Here's how you should format journal titles:
* Italicize the journal title: *Nature*, *Science*, *The New England Journal of Medicine*
* Capitalize all major words in the title.
There are a few exceptions:
* Some style guides may have specific preferences for how journal titles are formatted. Always check the specific style guide you're using for their rules.
* If you are writing by hand, underlining is a common way to denote italics, but this is not necessary for digital text.
