Writer Michael Rosenwald called on Steven Welty to identify a strange smell in his home. Welty knows a lot about how air moves, and he knows about the stuff in moving air that can make us sick and die. From Popular Science: [more inside]
‘Free 10 Day Autumn or Winter Break: You may not win a Nobel Prize, but you could help find a cure for the common cold.’
"During the 2013-2014 flu season, according to the Centers for Disease Control and Prevention, only 46 percent of Americans received vaccinations against influenza, even though it kills about 3,000 people in this country in a good year, nearly 50,000 in a bad one." [more inside]
Ebola is nightmare fuel: a biological doomsday device conspiring with our bodies to murder us in uniquely gruesome fashion. It’s also killed fewer than 2,000 people. How has a virus with such a modest body count so fiercely captured the darkest corners of our imagination? - Leigh Cowart for Haziltt.
Is this a pandemic being born? [Google cache] The H7N9 (Bird) Flu Virus May Have Adapted To Mammals. The WHO is investigating. Four new human cases were identified late Tuesday.
"Experimental adaptation of an influenza H5 HA confers respiratory droplet transmission to a reassortant H5 HA/H1N1 virus in ferrets." After an extensive, months-long debate, one of two controversial papers showing ways the H5N1 "avian" influenza virus could potentially become transmissible in mammals with only 3 or 4 mutations was published in Nature today. The journal included an editorial on the merits and drawbacks of "publishing risky research" with regard to biosafety. The debate included an unprecedented recommendation by The US National Science Advisory Board for Biosecurity (NSABB) to block publication -- a decision they later reversed. (Via: 1, 2) Nature's special report has additional articles, including interviews with the teams behind both papers.
Locked up in the bowels of the medical faculty building here and accessible to only a handful of scientists lies a man-made flu virus that could change world history if it were ever set free.
In a hot lab in the center of Lyon, space-suited virologists want to create a superflu as contagious as H1N1 and as lethal as H5N1. Why? So nature doesn't get there first.
Is H5N1 flu transitioning to a human-to-human illness? Recent reports of familial clusters suggest that it may be, though there are certainly other possible explanations, such as families living in environments contaminated by virus-laden bird feces. On the other hand, it would seem that epidemiologists are growing increasingly interested in the possibility that these clusters are indicative of human-to-human transmissions. Further, the virus may be inching towards being asymptomatic, which isn't as good as it sounds: if people can carry the virus and transmit it to others without showing symptoms, it will be very difficult to impossible to tell who is a vector and highly difficult to control any emerging epidemic.
