Do you remember your mother’s facial expression when you brought home another birthday party invitation in 3rd grade? Through those clenched teeth, she was secretly dreading the sugar-induced hyperactivity that she was going to have to deal with after Jimmy’s mom shipped you back. Calculating the grams of sugar in the cake, Kool-Aid, and goodie bags, her apprehension was almost palpable.
Everyone “knows” that sugar induces hyperactivity in children, but the research does not support this belief. An article published in the British Medical Journal in 2008 reported that twelve double-blinded, randomized control trials failed to see a difference in the behavior of children placed on sugar versus non-sugar diets. Like at a birthday party, the researchers fed children sugar from sweets and chocolates. Interestingly, none of the studies reported a difference in behavior even in the children who were considered “sensitive” to sugar, including those with attention-deficit hyperactivity disorder.

Ladies and gents, have you ever wondered what drinking does to the brain, besides make you look like one class act of a gent (picture provided for those who’d like to emulate such)? I mean, I’m sure that’s what you’re all talking about come Saturday night when you’ve got a sex on the beach in your hand and you’re mmms mmmsing on the dance floor. (Gents, I know that’s your preferred drink. Don’t be ashamed.) Well, copious drinking can cause a neurological disease called Korsakoff’s Syndrome. I’m talking ‘bout more than your average beer-bellied frat boy drinking. (Frat boys, if you’re reading, don’t fret too much…) Anyhoo, the main symptom of Korsakoff’s is confabulation--in lay-man’s terms, flat-out lying--but, get this, the person whole-heartedly believes their lies.

Imagine Emma Sue Schroeder, an 83-year-old terminal cancer patient who wants her doctor to prescribe lethal pills for her. Should that be legal?
On April 2, Prof. Felicia Ackerman (PHIL) discussed the above scenario in a Science Café hosted by The Triple Helix called “The Double Standard in Physician-Assisted Suicide.” Ackerman is well-known as the writer of well over a hundred letters to the editor in The New York Times and as the writer of a column in The Providence Journal. Ackerman teaches PHIL0030 “Skepticism and Knowledge” and PHIL0880 “Ethical Themes in the Contemporary American Short Story.”
Ackerman argued that, out of respect for Rachel’s autonomy, it should be legal for lethal pills to be prescribed to Rachel and contended that government should not deal in morality.

In the United States, the biomedical significance of human embryonic stem cells (hESC) is recognized by Democrats and Republicans alike. Every passing month brings reports of the newest successful application of embryonic stem cells to a specific medical cause. hESC therapy has been used to further research on a wide variety of ailments – including spinal cord injury, multiple sclerosis, infertility and even hearing loss (1) – and it has generated largely promising results.
The controversy with hESC research does not center on the results but the methods – a moral dilemma that has been greatly debated in the media for years. Embryonic stem cells are derived from four- to five-day-old blastocysts, hollow balls of cells that represent the beginning stage of human embryo development. The extraction procedure often results in the destruction of a human embryo, usually one that has been voluntarily donated in a fertility clinic. But the huge potential of these cells has caused scientists, politicians, and the general public (2) to come to terms with this fact.
Over the last two to three years, embryonic stem cells have, more or less, crawled off the agenda of the general media. Government-sponsored research for embryonic stem cells is currently at a pinnacle, yet it remains hindered due to one small piece of decade-old legislation

Pain is perhaps our most important sense for survival – it warns us with a piercing signal that our body has sustained damage. However, it is unpleasant by nature.
The search to relieve pain dates back to at least 3400 BC, when ancient Sumerians used opium (1). In modern times, with advances in science and technology, we have a much more diverse and refined list of chemical agents for various medical purposes.
The advent of inhalant anesthesia contributed immensely to the development of modern general anesthesia. Currently, the most commonly used inhalational anesthetic agents are isoflurane, desflurane, sevoflurane, and nitrous oxide. When the idea of inhalational anesthesia first began to emerge, scientists focused on nitrous oxide and ether gas, largely due to their familiarity to people. Both gases were well known for their hypnotic effect. Nitrous oxide is also known as “laughing gas,” and was used recreationally to induce euphoria often accompanied by giggling, primarily at parties and in traveling shows (2, 3).

Three-letter acronyms abound in our society – NRA, NBA, CDC – and often name agencies that seldom interact. However, an unlikely friendship has recently formed between two three-letter permutations that seem to occupy opposite sides of the spectrum: NFL and NIH. In 2012, the NFL – yes, the National Football League – donated a whopping $30 million to the Foundation for the National Institutes of Health to fund research on traumatic brain injury – a subject that hits close to home for the NFL and its players.
Traumatic brain injury (TBI) is a serious public health problem with an ever-widening scope of severity. It is currently the number one cause of death amongst young adults  and is a particular menace to young athletes. Perhaps even more frightening than its prevalence is its nebulosity. We have no rapid, reliable diagnostic methods for concussions and know little about the long-term consequences of repetitive insult to the head other than the high risk of developing progressive brain degeneration, chronic traumatic encephalography (CTE). Brains afflicted by CTE show demonstrable physical damage, including excess protein build up and tangled cells. CTE produces symptoms analogous to those of Alzheimer’s – irritability, confusion, depression, mood swings, memory loss, and cognitive difficulties. Preliminary tests have revealed that several former high-profile athletes, including Hall of Fame running back, Tony Dorsett, may be living with CTE. Fifty-four former-NFL players have donated their brains for scientific analysis post-mortem to the Center for the Study of Traumatic Encephalopathy at Boston University. Fifty-two of said brains show marked signs of brain damage from repeated concussions .

When asked how he remains sane while studying the psychological effects of harrowing experiences, renowned psychiatrist and author Robert J. Lifton replies, "I draw bird cartoons."
"We need a sense of absurdity, sometimes gallows humor, to survive the absurdities of our world," said Dr. Lifton in a speech entitled "Research as Witness: A Psychiatrist’s Struggles with Extreme Events," delivered at Brown on October 21, 2013 as the 21st annual Harriet W. Sheridan Literature and Medicine Lecture.
The 87-year-old Brooklyn native has held positions at Harvard, Yale, and the John Jay College of Criminal Justice. He has published over 20 books on the psychological consequences of historical events.
Over the course of his career, Lifton has interviewed American prisoners of war, survivors of Hiroshima, and Nazi doctors. After two years in the Air Force in Korea and Japan, Lifton embarked on the "struggle to bring together psychology and history." Eschewing the ideally objective approach of scientific research, Dr. Lifton found himself constantly motivated by ethical concerns and a desire to participate in what he calls "relevant activism."

Sex differences can create problems both in pain and its treatment. This topic adds yet another aspect to today’s complex sex/gender equality debate, but it’s highly relevant for anyone who experiences pain – namely, everyone. Research has revealed that males and females perceive pain differently, yet management of pain for men and women doesn't take that into account. In fact, treatment of pain is often generalized for both sexes (or worse, biased). Instead, doctors should tailor treatments to the differences in female and male bodies’ responses to pain and pain medicine. To do this, though, greater research is needed on sex-specific responses to pain treatments.
