Are We Alone in the Universe? -- Kerr 309 (5731): 88 -- Science
Wow. Science, the ultra-prestigious journal, has released a special public issue on the top 125 questions in science -- in honor of their 125th anniversary. They highlight 25 of those, including one of my favorite topics -- the question of human solitude. Alas, they don't explore the Fermi Paradox at all.
Be careful though -- I opened all 25 in tabs and my IP address was blocked as though I were some evil hacker. Go slow and read them one at a time.
