"There has been much speculation that the lawyers for Jared Loughner, who has been charged in the Tucson shootings, may mount an insanity defense. Since John Hinckley Jr. was acquitted of trying to kill President Reagan, the use of the insanity defense has become very restricted in federal cases. Arizona, along with several other states, no longer allows a finding of not guilty by reason of insanity. In the three decades since the Hinckley case, brain research and brain scans have made many advances in diagnosing and categorizing mental illness. Yet this seems to have little bearing on how society deals with insanity and culpability in the legal arena. What has been learned in the decades since the Hinckley case? Should a better medical understanding of mental illness alter our legal definitions of insanity? Or is the insanity defense rooted in principles or traditions that actually don't have much to do with medicine?"

"PSYCHOTHERAPY is having yet another identity crisis. It has manifested itself in two recent trends in the profession in America: the first involves trying to make therapy into more of a "hard science" by putting a new emphasis on measurable factors; the other is a growing belief among therapists that the standard practice of using talk therapy to discover traumas in a patient's past is not only unnecessary but can be injurious. That psychotherapists of various orientations find themselves under pressure to prove to themselves and to society that they are doing a hard-core science - which was a leading theme of the landmark Evolution of Psychotherapy Conference in California in December - is not really surprising. Given the prestige and trust the modern world gives to scientific standards, psychotherapists, who always have to measure themselves against the medical profession, are going to want to demonstrate that they, too, deal in the predictable; that they, too, can provide evidence for the value of what they do."

"The 21-year-old woman was carefully trained not to flirt with anyone who came into the laboratory over the course of several months. She kept eye contact and conversation to a minimum. She never used makeup or perfume, kept her hair in a simple ponytail, and always wore jeans and a plain T-shirt. Each of the young men thought she was simply a fellow student at Florida State University participating in the experiment, which ostensibly consisted of her and the man assembling a puzzle of Lego blocks. But the real experiment came later, when each man rated her attractiveness. Previous research had shown that a woman at the fertile stage of her menstrual cycle seems more attractive, and that same effect was observed here - but only when this woman was rated by a man who wasn't already involved with someone else. The other guys, the ones in romantic relationships, rated her as significantly less attractive when she was at the peak stage of fertility, presumably because at some level they sensed she then posed the greatest threat to their long-term relationships. To avoid being enticed to stray, they apparently told themselves she wasn't all that hot anyway. This experiment was part of a new trend in evolutionary psychology to study "relationship maintenance." Earlier research emphasized how evolution primed us to meet and mate: how men and women choose partners by looking for cues like facial symmetry, body shape, social status and resources. "

"When reports emerged 30 years ago that young gay men were suffering from rare forms of pneumonia and cancer, public health investigators scrambled to understand what appeared to be a deadly immune disorder: What were the symptoms? Who was most susceptible? What kinds of infections were markers of the disease? They were seeking the epidemiologist's most essential tool - an accurate case definition, a set of criteria that simultaneously include people with the illness and exclude those without it. With AIDS, investigators soon recognized that injection-drug users, hemophiliacs and other demographic groups were also at risk, and the case definition evolved over time to incorporate lab evidence of immune dysfunction and other refinements based on scientific advances. "If you recognize something is happening, you need a case definition so you can count it," said Andrew Moss, an emeritus professor of epidemiology at the University of California, San Francisco, and an early AIDS investigator. "You need to know whether the numbers are going up or down, or whether treatment and prevention work. And if you have a bad case definition, then it's very difficult to figure out what's going on." Once a disease can be diagnosed reliably through lab tests, creating an accurate case definition becomes easier. But when an ailment has no known cause and its symptoms are subjective - as with chronic fatigue syndrome, fibromyalgia and other diseases whose characteristics and even existence have been contested - competing case definitions are almost inevitable. Now a new study of chronic fatigue syndrome has highlighted how competing case definitions can lead to an epidemiologic "Rashomon" - what you see depends on who's doing the looking - and has stoked a fierce debate among researchers and patient advocates on both sides of the Atlantic.

"An online poll conducted in the '90s set Vitaly Komar, Alex Melamid and David Soldier on a quest to create the most annoying song ever. After gathering data about people's least favorite music and lyrical subjects, they did the unthinkable: they combined them into a single monstrosity, specifically engineered to sound unpleasant to the maximum percentage of listeners. The song is not new, but it resurfaced on Dial "M" for Musicology. Amazingly, this "most unwanted music" contains little dissonance - that would have been too easy. For the most part, they seem to have tried to assemble these elements in a listenable way. Komar & Melamid and David Soldier's list of undesirable elements included holiday music, bagpipes, pipe organ, a children's chorus and the concept of children in general (really?), Wal-Mart, cowboys, political jingoism, George Stephanopoulos, Coca Cola, bossanova synths, banjo ferocity, harp glissandos, oompah-ing tubas and much, much more. It's actually a fascinating listen, worthwhile for the opera rapping alone. (We didn't think that was possible either.)"

"A new exhibition about the brain tries to bring visual arts and science together. But it's a false premise. Art does not help us understand how the world works - and to merge the two disciplines trivialises them both"

"Prosecutors here noted that she is also in the vanguard of a growing trial trend: in Arizona, Hawaii, Idaho, Indiana and some other states in the last few years, courts have allowed such trained dogs to offer children and other vulnerable witnesses nuzzling solace in front of juries. The new role for dogs as testimony enablers can, however, raise thorny legal questions. Defense lawyers argue that the dogs may unfairly sway jurors with their cuteness and the natural empathy they attract, whether a witness is telling the truth or not, and some prosecutors insist that the courtroom dogs can be a crucial comfort to those enduring the ordeal of testifying, especially children. The new witness-stand role for dogs in several states began in 2003, when the prosecution won permission for a dog named Jeeter with a beige button nose to help in a sexual assault case in Seattle. "Sometimes the dog means the difference between a conviction and an acquittal," said Ellen O'Neill-Stephens, a prosecutor there who has become a campaigner for the dog-in-court cause. "

"Born without his fibulas, the long bones that span from the knees to the ankles, Pistorius relies on carbon-fiber prosthetic limbs to propel him around the track in times comparable to some of the world's top runners. And therein remains the question that has been the crux of a continuing debate: do those high-tech legs give him an unfair advantage? "

"During the summer of 2008, the eminent Notre Dame sociologist Christian Smith led a research team that conducted in-depth interviews with 230 young adults from across America. The interviews were part of a larger study that Smith, Kari Christoffersen, Hilary Davidson, Patricia Snell Herzog and others have been conducting on the state of America's youth. Josh Haner/The New York Times Smith and company asked about the young people's moral lives, and the results are depressing. It's not so much that these young Americans are living lives of sin and debauchery, at least no more than you'd expect from 18- to 23-year-olds. What's disheartening is how bad they are at thinking and talking about moral issues. The interviewers asked open-ended questions about right and wrong, moral dilemmas and the meaning of life. In the rambling answers, which Smith and company recount in a new book, "Lost in Transition," you see the young people groping to say anything sensible on these matters. But they just don't have the categories or vocabulary to do so. "

Once, experts feared that young children exposed to more than one language would suffer "language confusion," which might delay their speech development. Today, parents often are urged to capitalize on that early knack for acquiring language. Upscale schools market themselves with promises of deep immersion in Spanish - or Mandarin - for everyone, starting in kindergarten or even before. Yet while many parents recognize the utility of a second language, families bringing up children in non-English-speaking households, or trying to juggle two languages at home, are often desperate for information. And while the study of bilingual development has refuted those early fears about confusion and delay, there aren't many research-based guidelines about the very early years and the best strategies for producing a happily bilingual child. But there is more and more research to draw on, reaching back to infancy and even to the womb. As the relatively new science of bilingualism pushes back to the origins of speech and language, scientists are teasing out the earliest differences between brains exposed to one language and brains exposed to two. Researchers have found ways to analyze infant behavior - where babies turn their gazes, how long they pay attention - to help figure out infant perceptions of sounds and words and languages, of what is familiar and what is unfamiliar to them. Now, analyzing the neurologic activity of babies' brains as they hear language, and then comparing those early responses with the words that those children learn as they get older, is helping explain not just how the early brain listens to language, but how listening shapes the early brain. Recently, researchers at the University of Washington used measures of electrical brain responses to compare so-called monolingual infants, from homes in which one language was spoken, to bilingual infants exposed to two languages. Of course, since the subjects of the study, adorable in their

"Everything has beauty, but not everyone sees it. ~ Confucius The word "beauty" is the most overused, misunderstood, poorly defined word in the English language. What makes a woman beautiful? The Holy Grail of beauty has never been completely understood. The cliché, "Beauty is in the eye of the beholder," is incorrect in my opinion. Perception is the key. It is "perception of beauty" that is in the eye of the beholder. Each of us, however, has a different perception of beauty. We all have different tastes, likes and dislikes, and this affects our definition and perception of beauty with regard to the American woman. As a plastic surgeon, it is my job to counsel people about this perception of beauty because so many misconceptions exist."

"In 1990, Thomas J. Bouchard, Jr. and his colleagues at the University of Minnesota published a striking finding: About 70 percent of the variance in IQ found in their particular sample of identical twins was found to be associated with genetic variation. Furthermore, identical twins reared apart were eerily similar to identical twins reared together on various measures of personality, occupational and leisure-time interests, and social attitudes. Bouchard's study, along with many others, has painted a consistent picture: Genes matter. The studies say nothing about how they matter, or which genes matter, but they show quite convincingly that they indeed do matter. Genes vary within any group of people (even among the inhabitants of middle-class in Western society), and this variation contributes to variations in these people's behaviors. Let's be clear: Twin studies have received much criticism. Even though the proliferation of advanced statistical techniques (such as structural equation modeling) and the implementation of additional controls have allayed some of the concerns, they haven't allayed all of the them. Even so, the findings from twin studies should not be understated; it counters many a prevailing belief that we are born into this world as blank slates, completely at the mercy of the external environment. Because our psychological characteristics reflect the physical structures of our brains and because our genes contribute to those physical structures, there are unlikely to be any psychological characteristics that are completely unaffected by our DNA.
