So pleased that our findings from the 6.5-yr imaging survey I conducted with Cassini’s high resolution camera of the geyser basin capping Enceladus’ southern hemisphere made the cover of the Astronomical Journal! How sweet it is! [Scientists love this sort of thing ;-) ]

Dams make spawning salmon more prone to heart attack: UBC study

Reaching spawning grounds is hard work for salmon, and UBC researchers say fish forced to “sprint” through fast-moving water or other obstacles can suffer heart attacks.
The study found sockeye are more likely to die in the hours after being forced to swim fast and hard to make their way through turbulent waters below dams.
Researchers say so-called “burst swimming” creates severe stress that could lead to heart failure.
Female sockeye are especially prone, in part because females may be using more energy to produce eggs, hiking their sensitivity to other environmental challenges.
Biologist and lead author Nicholas Burnett says the study demonstrates how vital it is for salmon to have easy access around obstacles in the river.
The study is published in the latest issue of the journal Physiological and Biochemical Zoology.

It’s back-to-school season!  
Professors, I thought you might enjoy this bit from PhD Comics (via the TSP Editor’s Desk).

Nothing like holding a pure compound that you have just synthesized.
(bottom picture shows the structure of the synthesized compound)

The last steps in the synthesis involves hydrolysing the ester bond on the naphthalene ring and then coupling the carboxylic acid to a dipeptide chain.

These molecules are being synthesized and studied due to their anti-cancer activity shown in both lung cancer and malignant melanoma cell lines. Although past research is all ‘in vitro’, we hope to push for ‘in vivo' testing in the future.
