Yes we know of Magic Lantern (FBI) I think. Many of us are not from America so we do not worry but we have government problems too! Just like this! So we have ways to take care in danger of this.
1) Do not use Microsoft products
2) Use a popular Live CD for internet use
3) Keep properly encrypted archive for storage of files. Truecrypt or dm-crypt (with AES-256). With a long password of upper/lower case letters of numbers too and quotation/exclamation/expression/and more/ and no phrases.
2) Direct all internet packets through Tor
3) Only use HTTPS unless there is no choice. Get firefox and use Noscript plugin and Adblock plugin.
4) Make your initial connection to a Wifi router from long distance antenna to it so that you can use someone else internet connection then use Tor.
5) Do not give away details that identifying. You can say where you are from but do not say what city you are in. Do not say identifying things and more.
6) If you take photography of reaction then be sure to remove EXIF data from each picture. Use google to find EXIF data. Look for open source program. It is free and works not like fake pay program.
7) Be paranoid because you are chemist. Government are want to capture you because you top of food chain. They want to ruin you.

Tell no person what you do. Do not show them. No wife and no best friend. This is solitary work.
9) Love fellow bee or wasp because we only have each one of us and no person else.
10) Know that we are no perfect and can make mistake. Forgive for the science. The science must be first.
