Real-time information about what's happening in our bodies at the cellular level could be crucial for fighting cancer and other life-threatening conditions. It would be incredibly helpful to know whether cancer drugs are reaching their targets or whether toxins are disrupting DNA in healthy cells. Now scientists at M.I.T. have created carbon nanosensors that they say can help answer those questions. The research was published December 14th in the journal Nature Nanotechnology. The researchers wrapped carbon nanotube sensors in DNA, and the coated sensors have been shown to be safe for living cells. The nanotubes emit infrared light. But that signal changes when cancer drugs or molecules that damage DNA bind with the sensor. By detecting the changes in signals, such as intensity and wavelength, the researchers have shown they can determine just what's happening to cells in real-time.
AI explanationShows the answer. Tap to open.
Printed "heeling", the speaker says "reaching"

Explanation: In the audio you hear "reaching their targets". They start with different letters, but end the same.

Printed "revels", the speaker says "nanosensors"

Explanation: Here the speaker says "carbon nanosensors that". The printed word starts with a different letter and the spoken word is much longer.

Printed "pantaloons", the speaker says "nanotubes"

Explanation: The speaker says "the nanotubes emit", not "pantaloons". Pantaloons makes no sense here, so click it.

Printed "acceptably", the speaker says "intensity"

Explanation: Listen for "such as intensity and". The first letters differ and the endings differ, so follow your ears.

"Nature" matches the audio

Explanation: "journal Nature Nanotechnology" is a familiar phrase in the text. It matches the audio exactly, so do not click it.

"DNA" matches the audio

Explanation: Exactly "disrupting DNA in healthy cells" might look like a trick. The speaker says it as printed, so do not click it.
