ScienceDaily: Do Migratory Birds 'See' The Magnetic Field?

ScienceDaily: Do Migratory Birds 'See' The Magnetic Field?: "These findings strongly support the hypothesis that migratory birds use their visual system to perceive the reference compass direction of the geomagnetic field and that migratory birds are thus likely to 'see' the geomagnetic field."

I bet they can see thermals too.

Genetic Code-Dependent: DNA Structure Also Crucial to Genomic Variation: Scientific American

Genetic Code-Dependent: DNA Structure Also Crucial to Genomic Variation: Scientific American: "Until recently, genetic variation between people, accounting for everything from differences in hair color to predisposition to illness were attributed to flaws in genetic coding known as single nucleotide polymorphisms (SNPs). But a new study argues that a genetic material's arrangement—along with changes in that DNA construct, such as insertion, deletion or rearrangement of segments of code within the genome—plays a more important role."
