Just listened to this weeks twiv, and the q dot dyes you mentioned are also used in electronics. There they are used as a ultra precise phosphor. In that application blue light from LEDs can be re-emitted as red, an... Read More
This episode: Some bacteria have been discovered that construct multiple types of magnet in their cells!
The human microbiome consists of thousands of viral and microbial species which inhabit the human body and have co-evolved with us to protect against pathogens, regulate organ function and supply nutrients and other factors essential for health. When these members fall out of balance, it can le... Read More
Vincent Racaniello accepts the Peter Wildy Prize for Microbiology Education, awarded annually by the Society for General Microbiology for an outstanding contribution to microbiology education. Filmed at the Dublin Convention Centre in Dublin, Ireland. Read More
Scientists have managed to reverse type 1 diabetes (T1D) in experimental mice by giving the animals an oral course of harmless gut bacteria that had been engineered to secrete the whole proinsulin autoantigen (PINS) and the immunomodulatory human cytokine IL-10 (hIL10). An international team led... Read More
Hello TWiV Doctors,
Two short things:
1. You probably already heard the TWiV shout-out you got on NPR's Morning Edition on Friday, March 30th. It's here: Read More
A microbiologist says hospital managers should take note of what Florence Nightingale said a century and a half ago - that open windows were the hallmark of a healthy ward.
Jack Gilbert, who works at Argonne National Laboratory, Illinois, in the US, puts forward the view that natur... Read More
What up Doc's?
I'm writing to voice my complete disagreement with the sentiments of Sven Urban, in his letter on TWIP 38, that you as hosts are prone to engage in a ‘degree of banter which is distracting'.
I'm sure Dickson does not mind being ant... Read More
Love the TWIPs! I'm a helminth user (25 hookworm for allergies), so your programs are fascinating!
Dr. Racaniello, after listening to TWIP 33 where you were discussing the history of your surname, I thought I'd give your listeners a way to remember you... Read More
The lead researcher of one of the controversial H5N1 avian influenza transmission studies in ferrets said today that he hopes scientists can resume work on the studies in about 2 weeks, after key groups have discussed the issues.
Dutch researcher Ron Fouchier, PhD, of Erasmus University, said... Read More
I guess it doesn't sting, which is a plus - clearly we need no more stinging/biting/blood-sucking creatures on this earth - but my real wonder is what's next, and why rat heart muscle? Read More
This transmission electron micrograph (TEM), taken at a magnification of 150,000x, revealed the ultrastructural details of an avian influenza A (H5N1) virion, a type of bird flu virus which is a subtype of avian influenza A. At this magnification, one may note the stippled appearance of the roug... Read More
For the first time, the vast array of bacteria in the human gut has been studied as a complex, integrated biological system, rather than a set of separate species.
The new approach, which reveals patterns that correspond with body weight, treats the human microbiome as a cohesive “supra-organ... Read More
The Society for General Microbiology (UK) publication Microbiology Today has a two page feature by Paul Duprex, Ph.D., Boston University, on Vincent Racaniello, Ph.D., Columbia University, and his popular podcast This Week in Virology. The article discusses Racaniello's use of new media to sprea... Read More
