Scientists reveal that bacteria have ‘noses’

COMMON bacteria have “noses” that respond to smells.

A study shows how certain bugs detect the presence of rivals by picking up whiffs of chemicals in the air. The discovery means lowly bugs are now known to possess four of our familiar five senses.

They can “see” by responding to light, “feel” by reacting to physical touch, “taste” through direct contact with environmental chemicals, and “smell” by detecting airborne molecules. The only sense missing is hearing.
