I was a gamer kid. Heck, I still am a gamer kid. And like any form of media, old or new, video games have had their fair share of negative airtime. Much like how comic books were vilified in the 1950s for corroding young and impressionable minds (although the research behind those claims is now in dispute), video games are similarly being scrutinized for their effects on development and behavior.
But a relatively new branch of science is focusing on the therapeutic aspects of video games. This new generation of researchers who have grown up with video games are starting to use their unique mix of skills to look into the possibility of improving people’s lives through gaming. And there’s three promising areas where games appear to have a unique leg up on traditional therapies.
A new toxicology study states that rats eating genetically modified food and the weedkiller Roundup develop huge tumors and die. But many scientists beg to differ, and a close look at the study shows why.
Genetically modified organisms (GMOs) have always been a controversial topic. On the one hand are the many benefits: the higher crop yields from pesticide- and insect-resistant crops, and the nutritional modifications that can make such a difference in malnourished populations. On the other side is the question that concerns many people: We are modifying the genes of our food, and what does that mean for our health? These are important question, but the new study claiming to answer them misses the mark. It has many horrifying pictures of rats with tumors, but without knowledge about the control rats, what do those tumors mean? Possibly, nothing at all.
The recent study, from the Journal of Food and Chemical Toxicology has fueled the worst fears of the GMO debate. The study, by Italian and French groups, evaluated groups of rats fed different concentrations of maize (corn) tolerant to Roundup or Roundup alone, over a two year period, the longest type of toxicology study. (For an example of one performed in the U.S., see here.) The group looked at the mortality rates in the aging rats, as well as the causes of death, and took multiple samples to assess kidney, liver, and hormonal function.
The presented results look like a toxicologist’s nightmare. The authors reported high rates of tumor development in the rats fed Roundup and the Roundup-tolerant maize. There are figures of rats with visible tumors, and graphs showing death rates that appear to begin early in the rats’ lifespan. The media of course picked up on it, and one site in particular has spawned some reports that sound like mass hysteria. It was the first study showing that genetically modified foods could produce tumors at all, let alone the incredibly drastic ones shown in the paper.

The British Medical Journal says that the “widely touted innovation crisis in pharmaceuticals is a myth.” The British Medical Journal is wrong.
There, that’s about as direct as I can make it. But allow me to go into more detail, because that’s not the the only thing they’re wrong about. This is a new article entitled “Pharmaceutical research and development: what do we get for all that money?”, and it’s by Joel Lexchin (York University) and Donald Light of UMDNJ. And that last name should be enough to tell you where this is all coming from, because Prof. Light is the man who’s publicly attached his name to an estimate that developing a new drug costs about $43 million dollars.
I’m generally careful, when I bring up that figure around people who actually develop drugs, not to do so when they’re in the middle of drinking coffee or working with anything fragile, because it always provokes startled expressions and sudden laughter. These posts go into some detail about how ludicrous that number is, but for now, I’ll just note that it’s hard to see how anyone who seriously advances that estimate can be taken seriously. But here we are again.

Last month, CBS Boston aired a story about a man in Massachusetts who caught fire while operating a grill in his backyard. He wasn’t going crazy with lighter fluid, nor was he being careless with propane. No, the culprit was Banana Boat Sport Performance spray-on sunscreen.
But don’t be too quick to blame the orange bottle. After all, this kind of thing does occasionally happen when people spray flammable substances from aerosol cans in close proximity to burning coals. There are, however, other reasons to be suspicious of the summertime mainstay: several recent reports have raised questions about both the effectiveness and safety of sunscreens.
In fact, the National Cancer Institute, a branch of the NIH, declares on its website that studies on sunscreen use and cancer rates in the general population have provided “inadequate evidence” that sunscreens help prevent skin cancer. What’s more, research suggests that some sunscreens might even promote it.
Those are heavy charges for a product that people have long felt so good about using.
By now you may have heard about Oxford Nanopore’s new whole-genome sequencing technology, which has the promise of taking the enterprise of sequencing an individual’s genome out of the basic science laboratory, and out to the consumer mass market. From what I gather the hype is not just vaporware; it’s a foretaste of what’s to come. But at the end of the day, this particular device is not the important point in any case. Do you know which firm popularized television? Probably not. When technology goes mainstream, it ceases to be buzzworthy. Rather, it becomes seamlessly integrated into our lives and disappears into the fabric of our daily background humdrum. The banality of what was innovation is a testament to its success. We’re on the cusp of the age when genomics becomes banal, and cutting-edge science becomes everyday utility.
Granted, the short-term impact of mass personal genomics is still going to be exceedingly technical. Scientific genealogy nuts will purchase the latest software, and argue over the esoteric aspects of “coverage,” (the redundancy of the sequence data, which correlates with accuracy) and the necessity of supplementing the genome with the epigenome. Physicians and other health professionals will add genomic information to the arsenal of their diagnostic toolkit, and an alphabet soup of new genome-related terms will wash over you as you visit a doctor’s office. Your genome is not you, but it certainly informs who you are. Your individual genome will become ever more important to your health care.

Over the week or so, critics have found many reasons to fault Susan G. Komen for the Cure. The scrutiny began with the revelation that the group was halting its grants to Planned Parenthood. The decision seemed like a punitive act that would harm low-income women (the money had funded health services like clinical breast exams), and Komen’s public entry into the culture wars came as a shock to supporters who’d viewed the group as nonpartisan. Chatter on the Internet quickly blamed the move on Komen’s new vice president of Public Policy, Karen Handel, a GOP candidate who ran for governor in Georgia on a platform that included a call to defund Planned Parenthood. Komen’s founder, Ambassador Nancy Brinker, attempted to explain away the decision, and on Tuesdy, Handel resigned her position.
The Planned Parenthood debacle brought renewed attention to other controversies about Komen from recent years—like its “lawsuits for the cure” program that spent nearly $1 million suing groups like “cupcakes for the cure” and “kites for the cure” over their daring attempts to use the now-trademarked phrase “for the cure.” Critics also pointed to Komen’s relentless marketing of pink ribbon-themed products, including a Komen-branded perfume alleged to contain carcinogens, and pink buckets of fried chicken, a campaign that led one rival breast cancer advocacy group to ask, “what the cluck?”
But these problems are minuscule compared to Komen’s biggest failing—its near outright denial of tumor biology. The pink arrow ads they ran in magazines a few months back provide a prime example. “What’s key to surviving breast cancer? YOU. Get screened now,” the ad says. The takeaway? It’s your responsibility to prevent cancer in your body. The blurb below the big arrow explains why. “Early detection saves lives. The 5-year survival rate for breast cancer when caught early is 98%. When it’s not? 23%.”
If only it were that simple. As I’ve written previously here, the notion that breast cancer is a uniformly progressive disease that starts small and only grows and spreads if you don’t stop it in time is flat out wrong. I call it breast cancer’s false narrative, and it’s a fairy tale that Komen has relentlessly perpetuated.

If you were to be diagnosed with cancer, how do you think you would feel? It would depend on the type of cancer of course, but there’s a good chance that no matter the details, the word “cancer” would make the diagnosis much more frightening. Frightening enough, in fact, to do you as much harm, or more, than the disease itself. There is no question that in many cases, we are cancer-phobic, more afraid of the disease than the medical evidence says we need to be, and that fear alone can be bad for our health. As much as we need to understand cancer itself, we need to recognize and understand this risk, the risk of cancer phobia, in order to avoid all of what this awful disease can do to us.
In a recent report to the U.S. National Institutes of Health (NIH), a panel of leading experts on prostate cancer, the second most common cancer in men (after skin), said;
“Although most prostate cancers are slow growing and unlikely to spread, most men receive immediate treatment with surgery or radiation. These therapeutic strategies are associated with short- and long-term complications including impotence and urinary incontinence.”
“Approximately 10 percent of men who are eligible for observational strategies (keep an eye on it but no immediate need for surgery or radiation) choose this approach.”
“Early results demonstrate disease-free and survival rates that compare favorably (between observation and) curative therapy.”
“Because of the very favorable prognosis of low-risk prostate cancer, strong consideration should be given to removing the anxiety-provoking term ‘cancer’ for this condition.”
Let me sum that up. Many prostate cancers grow so slowly they don’t need to be treated right away…the unnecessary treatment causes significant harm…and one of the reasons nine men out of ten men diagnosed with slow-growing prostate cancer accept, indeed choose these unnecessary harms, is because “cancer” sounds scary.
