3:37 PM | Doorknobs (not just elevator buttons) going viral. Oh, my!
Almost immediately after the fearful news about elevator buttons, and with the world worried about the Ebola virus, the American Society for Microbiology has issued a press release decrying the dangers of doorknobs. As I wrote here recently, three doctors in Toronto wrote a little study about the bacteria they found on hospital elevator buttons. That study might foster a renewed yearning […]

3:30 PM | A Detailed Overview of Nanopore Sequencing
Because the sensor technology is so important [0], I recently mentioned why long read technology was such a breakthrough (it's an information theoretic issue [5]). For the past two years, we have featured here on Nuit Blanche at least three makers of sequencing technology that will change the course of how we do many things. Those outfits are: Oxford Nanopore Technologies (see [1,2, 6] ) Pacific BioSciences (see [4,5] )Quantum BioSystems (see [3] ) Nick Loman is one of the few people […]

5:41 AM | You Could Still Be Waiting
I owe a lot to this blog. This blog got me into science writing, from the first time I pitched the idea of writing about anything and everything science (but especially about science in popular culture) to Nature Blogs in 2010. Lucky for me, they accepted my pitch (I was at the time a slightly unfulfilled biomedical PhD student at WashU in St. Louis), and I've been blogging ever since. This blog guided me into a graduate degree in journalism. This blog helped... Read more

5:00 AM | Testable uniqueness conditions for empirical assessment of undersampling levels in total variation-regularized x-ray CT
This is the 2000th blog entry with a Compressive Sensing tag. Woohoo ! In the Map Makers, one can see that the sharp phase transitions can be used in many ways. One of the ways is to figure ut if a specifc mesurement essemble can be used efficiently. Another is to figure out if a specific technology can be improved. That discussion was somehow started for CT by Xiaochuan Pan, Emil Sidky and Michael Vannier in Why do commercial CT scanners still employ traditional, filtered back-projection for […]
