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
Closeup of Solar Tadpoles with time tags
Here is a close-up view of dark tentacles or tadpoles moving towards the solar surface in this solar flare of April 21, 2002 seen by TRACE. One theory proposed in this press release is that they are due to voids created by magnetic reconnection in the flare. This version of the visualization displays the instrument clock time tags.

"So what is Physics anyway? Simply put, Physics is the study of energy. Okay, that's a short answer, what does that mean, the study of energy? Well, we can break down Physics into several units one of them is motion. You're familiar with motion, concepts like speed and velocity. Forces, physical forces include things like gravity and friction. Physical forces are energies also carried in the form of waves and when we talk about waves we're typically talking about things like sound waves and ligh
Newton's Laws of Motion
This 4:20 minute long video shows the three main laws of motion developed by Sir Isaac Newton and is down with excellent graphics.
The first law of motion, inertia, is when an object will not move or else move in a straight line unless an unbalanced force is on it. The second law of motion is the force mass and acceleration; acceleration fo an object depends on the mass and magnitude of the force. (force=massxacceleration) The third law of motion is the law of action and reaction. In
