Grohol, Psy.D. on June 8, 2012 Swedish researchers report the successful trial of a vaccine that helps individuals develop protective antibodies that can prevent progression of Alzheimer’s disease. Alzheimer’s is a neurological dementia disease in which the body attacks itself destroying brain cells. The disease is on the upswing with the World Health Organization declaring that dementia is the fastest growing global health epidemic of our age.
What Thomas Kuhn Really Thought about Scientific “Truth” In 1991, when I was a staff writer for Scientific American, I wrote a letter to Thomas Kuhn, then at MIT.
I said I wanted to profile him for Scientific American and “tell readers how you developed your views of the process of science.” Back to Basics: Four (Free) Online Psychology Courses. I live in a college town.

Then along came Albert Einstein, who showed that different observers can disagree about the length of objects and the timing of events. His theory of relativity unified space and time into a single entity - space-time. But did Einstein's revolution go far enough? Think healthy, eat healthy: Scientists show link between attention, self-control. (Medical Xpress) -- You're trying to decide what to eat for dinner.
Should it be the chicken and broccoli? The super-sized fast-food burger? Epigenetic 'memory' key to nature versus nurture. Researchers at the John Innes Centre have made a discovery, reported this evening (24 July) in Nature, that explains how an organism can create a biological memory of some variable condition, such as quality of nutrition or temperature.
The discovery explains the mechanism of this memory -- a sort of biological switch -- and how it can also be inherited by offspring. The work was led by Professor Martin Howard and Professor Caroline Dean at the John Innes Centre. Symphony of Science.

The Double Life of Women. Step into any bar or party and it won't take you long to spot her. Why Do We Like The Taste Of Protein? For a long time, the mechanisms of taste seemed relatively straightforward.
For one thing, it’s been all about the tongue, that exposed sensory muscle lying limp in our mouth. Ever since Democritus hypothesized in the fourth century B.C. that the sensation of taste was an effect of the shape of food particles, the tongue has been seen as a simple sensory organ. Rewriting the textbooks: When science gets it wrong. Link found between environment, genetics in triggering multiple sclerosis. Environmental and inherited risk factors associated with multiple sclerosis – previously poorly understood and not known to be connected – converge to alter a critical cellular function linked to the chronic neurologic disease, researchers with the UC Irvine Multiple Sclerosis Research Center have discovered.
The findings, which appear in the online, open-access journal Nature Communications, suggest that a unifying mechanism may be responsible for multiple sclerosis and point to therapies personalized according to genetic factors. "MS results from complex interactions between an individual's genetics and his or her environment," said study leader Dr. Michael Demetriou, a UCI neurologist and associate director of the Multiple Sclerosis Research Center. How can we corral data to reveal the big picture? Reading a Carl Sagan essay could allow you to find meaning in the universe … using science.

Japanese and U.S. scientists in the young field of epigenetics Thursday reported a rationale as to how specific genes are silenced and others are not. Because this effect can be reversed, it may be possible to devise therapies for cancer and other diseases using this information. The NOVA U.S. public television program described epigenetics as "The Ghost In Your Genes. " It is the study of changes in gene expression that occur without changes in DNA sequence. Like keys on a piano, DNA is the static blueprint for all the proteins that cells produce.
Epigenetic information provides additional dynamic or flexible instructions as to how, where and when the blueprint will be used. The study by Dr. "DNA methylation marks are reversible, so there is great interest in devising therapeutic strategies, for instance in cancer biology, to epigenetically reactivate silenced tumor-suppressor genes or inactivate specific oncogenes in human cancer cells," Dr.
