System can 3-D print an entire building

  

The list of materials that can be produced by 3-D printing has grown to include not just plastics but also metal, glass, and even food. Now, MIT researchers are expanding the list further, with the design of a system that can 3-D print the basic structure of an entire building.

New data unearths pesticide peril in beehives

Honeybees create honey in their hive through the topped-out combs, and they keep beebread -- their food -- in the other combs.

Honeybees -- employed to pollinate crops during the blooming season -- encounter danger due to lingering and wandering pesticides, according to a new Cornell University study that analyzed the bee's own food.
