Here are my Research Blogging Editor’s Selections for this week.

How about some Valentine’s Day science on this Valentine’s Day?

• First, from Melanie Tannenbaum at PsySociety: are love and hate really all that different?
• Psych Your Mind hosts guest blogger Maya Kuehn who has all the research on speed dating in one handy blog post. The best advice? “Be selective! They’ll like you more if you don’t show interest in everybody.”
• What happens in the brain when you’re in an intense, long-term romantic relationship? Jordan Gaines explains a new study that used fMRI to address this question. Your love is my drug.

While you’re at it, check out this post I wrote last year for The Guardian: Valentine’s Day dating tips from lovestruck scientists.
