Cold Equatorial sea surface temperatures across the Pacific indicate La Nina weather pattern, typical of less stormy and warm conditions in the far southeast US. The division between this warmer air and colder air to the west may result in a stormy pattern for the mid west. Image data courtesy of NOAA.

Ultrasound Doppler of femoral vein for finding  deep vein thrombosis or DVT.
Aligned amino acid sequences of various individuals. The amino acids were derived from their three bases in the genetic code and seen in a DNA sequence. This type of alignment is useful in determining the relatedness of individuals. In this case the sequences were derived from the ribosomal genes of a somewhat obscure fungus not known to be of any commercial, industrial or other value.
