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]
It's debatable whether the troubled World War Z signals the end of the ongoing zombie craze, but the film that started it all is much more clear: Danny Boyle's bleak, artful cult horror-drama 28 Days Later, which saw its US premiere ten years ago this weekend. From its iconic opening shots of an eerily abandoned London (set to Godspeed You! Black Emperor's brooding post-rock epic "East Hastings") to the frenzied chaos of its climax, Boyle's film -- a dark yet humanist tale of a world eviscerated by a frighteningly contagious epidemic of murderous rage -- reinvented and reinvigorated the genre that Romero built (though many insist its rabid, sprinting berserkers don't really count). And while sequel 28 Weeks Later with its heavyhanded Iraq War allusions failed to live up to the original (despite boasting one of the most viscerally terrifying opening sequences in modern horror), and 28 Months looks increasingly unlikely, there remains a small universe of side content from the film, including music, short films, comics, and inspired-by games.

"Why do parasites harm their hosts? Conventional wisdom holds that because parasites depend on their hosts for survival and transmission, they should evolve to become benign, yet many parasites cause harm. Theory predicts that parasites could evolve virulence (i.e., parasite-induced reductions in host fitness) by balancing the transmission benefits of parasite replication with the costs of host death. This idea has led researchers to predict how human interventions—such as vaccines—may alter virulence evolution, yet empirical support is critically lacking." Two papers demonstrate empirical evidence for related models predicting the origin of virulence: [more inside]
MIT scientist Dr. Todd Rider has developed a viral infection treatment that works by triggering host cell suicide when it finds the cell has been producing double-stranded RNA. Since dsRNA is the mechanism by which all viral infections proceed, but is not part of normal cellular function, the treatment seems both universal and safe. [more inside]
W. M. D.'s? There's been a lot of talk going on about bacteria infections in Iraq. Is it just common bacteria, or is the ground spoiled?
A quick HIV test is about to hit the US market. An HIV test that is easy to administer and provides results in 20 minutes has just been approved by the FDA. This is a big deal partly because almost 250,000 Americans are infected and don't know it. The ease of this fast-response test will help identify some of them.
The Demon in the Freezer An article by the author of The Hot Zone. " The water contained the whole molecules of life from variola, a parasite that had colonized us thousands of years ago. We had almost freed ourselves of it, but we found we had developed a strong affinity for smallpox. Some of us had made it into a weapon, and now we couldn't get rid of it. I wondered if we ever would, for the story of our entanglement with smallpox is not yet ended".
