Listen to the first notes of an old, beloved song. Can you name that tune? If you can, congratulations -- it's a triumph of your associative memory, in which one piece of information (the first few notes) triggers the memory of the entire pattern (the song), without you actually having to hear the rest of the song again. We use this handy neural mechanism to learn, remember, solve problems and generally navigate our reality.

Scientists have created a new nanoparticle that could make ultrasound-based cancer treatments more effective and safer, while also helping prevent tumors from coming back. To make the therapy even more powerful, the scientists also attached a potent chemotherapy drug to the peptide on the nanoparticle's surface. The ultrasound physically destroys the tumor, and the drug helps eliminate any leftover cancer cells that might cause the tumor to return.
