Technique creates piezoelectric ferroelectric nanostructures
Cocaine and the teen brain: New insights into addiction
Researchers have developed a “soft template infiltration” technique for fabricating free-standing piezoelectrically active ferroelectric nanotubes and other nanostructures from PZT – a material that is attractive because of its large piezoelectric response. read more..

Cocaine and the teen brain: New insights into addiction
When first exposed to cocaine, the adolescent brain launches a strong defensive reaction designed to minimize the drug's effects, scientists have found. Now two new studies identify key genes that regulate this response and show that interfering with this reaction dramatically increases a mouse's sensitivity to cocaine. read more..
