Oldest tooth filling may have been found
We all know the drill: Slip up on your regular brush-and-floss routine, and you may end up at the dentist's office with a cavity that needs to be filled. But what people did about their toothaches thousands of years ago?
Scientists in Italy have discovered what may be the earliest evidence of therapeutic dentistry performed on a human.
A study published in the peer-reviewed journal PLOS One reports the discovery of a beeswax filling on the left canine of a 6,500-year-old human jawbone from Slovenia. It is housed at the Natural History Museum of Trieste, Italy.
NASA's last space shuttle on nostalgic flight to retirement home
The space shuttle Endeavour began its final aerial show on Wednesday, thrilling spectators across the southern United States before completing the first stage of its transcontinental voyage in Houston.
After a two-day delay due to unfavorable weather, Endeavour began its flight from Kennedy Space Center in Florida to Los Angeles, where the now-retired spacecraft will be displayed.
Endeavour, along with Discovery, Enterprise and Atlantis, became museum pieces after NASA ended its 30-year shuttle program in July 2011.
Los Angeles prepares for space shuttle retirement
Los Angeles County, California, isn't like outer space. It doesn't have a lot of room for a space shuttle to move around.
The numbers say it all: Some 265 trees, 202 street lights, seven power poles, six traffic lights, two overhead signs, and two railroad crossing arms have been removed from the 12-mile route that Space Shuttle Endeavour will travel next month to its retirement home at the California Science Center, according to the Los Angeles mayor’s office.
While engineers finished their work making the shuttle safe for public viewing, city workers in California have been busy making the streets of Inglewood and Los Angeles suitable for an orbiter to pass through.
