- 'Bout time. In the face of ongoing opposition, climate scientists are using stronger language to discuss global warming.
- She's crossing the streams! Jen McCreight brings science blogging to Savage Love to address the mystery of the G-spot.
- Wait till you find out what works best. The next breakthrough in mosquito repellant might work by overwhelming the bloodsuckers' antennae.
