As most of you are aware, we had a crash to forums and were down for over two days a while back. We did have to do an upgrade to the vbulletin software to fix the forums and that has created changes, VB no longer provide the hybrid or threaded forums. There are some issues/changes to the forums we are not able to fix or change. Also note the link address change, please let friends and posters know of the changed link to the forums. For now this is the only link available, https://forums.carm.org/vb5/ but if clicking on forum on carm.org homepage it will now send you to this link. (edited to add https: now working.

Again, we are working through some of the posting and viewing issues to learn how to post with the changes, you will have to check and test the different features, icons that have changed. You may also want to go to profile settings,since many of the notifications, information in profile, also to update/edit your avatar by clicking on avatar space, pull down arrow next to login for user settings.

Edit to add "How to read forums, to make it easier."
Pull down arrow next to login name upper right select profile, or user settings when page opens to profile,select link in tab that says Account. Then select/choose options, go down to Conversation Detail Options, Select Display mode Posts, NOT Activity, that selection of Posts will make the pages of discussions go to last post on last page rather than out of order that happens if you choose activity threads. Then be sure to go to bottom and select SAVE Changes in your profile options. You can then follow discussions by going through the pages, to the last page having latest responses. Then click on the other links Privacy, Notifications, to select viewing options,the forums get easier if you open all the tabs or links in your profile, user settings and select options. To join Super Member, pull down arrow next to login name, select User Settings and then click on tab/link at top that says Subscriptions.

Thank you for your patience and God Bless.

  • Dr. Jame Tour on prebiotic Chemestry

    Dr. Tour is one of the world’s top synthetic organic chemists. He has authored 680 scientific publications and holds more than 120 patents (here is a partial list). In 2014, Thomson Reuters named him one of “The World’s Most Influential Scientific Minds,” and in 2018 Clarivate Analytics recognized him as one of the world’s most highly cited researchers. - Di institute

    The world’s best synthetic chemists, biochemists, and evolutionary biologists have combined forces to form a team—a dream team in two quite distinct senses of the word. Money is no object. They have at their disposal the most advanced analytical facilities, the complete scientific literature, synthetic and natural coupling agents, and all the reagents their hearts might desire. Carbohydrates, lipids, amino acids, and nucleic acids are stored in their laboratories in a state of 100% enantiomeric purity.

    Would the dream team—please—assemble a living system?

    Take your time, folks, take a few billion years.

    Nothing? Well, well, well.

    Let us assume that all the building blocks of life, and not just their precursors, have been made to a high degrees of purity, including homochirality where applicable—the carbohydrates, the amino acids, the nucleic acids, and the lipids. They are stored in cool caves, away from sunlight, and away from oxygen. These molecules are indifferent to environmental degradation.

    And let us further assume that they are all stored in one comfortable corner of the earth, not separated by thousands of kilometers or on different planets.

    And that they all exist not just in the same square kilometer, but in neighboring pools where they can conveniently and somehow selectively mix with each other as needed.

    Now what? How does the dream team assemble them without enzymes?

    Very well. Give the dream team polymerized forms: polypeptides, all the enzymes they desire, the polysaccharides, DNA and RNA in any sequence, cleanly assembled.

    Ready now?

    Apparently not.

    We teach our students that when a mechanism does not support their observations, the mechanism must either be revised to support the facts or entirely discounted. They are not required to provide an alternative.

    We are such stuff as dreams are made on. It has a ring among prebiotic chemists.
    The Current State

    Those who think scientists understand the issues of prebiotic chemistry are wholly misinformed. Nobody understands them. Maybe one day we will. But that day is far from today. It would be far more helpful (and hopeful) to expose students to the massive gaps in our understanding. They may find a firmer—and possibly a radically different—scientific theory.

    The basis upon which we as scientists are relying is so shaky that we must openly state the situation for what it is: it is a mystery.

      Well apparently that makes him a "Chemest", on the other hand, the science in question is "Chemistry".
      As Saint Mark Twain put it "God created Man in His own image. And man has been returning the favor ever since."
