Naya blood test: Cancer ko pehle hi pakad lo, yaar!

Arre suno, ek naya blood test aa gaya hai, jo cancer ko pehle hi pakad lega! Han Zhang ki team ne DNA nanostructures aur Crispr ki jodi se ek chamakdaar sensor banaya hai, jo microRNAs ko dhoondta hai. Tumor se pehle hi, yeh sensor miR-21 ko khoj lega, jaise khushbu hawa mein, aur aapko bata dega, "Tum ho to khushiyaan hain!"
