The swell of content | Gene Expression
In the 1980s my family went and visited friends in Queens for a week in August. Down the street from the house there was a small shop with an arcade machine with Legendary Wings. Every day I’d start out with a fistful of quarters and pop them into the machine to get round after round. Eventually I purchased a version of the game for the original NES, and got so proficient at it that I could win basically on mental autopilot.
I thought of that when listening to a story on the radio about the decline of the home video gaming industry as a revenue generator. Here’s the relevant section of the transcript:
HENN: It’s in a state of flux. Sales and revenue for the big gaming consoles — like Nintendo and Xbox — actually fell last year something like 13 percent. It’s still a $10 billion industry, but that was a big drop.
VIGELAND: It is indeed. What’s going on?
HENN: Some of the smartest people in the industry say the price of what people are willing to pay for an hour of entertainment, for a video game, is dropping like a rock. Bing Gordon was the creative director for ...

So I started eating meat again…
Yes, this from the guy who once said that meat eaters are bad people.
I guess that must make me a bad person.
Well, unlike many other carnivores, I'm at least cognizant of the fact that I'm exploiting animals for my own well-being. While I have made the move to a diet that contains meat, I am not completely at peace with it. I am fully aware and respectful of the fact that the meat on my plate comes at at price, that being the life of another animal.
But I have my reasons. My decision to eat meat again was driven by health concerns. I was a vegetarian for over ten years and I did so primarily for ethical reasons. It was in the last several years of being a vegetarian, however, that I grew increasingly concerned about my health. An increasing number of studies started to point at the importance of meat protein and animal fat—not to mention the perils of soy (which was a staple for me). Moreover, my performance at the gym was stalling. My energy levels were consistently low and I was making very little gains. This was an indication to me that something wasn't right.
So, after a decade of avoiding meat, I was curious to see if a reintroduction to animal protein could change the situation. I switched to the Paleo diet and within three months my BMI went down from 17% to 12% and I gained nearly ten pounds of muscle mass. I was astounded. And add to that an improved sense of well-being, mental clarity and energy— I was sold. My experiment with eating meat exceeded even my own expectations.
Now just because I'm eating meat again doesn't mean I have to be an asshole about it. Like I said earlier, I am still concerned about the well-being of animals. It's for this reason that I'm striving to be the conscious carnivore. I only eat meat from grass-fed animals that have been allowed to graze in pasture and the eggs I eat come from free-range chickens. Yes, my grocery bills are two to three times as much as they used to be, but it's a price I'm happy to pay. I feel better knowing that the meat on my plate came from an animal that actually lived a reasonably good life.
Okay, before I bury you in all this contriteness, there's something else that needs to be said. While I agree that many meat eaters can be obnoxious, inconsiderate and self-righteous in celebration of their carnivorousness, there is an equally pernicious sentiment among vegetarians that needs to be called out: the false notion that a vegetarian or vegan diet is actually good for you. Like the meat eater who needs to acknowledge the harm they're meting out as a consequence of their dietary choices, the vegetarian needs to acknowledge the fact that their diet is far from ideal.
A vegetarian's choice to avoid meat for ethical or environmental reasons is truly noble. They are willing to sacrifice their own health in order to mete out as little harm as possible. I bow down to these people in deep and profound respect.
But that said, vegetarians should not claim that their diet is optimal—because many of them do. The avoidance of meat protein and animal fats, plus the heavy reliance on soy and carbohydrates, is far from ideal. As a person concerned about his health, and as someone who feels that there are reasonable ethical options available for meat consumption, I have consciously (and perhaps selfishly) chosen to avoid a sub-optimal diet. I have come to recognize the fact that the human body evolved to eat meat, and that in order for me to live and be at my best, I need to be an omnivore.
Lastly, as a bioethicist who has strived to walk-the-walk, I am increasingly coming to grips with the fact that I cannot live an ethically or morally perfect life and that I should stop trying. I'll continue to do my best to put out as little harm into the world as possible, but existential perfection is no longer my goal.
As for my animal rights advocacy work, that still remains a top priority. I'll continue to push for better conditions at factory farms (if not the elimination of factory farming altogether), the development of cultured meat, and of course, extended rights for nonhuman animal persons.
For my vegetarian and vegan friends and colleagues, I hope you understand and continue to support me and my work.

Happy birthday, GLAST/Fermi! | Bad Astronomy
On June 11, 2008 — three years ago today — NASA launched the Gamma-ray Large Area Space Telescope into orbit:
Fermi — as it was renamed once it reached orbit, after the great Italian scientist Enrico Fermi — is designed to observe gamma rays, the highest energy flavor of light. Gamma rays are only emitted from the most violent events in the universe: black holes gobbling down matter, exploding stars, antimatter particles annihilating each other, and so on. Fermi surveys the sky day after day, returning gobs of data to waiting scientists.
I was involved with Fermi when it was still called GLAST. Long before launch, I signed on to do education and public outreach for GLAST at Sonoma State University. Along with our team, I wrote web pages and helped create educational activities — including classroom lessons, a card game, a paper model of GLAST, a planetarium show, a PBS NOVA episode… we even built a small observatory near the University to augment GLAST observations! You can find all this on the SSU Fermi website.
Fermi has been a very successful mission, and I’m proud ...

Bare-To-The-Bone Riddle
UPDATE: Solved by Patrick at 12:10 CDT
Wow, I’m so behind in my posts, I think I’m about to catch back up with myself. Pitiful… pitiful. I haven’t forgotten, I’ve simply had no time. Hopefully, things will “free up” later this coming week, and I’ll be able to relocate my rear end with both hands and a GPS.
I had fun with last Saturday’s SciFi riddle (although Rob hopped on it like a starving cheetah after a pot roast – solved it so fast my ears rang), so I thought I’d linger in the world of scientific speculation. That’s right, sports fans; today’s riddle subject is SciFi, so if you’re ready… it’s ONE for the money, TWO for the show, THREE to get ready, and FOUR to GET YOUR GEEK ON!
Radioactive rain
This is a thing, sort of.
Then again, it’s a place.
Or maybe it’s more of a conspiracy.
Really, what IS it?
It’s a dystopia.
It’s a utopia.
It’s both; it’s neither.
But it’s so bright, you gotta’ wear shades.
This owes a lot to Plato, Descartes, and Zhuangzi.
It also gives a wink to a Star Trek (TOS) third season episode.
It’s the age-old battle of man against machine.
How’s that for a riddle? You’ll notice a lack of many pictures on this one… let me know if the pictures really help you solve the riddle or not.

Captain America’s Enlistment and Experimentation: Was It Ethical? | Science Not Fiction
Steve Rogers, the man who would become Captain America, was not subjected to an accidental burst of gamma radiation or the bite of a radioactive spider. Instead, he willingly enlisted and subjected himself to an experimental process for the creation of super-soldiers. His superpowers were deliberate and intended. However, the circumstances of Captain America’s enlistment into the army are, at best, questionable. After my chat with Maggie Koerth-Baker on bloggingheads, I got thinking about how the super-solider experiment holds up under the scrutiny of medical ethics. I’m not so sure that Steve Rogers gave his consent to the experiment in an informed and uncoerced manner.
For any medical research to be considered ethical it must adhere to basic standards. A global standard for medical ethics is the Declaration of Helsinki. Devised and published by the World Medical Association in 1964, the Declaration of Helsinki is a guiding framework for all medical research involving human beings. It has been revised over the years to meet modern needs, with the most recent and 6th revision being published in 2008. There are three points of the Declaration that ...
Caturtleday, with face-planty goodness | Bad Astronomy
I love biking, especially in Boulder. There are trails everywhere, and lots of fun wildlife. Whenever I’m out I see hawks, prairie dogs, red winged blackbirds, rabbits, and more. Sometimes even owls.
What I did not expect to see the other day, however, was a big ol’ turtle lumbering across the bike path! [Click the picture to testudinate.] For scale, I’d guess his (hers? Who can tell?) shell was about 30 cm across. He was trying to get to a creek off the path, I think, when I got this shot.
I switched to video on my camera, and happened to catch a moment that I’m sure would embarrass the turtle if it had access to YouTube:
Ha! Boom. Clearly, he shook it off and kept going. After I took this clip, he got a better look at how steep the creek bank was, changed his mind, and turned around. That process took several minutes; turtles are in no hurry.
As far as video quality goes, my apologies for a) the panting; I had just gotten off my bike to take the video so I ...
