Nơi cuối cùng

-----

Scientists have found a previously undiscovered (trước đây chưa được khám phá) organ deep inside the human head, where the nasal (thuộc mũi) passages meet the back of the throat. Yes, the news is an extraordinary-sounding surprise, but the researchers say the discovery is likely a fourth pair of salivary glands (tuyến nước bọt)—not a second brain or transistor radio. If the findings are confirmed, this will be the first discovery of a new human organ in around 300 years.

Keen-eyed viewers may recognize that specific location as the major place where COVID-19 swabs are taken, but the new study from the Netherlands came from a different angle, so to speak. While studying patient scans, the scientists identified the almost-hidden fourth salivary glands as the cause of a rough side effect from radiology treatment of cancers.
