America loves football. Brutal, high-flying, smash-mouth football.
The players seem like gladiators from another era. Chiseled out of stone, they feel no pain as they run, jump, and catch with a grace that appears super-human.
The reality is, however, that they do feel pain—and often are playing injured. As news of the most recent lawsuit against the National Football League unfolds, the realities of America’s favorite sport are slowly being revealed–retired players are claiming that the NFL got them addicted to painkillers.
There are several legal factors to consider in such a claim: did the NFL act recklessly, negligently, or maliciously? Did they create a culture that encouraged drug abuse? Were players informed of side effects and drug interactions?
Most of the drugs mentioned in this case (Oxycontin, Percocet, and Vicodin) are prescription opioids, which have a long history of abuse and addiction. These drugs act on opioid receptors of the central nervous system relieving pain and causing feelings of euphoria.
While the legalities of this particular claim will likely be argued for a long time, the question remains: why are prescription opioids used so often for pain relief, and why are they so addictive?

The Defense Advanced Research Projects Agency (DARPA) has been a major funding source for the development of unique and innovative technologies under its motto of “driving technological surprise.” Some of DARPA’s current projects include designing bullets that can adjust their course in-flight, novel techniques to investigate brain function (see my previous post on CLARITY), and brain-controlled prosthetic limbs.
As if the line between reality and science fiction was not blurred enough, aid is now being given to researchers for the development of a prosthetic device that will improve the recall and formation of long-term memories.

“Perhaps it had something to do with living in a dark cupboard, but Harry had always been small and skinny for his age…[he] had a thin face, knobbly knees…and wore round glasses held together with a lot of Scotch tape because of all the times Dudley had punched him on the nose.”
And so we are introduced to The Boy Who Lived, the Chosen One—the famous Harry Potter. His seven books have been translated into 73 different languages and sold over 450 million copies worldwide.
But readers wouldn’t guess, after author J.K. Rowling’s introduction of Harry in Chapter 2, that the orphaned boy would be the one to defeat the powerful and devastating Dark Lord Voldemort. Snubbed by his only remaining family, bullied by his cousin and classmates, and residing in the cupboard under the stairs, Harry is short, skinny, and totally non-threatening.
And it’s clear to us why. His Uncle Vernon, Aunt Petunia, and cousin Dudley Dursley—to whom he was passed as an infant after the death of his parents— ensure that he’s properly malnourished at all times. After spending a day cleaning the Dursleys’ entire house and doing yardwork in the blazing July heat (on his 12th birthday, no less), Aunt Petunia prepares for Harry “two slices of bread and a lump of cheese” before sending him off to hide during their dinner party with the Masons. It’s no wonder he’s so small for his age.
But perhaps something other than the physical abuse held back his growth, too. Beyond the malnourishment, it’s possible that Harry Potter suffered from what is known as psychosocial short stature.

The concept of receptor-drug interaction has been the main mechanism for how drugs develop their clinical benefits. Drugs generally have target molecules and regulate their activity to make significant changes originated in cells.
My research field is the dopamine D1 receptor, and it has been a promising drug target because its activation has shown to improve the symptoms of at least two neurodisorders: motor symptoms of Parkinson’s disease and verbal working memory in schizotypal personality patients.
Nonetheless, more desirable D1 receptor activators are still required to maximize clinical efficacy and applications because the current D1 activators have several side effects and pharmacokinetic issues.

Have you ever heard a friend exclaim “I’m being so OCD right now!” when they can’t help but double check for their house keys before slamming the front door? It seems that this phrase has become a cultural colloquialism, it is used so often.
Luckily, most people who say “I am so OCD!” do not, in fact, have a debilitating anxiety disorder marked by uncontrollable obsessive thoughts and behavioral compulsions, the hallmark features of obsessive-compulsive disorder.
Though the term obsessive-compulsive is often misattributed to those of us who are perhaps too meticulous, prone to anxiety, or a combination thereof, we as a society have familiarized ourselves with the term through our exposure to literature and media to the extent that it is now a part of our lexicon.

Researchers who study genetic interactions—of which there are thousands currently under study and billions more to be studied—often find themselves trying to explain their field to non-technical audiences.
And if there’s anything I’ve learned as a student who has taken various levels of human genetics as an undergraduate and now at the graduate level, it’s that the average person has many preconceived notions about genetics that are mostly inaccurate, if not altogether wrong. These misconceptions are often perpetrated and perpetuated by our educational systems and media that aim to simplify a field that is intrinsically un-simple.
There are few absolute truths when it comes to human genetics. Absolutely, there are disease genes, but there are also modifiers of disease genes, and modifiers of modifiers of disease genes. It goes on. Incomplete penetrance, genetic heterogeneity, pleiotropy, and gene-environment interactions—these are just some of the factors that make studies of relatively simple-seeming genetic diseases extremely challenging.
Since launching last May, Lions Talk Science has published over 30 blog posts written and edited by a bevy of talented, diverse graduate students at Penn State College of Medicine.
The blog has been featured in a publication by the Association of American Medical Colleges, received thousands of page views, and has been widely shared with local and national high school and college educators as well as the Pennsylvania Society for Biomedical Research. Posts are enjoyed by both the lay and academic communities thanks to strong support from our Medical Center and College of Medicine social media team.

There are an endless number of diet plans available today that purport to be the answer to all of our weight loss needs.
Most of them are based on calorie restriction or minimizing intake of one of the major macromolecules found in food – fats, carbohydrates, and proteins. Probably the most famous example of this is the Atkins diet, which suggests you cut carbohydrates out of your diet and sustain yourself on protein and fat.
Although these diet systems have led to weight loss for many people, we should be careful about upsetting the balance of the macromolecules we ingest. After all, the body needs all of them to function properly.

During my first year at Penn State College of Medicine, I participated in an MRI research study. I laid in an MRI machine for 45 minutes and looked at pictures of chocolate while smelling chocolate odors. Tough life, right?
(Hershey really is the sweetest place on Earth…even in the labs!)
The MRI machine is rather big, rather loud (I wore headphones), and…rather claustrophobic. But it operates on a rather GENIUS principle!
