How do bones, isotopes, historic records, DNA and grave goods tell us about the dead? We check out the example of King Richard III, found in a parking lot! More »

Galactic rays

Galactic rays

Scientists have tracked a light beam that’s half-a-million light years long to a monster black hole and found that the hole and its disk of orbiting junk are spinning in parallel. Their new, supersize radio telescope promises more details on black holes at the center of most galaxies, including ours. More »

Shaking it up: Maverick scientist dies

Shaking it up: Maverick scientist dies

Sometimes, scientists feel the need to leave the lab and warn the public about onrushing hazards. Rowland warned about ozone, but others are warning about warming. Does scientific culture encourage or hinder going public? Does the helpful response to ozone depletion suggest we’ll succeed in confronting global warming? More »

Flight without wings

Flight without wings

Scientists thought wings were the first evidence of flight. But plenty of falling ants can glide back to “their” tree to avoid being devoured on the forest floor. If an ant’s brain and body are able to detect its position and change its flight path, is gliding the first flight? More »
