Scientific Linux would have been my first suggestion. Failing that anything Red Hat, Debian or Arch based might be good choices. Because they are distros that serve as the base for a lot of other distros and have huge software repositories, including a lot of scientific applications!
If you want something stable, CentOS (RHEL based and also used as the base for scientific Linux) might be a good choice. Or Debian stable.
If you want something more bleeding edge - perhaps Debian testing, Ubuntu/Mint, Fedora, or perhaps something Arch based?!
I think the scientific community usually go with Red hat based distros (RHEL, Fedora, CentOS).
Scientific Linux isn't going to continue, so they won't release a version 8 since they are going to contribute to the CentOS project instead maintaining Scientific Linux. There's also still CERN Linux.
Also a question, how hard is it to do some of your own research? Since all of the answers you have gotten here have done exactly that for you. While you could have done it yourself by going to a search engine and typing in what you are looking for. Just my two cents.
