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
Brain: The Inside Story's "Your Changing Brain"
Your brain began forming before you were born, building the intricate network of neurons that help you survive in the world.

The Politics of Religious Dissent in Contemporary Saudi Arabia
Since the events of 9/11, Saudi Islamists have attracted considerable attention. However, given the opacity of the Saudi Kingdom, very little is known about them.

Mt. Pinatubo 10th Anniversary Perspective (Stills)
This recent false color Landsat-7 image, from January 2001, shows Mt. Pinatubo as it stands today. The caldera is seen in the middle of the image, underneath clouds. Ten years after the blast, vegetation is re-growing on the slopes of the mountain (in green.) Streams of mud, called lahars, (resulting from ash from the eruption mixing with water- seen as the lighter sediment) continue to flow down the sides of the mountains, as well as channels of water (darker streams). However, as vegetation gr
What Students Want: Teaching from a Student's Perspective
Teachers often make assumption about what motivates, excites or frustrates their students. But how do students themselves view teaching? This video is from college students, but has applications for other levels as well. This 1:37 video is best used as an example of what teachers might do to improve by asking students who have left their classroom for a few years what helped them the most. I have done this and it is most valuable.
How Many Kisses Do You Want Tonight? Read-Aloud Online Picture Book
How Many Kisses Do You Want Tonight? by Varsha Bajaj---From bear to butterfly to snake, 10 animal parents--some moms, some dads--ask their little ones the title question: "'How many kisses do you want, young fellow?'
