How is a change in taste protecting cockroaches?
A mutation in German roaches ?-- the most common species of the pest found in houses, apartments, restaurants and hotels -- has made sugar taste bitter to them instead of sweet.
Since most cockroach baits cover poison with a layer of glucose, a form of sugar, the change in palate enables them to avoid traps. Researchers found that seven of the 19 roach populations tested avoided sugar.
The roaches were collected primarily from the U.S. and Puerto Rico. The results were released in the journal Science.
n What new record did Daft Punk just set?
The musical duo's new album, "Random Access Memories," has broken the record for the biggest number of streams on Spotify in its first week in the United States.
Though Spotify wouldn't release the number of streams, Daft Punk did apparently beat the 8 million streams Mumford & Sons set with "Babel" last year. "Random Access Memories" is the fourth album from the Grammy-winning French group.
Daft Punk also set a Spotify record last month when its song "Get Lucky" had the biggest streaming day for a single track in the U.S. and the United Kingdom. Since its debut, "Get Lucky" has been streamed more than 27 million times.
