Wild America: We might have lions and elephants in North America soon! (Slate also has an article on it) Perhaps on our military bases? Nature has an article that bloggers are talking about that says that military bases are often better for conservation than national parks? I haven't read it yet, because access is restricted, but I will definitely have to read it before I can believe it.

Working Too Much: can be bad for your health! So next time your boss asks you to stay late, you can say you can't for medical reasons. That may just further convince your boss or colleagues that you are lazy-- apparently most people think other workers underperform. (But as the WP article I linked to earlier this week discussed, that is actually more stressful for workers than being overworked.)

Another thing that's bad for your health: exams. Apparently the stress of exams is making students drink more. (Or is that just an excuse for students to drink... along with about anything else they can think of...?)
