Return to "Download Files" Page You are welcome to download the following graphic image of the Tree of Life for non-commercial, educational purposes: Tree of Life (~3,000 species, based on rRNA sequences) (pdf, 368 KB) (see Science, 2003, 300:1692-1697) This file can be printed as a wall poster. Printing at least 54" wide is recommended. Tree of Life tattoo, courtesy of Clare D'Alberto, who is working on her Ph.D. in biology at the University of Melbourne. The organisms depicted in this tattoo are (starting at 4 o'clock and going around clockwise): (1) a cyanobacterium (Anabaena); (2) a radiolarian (Acantharea); (3) a dinoflagellate (Ceratium); (4) an angiosperm (Spider Orchid); (5) a couple species of fungi (Penicillium and a yeast); (6) a ctenophore (comb jelly); (7) a mollusc (nudibranch); (8) an echinoderm (brittle star); and (9) a vertebrate (Weedy Sea Dragon). Here is another great Tree of Life tattoo! Cover of Molecular Systmatics, 2nd ed

The 6 Most Gigantic Everything in the History of War In the words of Mahatma Gandhi, "War makes people act like dicks." We don't want to glorify war or otherwise portray it as something other than terrible. Yet, war makes people think big, and sometimes you have to sit back and be amazed by what humans can accomplish when they really, really want to kill each other. The Big Gun: The Schwerer Gustav The Gustav is the biggest gun ever fired in combat, period.

What Is Science? From Feynman to Sagan to Asimov to Curie, an Omnibus of Definitions by Maria Popova “The most beautiful experience we can have is the mysterious — the fundamental emotion which stands at the cradle of true art and true science.” “We live in a society absolutely dependent on science and technology,” Carl Sagan famously quipped in 1994, “and yet have cleverly arranged things so that almost no one understands science and technology. That’s a clear prescription for disaster.” 10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?

Darwin's Tree of Life The drawing above is his original sketch of the tree, which was found in a notebook called ‘red transmutation notebook B’. Darwin later made his theory of evolution public, in his book On the Origin of Species. It included his illustration of the Tree of Life. The tips of the branches show the species that are still alive today, but the tree also shows all the species that have existed in the past but are now extinct. Darwin explained: Greek Gods Family Tree / Genealogy Doing homework? Your teacher has already seen this. See Theoi; it has properly-sourced information. Known errors: Generally inconsistent sourcing. This chart was made in 2004, and Wikipedia was treated as a primary source.

Pairs of charged particles produced when two beams of protons collide seem to be associated with each other even after they fly apart. “It is a small effect, but it is very interesting in itself,” said physicist Guido Tonelli, spokesperson for the LHC’s CMS experiment. Tonelli and colleagues announced the results in a seminar at CERN September 21 and in a paper submitted to the Journal of High Energy Physics. The LHC finally got up and running in March after more than a year of false starts.

Why are past, present, and future our only options? But things get awkward if you have a friend. (Use your imagination if necessary.) Low blow, Dr. Scientists discover beautiful new insect species after stumbling upon photos on Flickr Adult green lacewing (Semachrysa jade sp. n.). Photo by Hock Ping Guek Scientists have discovered a previously unknown species of lacewing insect after stumbling upon a series of photos posted on Flickr®, according to a paper published in the journal ZooKeys. The species is named Semachrysa jade and lives in the rainforests of Malaysia. Shaun Winterton, a researcher with the California State Collection of Arthropods at the California Department of Food & Agriculture, first found evidence of the species when he randomly stumbled upon a set of photos posted by Hock Ping Guek, a Malaysian photographer. Winterton recognized the insect as a potentially new species, but needed to collect field specimen in order to formally describe it.

Graphs Of Wikipedia: Influential Thinkers The internet is big — very big. One such way to investigate all of this free online content is through graphs. The network visualisations by Simon Raper in his fantastic post about graphing the history of philosophy is one example of how to exploit such data. Let’s take this a step further and create a series of graphs using everyone on Wikipedia.

We've recreated this hell, and it's not just hot, it is also very, very strange, says Amanda Gefter ( science writer based in London).

This tree is from an analysis of small subunit rRNA sequences sampled from about 3,000 species from throughout the Tree of Life. The species were chosen based on their availability, but we attempted to include most of the major groups, sampled very roughly in proportion to the number of known species in each group (although many groups remain over- or under-represented). by hellequin Aug 16
