SCIENCE SATURDAY IS FINALLY BACK!

Today I'm going to continue with the gene linkage theme from last time and talk about lod scores. Prepare for some possible (probable) boredom-- but if you ever take a genetics course (or, should it strike your fancy, go into genetics as a career), it will be heckly useful to you.

Lod stands for Log of Odds. It ( Read more... )

GENETIC LINKAGE EDITION!

The concept of genetic linkage is tied in with the concept of genetic recombination (i.e. crossover). During meiosis, homologous pairs of chromosomes trade DNA by crossing over each other and swapping. This is after replication; where you've got two X-shaped chromosomes in each pair.

In honor of They Day, I'm posting videos of some of TMBG's science-y songs today.

"Mammal"
(There doesn't seem to be an official video for this song, so I picked the best looking fan video.)

I definitely recommend that you follow the instructions at the end and watch all the videos. Someone made a site to display his videos in an easily navigable way, so go to wonderingmind42.com to see them all.

Why must you be so elusive, Time?

This is just a quick post about why Science Saturday is late again.

Homework.

That is why.

They'll probably be late. I'll do my utmost to get them in on time, but if I'm a few days late, please bear with me. It'll happen more often than not.

It's Wednesday.
I'm sorry.
But it was fortuitous that I couldn't get to it till today because of some AWESOME SCIENCE NEWS.

CHECK IT OUT: The Large Hadron Collider was SUCCESSFUL today! Heckyes!

Promised part 2: Science History Time!

The Mars Climate Orbiter was launched in 1998. It was, as I'm sure you guessed, going to circle around Mars and gather ( Read more... )

I'm at college now, and in the bookstore they had the May-June issue of American Scientist. There was a really interesting article in there about having words on the tip of your tongue (called the "tip-of-the-tongue state," which I imagine is a liminal state because you're caught between the concept and the word) and what this has to do with the ( Read more... )
