What would happen to you if you shrank to 1 inch high? And more

How can ants lift such huge things? How did T. rex move? Why do we find squirrels cute? Could the alien from Alien really exist? What should you do if you are faced with an ant radioactively blown up to elephant size?

If you’re intrigued, check out It’s Alive! by Michael LaBarbera on Amazon, part of the Chicago Shorts series (it’s just 52 pages) from the University of Chicago Press. I normally never advertise things, but this merits an exception because it’s cool science in small bites, a lot like this blog. Well, except that the author is a respected professor at a prestigious university, so you have to pay $3 for that extra 40 years of knowledge.

And yes, the author is also my father: this is the guy who gave me my love of science. If you’re at all interested in the physics of biology and behavior, or in what really killed the rampaging giant octopus in It Came from Beneath the Sea (it’s not what you think!), it’s definitely worth a look.

A heartwarming story, sort of

A few weeks ago, one of my officemates and I were discussing how dangerous it is to be a baby bird when he mentioned that among the creatures that will eat young birds—rodents, deer, ants, slugs—are Western Scrub Jays. “I’ve seen them hunt down and eat young fledglings,” he said. So when, this weekend, I saw a scrub jay pecking at something small and cheeping, I dropped my grocery bags and ran.

The victim was a young fledgling, probably no more than a day or two out of the nest. He cowered on the ground when I reached him. I looked around for his parents, but although there were many spectators peering down from the branches—European Starlings, Chestnut-backed Chickadees, Bushtits—none of them seemed upset. They were there to watch a show, not defend a baby. And although I wasn’t sure what species the fledgling was, I could tell he was too big to be a chickadee or a Bushtit, and he lacked the long-faced look of young starlings.

Scrub jays are smart birds, and I knew if I left the fledgling there, he would go right back on the menu. Too, from the way he huddled and didn’t move, I worried that he was injured. I took him home.

In praise of Canada Geese

Canada Goose in flight.

Canada Goose in flight.

I volunteer with an education program at a prison. Clear sight lines from the guard towers being essential in a prison, there isn’t much cover, so there aren’t many birds. I’ve seen House Sparrows and Mallards and pigeons. The inmates report that seagulls are prone to getting caught in the barbed wire that tops the fences. The inmates don’t have much sympathy for the seagulls, since they’ve had to try to protect Mallard ducklings from marauding seagulls in the past, generally unsuccessfully.

Recently I saw a Red-winged Blackbird and a Common Starling both trying to claim the same bit of fence as their own. I can’t imagine why they wanted the fence (perhaps so that they could listen in on our class and learn how to solve “3 is 60% of what?”, too?), but it was exciting to see them. Serious birders have state bird lists; I don’t have that, but I do have a mental prison bird list, and both of those species were firsts.

Getting a (science) PhD is not the most terrible idea in the world

It seems as though, every few months, an article called something like “Never EVER Get A PhD, It WIll Ruin Your Life Forever!!” is published. It is then met with various response articles, either of the “Yes It Ruined My Life Too” or the “Actually PhDs Are Completely Worthwhile, You Jerks” varieties, and fades into obscurity just in time for the next article to come out.

I really don’t want to be another one of those response articles, but I think it’s worth writing a few things here that I generally don’t see mentioned in the PhD hate/lovefests. If you don’t care about PhDs, here is a fluffed-up Anna’s Hummingbird so this post isn’t a total loss.

Genetics is complicated: mouse edition

Genetics is complicated. I have taken courses to this effect; I have taught the concept in Introductory Biology. Mendel’s peas with their neat logical Punnett squares were a lucky rarity—each trait governed by just one gene, each of those genes on a separate chromosome. The genetic basis of the vast majority of traits is far more complex. If the genes involved aren’t physically linked (called “linkage disequilibrium”) then they are pleiotropic (influencing many different traits at once), or epistatic (modified by other genes), or simply so subtle that their effects disappear in the noise of environmentally-caused trait variation. Relating traits to genes is hard.

I know this; I understand it; but until recently, I had never actually seen it. Then my pet mice decided to give me an object lesson in genetics.

What happens when you think you have all female mice, but you actually have mostly females and one male?

This happens. (Incidentally, doesn't this look like a mouse version of the Canadian flag?)

This happens.

Another freelance science mouse

A few months ago, my labmates who study chipmunks enlisted the help of one of my pet mice to test-run a chipmunk-monitoring device that they are hoping to use in the field this summer. That went well, and now they’re calling on another one of my mice for a simpler test: to see how long the glue they’re planning to use will keep their device attached to rodent fur. They want glue that will stay attached long enough for them to get good data, but not so long that the monitor becomes a permanent part of a chipmunk’s life.

Since chipmunks spend a lot of time in burrows, we chose my most burrow-loving mouse, who likes to spend all of his time hiding underneath things. He was not pleased to be forced out into the open.

So far he hasn’t seemed to care a bit about the chip. However, he is quite annoyed that I now dig him up daily to check whether it is still attached. He’s not really a people mouse.

PLEASE just leave me alone.

PLEASE just leave me alone.

Much better.

The incredible story of the Black Robin

This is the Black Robin (Petroica traversi), a species found only in the Chatham Islands, New Zealand:

This was the total world population of Black Robins in 1980:

Five birds. That’s not great—and it gets worse. Guess how many of those were adult females?

One.

Almost any conservationist would tell you that this was a hopeless situation. You can’t restart a species from one female—especially when that female is a whopping eight years old already, in a species that generally lives four years.

Dinosaurs probably looked just as awesome as you think they should have

When you’re little, you play with toy dinosaurs all bright red or blue or painted spotted with many colors. You fill coloring books with purple velociraptors taking down plaid apatosaurs. Then you get older and learn about camouflage; and you watch nature documentaries of brown felines taking down brown gazelles in tall brown grass; and—zebras notwithstanding—you start to think that probably dinosaurs weren’t plaid after all.

Well, buck up! They—at least some of them—probably did look really awesome.

Research is personal (two quotes)

Quote 1 – preface to reviews accompanying the rejection of my application for a grant

“In reading the reviews, please keep in mind that the reviews are… [not addressed] to you, the investigator… Some reviews may contain irrelevant, non-substantive, erroneous or ad hominem statements.”

I love that last sentence – it’s both horrible and hilarious. I would probably find it less hilarious if there had actually been any ad hominem attacks in the reviews I received, but my reviewers were all professional. I can easily imagine how there might be less professionally objective reviews, however.

"This applicant is, personally, the sole reason why we haven't solved deforestation and climate change! Not only shouldn't we give her money, we should actually steal money from her when she isn't looking! Come on, Review Committee, who's with me?"
