Breaking the seal

I always wondered about the concept of "breaking the seal" during a night of drinking. Apparently it's not a real effect. Beer makes you need to pee. Period. It's just that the effects don't set in immediately. The initial delay makes it appear that there's a seal that's broken after the first trip to the toilet. But it's just the onset of ADH surpression.

But how come you can hold your pee just fine until that first bathroom break, and then it seems you have to go constantly? First, it takes a little bit of time for alcohol to suppress ADH and for the kidneys to ramp up the water works. When you crack open your first beer, you may have some urine in your bladder already, but also some ADH in your system to keep things from getting out of hand. As you continue to drink, though, your ADH levels drop and your urine production increases. By the time your bladder has filled and you’re ready to go to the john, you’ve probably had a few more drinks. Your ADH is more suppressed and your kidneys are working at full tilt, so you’re going to have to go more often.

Any experts out there who can verify this?

A view from your shut down

The Daily Dish has been posting reader emails reporting on their " view from the shutdown ." If you think this doesn't affect you, or if you know all too well how bad this is, take a look at the growing collection of poignant stories. No one is in this alone except for the nutjobs in the House. I decided to email Andrew with my own view. I plan to send a similar letter to my congressperson. Dear Andrew, I am a professor of astronomy at the Harvard-Smithsonian Center for Astrophysics (CfA). The CfA houses one of the largest, if not the largest collection of PhD astronomers in the United States, with over 300 professional astronomers and roughly 100 doctoral and predoctoral students on a small campus a few blocks west of Harvard Yard. Under the umbrella of the CfA are about 20 Harvard astronomy professors, and 50 tenure-track Smithsonian researchers. A large fraction of the latter are civil servants currently on furlough and unable to come to work. In total, 147 FTEs

The Long Con

Hiding in Plain Sight ESPN has a series of sports documentaries called 30 For 30. One of my favorites is called Broke which is about how professional athletes often make tens of millions of dollars in their careers yet retire with nothing. One of the major "leaks" turns out to be con artists, who lure athletes into elaborate real estate schemes or business ventures. This naturally raises the question: In a tightly-knit social structure that is a sports team, how can con artists operate so effectively and extensively? The answer is quite simple: very few people taken in by con artists ever tell anyone what happened. Thus, con artists can operate out in the open with little fear of consequences because they are shielded by the collective silence of their victims. I can empathize with this. I've lost money in two different con schemes. One was when I was in college, and I received a phone call that I had won an all-expenses-paid trip to the Bahamas. All I needed to d

back-talk begins

me: "owen, come here. it's time to get a new diaper" him, sprinting down the hall with no pants on: "forget about it!" he's quoting benny the rabbit, a short-lived sesame street character who happens to be in his favorite "count with me" video. i'm turning my head, trying not to let him see me laugh, because his use and tone with the phrase are so spot-on.
