Blog Comments

Kinetica Online is pleased to provide direct links to commentaries from our senior editor Dr. Steven Pelech has posted on other blogs sites. Most of these comments appear on the GenomeWeb Daily Scan website, which in turn highlight interesting blogs that have been posted at numerous sites in the blogosphere since the beginning of 2010. A wide variety of topical subjects are covered ranging from the latest scientific breakthroughs, research trends, politics and career advice. The original blogs and Dr. Pelech’s comments are summarized here under the title of the original blog. Should viewers wish to add to these discussions, they should add their comments at the original blog sites.

The views expressed by Dr. Pelech do not necessarily reflect those of the other management and staff at Kinexus Bioinformatics Corporation. However, we wish to encourage healthy debate that might spur improvements in how biomedical research is supported and conducted.

A Bargain Made

Blogger Ananyo Bhattacharya at The Guardian 's Notes & Theories blog wrote that conventional thinking in science policy, which promotes a utilitarian view that research should be at the heart of sustainable economic growth and should serve the public interest, can result a dramatic undervaluation of basic research. S. Pelech comments that especially in the last 50 years, governments throughout the developed world have steadily built up their basic research capacities in the life sciences in universities, hospitals and government laboratories, but the translational gap between basic and applied research appears to have continued to widen. He explores the various reasons for this disconnect. Read More...

Dissecting DIY Letters of Rec

Blogger Damn Good Technician is irritated that research supervisors sometime instruct their trainees to help prepare their own letters of reference. S. Pelech points out that when he requests such a draft letter, it is because it often provides a useful self-assessment by the person for their own benefit, so they can appreciate the amount of time that it takes to produce a good letter, and to improve the prospects of including points that might have over looked that could benefit the individual.

Cancer-causing mutations yield their secrets

Three recent papers published in Nature have shed new light on how mutations in the isocitrate dehydrogenase 1 (IDH1) gene cause brain cancer and leukaemia. IDH1 acts early in the citric-acid cycle to produce ATP, and the IDH1 mutations associated with cancer inhibit the pathway, but also cause production of a bioactive metabolite called 2-hydroxyglutarate. S. Pelech notes that mutations of IDH1 and IDH2 are amongst the most common in human cancers and may be one of the contributing factors to the observation that tumour cells commonly demonstrate higher rates of glycolysis and anaerobic production of ATP from glucose, which is known as the Warburg Effect.

Cuts at AstraZeneca

The Wall Street Journal reported that AstraZeneca announced that it will be eliminating 7,300 jobs by the end of 2014, which will bring the company's total jobs cuts during the past five years to about 30,000. S. Pelech comments that the AstraZeneca's announcement is symptomatic of recent trends with several other major pharmaceutical companies, and it is likely that many of these jobs will ultimately be re-directed to emerging opportunities in Asia. He questions the wisdom of AstraZeneca instead to forge virtual alliances with small biotech and university-based researchers to help fill its drug pipeline. Read More...

Hold the Arsenic

Rosemary Redfield at the University of British Columbia posted a paper on ArXiv that refutes NASA astrobiologist Wolfe-Simon's conclusions that described a bacterium that seemed to grow on arsenic and incorporate it into its DNA. S. Pelech provided a summary of many problematic aspects of the Wolfe-Simon NASA study in a previous commentary in GenomeWeb's The Daily Scan (url: http://www.genomeweb.com/blog/arsenic-yes-please).
