"Nanocephaly" Natural Recordings by Native Speakers
Nanocephaly is a rare congenital anomaly characterized by an abnormally small head circumference, usually less than two standard deviations below the mean for age and sex. It is a cerebrocranial proportion measurement that can be compared to a normal standard, and this term is used by pediatricians to describe infants who have an unusually small head size.
Nanocephaly
Nanocephaly is a rare congenital condition characterized by an abnormally small head size. Here are five usage examples:
Nanoarchaeota is a phylum of archaea, a group of single-celled microorganisms that are believed to be among the oldest forms of life on Earth. The term "nano" refers to the fact that these microorganisms are extremely small, with diameters typically ranging from 0.1 to 0.3 micrometers. Nanoarchaeota are typically found in environments that are hot, acidic, and low in oxygen, such as deep-sea vents, hydrothermal vents, and salt lakes. They are thought to play an important role in the Earth's ecosystem, particularly in the cycling of nutrients and the breakdown of organic matter.
