NOAA National Hurricane Preparedness Week    # 7316     As a native Floridian who has spent roughly 50 of his nearly 60 years living in the Sunshine state (with 15 of those years living aboard a variety of boats) – I have an understandable interest (read: `morbid fascination’) with hurricanes.   During much of my youth the Atlantic basin was in an active hurricane cycle, which provided me with an early education on these storms.   Here […]

11:10 AM | A closer look at vitamin injections
Vitamins are magic. Especially when they’re injected. Roll up the sleeve, find a vein, insert a needle and watch that colourful concoction flow directly into the bloodstream. It may sound somewhat illicit, but that person infusing it is wearing a white coat, and you’re sitting in a chic clinic. There must be something to it, [...]

7:48 AM | Quote antivaccinationist Hilary Butler: Non-vaccinators are the “new Jews”
I’ve never been able to figure it out. Antivaccine zealots seem to have an intense love of Nazi analogies and comparing those supporting science-based medicine to Nazis. While from a strictly nasty point of view, I can sort of understand the utility of such analogies to demonize one’s opponents. After all, to political extremists of…

2:35 AM | Broad Street chump
We now revere John Snow, the father of modern epidemiology, for his brilliant work in tracing (and eliminating) the source of a cholera epidemic. Back in the day, though, Lancet founding editor Thomas Wakley was, to put it mildly, not a big fan. Here is John Snow’s obituary, published in Lancet on June 26, 1858:“This well-known physician died at noon, on the 16th instant, at his house in Sackville Street, from an attack of apoplexy. His researches on chloroform and other anaesthetics were […]

Danger has threatened our lives since the dawn of time. Nature has given all creatures mechanisms to ward off and fight danger and keep safe.

Credit NIAID   # 7314   Helen Branswell has the details today on a new study which appears in the Journal Science, that looks at the ability of the avian H7N9 virus – recently emerged in China – to infect and transmit among ferrets.   Ferrets are considered a reasonable mammalian substitute for humans when testing respiratory viruses because their lung physiology is similar, and because they cough and sneeze when infected, very much as humans do.   […]
