Tomorrow is Valentine’s day and just in time is the “world’s tiniest” cupid. Cupid is the little guy who flies around and shoots arrows into folks and makes them fall in love. Now scientists at Brigham Young University have made a tiny cupid out of carbon nanotubes. Just a few hundred nanometers across, cupid appears to have launched his nano arrow. Now the love of your life can be smitten by a nano-gesture of your affection. Best you also send flowers or a box of chocolate.
