DO Fear the Reaper

Possibly-Apocryphal Biological/Chemical Disaster-Filter: years ago, a friend told me about a haunting, peculiar biological (or chemical) laboratory disaster. I've always wondered whether she was yanking my chain. She's passed away, but I'd like to know if anything remotely LIKE the disaster she described has ever occurred (in a nutshell: "some deadly skin/respiratory agent kills everyone working in a lab facility instantly"). Literally-gory details within. [more inside]

WVa water crisis - who came first?

Which facility was constructed first, the WVa American Water treatment plant, or the Freedom Industries chemical storage place? In other words, did WVAW "come to the nuisance," or did Freedom choose to build upstream from the water plant? what dates was each facility constructed? (and if Freedom came subsequently to WVAW, did the latter protest at the time?)

NYC subway trains stink, mold?

I feel sick every time I get on to nyc subway trains. The N train is constantly stinky like urine and mcdonalds and feet, that triggered my multiple chemical sensitivity badly. I noticed 7 train usually have very fresh air which does not trigger my symptoms, as well as #6 train. R train is much better than N train, and E train is much better than F train. I want to know what caused these nasty stinky trains? Are all odor caused by mold? Btw: I can't tolerate PATH smell as well. I'm so confused people in these trains seem do not feel anything. Any information or comment are welcome.

The most efficient way to kill ivy growing on the side of a house?

Hello, I've got a mass of ivy leaves growing along the side of my house, digging its way into the brick and poking through windows at some points. The ivy is growing from a "bed" with a couple of other plants (my terminology may be off, I'm not much of the gardening type). I want this ivy to die. The other plants that are growing near it are acceptable collateral damage. What I'm looking for is basically the chemical equivalent of a flamethrower. I'd like to buy something I can dump all over the roots and then come back a few days later to find all of the ivy growing on the side of my house dead.

What did I eat and what do I do about it?

I just had a bite of a popsicle that tasted like saltwater and/or salty chemicals. The bite reached the back of my throat and then I spit it out and rinsed/gargled my mouth with lots of water. I can still taste salty-chemical-somethingness at the back of my throat. Now what? [more inside]

Please help me give advice to my brother about a chemical engineering phd

I'm worried my brother might be making the wrong decision about his degree. He has a fellowship and is well on the way to getting a phd, but he is thinking of stopping at a masters so he can get a job. The reasons he gives seem naive to me, but I don't know anything about this field. I'm worried he's going to end up being bored and unfulfilled because he's focused on short term goals. [more inside]

Detergent-induced feline narcolepsy

When we change the duvet cover on our bed, Pusslikeso immediately dives under the covers and basically becomes comatose. She can't wait, she runs into the bedroom as soon as we start and jumps up while we're changing the bottom sheet (so she often almost gets herself made into the bed). What chemical could she possibly be reacting to? [more inside]

Help invigorate a bunch of tired biochemists!

The music that everyone at my lab bench most enjoys working to is stuff like Daft Punk, The Chemical Brothers, Justice, etc etc etc. Particularly good are seamlessly mixed live sets. Can anyone recommend any easily obtainable sets from these artists, or similar artists that mightn't be on our radar? We've already exhausted Alive 2007, amazing as it is. The only caveat is no naughty words; everyone was pretty abashed when a senior academic walked by just as SUCK MY DICK / AIN'T THAT SOME SHIT was blasting.
