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.

For millions of people around the world with essential tremor, everyday activities from eating and drinking to dressing and doing basic tasks can become impossible. This common neurological movement disorder causes uncontrollable shaking, most often in the hands, but it can also occur in the arms, legs, head, voice, or torso. Essential tremor impacts an estimated 1 percent of the worldwide population and around 5 percent of people over 60. Investigators have now identified a specific subregion of the brain's thalamus that, when included during magnetic resonance-guided focused ultrasound (MRgFUS) treatment, can result in optimal and significant tremor improvements while reducing side effects.
