Cicadas can avoid predators by emerging in prime numbered intervals

Cicadas emerge from the underground only periodically. Depending on the species, that period will be 7, 13, or 17 years, which are all prime numbers. Why does this make sense?

Suppose there are some predators (like birds, and the Cicada Killer Wasp) that attack cicadas, and that the cicadas emerge every 12 years. Then the predators that come out every two years will attack them, and so will the predators that come out every 3 years, 4 years and 6 years. But according Mario Markus, “if the cicadas mutate to 13-year cycles, they will survive.

The other advantage is that cicada species with different intervals will rarely compete with each other for food.

Quote fight: meaning in life

On Sunday, Andrew Sullivan quoted this from an essay by Jennifer Fulwiler about becoming Catholic:

If everything that we call heroism and glory, and all the significance of all great human achievements, can be reduced to some neurons firing in the human brain, then it’s all destined to be extinguished at death. And considering that the entire span of homo sapiens’ existence on earth wouldn’t even amount to a blip on the radar screen of a 5-billion-year-old universe, it seemed silly to pretend like the 60-odd-year life of some random organism on one of trillions of planets was something special.

This is a woman who was an atheist until she married a Christian and had a baby. She was always racked with worry about the meaninglessness of life, so she read some Christian books and decided their standard arguments for Christianity were good enough for her.

Then yesterday, I read this post from Matt Haughey. He has a benign brain tumor and recently lost his mom to cancer.

I feel like the tumor scare has taught me to appreciate all the people, experiences, and things in my life and I’ve done my best to live a fuller life while I can. In 2012 I’m going to be doing a lot of things I’ve always wanted to do, and they will mostly involve travel to places all over the world (planning on Hawaii, New Zealand, Belgium, Yosemite, Italy, all in the first six months). A tumor taught me that life can be brutal and short and to relish our time here.

Of all the ways to demolish Fulwiler’s arguments against atheism — and most of them are pretty lame, if you read the whole article — I think this nails it best. If you can’t handle that a lifetime is all you get and that, yes, eventually your accomplishments will be washed away by the vastness of space and time, then I think you ask for too much.

Muscovy ducks get super-fast erections and have twisty vaginas — for rape and counter-rape

Female Muscovy ducks have spirally, squiggly vaginas that keep out undesired penises. For desired penises, they simply relax their muscles to allow entry. They have evolved this capacity while male Muscovy ducks have evolved 8-inch penises that get fully-erect in a third of a second.

Friends, duck sex is a high-stakes world.

Walking through a doorway makes you less likely to remember what happened in that room

You store your memories episodically. How does your brain mark the beginnings and ends of episodes? Perhaps by context? Perhaps by location? A new study suggests that walking through a doorway signals your brain to mark a new episode and that people are less likely to recall details after leaving a room.

Texas’ House of Representatives once unanimously passed a bill commending the Boston Strangler

To demonstrate how careless he thought the legislative process in Texas was, on April Fool’s Day 1971, Tom Moore Jr. introduced a resolution to commend Albert de Salvo.

This compassionate gentleman’s dedication and devotion to his work has enabled the weak and the lonely throughout the nation to achieve and maintain a new degree of concern for their future. He has been officially recognized by the state of Massachusetts for his noted activities and unconventional techniques involving population control and applied psychology.

Moore retracted the resolution after it passed unanimously. Albert de Salvo was the Boston Strangler.

We demand a vapid, condescending, meaningless, politically safe response to this petition

We the People is a web page that the White House created to let people create petitions that get official responses when enough people sign. Unsurprisingly, the official responses are disappointing and wishy-washy, like this one about the phrase “under God”, which was added to the Pledge of Allegiance in 1954.

Nevertheless, someone seems to have come up with a petition guaranteed to receive the consideration it demands:

Since these petitions are ignored apart from an occasional patronizing and inane political statement amounting to nothing more than a condescending pat on the head, we the signers would enjoy having the illusion of success. Since no other outcome to this process seems possible, we demand that the White House immediately assign a junior staffer to compose a tame and vapid response to this petition, and never attempt to take any meaningful action on this or any other issue. We would also like a cookie.

Sign the petition. Via Weigel.

It is hard to know how tall Jake Gyllenhaal is

David Rees becomes discouraged as he investigates Jake Gyllenhaal’s height. Incidentally, there is a website completely devoted to figuring out the heights of celebrities.

The CelebHeights.com discussion of Jake Gyllenhaal goes quiet for weeks at a time. Then someone posts an account of a recent sighting, or a photo of Gyllenhaal standing beside a celebrity of quantifiable tallness (like Xzibit), and then someone else counters that Gyllenhaal’s height is hard to calculate because “his body is like a peruvian guy (large oblong head, short neck),” adding “I should see him shaven” (?!?), and the whole thing flares up again. Any new piece of data, in the hands of the right maniac, can help a fact of the matter remain perpetually contested. This debate has been going strong for almost two years; is it any wonder that issues of slightly graver import—climate change, the theory of evolution, President Obama’s citizenship—are usually 5,000 percent overdebated?
