Single dose of hallucinogen may create lasting personality change. Thursday, September 29, 2011 Psilocybn A single high dose of the hallucinogen psilocybin, the active ingredient in so-called "magic mushrooms," was enough to bring about a measureable personality change lasting at least a year in nearly 60 percent of the 51 participants in a new study, according to the Johns Hopkins researchers who conducted it.
Lasting change was found in the part of the personality known as openness, which includes traits related to imagination, aesthetics, feelings, abstract ideas and general broad-mindedness. Changes in these traits, measured on a widely used and scientifically validated personality inventory, were larger in magnitude than changes typically observed in healthy adults over decades of life experiences, the scientists say.
Researchers in the field say that after the age of 30, personality doesn't usually change significantly. "Normally, if anything, openness tends to decrease as people get older," says study leader Roland R. The Top 10 Psychology Studies of 2010. The end of 2010 fast approaches, and I'm thrilled to have been asked by the editors of Psychology Today to write about the Top 10 psychology studies of the year. I've focused on studies that I personally feel stand out, not only as examples of great science, but even more importantly, as examples of how the science of psychology can improve our lives.
Each study has a clear "take home" message, offering the reader an insight or a simple strategy they can use to reach their goals , strengthen their relationships, make better decisions, or become happier. If you extract the wisdom from these ten studies and apply them in your own life, 2011 just might be a very good year. 1) How to Break Bad Habits If you are trying to stop smoking , swearing, or chewing your nails, you have probably tried the strategy of distracting yourself - taking your mind off whatever it is you are trying not to do - to break the habit.

That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. It's even possible to make out structures within the cell, such as the nucleus, mitochondria and chloroplasts. To see anything smaller than 500 nm, you will need an electron microscope. Adenine The label on the nucleotide is not quite accurate. How can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake. The X chromosome is shown here in a condensed state, as it would appear in a cell that's going through mitosis. A chromosome is made up of genetic material (one long piece of DNA) wrapped around structural support proteins (histones). Carbon.
