A very scary, yet eye openning, article appeared in The Chronicle of Higher Education recently. The article, which is titled “The Future of the Ph.D.” discusses the downfall of the coveted tenure faculty position, and how only 30 percent of of the teaching faculty are tenured and tenure-track academics.
The author also highlights the dismal plight of female graduate students who dare to succumb to their maternal instincts during the course of their graduate studies.
The article finishes with the thought provoking question “Is the Ph.D. worth saving?”
I’m not sure. How about you?

What do you get when you cross a yeast and first year biology students?
Apparently, a very cool undergraduate course and significant scientific innovation!
UC Berkeley students who are lucky enough to be enrolled in the university’s entry-level biology course are being exposed to a discovery-based learning curriculum that gives them hands-on bench experience and has resulted in the discovery of a novel technique published in the current issue of Genetics.
Under the mentorship of University of Massachusetts Amherst geneticist Jacob Mayfield, students devised a technique for testing the consequence of variant human gene alleles by moving them into yeast cells. Once swapped into yeast, colony growth was be compared to reveal functional differences.
The technique was used to compare allelic differences in the Cystathionine-beta-synthase (CBS) gene, created by site-directed mutagenesis. Deficiencies in the gene causes homocystinuria which can be rescued by vitamin B6 treatments. However, only some individuals respond to vitamin B6 treatment while others do not. Using the yeast metabolic profiling technique, researchers were able to ascertain which individuals, (based on their CBS sequence), would respond to the B6 treatment and which would not.
Sounds like a winning program to me!
