The first sign of a biased dilettante is when they try to reduce biological phenomena to a single parameter that exhibits a straightforward linear effect. It’s true of IQ, and it’s also true of testosterone. This is an excellent video that discusses the complex relationship of testosterone levels to athletic performance.
Why, it’s almost as if there are a thousand parameters, each nudging performance this way or that, and acting in a combinatorial fashion!
I’ve been seeing a lot of excitement about this new discovery on an extrasolar planet: it’s got water.
“We know that water vapor exists in the atmospheres of one extrasolar planet and there is good reason to believe that other extrasolar planets contain water vapor,” said Travis Barman, an astronomer at the Lowell Observatory in Arizona who made the discovery.
That’s cool. Not at all surprising, but cool. I shouldn’t think it unexpected that H2O is found throughout the universe. I’ve also been seeing naive gushing about prospects for colonizing other worlds. They never seem to take the other parameters of this planet into account.
HD209458b is separated from its star by only about 4 million miles (7 million kilometers)-about 100 times closer than Jupiter is to our Sun-and is so hot scientists think about it is losing about 10,000 tons of material every second as vented gas.
It’s also 220 times the mass of Earth and has a surface (I’m curious about what kind of surface this gas giant has) temperature of about 1000°C. Since it’s 159 light years away, I won’t be taking a vacation there in my lifetime.
Well, when you put it that way, maybe I’d like to visit, just a little bit.
Correction: the latest buzz is about K2-18b, a rocky planet that is only 7-10 times Earth’s mass, and a mere 110 light years away. Compared to HD209458b, it’s a paradise practically right next door!
How to interpret the data they’ve got seems to be complicated.
Ingo Waldman, on the University College London team, explained that three different scenarios fit the data equally well: The atmosphere could be pure hydrogen with lots of water, or the atmosphere could contain hydrogen and nitrogen with just a little bit of water. Or a third option allows for a hydrogen atmosphere, a “tiny speck” of water, and high-altitude clouds or hazes that obscure the view.
Benneke and his colleagues throw in another option: liquid water in addition to water vapor. Their calculations suggest that it could rain in the mid-atmosphere of this world.
I don’t think that, after our quick jaunt for a vacation on K2-18b, we’re going to be breathing that atmosphere. H2 on Earth is present in less than one part per million, so that they’re even discussing how much hydrogen fills the skies of K2-18b is a little off-putting.
I made a stop to check on that lovely Argiope at the local Subway…and she was gone! I was very sad. So I made a trip out to our sludgy Lake Crystal to see if there was anything cool out there, and there was! There was a long girl hanging out in the grass along the shore.
Tetragnathid, obviously, a long-jawed orbweaver. How long?
I refuse to believe anything new will come of this. I suspect it’s going to be nothing but a remarketing of old strips.
Besides, if Gary Larson were to come out of retirement, or even reveal a cached archive of 25 years of secret strips, I’m pretty sure that would be so momentous it would have to be a prelude to the end of the world.
Might be worth it, though.
MIT seems to be having a bad day week month year, and new horrors keep tumbling out all the time. Thanks, Jeffrey Epstein, the one good you did in your life was to make corruption visible!
I’ve noted elsewhere that the rich get richer, and colleges with already massive endowments tend to be the recipients of more corrupt gift giving…so they inherit all the filth that comes with the filthy lucre. I suspect our small liberal arts colleges would be just as guilty if billionaires were trying to impress their peers by giving us money.
It’s because toxic masculinity is so ingrained in the culture that the staid ol’ NY Times can publicly say that “Having a penis thrust in your face at a drunken dorm party may seem like harmless fun”, and think that’s a good lead to a story about new testimony that confirms the accusations made against Kavanaugh.
I’ve never experienced that (I guess I attended the wrong kind of dorm party), but I’m a guy, I’d just find it inappropriate and disgusting. I can see how a woman would find it intimidating and insulting.
Hey! Hey, you! The University of Minnesota Morris is offering employment to an ecologist! Apply now!
(Special attention will be paid to anyone studying arachnid ecology…OW. OK, OK, fellow UMM biologists, I admit that’s not true, stop punching me. I’m not even on the search committee. See the description below for the real requirements: “broadly trained ecologists with expertise at the community, landscape, and/or ecosystem level who connect basic and applied ecology“. At least it doesn’t exclude arachnid ecology.)
Assistant Professor of Biology
University of Minnesota, MorrisThe University of Minnesota, Morris seeks an individual committed to excellence in undergraduate education, to fill a tenure-track position in biology beginning August 17, 2020. Responsibilities include: Teaching undergraduate biology courses including sophomore biodiversity with lab, ecology with lab, electives in the applicant’s areas of expertise, and other courses that support the Biology, Environmental Science, and Environmental Studies programs; advising undergraduates; conducting research that could involve undergraduates; and sharing in the governance and advancement of the Biology program, the division, interdisciplinary programs, and the campus.
Applicants must hold or expect to receive a Ph.D. in ecology or a related field by August 17, 2020.

After I was done protesting yesterday (lie: we’re never done protesting), it was late, it had been a long day, and I was too tired to cook, so I just picked up some wraps at Subway. The Sandwich Artist, who is also a student at UMM, said, “Hey, aren’t you really into spiders?” Yes, of course, my reputation is spreading, I guess. “There’s a big spider on the window over there, it’s been here for several days.”
Of course I looked.
I came back this morning when the light was good, with my camera. There she was, with a big orb web against the glass…Argiope aurantia.
It was impressive, especially since it’s been so chilly lately. I noticed the stabilimentum on the web are rather disorganized and scraggly — a kind of disordered denser mess around the center of the orb here. But she was huge and pretty, and most conveniently right at eye height. This was shot with just my 17-85mm zoom lens, nothing fancy, and I’m tempted to go back later with my good macro setup and get some closeups.
I was part of our local protest against the unmitigated evil of ICE yesterday. Several people spoke out with testimonials about people they know who are being deported, or of local raids. About two dozen people showed up.
It wasn’t enough. We’ve got crimes against humanity going on in our country right now, and do you really want to tell your grandchildren someday that you just stayed home and did nothing?
