'Quadruple helix' DNA seen in human cells
20 January 2013Last updated at 14:19 ET By Jonathan Amos Science correspondent, BBC News A representation of the four-stranded structure (L) with fluorescent markers revealing its presence inside cells (R) Cambridge University scientists say they have seen four-stranded DNA at work in human cells for the first time. The famous "molecule of life", which carries our genetic code, is more familiar to us as a double helix. But researchers tell the journal Nature Chemistry that the "quadruple helix" is also present in our cells, and in ways that might possibly relate to cancer. They suggest that control of the structures could provide novel ways to fight the disease. "The existence of these structures may be loaded when the cell has a certain genotype or a certain dysfunctional state," said Prof Shankar Balasubramanian from Cambridge's department of chemistry.

Ο ΑΦΥΠΝΙΣΤΗΣ: ΤΑ ΡΥΠΑΡΑ ΓΕΝΗ ΤΩΝ ΝΕΦΕΛΙΜ ΦΑΤΣΑ-ΚΑΡΤΑ ΣΤΟ ΚΕΝΤΡΟ ΤΟΥ HOLLYWOOD!
Από αναγνώστη μας που βρίσκεται αυτές τις μέρες στην Αμερική, λάβαμε και δημοσιεύουμε τις παρακάτω φωτογραφίες που παρουσιάζουν σύγχρονες απεικονίσεις γιγαντιαίου μεγέθους (μάλλον φυσικού μεγέθους για τα "πρόσωπα" που εικονίζουν) των γνωστών "λαμόγιων" Νεφελίμ. Εδώ, "κοσμούν" τον εξωτερικό περίγυρο του εμπορικού συγκροτήματος "Hollywood & Highland" Mall στο Hollywood! Για μας, αυτό αποτελεί "αμοιβή" για τα όσα τόσο καιρό "ευαγγελιζόμαστε". Δείγμα ότι αυτά που λέγονται τόσο εδώ όσο και αλλού, τελικά πιάνουν "τόπο" και αρχίσαμε να συνεννοούμαστε... enjoy!!! κάντε κλικ πάνω στις φωτό για μεγέθυνση Και μιας και είδατε τις φωτογραφίες, ας ξαναδούμε και δυο πράγματα για τα αρχαία αυτά λαμόγια (που λέει και ο Δημοσθένης...) Οι Νεφελίμ όπως μας πληροφορούν αρχαία κείμενα ήταν (και είναι) μια φυλή γιγάντων που προέκυψε απ' τη σεξουαλική ένωση έκπτωτων αγγέλων (Ελοχίμ) με τις "κόρες των ανθρώπων". Όλα αυτά συνέβαιναν ώσπου γεννήθηκε ο Δίας.

My 'Naked' Truth | Robin Korth
Naked, I stood at the closet doors with the lights on and made myself ready. I took a deep breath and positioned the mirrors so I could see all of me. I consciously worked to remove my self-believed inner image. I opened my eyes and looked very carefully at my body. And my heart lurched at the truth: I am not a young woman anymore. I am a woman well-lived. I am a 59-year-old woman in great health and in good physical shape. Why this brutal scrutiny of myself? We met on a dating site. On Monday evening over the phone, I asked this man who had shared my bed for three nights running why we had not made love. I was stunned. We talked for some time more, my head reeling at the content of the conversation. He explained that now that I knew what was required, we could have a great time in the bedroom. When I told Dave that I never wanted to see or hear from him again, he was confused and complained that I was making a big deal out of nothing. Robin Korth enjoys interactions with her readers.
Looking At Tears Under A Microscope Reveals A Shocking Fact.
Share on Facebook One day Rose-Lynn Fisher wondered if her tears of grief would look different from her tears of joy, so she began to explore them up close under a microscope. She studied 100 different tears and found that basal tears (the ones that our body produces to lubricate our eyes) are drastically different from the tears that happen when we are chopping onions. The tears that come about from hard laughter aren’t even close to the tears of sorrow. Like a drop of ocean water each tiny tear drop carries a microcosm of human experience. Her project is called The Topography of Tears. Tears from laughing until crying Rose-Lynn Fisher Tears of change Tears of grief Tears from onions Joseph Stromberg of the Smithsonian’s Collage of Arts and Sciences explained that there are three major types of tears: basal, reflex, and psychic (triggered by emotions). Basal tears Tears of timeless reunion Tears of ending and beginning Tears of momentum, redirected Tears of release Tears of possibility and hope

Fulfilling a dream. -- Indiegogo
Hello Dearest contributors, My name is Gabriel Alemany. I am a 16 year old teenager who has a hunger to discover and explore the many places this world has to offer. While there are many campaigns on this webpage I'd love it if you could hear mine :) during the begining of this year I met a wonderful german girl, A girl that made me laugh and enjoy so many things about life, this is the story.As months past I kept falling in love with this girl and in such a short time I came to share every single day with her. Sadly... her mother is a diplomat who had been relocated to germany, We agreed however that this was going to be a see you later rather than a goodbye. I know its the silliest of the requests anyone could ever ask but If I manage to save at least 900 euro by the end of september I will be able to visit her and visit Germany! During my short lived life I have tried to do the best I can, be the best person I can be and feel happy for as many people as I could. A los Dominicanos
