Using Dermatoglyphics from Down Syndrome and Class Populations to Study the Genetics of a complex tr
Dermatoglyphics is the study of epidermal ridges on the hands and feet. Ridge patterns and counts develop prenatally, are inherited, and show quantitative variation. This exercise introduces the preparation and interpretation of finger and palm prints for quantitative analysis. The techniques are simple, inexpensive, and can be adapted as an exercise on genetics for beginning or advanced students. Palm prints from individuals with Down Syndrome serve as a population sample to statistically test
Lighting Up: Analysis Of Yeast RAS Genes Using A Chemiluminescent Southern Blot Procedure
Genomic and plasmid-encoded RAS2 genes from Baker's and brewing yeast strains will be analyzed using a shortened Southern blot procedure employing chemiluminescence. Unique parts of this procedure are the gravity-driven "upside down" transfer and a rotisserie-like hybridization oven, which greatly facilitate shortening the transfer time to 45 minutes and the hybridization step to 60 minutes. Chemiluminescence obviates problems associated with radioisotopes without sacrificing sensitivity: the pl

1.8 Reflecting on definitions of ‘abnormality’ The main thing to remember is that the way that ‘abnormality’ is defined will have consequences for the method of identification. It will also impact on people's expectations of their future development. For example, we discussed the way that dyslexia is defined in relation to a person's IQ. Does that mean that if someone has a low IQ and an even lower reading age we should adjust our expectations of what that person can achieve with help, or let IQ influence how much help is offered

This 5:22 long video shows Uranus as a huge, icy giant, Uranus is one of the system's great mysteries. Frigid temperatures, powerful ice storms and a wobbly and upside down ring system make up just a few things that puzzle scientists today. A very good overview that uses graphics and NASA photos.
Latitude and Longitude
This video shows the Latitude and Longitude lines on a globe with Washington DC. Latitude lines run east to west and its zero degree is the equator. Longitude lines run north to south and has a prime meridian in Greenwich, England. To make latitude and longitude lines more accurate you can split the degree into Minutes and Seconds. The exact measurements for Washington DC is 38 degree 53'22''

Where the Shape of the Egg Comes From?
The shape of the egg is postulated to be the consequence of opposing forces relative to the location of perspective of points that define the spaces of its' contents. For example, net velocities of motion of light emitted in two planes plus the velocity of motion of its' source would be expected to be decreased in the case when the direction of the light beam is opposed to the direction of motion to cause the blunt edge and increased when it aligns with the direction of motion of its' source t
