Stuff I forgot to mention about memory

And speaking of memory here and here, there's recent research I forgot to mention. Oh, the irony. (Damn! I sure hope someone comes up with a memory pill, and fast.)First up is a gene named Kibra. It's expressed in the hippocampus, and has been found...

Biological basis of aggression

Is it typical in animal species that there are significant, genetic differences between males and females in common behavior? The answer is yes, apparently, for fruit flies. And there is even a single gene whose slightly different forms in males and...

Alternative splicing

Not so very long ago it used to be that molecular biologists thought that for every protein in the body there was a specific gene, and every gene contained the instructions for making just one protein. Then, when the human genome was completely mapped...

What makes humans smarter than chimps?

Why have geneticists considered complete sequencing of the genomes of a variety of species so important? One reason (of many) is what we learn by comparing these other genomes with the human genome. And if you consider the genome of a close relative...
