'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.

Ironic? Spanked Children More Likely to Break the Law
By Rick Nauert PhD Senior News Editor Reviewed by John M. Grohol, Psy.D. on November 25, 2013 Spanking apparently can have an unintended effect from what a parent has in mind; in fact, just the opposite. Emerging research suggests university students who were spanked as children are more likely to engage in criminal behavior. University of New Hampshire’s Murray Straus, Ph.D., considered one of the foremost researchers on corporal punishment, also found that even young adults whose parents were generally loving and helpful as they were growing up, showed higher rates of criminal behavior. “The results show that spanking is associated with an increase in subsequent misbehavior, which is the opposite of what almost everyone believes. “These results are consistent with a large number of high quality peer-reviewed studies,” Straus said. Straus looked at criminality trends of university students in 15 countries using nine measures of criminality. Source: University of New Hampshire

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

Where You Find The Person You’re Going To Become
It began when I was small. My first out-of-body experiences happened very much within my body, while I stared at my little hand. I would hold it out in front of me until the background focus shifted away from my awareness and the colors somehow morphed in that odd and unexplainable way they do and I did my best not to blink because the more I could focus the higher I could get on this very idea that my name was Brianna. This hand belongs to this body, and this body belongs to this name, and this name is this collection of audible sounds. I spent a lot of time convincing myself I was who I was when I was a kid. It was my first shrieking moment of clarity. There are so many tortured things in a life. It’s so essential, and yet it’s always elusive. We’ve all but made “finding yourself” a necessity, a standard of human mental stability, when its very foundation is nothing but illusion (or, perhaps, delusion.) I spent my whole life defining and redefining who I was and who I should be.
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.
Art, science and schizophrenia - All In The Mind
Brendon Clarke: What I would be hearing in the auditory hallucinations would be knocking me down just with the most abusive torturous comments, to a point where I was feeling so vulnerable and so low, and then the voice would slip in with the suicide line, that David wanted me to kill myself. And that was the ongoing nature of the voice that I was hearing. There was actually no hope that things were going to get better and we are going back about 20 years, so we weren’t talking then about recovery or that things can get better. Lynne Malcolm: Schizophrenia. But the way schizophrenia is viewed has changed quite dramatically. Lynne Malcolm with you, and on All in the Mind today we’ll hear how scientists, clinicians and artists are now putting their heads together to improve the experience of those living with schizophrenia. [Applause] Thanks, Brendon, for joining us today. Brendon Clarke: Yes, certainly. Lynne Malcolm: And what about your family—were your family supportive then?
