The topic of sports injuries is unavoidable these days-- the sports radio shows I listen to in the car probably spend an hour a week bemoaning the toll playing football takes on kids. Never a publication to shy away from topics that bring easy clicks, Vox weighs in with The Most Dangerous High School Sports in One Chart. You can go over there to look at their specific chart, which is drawn from a medical study of cheerleading; I don't find the general ordering of things all that surprising. There was, however, one aspect of this that I found sort of surprising, namely the difference between…

I've decided to do a new round of profiles in the Project for Non-Academic Science (acronym deliberately chosen to coincide with a journal), as a way of getting a little more information out there to students studying in STEM fields who will likely end up with jobs off the "standard" academic science track. Seventh in this round is a physics major who went into teaching high school, then decided to try medical school, and now works with the youngest possible subjects. He also had the excellent taste to send along a picture of himself with his dog... 1) What is your non-academic job? I am the…

A little while back, I was put in touch with a Wall Street Journal writer who was looking into a new-ish health fad called "earthing," which involves people sleeping on special grounded mats and that sort of thing. The basis of this particular bit of quackery is the notion that spending time indoors, out of contact with the ground, allows us to pick up a net positive charge relative to the Earth, and this has negative health consequences. Walking barefoot on the ground, or sleeping on a pad that is electrically connected to ground via your house's wiring, allows you to replace your lost…

Jonah Lehrer has a big article at Grantland on concussions in high school football that paints a fairly bleak picture: The sickness will be rooted in football's tragic flaw, which is that it inflicts concussions on its players with devastating frequency. Although estimates vary, several studies suggest that up to 15 percent of football players suffer a mild traumatic brain injury during the season. (The odds are significantly worse for student athletes -- the Centers for Disease Control and Prevention estimates that nearly 2 million brain injuries are suffered by teenage players every year.)…

Unlike the previous post, this is not a rhetorical question that I will ask and then answer. I genuinely do not know the answer. I could Google it, of course, but I'd like to see if somebody reading this is able to deduce the correct answer from the available evidence. So, here's the deal: as an attempt to recover from a rather sedentary couple of months due to computer-based work and some plantar fascitis kind of problem in my foot that's keeping me from playing hoops as much as I'd like, I'm spending a while each day on the exercise bike we have upstairs. While I do a bunch of reading of…

(This post is part of the new round of interviews of non-academic scientists, giving the responses of Jennifer Saam, who translates between different departments at a medical diagnostic laboratory. The goal is to provide some additional information for science students thinking about their fiuture careers, describing options beyond the assumed default Ph.D.--post-doc--academic-job track.) 1) What is your non-academic job? I am a medical science liaison at a medical diagnostic laboratory. I work in the medical services department and this department maintains the scientific integrity for the…

(This post is part of the new round of interviews of non-academic scientists, giving the responses of Will Hendrick, who worked as a lab tech before returning to school. (This may seem like an odd inclusion, but there are people who do this sort of thing forever, so I think it's valid.) The goal is to provide some additional information for science students thinking about their future careers, describing options beyond the assumed default Ph.D.--post-doc--academic-job track.) 1) What is your non-academic job? My official job title was 'Biological Materials Technician', and I worked for…

Thursday's post about the troubles of biomedical scientists drew a response from Mad Mike saying that, no, biomedical science Ph.D.'s really don't have any career options outside of academia, and pointing to Jessica Palmer's post on the same subject for corroboration. Jessica writes: This is something I've tried to explain many times to nonscientists: most of the esoteric techniques I mastered during my thesis aren't useful outside a Drosophila lab. They're not transferable to any other field of biology, let alone any other scientific or nonscientific profession. Those skills I picked up on…

Via Mad Mike, a discussion of why it sucks to be a biomedical scientist: 87% of my blog-related e-mail is from unhappy, bitter, troubled, distraught biomed grad students, postdocs, technicians, and early-career faculty. Others write to me with problems, but these tend to be of the "I'm frustrated with my advisor" sort rather than the "I'm being tortured, abused, deported, sued, and I fear my academic career is over" sort that I routinely get from biomed people. I specify biomedical rather than the life science in general because, as far as I can tell, the ecologists and botanists and…

So, if you look at this picture: You might be asking yourself "Why does Debbie Harry rate Secret Service protection?" But no, this isn't a photo from some alternate universe where the lead singer of Blondie went on to become leader of the free world, it's part of the Rock Stars of Science campaign by the Geoffrey Beene Foundation. They've just rolled out a new campaign in GQ magazine, putting seventeen prominent biomedical researchers in fancy photo spreads with eight different musicians. It's part of an initiative to raise the profile of science by portraying scientists in a more glamorous…

There's a new medical study of the effects of alcohol consumption that finds a surprising result: Controlling only for age and gender, compared to moderate drinkers, abstainers had a more than 2 times increased mortality risk, heavy drinkers had 70% increased risk, and light drinkers had 23% increased risk. A model controlling for former problem drinking status, existing health problems, and key sociodemographic and social-behavioral factors, as well as for age and gender, substantially reduced the mortality effect for abstainers compared to moderate drinkers. However, even after adjusting…

SteelyKid had her two-year checkup this morning, which means we got new weight and length measurements for her. It's been a while since I did anything really dorky with her data, so here are a couple of graphs tracking her growth: (Yes, they're in English units, not SI. Deal with it.) Using the rule of thumb somebody mentioned a while back that a person's final height is double their height at age 2, this projects her to be a bit over 5'9", so that's a prediction we'll be able to test in another fifteen years or so. There's some fairly large uncertainty in these, though, especially today's…

This Slate story on the number of Americans who can't swim was kind of surprising to me: In a 1994 CDC study, 37 percent of American adults said they couldn't swim 24 yards, the length of a typical gymnasium lap pool. A 2008 study conducted by researchers at the University of Memphis found that almost 54 percent of children between 12 and 18 can do no more than splash around the shallow end of a pool. The difference between the two studies is somewhat surprising, as the CDC study suggested that children tend to be better swimmers than adults. Having grown up in a town that features a large-…

The New York Times today has a story with the provocative title Getting Into Med School Without Hard Sciences, about a program at Mount Sinai that allows students to go to med school without taking the three things most dreaded by pre-meds: physics, organic chemistry, and the MCAT: [I]t came as a total shock to Elizabeth Adler when she discovered, through a singer in her favorite a cappella group at Brown University, that one of the nation's top medical schools admits a small number of students every year who have skipped all three requirements. Until then, despite being the daughter of a…

Voting has closed on the Laser Smackdown poll, with 772 people recording their opinion on the most amazing of the many things that have been done with lasers in the fifty years since the invention of the first working laser (see the Laserfest web site for more on the history and applications of lasers). The candidates in the traditional suspense-building reverse order: Lunar laser ranging 22 votes Cat toy/ dog toy/ laser light show 41 votes Laser guide stars/ adaptive optics 46 votes Holography 47 votes Laser eye surgery 53 votes Optical storage media (CD/DVD/Blu-Ray) 60 votes Laser…

We're just over 600 votes in the Laser Smackdown poll in honor of the 50th anniversary of the laser, as of early Friday morning. I notice that it has moved off the front page of the blog, though, so here's another signal-boosting repost, just so we have as many votes as possible, to establish maximum scientific validity when we declare the winner the Most Amazing Laser Application of All Time Which of the following is the most amazing application of a laser?Market Research Voting will remain open until next Sunday, May 2, just two days from now, with the ultimate winner announced on Monday…

In 1960, the first working laser was demonstrated, and promptly dubbed "a solution looking for a problem." In the ensuing fifty years, lasers have found lots of problems to solve, but there has been no consensus about which of the many amazing applications of lasers is the most amazing. Now, in 2010, as we celebrate the anniversary of the laser, we finally have the technology to definitively answer the question: radio-button polls on the Internet! Which of the following is the most amazing application of a laser?Market Research Each of the choices above links to a post I wrote here giving…

What's the application? Using lasers to cut and/or cauterize tissue during surgical procedures, instead of the traditional very small very sharp knives. What problem(s) is it the solution to? 1) "How can we do surgery without touching the tissues being operated on?" 2) "How can I get rid of these annoying glasses/contact lenses?" How does it work? First, you strap a device to your head that lets you shoot laser beams from your forehead, like one of the X-Men. then you use a magnifying glass to focus it to where it needs to be. Like so: (I'm not sure exactly what sort of procedure that is,…

This Timothy Burke post on the current political moment deserves better than to be buried in the Links Dump. He's beginning to despair because it looks like "there are many things which could happen which would improve the lives of many Americans which are not going to happen and perhaps cannot happen." Take health care, for example. I can read and parse and think about the proposed legislation that actually exists and see it without hyperbole, as an okay if scattered series of modest initiatives. Whatever. I think I have a fairly good handle on the underlying cultural and social…

While I'm thrilled to see How to Teach Physics to Your Dog listed on Amazon, I am distressed to see it offered as a pair with something called The Intention Experiment by Lynne McTaggart. I'm not linking to the Amazon page for that book, because it's a giant pile of crap, and I wouldn't want anyone to accidentally one-click-order it after following a link from my page. If you should choose to look it up, you can read bits and pieces of it via the "Look Inside" feature, and it's true that the opening chapter or so is a reasonable-sounding description of the physics of quantum entanglement,…
