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

SeaWiFS: The Effect of the Congo on the Atlantic
By monitoring the color of reflected light via satellite, scientists can determine how successfully plant life is photosynthesizing. A measurement of photosynthesis is essentially a measurement of successful growth, and growth means successful use of ambient carbon. Until now, scientists have only had a continuous record of photosynthesis on land. But following three years of continual data collected by the SeaWiFS instrument, NASA has gathered the first record of photosynthetic productivity in

Brain: The Inside Story's "Your Thinking Brain"
If there is one thing that makes you different from other animals, it is your extraordinary ability to think. Like other thinking species, humans don't just react to the world as it is: We reflect on the past, imagine what could be, and then plan ways to make our thoughts become reality. Our brain's advanced outer layer, or cortex, enables us to remember past events and predict the future consequences of our actions before we make decisions. We can think about thinking, and use language to excha

A Disintegrating Glacier
Recent satellite images have revealed two new icebergs floating off the Antarctic coast. The icy behemoths are fragments of the Ninnis Glacier. This NASA fact sheet uses text and remotely sensed imagery to describe the events of January 2000, in which a large tongue of the Ninnis Galcier broke off and split into two gigantic icebergs. The breakup of the Ninnis Glacier Tongue has important implications regarding the Antarctic Ice Sheet's potential response to global climate change and its effect

Multiple Coin Toss Model
The EJS Multiple Coin Toss model displays the result of the flipping of N coins. The result of each set of coin flips is shown by the image of the pennies on the screen and the complete results of the tossing experiment is shown on a graph of the cumulative probability of heads. The number of coins flipped, N, and change the "fairness" of the coin by setting the probability of a "heads" result, p, can be set via text boxes.

Pulley'ing Your Own Weight
Using common materials (spools, string, soap), students learn how a pulley can be used to easily change the direction of a force, making the moving of large objects easier. They see the difference between fixed and movable pulleys, and the mechanical advantage gained with multiple/combined pulleys. They also learn the many ways engineers use pulleys for everyday purposes.

May the Magnetic Force be with You
This lesson begins with a demonstration of the deflection of an electron beam. Students then review their knowledge of the cross product and the right hand rule with sample problems. After which, students study the magnetic force on a charged particle as compared to the electric force. The following lecture material covers the motion of a charged particle in a magnetic field with respect to the direction of the field. Finally, students apply these concepts to understand the magnetic force on a c

Atoms: Protons, Neutrons, and Electrons - by StudyJams
An atom is a tiny particle in matter, and atoms are made of protons, neutrons, and electrons.  Some matter, like your body or your book, is made of lots of different kinds of atoms, but elements are made up of only one kind of atom. Learn more about atoms with this cartoon animation from StudyJams.  A short, self-checking quiz is also included with this link.
