared telescope, called the Wide-field Infrared Survey Explorer, or WISE, has been scanning the cosmos with the most sophisticated cameras ever deployed in space.

Red Gold . Blood Journey . Phase 1. Blood is a mixture of cells and a watery liquid, called plasma, that the cells float in.
It also contains other things like nutrients (such as sugar), hormones, clotting agents, and waste products to be flushed out of the body. There are three kinds of cells in the blood: red blood cells, white blood cells, and platelets. Red blood cells carry oxygen from the lungs throughout the body, white blood cells help fight infection, and platelets help in clotting.
Red blood cells (also called erythrocytes) are the most numerous, making up 40-45 percent of one's blood, and they give blood its characteristic color. Red blood cells are shaped like tiny doughnuts, with an indentation in the center instead of a hole. White blood cells (leukocytes) are the body's mobile warriors in the battle against infection and invasion. Lymphocytes are key parts of the body's immune system. The blood cells called platelets (thrombocytes) help blood to clot, in several different ways. Richard Dawkins Explains Origins of Homosexuality - a video. SKY-MAP.ORG. Stellar Wormholes May Exist. Hidden Portals in Earth's Magnetic Field. The four identical spacecraft of NASA’s Magnetospheric Multiscale, or MMS, mission (one of which is illustrated here) fly through the boundaries of Earth’s magnetic field to study an explosive process of magnetic reconnection.
Thought to be the driver behind everything from solar flares to aurora, magnetic reconnection creates a sudden reconfiguration of magnetic fields, releasing huge amounts of energy in the process. Credits: NASA's Goddard Space Flight Center The explosive realignment of magnetic fields — known as magnetic reconnection — is a thought to be a common process at the boundaries of Earth’s magnetic bubble. Magnetic reconnection can connect Earth’s magnetic field to the interplanetary magnetic field carried by the solar wind or coronal mass ejections.

You are what your father ate: Paternal diet affects lipid metabolizing genes in offspring - - - Physorg.com.
By - - PHYSORG.COM Added: Friday, 24 December 2010 at 5:44 AM Scientists at the University of Massachusetts Medical School and the University of Texas at Austin have uncovered evidence that environmental influences experienced by a father can be passed down to the next generation, "reprogramming" how genes function in offspring.
A new study published this week in Cell shows that environmental cues—in this case, diet—influence genes in mammals from one generation to the next, evidence that until now has been sparse. These insights, coupled with previous human epidemiological studies, suggest that paternal environmental effects may play a more important role in complex diseases such as diabetes and heart disease than previously believed. "Knowing what your parents were doing before you were conceived is turning out to be important in determining what disease risk factors you may be carrying," said Oliver J.

Lesch–Nyhan syndrome. Lesch–Nyhan syndrome (LNS), also known as Nyhan's syndrome, Kelley-Seegmiller syndrome and juvenile gout,[1] is a rare inherited disorder caused by a deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HGPRT), produced by mutations in the HPRT gene located on the X chromosome.
LNS affects about one in 380,000 live births.[2] The disorder was first recognized and clinically characterized by medical student Michael Lesch and his mentor, pediatrician William Nyhan, who published their findings in 1964.[3] The HGPRT deficiency causes a build-up of uric acid in all body fluids. This results in both hyperuricemia and hyperuricosuria, associated with severe gout and kidney problems. Neurological signs include poor muscle control and moderate intellectual disability. These complications usually appear in the first year of life.

A sad day for personal genomics : Genetic Future. (Cross-posted to Genomes Unzipped.)
Today’s US Congress Committee on Energy and Commerce hearing into the direct-to-consumer genetic testing industry was a vicious affair. Representatives from testing companies 23andMe, Navigenics and Pathway faced a barrage of questions about the accuracy and utility of their tests, made all the worse by the fact that many of the Committee’s members seemed unable to distinguish between the more responsible companies in the field and the scammers and bottom-feeders.

After years of painstaking research and experimentation, genomic pioneer J. Craig Venter has accomplished a long-awaited goal: he and his team at the J. Craig Venter Institute have introduced a synthetic genome into bacterial cells that can grow and replicate itself.
Some have gone as far as calling this engineered bacterium a new form of artificial life, though Venter has opted for the term “synthetic cell.” When DNA means do not ask - Times Online. 12 Events That Will Change Everything, Made Interactive: Scienti. Carbon Atom 1.
