Read and understand · 1/2What did the researchers hope the device could eventually improve?

Read the answer and explanation

Medicine delivery after brain tumor surgery. The intended future use is improved delivery of medicine after surgery for glioblastoma.

Clue: MIT researchers designed an experimental brain implant combining a delivery tube and ultrasound. They hope it could one day improve medicine delivery after surgery for glioblastoma, an aggressive brain tumor.

Read and understand · 2/2What did the mouse experiment demonstrate?

Read the answer and explanation

An imaging agent spread farther with ultrasound. In the mouse experiment, the substance was an imaging contrast agent; treatment of patients has not been shown.

Clue: Ultrasound helped substances spread farther in gel and mouse tests. The mouse experiment used an imaging contrast agent, not a cancer treatment. The device has not been shown to treat patients.

Your turn

Explain the difference between the result in mice and the researchers' future hope.

See one possible answer

In mice, an imaging agent spread farther with ultrasound. The researchers hope a future version will improve medicine delivery after brain tumor surgery, but it has not been shown to treat patients.
